3 07.11.13 The Metro Rail Design Criteria states that train control and communication roomsshall be protected with an approved non-water based special extinguishing system(such as an inergen system or equivalent), that does not damage or affect theperformance of installed equipment. In the latest revised specs it says that In traincontrol and communication room, provide hydraulically designed, single interlock,fully supervised pre-action sprinkler system, with electrically activated cross zonedsmoke detectors. Am I Correct to assume that for the train control andcommunications rooms are to have an inergen system or equivalent, with a preactionsystem? Also how are the electric service vaults, aux power, and traction powersubstation going to be protected since they are the exception to not having automaticfire sprinkler systems in them?

Contractor shall provide a water-based Pre-action Fire Protection (sprinkler) Systemfor Train Control and Communication Rooms, not both water-based and non water-based (Inergen or equivalent) systems. Paragraph 2.6.6.2 E. and 2.6.2.1 of the FLSCriteria both allow for the use of a water-based Pre-Action fire sprinkler system.Paragraph 2.6.2.4 will be revised by Metro to allow for the alternate use of a nonwater-based (Inergen or equivalent) Fire Protection System, subject to the approvalof the Agency Having Jurisdiction (AHJ). Electric Service vaults, Aux Power andTraction Power substations shall be provided with Fire Extinguishers per Paragraph2.6.4.of the FLS Criteria.”

34 07.29.13 In GC-14, 14.1.2 refers to coordination with "other contractors". Please confirm thatthe Contractor is only to consider coordination with Work by other contractors thatare clearly foreseeable under this Contract, e.g., any third party contract interferencenot related to LACMTA work and not known to the Contractor at RFP stage cannotbe considered and would constitute a change.

In compliance with General Condition GC 14, Cooperation, Coordination andAccess, in its entirety, the Design Builder is responsible for cooperation, coordinationand access with other contractors during the period of performance of the contract.This obligation is not limited to contractors that are "clearly foreseeable”; it extends toany other contractor performing work during the DB Contract period.

08.22.13

35 07.29.13 The first sentence in IP-08 B. references "conforming proposals" and "alternateproposals" which can be submitted together as "complete separate offers".However, this article also requires that alternate proposals "must be equal to orbetter than the original requirements of the Contract Documents". In addition, anyalternative proposals accepted will be "evaluated in accordance with the evaluationcriteria in this RFP." Consequently, by definition an "alternate proposal" must also bea "conforming proposal". It's therefore not clear from the description what thedifference is between the two. We request clarification on what allowances may begranted by LACMTA for alternate proposals. Also, would alternate proposals requirea complete duplicate submittal of all Vol. I, II, and III documents or just the TechnicalApproach Submittal and Alternate Price Proposal, if applicable?

Alternate Proposals must be equal "must be equal to or better than the originalrequirements of the Contract Documents". During the design and review processalternate proposals that comply with all contract requirements may be considered.Yes, all alternate proposals are considered separate and distinct proposals mustcomply with all the RFP submittal requirements.

The differences in the fan start and ramp up times used in the Fire-Life Safety BODTM and the CFD report for Fairfax will be clarified in a future amendment. The Fire-Life Safety Basis of Design (BOD) Technical Memorandum (03-27-2012) Section3.3.1 is based on the times used for the simulations in that report. These Simulationswere run allowing 90 seconds for the fans to reach full capacity after initiation. At thetime when the report was finalized, ways of improving the Time of Tenability duringthe first 4 minutes of the station fire incident were investigated, and the ramp up timewas reduced to 30 seconds. These original simulations were not rerun since thefaster ramp up time for the fans would improve conditions and at that point werealready acceptable. All CFD work going forward assumed fan activation via HeatDetector at 90 seconds, and 30 seconds for fans to reach full capacity (120 secondstotal). Table 4-1 in the BOD report was based on the initial assumptions for theproject and were based on the challenges of the Arson Based Fire.

Section 3.2 in the same report also mentions the new assumption of 90 seconds toactivate via heat detectors and 30 seconds to reach full capacity (120 seconds total).Section 01 11 01, Project Design Build Requirements will be revised to add the fanactivation and time to reach full capacity.

49 07.29.13 This section is related to deflection and distortion of the tunnel segmental lining atcross passage locations. Is LACMTA providing a quantification for deflection anddistortion?

No, Contractor to analyze tunnel based on construction methods and final tunnel andcross passage design.

78 08.02.13 Equipment access hatches up to street level are shown 12’ wide by 17’ long on theWilshire/Fairfax Station reference drawings [see Vol. IIIb, Dwg.: S-1218]. With notmuch effort it appears they could be replaced with equipment access hatches downto track level as we have track damper openings shown at large as 15’ wide X 17’long [see Vol. IIIb, Dwg.: S1214]. What is the reason for having these equipmenthatches up to street level when other equipment access hatches are provided overthe tracks below?

The floor access hatches located in Rooms 50 and 57 to track level as shown in thecontract drawings A-2111 and A-2114 (Wilshire/La Brea Station) are meant forremoval/replacement of ventilation and auxiliary power equipment only. Theequipment access hatch located in the corridor between the Traction Power Room#47, LADWP Switch Room #44, and Metering Switchgear Room #45 is required fora joint use of removing/replacing of Metro’s traction power equipment and LA/DWPequipment from the street. Track damper openings shall not be used forremoval/replacement of any type of mechanical or electrical equipment. Similararrangement shall also apply at Fairfax and La Cienega Stations.

108 08.09.13 The specifications states "Minimum 12-inch thick single-pass gasketed pre-castconcrete segmental lining". If engineering calculations and design show a thicknessof less than 12-inch meets all design requirements, would this be acceptable to theLACMTA?

NO, the Contract minimum requirement is a 12-inch thick single-pass gasketed pre-cast concrete segmental tunnel lining

08.23.13

109 08.09.13 According to the GBR (Vol. II, Section 05), the zone of elevated gas conditionsextends from Wilshire Blvd. and Highland Ave to Wilshire Blvd. and Stanley Drive.This area includes all three stations – La Brea, Fairfax, and La Cienega. However,the Project Definition Drawings (Vol. II, Section 07) drawings SF-2510 to SF-2516only shows Fairfax and La Cienega stations. Is the gas venting system required in allthree stations?

Gas venting is required at Wilshire/Fairfax and Wilshire/La Cienega Stations.Wilshire/La Brea Station is outside the elevated gas zone. GBR Section 5 andgeologic profiles in GBR Appendix A will be revised in a future amendment

08.23.13

110 08.09.13 The details shown on gas venting system appears to be intended to be inaccordance with the passive system per City of Los Angeles Methane HazardMitigation Plans, prepared by LA DBS. Please confirm.

Please see Section 31 21 16.13 Sub-Article 2.01 Regulatory Requirements and Sub-Article 2.02 System Assembly. Where appropriate for the form of construction, suchas the paved areas at the entrance locations, the City of Los Angeles MethaneHazard Mitigation Plans have been implemented. Where not appropriate for the formof construction, such as the station boxes beneath the street an alternative approachhas been implemented.

09.12.13

111 08.09.13 LA DBS requires a methane site investigation to be signed off using Form 1(Certificate of compliance for methane test data) which includes a Design MethaneConcentration and a Design Methane Pressure, together with a Methane DesignLevel (Levels I through V): was such a form prepared for the GDR for this project? Ifso, please provide.

A LADBS Form 1 “Certificate of Compliance for Methane Test Data” is not required. 09.12.13

112 08.09.13 LA DBS Mitigation Plans appear to be applied to buildings at and above grade; theydo not appear to address below ground structures. Under LA DBS Mitigation Plans,dewatering is required in order to keep groundwater at least 12 inches below thelowest horizontal pipe. At all three stations (La Brea, Fairfax, and La Cienega),groundwater level is 20 to 30 ft below ground level and the drawings show the lowesthorizontal pipe to be at least 80 ft below ground level. The drawings also refer to‘submerged trench drains’ which we assume are water-filled: Can we assume thatthe gas venting system shown on the drawings could be entirely filled with waterbelow groundwater level?

See Section 31 21 16.13 Sub-Article 2.02 System Assembly for the minimumrequirements of the gas venting system. LADBS Mitigation Plans are written forbuildings and hard paved areas and the Project Requirements are written to addressbelow ground structures. It can be assumed that the gas venting system shown onthe drawings can be entirely filled with water below groundwater level.

09.12.13

113 08.09.13 Can the design basis for the sizing, layout and spacing for the underslab and verticalriser systems shown on the drawings for La Cienega and Fairfax Stations beprovided?

The design basis is from the City of Los Angeles Methane mitigation measuresmodified for Metro’s underground facilities.

09.12.13

114 08.09.13 The sidewalk vent details show risers discharging into either a below grade boxcovered by a steel grating or a landscape buffer zone detail. There are scenarioswhere such systems cannot disperse methane: for example, if the steel grated box isfilled with accumulated soil or trash or if the landscape buffer zone is filled with rainor irrigation water. Who is responsible for maintaining these vents so that theyfunction properly?

During the Project the Contractor is responsible and on Project completion, LACMTA is responsible for maintaining the vents. Both details are similar to thoseused in the City of Los Angeles and are developed from the LADBS Mitigation Plans

Letssays decking comes out at day 2700. Then demobilization must complete by 2700 +3250 = 5950. 6950 / 365 = 16 years after NTP.


120 8.23.13 Please explain why alignment vertical profile adjustment is restricted to 5ft upwardand 30ft downward? Does the restriction apply to the top of rail elevations at eachstation?

General Requirement Section 01 11 01 Paragraph 2.20. J.1.a.3 will be revised in afuture amendment to remove the constraint on profile deviations in the vertical plane.The track alignment may be realigned from that shown so long as it remains within 5-feet from the Right-of-Way limits. As part of Project planning and design for energyconsumption (Refer to Section 35 63 Sustainability Plan), the track vertical profileshall be designed with a vertical profile sag between stations to minimize train energyconsumption during breaking and accelerating on approaching and leaving thestations respectively.

Metro would consider a “better design” that is compliant to allthe Project Definition Drawings, Technical Requirements, Metro Design Criteria,Metro Standard Drawings and all other mandatory Contract Documents. The “betterdesign” will need to be cost effective as lowest price is part of the proposalevaluation criteria. All “better designs” must conform to all technical requirementsand be responsive to the RFP solicitation.

AnswerQuestion

123 8.23.13 Amendment 1 includes a design deviation approval of architectural directivedrawings. Does it imply that any design features that are not identical to the MetroDirective Drawings require deviation approval? To our understanding, the intents ofthe Metro Standard Drawings are mandatory, but the intents of the Metro DirectiveDrawings are not, except mandated contractually otherwise. Is our understandingcorrect?

Design features that are not identical to the Metro Directive Drawings DO NOTrequire deviation approval. Metro Standard Drawings are mandatory, but MetroDirective Drawings are not mandatory except if the information shown on the MetroDirective Drawing is a technical requirement elsewhere in the RFP.

125 8.23.13 A TBM arrival shaft is prescribed west of existing Wilshire/Western Station, inanticipation of TBM launching from Wilshire/La Brea Station eastward. However, wedon’see any prescription of an arrival shaft at the west end of the tail track. Pleaseexplain Metro’s position and intent about how to terminate bored tunnel thereof.

Please refer to Drawing G-2450 for the termination at tail tracks. This may requireportions of TBMs (shields) to remain in place, with other components salvaged thruthe tail tracks and Wilshire/La Cienega shaft excavation. A retrieval shaft at the westend of Section 1 was not contemplated at the time of the EIS/EIR and cannot becleared in time for Section 1.

09.04.13

126 8.23.13 Will Metro consider and accept construction methods other than cut-and-cover orbored tunneling for stations, X-overs, and tail tracks? For example, the RegionalConnector project prescribes the use of SEM for X-over cavern construction.

Metro has anticipated Sequential Excavation Methods (SEM) for cross passages inthe GBR. Westside Subway Extension stations and crossovers, to be constructed insoft ground, may not be excavated using SEM. Tail Track excavation by tunnelingmethods other than pressurized face TBMs may be acceptable subject todemonstration of meeting project requirements, such as those in TechnicalRequirements Section 31 71 16 - Mined Cross Passages. Note that Cut and Covermethods are not acceptable for tail track construction.

128 8.23.13 What is Metro’s position on the migration of contaminated groundwater at the stationsites, where construction dewatering would induce such a movement should soliderpile with lagging wall system is deployed as the mean of stability of excavation?

Regarding the movement of the contaminated groundwater as a result of dewatering,Contractor is responsible for the treatment and disposal of contaminatedgroundwater that is discharged from a dewatering system or from the excavation.

11.01.13

129 8.23.13 A 4 (four) inch construction tolerance is shown on the bored tunnel typical section.Are we allowed to adjust the tolerance to fit our tunneling control?

Tolerances shown are maximum allowable. Tighter tolerances are acceptable topromote better tunnel build and reduce potential need for track adjustments

08.28.13

130 8.23.13 Does Metro’s HRT vehicle dynamic envelope consider end throw? We understand the term ‘end throw’ in the question to mean the train overhang(either mid-overhang or end-overhang) as the train travels through a curve. TheMetro Dynamic envelope does not take account of this. For these dimensions, referto Section 4 of the Metro Design Criteria, and in particular Figure 4.16. In addition,refer to Project Definition Document drawing Y-2005 (Sheet 233) which shows theoffset dimensions for the centerline of track from the centerline of tunnel for thecurves in the project alignment.

150 09.04.13 Section 01 11 01-17, Project Design-Build Requirements, clause 3.03 A.5.astipulates "Special excavation methods as defined in the GRB with no more than 6inch lifts are a project specific requirement within the Paleontological Zone……….".Since the 6 inch lifts are most likely to be executed by hand mining over weekend fullroad closure periods, it would be almost impossible to achieve a depth (about 6ft)sufficient for decking/supporting beam installation in any given weekend closure of53 hours (Friday midnight to Monday 5am), and restore surface traffic. Will Metroreconsider the lift restriction?

Due to street closure time constraints, 6 inch lifts will not be required for deck beaminstallation and utility relocation, up to a depth of 10 feet below the ground surface.Metro has assumed the use of raised decking in the design of the advance utilityrelocations. The raised deck installation reduces time of excavation in theWilshire/Fairfax area for deck beam excavation and potential disturbance ofpaleontological resources. This will be clarified in a future amendment.

174 09.13.13 Our understanding of Paragraph A. is that contractor JV members, which aresubsidiaries of parent companies (and use their parent companies’ projectexperience and execution capabilities), will not be required to provide a ParentGuaranty at Proposal submission, but may be required to provide one post-bid. Isthis correct?

Not required at Proposal Due Date although IP-13 (18) Metro has the discretion torequire a Parent Guaranty.

AnswerQuestion

Is ALL tar contaminated soil required to go to a class II landfill or (dependent on testresults) is it allowable to send a portion of the material to a class III facility?-Per Environmental Procedures for Contaminated and Hazardous Materials, 01 3543-6: All tar contaminated soil shall be disposed of in a Class II landfill. However, thisconflicts with the EDR (pages 93 and 94 of 102), where it states the following: 91% ofthe tar impacted soils from the Wilshire/Fairfax Station were initially considered to beNon-RCRA Hazardous Waste (California Hazardous Waste) per CaliforniaRegulations, but later classified to be non-hazardous for disposal purposes whenthey passed the Bioassay Fish Kill Test. However, due to the presence of tar in thesoil, most of the excavated materials may require disposal at a Class II Landfill facilitysuch as McKittrick Landfill (located west of Bakersfield). It is anticipated, that aportion of the excavated material from this location can also be disposed off at aClass III Landfill facility, provided favorable test results from Bioassay test areestablished during station excavation

operations and no excessive tar balls are encountered. If the Bioas say results areunfavorable then the excavated material will require disposal to a Class II Landfillfacility such as McKittrick Landfill.

188 09.27.13 Members of our team have recently completed Metro Exhibit C Experience /Performance Questionnaire forms that were submitted for another recent Metrodesign-build proposal. Will Metro accept these same forms for the WestsideExtension proposal?

Yes, as required in the RFP documents. 11.15.13

191 09.27.13 Will Metro be revising the Form 3’s for Design and Construction to include changesmade to columns C-G on these forms as was done for the Regional Connectorprocurement?

To be revised in future amendment. 10.04.13

The tar will likely be non-hazardous based on the bioassay test that was alreadyconducted. However, if the soil has high VOCs, even if it is non-hazardous, it canonly go to specific facilities, such as Thermal Remediation Solutions facilities. If soilhas low VOCs and is non-hazardous, then it can go in to a class III facility that canthat accepts that level of TPH.

192 09.27.13 Section 01 11 00 - 9, paragraph 1.04.B.1 states: "Prior to Contractor access to astation or shaft location, Metro will have relocated utilities inclusive of;telecommunications, electrical power, gas, sewer and water mains that run parallelto, and within the planned Pile Corridor." This statement omits "storm drain",presumably on purpose. However, the Contractor Utility Responsibility Matrixprovided in section 01 31 31 states that the 1045 contractor will only need tosuspend/protect the storm drains. Additionally, the project definition drawings call outthat the 1045 contractor is to relocate the storm drains. (See PDD Sheet 161 for anexample at La Brea Station). Please clarify who is responsible for storm drainrelocations.

To be clarified in next amendment. 10.31.13

193 09.27.13 The La Brea Station 1048 Advanced Utility Contract drawings provided inamendment 1 show a 36” HDPE sanitary sewer (SS). See sheet 082, cross section2. This SS is not shown on any of the project definition drawings in the 1045 RFPpackage at La Brea Station. It appears this 36” SS will remain in place and requiredto be hung by the DB Contractor on the 1045 contract, please confirm.


194 09.27.13 Section 3.03 on page 12 of 01 31 31 states that "The Contractor is responsible forthe design and construction of storm drain and sanitary sewer relocations...". This isin conflict with both the Responsibility Matrix in this same section, and also the scopeof work document, specifically section 01 11 00-9, paragraph B.1 which states that allsewer lines will be relocated ahead of time by other contracts. Please confirm thatthe contractor is not responsible for sanitary sewer relocations.


195 09.27.13 Sheet 161 of the project definition drawings shows an 18" sanitary sewer that is to berelocated by the DB contractor at La Brea Station. Upon reviewing the La BreaStation advanced utility contract documents, it appears the 1048 contractor is beingdirected to relocate this sewer line. Please clarify who will be relocating this sewerline.


196 09.27.13 It is not clear what is Mandatory in the context of GC Para 44. For instance, reading01 11 01 Project D/B Requirement Para 2.02C.1.a. it remains unclear what portion, ifany, Metro considers Mandatory. Advise if any words such as 'shall', 'will', 'are fixedas a Project Specific Requirement', Project Specific Requirements' are equivalent toMandatory. Q&A 123 may have further confused items as it defined those items inthe Directive Drawings and shown in the Technical Requirementsare now mandatory.

Words such as “shall” or “will” or phrases such as “are fixed as a Project SpecificRequirement” indicate that the item referenced is a requirement. As a general rule,the particular requirement referenced sets forth the minimum technical and/orperformance characteristics of the Work that must be met; however, in some casesthe particular requirement referenced must be met exactly, for uniformity purposes.All RFP requirements are “mandatory” as that term appears to be used in thequestion. GC- 44 will be clarified in a future amendment.

197 09.27.13 Section 01 35 63 Para 1.01.C states compliance is required for both 'Mandatorysustainability measures as well as voluntary sustainability requirements'.This conflicts with the same Section, Para 3.01.A that states 'The Sustainability goalsfor the Project, as a minimum, are to efficiently implement the mandatorysustainability measures as listed in the Sustainability Measures Checklist from theCurrent Edition of California Code of Regulations (CCR), CALGreen, Part 11 of Title24, Please clarify if only 'mandatory' or both 'mandatory and voluntary' items arerequired. If voluntary is also a requirement, confirm which Tier (Tier 1 or 2).

These paragraphs are not in conflict. Contractor is to comply with 2013 CalGreenrequirements through the minimum implementation of the mandatory sustainabilitymeasures listed therein. If Contractor chooses to implemented voluntary measures,to the fullest extent feasible, Contractor to meet Tier 1 requirements but encouragedto meet Tier 2 requirements. These requirements are, however, superseded byMetro sustainability and environmental related policy requirements, as applicable. Please refer to Volume IV "Other Contract Documents" or go towww.metro.net/ecsd for copies of Metro's sustainability and environmental policy andplans.

198 09.27.13 MRDC 2.3.2.2 indicates the ventilation system shall be designed meeting certainperformance criteria when the 'most critical fan will be assumed out of service'. Oneperformance criteria for HRT is a FHRR of 86.5MBtu. The PE Tunnel and StationVentilation Report, para 4.3.7 'Performance Criteria' states the 'one fan out' appliesonly to a single car fire (FHRR of 43.6MBtu). Is a deviation report expected forthe MRDC 2.3.2.2? NOTE: MRDC in 8.1.4.D does indicate the 'one fan out of servicefor one car fire'.

The MRDC (Mechanical 8.1.4.D) and PE Tunnel and Station Ventilation Report weremodified as stated in the “Fire Life Safety Basis of Design” report (03-27-2012),paragraph 1.1 Design Fire Properties. This change was agreed upon by the FLSCfor this project since the stations have fire sprinkler systems that will prevent thespread of the fire from one car to the next. Changes to the criteria are reflected in theMechanical Criteria (8.1.4.D). Section 01 11 01, Project Design Build Requirementswill be revised to include a single car fire with the most critical fan out of serviceduring a station fire. The Metro Fire Life Safety Committee will modify MRDC 2.3.2.2to reflect “one fan out with a single car fire with FHRR of 43.6MBtu”, as is currentlystated in the MRDC (Mechanical 8.1.4.D), and the PE Tunnel and Station VentilationReport and the Fire Life Safety Basis of Design Report of 03-27-2012 as part of theirnext update to the FLS Criteria.

199 09.27.13 Spec section 14 31 00 Escalators (warranty starts at Substantial Completion) seemsto conflict with GC-23 Warranty (warranty starts at Final Completion, or 12 monthsafter SC). Thus, Escalator warranties could expire 12 months prior to the Project'sother standard warranties. Confirm if the Escalator spec is an exception and theconflict is not to be reconciled with Art I Precedence. Also, GC 23.2.1 states:'Subcontractor’s, manufacturer’s or Supplier’s Warranty Periods shall be for thelonger of the above stated Warranty Period or the Warranty Period specified in theparticular Warranty'. To what does 'particular warranty' refer? The manufacturer'sstandard commercial warranty? A Technical Requirement special warrantyrequirerment? Something else?

The Escalator and Elevator Warranties are an exception to GC-23 and will start atSubstantial Completion. At Substantial Completion the 1 year Warranty as well asthe 1 year Preventive Maintenance period will commence. The “particular warranty”refers to the specific warranty that is provided by the subcontractor, manufacturer, orsupplier. So the warranty period for these warranties will be the longer of the periodset forth in GC-23 or the period set forth in the subcontractor’s, manufacturer’s, orsupplier’s warranty. If escalator and elevator supplier warranty in in excess of the 1year, the longer warranty will apply as per GC-23.

With the vaults andmanholes referenced above having dimensions of 9’-4” x 17’-6” x 12' 4" as shown onSheet U-379, there is a strong potential for the deck beams to conflict with thestructures. Would it be possible to turn the structures 90 degrees so that the longestsection of structures are perpendicular to the station and re-orient the duct banksaccordingly? This would eliminate the potential conflict with deck beam installation.The same condition would be a potential issue to consider for all stations.

225 10.16.13 The Geotechnical Baseline Report (Vol. II, 05) provides pH design values in TablesC-1, C-2, and C-3 lower than 4.2 (except for 3 soil types). These values aresignificantly lower than report 4.02 Corrosion Control Measures TM (Final) (2-14-2012) (Vol. IIIa,0,4) which states “2.1.1 Soil pH ranged from neutral to moderatelyalkaline and was not indicative of corrosivity. Page 28 of 115 states ‘Soil pH valuesvaried from 6.7 to 8.4’ ”. Note that the low GBR pH design values indicate a highlycorrosive environment and requires external protection to the precast segmental linerand the segment gaskets to ensure a 100-year design life, which does not appear tobe included in the reference design. Please clarify this apparent discrepancy andconfirm if the GBR values are correct.

The Corrosion Control Measures TM is a Reference Document. Additional data hasbeen gathered and reported in the Contract Geotechnical Data Reports.

226 10.16.13 Regarding archaeological and paleontologic requirements for the Purple Line project,it appears that the RFP, MOU, and MMP requirements are not consistent with eachother. There are only a few paleontologic firms that know how to work in the soilsnear the Tar Pits and that are approved by the George C. Page Museum of La BreaDiscoveries. Since Metro has a standard 5-year contract with an environmentalcompany that fulfills standard archaeological and paleontological services as part ofthe contract, is this firm to provide paleontologic services on the Purple Line or is aspecialized firm to be hired for this work under a project specific contract?Additionally, does Metro hire the specialty firm or does the Design/Build team?

230 11.02.13 We have reviewed the Traction Power Simulation Report and from our analysis ofthe proposed reference design, this will meet the operational requirements with bothSections One and Two of the Westside Extension complete. However, with onlySection One in operation, the reference design will not support the requiredoperational performance, requiring an additional TPSS to be added until Section Twobecomes operational. Please advise if the additional TPSS is required for this interimperiod while Section One is operating without Section Two.

No additional TPSS is required for this interim period while Section 1 is operatingwithout Section 2 as Metro Operations is not planning to operate 6 car train / 4-minute headway during Section 1 operation. Two-4000 kW rated substations at theindicated locations on the TP Load Flow Simulation report of RFP Volume III, areadequate for the Section 1 system operation.

Please clarify the party responsible for the oil/gas well investigation.Contractor's scope of work on oil/gas wells per General Requirement 01 35 29 is "Closure, drainage, sealing, excavation, removel, transport or disposal of oil or gaswells or casings (Gas Casings)...". Also, "Party Responsible for ImplementingMitigation" for "Further Research on Oil Well Locations" is Metro according toAttachment A Mitigation and Monitoring Reporting Plan after Section 01 35 44.

Indicating seven wells within the tunnel alignment, however, the GeotechnicalBaseline Report says, "In the area where abandoned oil wells could potentially beencountered, probe holes ahead of the face and geophysical survey to detectobstructions will be required. If an abandoned oil well is detected underground aheadof the face, and evaluation of its condition and its abandonment must be carried outin accordance with appropriate regulations." and "All seven well locations must beinvestigated to establish which are within the construction work. Investigations shouldcontinue until all sites are fully explored even if abandoned wells are identified."

These sentences seems to mean that Contractor should do well casing survey.Please clarify

236 11.02.13 GC-25, Section 25.2 Repair and Replacement stated that: “Unless otherwiseprovided, Contractor shall repair or replace all existing structures, equipment, andvegetation damaged or removed by Contractor. Repairs and replacements shall be atleast equal to the existing structures, equipment, or vegetation, and shall match...”Section 25.3 Costs stated that: “All costs for protecting, removing and restoringexisting structures, equipment, and vegetation shall be the sole expense ofContractor. If Contractor fails or refuses to make timely repairs, restoration orreplacement LACMTA may make the repairs, restoration or replacement. All costsincurred by LACMTA, as determined by LACMTA, for such repairs, restoration orreplacement shall be repaid.”Would these two Sections GC 25.2 and 25.3, especially Section 25.3, be applicablefor adjacent building damage, if any, due to building settlement and distortion lessthan the maximum allowable defined in the Technical Requirements?

238 11.08.13 Per Metro Rail Design Criteria, 2.1.3.3, page 2-2, whichstates “Construct all newfacilities and projects, including new transit corridor projects, using energy-efficiencyand conservation strategies. For buildings or structures over 10,000 square feet,projects must be constructed to achieve Leadership in Energy and EnvironmentalDesign (LEED®) Silver certification, at minimum.” Please clarify if the Silvercertification provision is applicable to underground facilities like underground stationsand underground guideways? Or which particular facilities within the project aresubject to the Silver certification requirement?

Per Metro policy, each new Metro facility greater than 10,000 square feet must bebuilt to achieve LEED-Silver certification. Metro seeks justification and would reservethe right to grant variance to Metro policy if LEED is not achievable for anyinfrastructure or building greater than 10,000 square feet that is built for the project.Related sustainable features and best practices are to be identified in the requiredSustainability Plan submittal and implemented during the project, regardless of LEEDcertification.

Please reference schedule of quantities and prices form schedule A, bid item 46“Incremental Cost for Excavation, Segregating, Hauling and Disposing ofContaminated (nonhazardous) Soils to Class II Landfill above cost for cleansoils” with an estimated quantity of 500,000 tons. In addition, please referenceGeneral Requirements, Section 01 35 43, Paragraph 3.03.E. which states, “Unlessotherwise directed, all tar contaminated soils shall be disposed of in aClass II landfill.” This bid item indicates that we may only provide pricing for aClass II Landfill. Please note the Class designations developed by the State ofCalifornia are not correlated with the threshold levels of acceptance. For example,the TPH threshold levels of acceptance at some Class III landfills arehigher than the TPH threshold levels at available Class II landfills.There is data and language contained within the Environmental Data Report datedMay 22, 2013, which supports that some of the tar sands or contaminated soilswould fall within the thresholds limits and thus be acceptable for disposal at a ClassIII Landfill.

Furthermore, there is data that shows TPH limits will exceed the thresholdsacceptable at either Class II or Class III landfills. As such, it appears the tar impactedsoils material may require disposal at a Class I landfill or its out-of-stateequivalent of a Subtitle D Landfill. Note: Classification of landfills such as the ECDClandfill does not fall within the classification guidelines established by the State ofCalifornia and are referred to as Subtitle D Landfills. The inference that disposal mayonly occur at a Class II Landfill severely limits the disposal options.Please clarify if disposal and payment for this item could include: Class I Landfills,Class II Landfills, Class III Landfills within California and/or Subtitle D FederallyRegulated Landfills located outside the state of California. We would suggestcreating separate bid items for disposal at Class I landfills, Class II landfills, Class IIIlandfills and Subtitle D Landfills.

Reference the Environmental Data Report dated May 22, 2013, starting on page 4-21 last paragraph under Wilshire/Fairfax station and continuing on to top of page 4-22 which states, “Based on the results of analytical testing, 91%of the tarimpactedsoils from the Wilshire/Fairfax Station were initially considered to be Non-RCRAHazardous Waste (California Hazardous Waste) per California Regulations, but laterclassified to be non-hazardous for disposal purposeswhen they passed the Bioassay Fish Kill Test. However, due to the presence of tar inthe soil, most of the excavated materials may require disposal at a Class II Landfillfacility such as McKittrick Landfill (located west of Bakersfield). It is anticipated, that aportion of the excavated material from this location can also be disposed off at aClass III Landfill facility, provided favorable test results from Bioassay test areestablished during station excavation operations and noexcessive tar balls are encountered.

If the Bioassay results are unfavorable then the excavated material will requiredisposal to a Class II Landfill facility such as McKittrick Landfill.” Reference resultsshown for TPH shown on page 3-36 for borings E-115, E-115A, E-115B, E-116(Fairfax Station); several of these results exceed the thresholds for acceptance at aClass II Landfill such as McKittrick. Based on review ofMcKittrick’s Landfill current threshold limits for TPH and other regulations it isunderstood the only way McKittrick Landfill would accept this material would be if theBioassay test results are favorable which conflicts with the statementquoted from the Environmental Data Report above which states “unfavorable”. Inconclusion, materials such as those shown in the borings at Fairfax Station thatexceed thresholds and do not pass the Bioassay test results for a Class II Landfillsuch as McKittrick would only be able to be disposed of at a Class I landfill inCalifornia or Subtitle D landfill outside of the State of California. Furthermore, eventhough thresholds may exceed the limits prescribed for McKittrick Landfill such material would not necessarily be considered hazardous.

Please clarify bid item 46 which limits disposal just to a Class II landfill? We wouldsuggest creating separate bid items for disposal to: Class I landfills, Class II landfills,Class III landfills and Subtitle D Landfills.

250 11.11.13 Spec Section 26 32 13.13 covers the Standby Generator(s) and calls for load banksin Paragraph 2.01 M. Article 2.13 further specifies the load bank shall bepermanently installed and sized for full load rated capacity of the standby generator.However, there are no additional features or performance specifications provided.

Drg E-2040 (Standby Power Single Line Diagram) also agrees with this for both theLa Brea and La Cienega Stations, with a similar description in Reference Note 13.

However, the Typical Generator Enclosure Drawing E-0021 does not allocate aspace for this load bank. A typical freestanding 2000 kVA load bank is about 4 footby 7 foot and requires 34,000 cfm of airflow with appropriate clearances. If the intentof the specifications is that the load bank be internal to the genset package withradiator airflow as the cooling medium, the maximum radiator-cooled load bank thatcan be used will only be 50% of the generator full load rating.

Spec Section 26 05 05-14 describes the Standby Power Supply (SPS) System inParagraph 1.08 B, but there is no mention of a load bank.

A permanently installed load bank is to be provided for each standby generator andhave the capability of testing the full load capacity of the standby generator asspecified in Section 26 32 13.13 Standby Generator – Articles; 2.01-M., and 2.13-A.The load bank is to be located in the exterior walled areas surrounding the generatorsound attenuating housing, located in the station entrance area. Its exact location willdetermined in the Contractor’s Final Design.

11.15.13

251 11.11.13 Please confirm if the generator enclosure, panel, and fuel tank arrangement can bemodified from the reference design.

This will depend on the type of modification. The generator layout design shown isconsistent with the contract specification Section 26 32 13.13 - Standby Generators,with a prefabricated stand alone generator housing with sound attenuated enclosure,a fuel oil system, and a skid mounted fuel tank located below the generator that willbe pre-tested at the factory as a single generator unit prior to delivery. The reasonsfor this design configuration are two-fold:

1. To provide standby generator design that can pre-fabricated and tested at an off-site facility prior to delivery to minimize field testing problems.

2. To provide a standby generator design that can be upgraded and/or serviced as acomplete unit.

Designs that comply with these specifications are acceptable. Designs that include anon-integrated pre-fabricated fuel oil supply and delivery system as part of thefactory pre-fabricated generator unit will not be acceptable.

252 11.11.13 Referring to Addendum #3, additional dampers have been included for Crossoverstations. Please advise as to the size of the dampers, or issue drawings withdimensions for measurement.

259 Refer to Specification Section 26 05 19 Insulated Wires and Cables Article 2.01.AGeneral Requirements and Article 2.03 Cables regarding cable assemblycomponents (including conduits) for fire/life safety system conduits and non fire/lifesafety system conduits. Fire life/safety system cable assemblies shall be compliantwith UL 2196 listing requirements for 1 hour and 2 hour rated cable assembliesbased on its application and location.

GRS conduit can be used for exposed non-life/safety system conduits.

GRS conduit cannot be used for exposed life/safety system conduits that require aUL 2196 1 hour and 2 hour listing, per the recent UL 2196 Standard for 1 hour and 2hour cable ratings.

All exposed conduits and cable assembly components shall comply with Metro’scorrosion control requirements, which is equivalent to a minimum NEMA 4X rating.

To comply with NFPA 130 requirements for exposed 1 hour rated egress lighting andLife safety system communication conduits and cable assembly components, analternate to GRS conduit must be provided that is compliant with the UL 2196 1 hourand 2 hour listing requirements.

Fiberglass “Phenolic” FRE heavy wall conduit may be acceptable alternative to GRSconduit for 1 hour and 2 hour UL 2196 listed cable assemblies. In addition Fiberglass“Phenolic” FRE Nema 4X boxes may be acceptable alternative to Stainless SteelNema 4X boxes for 1 hour and 2 hour UL 2196 listed cable assemblies. However,the specific cable assembly components would require certified UL testing to verifythe cable assembly compliance. In addition it should be noted that Fiberglassphenolic FRE boxes will not provide protection from EMI.

The only current UL 2196 1 hour listed compliant option for station and tunnel lightingbranch circuiting is metal clad cable 1 hour rated per current UL 2196 listingrequirements.

Embedding GRS conduits in 2 inches of concrete with RHW cable will comply withUL 2196 1 hour and 2 hour cable assembly listing requirements, will protect conduitsfrom being crushed, and will provide protection from EMI. In addition, all componentsof cable assemblies that require a 1 hour or 2 hour UL 2196 listing, includingembedded pull/splice boxes where the cable assembly transitions from embedded tosurface mounted.

The Contractor’s cable assembly design components shall comply with applicableUL 2196 listing requirements for 1 hour and 2 hour cable assemblies based on thecable assembly classification as ‘life/safety’ or ‘non-life/safety’, metro corrosioncontrol requirements and Metro’s EMI protection requirements.

11.11.13 Metro Rail Design Criteria 7.10.1 States that Rigid Steel Conduit shall be used for allexposed work in dry areas not likely to present corrosion problems. These conduitsshall be embedded in slabs where protection against EMI is required and in slabssubjected to high impact. The review of the reference documents also shows the useof GRS conduits at exposed and embedded locations in the stations and tunnels.Please clarify that is the intent of Metro to use GRS conduits in embedded concretewithin stations and tunnels.

267 11.11.13 The disposal of Gasoline range Hydrocarbons (Section 01 35 43 1.06 C.2), gasolineconstituents BTEX (Section 01 35 43 1.06.4), or other VOCs is not defined in thedocuments. Class II landfills are specifically designed with liners and leachatecollection for wastes that have leachable contaminants. Tar is generally notleachable whereas the other contaminants formally mentioned are leachable. Ourassumption is that disposal location options presented in the document "SoilDisposal Facilities Options Summary" are approved facilities (Section 01 35 433.03.D "Dispose of all contaminated materials at a Metro approved Waste DisposalFacility") Please confirm this assumption is correct.

Disposal of waste at a “METRO Approved” facility is required so Metro will havesome control over where the Contractor proposes to dispose of the generated wastestreams.

The Contractor can either use one of the pre-screened facilities Metro has providedin the Waste Disposal Fact Sheet , or should the Contractor wish to use a facility noton that list, the Contractor needs to submit the pertinent information on the wastestream, the proposed facility’s permits and criteria for acceptable waste, etc.information to Metro for approval.

AnswerQuestion

279 11.12.13 Amendment 3 includes Architectural drawings showing a new tunnel ventilation ductconnecting the Fan Room with a ventilation plenum on the tunnel side of thecrossover at La Cienega and La Brea Stations. The new ducts appear to extendfrom the Fan Room across the top of the back of house spaces at concourse level tothe vertical plenum connecting them to track level. No information is includedindicating the size of the duct, although the revised MEP Revit models appear toshow plant has been moved to accommodate a duct.It appears that the intent is to improve the effectiveness of the tunnel ventilationsystem when it is extracting smoke from the bored tunnels on the cross-over side ofthe station, but no information is given as how the system will actually achieve thatgoal or the operational requirements. Please provide a description of the operationalrequirements of this duct (i.e. is it intended that only one tunnel at a time will beserved) as well as the size of the duct and the airflow required.

The new plenum will extend from the existing fan plant shown in the RFP Submissionto a shaft at the end of the back of house spaces to extract air and/or smoke fromeither tunnel without affecting the crossover. These requirements described inAmendment #3, 01 11 01 - Project Design-Build Requirements, paragraph 2.02Performance Criteria H.1.b and c. The final size of the plenum and associateddampers shall be determined by the final designer through calculations and analysisbased on the final design.

(For example, if there is a fire in one tunnel with evacuation away from the crossover,smoke would be extracted from the crossover/tunnel interface thereby confining thesmoke to one side while keeping the crossover free of smoke.)

However, when the constraint that no more than one train perventilation zone is added to the design this parameter of a two minute headwaycannot be achieved between La Brea and Western. This was also confirmed in yourRail Operations Simulation Report (Final-Rev 1) Task No. 5.2.7 (Deliverable No.5.2.7.B), recently issued, which indicated that an additional vent zone must becreated if an 18 trains per hour (TPH) schedule was required. Given that thereference design does not include the additional vent shaft, are we to presume thatan extended headway for train operations of 4 mins (15TPH) is acceptable.

Yes, the requirement is for a 4 minute headway on the branches, 2 minutes in the“trunk” between Wilshire/Vermont and Union Station.

294 11.22.13 Please provide the date bidders can anticipate receiving the results from theenvironmental surveys at the buildings to be demolished within the ConstructionStaging Areas allowing us to incorporate these findings into our proposal and avoidpricing undue risk.


295 11.26.13 Environmental Impairment Liability Site Coverage: We recommend amending therequirements for a policy term of not less than 15 years from the inception ofcoverage. Current market conditions support a 10 year term period for this type ofcoverage.

We concur. LACMTA will revise the requirement to a policy term of not less than tenyears.

12.05.13

296 11.26.13 Professional Liability: Would LACMTA entertain a "Linked Limited" program structurein which an insurer issues separate policies for the Design/Builder and the Designerthen share the required $50M aggregate limit?

No. The limits and terms of the project professional liability policy are intended topreserve the full $50 million in limits for the LACMTA and Third-Parties.

12.05.13

297 11.26.13 Builders Risk: Please advise if coverage is required for the Tunnel Boring Machines,or if self insurance for the TBM’s is allowed.

Coverage is required for the Tunnel Boring Machines. 12.05.13

298 11.26.13 Builders Risk a.: For tunneling exposures, Munich Re 101 is required to provide120% of the replacement cost. 135 % is frequently provided, and higher limits arerecommended due to the costs associated with restoration after a collapse. WillLACMTA revise the requirement to 135% or higher to provide consistency amongbidders?

No. LACMTA will not agree to revise the requirements. 120% of the replacementcost is the minimum requirement. Proposers may choose to self-insure or to insurethis exposure in excess of the minimum limits at their discretion.

12.05.13

299 11.26.13 Builders Risk b.: A loss limit of $200 million is required. Please confirm LACMTAretains the risk of loss in excess of the $200 million loss limit.

AnswerQuestion

302 11.26.13 Builders Risk c.: Can the LACMTA provide a definition of exactly what is meant by"bona fide earthquake" or a sample endorsement? This would be useful in carvingthe coverage out of the requested earth movement coverage.

Insurance companies use a variety of definitions for what constitutes an earthquake.Generally these definitions do not conform to the definition in statute as “earthquakesin excess of a magnitude of 3.5 on the Richter Scale” (California Public ContractCode Section 7105). The intent of this language is to ensure that ALL earthmovement is a covered peril EXCEPT for an earthquake. The statutory definitioncan certainly be used by proposers to define the earthquake exclusion for theBuilder’s Risk coverage. If proposers do so, the policy then would state that all earthmovement would be a covered peril except for an earthquake in excess of magnitude3.5 on the Richter Scale.

12.05.13

303 11.26.13 Verification of Coverage a.: Copies of all policies are required within 90 days of NTP.Many of the policies may not be issued by that point. Will the LACMTA considerchanging this requirement to 180 days?

LACMTA will change the requirement to 180 days. The contract provision will berevised to reflect the period.

12.05.13

304 11.26.13 Will the exploratory shaft test tie-back report be available to the design-build teamsprior the RFP due date?


305 11.26.13 Many DBE and non-DBE subcontractors and suppliers will not be working over theholiday season. We anticipate minimal pricing from subs and suppliers for theJanuary 3rd deadline. We respectfully request the RFP deadline beextended.


306 11.26.13 Reference Technical Specification Section 01 78 43: List “A” Spare Parts -Trackwork Item 7 “Frog” 2 each. Please clarifythe 2 types.

The requirement is for 2 spare frogs of each type installed. Required number ofspares will be determined by the Contractor’s trackwork design. If more than onetype of frog is installed, then the Contractor is to provide two spares for each typeinstalled. If only one type of frog is installed per the Contractor’s design, then therequirement is for only two spare frogs.

12.04.13

307 11.26.13 Reference Technical Specification Section 01 78 43: List “A” Spare Parts - ContactRail Item #6 and Item #8; anchor assemblies. There are 2 anchor assembly itemswith different quantities, please clarify.

Do not include in the Proposal the price for Technical Specification Section 01 78 43:List “A” Spare Parts - Contact Rail Item #8; anchor assemblies.

12.04.13

308 11.26.13 Reference Technical Specification Section 01 78 43: List “A” Spare Parts - ContactRail Item 7 Support Insulators. What are the types? Are they Porcelain/Fiberglass?

To match what was approved and installed. 12.03.13

309 11.26.13 Will the LACMTA consider an alternative structure to a Project Professional Liabilitypolicy naming the DB Contractor and all Contractor Related Entities?The alternative structure is Design Team Project Professional Liability policy with a$25 million limit and a Contractor Protective Professional Indemnity Project policywith a $25 million limit. This would provide $50M in Professional Liability limits to theproject, as required by the contract. The primary advantage of this structure over thestructure required in the insurance specifications is that if claims made by theContractor against the Contractor Related Entities’ Project Professional Liabilitypolicy will not be excluded via an “Insured versus Insured Claims” exclusion.

No. The limits and terms of the project professional liability policy are intended topreserve the full $50 million in limits for the LACMTA and Third-Parties.

1. LACMTA will revise the requirement to a policy term of not less than ten years.

2. Phase I and Phase II environmental assessments. Phase II where the site isaccessible. Ground water and boring data is available and has already beensupplied. Additional Phase I’s and Phase II’s will be provided when available.

3. Some assessments have been completed and some are in progress. MTA’sProcurement Team can be asked for additional copies and will distribute newdocumentation when it becomes available.

4. Completed reports are currently available and distribution is pending. Reportscan be provided to carriers.

5. The Environmental Indemnification in the contract language limits the ProjectTeam’s liability. LACMTA does not carry environmental liability insurance coverageor construction coverage and does not maintain a brokerage relationship to placethis coverage. Contractors have better access, knowledge and relationships toleverage to affect placement with better terms and pricing.

6. LACMTA understands that the degree of Environmental coverage will depend onthe environmental information available. Negotiations and discussions during thechange order process should result in appropriate coverage.

311 11.26.13 Amendment #4 contained an updated set of Metro Architectural Directive Drawingsthat includes a reduced Portal Canopy and glass partition around the entrance stairsand escalators consistent with the current Kit Of Parts. Atthe same time the Project Definition drawings included in Amendment #4 do notseem to address revisions to the station entrance plazas consistent with the newDirective Drawings. How should we proceed? Are we to follow thedefinition drawings or the Directive Drawings?

Proposal is to reflect the scope of work as shown in the Project Definition Drawings. 03.04.13

312 12.02.13 The current proposal due date provides insufficient time to adequaltely review themost recent amendment, initiate and develop design requirements, and competitivelyprice a project of this magnitude without considering and including significantcontingency. Given the magnitude and importance of the Westside SubwayExtension Project, we respectfully request a minimum six (6) week postponement ofthe current proposal due date of January 3, 2014.


12.05.13310 11.26.13 Regarding the Site Specific Environmental we have the following questions:1. A fifteen year policy term is not commercially available. The longest available termis ten years. Please advise.2. What type of due diligence will be performed?3. When will it be performed?4. If it has already been performed, can carriers be provided with the reports?5. It is interpreted that the Environmental Indemnification in the General Conditions ofthe RFP to limiting the Project Team’s liability to those environmental conditionswhich they create or exacerbate associated with their work. Why the LACMTA isrequiring the Contractor to secure a policy on their behalf when LACMTA is retainingthis liability and also paying for the policy via a change order?6. The extent of coverage available from the marketplace will be dependent on thequality and extent of the environmental documents provided by LACMTA. If theinformation is not thorough or if there is widespread contamination, some of therequirements may not be commercially available. Please advise.

313 12.02.13 The Good Faith Effort advertisement requirment is 21 days prior to the bid due date,requiring advertisiment in three publications soliciting DBE quotes. That 21daywindow now occurs between December 13, 2013 and Jan. 3, 2014, severelyhindering our ability to outreach with DBE firms and follow-up due to the holidays,and their ability to respond. Consequently, we respectfully request that the January3, 2014 date be extended a minimum of six (6) weeks to February 13, 2014, as wehave previously requested.


314 12.02.13 Amendments No.3 and No.4 have also greatly impacted our design engineringstudies, requiring a lot of revisions to work that had been finished. Accordindly, wesuggest that it is appropiate to increase the stipend amount forseen in the RFP, andrespectfulllu request that LACMTA increade the stipend to $2,500,000.

Stipend limits were established by LACMTA Board. 12.05.13

315 12.03.13 Referring to Technical Requirement 21 00 00 Fire Protection Systems, isolationvalves shall be installated at every other crosspassage, but no farther apart than1600 feet.

Although NFPA 130 is not referenced in this section, it seems to be the appropriatestandard. In NFPA 130, Clause 6.5.2.1.2, isolation valves shall not be more than800 feet apart.

Please kindly confirm if we should follow the Technical Requirements.

The Proposal is to include the cost of, and is to be in compliance with, NFPA 130,Clause 6.5.2.1.2.

AnswerQuestion

Refer to previous Question No. 240. The solution adopted by LACMTA inAmendment No. 4 only deleted the reference to Class II landfills in GeneralRequirements Section 01 35 43 3.04.E and Bid Item 46, but did not resolve the issuethat presents a risk of millions of dollars. According to the largest operator of landfillsin this area, the various Regional Water Quality Control Boards that ultimately governand permit the landfills in this area are not willing to commit at this time to letting thelandfills accept “Naturally Occurring Tar Sands”. This issue could cause all the tarcontaminated material to either be hauled to the central valley landfills or out of state,but the Proposers cannot determine that at this time. We request that LACMTAestablish separate Bid Items, similar to Bid Item 46, for the incremental costsassociated with disposal of contaminated soils at Class I landfills, Class II landfills,Class III landfills, and Subtitle D landfills in order to reduce the cost of risk that wouldotherwise be put into the Price Proposals.

As an alternative, please provide a bid basis to estimate how much excavatedmaterial will go to a Class II versus a Class III landfill.

318 12.03.13 Has a wheel/rail interface or similar/vehicle track interface study been undertaken forthe existing system and, if so, can it be made available?

A wheel/rail interface or similar vehicle/track interface study is not available. 12.10.13

319 12.03.13 Please confirm the make/manufacturer of the standard Direct Fixation Fasteners forthe existing system and what alternatives, such as LVT (low vibration track) orfloating slab track, are used elsewhere on the system.

Metro currently procures direct fixation replacement fasteners from L. B. Foster orAmsted RPS. Metro has not procured any replacement Type 3 (egg) fasteners.Metro has not procured any replacement Resiliently Supported Block Ties (RSBT) ofLow Vibration Track (LVT) used on the Metro Gold Line Eastside Extension (lightrail) originally provided by The Permanent Way Corp. Please note that theContractor is to design and submit for approval all track materials regardless ofprevious Metro use or approval.

12.10.13

320 12.03.13 Please confirm if it is planned to operate more than one type of rail vehicle in normalservice and what specific vehicles they will be.

Metro plans to operate more than 1 type of rail vehicle during normal service. Thoseplanned vehicles are: A650 base buy, A650 option cars and a forthcomingprocurement.

12.10.13

321 12.03.13 Amendment 4, Division 1 Section 01 11 01, Article 3.02 D. 2 states that a soldier pilesystem is allowable at the Wilshire/Fairfax Station if shotcrete lagging is installed asthe excavation is advanced. However, Article 3.02 B. 1. a) 1 states that the followingexception should be made to Metro Rail Structural Standard Drawing SS-002: “DoNot Use 'Semi-rigid wall systems include tangent or secant pile wall or similarsystems.'” Is the word "include" meant to be "including"? Does this clause mean thattangent and secant pile walls are not allowed for excavation support on any of thestations? How is “semi-rigid” and "similar systems" defined in Article 3.02 B. 1. a) 1?Please confirm the type of excavation support systems that will be allowed at thestations.

Amendment 3, Division 1 Section 01 11 01 Article 3.02 B 1 a 1 states not to use thenote regarding design of semi rigid wall system on Structural Standard Drawing SS-002. The tangent pile and secant pile wall systems maybe be used. The lateralpressure diagrams are for flexible and rigid wall systems only. Tangent pile wallsystem would fall under flexible wall system while secant pile wall system would fallunder rigid wall system.

AnswerQuestion

322 12.03.13 According to Section 2, Clause SP-58 / SP-58 A., it seems that there is no cap onContractor's liability to the LACMTA for costs incurred by LACMTA, itsrepresentatives and contractors in completing or correcting the work. Werespectfully request your consideration of the fact that the completion costs for aproject this size could be very large, thereby substantially reducing the total limit onliability. We respectfully propose that SP-58 reads: “The Contractor’s Liability to theLACMTA for damages arising out of its performance of the Contract (or failure toperform hereunder) shall be limited to the sum of the following: A) all [40% of] costsreasonably incurred by LACMTA, its representatives or contractors in completing orcorrecting the Work…”

323 12.03.13 In the event of termination for convenience or default, the Contractor shall givewaiver of consequential damages towards LACMTA under Section 2, Clauses GC-37.6 and GC-38.7. But, it doesn't seem that there is any clause specifyingLACMTA's waiver of consequential damages towards the Contractor. We would liketo respectfully suggest adding the following language: “No Party shall be liable to theother Party for loss of business reputation, loss of opportunity, loss of revenue, lossof profit, loss of any contract, cost of capital or for any indirect, incidental, special orconsequential loss or damage which may be suffered by the other Party inconnection with this Contract.”

324 12.03.13 Article 3.01 B. 3 states that construction photographs shall be taken monthly. Article3.01 C. states that no less than 100 photographs shall be submitted each week.Article 3.01 D. states that progress photos shall be submitted monthly with thenumber of photos adequately depicting the construction activities. Please confirmhow often and how many construction photos are required to be submitted.

Regarding the requirement for monthly construction photos (only); the Contractor isto submit construction photographs monthly. The number of photos submitted are toadequately depict the construction activities. As construction activities ramp up andconstruction is occurring at multiple locations the number of photos needed tocomply with the requirement to adequately depict the construction activities will needto increase.

12.13.13

325 12.03.13 Structural Standard Drawing SD-011 shows part of the suggested connection detailbetween the bored tunnel and the station. In Note 3 it states: "Installation of seal …for detail see the Tunnel Directive Drawings". We cannot find a directive drawingthat shows the connection between a segmental lining and station end wall. Can therelevant drawing be supplied?

The question refers to drawing SD-11 as “Structural Standard Drawing”, however it isa Structural Directive Drawing. Structural Directive Drawings are provided forguidance to the Contractor and may not meet all the Contract requirements. TheContract requirement is as follows from Technical Requirement Section 07 10 00,Water and Gas Protection Systems, Section 2.01 A.4.b: Tunnel to Station andTunnel to Crosspassage Interface – As a minimum provide the following: 1) A doublesealed connection capable of rotational and translational movement of sufficientmagnitude to accommodate the combined effects of differential non-seismic andseismic movement between the two structures. Design the connection to permitfuture injection sealing behind the structures that is readily accessible from within thestation or tunnel should a leak occur, together with the replacement of the secondaryseal. Both primary and secondary seals are to allow joint movement in combinationwith water pressure.

326 12.03.13 Paragraphs F.2 and F.3 of Article 01 71 43 1.08 indiacte that no work will be allowedduring holiday periods. We assume that "no work" is defined as "no work withinpublic right of way that could require lane closures or create obstructions to vehicularor pedestrian traffic." Please confirm.

During the week of Thanksgiving and the week between Christmas and New Years(in the City of LA) and during the City of Beverly Hills holidays listed in Section 01 7143 generally no work at or above grade within the public right of way is allowed.Work beneath the decking system (which is within the public right of way) will beallowed. However, it should be noted that the Contractor may be allowed to performsome at grade work within the public right of way within these periods provided theyare working with an approved Traffic Control Plan (TCP) / Traffic Management Plan(TMP) and have obtained a Holiday Moratorium Exemption. An example of thiswould be work in the public right of way that is behind the K-Rail. Contractor will berequired to work with both cities each holiday season to determine specificrequirements and specific days of work during the week of Thanksgiving and theweek between Christmas and New Years.

327 12.03.13 2.01.E of Section 01 52 13 says that Metro offices are to be designed for floor load of100 psf, while 2.01.G indicates 125 psf. Please confirm which is correct.

Proposal is to reflect the cost to comply with Section 01 52 13, 2.01.E, which statesthat Metro offices are to be designed for floor load of 100 psf.

12.10.13

328 12.03.13 Article 2.02.B of Section 01 52 13 indicates that the Design-Builder is to provide twooffices, presumably for LACMTA, in its Construction Management offices, along withtwo desktop computers. Article 2.01.D indicates that Metro would provide desktopcomputers for its staff. Since the Design-Builder will provide office trailers forLACMTA adjacent to its own offices at each site, would you clarify the intent of Article2.02.B?

As the location of the Contractor’s Design Office and the Contractor’s ConstructionField Office or single Construction Management Office is unknown at this timerelative to the proximity to the planned Metro Construction Field Office, theContractor is to provide 2 offices in the Design Office and in the Construction FieldOffice or in the single Construction Management Office for Metro’s use. TheContractor is to provide 2 desktop computers with internet access and phones forMetro use.

330 12.03.13 The evaluation criteria for Delay Compensation Prices refers to Schedule E. Weassume that this should refer to Schedule D. Please confirm.

Yes, the reference will be corrected to reflect Schedule D. 12.13.13

331 12.09.13 As we have previously explained in prior communications, with the extent of thechanges made by LACMTA to the RFP documents to date, the 21-day DBEnotification requirements over the holiday season, the schedule delays to the AURcontracts, and the price risk involved in many of the answers to the questions orunanswered questions (specifically question nos. 240, 279, and 371), the currentProposal Submittal daye of January 3, 2014 is at this point unrealistic.

332 12.11.13 This is in follow up to Q&A 286 response. There are current NFPA 130 and/or MetroRail Design Criteria (MRDC) requirements as to the nature of Emergency VentilationSystem (EVS) equipment. One example of many, according to NFPA 130 7.3.1.1, istheir ability to 'achieve their full operating speed in no more than 30 seconds from astopped position'. As noted by Metro, should the PLE Design Build contractordetermine the capacity (air volume) for use on the PLE project, is the EVS equipmentrequired to be upgraded to current NFPA 130 and/or MRDC requirements?According to NFPA 130 paragraph 1.3.1, and except for the SCADA interfacesalready noted, we believe no such further equipmentupgrades are required. Please confirm our understanding is correct.

333 12.11.13 Reference Section 34 11 16B, part 1.01.B: This paragraph says "thermite welds arenot allowed in the tunnels for this project": If the Trackwork Contractor does not startwork until after the tunnel and invert are complete and the tunnel is sealed at thattime, will thermite welds be allowed? Thermite welds are an industry wide applicationfor connecting CWR strings and are equivalent to in track welds.
