Questions and Responses

Ql. In the prequel in Criteria part 5 - Financial & Project Surety, you request a letter from our insurancecarrier / agent that the Contractor can meet the limits required in "Attachment 4" 1 do not see anattachment 4 and the only insurance limits I see are in Attachment 5. Please advise if there is anattachment 4, and if there are additional insurance requirements not included in attachment 5.

Al. See Addendum No. 2

Q2. Section XIX of the contract states "The decision of the Assistant General Manager of Procurement,Supply Chain & DBE shall be binding upon the Contractor and SEPTA." It is highly unusual for apublic contract to not provide the Contractor with an ability to appeal the owner's decision on adispute to a court of competent Jurisdiction. Will SEPTA amend this clause to allow Contractor sucha right to an equitable dispute resolution process?

A2. See Contract, XIV.H and XVIII

Q3. (meetings) It is typical on design build projects of this nature with Govemment entities to allowconfidential one-on-one meetings with proposers to discuss technical alternatives and other issues. Thisallows the proposer to coordinate closely with the client and has proven to be extremely effective for boththe client and proposer in preparing compliant bids. Will SEPTA amend the contract documents to allowone-on-one meetings?

A3. Per Instructions; ^^Step One will consist of the request for, submission, evaluation, and (ifdeemed necessary by SEPTA) discussion of the RFQ Proposal."

Q4. Refer to section XII.C - 4th paragraph. This paragraph appears to allow SEPTA to withhold ALLpayment for ANY default, regardless of how minor. Please revise the language to allow SEPTA towithhold payment only to the extent necessary to protect SEPTA from subject default. Proposedmodification: In the first sentence of the subject paragraph replace "shall not be obligated to make" with"may withhold" and insert "to the extent reasonably necessary to protect SEPTA from said conditions"after the word "exists".

A4. See Addendum No. 4.

Q5. Refer to Section VIII.G - Indemnification. The following modifications are proposed to thereferenced indemnity clause: In the first paragraph delete "release and be liable for and to" and delete"consequential damages," and delete "whether or not" In the third paragraph delete "be liable for and to"

AS. See Addendum No. 4.

Q6. Refer to Section XIV.H - Prior Notice Required as Express Condition of any Claims for AdditionalCost. Proposed modifications: Replace the last sentence of the first paragraph with "The Contractorexpressly agrees that it shall not make any claim, nor be entitled to any additional cost, against SEPTA tothe extent resulting from the actions of any Subcontractor on the Project it being clearly understood thatthe Contractor's sole avenue of recovery is against such Subcontractor."

A6. Contract remains unchanged.

Addendum No. 4

Q7. Refer to Section XVIIl.N - Overhead Obstacles. Proposed modifications: Replace "No adjustments tothe Contract price or completion date will be granted based on the Contractor's failure to provide for anyoverhead obstacle in the prosecution of the Work." with "No adjustments to the Contract price orcompletion date will be granted based on the Contractor's failure to provide for any overhead obstaclewhich was reasonably discoverable prior to bid in the prosecution of the Work"

A7. See Addendum No. 4.

Q8. Please extend the RFI due date from 9/15/17 to 9/21/17

A8. See Addendum No. 3

Q9. Refer to Section 01010-14 - Milestone table. At this stage in the process, it is not possible todetermine the achievability of the interim milestones. We suggest that SEPTA allow the proposer todefine these interim milestone dates with the final proposed schedule. Note, final completion date canremain unchanged.

A9. The RFP requires that the DB contracting teams provide a Technical Proposal (TP), a portionof which will include providing a milestone/construction schedule that indicates the durations thatthe DB team anticipates in performing the various work scope items/tasks at each location.

QIO. What is the anticipated duration between release of the Step 2 Invitation to Bid documents andsubmission of the price proposal? We request a minimum of 8 weeks.

AlO. SEPTA anticipates two (2) weeks from Step 2 Invitation to Bid (Price Proposal) beingreleased.

Qll. What is the bid date for step 2?

All. See response to QIO.

Q12. The last paragraph of page 12 of the Request for Qualifications document states that SEPTA hasalready purchased the (5) Autotransformers. However according the 01010 (Summary of Work) page 5,18.d there are (6) Autotransformers, two per site. Please confirm whether there are (5) or (6) and thatSEPTA is furnishing all Autotransformers.

A12. There will be six (6) autotransformers supplied by SEPTA for this project; two (2) at eachTPSS site.

Q13. (ATC) It is typical on design build projects of this nature with Government entities to allowproposers to submit confidential technical alternatives or approaches for approval pre-bid. This willbenefit both SEPTA and the proposer. When approved these usually result in a reduction in bid price,improvement in schedule, improvement in quality, and/or some other benefit to SEPTA, which allows theproposer to be more competitive. Will SEPTA amend the contract documents to allow submission ofconfidential Alternative Technical Concepts (ATC) for approval pre-bid?

A13. See response to Q3.

Q14. (Property) Please confirm that SEPTA owns all property needed for the contract and if not willacquire it or otherwise obtain access for the proposer. See drawing C20I, Note 4 for an example.

Addendum No. 4

A14. The property required to upgrade each of these 3 TPSSs is all presently owned by SEPTA.However, any other property (s) near the sites that may be needed to stage/storeequipment/materials will be the responsibility of the Contractor. This includes the wooded parceladjacent to Neshaminy TPSS (north side) that SEPTA forces will clear and make horizontal for theContractor to then finish as he sees fit to use for delivery/storage and activities.

Q15.Specification 01010, Table 01010-2, defines the final design milestone to be completed 6 monthsafter NTP, with permitting to be completed 8 months after NTP. However, drawing G110 shows thedevelopment of the final design to take place over the full project duration. Please clarify if theContractor may propose a different milestone schedule for the design of the substations, which follows amore staggered approach as the substation construction completion periods.

A15. Specification Section 01010 specifies target milestone durations. Drawing GllO describes asuggested staging sequence. The Contractor shall consider this information while developing amilestone schedule that accommodates the Contractor's means and methods.

Q16. Please confirm that SEPTA will supply all 50% design drawings in AutoCAD electronic format andall 50% specifications in Microsoft Word electronic format for the final designer's use.

A16. SEPTA will provide all 50% drawings in AutoCAD electronic format and all 50%specifications in Microsoft Word electronic format. These electronic format documents will beprovided to the selected Contractor only.

Q17. Please clarify whether the 10ft working clearance to live electrical parts stated in Specification01065 1.05.H.1.C and on drawing GI04 Note 24 can be reduced based on the Final Designer'sinterpretation of IEEE and OSHA allowable working clearances.

A17. When doing work with NO SEPTA support, 10 foot working clearance can be reduced ifallowed by and meets lEEE/ANSI/OSHA requirements.

Q18. We request that the RFI submittal period is extended 14 calendar days.


Q19. We request that the RFQ Step 1 period is extended 30 calendar days due to the amount of materialsrequired to be provided.

A19. See Addendum No. 4. SEPTA is extending proposal due date to 10/18/17 for the Step OneTechnical Proposal due date.

Q20. We request that the Bidder be given 60 calendar days to prepare a final bid after receivingnotification that they have been requested to submit a bid.

A20. No.

Q2I. Please clarify where the Contract design and construction scope ends with respect to the two new12 kV feeders at Yardley. Dwg G108 shows one line extending south of sectionalizing switch YA2 andthe other at West Trenton Yard.

A21. Contract scope ends at the trackside gantry structure - the feeders from the trackside gantryto West Trenton Yard are not in this contract scope.

Addendum No. 4

Q22. Please confirm that the sketches on GllO are proposed plans, not existing plans.

A22. Sketches shown on GllO depict suggested staging plans.

Q23. Drawing GllO states that site work at Bethayres may be started with SEPTA approval, while finaldesign of other substations is in progress. Please confirm that final design for the second and thirdsubstations may continue beyond the 6 month milestone shown in Specification 01010, Table 01010-2.


Q24. Specification 01010 l.Ol.F states, "The Contract is intended to rehabilitate the substations to a likenew state. All equipment, components, installations, SCADA, lighting, auxiliary power systems,conductors, and cables, unless expressly stated otherwise, shall be replaced. The only exceptions are thecontrol house building and the outdoor steel structure which shall be repaired, cleaned, primed andrepainted to a like new state." However, Neshaminy drawing E201 shows "NIC" for the 100 Hz signalpower panel, 480 V switchgear, signal power 4.2 kV control panel, and M-A set. Please clarify if thesignal power equipment is not-in-contract and not to be rehabilitated as part of this project scope. Also,please confirm that the Neshaminy 100 Hz transformers are not-in-contract - they are not marked "NIC"on drawing E201.

A24. Neshaminy Signal power equipment is not part of this contracts work scope and the HZtransformers are also not in contract. There is traction power equipment - such as the new RTU towhich the signal points will be transferred - that is located in the signal power room and IS in thescope of this contract.

Q25. Please confirm that the Neshaminy Halon fire suppression system shall be removed, but notreplaced with another type of fire suppression system.

A25. The Halon fire suppression system will be removed, and not replaced with any other firesuppression system.

Q26. On drawings TP106, TP206, and TP306, please clarify the intent of these clearances. Somereferences are applicable for clearances between conductors (NESC 235-1), while other clearances are forsafety from live parts to any permanent supporting surface for workers (NESC 441-1). Are theseintended to be safety clearances for protecting personnel or for installing permanent equipment?

A26. The clearances on Drawings TP106/206/306 are for installation of permanent equipment. Theclearances for live part to fence and vertical clearance to ground are for personnel safety.

Q27. Contract section XI.C.l states that the Contractor cannot make any claims for increased costs,charges, expenses or damages against SEPTA for any delays or hindrances experienced in theperformance of the Work, whether caused by any act or omission of SEPTA or from any causewhatsoever. This does not seem reasonable, due to the fact that this work is being performed on an activerailroad. The contractual schedule is based on obtaining substation outages when needed. If outage timesare denied or cut short, this impacts the schedule and costs. Also, major equipment is being supplied bySEPTA, which can affect the schedule due to failed factory tests or other deliveiy delays, such as damageduring shipping. Contractor working times can be affected by shortages in SEPTA safetypersonnel. Will SEPTA amend the Contract to allow change orders for schedule and costs associatedwith delays caused by SEPTA?

A70. Yes.

Q71. 16791 & 16290 - Is the requirement for an HMI for local control and indication necessary?Previously, these have been provided for substation locations with indoor switchgear to provide a safeplace for substation maintainers to operate breakers (away from potential arc flash hazards). Since thecontrol panel is inside and all breakers are outdoor, the control panel itself becomes the HMI with controlswitches, indicating lights and panel meters. A simple monitor, keyboard and mouse can be provided toaccess the gateway for status and troubleshooting.

A71. Yes, an HMI is required. Contractor will also be required to load station drawings to theseHMIs.

Q72. 16792 & 16290- If HMI is to be provided, please indicate location where it is to be connected.System / site block diagrams (TP 120 for example) do not show the connection / location of the HMI.

All. The HMI will be mounted on the RTU and connected to the LAN network.

Q73. 16793 & 16290 - If HMI is required, please indicate required size and location of the unit. Thereare conflicting directions in the specification on physical location of the HMI (control panel vs RTUcabinet). There is likely not enough room in the control panels (as shown) to install an HMI screen. Isthe HMI to be "touch-screen" or provided with keyboard & mouse? NOTE - RTU is located in a differentroom from the control panels at Neshaminy.

A73. See answer to A88. The HMI will be provided on the RTU door, and should be touch-screentype. At Neshaminy, the preliminary design locates the RTU in a different room (the Contractorshall explore the feasibility of locating it in the control room).

Q74. 16794 & 16290 Please confirm communication protocols between Bay Modules, Relays &Gateway to be 1EC61850 and Communication protocol between Gateway & RTU to be DNP3.0.

A74. Yes, this is correct.

Q75. 16795 & 16290 - There is only one gateway module shown on the block diagrams. Pleaseconfirm that the gateway is not to be redundant.

A75. There will be one gateway.

Q76. Drawing TP 121, TP221, TP321 Drawing(s) state that the point chart is preliminary and that thecontractor shall develop the final point listing to address the requirements of the new equipment. It isnoted that several points that have been required and/or added on previous projects are not listed on thesesheets. These include, but are not limited to the local, remote and relay operation of the circuit breakers.

Addition of these (and other) points at a later date can cause confusion, leave potential gaps inprograming and create additional costs to the contractor. It is imperative that SEPTA list ALL OWNERREQUIRED status, analog & control points at this juncture so that the SCADA & network equipment canbe priced and bid accordingly.

A76. It is the responsibility of the Contractor to develop the point assignment chart with the help ofSEPTA. This will take place very early in the project after NT? and have a defined cut-off date forthe FINAL point chart. The point chart for Jenkintown TPSS is provided as a reference documentfor this guidance.

Q77. Reference attachment Drawing 1VSR630254C0001 included with attachment 4 indicates thatcross beam and fixing parts for the single pole ABB breakers is included in the scope of supply(equipment provided by SEPTA). Contract drawings indicate that new steel is to be provided by theContractor. Please clarify. Also, there appears to be some type of vertical mast or arm for mounting thecontrol box for the breakers (this is also shown in the contract drawings but not detailed). Is this providedwith the equipment supplied by SEPTA or is the contractor to include this as well? Please providedetails. Also, please confirm that SEPTA will be supplying vertical supports for the 2 Pole Breakers andthat the details of these supports are the same as shown on drawing 1VSR630253C001 in the sameattachment.

A77. Reference documents have no contractual basis for design or construction.

Except for the 2-pole breakers, all new steel will be provided by the Contractor. The vertical beam

(mast or arm) for mounting the control box shall be supplied by the Contractor. Vertical supportsfor the 2-pole breakers are supplied by SEPTA with the breakers. The Contractor shall provide all

other structural steel and mounting hardware, such as for grounding & bonding and attachments

for control cables. Addendum No. 5 will have revised drawings S106,8207,8208,306 & 8307.

Q78. Site Visit - we would like to request a site visit to SEPTA's Ambler Substation. It was stated at theprequalification meeting that the exact equipment to be provided by SEPTA is installed at this location. Itwould benefit the contractors to see the equipment installation to help develop the understanding ofhandling and installing.

A78. Visit to the substation will be scheduled at a future date.

Q79. 01380.3.01.G - Specification requires photos of traction power equipment during stages ofmanufacture. SEPTA is providing major traction power equipment (Circuit Breakers &Autotransformers). Please advise if this section is applicable to this contract.

A79. This clause is applicable since the Contractor will be purchasing other electrical equipment(trolley breakers, for example) than the SEPTA-provided equipment.

Q80. 16772.2.04 Specification requires "Genetic Pro" base software and licenses. Will "as equal"such as "Hikvision" be acceptable? "Hikvision" has been specified for other SEPTA projects.

A80. "Hikvision" is acceptable to SEPTA.

Q81. What is the completion schedule for the work currently being performed at Yardley Station. Thecontractor there is currently occupying the access and staging areas allotted for this project. Time line ofcompletion ofcurrent work could affect schedule and approach for the substation rehabilitation.

Addendum No. 4

Q90. 01010.1.06.1.a.5.a - Specification says to "coordinate with SEPTA to jumper the section switch ontrack 1 to maintain continuity of catenary power during outage". Will SEPTA install this Jumper or willthe contractor be responsible? This will tie the trolley feeds from Jenkintown (JIB) to Neshaminy (NIB).Does SEPTA foresee any temporary changes to the protection settings at the outlying substations toaccommodate for the extended reach of the circuit? Will SEPTA make relay settings changes or will thisbe the responsibility of the contractor. NOTE - Same situation / question is applicable to all locations andstages.

A90. The Contractor will install the jumpers - SEPTA will not change any relay settings at theexisting substations. If required at the new installations, the Contractor will then make theseadjustments. The Contractor will also need to perform and submit proposed relay settingcalculations for SEPTA's approval prior to implementation. In addition, a SEPTA relay technicianwill need to be with the Contractor when any relay setting revisions are made both at theinstallation of the jumper and the removal of the jumper. All electronic relay files before and afterthe installation of the jumper will need to be saved by the Contractor.

Q91. Will existing survey information and electronic survey files be provided to DB Contractor Team?

A91. Any survey that the Reading Company did 90 years ago and that is still available will be

provided to the selected Contractor after NTP.

that has the potential to foul, and/or working within 10 feet of railroad tracks shall attend a SEPTA

safety seminar full day class on safety rules and operating procedures (SRW Course)." Please clarify

whether personnel working at Bethayres, Neshaminy Falls, and Yardley Substations need Roadway

Worker Protection (RWP) Training if their activities are confined to work that is 10 feet away from

railroad tracks, or if they are crossing the tracks at Neshaminy Falls under SEPTA's direction.


Q97. If RWPtraining is required for all personnel working at Bethayres, Neshaminy Falls, and Yardley

Substations before accessing sites, will special training classes be made available for the Contractor and

his Subcontractors to maintain their proposed construction schedule, or will the Contractor and

Subcontractors need to wait for the next class to become available, regardless of project schedule

delay?

A97. There will be an effort made by SEPTA to establish special training classes for thecontractor's staff.

Q98. May the Design Manager and the Traction Power Lead Engineer staff positions, described in

specification 01010 1.03.H.2 and 1.03.H.4, be served by the same individual, provided that the individual

meets all qualifications of both positions?
