Engineering Staff (Staff) conducted interviews with the two lowest bidders on August 16, 2012.·.During Staff's investigation of the two lowest bidders (Villalobos and Silva), Staff determined thatVillalobos' submitted the most responsive bid and will serve the best interest ofthe County for thespecific project. Silva Construction has not had any experience working on a major arterial likeQuebec, Lincoln and University. Silva has not had any experience with Class E concrete. Silva hasvery little experience with panel replacement. Although Silva had great references for theirwork oncurb, gutter, sidewalk and curb ramps, the construction phasing and work required for this project ismore complex, and, Silva lacks the experience needed for this project.

Villalobos has completed the last three years ofconcrete repair on the arterial ofHigblands Ranch and. has the reql!ired experience on an phases bfthis project. Villalobos recetitlywon a local paviIi.g award

for their work in Douglas County, and our Engineering Inspection Staffbelieves that Villalobos is bestsuited to perform the work required for this project.

Staff recommends approval of a construction contrac;:t to Villalobos Concrete, Inc. in the amount ofOne Million Forty Two Thousand Eight Hundred Sixty Six Dollars and Thirty Five Cents($1,042,866.35). ·Funds for this project are set aside in Fund 230, Account No. 800851.

REVISION OF SECTION 103 AWARD AND EXECUTION OF CONTRACT

Section 103 of the Standard Specifications is hereby revised as follows: 103.01 CONSIDERATION OF PROPOSALS Subsection 103.01 shall include the following: Douglas County reserves the right to consider any Bidder as unqualified to perform the Contract who does not consistently perform with his own forces a major portion of the work involved in the construction of the improvements. "Major portion" is interpreted to mean at least thirty percent (30%) of the total cost of the Contract. 103.02 AWARD OF CONTRACT Subsection 103.02 is amended to read as follows: The Contract, if awarded, shall be executed within 60 calendar days after the opening of Bid Proposals unless both the successful Bidder and the County both agree in writing to allow additional time. The Contract will be awarded to the lowest responsive, responsible Bidder who will serve the best interests of the Owner; and the Owner reserves the right to make this determination. The County, however, reserves the right to reject any and all Bids and to waive informality or technicality in any bid, and to disregard all non-conforming, non-responsive Conditional or Alternate Bids whenever such rejection or waiver is in the County’s best interest. The successful Bidder will be notified at the earliest possible date, by telephone, fax or letter mailed to the address shown on their Proposal that their Bid has been reviewed and Douglas County Engineering will be recommending to the Board of County Commissioners award of the Contract. If the Board of County Commissioners approves the Conditional Notice of Award, then the Contractor will be given notice, which will need to be acknowledged by the Contractor. In determining whether the low bid is from a "responsive and responsible Bidder," the following criteria will be considered:

a. Whether the Bidder has received prequalification status (active status) with the Colorado Department of Transportation for bidding on contracts of a similar size and type;

b. The Bidder's financial responsibility;

SSP-5


REVISION OF SECTION 103 AWARD AND EXECUTION OF CONTRACT

- continued -

c. The Bidder's previous performance (both satisfactory and unsatisfactory) on completing prior Douglas County contracts, including performance of any required warranty repair work;

governmental agencies. 103.04 EXECUTION AND APPROVAL OF CONTRACT Subsection 103.04 is amended to read as follows: The Agreement shall be signed by the successful Bidder and returned, together with the contract Payment and Performance Bonds, Certificate of Insurance and all other formal contract documents, within ten (10) days after the date of Conditional Notice of Award. If the successful Bidder returns the signed Agreement and has submitted acceptable Payment and Performance Bonds, Insurance Certificates and all other formal contract documents within ten (10) days after the date of Conditional Notice of Award; then if the Agreement is not executed by Douglas County within thirty (30) days from the date of the Conditional Notice of Award, then the Bidder shall have the right to withdraw the Bid Proposal without penalty. The Notice to Proceed process may be accelerated; and provided both parties agree to the Contractor submitting applicable Payment and Performance Bonds, Certificate of Insurance and all other formal Contract Documents prior to the receipt of the Conditional Notice of Award. This will allow the Board of County Commissioners (BOCC) and the Contractor to fully execute the Agreement at the same time the BOCC would grant the Conditional Notice of Award. No Agreement shall be considered effective until it has been fully executed by all the parties thereto.

SSP-6


REVISION OF SECTION 104 SCOPE OF WORK

Section 104 of the Standard Specifications is hereby revised as follows: 104.02 DIFFERING SITE CONDITIONS, SUSPENSIONS OF WORK, AND

SIGNIFICANT CHANGES IN THE CHARACTER OF WORK Subsection 104.02(a) shall include the following: The County assumes no responsibility for the condition of existing streets and structures and other property in the project area nor for their continuance in the condition existing at the time of issuance of the INVITATION FOR BIDS or thereafter. No adjustment of Contract Price or allowance for any change in conditions, which may occur after the INVITATION FOR BIDS has been issued, will be made. Subsection 104.02(c) is amended to include the following: Unless such alterations and increases or decreases materially change the character of the work to be performed or the cost thereof, the altered work shall be paid for at the same unit prices as other parts of the work. If, however, the character of the work or the unit costs thereof are materially changed, an allowance shall be made on such basis as may have been agreed to in advance of the performance of the work, or in case no such basis has been previously agreed upon, then an allowance shall be made, either for or against the Contractor, in such amount as the Engineer may determine to be fair and equitable. Material change of the character of the work to be performed or the cost thereof as used herein means an increase or decrease in quantities over or under the plan quantities amounting to an aggregate increase or decrease to the original Total Contract Amount of twenty-five percent (25%) or more. The Unit Price or Lump Sum Price for each of the listed items in the Bid Proposal of each Bidder shall include its prorated share of overhead so that the sum of the products obtained by multiplying the quantity shown for each item by the unit price bid represents the total Bid. The special attention of all Bidders is called to this provision, for should conditions make it necessary to revise the quantities, no limit will be fixed for such increased or decreased quantities. No adjustment to unit prices will be allowed, provided the net monetary value of all such additive and subtractive changes in quantities of such items of work (i.e., difference in cost) does not increase or decrease the original Total Contract Amount by more than twenty-five percent (25%). The County may make changes in the scope of the work required to be performed by the Contractor under this Contract by making additions thereto, or by omitting work therefrom, without invalidating the Contract, and without relieving or releasing the Contractor from any of his/her obligations under the Contract or any guarantee given by the Contractor pursuant to the Contract provisions, and without affecting the validity of the guaranty bonds, provided that the total net amount of the changes do not change the original Total Contract Amount by more than twenty-five percent (25%). All such work shall be executed under the terms of the original Contract unless it is expressly provided otherwise.

SSP-7



- continued - Except for the purpose of affording protection against any emergency endangering life or property, the Contractor shall make no changes in the work authorized under this contract unless in pursuance of a written order from Douglas County authorizing the change. No claim for an adjustment of the Contract Price will be valid unless so ordered. If applicable unit prices are contained in the Contract (established as a result of a unit price bid), the County may order the Contractor to proceed with desired changes in the work, the value of such changes to be determined by the measured quantities involved and the applicable unit prices specified in the Contract. If applicable unit prices are not contained in the Contract, or if the total net change increases or decreases the original Total Contract Amount more than twenty-five percent (25%), the County shall, before ordering the Contractor to proceed with desired changes, request an itemized proposal from him/her covering the work involved in the change, after which the procedure shall be as follows: If the proposal is acceptable, the County will prepare a change order in accordance therewith

for acceptance by the Contractor. Each change order shall include in its final form: (1) A detailed description of the change in the work, (2) The Contractor's proposal (if any) or a confirmed copy thereof, (3) A definite statement as to the resulting change in the Contract Price and/or Time, (4) The statement that all work involved in the change shall be performed in accordance with contract

Requirements except as modified by the change order. 104.04 MAINTAINING TRAFFIC Subsection 104.04 shall include the following: Before proceeding with construction, the Contractor will submit to the Engineer a detailed proposal in writing of his method of handling traffic during construction for review and approval. Depending on the circumstances, the Owner/Engineer may require more than ten (10) calendar days to review and approve the Contractor’s submittal; and the Contractor shall take this into consideration when planning their schedule for these submittals. It is the Contractor’s responsibility to adequately plan the submittal of all necessary traffic control plans in order for approval to be granted at least three (3) calendar days prior to construction and at least three (3) calendar days prior to a change in condition. During the course of construction, the Contractor shall provide a detailed traffic control plan, which shows how the Contractor will handle traffic for the various phase(s) of the scheduled construction work. Details in the plan will include, but not be limited to; hours of work in compliance with

SSP-8



- continued - project special provisions, placement of signs and barricades, use of traffic control devices such as cones, barriers, and barricades, stationing of flagging personnel, access control, temporary striping, maintenance of detours, dust abatement, and length of lane closure tapers. The Contractor will not be permitted to have construction equipment or materials in the lanes open to traffic at any time unless so directed by the Engineer. The Contractor shall remove and reset all construction signs prior to any adjacent construction. Any damaged signs shall be replaced in kind or repaired by the Contractor. The Contractor is cautioned that all personal vehicle and construction equipment parking is prohibited where it conflicts with safety access or the flow of traffic. The Contractor will be required to notify the County three (3) calendar days prior to the date the Contractor intends to start construction. During the various phase(s) of construction of this project, traffic will need to use the present traveled roadways, (unless noted otherwise in the plans or Douglas County Project Special Provisions). Temporary detours need to be submitted to the Engineer for review and approval. Measurement or payment will not be made for the costs associated with temporary detours unless specified otherwise in the plans or Project Special Provisions (PSPs). If the Contractor determines that additional temporary detours are advantageous across private property, then the Contractor is responsible for all costs associated with constructing and maintaining the detours and any additional costs to obtain the additional easements. The Contractor shall provide written proof of permission from private property owner(s) to the Engineer prior to scheduling work to commence on said private property. The Contractor shall be responsible for furnishing and maintaining all traffic control devices in accordance with the manual on Uniform Traffic Control Devices (MUTCD).

The traffic control supervisor and all flagging personnel shall be certified by the Colorado Department of Transportation before working on this project and shall maintain such certification throughout the project duration. The Contractor shall not be permitted to place emulsion or tack coat on any surface to be chipsealed, patched, or leveled where traffic will be forced to travel upon the fresh emulsion or tack coat. The Contractor shall inspect, maintain, and keep all traffic control devices clean throughout the project duration including during periods when other work required for the project has been suspended due to inclement weather, unless approved otherwise in writing by the Engineer.

Each request shall be in writing and shall list the various items and the latest date by which each will be required by the Contractor. The first list shall be submitted within two weeks after Contract award and shall be as complete as possible at that time. The Contractor shall, if requested, furnish promptly any assistance and information the Engineer may require in responding to these requests of the Contractor. The Contractor shall be fully responsible for any delay in his work or to others arising from his failure to comply fully with the provision of this paragraph. 105.11 COOPERATION BETWEEN CONTRACTORS Subsection 105.11 shall include the following: If, through acts or neglect on the part of the Contractor, any other contractor, individual, or any subcontractor shall suffer loss or damage on the work, the Contractor shall settle with such other contractor, individual or subcontractor by agreement or arbitration, if such other contractor, individual or subcontractor will so settle. If such other contractor, individual or subcontractor shall assert any claim against Douglas County on account of any damage alleged to have been so sustained, the County will notify the Contractor who shall defend at his own expense any suit based upon such claim; and if any judgment or claims against the County shall be allowed, the Contractor shall pay or satisfy such judgment or claim and shall pay all costs, expenses, and attorney’s fees in connection therewith, and

SSP-11

The Engineer shall have the right to reject defective material and workmanship or require its correction. Unacceptable workmanship shall be satisfactorily corrected.

SSP-12



- continued - Rejected material shall be promptly segregated and removed from the Project, and replaced with acceptable material.

The Contractor shall furnish promptly all materials reasonably necessary for any tests, which may be required. All tests by the County will be performed in such a manner as not to delay the work unnecessarily and shall be made as provided in the Standard Specifications or these special provisions. The Contractor shall submit all material or equipment certificates, affidavits, etc., as called for in the Standard Specifications or these special provisions, or as required by the Engineer, promptly after award of the Contract and acceptance of the Contractor's bond.

Any delay in the work caused by late or improper submission of samples or certificates for approval shall not be considered just cause for an extension of the Contract Time. Approval of any material shall be general only and shall not constitute a waiver of the County's right to demand full compliance with Contract requirements. After actual deliveries, the Engineer will have such check tests made as he deems necessary in each instance and may reject materials, equipment, and accessories for cause, even though such materials and articles have been given general approval. If materials, equipment or accessories which fail to meet check tests have been incorporated in the work, the Engineer will have the right to cause their removal and replacement by proper materials, equipment or accessories, or to demand and secure such reparation by the Contractor as is equitable.

If any facilities are concealed without approval or consent of the Engineer, the Contractor shall uncover for inspection and recover such facilities all at the Contractor’s sole expense, when so requested and deemed necessary by the Engineer. Should it be considered necessary or advisable by the Engineer at any time before final acceptance of the entire work to make an examination of work already completed, by uncovering the same, the Contractor shall, on request, promptly furnish all necessary facilities, labor and material. If such work is found to be defective in any important or essential respect due to fault of the Contractor, his subcontractors, or material suppliers, then the Contractor shall defray all of the expenses of such examination and of satisfactory reconstruction. If, however, such work is found to meet the requirements of the Contract, then the cost of such work will be paid for as defined in Subsection 104.03, Extra Work; and compensation will be as provided for in Subsection 109.04, Compensation for Changes and Force Account Work; and in accordance with the revisions of Section 104 of these Douglas County Standard Special Provisions.

Subject to the requirements contained in the preceding sentence, inspection of materials as a whole or in part will be made at the Project Site. Neither inspection testing, approval nor acceptance of the work in whole or in part by Douglas County or its agents shall relieve the Contractor or his sureties of full responsibility for materials furnished or work performed not in strict accordance with the Contract. 105.20 ACCEPTANCE Subsection 105.20(a) shall be deleted in its entirety and replaced as follows: There will be no partial acceptance of any unit or portion of the project, unless authorized in writing by the Douglas County Engineer.

SSP-14



- continued –

Subsection 105.20(b) shall include the following: When the work under this Contract is substantially completed, the Contractor shall notify the County in writing that the work will be ready for final inspection on a definite date, which shall be stated in such notice. The notice shall bear the signed concurrence of the representative of the County having charge of the project inspection, and shall be given at least ten (10) days prior to date stated for final inspection. If the County determines that the work under this Contract is substantially completed, it will make the arrangements necessary to have final inspection commenced on the date stated in such notice, or as soon thereafter as practical. 105.21 DISPUTES AND CLAIMS FOR CONTRACT ADJUSTMENTS Subsection 105.21 shall include the following: All disputes arising under this Contract or its interpretation whether involving law of fact or both, or extra work, and all claims for alleged breach of contract shall within seven (7) days of commencement of the disputes, be presented by the Contractor to the Engineer in writing for decision. All papers pertaining to claims shall be filed in duplicate. Such notice need not detail the amount of the claim, but shall state the facts surrounding the claim in sufficient detail to identify the claim together with its character and scope. In the meantime, the Contractor shall proceed with the work as directed. Any claim not presented within the time limit specified within this paragraph shall be deemed to have been waived, except that if the claim is of a continuing character and notice of the claim is not given within seven (7) days of it commencement, the claim will be considered only for a period commencing seven (7) days prior to the receipt by Douglas County of notice thereof.

The Contractor shall submit in detail his claim and his proof thereof to the Engineer. Each decision by the Engineer will be in writing and will be mailed to the Contractor by certified mail (return receipt requested) or delivered in person (acknowledgement of receipt requested). If the Contractor does not agree with any decision of the Engineer, the Contractor shall in no case allow the disputes to delay the work, but shall notify the Engineer in writing within five (5) days that the Contractor is proceeding with the work under protest, and the Contractor may then accept the matter in question from the final release. Claims for additional compensation for extra work, due to alleged errors in ground elevations, contour lines or bench marks, will not be recognized unless accompanied by certified survey data, made prior to the time the original ground was disturbed, clearly showing that errors exist which resulted or would result in handling more material or performing more work than would be reasonably estimated from the plans issued by Douglas County. Any discrepancies, which may be discovered between actual conditions and those represented by the plans, shall at once, (but no later than within twelve hours of discovery) be reported by the Contractor to the Engineer; and work shall not proceed, except at the Contractor’s risk or unless the Engineer has directed in writing the Contractor to continue working.

The Contractor shall prepare all applications required and submit them to the CDPHE.

The Contractor shall submit a copy of certification of the permit to the Engineer prior to the start of construction. The Contractor is responsible for all application permit fees. Surface water control generally falls into the following categories:

(1) Normal low flows along the channel. (2) Storm/flood flows along the channel. (3) Flows from existing storm drain pipelines. (4) Local surface inflows not conveyed by pipelines.

At a minimum, the Contractor shall be responsible for diverting the quantity of surface

flow around the construction area, so that the excavations will remain free of surface water




for the time it takes to install these materials and the time required for curing of any

concrete or grout. The Contractor is cautioned that the minimum quantity of water to be diverted is for

erosion control and construction purposes and not for general protection of the construction site. It shall be the Contractor's responsibility to determine the quantity of water which shall be diverted to protect the work from damage caused by storm water.

The Contractor shall, at all times, maintain a flow path for all channels. Temporary

structures such as berms, sandbags, pipeline diversions, etc., may be permitted for the control of channel flow, as long as such measures are not a major obstruction to flood flows, do not worsen flooding or alter historic flow routes.

The Contractor shall conduct operations in such a manner that storm or other waters may

proceed uninterrupted along their existing drainage courses. By submitting a bid, the Contractor acknowledges that they have investigated the risk arising from such waters, has prepared his bid accordingly and assumes all of said risk.

minimum of 2 feet below the foundation subgrade elevation and maintain sufficient bearing capacity for all structures, pipelines, utilities, earthwork and rock work. Such measures may include, but are not limited to, installation of perimeter subdrains, pumping from drilled holes or by pumping from sumps excavated below the subgrade elevation. Dewatering from within the foundation excavations shall not be allowed. The foundation bearing surfaces are to be kept dewatered and stable until the structures or other types of work are complete and backfilled. Disturbance of foundation subgrade by contractor operations shall not be considered as originally unsuitable foundation subgrade and shall be repaired at Contractor's expense. Any temporary dewatering trenches, settlement ponds or well points shall be restored following dewatering operations to reduce permeability in those areas, as approved by the Engineer.

All excavations made as part of dewatering operations shall be backfilled with the same

type material as was removed and compacted to ninety five percent (95%) of Maximum




Standard Proctor Density (ASTM D698) except where replacement by other materials

and/or methods are required and has been approved by the Engineer. At no time during construction shall the Contractor affect existing surface or subsurface

drainage patterns of adjacent property. Any damage to adjacent property resulting from the Contractor’s alteration of surface or subsurface drainage patterns shall be repaired by the Contractor at no additional cost to owner.

The Contractor shall remove all temporary water control facilities when they are no longer

needed or at the completion of the project. Pumps and generators used for dewatering and water control shall be quiet equipment enclosed in sound deadening devices, unless the Engineer agrees that the quieter equipment isn’t needed in isolated instances.

When the Contractor has executed an agreement with one or more of the adjacent property owner(s) that fall outside the Project limits, the necessary erosion and sediment control work shall be performed by and at the Contractor's expense. This requirement applies to, but is not limited to, the following activities: borrow pits, haul roads, storage and disposal areas, maintenance / equipment storage, staging areas, batch plants, stockpiling and etc.

New Concrete Pavement The Contractor shall profile the entire Project, from end to end, including areas not replaced with new concrete pavement. Douglas County will not accept the Project as finalized until the Contractor has profiled and made all necessary corrections to all locations. If corrective work is required, the Contractor shall submit a written corrective work proposal to the Engineer, which shall include the methods and procedures that will be used. The Contractor shall not commence any corrective work until the methods and procedures have been approved in writing by the Engineer. The Engineer’s approval shall not relieve the Contractor of the responsibility of producing work in conformity with the Contract. Corrective work on the concrete pavement shall consist only of diamond grinding or removal and replacement. Any joint sealant that is damaged by grinding on concrete pavement shall be repaired or replaced at the Contractor’s expense in accordance with Standard Plan M-412-1 and Subsection 412.18. The Contractor will re-profile the road until it is determined that the road meets the smoothness criteria as required above. Diamond grinding, joint sealant, and any restriping will not be measured and paid for separately, but shall be included in the work. Any area requiring removal and replacement shall be removed, in its entirety, full width and to the full thickness of the concrete pavement. The removal area shall begin and end with an existing transverse butt joint. The existing transverse butt joint shall be constructed with a transverse saw cut perpendicular to centerline. Replacement concrete shall be placed in sufficient quantity so the finished surface conforms to grade, thickness, and smoothness requirements in this contract. Diamond Grinding shall not reduce the planned pavement thickness by more than 0.25 inches. Cores shall be taken before and after any corrective work to verify that minimum pavement thicknesses have been maintained. A minimum of one core shall be taken every 100 cumulative feet per lane of diamond grinding, or as directed by the Engineer. Coring shall be done at the Contractor’s expense. The Engineer must be present to witness all cores removed from the concrete pavement to verify thickness. Existing Concrete Pavement In addition to the above requirements, the Contractor shall profile each through lane from beginning to end of the Project. This will include pavement surfaces that were not replaced on this Project. This profile can be combined with the new concrete pavement profiling. The Engineer, after receipt of the Project Profiles, will determine the areas requiring corrective work (diamond grinding). Grinding on areas outside new concrete pavement will be paid for in accordance with Item 202, Removal of Concrete Pavement (Diamond Grinding).

It may be necessary to use a heat lance to remove moisture and dirt from joints and cracks prior to installation. The Contractor shall vacuum any concrete slurry from sawcutting and joint sealing operations prior to opening the roadway to traffic. This shall be accomplished by vacuuming up the concrete slurry to prevent it from tracking to adjacent lanes or vehicles. 412.21 DETERMINING PAVEMENT THICKNESS Subsection 412.21 is hereby deleted and replaced with the following: For routine Project Acceptance (PA) coring requirements, the coring frequency shall be a minimum of one core per 500 linear feet taken for each travel lane (including turn lanes greater than 100-feet). When the length of any core obtained is deficient from the specified pavement thickness by more than one quarter inch, then additional cores shall be taken 200-feet ahead and back of the original cores in order to determine the extents of the deficiencies and to evaluate price reduction and / or limits or removal and replacement. Typically, cores shall not be taken beneath the anticipated wheel paths. However, the County may take additional cores to verify depth as often as desired, in order to determine the extent of the concrete pavement thickness deficiencies. Cores holes and the required epoxy grout patching will not be paid for separately, but shall be included in the work.




The length of Project Acceptance (PA) cores will be the only measurements used in determining price adjustments for deficient pavement thickness and shall be as follows:

1. When the deficiency in thickness (determined by cores) is less than 0.25 inches of the

required pavement thickness, in the area of such deficiency, then the Contractor will be compensated for 100 percent of the Unit Bid Price(s) for Item 412, Concrete Pavement (9 Inch) (Class P) and for Item 412, Concrete Pavement (9 inch) (Class E) (High Early).

2. When the deficiency in thickness (determined by cores) is greater than 0.25 inches, but

5. When the deficiency in thickness (determined by cores) is greater than 0.75 inches of the

required pavement thickness, in the area of such deficiency, then the Contractor will NOT be compensated; and County reserves the right to require the Contractor to remove the unacceptable concrete pavement at no expense to the County and replace it at the original Unit Bid Price(s) for Item 412, Concrete Pavement (9 Inch) (Class P) and for Item 412, Concrete Pavement (9 inch) (Class E) (High Early).



PORTLAND CEMENT CONCRETE PAVEMENT - Continued -

412.22 OPENING TO TRAFFIC Subsection 412.22 shall be revised to include the following At no time shall any vehicle in excess of the legal load limits for the new facility be allowed on the pavement. Newly constructed pavement shall be opened to traffic in accordance with one of the following three procedures. For any procedure below, the Engineer may extend the time during which traffic is excluded from the pavement if certain weather conditions make it advisable to do so. 1. General. All traffic shall be excluded from the newly constructed pavement until the

concrete pavement has reached a compressive strength of 2,500 psi. 2. Strength Requirements. Newly constructed pavement may be opened to traffic provided that

specimen cylinders have been made, cured and tested in accordance with AASHTO T-22 and AASHTO T-23 and have achieved a minimum compressive strength of 2,500 psi.

3. Maturity Method. At the discretion of the Engineer, the pavement may be opened to traffic when the strength of the newly constructed pavement is determined adequate using the maturity method as described herein.

3.1 General. This outlines the procedure for using the maturity concept as a nondestructive

method to determine concrete strength. This is a two-step procedure. First, a relationship must be established between the maturity values and the concrete strength as measured by destructive methods (that is, through testing of beams or cylinders). The development of the maturity-strength curve shall be done in the field at the beginning of construction using project materials and the project proportioning and mixing equipment. The second step is the instrumentation of the concrete to be measured. Temperature probes are installed in the concrete, and the temperature is measured. From those measurements, along with the age at which the measurements were taken, maturity values are determined. A maturity meter or temperature-measuring device and a computer or calculator may also be used to determine the maturity values. The Contractor shall develop a plan for performing the maturity testing for approval by the Engineer. The plan shall include:

1. The Contractor shall be responsible for the development of the maturity curve. The

Engineer and the testing firm the Engineer hires to do quality assurance testing shall monitor the curve development.

2. The temperature monitoring process of the constructed pavement shall be the responsibility of the Contractor and monitored by the Engineer.




For concrete furnished from a construction or stationary mixer which is in place prior to construction of the specified project, a maturity curve may be established ahead of actual construction of the specified project. The test specimens shall be cast with concrete made from the same plant and using the same materials source as will be used in the specified project. The Engineer shall be informed and have an opportunity to observe the development of the maturity curve.

3.2 The Maturity Concept. The hydration of cement and gain in strength of the concrete is

dependent on both curing time and temperature. Thus, the strength of the concrete may be expressed as some function of time and temperature. This information can then be used to determine the strength of concrete without conducting physical tests. The time-temperature function commonly used is the maturity concept proposed by Nurse-Saul (ASTM C1074),

M (°C x hours) = Σ [(T – T0)Δt] Equation 1

Where M is the maturity in °C-hours [M is also termed the time-temperature factor (TTF)], Δt is the time interval in hours (or days), T is the average concrete temperature during the time interval Δt, and T0 is the datum temperature at which concrete ceases to gain strength with time. The value of T0 = 0 °C (14°F) is most commonly used. As a result, Equation 1 becomes:

M (°C x hours) = Σ[(T) Δt] Equation 2

3.3 Establishment of Maturity-Strength Relationship. To establish a maturity-strength relationship for a concrete mix, a maturity meter or a thermal meter and a hydraulic testing machine are needed. The following procedure shall be used: (Note: Before using any maturity meter, check to be sure the datum temperature is set to 0ºC.)

1. Cast a minimum of seventeen (17) cylinders, according to practice C 192/C 192M as

per AASHTO T-23. Place a maturity meter in two (2) of these cylinders. Test the entrained air content and slump of the concrete being used to cast the cylinders, as per Section 701. Record these values. The cylinders shall be cast from a batch of at least 3 cu. yd.

2. Determine maturity values and strength at five different ages (4, 6, 8, 12, 24 hours). Test three specimens for compressive strength at each age and calculate the average strength at each age. Each time a set of cylinders is tested, record the temperature from both of the cylinders embedded with a maturity meter to get an average temperature.




Additional test specimens may be cast at a later time and tested at earlier ages to add data to the strength-maturity relationship as an aid to determining the appropriate time to saw.

3. Plot the measured strength against the corresponding values of maturity at different ages, as determined by the maturity meter or by hand methods. Using a computer model or hand method, determine maturity-strength relationship. The maturity-strength relationship determined by the Contractor must be approved by the Engineer prior to implementing it. Since the influence of maturity on strength of concrete is somewhat different for various mixes, a maturity-strength relationship established for one mix shall not be used for another mix.

Field Procedure.

Placement of Temperature Probes

Insert the maturity meter probe into the concrete until the end is at approximately the pavement mid-depth and 2 feet from the edge of the pavement. Check to ensure the concrete is consolidated around the maturity meter probe. Probes may be placed at any point along the pavement slab. A minimum of two probes shall be placed in each day's placement. On days when there is a large difference between daytime high temperatures and nighttime low temperatures, placing additional probes near the beginning of the day's run and at a point near the midday location would provide helpful information. This would be helpful to those sawing the pavement as well as those determining the opening time. It has been found that the concrete does not always gain strength at the same rate. Therefore the concrete placed during the middle of the day can gain strength faster than the concrete placed at the beginning of the day. Measuring the Maturity The maturity number can be read directly from a maturity meter or calculated from the temperature readings obtained by a thermal meter. This number is then used to enter the strength-maturity chart that was established as described above, and a strength is then determined.




Validation

The Engineer shall have the option of performing validation tests to determine if concrete strength is being represented by the current maturity curve. The geotechnical firm may be required to cast and cure three (3) cylinders using the same procedure and manner as used to develop the current maturity curve. Test all three cylinders as close as possible to the maturity value which was determined to represent the opening strength of the pavement. If the average of these tests is within 50 psi of the original curve at the TTF that the validation cylinders were tested, the original curve shall be considered validated. If the average value is less than 50 psi of the original maturity curve at the TTF the validation cylinders were tested, a new maturity curve shall be developed. If the average value is greater than 50 psi of the original maturity curve at the TTF the validation cylinders were tested, a new maturity curve may be developed.

This validation procedure is intended to be similar to the assurance procedure in that it is not an acceptance test, but merely a check. If the test results indicate a new curve must be developed, this should be done in a timely manner. The curve currently being used shall be continued until new cylinders can be cast, and at that point, the implementation procedure described above shall be followed.

BASIS OF PAYMENT

Subsection 412.24 shall be revised to include the following: Payment for joint sealant on new 8 inch Concrete Pavement (Class E or Class P) shall include, but not be limited to, removal of dirt, sandblasting, sweeping, traffic control, sawcutting, backer rod and joint sealant.
