Upon receiving notice of such suspension, the Contractor shall discontinue said work, or such parts of it as the Council may designate. Upon such suspension, the Contractor's control shall terminate and thereupon the Council or its duly authorized representative may take possession of all or any part of the Contractor's materials, tools, equipment and appliances upon the premises, and use the same for the purpose of completing said contract, and hire such force and buy or rent such additional machinery, tools, appliances and equipment and buy such additional materials and supplies at the Contractor's expense as may be necessary for the proper conduct of the work and for the completion thereof; or may employ other parties to carry the contract to completion, employ the necessary workmen, substitute other machinery or materials and purchase the materials contracted for, in such manner as the Engineer may deem proper; or the Engineer may annul and cancel the contract and relet the work or any part thereof. Any excess of cost arising therefrom over and above the contract price will be charged against the Contractor and his sureties, who will be liable therefore. In the event of such suspension, all money due the Contractor or retained under the terms of this contract shall be forfeited to the City, but such forfeiture will not release the Contractor or his sureties from liability for failure to fulfill the contract. The Contractor and sureties will be credited with the amount of money so forfeited toward any excess of cost over and above the contract price, arising from the suspension of the operations of the contract and the completion of the work by the City as above provided and the Contractor will be so credited with any surplus remaining after all just claims for such completion have been paid. On completion of the contract, the original Contractor shall be entitled to the return of all unused materials, equipment, tools, and appliances, except that the Contractor shall have no claim on account of unusual and ordinary depreciation, loss and wear and tear. In the determination of the question whether there has been any such non-compliance with the contract as to warrant the suspension or annulment thereof, the decision of the Engineer shall be binding on all parties to the contract PERFORMANCE OF SURETIES In the event of any termination as hereinbefore provided, the Engineer shall immediately give written notice thereof to the Contractor and to the Contractor's sureties, and the sureties shall have the right to take over and perform the contract; provided, however, that if the sureties, within five (5) days after receiving, said notice of termination, do not give the City written notice of their intention to take over the performance of the contract, and do not commence performance thereof within five (5) days after notice to the City of such election, the City may take over the work and prosecute the same to completion as hereinbefore provided FLOOD EVACUATION Contractor shall be prepared to evacuate the construction site during a Flood Watch issued by the National Weather Service.

The Contractor shall provide a sequence and manner of rolling which will define maximum compaction by establishing a rolling vs. density chart that shows the progress of densification from initial laydown through maximum obtainable density at the break over point. The Contractor will determine relative compaction on the quantity within the test strip by measuring nuclear gage density. If the relative compaction of quantity within the test strip or any lot does not meet the density requirements of these special provisions, the Contractor shall construct additional test strips to define the maximum density obtainable for the millings being produced; the rates of emulsified recycling agents, additives, and water; and the site conditions. Cold in-place recycling operations may continue through the first day, unless the Contractor s equipment and process fail to meet the requirements for successful completion of cold in-place recycling operations in conformance with these special provisions. Recycling operations shall not continue until a test strip conforming to the special provisions has been constructed and approved by the Engineer. Test strips that do not conform to the special provisions shall be reworked, re-compacted, or removed and replaced at the Contractor's expense and to the satisfaction of the Engineer. Upon acceptance of the test strip by the Engineer, the Contractor shall use the same equipment, materials, and construction methods for the remainder of recycling operations, unless adjustments are made by the Contractor and approved by the Engineer. If adjustments are made, the Contractor will produce a new test strip to define the maximum density. Proportioning During the Cold In-Place Recycling Operation Cement or lime slurry shall be metered or weighed into the mass of the cold milled material using a mass flow, coriolis effect, type meter that will accurately measure the amount of cement or lime slurry to within 5 percent of the amount required by the mix design or as adjusted in the field. Dry spreading of lime or cement shall be by means of a mechanical spreader capable of spreading the additive at a prescribed weight per unit area. The spreader shall have working scales and distance measuring devices to control the spread rate as required by these special provisions. Emulsified recycling agent shall be metered or weighed into the mass of the cold milled material using a mass flow, coriolis effect, type meter that will accurately measure the amount of emulsified recycling agent to within 0.5 percent of the amount required by the mix design or as adjusted in the field. Spreading and Compaction Prior to pick up by the paver, remove and dispose of all visible oversized crack filler in the cold milled material or in the recycled pavement mixture. When a paving fabric is encountered during the recycling operation, the Contractor shall make the necessary changes in equipment or operations so that 83

95 incorporation of the shredded fabric in the recycled material does not affect gradation, or inhibit placing or compaction of the recycled material. No fabric piece incorporated into the recycled section shall have any dimension exceeding a length of 2 inches. The Contractor shall be required to remove and properly dispose of oversized pieces of paving fabric or as directed by the Engineer. The recycled pavement mixture shall be graded and compacted to the depth, lines, and grades established by the plans or Engineer and as required by these special provisions. The recycled pavement mixture shall exit from the mixing chamber in a manner that prevents particle segregation. Care shall be exercised while spreading to avoid segregation, tearing, or scarring of the final compacted surface. Rolling shall commence at a time interval following the milling, mixing, and spreading of the recycled pavement mixture as determined by the mix design or directed by the Contractor. Time intervals shall be based on ambient temperatures, weather, and type of emulsified recycling agent. When possible, rolling shall not be started or stopped on uncompacted material. Compacting of the recycled pavement mixture shall be completed using rollers meeting the requirements of these special provisions. The rolling pattern shall be changed and a new rolling pattern shall be established when: 1. Relative compaction cannot meet the requirements of these specifications. 2. There are changes in recycled pavement mixture or proportions. 3. There are changes in placement equipment or procedures. 4. There is a significant change in temperature or weather conditions or controlling factor. 5. There is major displacement and/or cracking of the recycled pavement mixture. The final compacted surface of the recycled pavement mixture shall be free of ruts, bumps, indentations, raveling, irregularities, or segregation and shall meet the smoothness requirements of these specifications. Cold in-place recycled asphalt concrete that does not conform to these special provisions shall be reworked, re-compacted, or removed and replaced at the Contractor's expense. Initial Compaction After compaction but prior to opening the roadway to traffic, the average in-place density shall be determined based upon nuclear gage readings at random locations. During in-place density testing of the compacted recycled pavement, the nuclear gauge shall be set to the recycled section thickness. The average in-place density shall be used to calculate the relative compaction for each lot. The relative compaction shall be not less than 95 percent or greater than 105 percent of the maximum density obtained in the test strip as required in these special provisions. If additional rolling does not achieve relative compaction, a new rolling pattern shall be established such that a new maximum density is determined. However, care should be taken not to over-roll the mat based on visual observations of check cracking or shoving. Opening to Traffic After initial compaction has been achieved, and prior to opening the recycled pavement mixture to traffic, the Contractor shall apply a fog seal of dilute (1:1) SS-1h emulsion, dilute emulsified recycling agent or equivalent at a rate of 0.08 to 0.12 gallon per square yard to all areas opened to traffic. Immediately following application of the fog seal, the cold in-place recycled pavement surface shall be covered with sand at a rate of 1.0 to 2.0 pounds per square yard. The exact rate will be determined by the Contractor. Excess sand shall be removed from the pavement surface by sweeping. Sand shall be free from clay or organic material. 84

96 Cure, Maintain and Protect CIR Surface The CIR must cure in place before supplemental compaction and placement of the HMA or RHMA surface for either: 1.

Maintain and protect finished CIR surface until the HMA or RHMA surfacing is placed. Maintain an even and uniform surface. Immediately repair any damage or defects by: 1. Reworking and recompacting the CIR 2. Replacing and damaged area with the same depth of HMA placed using the Method Process Damage to the completed recycled material shall be repaired by the Contractor at the Contractor s expense. No extra compensation will be allowed. Supplemental Compaction Recompact the CIR after cure and prior to smoothness testing of the CIR and placement of the HMA or RHMA surfacing. Use the same equipment and construction methods that were used for the initial compaction. Adjustments to equipment and methods must be authorized by the Engineer. Use the same lot limits for supplemental compaction as for initial compaction. On the first day of supplemental compaction operations, construct a test strip using the methodology outlined above. The maximum test density shall be equal to or greater than the initial test strip max density used. Proceed with supplemental compaction after test strip is approved by Engineer. Do not continue supplemental compaction if the required relative compaction is not met. Provide a rolling versus density chart that shows the progress of densification from initial pass to final pass at maximum obtainable density at the break over point. Any subsequent surface treatment or overlay of the recycled pavement shall not be placed until the relative compaction of the recycled pavement layer meets the requirements for supplemental compaction as defined herein. Test each lot in the same manner as the initial compaction using 10 random test sites. Report new initial average density. If the average compaction does not increase or be equal or greater to 97% but not greater than 103% of the supplemental test strip maximum density, adjust equipment or methods to achieve the required results. Report the following for each lot: 1. Date of supplemental compaction and Lot designation 2. Maximum obtainable density from supplemental test strip 3. Average relative compaction based on 10 random nuclear test points 4. Average of initial relative compaction 5. Ambient and compacted recycled pavement surface temperatures.

120 PROPOSAL TO THE CITY OF NAPA DEPARTMENT OF PUBLIC WORKS 2011 COLD IN-PLACE PAVEMENT RECYCLING PROJECT City of Napa Project No. ST10PW07 Federal Project No. STPL 5042(051) NAME OF BIDDER ADDRESS CITY, STATE, ZIP CODE TELEPHONE NO: AREA CODE ( ) FAX NO: AREA CODE ( ) CONTRACTOR LICENSE NO. The work for which this proposal is submitted is for construction in conformance with the special provisions (including the payment of not less than the State general prevailing wage rates), the project plans described below, including any addenda thereto, the contract annexed hereto, and also in conformance with the City of Napa Standard Specifications and Standard Plans dated July 2008, the California Department of Transportation Standard Plans, dated May, 2006, the Standard Specifications, dated May, 2006, and the Labor Surcharge and Equipment Rental Rates in effect on the date the work is accomplished. The special provisions for the work to be done are dated July 2011 and are entitled: CITY OF NAPA DEPARTMENT OF PUBLIC WORKS NOTICE INVITING BIDS, PROPOSAL, CONTRACT AND SPECIAL PROVISIONS FOR COLD IN-PLACE PAVEMENT RECYCLING PROJECT, FEDERAL PROJECT NO. STPL-5042(051) The project plans for the work to be done were approved July 2011 and are entitled: CITY OF NAPA DEPARTMENT OF PUBLIC WORKS PROJECT PLANS FOR COLD IN-PLACE PAVEMENT RECYCLING PROJECT, FEDERAL PROJECT NO. STPL-5042(051) Bids are to be submitted for the entire work. The amount of the bid for comparison purposes will be the total of all items. The bidder shall set forth for each unit basis item of work a unit price and a total for the item, and for each lump sum item a total for the item, all in clearly legible figures in the respective spaces provided for that purpose. In the case of unit basis items, the amount set forth under the "Item Total" column shall be the product of the unit price bid and the estimated quantity for the item. In case of discrepancy between the unit price and the total set forth for a unit basis item, the unit price shall prevail, except as provided in (a) or (b), as follows: (a) If the amount set forth as a unit price is unreadable or otherwise unclear, or is omitted, or is the same as the amount as the entry in the item total column, then the amount set forth in the item total column for the item shall prevail and shall be divided by the estimated quantity for the item and the price thus obtained shall be the unit price; (b) (Decimal Errors) If the product of the entered unit price and the estimated quantity is exactly off by a factor of ten, one hundred, etc., or one-tenth, or one-hundredth, etc. from the entered total, the Cold In-Place Pavement Recycling Project Federal Project No. STP-5042(051) P-1

121 discrepancy will be resolved by using the entered unit price or item total, whichever most closely approximates percentage-wise the unit price or item total in the Copy of Engineer s Estimate of cost. If both the unit price and the item total are unreadable or otherwise unclear, or are omitted, the bid may be deemed irregular. Likewise if the item total for a lump sum item is unreadable or otherwise unclear, or is omitted, the bid may be deemed irregular unless the project being bid has only a single item and a clear, readable total bid is provided. Symbols such as commas and dollar signs will be ignored and have no mathematical significance in establishing any unit price or item total or lump sums. Written unit prices, item totals and lump sums will be interpreted according to the number of digits and, if applicable, decimal placement. Cents symbols also have no significance in establishing any unit price or item total since all figures are assumed to be expressed in dollars and/or decimal fractions of a dollar. Bids on lump sum items shall be item totals only; if any unit price for a lump sum item is included in a bid and it differs from the item total, the items total shall prevail. The foregoing provisions for the resolution of specific irregularities cannot be so comprehensive as to cover every omission, inconsistency, error or other irregularity which may occur in a bid. Any situation not specifically provided for will be determined in the discretion of the City of Napa, and that discretion will be exercised in the manner deemed by the City of Napa to best protect the public interest in the prompt and economical completion of the work. The decision of the City of Napa respecting the amount of a bid, or the existence or treatment of an irregularity in a bid, shall be final. If this proposal shall be accepted and the undersigned shall fail to enter into the contract and furnish the two bonds in the sums required by the State Contract Act, with surety satisfactory to the City of Napa, and the insurance certificates within ten days, not including Saturdays, Sundays and legal holidays, after the bidder has received notice from the City of Napa that the contract has been awarded, the City of Napa may, at its option, determine that the bidder has abandoned the contract, and thereupon this proposal and the acceptance thereof shall be null and void and the forfeiture of the security accompanying this proposal shall operate and the same shall be the property of the City of Napa.
