2.2. PURPOSE

The intended use/purpose for this Invitation For Bid:

The intended purpose for this IFB is to provide the specifications to obtain an annual pricing contract for application of Tire Rubber Modified Surface Sealer (TRMSS) which will be applied as a fog seal system on

The bidder is to submit a bid that will be fixed for one (1) year. A price re-determination may be considered by

Collin County only at the anniversary date of the contract. On each anniversary date of the contract, the

Contractor may request a price redetermination in their bid, dependent upon fluctuations in the Producer

Price Index (PPI); Group: Maintenance and Repair Construction, Services; Series ID WPUIP2320002, as published by the U.S. Department of Labor, Bureau of Labor Statistics, Washington, D.C. 20212 at https://data.bls.gov/cgi-bin/srgate. Other documented price adjustments such as direct cost, labor, materials, and/or delivery costs may be considered at the County’s discretion.

Should a contractor fail to submit the request and supporting documentation to the proper location ninety

(90) days before the anniversary date, contractor shall be deemed to have waived its right to any redetermination in price. The anniversary date will be the day the contract was awarded by Commissioners

Court of each year. The ‘base’ month for determining adjustments will be the sixth (6th) month prior to the anniversary date of the contract. The base month is fixed and will not be adjusted year to year. The adjustments will be based on the difference in the base month for each applicable year and will become effective on the first day of the anniversary month.

2.40. EQUIPMENT

1. Contractor shall furnish the necessary facilities and equipment for determining the temperature of the mixture, regulating the application rate, and securing uniformity at the junction of two distributor loads. The vendor shall ensure that all equipment provided under this contract is in fully operational and functional condition at all times during the service period.

2. All construction equipment involved in roadway work shall be equipped with permanently mounted three-hundred-sixty (360) degree revolving or strobe warning light with amber lens. The light shall have a minimum lens height of five (5) inches. This light shall have a mounting height of not less than six (6) feet above the roadway surface and shall be visible from all sides. This equipment shall have attached at each side of the rear end of the vehicle an approved orange warning flag mounted not less than six (6) feet above the roadway surface.

3. Ensure equipment and materials are a minimum ten (10) feet from the edge of the traveled roadway during non-working hours. The contractor is responsible for obtaining permission to park outside of the right-of-way, on private property, from the property owner.

4. Remove from the roadway and store in a central location approved by the County all temporary traffic control devices, such as cones, barrels, portable signs, vertical panels, etc., which will not be used in twenty-four (24) hours. This includes removal of temporary traffic control devices from the roadway over the weekend.

5. Contactor’s equipment and vehicles shall not be maintained on site during construction, except at designated maintenance sites as approved by the County or the County employee assigned to the projects by the County.

2.41. CONSTRUCTION

1. Remove or protect existing raised pavement markers. Repair any damage incurred by removal as directed. Remove dirt, dust or other harmful material before sealing following “Texas Standard

Specifications for Construction and Maintenance of Highways, Streets And Bridges, 2024” Item 738

Cleaning and Sweeping Highways prior to starting application.

2. Apply the mixture when the air temperature is 60 degrees Fahrenheit and above, or above 50 degrees

Fahrenheit and rising. Measure the air temperature in the shade away from artificial heat. The County will determine when weather conditions are suitable for application. The County will select the application temperature within the limits recommended in Item 300, “Asphalts, Oils and Emulsions”.

Apply the material within 15 degrees Fahrenheit of the selected temperature.

3. Adjust the shot width so operations do not encroach on traffic. Use paper or other approved material at beginning and end of echo shot to construct a straight transverse joint and prevent overlapping applied material. Use sufficient pressure to flare the nozzles fully. Distribute material at the rate shown on the plans or as directed. When an excessive quantity of asphalt is applied, furnish and uniformly distribute clean, fine sand on the surface to blot the excess. Maintain ingress and egress as directed by applying sand to freshly sealed areas.
