Statement of Work: Crack Repairs

1.0 - Background

The Town of Shangri-la wishes to have crack repairs done on several Town highways in 2014. A contractor will be hired to do the actual work. The Town will provide inspection of the work and together, the Town and Contractor will determine which cracks to repair.

2.0 - Scope

The Town will hire a contractor to fill or seal cracks as needed on the Town highways listed below. The contract will pay for time and materials, but an estimate should be provided to the Town ahead of the work. The total price to be paid shall not be more than 10 percent more than the estimate agreed to by the contractor and the Town.

3.0 - Objectives

The contractor will provide equipment and personnel to repair cracks in the Town. The final objective is to seal working cracks and fill non-working cracks to add two or three years to the service life of the highways that are repaired.

4.0 - Tasks

The contractor will meet with the Highway Superintendent and review which roads may need crack repairs. During the meeting and subsequent highway tour, the contractor and Superintendent will decide which cracks to fill, which to repair, and which should not be repaired. The Cornell Local Roads Program workbook Pavement Maintenance will be used as guide for which cracks are good candidates for repair.

Prior to making the final estimate, the contractor and Superintendent should agree on the configuration (flush fill, overband, etc. for filling and sealing). Different configurations are possible, but should be agreed upon prior to the estimate from the contractor.

The contractor will make an estimate of the work to be completed along each segment of highway and provide a cost estimate for the repairs. The estimate should include costs for the following which is to be done by the contractor:

For each item in the estimate, the quantity of material, equipment, and personnel needed for each step should be provided. Weather and other construction limits should be agreed to prior to the estimate or included in the estimate by the contractor. For instance, no crack repair shall be done when it is raining.

The materials to be used shall be agreed upon prior to the work being performed and the material shall meet applicable American Society for Testing and Materials (ASTM) or American Association of State Highway and Transportation Officials (AASHTO) standards. Alternative standards from New York State Department of Transportation (NYSDOT) or industry standards are acceptable if agreed to by the Town Highway Superintendent in advance. The Town prefers the following materials to be used, but is willing to accept alternatives suggested by the contractor if proper certifications, documentation, and information is provided.

Filling Materials

Sealing Materials

Once approved, the contractor shall perform the work as outlined in the estimate.

5.0 - Delivery

Here are the deliverables for the project.

6.0 - Town Responsibility

The Town Highway Superintendent shall meet with the contractor as needed to review the work to be done. Once provided, the Superintendent shall review the estimate and determine which sections of highway should be repaired. A list of the final work to be done shall be provided to the contractor.

During the work, the Town shall have at least one person on site to act as a liaison and inspector for the work. After the work is complete, the Town shall provide acceptance /non-acceptance within 5 business days.

The Town shall pay the invoices from the Contractor within 45 days of delivery to the Highway Superintendent or Town Clerk.

7.0 - Place of Performance

The work will be on the Town highway system. For 2014, the following highways shall be done, but all roads may be included in the final list.

Total 3.5 miles

8.0 - Period of Performance

The work shall be completed during 2014, but scheduling needs to be done at least two weeks in advance so the Town can coordinate traffic control and public notification. Sealing shall be performed when the ambient temperature is at least 40 °F and rising, but no hotter than 80 °F. No sealing shall commence with a 24 hour period after rain unless the installation is accompanied with the use of a hot air lance to clean and dry the cracks. There should be no rain in the forecast and any work shall be stopped as soon as rain starts.

9.0 - Costs

The estimated cost will be determined by the contractor, but historical costs from previous jobs shows an estimated cost for 2 miles of $11,600. The historical cost is therefore $1.10 per linear foot along the highway. Including a 10% contingency, the estimate for this job is $22,400.

Estimate = $ / (Lf) × (1 + contingency) × length (mi) × ft / mi

$22,400 = Round up to 3 significant digits (1.10 $ / Lf × (1 + 10%) × 3.5 (mi) × (5,280)/mi
