GAOA Parque Creek Road Repair Statement of Work

C.1 Scope of Work:

Work will consist of repairing a road segment that has slumped down the embankment at ~MP

4.2 of NFSR 504. Material from the failed road prism will be excavated, sorted, and stockpiled for future use, or hauled to a designated waste area.

Two waste areas are anticipated for the project. The first waste area is located adjacent to the slide location and the second is approximately 1.15 miles from the slide location.

Special rock embankment will be placed in the excavation area followed by unclassified burrow material sourced from the excavated material, a 6” layer of roadway aggregate will be placed on top to provide the finished driving surface. See Sheet A2 of plans for detailed typical section.

Work will require hauling large quantities of material from commercial pit source(s), sorting and hauling excavated material, placing, and compacting special rock embankment, unclassified burrow material and aggregate under moisture-controlled conditions, and improving/maintaining haul route(s) and access roads on the National Forest Service Road System.

Minor clearing, grubbing, seeding, and erosion control work will be performed.

Finish grading, installation of culverts, slope grading, and misc. work will be included in the project.

The aggregate material must meet FS Gradation U or WYDOT Grade W ‘Gravel Road’ gradation (See Exhibit A: Gradation requirements for WYDOT Grade W ‘Gravel Road’ and FS Gradation U aggregate) at the end of this section. Arrangements must be made with local commercial sources to supply the quantity of material requested, and that the material can meet gradation requirements of this contract.

NFSR 285 – Wiggins Fork Work shall consist of roadway reconditioning for ~3.0 miles, see plan set and FSSS for detailed specifications.

NFSR 504 – Parque Cr Work shall consist of roadway reconditioning for ~4.2 miles. One cattle guard cleaning is anticipated and will be flagged by CO prior to work. Work shall also address slide repair at ~ MP 4.2, see plan set and FSSS for detailed specifications.

Testing:

The government is requesting a minimum of 1 gradation verification test (including Plasticity Index (P.I.)) per material source used on this project to ensure that materials are within conformance of the contract specifications.

Material must be tested as per Section 301 and 703.05 of the FP-14 (AASHTO T-11, T-27, and AASHTO T-89) and have test results submitted to and approved by either the CO or the Zone Engineer before any material will be accepted onto the project.

If any subsequent gradation tests identify deficiencies in materials, the materials will NOT BE ACCEPTED onto the project until the contractor can ensure that all services and materials conform with contract specifications.
