WY – BB Visitor Center Parking Lot Solicitation # 140R6021Q0014

STATEMENT OF WORK

1.0 Background

The work included in this solicitation consists of subsurface explorations at a parking lot and access road at the Buffalo Bill Dam Visitor Center on U.S. Highway 16/20, the Cody to Yellowstone Highway, approximately 6 miles west of Cody, Wyoming.

The Visitor Center parking lot and access road are reportedly composed of uncontrolled material from tunnel and road cut excavation spoils wasted/dumped during widening of U.S. Highway 16/20 and construction of the Shoshone Canyon Tunnel. The tunnel and road cut were excavated using drill and blast methods through various rock types, mapped as dolomite, dolomitic limestone, shale, limestone conglomerate, and granite. The rocks exposed in the road cut are also locally intersected by a fault.

The character of the uncontrolled fill comprising the Visitor Center parking lot and access road is unknown. However, based on available construction photographs, it is anticipated to contain clay or silt to boulder-sized materials (soil and rock) that was dumped and wasted over the original reservoir shoreline. Portions of the fill may have been placed on unconsolidated colluvial deposits of variable character, potentially containing boulders. During the 1980’s Buffalo Bill Dam construction modification project, the Visitor Center Parking Lot was used as contractor staging area and a haul road, and additional fill materials were added. Following the dam modification, the staging area and haul road were paved with asphalt to create the Visitor Center parking lot and access road to the Visitor Center and dam.

Shortly after the dam modification project, tension cracks in the asphalt and sloughing of the shoreline slope was observed, indicating fill slope movements. Repairs were made in the 1990s including the addition of slope revetment and replacement of the damaged asphalt pavement.

Similar movement and pavement cracking have been noted in recent years.

2.0 Scope

The work to be completed under this contract includes providing a geotechnical data report which will be comprised of data from five exploratory drill holes, soil and bedrock sampling, laboratory testing and inclinometer casing installations in two of the drill holes. The details of specific tasks and deliverables are discussed in the following sections. The intent of the work is to provide the government with data to characterize the subsurface conditions at the Visitor Center parking lot and access road. Geotechnical interpretations or recommendations are not part of the scope.

3.0 Objectives

The purpose of this work is to provide subsurface data for planning and design of potential repairs to the parking lot and access road. Primary objectives of the work are to collect and report subsurface data to identify the depth to bedrock beneath the parking lot and access road, characterize the uncontrolled fill material, and install inclinometer casings for future monitoring (by the government) of the fill movement.

The subsequent drill hole depths may be adjusted by the Government Representative so long as the total drill hole length does not exceed 180 feet. The Contractor shall not drill more than 180 total linear feet unless otherwise directed by the QAE.

As part of the drilling activities, the Contractor shall advance drill holes through approximately 3 inches of asphalt pavement (core or saw cut and patch), approximately 6 inches of road base materials, uncontrolled fill material that reportedly consists of tunnel and road cut excavation spoils dumped/wasted at the location of the parking lot and access road, potential underlying colluvium or residuum, and underlying bedrock. The uncontrolled fill material is likely to range from clay or silt to boulder-sized materials (soil and rock) and may include a minor amount of organic material.

The Contractor shall conduct a maximum total of 20 SPTs according to ATSM D1586, including a maximum of four (4) SPTs per drill hole. The Contractor shall attempt to conduct a SPT at intervals of each 5 feet of depth; one SPT between 0 to 5 feet, 5 to 10 feet, 10 to 15 feet, and 15 to 20 feet from the top of the asphalt surface. The Contractor should try to avoid advancing SPTs where cobble and boulder-sized material or bedrock is expected to result in immediate refusal or damaging of the sampling equipment. The Contractor shall use an automatic hammer to conduct SPTs. Refusal shall be at 50 blows within a six-inch-test interval or 10 consecutive blows with no advancement. SPT samples shall be logged and processed as specified in Section 4.1.3.

The Contractor shall switch to HQ or HQ3 diameter rock coring methods at the top of bedrock. The Contractor shall advance rock core drilling and collect HQ or HQ3 diameter rock core samples to a minimum depth of 10 feet below the top of bedrock.
