PHL Landslide Construction The following is a brief description of the proposed scope of work. Overburden (soil) Removal: Controlled stripping and removal of the overburden overlying bedrock along the face of the slope. Overburden (soil) Regrading: Controlled stripping and regrading of the overburden along the eastern portion of the project area. The regrading and removal of excess overburden reduces the potential of slope failure in that area, preventing damage to the facilities and equipment located at the toe. Scaling: Controlled rock scaling along the slope areas to remove loose and unstable rock blocks from the face. Scaling will reduce the likelihood that rockfalls will occur. Concrete T-walls: Pre-cast concrete T-walls should be installed at the toe of the slope and cabled together to prevent rockfall debris from reaching the powerhouse, and hence protect existing structures. Draped Mesh: A draped mesh should be installed along the face of the slope to prevent rockfall debris from reaching the powerhouse area, and hence to protect existing structures. Catchment Fence: Steel cable and wire mesh catchment fence should be erected at the toe of the slope to prevent rockfall debris from reaching the transformer yard and switchgear building, and hence to protect existing structures. Secant Pile Retaining Wall: Construction of a secant pile retaining wall to stabilize the upper access road during the stripping and grading of the overburden on the slope downstream of the right abutment of the dam. Stormwater Detention Vault: Due to the area of disturbance and VADEQ regulations the construction of a detention vault is necessary to limit the increased runoff in the project area due to the stripping and regrading of the soil. In addition to the construction of a detention vault, several new stormwater pipes will be installed, and several other drop inlets and pipes will be replaced to handle the increased runoff on the stripped portion of the slope. Miscellaneous Stormwater Feature Maintenance: To control and direct stormwater runoff to the detention vault and reduce the likelihood of water running along the upper access road (similar to what transpired during the 2020 slope failures), ditch maintenance and cleanout for the upper access road is incorporated into the design. Additionally, the replacement of an existing stormwater drop inlet, culvert and headwall to facilitate drainage away from the upper access road ditch is planned. Construction of the Switchgear Building: The building which houses the switchgear equipment was destroyed by the landslide. Once built the new switchgear equipment will be put in place for reconnection of the powerhouse.

W912PM23B0024 The U.S. Army Corps of Engineers, Wilmington District requires a contract to construct or otherwise implement hillslope reinforcement and stabilization measures along the southern hillslope abutment of Philpott Dam, in response to recent landslide activity. Work will include steep slope areas (roughly 1.2 to 1.5 H: 1.0 V), with a length of about 450 ft. (cross-slope), a width of around 270 ft. (downslope) and a height of about 185 ft. Construction measures will include but may not be limited to: road stabilization; secant pile wall installation into competent soil and bedrock (Hillslope soils vary in particle size and mineralogy and are the weathering products of an underlying mica schist. As a result, soils within the project area generally consist of a schist-derived saprolite, along with interbedded silts, clays, and relict sand and gravel-sized quartz, feldspar, mica schist, and other particles. Additionally, the bedrock surface is undulatory and generally underlies the soil profile. However, isolated rock outcrops of weathered schist exist which are characterized by groundwater staining, as well as small, localized areas of open jointed bedrock.); removal and disposal of overburden soil, lose rock, and woody vegetation from steep slopes; re-grading of soil on slopes; rock scaling; rock anchor installation and stressing; wire mesh slope drape installation and anchoring; temporary and permanent rock fall catchment installation; construction of erosion and sedimentation control measures; and construction of stormwater vaults and other stormwater control measures .The contractor shall not use blasting technologies on the site. In addition to constructing hillslope stabilization measures, the contractor shall also construct an electrical switchgear building. The switchgear building shall be a pre-engineered metal building with an integrated set of mutually dependent components and assemblies that form a metal building system capable of withstanding structural and other loads, as well as exposure to weather without failure or infiltration of water into the building interior. Approximate building area will be 800 ft2 with dimensions of about 20 ft X 40 ft. SPECIAL NOTE: There is currently contractor(s) performing Powerhouse and Electrical Utility Infrastructure construction at this site. This work is expected to continue during the construction period for this solicited project. The successful bidder will be required to maintain access to the powerhouse and utility corridor areas of construction so as not to interfere with other contractors during construction of this project. To mitigate interference, AEP projects to install the transmission line to the top of the hill and then stop until the hillside is done. However, the successful bidder will need to collaborate with AEP to discuss/approve the proposed pole foundations that will need to go into the hillside for the final span of the transmission line. Finally, the contractor shall comply with all applicable federal and state environmental laws, regulations, statutes, and rules. This solicitation is unrestricted. The contract issued will be Firm Fixed Price. Note: A price evaluation preference for HUBZone small business concerns shall be used in acquisitions conducted using full and open competition. The Magnitude of Construction of this project is between $25,000,000 and $100,000,000. This solicitation will be issued in electronic format only and will be available on or about 07 July 2023. The bid opening date will be specified in the solicitation when it is issued. No additional media (CD-ROM, floppy disks, facsimiles, etc.) will be provided. Paper copies of this solicitation will not be available. Other methods of requesting a package will not be honored. The North American Industry Classification System (NAICS) code is 237990 – Other Heavy and Civil Engineering Construction and the size standard is $39,500,000.00. Bidders must be registered in the System for Award Management (SAM) in order to be eligible to receive an award from any Government solicitation.
