Mayfield Dike, Toe Drain Replacement in Archbald, PA

The U.S. Army Corps of Engineers, Baltimore District (NAB), has been tasked to solicit for and award construction services for Mayfield Dike, Toe Drain Replacement in Archbald, PA. The proposed project will be a competitive, firm-fixed-price, contract procured in accordance with FAR 14, Sealed Bidding, via an Invitation for Bid (IFB). Mayfield Dike is located in Archbald, PA (Lackawanna County), approximately 11 miles northeast of Scranton and 3 miles southeast of Carbondale. The Mayfield Dike is associated with the Aylesworth Creek Lake project located in the northeastern part of Lackawanna County and provides flood risk management for the town of Mayfield in association with substantial high-water events at Aylesworth Creek. The purpose of this contract is to replace the existing toe drain at Mayfield Dike. The project consists but is not limited to the repair, construction and installation of the following: Objectives: The US Army Corps of Engineers at Aylesworth Creek Lake in Archbald, Pennsylvania requires removal of an existing 12-inch diameter Corrugated Metal Pipe (CMP) and replacement with new 8-inch diameter High Density Polyethylene (HDPE) pipe. The work shall include excavating into the existing toe-drain; replacing the existing drainage zone pervious material to the lines and grades shown on the drawings with new drainage zone material and geotextile; replacing the pipe; placing a precast inlet box; placing precast headwall and wingwalls unit at the discharge end; backfilling; grading the site as shown on drawings; and performing a video camera inspection of the toe-drain system upon completion of work. The Contractor shall provide all labor, supervision, materials, equipment, supplies, and transportation to complete the work. Pre-Construction Survey: A topographic survey was not performed as part of the design of this project. Prior to any construction, the contractor shall hire a licensed surveyor to perform a basic survey of the area. In particular the survey shall record the invert elevation of the existing pipe outlet and general ground elevations in the area of the toe drain system. This information will be necessary for the contractor to size features such as the inlet box (i.e. to ensure the depth of the box is properly selected for the top to be flush with finished grade and the pipe penetration holes at correct elevations). Survey information shall be submitted to the government who will work with the contractor to ensure that final elevations for structures/pipes are fixed accordingly prior to ordering of materials and start of construction. Final Record Drawings (As-Builts): Submit the As-Builts drawings after completion of work to correctly show the features of the project as it has been constructed by bringing the contract set into agreement with approved working as-built prints, and adding such additional drawings as may be necessary. These working as-built marked prints must be neat, legible and accurate. Provide both PDF and Autocad 2018 version files for As-Builts. Emergency Requirements: Throughout the work, the contractor shall maintain equipment and sufficient excavated material on site to perform emergency backfilling of all open excavation within 24 hours of notification by the Contracting Officer’s Representative (COR). This requirement is intended to ensure that the integrity of the dike system is maintained in an extreme flood event where Aylesworth Lake extends to the dike area. A written plan for emergency backfilling shall be submitted prior to excavation and shall be discussed between the Contractor, COR, Dam Operator, Geotechnical Branch and Water Management Section. Permits and Licenses: The Contractor shall, at his/her own expense, obtain any license or permits required to perform the contract. The Contractor shall comply with all Federal, State, and Local laws and regulations and shall comply with any subsequent changes. Contractor shall be responsible for developing the Erosion and Sediment (E&S) plan and acquiring E&S permit from local governing authorities. The contractor shall be responsible for all design efforts and application fees associated with obtaining the permits. Obtain the necessary permits to perform the work cited above.
