R000943. 0550 - Sleepy Hollow and Moyer Road Culvert Replacements.

West Hanover Township, Dauphin County, Pennsylvania is requesting bids for removal and replacement of five culverts along Sleepy Hollow Road and Moyer Road, with bids due November 19, 2026 at 11:00 a.m. via PennBID. The project is subject to Pennsylvania Act 141 of 2022, requiring all bidders and subcontractors to register with and utilize the Federal E-Verify system.

The scope includes removal and replacement of culverts with pipes of various diameters, headwalls, endwalls, riprap aprons, and slope stabilization. The project manual references five construction activities with comprehensive erosion and sediment control plans, and detailed design specifications for at least one aluminum box culvert (#4R1, 10-foot span, 4-foot-10-inch rise, 40-foot-6-inch length) complying with AASHTO LRFD bridge design and ASTM standards for corrugated aluminum alloy structural plate. The scope includes fish baffles, full aluminum invert plate systems, corrugated headwalls at inlet and outlet, reinforcing ribs, and deadman anchors. Site-specific construction requirements address assembly tolerances, engineered backfill material specifications (AASHTO soil classifications A-1, A-2-4, or A-2-5), compaction density mandates, electrochemical backfill and water properties (pH 4–9, resistivity exceeding 500 ohm-cm), geotextile protection, and equipment weight restrictions (maximum 10 tons static mass within 5 feet of structure until minimum cover achieved).

A General Permit (GP-11) was approved by the Pennsylvania Department of Environmental Protection on December 22, 2025, authorizing maintenance, repair, and replacement of water obstructions and encroachments. A GP-4 permit application for storm sewer and outfall work remains pending DEP authorization and requires separate approval before work commences in that area. Bidders must submit a Non-Collusion Affidavit and Public Works Employment Verification Form. Bid security of 10 percent of the bidder's maximum bid price is required. Site visits are required; no pre-bid conference will be conducted. The successful bidder must execute the contract and furnish required bonds within 15 days of Notice of Award.
