About this file
This is a technical layout drawing for the Speed Cushions Installation Project in Pennsylvania, detailing the specifications for asphalt speed cushion construction on N 3rd Street. The project involves installing speed cushions (also referred to as speed humps, W17-1 design) at multiple locations along the roadway in accordance with PennDOT Publication 408 standards and the latest MUTCD guidelines. The drawing provides typical cross-sectional details showing speed cushion dimensions of 6 feet wide by 14 feet long with a height profile ranging from 0 inches to 3 inches, with specific measurements at various points (3.00", 2.91", 2.67", 2.25", 1.65", and 0.90"). The plan indicates spacing of 5 feet (TYP) between cushions, 6-inch typical dimensions for markings, and includes notes that final locations are approximate and will be determined prior to construction. Installation requirements specify milling 2 inches of existing pavement and applying a tack coat prior to speed cushion placement. The white markings measure 12 inches and are applied at typical intervals along the center line.
The drawing serves as Appendix A5 to the bid solicitation and establishes the technical baseline for contractor submissions. The project documentation notes that bids containing omissions resulting from industry assumptions will be deemed non-responsive, emphasizing that all bidding requirements are explicitly included in the solicitation materials and PennBid profile. Prime and subcontractors must identify their interest in bidding through the project profile. The work must conform to approved Speed Cushion Details and applicable provisions of referenced standards, with a questions and answers guide available in the solicitation documents to clarify technical and contractual requirements prior to bid submission.
