About this file
This is a technical layout and specification document for the Speed Cushions Installation Project in Pennsylvania. The document provides detailed engineering plans and dimensional specifications for the installation of asphalt speed cushions on Division Street. The project involves constructing speed cushions (also referred to as speed humps, designation W17-1) at multiple locations within existing pavement, with all work to be performed in accordance with PennDOT Publication 408, the latest edition of the MUTCD (Manual on Uniform Traffic Control Devices), and approved speed cushion details. The typical layout shows speed cushions positioned across Division Street with specific dimensional requirements, including 6-foot width cushions with 1-foot-6-inch spacing on either side, positioned 2 feet from the existing curb on each side of the roadway. The plans indicate that final cushion locations are approximate and will be determined prior to construction.
The technical specifications detail the construction methodology, requiring a 2-inch mill and tack coat application prior to cushion installation. Sections A-A and B-B provide cross-sectional views showing cushion heights ranging from 3.00 inches at the centerline tapering to 0.00 inches at the edges over a 6-foot width, with specific slope and elevation requirements documented. The document notes that all bidders must review supporting documentation and project details, with bids containing omissions from industry assumptions deemed non-responsive. Interested prime and subcontractors are required to indicate their bidding interest through the PennBid profile, which serves as the sole source of accurate bidding information. A questions and answers guide is available in the solicitation documents for clarification prior to bid submission.
