This is a technical specification document for ADA Detectable Warning Surface installation, issued by Bristol Borough in Bucks County, Pennsylvania, as part of the 2026 CDBG Curb Ramp Program. The project requires installation of ADA/PennDOT compliant detectable warning surfaces at specified locations within the borough. The work involves polymer composite detectable warning tiles composed of epoxy polymers with aluminum oxide particles in truncated domes, manufactured by a PennDOT Bulletin 15 approved manufacturer. Tiles must be Brick Red in color with dimensions of 24 inches nominal width, 0.1875 inches face thickness with ±5 percent tolerance, and 0.5 percent maximum edge warpage. Installation shall be performed according to manufacturer recommendations in a manner that does not create tripping hazards. Tiles must be protected against damage during the construction period and are guaranteed in writing for five years from final completion, including coverage for defective work, breakage, deformation, and loosening.

Contractors selected for this work must demonstrate a minimum of five years of experience with tile installations and submit qualifications documentation including a list of similar projects and superintendent resumes for approval. The installer's qualifications must be accepted before work commences. All materials must be certified to meet or exceed designated specifications and comply with ADA and PennDOT regulations. Installation costs and pricing terms are not specified in this technical specification document, as pricing would be submitted separately in the contractor's bid proposal. The project is funded through Community Development Block Grant (CDBG) resources and requires compliance with federal labor standards including Davis-Bacon wage rates, performance and payment bonds, and various contractor certifications as outlined in the overall bid solicitation.
