ADA-Compliant Curb Ramp and Detectable Warning Surface Installation

The contract involves the design and installation of ADA-compliant curb ramps featuring detectable warning surfaces, constructed using polymer composite or colored concrete in PCA Buff or Aztec Gold #827 finishes, ensuring full compliance with both federal ADA Accessibility Guidelines and California-specific accessibility standards. The work must meet all technical, safety, and regulatory requirements for public pedestrian access, with particular attention to slope, width, landing dimensions, and the integrity of tactile warnings to assist individuals with visual impairments. This is a subcontract opportunity issued by the City of Pasadena, California, with a response deadline of July 30, 2026. The North American Industry Classification System code is 238290, indicating it falls under other heavy and civil engineering construction activities. All work is to be performed within Pasadena, and the project demands precise adherence to material specifications and installation protocols to ensure long-term durability and regulatory compliance. Bidders are expected to demonstrate experience in accessible infrastructure projects and the ability to deliver high-quality, code-compliant curb ramp systems that integrate seamlessly into existing urban environments.
