CO NP BLCA 10(1) South Rim Drive Plans.pdf

This file appears to be the plans and specifications document for the South Rim Drive Improvement project, a Request for Quote solicitation issued by the Department of Transportation Federal Highway Administration (FHWA) on behalf of the National Park Service (NPS). The project, numbered CO NP BLCA 10(1), addresses an immediate safety requirement to restore roadside protection along South Rim Drive following wildfire damage, with the objective of removing remaining hazards and installing modern, crash-tested safety barriers prior to peak visitor seasons.

The scope of work requires contractors to provide all labor, materials, equipment, and supervision for guardrail removal, site preparation, and installation across twelve distinct locations along South Rim Drive. Primary work elements include selective boulder removal and dispersal in accordance with park cultural and aesthetic boundaries, minor grading and shoulder stabilization, post-hole excavation at designated locations, and specialized guardrail procurement and installation featuring weathered-look steel finishes with Natina stain coatings. Contractors must also provide comprehensive traffic control services, including active one-lane closures and flagging operations to maintain safety for park staff and visitors during construction. Prospective bidders should note that specialized weathered-look guardrail steel and required aesthetic coatings carry extended procurement lead times of up to eight weeks, plus additional time for material curing periods, which impacts the overall contract duration and ordering timelines.
