About this file
This document is a construction plan for installing a vault toilet facility at the Marconi Site. The project requires construction of a new double vault toilet on a concrete pad with associated concrete walkway, crushed stone transition paths, accessible parking signage, and detectable warning surfaces. The concrete pad must be 4 inches thick with 4000 PSI air-entrained concrete and 6x6 W1.4xW1.4 wire fabric reinforcement, supported by a 4-inch compacted gravel subbase. The walkway specifications are identical to the pad requirements, while the crushed stone transition surface must be 4 feet wide and 4 inches deep, compacted to firm surface. A new 4x4 cedar sign post with accessible parking signage must be installed in a concrete base per specifications.
Field verification and layout requirements specify that the contractor must verify existing grades and elevations of the parking lot, existing asphalt walkway, and surrounding terrain. The design must achieve ADA-compliant accessible routes from parking to the vault toilet with cross-slopes not exceeding 2% and running slopes not exceeding 5% (1:20), except where site conditions require compliant ramp landings, along with positive drainage away from the toilet. The contractor is required to prepare a layout plan with spot-grade elevations showing proposed top-of-concrete elevations and submit it to the Contracting Officer's Representative (COR) prior to concrete placement. The modular double vault toilet must be installed per manufacturer instructions and MASSDEP permit requirements, with final slab layout and top-of-slab elevations coordinated with the COR. The contractor must also coordinate all work with the contracting officer to resolve conflicts with existing utilities, walkways, and parking areas.
