About this file
This document is a technical specification for platform access modifications related to solicitation RVKQ 25-0012 for Repair MAU Access Platform, dated 29 May 2026.
The specification requires design and installation of a hatch opening through the bottom of two existing platform structures to enable access for personnel and Modular Air Unit (MAU) filter replacement. The hatch opening shall be sized approximately 24 inches by 36 inches (2x3 feet) and positioned within the existing structural spacing occurring every 3 feet to accommodate MAU replacement filters measuring 24 inches by 24 inches by 2 inches, with adequate clearance for personnel passage. The design must remain within the confines of the existing platform structure. Additionally, the specification requires closing and sealing an existing side access point on each platform (identified by chain notation on the drawing) through welding structural supports to eliminate fall hazards, as this access feature is no longer applicable. The document includes a technical drawing showing the platform configuration with 1¼-inch steel checker plate, cross bracing details, and the location of the MUA unit, along with two photographs of the actual platform installations showing the overhead mounted equipment and structural framework.

RVKQ 25-0012 Repair MAU Access Platform
Bottom of Platform Access Drawing 29 May 2026
To access the bottom of each platform (there are two), the design shall remain within the confines of the existing platform structure. This means a hatch opening thru the bottom of platform structure would appear to have structural features every 3 feet. The hatch opening shall be within that spacing. This hatch opening might look like a 2x3ft opening (24” x 36” opening)
This specified opening is purposed to allow a person and MAU replacement filters to pass thru opening with adequate clarences. The hatch dimensions above are for guidance purposes but should be taken into consideration. Note: The MAU filters are sized at 24”x 24”x 2”.
Also, where each platform has an existing access side (shown below with label notating a chain) should be closed up by welding in supports to eliminate a fall hazard. Since this feature is not applicable, the access thru platform bottom is the new access point.
