About this file
This document is a construction specification and drawing set for concrete mounting pads at Rock Island Arsenal Joint Manufacturing and Technology Center (RIA-JMTC) in Rock Island, Illinois. The project involves installation of new concrete mounting pads in Building 220 (B220) and its annex, organized into eight distinct work areas.
The scope of work includes demolition of existing concrete floors (4-8 inches thick) in Areas 1-5 and Area 8, installation of new 5000-PSI concrete mounting pads ranging from 24 inches thick in most areas to 16 inches thick in Area 8's confined basement tunnel space, and concrete repair and finishing work in Area 6 (approximately 4,500 square feet of existing concrete). Area 7 involves complete concrete removal, installation of tie-back supports with #8 rebar reinforcement spaced every 10 feet, and installation of new 4000-PSI concrete. All new concrete requires double-tied layers of #5 rebar mesh positioned 6 inches from top and bottom surfaces, with 3/4-inch expansion joint material (BASF Sonolastic SL-1 or equivalent) and ground rod installations. Contractor responsibilities include dust control using water during demolition, coordination of concrete delivery with truck mixers (maximum 1.5-hour haul time), provision of spotters for equipment movement, barricading of work areas, and complete worksite cleanup. Area 8 work requires confined space permits and specific safety protocols for the basement tunnel access hatch (23 inches tall by 24 inches wide). The contractor must comply with Rock Island Arsenal security requirements including AT Level I awareness training, background checks, RAMP security program participation, and iWATCH briefing for all personnel. Construction scheduling specifies demolition and jack-hammering on second shift (2:30 PM-11:00 PM) with framing, rebar tying, and pouring during day shift.
