Attachment 0001 25-1-05 Vertical Mills Mounting Pads SOW (26-04-02).pdf

This document is a technical specification and engineering drawing set for concrete mounting pads at Rock Island Arsenal JMTC (Joint Munitions and Training Center).

The project involves the design and construction of vertical mill mounting pads in Building 208 at Rock Island Arsenal. Eight concrete mounting pad areas (numbered 1-8) are specified, with Areas 1-6 and Areas 7-8 categorized as new construction and existing concrete repair work respectively. The new concrete pads must meet a minimum compressive strength of 5000 PSI and be constructed with specific reinforcement requirements including #5 rebar mesh with 6"-8" spacing from top and bottom surfaces. Concrete thickness specifications vary: Areas 1-3, 5, and 6 require 18"-24" thickness, while Areas 4 and 7 require 12" thickness. The pads will be elevated level with existing surrounding concrete, maintaining no greater than 1/4-inch deviation across 10-foot spans. General notes specify contractor responsibilities including dust elimination during demolition, debris removal per local regulations, repair of any floor damage, proper concrete transportation (maximum 1.5-hour haul time at specified temperatures), and site cleanup upon completion. Construction activities will operate on a day shift for framing, tying rebar, and pouring, with demolition/jack hammering on second shift (2:30-11:00 PM) or Saturdays. Security requirements mandate background checks, security clearances, and FPCON compliance for all contractor and subcontractor personnel. The document includes detailed engineering drawings with mounting hole layouts, elevation plans, and specifications for expansion joints and surface preparation.
