Attachment D Pre-Proposal Inquiry Form.xlsx

This is a Pre-Proposal Inquiry (PPI) submission form containing contractor questions and requests for clarification regarding solicitation N4008525R0144 for a generator installation project at Building 31 for NMCI. The inquiries span multiple technical and operational areas related to the proposed work.

The inquiries address critical specification gaps and ambiguities across several disciplines. Structural concerns include clarification on automatic transfer switch inclusion, vertical rebar detailing (hook requirements), rebar mat configuration (single versus double mat), and conflicting foundation specifications referencing both 12-inch thick mat foundations and 18-inch elevated slabs. Foundation and site work questions seek confirmation on PVC drain tie-in requirements, manhole cover specifications and load ratings, soil bearing pressure verification requirements (1,500 psf assumed), and brick veneer flashing details. Operational and traffic management inquiries request confirmation regarding roadway blockage and parking space utilization near Building 30, outage scheduling restrictions (after-hours/weekend only), maximum allowable outage durations, temporary generator requirements for shipyard operations continuity, and acceptability of water-filled barriers in lieu of concrete jersey barriers. Additional clarifications address cross-hatch paint application scope (approximately 50 linear feet in front of generator platform), electrical storage stanchion responsibility (government-furnished versus contractor-furnished) with cable rack sizing and finish specifications, and integral fuel tank sizing parameters relative to the 100-percent load for 24-hour operational requirement. These inquiries indicate the contractor's need for refined technical specifications and operational parameters before finalizing proposal responses.
