About this file

This is a Design Revision document issued by NAVFAC Mid-Atlantic for a federal construction project managed by ROICC – Norfolk. The revision addresses Building SP-312, a chiller replacement project (eProjects Work Order Number 1624308), dated 4 March 2026. The design revision was issued in response to Class J&A No. ML-25-30 and affects one mechanical drawing.

The revision modifies NAVFAC Drawing No. 12,911,899 (Sheet M-701, titled "Controls") by adding a paragraph to the Sequence of Operation section. The modification establishes mandatory control vendor requirements, specifying that acceptable control vendors must be either Automated Logic Corporation (ALC) WebCTRL or Johnson Controls International (JCI) Metasys, with no exceptions permitted. This requirement restricts the contractor's selection of building automation control systems to these two specified vendors only.
