About this file
This document is a special notice for qualifications requesting SF-330 submissions from architectural and engineering firms for a project to replace an existing campus primary substation. Firms are requested to submit SF-330 packages by July 12, 2021 for consideration. The project involves providing A/E design services including drawings, specifications, cost estimates and construction period administration for replacing the primary substation at the VA Medical Center located at 830 Chalkstone Avenue in Providence, Rhode Island. The construction value is estimated to be over $10 million. This is a total small business set-aside for SDVOSB firms under NAICS code 541330. Submissions will be evaluated based on professional qualifications, specialized experience, past performance, capacity, location, and experience in construction period services. The selected firm will be required to negotiate a fixed price rate proposal for the design services.
