About this file

This document is a clarification memorandum regarding a federal construction contract for joint sealant replacement and pressure washing at a Veterans Affairs medical center. The contract requires amendments to the scope of work due to the discovery of an existing adjacent electrical upgrade project. Specifically, joint sealant replacement and pressure washing must be omitted from areas on the north, east, and south sides of Building 20 where electrical cable trays have been temporarily attached to the exterior precast concrete panels. The contractor must also provide temporary protection of the cable trays during pressure washing using waterproof tarps. The contracting officer is requested to issue an amendment to Solicitation Number 36C24223B0047 to clarify the omitted work areas due to the existing electrical cable trays.
