About this file
This document package includes plans and specifications for an HVAC replacement project at a Veterans Affairs medical center building. The project scope involves replacing an existing split system air handling unit with a new exterior gas package unit, installing new ductwork, ceiling, electrical and mechanical room construction, and connecting a new gas line. The project is located at building B-182 of the Eugene J. Towbin Veterans Affairs Medical Center in North Little Rock, Arkansas. The specifications provide details on the demolition of existing HVAC equipment and ductwork, as well as the installation of new equipment, ductwork, diffusers, equipment pads, and insulation requirements. Construction is to take place during normal business hours and be completed within 90 days.
