NAVFAC Bldg 3235 Battery Area Upgrades

This project replaces the process ventilation systems in Zone 3 to correct deficiencies, replaces some HVAC systems and chilled water systems for Zones 2 and 3, replaces fire detection and suppression systems for Zones 1, 2 and 3, includes structural modifications to the test cells in Zone 3 to accommodate process ventilation upgrades. Due to the nature of the previous operations in Bldg 235 for destructive battery testing, the surfaces and air filters could be contaminated with residues. The contractor shall protect their personnel from potential contamination when disturbing any surfaces or filters in Zone 3 of Building 3235. These test cells have been designed to withstand sustained pressures ranging from 10 to 30 psig. The test cells are surrounded by occupied "runway areas that are used by personnel as workspace. In Zone 3, site personnel have witnessed gases from battery testing leaking from the supply and exhaust systems. This project replaces the process ventilation systems in Zone 3 to correct these deficiencies, replaces some HVAC systems and chilled water systems for Zones 2 and 3, replaces fire detection and suppression systems for Zones 1, 2 and 3, includes structural modifications to the test cells in Zone 3 to accommodate process ventilation upgrades. The estimated price range for this project is $1,000,000 to $5,000,000 Completion- 591 calendar days
