Description
The US Navy is seeking a design-builder to perform repairs on Building 530 at the Dam Neck Annex in Virginia Beach, VA. The project involves renovating the natatorium and exterior coastal environment, which are severely corrosive. The design-builder must select and utilize materials that are inherently resistant to trichloramine vapor, chloride-laden condensation, coastal salt spray, and continuous high humidity. The project requires the installation of a new HVAC system, including supply air ductwork, return air ductwork, and general exhaust ductwork. The design-builder must adhere to strict material baselines and prohibitions, including the use of non-permeable, antimicrobial fabric for the supply air ductwork and aluminum with a factory-applied epoxy/phenolic coating for the return air ductwork.
Some key requirements and considerations for this project include:
• The design-builder must ensure that all materials and systems are designed and installed to withstand the corrosive environment and meet the required 15-20 year operational lifecycle.
• The design-builder must provide and install an engineered, continuous-fabric ductwork system for the overhead supply air distribution within the natatorium envelope.
• The design-builder must ensure that all return air ductwork exposed within the pool room is constructed of aluminum with a factory-applied epoxy or phenolic coating.
• The design-builder must provide a material selection matrix that summarizes the mandatory material selections and strict prohibitions for the various HVAC subsystems within the natatorium envelope.
