RENOVA was selected by the United States Coast Guard (USCG) Civil Engineering Unit (CEU) Providence as the prime contractor to upgrade the hazardous material (HAZMAT) storage system at Station New Haven in New Haven, Connecticut. The existing arrangement consisted of three (3) storage lockers that were in disrepair, lacked up-to-date safety features, and did not meet the Station’s storage needs. Initially, the USCG proposed replacing the lockers with a single new building. Upon review of the initial design, RENOVA noted that the single building would have prohibitively high shipping costs and would not provide sufficient storage space.

RENOVA worked closely with a HAZMAT storage designer and fabricator and proposed the installation of two (2) new buildings, allowing for separate fire-rated storage space for flammable materials, additional organization, and reduced shipping costs. The design proposed by RENOVA included special features to suit the USCG’s needs, including interchangeable lock cores for customized security, corrosion-resistant materials suitable for the marine environment, and a 72-inch door to accommodate the existing waste oil tank and other larger equipment.

The USCG approved RENOVA’s proposed design and construction activities were initiated in August of 2023. RENOVA mobilized four (4) temporary HAZMAT containers to the site to ensure continuous storage for the client throughout construction. Once the temporary storage was energized, all materials were relocated, and the existing three (3) lockers were completely emptied, cleaned, disconnected, and transported offsite for recycling. Site preparation work done by RENOVA included saw-cutting and removal of concrete and asphalt, running new electrical service, excavating 215 tons of soil, installation of bollards, and forming and pouring two (2), 6”-thick concrete pads with 30”-thick haunch footings. All other disturbed surfaces surrounding the pads were restored with asphalt.

The two (2) new buildings were transported to the site and offloaded with a crane. Following placement, RENOVA energized the buildings, armed the fire suppression systems, and connected them to the USCG’s existing fire alarm mechanism. All materials were moved into the new buildings and the temporary storage was deenergized and demobilized. RENOVA finished the project within budget, with zero safety incidents, to the complete satisfaction of the client, and provided the USCG with a storage solution that offers security, longevity, safety, and functionality.
