After 45 years and an increase in visitors, it was time for a large renovation of the Seaside Civic & Convention Center. The expansion added 19 percent more space for events, maintenance facilities and storage capacity totaling 55,000 square feet.

The project involved renovations and upgrades to ballrooms, offices, lighting, storage and plumbing. It also included a new lobby, a second plaza, a 35 percent expansion to the Necanicum Ballroom, new meeting spaces and several new entrances. The project was completed in several phases, and the building remained operational throughout the entire renovation process.

Keeping the convention center fully operational throughout construction was one of the largest challenges. The team worked closely with the fire marshall and other officials to ensure proper exits and access points were approved and safe for the community. As an example, the team built the staircase to be both safe and aesthetically pleasing and to minimize any disruption during paid events.

The project also involved improving and updating the efficiencies and safety of the building regarding structure, energy and electronic updates to modernize. The project team focused on sustainability strategies such as upgrades to the existing mechanical system, which increased energy efficiency.
