The quick-release bolts and angled clips mean that marina operators can work more efficiently and have fewer obstacles that sometimes lead to equipment or boat damage.

Behold the latest PEMB marina drystack storage building at Harbour Isle (now called One Particular Harbour Margaritaville) near Anna Maria Island, on the gulf coast of Florida. From a simple concept, I designed the building for both aesthetics and function. I worked with the manufacturer every step of the way, and managed the erection, concrete, plumbing, electrical and sprinkler systems. This included implementing customized changes in the foundation and fire sprinkler design for optimum efficiency, resulting in substantial savings for the client.
