Unfortunately, for 16 action-packed rides, a midway, and two restaurants on a deck pier now littered with storm damage, an abandoned hotel, and a concrete pier with added structural decay. The owner decided to demolish the hotel and structurally restore the concrete pier before installing any amusement rides, the entertainment midway, or restaurants. They hired the engineering firm of Stanley, Spurling & Hamilton from Houston, TX, to assess the pier and begin a preliminary design to structur- ally restore it. Considering the semi-tropical marine environment that included constant wave action, harsh UV exposure, airborne chlorides, and potential hurricanes, the accelerated deterioration and harsh conditions needed to be addressed with every engineering design and construction step. Little or no maintenance over the 70-year life of the pier has resulted in exposed reinforcing steel with accelerated corrosion and concrete spalling at piles, beams, joists, and reflective overhead flat plates.
