MARINE STRUCTURES

There are some projects recognized as a state-of-the-art of using precast concrete used in their construction method. It can be mentioned some of them; for examples: The Ocean Going and the Inter-island Harbors in Surabaya, and the Breakwater/Pier Structure at U.S. Naval Station Everett in Washington which received the 1998 PCI Design for the best Miscellaneous Structure. Precast/prestressed concrete provided a cost-effective solution that is both functional and aesthetic for marine/naval facility situated in a difficult and environmentally sensitive coastal area. It can be adapted to similar structural applications in aggressive marine environments. Another important reason for the success of those projects is that high quality precast/prestressed concrete products, manufactured under controlled "factory conditions", were delivered by the producers/contractors to the site on schedule.
The use of precast/prestressed concrete for the marine structures provided for the following benefits: (1) giving an aesthetically pleasing structure, (2) low in maintenance for highly functional structure, (3) limited environmental impact, (4) durability in an aggressive marine environment, (4) a fast track construction schedule, (5) a cost effective in an integrated structural system.
