Pearl Harbor Visitor Center
Pearl Harbor, Hawaii

The entry to some of Oahu’s major attractions and hallowed historic sites, the Pearl Harbor Visitor Center features educational and interpretive exhibits to commemorate the December 7, 1941 attack on Pearl Harbor. Open 362 days a year accommodating 1.5 million visitors annually, the Visitor Center demanded properly phased construction to keep the facility in operation and to protect the safety of those visitors. The Pearl Harbor Visitor Center seven-building complex features seven new structures of 17,750 SF within an open-air campus that houses state-of-the-art exhibits depicting the historical attack on Pearl Harbor. Facilities include ticketing offices for the combined Pearl Harbor Historical sites, concession space, book store/gift shop, education classrooms, exhibit space, theaters, restrooms, and administrative and support areas. Renovation of the theater building included permanently stabilizing the theater with a network of 200-feet deep pile clusters, pile caps, grade beams, and steel beams that tie into existing precast wall panels. Pile reinforcing was required to meet current seismic code. The project achieved LEED Gold certification.

Replace Typhoon Damaged Homes at North Tipalao, Phase I & II
Comnavmarians, Guam

This design-build project involved the demolition and replacement of existing homes. Our team managed the design process, resource constraints, streamlined the construction schedule and reduced project construction costs while maintaining quality by establishing our own Concrete Precast Operations on Guam. A total of 204 new homes were constructed for junior enlisted personnel and their families. The new buildings are three- and four-bedrooms, two baths duplexes consisting of five different floor plans, ranging from 1,450 SF to 1,640 SF. The new homes were constructed from precast concrete panels and equipped with Energy Star appliances, central air conditioning, granite counter tops, and storm shutters. The first Energy Star rated houses on Guam, the homes are designed to withstand 175 mph winds. Five percent of the total units were handicapped accessible. The project also provides tot lots, jogging paths, bus shelters, pavilions and common open space. Working from our precast plant, we cast precast walls, columns, and roof planks, and our team produced panels with integrated weld plates and a structural support system specifically designed to withstand 175mph winds to meet NAVFAC specifications.
