A raised floor system is just one of many features of the new home for the Marine Corps League’s Detachment 708. Located north of Tampa, Florida, in Spring Hill, the 5,000 square-foot building serves a multitude of purposes for members of the detachment, its related women’s auxiliary and youth organizations. For the Marine veterans, the raised floor design allows easy renovation or floor plan changes over the life of the building.
“In light commercial construction, raised wood platform foundations can easily accommodate changes,” says Bill Tucker, executive director, Florida Building Materials Association. “For example, a change in occupancy from an attorney’s office to a doctor’s clinic can be easily accomplished. Moving walls and plumbing is simple.” This T-shaped raised floor system started with a concrete-block stem wall. Treated sill plates of 2×8 pressure-treated Southern Pine were installed atop the entire wall. Inside the stem wall, concrete block piers support glued-laminated beams (5-1/2″x15-7/8″) and engineered parallel-chord floor trusses (16″o.c.) for the main room of the building. Trusses span 40 feet; top and bottom chords are 2×4 MSR Southern Pine 2400f-2.0E. Sub-flooring is 3/4″ T&G plywood. All wall framing is pressure treated with borates for long-term resistance to decay and termite attack.
Proper connections for high-wind considerations are also incorporated for winds up to 110 miles per hour. Exterior walls use 2×6 material; interior walls are framed with 2×4 lumber. This project was constructed in accordance with the Standard Building Code and is rated for A-2 occupancy.
