Whitefish Central School

The new space includes a library, a vo-tech lab, a band room, a choir room, and of course classrooms and administrative offices. The library is a one-story section, and the classroom wings are two stories. The floors are framed of steel beams that are designed as composite members working with the concrete topping slab. The roof is framed with steel joist girders, steel beams and steel bar joists. The walls are mostly light gauge metal studs that in-fill the steel frame, although the band and choir rooms have concrete masonry elements to reduce sound attenuation. The lateral force resisting system is mostly concentrically braced frames and concrete masonry shear walls. The foundation is conventional concrete walls and footings with some concrete grade beams to resist overturning forces. The remodeled space will modernize the historic Auditorium wing, which currently holds classrooms and office space as well as the Auditorium and 52-foot tall Fly Loft. The structural elements of the historic wing include concrete foundation walls, un-reinforced brick bearing walls, wood-framed floors and roofs with some steel beams and columns. The structural upgrades include steel portal frames to support new openings in the existing concrete and brick walls, new wood floor framing elements, concrete masonry vaults, and some in-fill framing of existing floor and wall openings.

This building provides 94,000 square feet of space for middle school students. It includes a 42-foot tall gymnasium, a media room, a technology lab, a cafeteria, and of course classrooms and administrative offices. The classroom and offices wings are two stories and the gymnasium portion of the building is one story with mezzanine levels for additional seating. The floors are framed of steel beams that are designed as composite members working with the concrete topping slab. The roof is framed with steel beams and steel bar joists. The walls are mostly light gauge metal studs that in-fill the steel frame, although the gym walls are concrete masonry. The lateral force resisting system is mostly concentrically braced frames and concrete masonry shear walls. The foundation is conventional concrete walls and footings with some concrete grade beams to resist overturning forces.

Occupational Trades - FVCC

p1000145_145_145.jpg p9260030.jpg pa230054.jpg

This is a new one-story classroom building for trades such as welding, wood carpentry, automotive repair, and other occupations. The building concept is to express a very thin roof profile with large cantilever- up to 23 feet. In addition, the top 6-feet of all exterior walls are translucent panels to allow an abundance of natural light to filter into the building. The walls are discontinuous at a horizontal joint 19-feet above the floor slab. The CMU walls are designed as free-standing cantilevers from the concrete footings, which created a condition where no shoring was required. The roof diaphragm loads are transferred behind the translucent panels down to the CMU walls with steel diagonal bracing. The roof framing system is custom-designed steel framing with a maximum clear span of 66-feet. The interior is totally column free.

Arts & Technology - FVCC

The building requirements of multiple roof levels and large open rooms interspersed with typical smaller classroom layouts required that the structural design accommodate large spans at the roof and an open floor plan at the meeting room/lobby/gallery. Both the upper and lower roof is constructed of steel bar joists spanning up to 48-feet and supporting the suspended catwalk over the theater. Steel braced frames throughout the building supplement concrete shear walls for lateral loads. A large site built truss along the gallery and open lobby supports both the roof break and suspends the upper gallery over the meeting room. The full truss is 15-feet deep and 108-feet long, with a longest open span of 62-feet and cantilevers of 6 & 20-feet on either end. In order to better integrate the truss with the construction timeline and reduce the costs associated with craning and bracing a large truss, columns were installed at the lower level and the truss was built in place.

South Gate Mall Offices

img_1229_fix.jpg

This building is new construction of a five-story office building with a foundation footprint of 80 feet x 130 feet. It provides over 62,000 square feet of office space (including the basement). The main level is 15 feet tall and the remaining floors are 13.5 feet tall each. The floor framing is steel and concrete composite beams and girders. The roof framing is steel joists with a steel roof deck. The lateral load resisting system is concrete shear walls. The exterior walls are light gage steel stud framing. Brick veneer clads the main level, dryvit is used on the next three floors, and curtain walls are used on the fifth floor. The main level is a commercial bank, so assembly load is used in design.
