Sloped steel roof joists, structural steel, load bearing masonry, composite steel and concrete slab floor
system, braced frames for lateral, steel curtain wall, cast-in-place concrete grade beams, and screw piles make up the structural
To manage the various structural design components, we used software relatively new to the
industry which starts the model from CADD, applies the assigned vertical loads to individual members, designs the members
based on pre-determined criteria, generates the necessary seismic loads, models the lateral load resisting elements, and communicates
member sizes and reactions back to the working drawings.
On future projects with favorable geometry, we will use this software to reduce the engineer’s
analysis and design time, as a check, and to deliver construction documents faster. At the suggestion of the Contractor and
as a value engineering item after bidding, the conventional driven pipe piles were replaced by the newer technology of screw
piles approximately 60 feet deep to gravels. The screw piles, which we used for the first time on this project, reduced foundation
costs and improved the schedule significantly.
Although the appearance of the building is quite conventional, the analysis
method and the foundation system were very innovative and rewarding. Covering 61,000 SF in two levels, this pre-K-4 facility
contains classrooms, a gymnasium, stage/music room, full commercial kitchen, multi-purpose areas, and administrative offices.
