Salt Lake Community College Applied Technology Center

Summarize the project's program, features and achievements?

This was a re-construction of building that burned down at the community college. Although this building is not large it is very detailed and technical with existing buildings on all sides creating very tight site logistics. The shape of the building had several corners and interior walls, so our casting area was very limited. To accommodate casting the 87 panels we had two strategically placed casting slabs that could get reused several times. the building had to get stood in 5 different raises. To further complicate the site logistics there was an existing underground utility tunnel that ran across the only access point to the site and through the building. this tunnel had to be reshored and steel plated. this further limited our ability to maneuver the crane around the site.

The panels are a non-composite sandwich panel with an exposed concrete form liner Finish. some of the panels were only insulated on the top which required us to build a false platform to cast them on. some panels required 4 castings in order to complete the panel. One for the slab/ casting bed, the false platform, the architectural wyth, then the structural back. The panels had several integrated beam pockets that had to be precisely placed.

There were areas of polished slab that were left out. this created areas where there was not a slab to brace the interior partially insulated panels to. we could not use piers as the area needed to be clear for crane and equipment, so we had to have several downside brace inserts and attach the braces after the panel was picked.

Several of the building corners were designed as can't liver/ flag panels. we added a bottom and a false leg to the panels to assist in the erecting processes and to support them temporarily until the structural steel was in place.

With the crew's close attention to all the details and coordination's amongst other trades on site these challenges were able to all be navigated to provide a beautify timeless building to be enjoyed by generations.

What obstacles were overcome related to the schedule, budget, program, specification, site, etc. on this project?

We initially had figured 7 raises but that was going to take too much time on the schedule. so we reconfigured the casting areas in order to fit more panels on it. and were able to reduce the raises to 5. we were able to offset the added cost by the savings on the crane mobilizations.

There were areas of the slab that were to be polished concrete. these areas were either left out or planned to be removed and replaced after the panels were stood.

Please communicate any engineering complexities or unique features of the panel design for this project?
