The building construction is being managed in 4 sections, labeled counter-clockwise from the Northwest corner as sections A, B, C, and D. Teams of specialty contractors move from section to section. Each team completes tasks that are preliminary to tasks to be completed by a following team.
Each section of the building is in a different stage of construction, but work on all sections proceeds simultaneously. At this time, the sections are being completed in reverse order.
Sections A and B will be "slab-on-grade," while the other sections are suspended over a 3 foot 6 inch tall crawl space.
Section B includes the round atrium at the South side of the building.
Grade beams for section A are complete and are currently being backfilled.
Curved forms for the atrium are being set in section B.
The most of the first floor deck is complete for section C. Deck pans are being removed from underneath the completed deck by way of the crawl space. Columns are also being poured in section C.
Forms for the elevated beam deck of section D are being constructed.
Whenever workers are more than 6 feet about grade, they must wear a safety harness and be
"tied-off" 100% of the time. Workers attach their harness to safety cables using large snap hooks.
Each harness has two of the large hooks, enabling workers to move from structure to structure while always being tied-off.
There are nearly 80 workers on site today:
- Westbrook (forms): 30
- Western Placers (steel): 12
- Encompass (electrical): 12
- Hensel Phelps (grade beams, concrete pouring, field engineers): 20
