Quarry Visitor Center–The exterior framers have finished the majority of their work and most of the interior framing is also complete.
The new pedestrian bridge, connecting the parking lot and visitor center, was set this week. This is a bridge with an interesting history: it used to be a railcar! This recycled railcar is one of the sustainable features/green technologies that will be factored into the LEED (Leadership in Energy and Environmental Design) certification for the new visitor center.
It’s time to think about paint colors, but we’re waiting to receive the sheet metal samples before finalizing color choices. The bridge will be a terra cotta color, and other exposed metal will be dark beige. The underside of the space frame in the exterior seating area will be a lighter color to reflect the light and brighten up the area.
Quarry Exhibit Hall–Concrete work for the new foundation continues. On one of the grids, the grade beam reinforcement was located roughly an inch or two too low because of over-excavation and placement of the rebar; additional #4 bars were added to the top of the pour to remedy to remedy the situation. The contractor is ensuring that excavation is to grade and correct rebar placement in the remaining grids.
Lead paint abatement continues, but is slow going, and the structural steel installation has to wait on the lead abatement.
Desert rose paint will be used for the exhibit hall.
