July 27 & August 3, 2010
Quarry Visitor Center – Internal data and electrical underground conduit work is nearly complete. The internal underground sewer installation is also complete.
The west abutment wall is formed and concrete will be poured this week. The slab-on-grade and sub-grade are prepped. The northeast and northwest corners were poured, and three additional pours are scheduled for later this week and next. The first pour was very large; subsequent pours will be reduced in size to ensure quality.
Bridge abutment and slab-on-grade concrete inspections are on-going, as are the electrical underground inspections.
Quarry Exhibit Hall – Window abatement work continues. The north and west walls have been completed and the south wall should be complete this week.
The verification pile test took place last week and it performed well. The three proof piles are complete, and three production piles are complete. Proof pile testing will begin soon.

Internal data and electrical conduit work continued. The plumbing installation under the slab began. Backfilling began this week for the multi-purpose room and exhibit area.
Quarry Exhibit Hall – The waterproofing layer under the tile in the restrooms tested negative for ACM. General demolition continued. The gantry crane was removed last week.
