November 29, 2010

Quarry Visitor Center – Installation of the exterior window frames is underway and approximately fifty-percent complete. The window openings have been enclosed using a reinforced poly material.

Much of the roof membrane has been installed: the sloped section of the roof has been completely covered, although detail work remains; the flat section of the roof is 60 percent covered.

Rough installation of the fire sprinklers is nearly complete. The fire riser and domestic water lines were pressure tested, and everything passed. A new fire hydrant has also been installed and tested.

Stonework is nearly complete on the building. Because of the cold temperatures, areas where the masons are working have been covered and heated to allow the grouting to set properly.

Rough grading around the site continues.

The rough installation of most of the plumbing, electrical, and mechanical is complete.

Quarry Exhibit Hall – At the Quarry Exhibit Hall, there are several walls that need to be formed and poured, so much of the focus is on concrete work. A low retaining wall at Grid 3 has been completed. The retaining wall at Grid 2 is nearly complete. Two retaining walls between Grids 2 & 3 are complete, and the voids are being backfilled.

Lead paint abatement continues.

Quarry Visitor Center – In preparation for new asphalt pavement in the parking lot, work was underway on the subgrade and aggregate base, the foundation for the actual road.

Stonework is nearly complete on east and north sides of building and ongoing on the west and south sides.

The contractor cleaned the existing roof deck in preparation for new roofing and work on the new roof is expected to begin the week of November 15.

Quarry Exhibit Hall – Work continues on the foundation of the building. Grade beams and pile caps have been completed on seven out of the ten grids, and work on the other three is underway.

Both the pile caps and grade beams will help ensure a solid foundation, suitable for the unstable soils on which the Quarry Exhibit Hall was built. (Pile caps are reinforced concrete cast around a group of piles. They ensure that those piles act as a unit to support the column above. Grade beams, also reinforced concrete, connect the pile caps and provide additional support for the structure.)

Work continued on the support walls for the ramp that will serve as the main entrance to the building.

Although lead paint abatement is ongoing, the painters were on-site this week. They completed a coat of primer on the ceiling area above protective structure covering the quarry face and pressure washed the eaves to remove old birds’ nests.

November 8, 2010

Quarry Visitor Center - The rough electrical, plumbing, and insular radiant heat piping installation work is complete, as is the fire sprinkler system installation.

Grading for the new bus stop pavement is underway in the west parking lot.

The exterior stone work is nearly complete on the east and north sides of the building and continues on the west side. With autumn’s cooler temperatures, areas in of stonework-in-progress are being covered and heaters have been provided.

The visitor center roof is covered to resist moisture intrusion from wet weather and window openings are covered in preparation for interior heating.

The roofing material has been delivered and roofing work has begun.

Quarry Exhibit Hall – Forming and rebar installation is underway around the grids for the walls that will support the ramp that will serve as the main entrance to the building.

Lead paint abatement continues on the north side of the building.

The paint colors were reconsidered and, rather than the desert rose and turquoise from the 1950s, the park has decided to go with “earth tones” for the building.
