Building Renovations: Phase 2
Friday, February 26, 2010

The building renovations, which began in early October, are progressing quickly. The construction crew has gutted the building, removed outdated light fixtures, pulled the carpeting, and nixed all asbestos. The second (and longest) phase of the renovations, seismic upgrades, started in October and is really cruising now. Phase two consists of installing reinforcement bracing throughout the building and enclosing one of the old staircases to place a strengthening beam.

Builders started out marking the floors of each level where the buckling restrained brace, BRBs or cross beams, will be installed. These beams are part of the seismic upgrades that strengthen the building in the event of an earthquake. The beams are installed from the floor of the sub-basement to the top of the roof, with one set of beams on each of the four building sides. Most of the beams will be visible inside the building after construction is finished.
Spray paint marks the area for the cross beams. The round hole goes from the ceiling to the basement.
After the cross beams are installed, we will move onto general renovations with light fixtures, putting the ceiling back in place and -- of course -- installing exhibits for our opening!
