We are proud to announce the completion of the design-build restoration to a building recently damaged by a neighbor’s fire.
The client took the opportunity, since much of the roof structure was damaged, to replace the entire roof with four-ply built-up roof system. Six skylights were replaced and two were added, increasing the natural light throughout the warehouse. Additionally, a self-flashing galvanized steel roof access hatch was installed.

The exterior of this building was damaged by a fire in the neighbor's yard. A structural engineer determined one panel needed to be replaced entirely.

The rebar and pickup and brace points are being wired into the framing of the two concrete tilt-up panels.
Rebar & Points
The tilt-up panels are being poured together. After the concrete cures for the first seven days, they can be raised and put into place.

A crane raises the panels and moves them into place.

The crane raises the panels off of the casting slab by its pickup points and puts it into place with help from men inside using guide wires.

The second tilt up panel is raised and put into place.

The second panel is put into place and both panels are made plumb and secured with the brace bars.

The two panels that replaced the one damaged panel are now ready to be sacked and painted.

New CMU wall and two new panels (with higher parapet wall by City Code) are finished.

A 3-ton heat pump unit was replaced and it was relocated onto a factory curb to minimize leak potential.
During reroofing is the best time for a volunteer seismic retrofit of the building and that is precisely what our client opted for. We also replaced the tilt-up panel that had been compromised structurally (it bowed outward) with two new concrete tilt-up panels.
