Honnold Construction Management provided complete construction management services on the 777 Alameda project  which involved the seismic retrofit and core and shell build-out of an existing, historic, circa 1922, 4-story, 220,000 SF structure and 1 level, 44,000 SF basement in Downtown Los Angeles.  It included a simultaneous 88,000 SF tenant improvement on the 3rd and 4th Floors.  A new roof deck with a view of the city and support facilities were added.  The site work includes new parking lots, landscaping and new site utilities. The demolition, retrofit, and build out were a complete top down project.

Original freight elevators and motors were removed, as well as 7 existing freight elevators. Three of the existing elevator locations were transformed into new structural steel stairs while the rest of the existing elevator shafts were infilled.  Two new shafts were cut into the existing concrete decks for two new traction elevators. All existing interior walls were demolished.  Parts of the MEPF systems were gutted and redesigned, some were restored and reused. New rooftop mechanical systems were installed to feed the new tenant spaces.

A new ramp to the basement was created to accommodate the new basement level parking area and equipment.  Footings were dug out, grade beams were poured to bridge between the existing footings; some footings were demolished and new foundations were dug, shored and poured.

Two main interior latitudinal seismic components (100’ long) were formed and poured along 2 interior column lines.  These were tied to 6 bays on the exterior frame of the building.  A total of four new reinforced concrete moment frames were attached to the existing exterior facades, to complete the new seismic system.
