Webcor Builders first update for 301 mission ....
301 MISSION STREET, SAN FRANCISCO, CA
Project is a mixed use facility consisting of a 58 story tower and an 11 story midrise tower connected by a 3 level podium, over 5 stories of underground parking. Total area is approximately 1,150,000 square feet.
UPDATE
We currently have 2 tower cranes planned 2 double man lifts for the high rise and 1 single car for the mid rise.
Webcor concrete has planned for a Peri self climbing elevator core system for the high rise and 2 sets of flying forms. We are currently planning to hand set the forms for the mid-rise (gang forms, etc, but no flyers or
self erecting core systems)
The garage is an internally braced soil cement slurry wall system with soldier piles 5’ OC and the High Rise foundation is a soil cement slurry wall system with soldier piles 5’ OC with a few rakers and the balance of the hole supported with a single row of tiebacks. Both of these perimeter wall systems are augured 3’ diameter overlapping holes creating a continuous wall.
We are currently showing a 5 day floor cycle for the construction of the high rise, and a 5 day per floor cycle for the curtain Wall and all interior finishes
