Headquarters Administration Building Project

July 22, 2023 –  A 100-ft section of the pedestrian skybridge spanning the width of Ellis Avenue was installed. Remaining sections will be installed to complete the bridge to connect the new Headquarters Building to OC San’s Plant No. 1. Below are a couple of videos put together by OC San and HDR, the design consultant.

December 2, 2022 – Mass timber is an engineered wood. It is strong, fire resistant, aesthetically pleasing, reduces carbon footprint, and works alongside other materials as a structural element. Check out video of the last major piece of mass timber being installed.

October 20, 2022 – A “topping off” is a common tradition in construction to commemorate the completion of a building’s structure, or the placement of the final steel beam. The last large structural steel beam was recently placed, “topping off” the new Headquarters Building.

November 2020 – In preparation of the project site, existing vacant buildings were demolished last Fall 2020. Check out the video to learn more about the demolition and the future Headquarters Building.

And just like that, the buildings are gone. Check out the time-lapse video of the buildings going down.
