Hybrid steel structures can bring their own complexities and the San Pedro Apartments was no exception. With HSS, PACO Steel, and cold-form steel, this was uncharted territory for these highly-capable contractors.

Our experience in light gauge steel and structural HSS allowed us to work hand-in-hand with the subcontractors to provide the calculations, fabrication drawings and construction sequencing that was required to move forward.

Due to the height of the structure, OSHA required the subcontractor to carry a construction sequencing plan, and to provide further support, we also supplied the subcontractor with color-coded drawings, and an animated 3D model on top of the traditional shop drawings.

More About the Building

The San Pedro Apartments will be affordable housing that consists of 135 units on six floors with an outdoor deck on the sixth floor, a garden area, and a social service and community space. The structure has also been designed to LEED Platinum green standards and will feature a living roof and greenhouse, solar PV, and water efficient fixtures.

Over the years Zenith Engineers has completed hundreds of shoring designs, working on notable projects like the roof of the Apple Campus and the Adaptive Reuse project “Powerhouse Science Center”. Our experience has helped reinforce that our designs keep workers safe while working on the building, whether it’s holding up the roof or bracing the exterior to keep the walls from collapsing inside.

Caltrans is improving roadway infrastructure in California by widening and strengthening its overpass system. This makes the original overpass defunct and requires the demolition of the older infrastructure.

Caltrans is challenged with removing the original bridge without disturbing the flow of traffic, the solution is to piece-meal the demo, weakening the bridge until the entire overpass can be removed overnight. Zenith Engineers was tasked with assessing the structural capacity of the bridge to determine the maximum size of the excavator that can remove the deck portion the quickest.

LADBS has issued Ordinance 183893, addressing safety hazards of non-ductile concrete buildings in downtown Los Angeles. Non-ductile concrete construction was a popular building method for schools and commercial structures due to its large spans and open spaces, but their weak columns and walls poses threats of life and property in serious seismic activity.

Zenith Engineers explains the first step in the process of checking a building’s compliance before designing the seismic retrofit. Watch to the very end to learn how Zenith’s President reveals the thorough way to check compliance.
