Project engineer and developer explain how switching to wood framing made a California apartment complex pencil out

 

In this new video, APA's Karyn Beebe, PE, talks to developer Barbara Monroy and project engineer Amir Deihimi, who explain how the Santa Barbara Apartments were value-engineered to address excessive building material costs.

Located in Rialto, California, an area with significant seismic loads, construction of the complex had stalled due to prohibitive framing and material expenses. Monroy's search for alternative methods and materials led her to Deihimi of Core Structure, Inc., for more affordable engineering solutions.

A switch to I-joist compatible glulam, double-sided wood structural panel portal frames, and shear walls using Force Transfer Around Openings (FTAO) analysis got the project back in the black while addressing the seismic loads.

Adding up the savings realized through replacing steel shear walls with wood and using economical glulam beams, "I think the developer, Barbara Monroy, ended up getting her seventh building for free," says Deihimi.

"Having to redesign this project was a tough pill to swallow when you've already paid for it once. But in analyzing and calculating all the numbers, it was well worth it," said Monroy.

APA Case Study: Santa Barbara ApartmentsWhen framing estimates for construction of an a 120-unit apartment complex in Rialto, California, came in high, developer Barbara Monroy of BM Investments didn't give up. "Rental demand is picking up and values have started to climb," said Monroy. The original project design presented several challenges: the foundation design included expensive grade beams; few of the floor plans stacked, which created a complicated framing plan; and it included costly prefabricated steel shear wall frames surrounding each garage. On the advice of her framing contractor, Monroy took the project to Amir Deihimi, PE, of Core Structure, Inc. Core re-engineered the project, substituting glulam for other engineered wood and converting the steel shear wall frames at the garages to wood structural panel portal frames to get the project back on budget.
