The seven-acre MonteCedro Senior Living Community features new, villa-style senior living residential buildings, with the community space totaling close to 420,000 sq. ft. The complex includes 186 living units, a 90,000-sq.-ft. subterranean cast-in-place parking garage, memory care assisted living spaces, and four standalone buildings. It also includes a cocktail lounge, an art studio, chapel, movie theater, business center, library, performing arts/multipurpose auditorium, fitness center and pool. The site slopes 44 feet from north to south, so the buildings are arranged around shared courtyards, terraced to integrate buildings, walks, drives and service. 

All four senior living buildings will be licensed California Retirement Care Facilities for the Elderly, and the project will be completed in December 2015.

This is one of the most modular projects DPR has had the opportunity to work on. Typical for Southern California residences, the original concept for the structure was wood framing. However, as the project began, a recent update to the California Building Code stated that if combustible building materials were used—given the building height and nature of the occupancy—then the number of non-ambulatory and/or bedridden residents were restricted to the lower two levels. The owner did not want to place this restriction on their residents. Their goal is to provide a true “aging in place” environment so residents could choose to remain in their apartments and not have to move if they required more care and staff support. 

To remedy the code change as well as owner and end user needs, the team suggested using prefabricated light gauge structural frame (LGSF) panels for the four-structure, 331,350-sq.-ft. project, which saved time and resources. 

The LGSF system offered an option to prefabricate much of the project. Prefabrication is a manufacturing type of environment with repetitive processes and efficiencies. Within this controlled environment, the prefabrication process allowed greater precision and quality control versus building the panels in the field. The panels were delivered by 284 trucks. More than 3,200 wall panels and 1,300 floor panels (as well as the 2,000-plus trusses) were erected by two 65-ton rough terrain mobile cranes. Weighing less than 2,000 pounds each, the panels are uniform in shape and size, resulting in a highly efficient installation.

Only slightly more costly than wood, the 274,000-sq.-ft. LGSF system and use of prefabrication save an estimated $4 million and shaved four months from the schedule when compared to a non-prefabricated metal stud system.

BIM Features

By first building the project virtually using building information modeling (BIM), DPR coordinated closely with a team that included the architect, mechanical designer, plumbing designer and electrical designer. DPR played a large part early in the design of joist spanning, stud gauges, headers, and, most importantly, in the details that enable the panels to be prefabricated, shipped and erected.
