2015 Design Award Winner: Harry H. Edwards Industry Advancement Award

Comstock Graduate Housing

This year’s Harry H. Edwards award winner is a shining example of how precast concrete can bring durability, performance, and effi ciency to any project.

All of these benefi ts came together in the new Comstock graduate student housing at Stanford University, where the owners faced se-rious time and cost challenges. The project included replacing nine low-rise, two-story buildings that provided 79 beds, with four new buildings to accommodate more than fi ve times as many students.

To meet the needs of the students in the short allotted schedule, the designers chose precast concrete solution rather than wood, says Mark Palmer of Clark Pacifi c, the precast concrete producer for the project. “With the speed of erection, the general contrac-tor was able to deliver the student housing within one school year, getting students in quicker, and allowing the university to start bringing in revenue earlier.”

2015 Design Award Winner: Best International Building Structure

Latter Day Saints Tijuana Temple

The Church of Latter Day Saints (LDS) temple in Tijuana Mexico is more than just a religious structure. Church leaders wanted it to be a powerful statement to the people of Tijuana, says Wallace Cooper, of CRSA, the architect for the project. “There was a conscientious effort to create a temple that said: ‘you are incredibly important to our church.’”

The temple design went through three iterations, with each successive set of drawings pushing the designers to go further, and to create a more vi-sually striking structure that would stand out against the crowded Tijuana backdrop. “It had to be something that was truly outstanding,” he says.

Precast concrete was chosen early on in the process because it was the only material that could deliver the soaring design and sophisticated de-tails that the church desired. “With each iteration, the precast pieces became more complicated and intricate in detail and jointing,” he says.

2015 Design Award Winner: Best Hybrid Parking Structure

UC Davis Medical CenterParking Structure III

UC Davis Medical Center Parking Structure III is a winner of both the 2015 Design Award for best hybrid parking structure and a 2014 recipient of the honorable mention award.

When you build anything in California, safety and performance are always first in mind. When leaders of the University of California at Davis (UCD) Medical Center began planning for a new six-level parking garage to accommodate 1200 cars, they knew it would have to meet the most rig-orous seismic requirements. Administrators also wanted a structure that reflected the hospital’s reputation as one of the leading medical facilities in the country—and it had to adhere to a tight timeline and budget.

Going with a precast concrete design enabled them to achieve all of these goals. “The use of precast concrete minimized the impact of the structure, while reducing the actual on-site duration of the project,” says Genaro Morales, director of architectural design for Watry Design in San Jose, Calif. “Cast-in-place would have required substantially more con-struction activity for forming and placement of the concrete and rebar.”

2015 Design Award Winner: Best Parking Structure Facade

Pomona College South CampusParking Structure

What do you do when the parking garage that you need to build takes up valuable park space on a crowded college campus? Build a full-sized soccer field on the roof. This was just one of the many innovative design solutions that the project incorporated into this LEED platinum–rated three-story parking structure built on the Pomona College South Cam-pus in Claremont, Calif.

“From the beginning the owner was very concerned about losing an existing soccer/Lacrosse field,” says Brent Dezember, of StructureCast, the precast concrete producer for the project. They also wanted the structure to blend into the natural surroundings as well as with the older stately buildings that dot the campus. “Using a precast concrete facade, enabled them to address all of these issues,” he says.

2015 Design Award Winner: Best Government/Public Building

The Broad Museum

The new Broad Museum, in Los Angeles, Calif., looks like a white wedding veil sparkling against the blue California sky. Indeed, the structure has been dubbed “the veil and the vault” by designers who created the unique facade to wrap around the museum’s two key spaces: the public exhibition space and the archive/storage space that will support the foundation’s extensive lending activities.

The vault is enveloped on all sides by an airy, cellular exo-skeleton structure made up of 2500 glass-fiber-reinforced concrete (GFRC) panels and 650 tons of steel lifts that span across the block-long gallery; it provides filtered natural daylight. “The process of making the formwork for the uniquely shaped panels was a key factor in the success of this GFRC application,” says David Pakshong of Gensler, the executive architect on the project. Choos-ing a product with the demands for hundreds of different unique curved shapes for the exterior skin was a big chal-lenge for the design team. Creating hundreds of conical light openings for the building and replicating the front oculus from a parabolic curve would need a product that was flexible and versatile to adapt to this design shape.

2015 Design Award Honorable Mention: Bridge with a Main Span Up to 75 Feet

Fort Goff Creek Bridge

In 2010, responding to a, existing state law that re-quires unimpaired passage for all anadromous fish at stream crossings, Caltrans prepared a priority list for replacement projects. The existing Forth Goff Creek Bridge, which was a 15 feet (4.6 m) diameter structural steel plate culvert, no longer met code. Indeed, the old design received the lowest rating for fish passage be-cause the drop-off from end of the culvert to the creek water level prevented salmon from spawning further upstream.

In response, Caltrans decided to replace the 60-year-old pipe culvert, with a new 60 feet (18 m) long, single-span, precast, prestressed concrete voided slab bridge. To minimize disruption, they went with an accelerated bridge construction method that enabled them to de-liver the project in just 78 working days.

2015 Design Award Honorable Mention: Non-highway Bridge

Loma Linda UniversityPedestrian Bridge

Time was of the essence for this project to build a new pedestrian bridge that could safely carry people from a parking garage to the hospital at Loma Linda University in California. The owners did not want to disrupt traffic any more than was necessary on the busy campus, so they went with a precast concrete solution. By choosing a precast concrete, the contractors were able to limit closure of the street to just one day on order to place the new 8 ft (2.4 m) wide pedestrian walkway—emblazoned with the words “Loma Linda University Health”—over Campus Street, which serves as the entrance to the Loma Linda hospital emergency room.

2015 Design Award Honorable Mention: Custom Solution

L.A. Live Marriott Courtyard & Residence Inn

Designers of this 23-story, mixed-use hotel in bustling down-town Los Angeles, Calif., originally envisioned the structure with a metal panel and glass curtain wall facade system. But when that solution failed to fit their budget and high- perfor-mance demands, the owner and design-build team turned to a local precast concrete producer to come up with a better alter-native. The facade had to be cost-effective, durable, and able to meet continuous insulation requirements, all while comple-menting the aesthetic design of the structure.

2015 Design Award Winner: Best Healthcare/Medical Structure

University of California at San Francisco MedicalCenter at Mission Bay

The University of California at San Francisco (UCSF) Medical Center at Mission Bay in San Francisco is recognized around the world for its innovative patient care, advanced technology, and pioneering research. When the owners decided to expand its facilities at the Mission Bay site to house its highly regarded cancer, children’s, and women’s programs, they wanted to ensure the building reflected its leading-edge identity—within a reasonable budget. “Cost was one of the biggest challenges on this project,” says Helen Fehr, executive principal of Rutherford + Chekene, the engineer on the project. “We were charged with designing a high-quality, cutting-edge hospital at a below normally accepted cost.”

Fehr’s team considered a variety of design options, and determined that precast concrete was the best choice. “Precast came in as a very economical, durable, and attractive option,” she says.

2015 Design Award Winner: Best Rehabilitated Bridge

North Torrey PinesRoad Bridge

The north Torrey Pines Road Bridge in Del Mar, Calif., is a sweep-ing 550 feet (168 meters) long structure that curves along the Pa-cific Coast, crossing an active railroad line. The original structure was built in 1933; and after standing for more than seven decades in the harsh salt air, it was suffering from severe corrosion.

The bridge had been classified as structurally and seismically de-ficient, and analyses showed that the majority of the bents and abutments needed to be rehabilitated. Even if the corrosion had been mitigated, the existing columns would not be able to handle large seismic demands without catastrophic failure, says Keith Gaz-away, senior engineer for Kleinfelder, the engineer for the project.

With the goal of preserving this historic structure, a specialized rehabilitation strategy was developed that would allow for minimal change to the visual character of the bridge while providing a far

more seismically stable design. That would not be easy, Gazaway says. “Developing a constructible retrofit strategy that satisfied the complex seismic demands without affecting the bridge’s appear-ance and historic eligibility was our biggest challenge.”

They chose a precast concrete system to meet the needs of the project because precast concrete would deliver the high-perfor-mance seismic and durability they needed, with the design flex-ibility to maintain the historic look and feel of the original bridge. “The use of precast allowed the contractor to demolish and re-place the historic structure in a sensitive marine environment in close proximity to a very active rail line,” Gazaway says.
