Clark Construction ‘Tops Out’ Aztec Stadium With the rubble of Qualcomm Stadium piled high about 150 yds. away, the construction of San Diego State’s new football stadium reached a major milestone on July 14, 2021.

Construction crews from Clark Construction performed a traditional “topping-out” ceremony at Aztec Stadium by hoisting the final steel beam into place at the top of one of the scoreboard frames. The beam was signed by guests and had a symbolic evergreen tree on it.

Crews separated out rebar and other debris and ground the concrete rubble into small pieces that will be used for fill around the site.

Clark Construction Group joined SDSU leaders, city officials and distinguished guests to celebrate topping out the multi-use stadium — one of San Diego’s most highlyanticipated projects. The topping out ceremony marks the completion of structural steel

Construction Begins On Massive Airport Metro Project The Los Angeles County Metropolitan Transportation Authority (Metro) has begun construction on the $898.6-million Airport Metro Connector Project that will directly connect the county’s transit system to Los Angeles International Airport (LAX), providing a reliable, fast and convenient connection for passengers and airport-area employees.

“The Airport Metro Connector is a historic step toward reimagining how travelers experience our airport — a turning point that will be a source of jobs and economic growth, reduce congestion, and help our airport realize its potential as a world-class gateway to Los Angeles,” said Los Angeles Mayor and Metro Board Chair Eric Garcetti.

Metro’s Airport Metro Connector The Airport Metro Connector Project (AMC) is the ninth station along the 8.5-mi.

Crenshaw/LAX Line currently under construction. Metro’s Crenshaw/LAX Project is one of 12 transit projects funded by Measure R, the half-cent sales tax approved by Los Angeles County voters in 2008.

The new transport hub, planned for completion in 2024, includes platforms to access Metro light rail trains and an expansive 16bay bus plaza that will serve Metro and other municipal bus operators in the region. Metro said the AMC will serve as a true “Multi-

Modal Transit Gateway” to LAX by connecting travelers directly with the Automated People Mover (APM) project presently being built at the airport, which in turn connects directly with passenger terminals.

LAX’s Automated People Mover The APM, slated to be fully operational in 2023, is a 2.25-mi. elevated electric train system that will deliver passengers and employees between LAX and new facilities for transit, car rental and offsite parking.

Los Angeles World Airports (LAWA) said the $2 billion APM project is “a historic investment in Los Angeles’ emerging businesses and workforce.” Noting that, “more than $585 million has been identified for local, small or disabled veteran-owned businesses,” LAWA said the project “will create more than 2,000 construction jobs, with 30 percent of those opportunities being reserved for residents of Los Angeles as well as highly impacted communities near LAX.” “Everyone traveling to or from LAX should have access to modern, reliable public transportation that gets them to their destination on time,” added Garcetti.  The $2 billion APM project is “a historic investment in Los Angeles’ emerging businesses and workforce.”

Three Calif. Companies Partner to Launch TimberQuest Three San Francisco Bay Area construction industry companies have partnered to launch TimberQuest, an innovative, sustainable and highly efficient solution for building costeffective, prefabricated “mass timber” classrooms for the California K-12 and community college markets.

The partnership between XL Construction, Milpitas, with Aedis Architects, San Jose and Daedalus Structural Engineering, based in Saratoga, combines the organizations' unique expertise in 21st century learning environments with mass timber design and construction.

Building a Better School Environment Panel by Panel The basic building block of TimberQuest construction is precision-machined, cross-laminated timber (CLT) that is available in large format structural slabs. It is strong, yet lightweight, fire resistant and leaves these structures with rich exposed wood finishes.

"Where one may think building with wood is bad for the environment, the opposite is true," said Matt Larson, preconstruction director of XL Construction. "Mass Timber construction, including the TimberQuest approach, supports responsible forest management, including the reduction of wildfires and protection of biodiversity. It also promotes rural economic development by expanding the market for sustainable forest products."

The carbon benefit of timber construction is well docu-

mented and has a two-fold benefit. First, utilization of a wood structure in lieu of steel or concrete has a significantly lower embodied carbon footprint, reducing the carbon footprint due to construction by 40 to 60 percent. Second, wood effectively sequesters carbon within the timber structure, storing it for the life of the structure and any subsequent reuse.

TimberQuest employs cross-laminated timber to create prefabricated wall and roof panels offsite that are erected and installed at school construction sites, enabling buildings to be constructed in significantly shorter timeframes. The structures are pre-checked and approved by California's Division of the State Architect (DSA), so they can be used for any public school or community college project in California, reducing permitting time from six months to a single day.

Most buildings can be constructed in 10 weeks over a summer break.

In addition to expedited project completion, TimberQuest buildings offer a healthy and eco-friendly environment.

Their interiors feature the warmth and airiness of a tall wood ceiling, extensive natural lighting and an openness that contrasts with the sterile, box-like modular buildings often seen on many school campuses. TimberQuest structures are highquality and permanent — with life expectancies of 50 years or more — with more usable floor space than traditional modular buildings. Yet, they can be delivered quickly, due to the pre-approved design as well as rapid factory fabrication

and onsite erection, offering public and private schools the best of all worlds, the company said.

"The partnership between XL Construction, Aedis and Daedalus enables us to think holistically to solve design, permitting, procurement, prefabrication and installation issues," said Steve Winslow, senior vice president of XL Construction. "TimberQuest provides a superior environment for students to learn and teachers to teach."

"There are three ancient Roman principles expressed in a true piece of architecture: strength, practicality and beauty.

This collaboration epitomizes the integration of these precepts into a flexible, durable, economical and environmentally responsible solution that addresses most schools' needs," said John Diffenderfer, president of Aedis Architects.

"Daedalus is excited to be a part of this collaboration which advances mass timber construction by developing a school buildings 'kit-of-parts' for over-the-counter permitting," said Doug Robertson, president of Daedalus Structural Engineering. "By integrating cross-laminated timber panels with insulation, architectural finishes and other buildings systems in shop fabrication, we are able to deliver preassembled wall and roof panels to any school site for immediate erection and completion of sustainable, attractive and durable public school classroom buildings in record time.”

Clark spent the first several months of the project prepping the site and driving more than 2,000 stone columns below grade. The columns, which range from 2-to-3 ft. in diameter and measure up to 36 ft. long, provided soil stabilization and will help support the stadium’s structural load by transferring the weight of the structure from the foundations.
