The 36-year-old company installed the pilings that anchor the bridge to the sandstone cliff. The “micro-pilings” that D.J. Scheffler combined with a special high-strength cement grout have kept the bridge in place since it opened in 2007. Thanks in part to the pilings and the cement, the bridge has the capacity to bear 35,000 tons of weight and withstand winds up to 100 miles per hour.
“Everything about that project was challenging,” company owner and President Dale Scheffler said. “Drilling into a 3,000-foot sandstone cliff, withstanding those ferocious winds, and — above all — the sheer remoteness of the site that required us to haul all our equipment up 20 miles of dirt road.”
But for Scheffler and his specialized foundation drilling and slope repair company, such challenging projects are the bread and butter of the business. He doesn’t even consider the Skywalk project his most challenging.
“That honor goes to a bridge project we completed a few years back at Vandenberg Air Force Base where we had to put in 10-foot diameter pilings that went 100 feet deep,” he said. According to Scheffler, those pilings are the largest used for any infrastructure or building project on the West Coast.
A close runner-up was placing the foundation for a pier on Santa Rosa Island, one of the Channel Islands off the Santa Barbara coast. “Much of that work was done entirely over water,” he said.
Lure of difficult projects

He had previously founded a company that installed pools in residential properties — he was building the quintessential California suburban dream. One of the projects he took on was for a member of the automaker Ford family that involved drilling deep foundations. He had to call in a specialty drilling contractor.
“I discovered that’s what I really wanted to do,” he said.
Scheffler bought a rig and decided to focus on drilling foundations on the region’s plentiful hillside slopes. His first clients were mostly single-family homeowners. On some of those projects, he either worked solo or brought in a handful of day laborers.
His first office and equipment yard were in the City of Industry. A few years later, the company moved to nearby Pomona.
After a few years growing the business, Scheffler’s firm took on higher-end residential clientele with homes in Malibu or other exclusive communities that had to deal with hillside slopes. Today, this type of work comprises nearly one-third of the company’s business, including the building of new homes, putting in basements and making other alterations.
“We were the first company on the West Cost to use this CFA methodology, giving the client an environment where they can build a new structure,” Scheffler said.
Besides building on slopes, D.J. Scheffler also developed a specialty of stabilizing slopes that had recently collapsed in mudslides or landslides.
“Many contractors don’t do temporary shoring because it is risky,” Scheffler said. “That’s where (we) come in.”
The company will often bring in a geologist to assess the ground movement and outline the steps necessary to contain the movement and stabilize the slope.
In many cases, one of those steps is placing a barrier between a landslide and an adjacent home.
One such landslide project was in the University Hills neighborhood near Cal State Los Angeles.
According to Ralph Jeffery, owner of Encinitas-based Pacific Coast Land Consulting and a geologist consulting on the project, D.J. Scheffler & Nye drilled roughly 350 pilings into the slope to bolster its stability.
“They had to drill fast before the concrete set on the pins, and there was a lot of groundwater on this slide,” Jeffrey said. “A different company with lesser equipment would not have been able to do the work.”
During the work, Jeffery said he had to descend into the shafts drilled by D.J. Scheffler.
“I was the guy going down the hole, and I felt confident and safe in their hands,” he said. “I trusted them with my life and I could trust them to get the job done.”
Bigger development projects

One subcontractor who has worked alongside D.J. Scheffler on several of these projects over the past 20 years is Chuck Poss, president of Garden Grove-based Earth Construction & Mining.
Poss said D.J. Scheffler’s role on these projects has been to produce as much buildable space as possible.
Poss said one recent development project they worked on together in Pacific Palisades stood out for its challenges. The hillside property had been through a landslide in the 1970s and needed lots of shoring up and a retaining wall to keep the slope in place.
“The site was undevelopable for decades; there were complex soil and geotechnical issues,” he said.
According to Poss, D.J. Scheffler had to put in pilings that extended down “to considerable depth.”
The project, now called One Coast, was completed in 2018 and consists of 53 luxury condos.
But Scheffler said that in the last couple of years, the firm has pulled back to focus primarily on Southern California, especially since the Covid-19 pandemic struck.
“Covid really slowed down the work,” he said. “There was a little less work, but also, Covid forced projects to take longer.”
Not only did following Covid protocols inhibit the work on site, but Scheffler said the pandemic forced delays among its vendors, affecting the delivery of concrete, steel and other materials that the firm uses in its projects.
The logjams seem to be loosening up now. “Our backlog has been growing again,” he said.
Looking ahead, Scheffler said he has no plans to sell the company in the near future. He said that when he does retire, he intends to pass the reins on to his younger business partner, Mark Nye.
“One of the reasons I brought Mark on five years ago was to take over when I retire,” he said.
