Commercial General ContractorsRoger Nelson

Midstate Construction Corp., 1180 Holm Road, Ste. A, Petaluma 94954; 707-762-3200; www.midstateconstruction.com; ’07 revenue: $92 million; 75 employees

John Winblad started Midstate in 1935, but Roger Nelson, 62, has been owner and president of the North Bay’s second-largest commercial general contractor since 1977.

Hot project types for Midstate are retail, hospitality, market-rate and affordable multifamily housing, commercial and industrial. Top current projects are Santa Rosa Junior College’s $30 million Bertolini Student Services Center, Marin Catholic High School’s $11 million Pope John Paul II Student Education Center in Kentfield and the college’s $8 million Pepperwood Preserve laboratory and classroom.

Construction cost inflation and environmental awareness are forcing builders to be flexible and innovative, according to Mr. Nelson. Part of the innovation includes having many on staff become LEED-accredited professionals, including Mr. Nelson.

“The sum of the cost and environmental challenges will lead the construction industry to build better buildings with longer-term cost efficiencies,” he said.

Rick Grossmann

Wright Contracting, P.O. Box 1270, Santa Rosa 95402; 707-528-1172; www.wrightcontracting.com; ’07 revenue: $92 million; 35 employees

Paul Wright started the company in 1953, and it passed to Jay and Michael Wright in 1981. They passed management to Rick Grossmann, 49, in 2005 when he was chief estimator and had been with the company for 15 years. He earned an undergraduate construction management degree from Chico State University in 1983.

Areas of specialty are large public projects such as schools as well as wineries, office buildings, multifamily complexes, industrial facilities and hotels. Key current jobs are project management for the Petaluma campus and main campus student services center for Santa Rosa Junior College, collectively $103 million, and as designer-builder for Sonoma State University’s $48 million Tuscany Village student housing in Rohnert Park.

Troubles in residential real estate have heightened bid competition on public and commercial jobs, but tightened lending standards have stalled private projects that had been reinvigorated by lower bids, according to Mr. Grossmann. He worries that some of the eagerness of companies to win bids could lead to industry contraction.

David James

Ledcor Construction, 466 Devlin Rd., Napa 94558; 707-257-5321; www.ledcor.com; ’07 revenue: $85 million (North Bay); 35 Napa employees

The Napa office focuses on hospitality, light industrial and light commercial projects, some of which recently, namely the Meritage and Verasa Napa Valley hotels, have been among the largest in Napa Valley.

Top current projects are The Riverfront, a $49 million mixed-use building in downtown Napa and valley wineries Dana Estate and Futo.

Jim Nolan

Napa Pacific Inc. dba Nolan Construction, 1804 Soscol Ave., Ste. 203, Napa 94559; 707-963-3222; www.jnc-construction.com; ’07 revenue: $62 million; 80 employees

Trained in architecture, Jim Nolan is founder of Nolan Construction, which he started in 1986 after five years as a construction manager for Newton Vineyard and two years as a hotel project engineer in French Polynesia. Nolan Construction merged with Hearn Construction of Vacaville in 2005.

The hospitality, assisted-living and medical markets are active, according to Mr. Nolan. “We believe growth in the retail and office markets will be slow for the next few years, but we have continued to receive steady work from these sectors,” he said.

Top projects under construction are the $8 million phase 2 of Vino Bello with 66 assisted-living units in Napa, $7.4 million 48-unit Sunrise Assisted Living facility in Carmichael and a $7.2 million Holiday Inn Express hotel in American Canyon.

Del Nordby, 45, is president and Craig Nordby, 37, is vice president of a multifaceted company that has carved out leading positions in commercial, wine cave and custom-home construction. Diversification has helped Nordby weather economic cycles.

“We believe that contraction within the construction industry is nearly at an end, and we will begin a gradual increase in construction activity over the next two years,” Craig Nordby said.

Projects coming out of the ground now chiefly are the 14,000-square-foot Merriam Winery in Windsor, 16,000-square-foot Meadow Club in Fairfax and Homeward Bound of Marin’s 24,000-square-foot The Next Key job-training center in Novato.

Their father, Wendell Nordby, started the company in 1978, and the company passed to the next generation earlier in this decade.

Mike Ghilotti

Ghilotti Bros. Inc., 525 Jacoby St., San Rafael 94901; 415-454-7011; www.ghilottibros.com; $55 million (North Bay), $94 million (companywide); 275 employees

Mike Ghilotti, 46, has been president since 2000 of the company his grandfather James Ghilotti started in 1914. In the past two years, revenue for Ghilotti Bros. has grown 22 percent and 28 percent, and the company has expanded to the East Bay.

He foresees the flow of heavy highway and nonresidential projects to continue, barring the diversion of transportation funds to cover the $15 billion state budget deficit, and potential for increasing work in residential developments as soon as this month.

“Overall, we’re very strong on the forecast for the last of 2008 and the first half of 2009,” he said.

However, Mr. Ghilotti sees many of his older generation of workers retiring in the next three to five years, so the company has been increasing mentorship and English education programs to prepare for the transition.

Mike A. Smith

Argonaut Constructors, 1236 Central Ave., Santa Rosa 95401; 707-542-4862; www.argonautconstructors.com; ’07 revenue: $35 million (North Bay), $47 million (companywide); 175 employees

Summit Electric handles high-voltage electrical contracting; Summit Electronic Systems does design and installation of home and business low-voltage equipment and networks, such as home theaters and lighting controls; and Summit Electrical Service does maintenance and service calls.

Mr. Dashiell said that low-voltage solutions have been a driver for company revenue growth in the past several years.

“A lot of our clients are not tech-savvy,” Mr. Dashiell said. “We take out-of-the-box components and connect them to easy-to-use controllers.”

Plumbing ContractorsLes Peterson

Peterson Mechanical, 21819 E. Eighth St., Sonoma 95476; 707-938-8481; www.petersonmechanical.com; ’07 revenue: $30.05 million; 128 employees

Les Peterson, 58, is president and CEO, rising to operation of the company 25 years ago. Granduncle Ed Peterson started the company in 1915.

About 45 percent of the company’s business is piping in projects such as the Green Music Center, Kaiser Permanente’s five-story medical center addition in Santa Rosa and Memorial Hospital’s new emergency department.

Forty-four percent is heating and air-conditioning and the rest is service.

Tom LeDuc

LeDuc & Dexter Plumbing, 2833 Dowd Drive, Ste. A, Santa Rosa 95407; 707-575-1500; www.leducanddexterplumbing.com; ’07 revenue: $8.2 million; 50 employees

President and CEO Tom LeDuc, 60, has weathered three recessions since he partnered with Vice President and COO Art Dexter in 1983, yet they continually positioned the company to survive and thrive. The company grew to 50 employees and $5 million in revenue before the recession of 1991 forced the company to contract to 20 workers.

After that slump, the company diversified from working on mostly residential new construction with the addition of the Super Service Plumbing business and the acquisition of a commercial design-build plumbing company in 1994 and Northern Fire Protection a year later. That helped revenue to not dip as appreciably with the recession of 2001.

The company then grew to 75 employees and $13.2 million in 2005 at the height of the Sonoma County building boom. The dramatic slowdown in home construction reduced revenue to $12.5 million in 2006 and $8.2 million last year, so Mr. LeDuc started tightening the corporate belt, laying off field and administrative workers, stopping donations and freezing wages and much capital spending. He budgeted for $7 million this year.

“We expect to see new home construction to remain weak for at least another 12 to 18 months,” he said. “Commercial construction remains strong in our sector.”

Solar ContractorsDan Thompson

SPG Solar, 20 Leveroni Court, Novato 94949; 415-883-7657; www.spgsolar.com; ’07 revenue: $56 million; 166 employees

President and CEO Dan Thompson, 51, started the company in 2001 with just $1.5 million in revenue that year. This year, projected revenue is $100 million.

At the end of last year, the company had 127 employees. The company has expanded for the fifth time and has nine locations. In 2005 he split off the photovoltaic system production as Thompson Technology Industries.

“While we may not be able to control economic factors such as inflation and the cost of raw materials and components, we have been able to optimize our installation practices through our experience over the years and develop products through TTI that drive down labor time and costs,” Mr. Thompson said. “Our goal is to make solar cost-effective.”

John Schaeffer

Real Goods Solar, 13771 S. Highway 101, Hopland 95449; 888-507-2561; www.realgoods.com; ’07 revenue: $32.7 million; 90 employees

John Schaeffer, 58, founded Real Goods as a solar and sustainable-lifestyle products company in 1978 and oversees the solar installation, catalog and Internet sales business. Though trained as an anthropologist at U.C. Berkeley, he became an early promoter of home photovoltaic power systems, starting in Hopland and opening a third store in Sebastopol in 1982.

Colorado-based Gaiam bought Real Goods in 2000 and took Real Goods Solar public early this year. In November, Gaiam added dominant southern California solar installer Carlson Solar and 6-year-old Marin Solar early this year. All three companies account for photovoltaic installations on more than 2,400 homes, mostly in Marin and Sonoma counties.

Commercial solar installations may be hurt if federal tax credits aren’t renewed at year end, but systems for upscale homes, which don’t get much of a break, will continue, according to Mr. Schaeffer. The company’s equity-based financing has helped keep jobs flowing.

“I think the solar industry will continue to grow at 40 percent to 50 percent a year for next three to five years,” he said.

Bill Stewart

Solarcraft, 285 Bel Marin Keys Blvd., Novato 94949; 415-382-7717; www.solarcraft.com; ’07 revenue: $10.6 million; 35 employees

President Bill Stewart, 56, and Dennis Nuttman started the company in 1984 and survived the expiration shortly thereafter of incentives for installations. Since 2004 the company has grown fourfold and recently expanded its headquarters.

“With utility rates continuing to rise and the fact that a system can be financed for less than the average monthly utility bill, interest in solar continues to grow despite the slowing economy,” he said.

John Parry

Solar Works, 130 Petaluma Ave., Sebastopol 95472; 707-829-8282; www.solarworksca.com; ’07 revenue: $5.8 million; 16 employees

Trained in physics at U.C. Irvine, CEO John Parry, 52, founded the company in 1986 by purchasing the customer list from a retiring solar water-heater installer. The company installs residential as well as municipal and commercial solar-power systems. He has been a consultant on the state exam for the solar contractor’s license and a lecturer on renewable energy.

Competing with large installers with buying power to offer low prices is a challenge for independent installers, and a looming end to public incentives isn’t helping, according to Mr. Parry.

“Solar will not be less expensive in the near future,” he said.

Linda Novy purchased the company in 1976 and was CEO until it transitioned to employee ownership in 2003.

Daniel Rasmussen

Paul Irwin, 51, started working at the company in 1982 following a business management internship in 1979. Today he is president of a multifaceted company that expanded beyond what Joe Bell started in a barn in 1945. Revenue soared from $25.5 million in 2006 because of a gain in market share, according to Mr. Irwin.

“The housing downturn has thrown more contractors into the commercial markets driving prices down,” Mr. Irwin said. “To continue being successful in today’s market, value-added services will be the key.”

Innovations include computer server room-cooling products.

Sargon Michael

Allied Heating & Air Conditioning, 12 De Luca Place, San Rafael 94901; 415-459-5232; www.alliedhvac.com
