Frame
for the future
D.A.
Whitacre Construction Inc. started as a residential general
contractor in 1978 and has evolved into a specialized framing
contractor for commercial and industrial projects. Attention to
detail and adding value keeps the company in work.
After
one year in college, Don Whitacre decided construction was his
calling. In 1978, he opted for a hammer instead of a backpack and
hasn’t looked back since.
Whitacre,
president and CEO of D.A. Whitacre Construction Inc., in El Cajon,
California, started as an apprentice with a Colorado contractor
doing ground-up construction jobs. After three years, he took a side
trip of sorts – to Antarctica – to do construction there and to
figure out what he really wanted to do with his life.
After
his eight-month stint in the frozen tundra, he returned to his
native area in San Diego and started pouring concrete foundations
and framing residential homes.
Over
the years, his business, which he operates with his brother Bill and
wife Vicki, has changed dramatically. Today’s projects involve
intensive, tightly scheduled commercial and industrial jobs that
require more than a pneumatic nailer and a circular saw to complete.
The firm employs more than 300 people, working on many prestigious
projects in the San Diego area, ranging from award-winning SeaWorld
exhibits to the Arco Olympic Training Center.
The
firm’s work consists of 30 percent roof and floor structures for
tilt-up buildings, 50 percent commercial, multi-story residential,
church and assisted living centers, 10 percent commercial renovation
work and 10 percent public projects.
Whitacre
believes the company’s success stems from its ability to work
closely with general contractors and as important, designers and
engineers to complete projects on time and at best cost.
Commercial
and industrial framing projects require more organization and
attention to detail than residential framing work, says Whitacre,
and he believes the company’s success lies in its ability to add
value at the engineering phase of the project.
“Although
we are a subcontractor on commercial and industrial jobs, we often
work as closely with the engineers as the general contractor
does,” he says.
“Rough
framers are rarely called in on the design phase of a project, but
we often work with design engineers to find the most cost-effective
way of doing things. For example, engineers ask us which is the best
type of structural and seismic hold-down to use in multi-story
buildings. We have helped them understand that the lowest-cost item
may be the most labor-intensive to install. Lowest cost is not
always the best cost.”
Eye
on safe work practices
Whitacre’s
first interest is in crew safety, and fall protection continues to
get greater emphasis. Under new California OSHA rules, a fall
protection plan must be implemented to protect workers. The new
regulation allows the agency to implement a multi-employer citation
where all contractors on the jobsite with workers exposed to hazards
can be fined. “If a jobsite gets cited for a fall hazard or
accident, the contractor that created the hazard, subcontractors
with workers exposed to the hazard and the general contractor, which
is the controlling contractor, can all be fined. It behooves us to
have a complete fall protection program on the site,” says
Whitacre.
Increasingly,
Whitacre says contractors are addressing fall protection at the
front end of the project. “It used to be that everyone would chip
in to cover it as construction continued. Now it’s planned for
under the general contractor up-front,” he says.
D.A.
Whitacre workers go through a training program if they will work at
heights greater than 7’. “They must be certified to work off the
deck,” Whitacre says. Workers purchase their own safety harnesses
at a substantial discount through Whitacre’s supplier. “We want
them to have a financial stake in the equipment, but not so much
that it’s a financial burden.”
D.A.
Whitacre’s enforcement policy for fall protection and other safety
violations is straightforward and fair. “We have a series of
increasingly serious citations for workers. The first offense is a
verbal warning; second is a written warning; third is a day off
without pay, and the final step is dismissal,” Whitacre says.
“For
us to be successful, safety is our No. 1 priority, followed by
schedule and profit. We find that most injuries happen when workers
feel the pressure of a schedule and cut corners on safety. If we can
plan correctly so workers aren’t rushed beyond their limits,
safety becomes a much more manageable issue.”
Project
showcase: Rebuilding Hotel del Coronado luxury from the inside out
Renovating
a five-story century-old building can bring on distinct challenges.
Keeping the facility operational throughout the process adds layers
of complexity to an already difficult project.
When
D.A. Whitacre worked with general contractor Swinerton Builders to
renovate the 116-year-old luxury Hotel del Coronado, they knew they
would face these challenges, plus many more as the project
progressed.
As
the framing contractor on the recently completed $21 million
project, its job was to structurally rebuild this wood, five-story,
389-room Victorian hotel from the inside out.
“From
a subcontractor point of view, a renovation job is more risky. It
depends on how well the project is managed. On new construction, you
may see 25 to 50 change orders. On the Hotel del project, we saw
nearly 250 change orders. To accomplish the job with that many
change orders, it takes good problem-solving skills from the
owner’s representative, general contractor, architect, engineer
and subcontractors. It really takes a partnership
philosophy to make it work,” he says.
The
hotel’s foundation is built on sandy Coronado Island which is just
west of San Diego. Settling over the years has taken its toll.
“The building was in good shape but there is hardly a square or
plumb wall in the place,” says Kip Brandt, D.A. Whitacre’s
framing foreman on the project. “Trying to square up the walls
would be impossible and would ruin the fine woodwork throughout the
building. As we started demolition, we worked closely with the
structural engineer who stayed onsite throughout the project. Some
of the situations were impossible to predict until we got into the
work. Remodeling over the years caused their own sets of problems.
We were constantly figuring out ways to fix problems we
uncovered,” Brandt says.
To
stabilize the building, the foundation was excavated and reinforced
with buttress walls and grade beams. A steel frame was built into
the 13,500 sq. ft. Crown Room, which has a 33'-high ceiling covered
with tongue-and-groove, rib-vaulted pine paneling. The steel
relieves the pressure of the wide spans, which was slowly pushing
the walls out. The Grand Ballroom was renovated in the same way.
Installing
the steel frame in the expansive Crown Room had its own challenges.
The roof was entirely removed and over 3,500 pieces of the beautiful
wood paneling had to be numbered and removed piece by piece. Due to
space constraints, the steel frame was assembled offsite, then
installed using a 180-ton crane with a 195' boom. A 52.5-ton HVAC
unit was also installed before the roof was put back in place. Only
then was the restored paneling put back in place just as it had been
before the renovation.
In
other parts of the hotel, the floors were pulled up, structural
beams were installed to reinforce and tie the building together from
the foundation to the roof, then resheathed and refinished to match
the hotel’s Victorian style. “This was done on every floor. We
encountered some beautiful wood; we found 8"x16" beams 40'
long without any knots,” he says.
To
match the old lumber’s dimensions, crews used rough lumber and any
salvaged wood from remodeled areas. Over 250,000 bd. ft. of new
lumber and 4,000 cu. yd. of concrete were used in the upgrade.
In
basement shopping areas and other key locations, steel moment frames
and plywood shear diaphragms tie the building together to meet
seismic requirements.
To
attach the building’s frame to the beefed-up foundation, the crews
had to work in very tight quarters, installing universal foundation
plates that fastened the side of the sill plate to the side of the
foundation. “We were working in the bowels of the building in some
very tight areas. The Simpson plates made the work possible,” he
says.
“We
had no laydown area on the site, so materials had to come off the
truck right onto the job. With only one construction elevator on the
outside of the building, all materials had to come into the building
through it. We worked closely with suppliers to time deliveries on
an as-needed basis,” he says.
Throughout
the upgrade, the hotel remained open. “We could start work only
after 8 a.m. to minimize disturbing guests. Every day, we adjusted
our schedule to accommodate events taking place at the hotel. Plus,
we had to stay on schedule to keep the amount of time areas would be
out of service to a bare minimum,” recalls Brandt.
Today,
the renovation is finished and by Brandt’s estimates, the Hotel
Del will last another 100 years.
Project
showcase: City Walk no walk in the park
D.A.
Whitacre has a lead role in the development of City Walk, a
five-story, city-block residential project in the heart of downtown
San Diego. The all wood-frame complex will provide 109 high-end
living spaces to help meet the growing demand for downtown housing.
D.A. Whitacre crews are completing the rough framing work.
“On
this job, it’s all logistics. This is a project going up without
any staging area on site,” says Jeremy Vitale, jobsite foreman.
“We must closely coordinate deliveries so material comes off the
truck and right to the spot where it’s needed. We even work with
vendors so the material comes in on the trucks staged in the order
we need them.” A tower crane makes precise material placement
possible and efficient.
Because
of the tight space, Vitale gets daily material deliveries, as
opposed to other jobs where materials arrive weekly or all at once.
“The schedule is a challenge. You must think at least a week in
advance and make sure the crews are on schedule,” he says.
The
luxury condominium is being built in five sections, with the first
section nearing completion. “This project has 17 different floor
plans and no section is like another section. You must watch the
plans closely and stay on top of every step,” he says.
The
project uses all TJI joists and laminate beams. Studs used on the
first two floors are engineered lumber. “We need the laminated
studs because of the strength needed to hold up the five floors
above,” he says. They routinely cut the laminates with a chain saw
or a 16" radial-arm saw with a carbide-tipped blade.
“We’ve
been using the new Paslode Positive Placement nail guns to fasten
the straps and hardware to the laminates,” he says. The tool’s
nose probe accurately locates the strap or hardware hole and guides
the fastener as it drives it into the workpiece. It shoots
heat-treated nails that are less likely to bend and ricochet,
especially in laminates.
