Excel Constructors Receives Capstone Award

Excel earned the Green Design award for construction of the
Sugar Creek Patrol and Fire Station.

Description: This 16,000 square foot project
was built on a contaminated site previously owned by British
Petroleum. Building on the grounds where an old oil refinery
stood created two particular challenges: venting toxic fumes
and creating a way to stabilize the building on unstable ground.
Strategy: Preventing petroleum fumes from
entering the building required a vapor-intrusion system
that captures petroleum fumes in an underground pipe system,
said Chris Bradley, Project Manager for Excel Constructors.
The unstable ground required that the engineer design a
system to drive piles into bedrockand pour a floating foundation.
"It basically floats on the soupy soil, and then the weight
is transferred to the bedrock through the steel pilings,"
Bradley said.
Environmental Challenges: Anyone working
on site during fresh excavations had to go through 40 hour
hazmat training. Safety was heavily monitored. If harmful
fume levels were unsafe, the site would have to be shut
down until those fumes had dissipated. "That was the biggest
challenge: getting it out of the ground and keeping with
the schedule when you never knew if you were going to be
shut down," Bradley said.
