Corman has an 11-core safety training class requirement for
managers, engineers, superintendents and foremen catered to the
transportation construction industry, including CPR, first aid, fall
protection, excavation, rigging/signaling, manlift scissor/articulating,
scaffolding, confined space, OSHA 30-hour, crane safety and
guidelines for OSHA Inspection.
While the advancements in the industry are impressive,
attracting and retaining dedicated and talented employees in all
trades – at all levels – remains a big challenge.
“Even with increasing wages, there are not many up and coming
individuals interested in pursuing a career in the foundation
or construction industry. There is a stigma with many thinking
the profession suffers from a lack of sophistication. With constant,
major advances in technology, this is clearly not the case.
As a group, we are not funneling this vision towards today and
tomorrow’s high school and college students. Changes need to
be made as our industry presents opportunities and promise for
tomorrow’s leaders.”
Notable projects
Corman has been involved in hundreds – if not thousands – of
projects over its vast history. While all of them are notable for different
reasons, Cox mentions two recent projects, the first one being
the Main Pumping Station Diversions, Division I in Washington,
D.C., which was completed this summer.
This DC Water | Clean Rivers design-build project provides
control and consolidation of flow coming from combined sewer
overflow structures and is immediately north of the Main and O
Street Pumping Station. It is comprised of a 100-foot long belowgrade
surge tank, two sewage diversion structures, flow channels,
vent and odor control facilities and internal flow elements inside an
existing 100-foot deep tunnel shaft.
“We designed most of the excavation support, including
48-inch diameter secant piles and a combination king pile/sheet
pile system with three levels of internal bracing,” said Cox. “There
was also a 72-inch diameter FRP sewer pipe excavated under an
active arch sewer inside a liner plate tunnel.”
Two reinforced concrete diversion structures were constructed
atop active 100-year-old arch sewers (16 feet and 12 feet wide).
Excavations for these structures were 25 to 30 feet deep.
“The diversion chambers take rising stormwater overflows
over a series of weirs and into cast-in place concrete channels leading
into a 100-foot deep shaft and tunnel for treatment at the DC
Water Blue Plains Wastewater Treatment Plant. Existing utilities,
including water and electric services, were relocated and protected
during construction.”
The project is on a congested urban site in downtown
Washington, D.C. There were strict dewatering standards, which
required water to be quantified and tested for pH and turbidity
prior to discharge. Designs for temporary excavation support were
subject to restrictive load and ground movement criteria and geo-
