DCG Receives ABC Eagle Award for Duke Cameron Parking Deck

Donley’s
Concrete Group is excited to be receiving the Carolinas Chapter ABC Eagle Award
(Excellence in Construction) for Duke Cameron Parking Deck.  The project
won in the category for concrete projects over $10M. The Excellence in
Construction Awards celebration honors Carolinas members’ most innovative and
high quality construction projects, and safety programs. 


The Duke Cameron parking
garage, designed by Walker Parking, the engineer of record, created a very
challenging 2,000 car structural concrete parking structure. The 775,000 sq.
ft. structure was completed in 12 months. The aggressive schedule proved
challenging with the design requiring very strenuous specification
requirements, calling for very specific quality control measures start to
finish to produce the desired finished product for Duke University. A separate
QA/QC person was hired to be at the site full time to test every truck for the
deck pours at the end of the pump, correct and timely installation of
reinforcement and post tensioned cables and double check the reinforcing
subcontractor’s daily installations.

The
12 month schedule was challenging, but Donley’s Concrete Group’s daily planning
and first run study reviews became the key to the safety, scheduling and
success of this project. Through use of maturity meter testing for in place
concrete strength and visual planning tools for daily tasks, the team was able
to use their valuable time in the most productive way possible.

Another
obvious challenge of the project was working on this massive structure within a
fully operating campus. The overall logistics of the site, schedules,
deliveries and safety became paramount with students and faculty constantly
moving around the construction site in close proximity. The solution to working
on a fully operating campus was to implement night concrete pours. A large
majority of the concrete that was placed on the parking decks was placed at
night, with concrete pours between 500 to 600 cubic yards per placement and
taking 8 hours to place.


With the many challenges
faced in the beginning, Donley’s utilized scheduling tools to manage the team
and complete construction. Which in the end, helped Donley’s team finished the
job three weeks ahead of schedule.
