The Duke Cameron Science Center parking deck would have been a very challenging project for any concrete contractor. Through rigorous pre-planning, scheduling and a Lean concrete construction approach, Donley’s stepped up to the challenge and succeeded.

The schedule was very tight, with many different trades overlapping each other. Donley’s work started below grade with the foundations in summer 2015 and quickly transitioned into the main structure, going through the winter months into the spring of 2016. Donley’s daily planning and first run study reviews became the key to the safety, scheduling, and success of this project.

The finished product for the Duke Cameron Parking Garage met or exceeded plans and specifications. The underside of the concrete decking was a class A finish, tolerance not to exceed 1/8 of an inch. The top side concrete deck was a rough broom finish with a sloped floor tolerance that had to exceed plus or minus a fraction of inch per foot of sloped floor. The overall finish was accepted and approved by Walker Parking, the engineer of record, and Duke University, the owner, and completed three weeks ahead of schedule.
