Turner promoted lean construction principles to the entire Husky Stadium renovation project team from the very start.

Many innovative practices were implemented on the project to streamline construction and increase productivity. The use of Enviro-Beams (composite foam-filled steel beams) saved the project an estimated $160,000 in production and 500 labor hours.

Waiting on a final roofing insulation decision from the Department of Planning and Development, the roofing schedule was becoming much more difficult. The project team brainstormed an idea to convert standard pre-insulated Enviro-components to pre-insulated roof curbs.

When the answer came from the DPD, Turner had already completed the schedule and cost-savings analysis and was ready to order materials. This innovation reduced the schedule by two weeks for the 80,000-square-foot west roof alone.

When the architect saw the potential and size versatility of the lightweight material, the original exterior gutter-system design was changed to concealed gutters using Enviro-Beam roof curbs. As an added benefit, the Enviro-Curbs were easily notched so safety rails could be left in place for the entire roofing installation.

Lean and sustainable, Enviro-Beams are extremely light, made from recycled steel, foam and zero-VOC glue, and they can be cantilevered very easily.

Treated-wood curbs rot after a short period of time, while Enviro-Curbs last almost indefinitely. They are up to 11 inches high where they become an interior curb and are an R-44, compared with an equivalent wood curb that would be an R-3.

The Enviro-Curb design also allows it to be used as a perimeter parapet wall up to 2 feet high. This innovation can be used on almost any type of roof while eliminating bent-plate issues and wood rot, all at a substantial schedule and cost savings.
