The Stuckeman Family Building For The School of Architecture and Landscape Architecture Stephen R. Chesko Construction Management Waste Management Schedule Field Workers ~ Average of 2 to 5 minutes per day ~ Approximately 9 to 22 days per year ~ Two to Four Weeks to the project Schedule ~ Could result in $26,000 in added labor costs Superintendents ~ Average of 15 to 20 minutes per day ~ Approximately 65 to 87 hours per year ~ Could result in $1,740 in added G.C. costs

The Stuckeman Family Building For The School of Architecture and Landscape Architecture Stephen R. Chesko Construction Management Solution Pre-Construction Investigation Detailed Waste Management Plan Extensive Worker Training Early involvement of Waste Management company

The Stuckeman Family Building For The School of Architecture and Landscape Architecture Stephen R. Chesko Construction Management Conclusion Could delay project up to 2 weeks. On an average project size of 100,000 sf, the differences in recycling costs for the designated areas could be as much as $20,250. Added to the lost labor costs calculated above brings the grand total for an average project to $47,990. Differences between recycling cultures can be prevented by taking the proper steps.

Construction Building Background Analysis I – Structural Truss Re-design Analysis II – L.E.E.D. Waste Management Analysis III – Raised Access Flooring Sequencing Conclusions

The Stuckeman Family Building For The School of Architecture and Landscape Architecture Stephen R. Chesko Construction Management Conclusions Accepting the Value Engineering Re-Design of the Structural Truss would have reduced the schedule by two weeks and saved approximately $148,382. Although the differences in recycling cultures can affect a project drastically, proper pre-planning of the Waste Management Program can minimize the disparity. The use of 3D and 4D models for the coordination of under-RAF systems is effective in determining conflicts; however, is not considered practical in the construction coordination venue.
