Michael Funk

Project Overview

Conclusions

Problem• ‘Going green’ trend continues to increase• LEED points can be hard to obtain• Focus gets lost on the project

Existing Research• Setting early “green” goals is critical

Goal• Identify LEED® points that are attainable based on project

type• Develop a guide that can be distributed to project team to

aid in obtaining these points

Michael Funk

Project Overview

Conclusions

Research Steps:• Literature review to become more familiar with LEED®• Identify and interview different owners on different LEED® Rated

projects• Surveyed owners and project managers• Develop an outline for a guide that will benefit owners and project

managers from the start of a project• Developed a spreadsheet format for each LEED ® point • Had several project managers test out the guide, obtained

feedback, and developed a final version

Project Overview

Conclusions

New layout provides a more balanced schedule

Phase 3 is lighter to allow for make-up time if any previousPhases get behind

Places the work in a nice flow based on what work is being done and the school remaining open

Project Overview

Conclusions

Bulk Excavation (current) versus Trench Excavation

Goal:Reduce labor costs, schedule, and the amount of material used

Trench excavation eliminates the need for forming and reduces the amount of material removed and the amount of fill

Conclusions

Outcome• Increased safety measures must be taken• Trench Method Saves

– $46,211• Reduced spoils

• Removal of formwork labor

and materials

– 2 days off schedule– 826 BCY reduction in spoils

• Reduced by roughly 77%• Reduced site disturbance
