Project Team
• Client: University of Massachusetts Building Authority
• User: University of Massachusetts, AmherstArchitecture & Design, LARP, Building Construction & Technology
• Architectural / Structural Design Team: Architect: Leers Weinzapfel AssociatesStructural Design Engineer: Equilibrium ConsultingSER: SGH
• AHJ:MA State Building InspectorMA Board of Appeals
• Construction Team:Construction ManagerTimber Fabricator and Installer
Key Issues
• Danger of “Over Estimating Contingency” by Construction Managers or Cost Estimators due to the “Unknown”
• Importance of multiple Bidders
• Coordination of Fabricator and Installer Team
