Traditional Project Delivery Approach
Steps of Traditional Project Delivery Approach
• Owner contacts architect
• Architect designs the project and develops construction documents over time
• Project is let out for competitive bid
• Contractor is selected and construction begins

Proposed Alternative Project Delivery Approach
Basis of Alternative Approach
• Communication is key to successful project delivery
• Poor communication leads to cost overruns, delayed schedules, and numerous changes
Goal of Proposed Alternative
• Improve overall communication
• Reduce cost overruns, delayed project delivery, and design changes

Role of Construction Manager in the Design Process
Analysis IResearch: Means & Methods
Research Means:
• Alternative approach very feasible and appealing to construction managers
• Owners do not recognize benefit and value of a construction manager during the design process
• Research survey and interview questions developed and distributed to industry members
• Research Goal – To determine the value of a construction manager in design
Research Methods:
• 18 question online survey distributed to approximately 52 industry members: (19 architects, 7 owners, 22 construction managers, 4 general contractors)
• Interview questions distributed to 8 individuals (Two of each discipline)
Research Results:
• 25 responses to online survey: (7 architects, 2 owners, 12 CMs, 4 GCs)

ConclusionSummary and Conclusions
Reducing the Impact of Phasing
• Utilize the knowledge and expertise of a construction manager early in the design process
• Investigate temporary structures to limit the alteration of the final design and to reduce the complexity of the future construction
• Early CM involvement could also allow for early involvement of key subcontractors and allow for the use of 4-D modeling
Impact of Phased Construction
• Requires a great deal of planning and communication between design and construction
• Potential for extensive over-design of project components to accommodate temporary loads
