What is CMGC? A Project Team consisting of three components: • An Owner • A Contract with a Designer • A Two Phase Contract with a General contractor • Phase one – A “Construction Management” consulting contract to help with design • Phase two – A “General Contracting “ contract to build the project 3
Overview CMGC Contract Structure A Project Team consisting of three components 1 1 • Owner • A Contract with a Designer • A Two Phase Contract with a General contractor • Phase one – A “Construction Management” consulting contract to help with design • Phase two – A “General Contracting “ contract to build the project Owner 2 3 2 CMGC 3 Phase 1: Construction Management Designer Design Phase One RFP Phase 2: General Contracting Construction Phase 4

CMGC Highlights • Key Finding FHWA Utah Peer Exchange 2011: • CMGC/CMAR project delivery “is a less radical shift in procurement culture than design-build…” • Owner retains control of the design • Designer is true owner’s representative 49
Who is Using CMGC/CMAR? • Research done in 2009 (NCHRP Synthesis 402) • Five states were using CMGC/CMAR – AK, OR, UT, FL, AZ • Six additional States have legislative authority • Quick look at current conditions (2011) • Now Using/ working on CMGC/CMAR: MI, CO, CFL, MTO, ME, WFL and NV • EDC follow ups to EFL + 9 others 58 11

CMGC is not CM@Risk • The process is not the vertical world of CM@Risk– similar but different • Transportation industry projects are different and require a process of their own • Self-performance requirements are typical • Subcontractor procurement process is different • CMGC relies on best-value selection • GMP timing 13
CMGC is not CMAR With CMAR: • Negotiated prices vs. “BID” • Very little owner involvement during construction • Contractor selection is QBS vs. Best Value • Focus is on Quality vs. Risk and Price 46 14
BIG Picture Theories with CMGC • Collaboration • Risk Theory • Schedule • Model to Implement Innovation 15
CMGC Contracting CMGC is an integrated team approach to the planning, design and construction of highway projects.
Contracting Types ComparedRisk Theory Lower Risks Design-Bid-Build CMGC Design-Build Total Amount of Risk Owner Shared Contractor Primary bearer of Risk: Higher Lower Higher Relative Level of Risk Disconnect between design and construction leads to suboptimal design decisions and construction delays. Collaborative design process leads to readily constructible plans, faster construction times, and innovative approaches. Owner relinquishes control of design and construction to gain speed of delivery Drivers of Risk:

OverviewKey Benefits of CMGC • Constructability • Collaborative Design Process • Competitive pricing • Reduced Risk • Relationship Building • Speed of Delivery 20
What does an owner expect? Can all of these be improved? • Better Designs • Better, Faster schedules • Lower risk • Lower costs • Savings in design • Savings in constructability • Savings in innovation Scope Schedule Budget 21

New Business Model • New paradigm • Lowest construction cost • to lowest project cost • Societal costs minimized • Public praise • Political capital
What Does industry get from CMGC? • Better Designs – Hard to Quantify – Contractor satisfaction with plans, CO’s • Better schedules- Exceeded expectations • Lower costs • Savings in design- preliminary savings indicated 40% of design costs • Savings in constructability- preliminary savings indicated 8% of total project combination with innovation • Savings in innovation- preliminary savings indicated 8% combination with constructability
CMGC in ActionThe Bottom Line Lower Costs CMGC has delivered 15-16% cost savings and lower change orders for Utah Cost experience for UDOT, based on 18 state projects $330 million dollar program
CMGC Contracting Bottom Line: CMGC is a good option for many transportation projects where the qualifications and cooperation of the contractor are critical to the success of the project.
