Flexibility Ability to react to information and input Open collaboration through design and construction Owner in continuous lead of decision making Design is adapted to Contractor’s approach Decisions are based on real and complete information Cost and risk can be openly discussed Opportunities with CM/GC
CM/GC Process Refinement Organizational Momentum or Inertia Understanding Cost Estimates Contracting Risk Management Challenges from Owner Perspective
Contracting Process Need Decision Makers at Negotiating Table Defining Scope of Early Work Amendments Department of Justice involvement Time between conclusion of negotiations and NTP for work was not anticipated Challenges from CM/GC Perspective
Contracting Process Lump Sum Items require change orders to account for quantity variations or design changes Dividing the work into packages results in multiple bid items for the same scope of work Multiple work packages result in multiple base prices for fuel, asphalt, and steel price escalation clauses Results in extra efforts for contract administration Challenges from CM/GC Perspective
Risk Management What is our definition of Risk? Damage to Third Parties (Liability Insurance) Damage by Third Parties (Theft, vandalism, fire) Equipment Damage or Abuse (Self Inflicted Wounds) Quantity Over-runs or Under-runs Labor and Fringe Benefit Cost Escalations Risk Assessment exercise Challenges from CM/GC Perspective
Risk Management Liability Insurance (Including Pollution Endorsements) Premiums based on total company exposure, not project exposure High Deductible results in Lower Premium Different contractors assess risk in different ways How best to account for cost of deductibles? Who manages Third Party Claims? Challenges from CM/GC Perspective
Risk Management Casualty Insurance (Comprehensive) Covers Vandalism, Theft, Fire, Equipment Damage Premiums based on total company exposure, not individual project exposure High Deductibles reduce premium costs Individual Contractors assess risk differently – Business Decisions ODOT unfamiliar with level of costs shown in estimates Challenges from CM/GC Perspective
Risk Management Equipment Damage or Abuse Typically not covered by insurance Examples include: Tires ruined by debris Forklifts backing into pickup trucks Excavator or Crane tails wing strikes Accidental damage difficult to estimate Challenges from CM/GC Perspective
Risk Management Quantity Over-runs or Under-runs Original intent was that CM/GC bear this risk – all LS items Defining scope time consuming Earthwork and drainage quantities based on original DTM and A&E models CM/GC quantity verification can check A&E model, but not original DTM A&E incurs additional costs refining models Challenges from CM/GC Perspective
WRB – CM/GC Summary • WRB departed from the CM/GC model • There are advantages to CM/GC style contracting • WRB is well down the road to being a successful project • Team members endorse CM/GC contracting • There is work to be done to refine the approach
