  16. Design – Bid – Build Advantages • Widely Understood and Legally Accepted Method • Owner’s Control/input Over Project • Completed Set of Documents When Bid • Competitive Pricing • Single Point of Contact for Warranty Issues Disadvantages • Don’t Know Price Until Bid Day • Additional Design Time • Owner Liable for Design Errors & Omissions • Can Create Adversarial Relationships • No Contractor Input During Design • Low Bidder Not Necessarily Most Qualified

  17. Why Design – Bid – Build? Works Best With: • Relatively Little Staff Experience Required • Cooperative A/E and Contractor Community • Restrictions on other Delivery Methods • Adequate Staff to Handle Multiple Projects • Time Not Restrictive OK if: • Willing to Accept Change Orders

  18. Why Design – Bid – Build? Does Not Work Well If: • You Don’t Want Claims • You Want Most Qualified Contractors • You Need Contractor Input During Design • Cooperative Attitude Does Not Exist • Mandated Minority Involvement

  23. Design – Build Advantages • Single Responsible Entity for Design & Construction • Minimizes Design – Construction Risk • Potentially Less Time / Earlier Knowledge of Cost • Reduction in Disputes • Potential for Construction Methods Integrated into Design – Creative Solutions Through Collaboration

  24. Design – Build Disadvantages • Owner Must Carefully Define Program (Bridging Documents) • Contractor Control May Impact Quality Level • Changes Due to Late Program Alterations • Legal Issues with Use • Selection Process Can Delay Start • Potential Loss of Control During Design Process • Changes Can Happen Without Owner Involvement Which Owner May Not Desire • No Checks/Balances Between Architect/Contractor (Unless Separate A/E Engaged for Bridging and Oversight)

  25. Evaluation Works Best With: • Well-Defined Scope • Specifically Constructed D/B Contract • You Want Little Risk (all responsibility with Design/Builder) • You have No Legal Restrictions on Use

  26. Evaluation Does Not Work Well If: • You Want Input During Design • You want Local/Minority Participation (Sometimes) • There is Not a Shared Understanding • There is Not a Well-Defined Scope

  31. Construction Management at Risk Advantages • Qualifications Based Selection (QBS) • Ability to Fast Track construction • One Point of Responsibility for Project Delivery • Advanced Input on Constructability and Costs • Budgeting Control with CM’s Input • Opportunities for Minority Participation Enhanced Disadvantages • CM Acting as Contractor • Importance of Selecting Right CM – Must be Good at Pre-con and Build • No Contract Between AE and CM • Changes – from Owner’s Contingency or CM Contingency?

  32. Evaluation Does Not Work Well If: • You Don’t Structure your Contracts Well as a “Family” of Contracts • You Don’t Know up Front Difference Between “Cost of Work” and Reimbursables and Fee • You Don’t Understand the Contractor’s Pricing Intimately • AE is Not Familiar with this Approach

  38. PM/CM Agency Advantages • Ability to Use Multiple Delivery Methods • Ability to Fast Track Construction • Competitive Pricing on Smaller Packages • Minority Participation can be Encouraged if Bidding Done Properly • Ability to Budget for the “Total Costs” of Building Program • Facilitator • All Savings to Owner

  39. PM/CM Agency Disadvantages • Conflict from AEs and GCs who Feel the PM is Interfering with Their Relationship with Owner • Upfront Costs may Appear High • Misunderstanding of Roles/Responsibilities

  40. Evaluation Works Best When: • Local Participation is Important • Required Minority Participation • Need for Input During Design from Contractor • Shared Understanding of Project • Need to Extensively Check as Built Conditions • Cost Containment is Important OK if: • Staffing is Adequate to Handle Paperwork/Changes • You Need Design Input • Schedule Needs to be Accelerated

  41. Evaluation Does Not Work Well If: • You Don’t Want to Deal with Change Orders (risk) • Your Architect Does Not Understand Multiple Bid Packaging (May Add Fee) • You Want Guaranteed Cost • You Don’t Understand Ways Fees are Calculated

  42. Conclusion • There is No “Right” or “Wrong” Way – All Methods have their Pros and Cons • Understand the Difference Between “Delivery Methods” and “Management Methods” • Understand the Existing Owner/AE/PM/CM Structure and their Concerns • Risk/Control/Reward must Balance • Relationships Rule the Day
