  3. Benefits of Design Build • DB offers the following: • Poses Least amount of Project Risk to Owners • “Quickest” Project Delivery Method • Early Construction concurrent with Design • “Integrated” DB Team develops design with constructability in mind, which: • Reduces Changes / Change Orders to Project • Reduces need for Value-Engineering / Re-Bidding • Improves quality of Final Design • Can be used on any sized Project • Use of Design Assist Contractors during design

  4. Challenges of Design Build • Minimizes Owner Control over Process • May be Difficult Method to Use on Complex Projects • Building Over-Design may Increase DB Profits • …Did the Owner get the Best Price for the final Product?
