9 PROJECT APPROACHES Common project delivery methods: Design Bid Build Design Build Delivery method for energy projects: Energy Savings Performance Contracting Integrity Excellence Respect 9

10 Most common; construction awarded to lowest bidder Owner contracts directly with A/E Firm and Contractor Slow process (bid design, develop bid package, bid construction, construct work) Firm scope of work defined upfront Change orders / owner risk Known fixed budget TYPES OF CONTRACTS DESIGN BID BUILD Heavy administrative support required during construction (RFIs) Integrity Excellence Respect 10

11 TYPES OF CONTRACTS DESIGN BUILD Owner hires single Contractor for design and construction based on best value Scope of work defined, but changes may be made during development Known fixed budget Change orders less likely More administrative support needed prior to construction Integrity Excellence Respect 11

12 ENERGY SAVINGS PERFORMANCE CONTRACTING State hires a single, pre-qualified Contractor: Energy Services Company (ESCO) Multiple funding sources used; no budget cap All parties cooperatively develop performance based scope of work Accelerated delivery; typical development 4-6 months prior to construction Integrity Excellence Respect 12

13 ENERGY SAVINGS PERFORMANCE CONTRACTING Open book Guaranteed Maximum Price and energy & operational savings determined upfront High degree of end user control of equipment and installation methodology used during construction Optional savings performance guarantee Budget neutral, savings repay financing No change orders Integrity Excellence Respect 13
