3. Potential OptionsRefinementImplementation Operations & Maintenance Step 4: Implementation 3 Purpose: Contract for, realize physical construction of project Tasks: Finalize project agreements Finalize vendor contracting process Finalize preconstruction tasks Realize construction and equipment installation Realize interconnection Realize project commissioning leading to commercial operations Output: Completed project (operation)

4. Step 4: Implementation 1.Financial closing (if applicable) 2.Contract execution 3.Construction of project  Contract oversight/quality control  Change control 4.Commissioning  Testing and verification  Interconnection verification (utility) 4 Variable effort relative to project scale

5. 1. Financial Closing (if applicable) The process of completing all project-related financial transactions, finalizing and closing the project financial accounts, disposing of project assets, and releasing the work site. 5 A few key steps: Establish and communicate final date for all financial transactions and account closings well before closing Verify all items from the Statement of Work have been completed before disbursing final payments Collect all financial records and verify all financial obligations have been satisfied Close all financial accounts Transfer or dispose of assets according to the acquisition plan

6. 2. Contract Execution Verify contract documentation Obtain contract approvals Book the contract Transfer project responsibility to project manager 6

7. 3. Construction of Project Project developer orders equipment and begins construction or installation Construction manager coordinates work of various trades Close coordination with tenants if building is occupied Frequent communication between all parties to minimize possible issues 7

8. 4. Commissioning 8 Planning Determine objectives and strategies Assemble project team Compile and review building and equipment documentation Investigation Conduct site assessment Develop functional test and monitoring plans Analyze test results Compile master list of deficiencies and recommend improvements Implementation Accepted recommendations are put in place Repairs and improvements Retesting and re-monitoring Fine-tuning Hand-off and Integration Final documentation of commissioning effort is presented Develop and present plan for future commissioning efforts including recommended procedures for specific equipment, frequency of testing, analysis of results, periodic reporting, key players, and budget requirements
