  1. 6 PREPARING YOUR TRADES –PROJECT GOALS AND REQUIREMENTS Page 24

  2. Management of Green Job-Sites Everyone on your team needs to be on the same page about the requirements of a green job. 2 Sustainability Training Issues Across Trades Pages 24-25

  3. Inter-Trade Coordination • Examples: • Floor penetrations • Underfloor distribution of HVAC and wiring • Building management systems • Low-VOC materials Sustainability Training Issues Across Trades Pages 25-26

  18. CLASS DISCUSSION: Tradesperson training: Introduce new trades to your green building goals

  19. TEST YOURSELF: Why is it important to train your trades on project goals and requirements? What are the primary green training issues for all trades? Which sustainable strategies can be classified as construction process activities? What green issues must the CM/GC track in each work area as the project proceeds? Page 31

  20. 7 SHOP DRAWINGS & SUBMITTALS Page 32

  21. Submittal Process Overview Integrated with standard best practices. Review subs' submittals before they go to A/E for compliance with sustainability goals. Submittal Process Overview Page 32

  22. Material Submissions – Substitute Carefully! Anyone making purchases or overseeing receipt of materials must ensure that the materials match the specifications. • Wood certified by the Forest Stewardship Council (FSC) • VOC limits • Recycled content 22 Submittal Process Overview Pages 32-33

  23. Special Issues for the CM/GC to Require, Track, and Document Dual-flush toilet Special Issues for the CM/GC to Require, Track, and Document Page 33 Sustainable Sites: • Erosion & Sedimentation Control Plan (ESC) Water Efficiency: • WaterSense and ENERGY STAR labeling Energy & Atmosphere: • Verification of ENERGY STAR labeling • Cx documentation 23

  24. Special Issues for the CM/GC to Require, Track, and Document Special Issues for the CM/GC to Require, Track, and Document Page 33 Materials & Resources • Verify geographic area where material was extracted, processed, or manufactured • Verify quantity of pre- and post-consumer recycled content • FSC verificationchain of custody • Verification of rapidly renewable content • C&D dump tickets & hauler certifications 24

  25. Special Issues for the CM/GC to Require, Track, and Document Special Issues for the CM/GC to Require, Track, and Document Page 33 Indoor Environmental Quality: • Green labeling and low-VOC product letters • IAQ inspection checklist 25

  26. Sample Materials Certification Form • Materials certification letters • Reporting templates

  27. CLASSROOM EXERCISE: Four students will receive a LEED credit reporting form and are responsible for gathering verification data and filling the reporting form out. All other students use cut sheets to deliver verification data to appropriate “Construction Manager.”

  28. TEST YOURSELF: Is the shop drawing submittal process different on a green job? If so, how? What types of additional documentation are required from the CM/GC and your subcontractors? What products require additional documentation to verify sustainable specification conformance? Page 33

  29. 8 ROUGH-IN, FINISHES & FIT-OUT Page 34

  30. Primary Job Management Areas: Rough-In HVAC/Controls Plumbing/Pipefitting Electrical Indoor Air Quality Plan Construction Waste Management … and don't forget commissioning! Primary Job Management Areas: Rough-In Pages 34-35

  31. CLASS DISCUSSION: What project management practices and tools can be used to ensure that you are properly tracking and addressing issues at this stage?

  32. Primary Job Management Areas:Finish & Fit-Out Work Indoor Air Quality Sequence installation Proper on-site storage of materials Ductwork protection per SMACNA guidelines Confirm all openings in piping or ductwork sealed until start-up Low VOC-emitting finishes Ductwork protection Primary Job Management Areas: Finish & Fit-Out Work Pages 35-36

  33. Primary Job Management Areas:Finish & Fit-Out Work MEP & Life Safety Systems Confirm HVAC controls meet specs & set points Ensure specifications on lighting, sensors, & renewable systems Verify pipes and ducts are properly insulated Confirm plumbing fixtures meet low-use specifications Primary Job Management Areas: Finish & Fit-Out Work Page 36 33

  34. TEST YOURSELF: What green elements require CM/GC tracking and verification at rough-in? How do you use your Quality Control Plan to ensure that you are catching all the issues? What are the primary green issues the CM/GC must watch out for at the finishes and fit-out stage? Page 36

  35. 9 COMMISSIONING & CLOSE-OUT Page 37

  36. The Commissioning Process • Commissioning (Cx): • Verifies that a facility has been designed, constructed and tested to perform as expected. • Relies on coordination and cooperation with all contractors for a successful project. Commissioning Page 37

  37. Commissioning Agent (CxA)'s Responsibilities • Primary tasks: • Design Review • Construction Inspections • Performance Testing • O&M Training & Turnover Commissioning Page 38

  38. How the CM/GC is Involved in Cx Activities • Design Review • Assist in value engineering • Support development of the Cx Plan • Provide submittals and shop drawings for review • Construction Inspections • Arrange for installation inspections • Coordinate pre-functional and start-up tests • O&M Training and Turnover • Develop O&M manuals and training • Troubleshoot systems Commissioning Page 38

  39. Fundamental vs. Enhanced Cx Commissioning Page 38

  40. The Commissioning Plan • The Commissioning Plan is generated during the design phase. • Cx Plan Details: • Overall testing plan and schedule of tests • Forms to record outcome • Required test devices • Personnel responsibilities Commissioning Pages 38-39

  41. Coordination with the Trades Best known benefit of Cx: Smoother, quicker turnover of building systems to operations staff. A clear description of the expectations and responsibilities of each team member will help the Cx process. Commissioning Pages 39-40

  42. Primary Systems to be Commissioned Energy-related systems including: HVAC&R: Mechanical and passive systems and associated controls Plumbing: Pumps, boilers, domestic hot water, recycling systems Electrical: Lighting and daylighting controls,renewable energy systems Commissioning Page 40

  43. Possible Other Systems to be Commissioned • Building envelope • Water treatment system • Stormwatermanagement system • IT infrastructure Commissioning Page 40

  44. What Occurs During Testing? • During testing: • Check for damage, deterioration, and component failures • Functional tests of individual components • Operational tests and measurements of the energized system • (Deferred testing may not occur until after occupancy) Commissioning Page 40

  45. Troubleshooting During Testing • If problems occur: • Troubleshooting techniques • Consult equipment and component manuals • Check wiring • Re-verify wiring terminations Safety checks should be performed at all times. Commissioning Page 40

  46. Documentation for Commissioning • Keep track of all documentation including failed tests and remedial actions. • Deficiency reports leads to remedial action • Resolution record will show that the system functions correctly • Use these records to help support future troubleshooting • (Don't forget to take photos) Commissioning Pages 40-41

  47. O&M Training Equipment is fully operational for the first time during Cx – use the opportunity to train O&M staff to prevent callbacks. Commissioning Page 41

  48. Electrical Work and Commissioning • The electrical distribution system is the foundation for all other systems in the building. • Electricians play a critical role in building performance by preventing electrical failures. Commissioning Page 41

  49. What Electrical Systems are Commissioned? • Lighting and lighting controls • Emergency power • HVAC equipment • Uninterruptible power Commissioning Page 41
