  1. Construction Management Green Professional Building Skills Training

  2. COURSE OBJECTIVES To understand: A. Environmental impact of construction B.Integrated approach C.Construction practices on a green building Page 1

  3. GPRO Certificate Holders

  4. 1 CONSTRUCTION MANAGEMENT & GREEN BUILDING Page 2

  5. A Green Building A green building is designed, constructed and maintained to minimize adverse environmental impacts and to reduce energy consumption, while contributing to the health and productivity of its occupants.   A key component is consideration of the building's impacts and performance over its entire life. LEED Gold Building, NY What is Green Building? Page 2

  6. LEED Credit Categories: Prerequisites for LEED 1. Sustainable Sitesp1: CAPP 2. Water Efficiencyp1: Water Use Reduction – 20% 3. Energy & Atmospherep1: Fundamental Commissioning p2: Minimum Energy Performance p3: Fundamental Refrigerant Management 4. Materials & Resourcesp1: Storage/Collection of Recyclables 5. Indoor Environmental p1: Min. Indoor Air Quality Performance Quality p2: Environmental Tobacco Smoke Control What is Green Building? Page 2

  7. Whole Building Approach Design, construction, and operation are integrated. What is a Green Building? Pages 2-3

  8. Leadership in Green Design Solar panels A green project has: • New technologies • Improved construction practices • Added verification • Greater coordination • Stronger relationships between CM, Subs & end users Applying Best Practices and Leadership Pages 2-4

  9. CLASS DISCUSSION: What green or sustainable practices are you already doing on your projects?

  10. CM/GC's Roles Relating to Sustainability Page 4

  11. TEST YOURSELF: How does the sustainability concept of integration affect the construction process and the CM/GC's role? Page 4

  12. 2 PRE-CON SERVICES: Sustainability Planning in the Design Phase Page 5

  13. The Sustainability Team Establishing the Sustainability Team Pages 5-6

  14. Case Study: Fort Hamilton Historic Society Maritime Museum, Brooklyn, NY Classroom Exercise #1 Pages 57-58

  15. Case Study: Fort Hamilton Historic Society Maritime Museum, Brooklyn, NY • Owner's Priorities: • Eliminate stormwater runoff • Reduce water consumption • Reuse materials from existing warehouse structure • Use salvaged materials from decommissioned ships • Provide daylit gallery spaces Classroom Exercise #1 Pages 57-58

  16. Defining Sustainability Goals Define priorities & goals in context of project requirements. 16 Defining the Sustainability Goals Pages 6-7

  17. Schematic Design Phase Establishing Goals & Identifying LEED Credits: Assess project potential for LEED certification Identify possible measures & credits Establish proposed sustainability measures Determine feasible LEED credits Confirm goals and credits 17 Schematic Design Phase Page 7

  18. Case Study: Potential LEED Points and Proposed LEED Points Review potential LEED points to determine which are feasible to proceed with. Classroom Exercise #2 Pages 59-62

  19. Evaluating Costs to Prioritize Scope • Simple Payback Analysis: • Payback Period = (Total Cost) / (Annual Savings) • The shorter, the better! • Life-Cycle Cost Assessment: • A more complete analysis, includes: • Maintenance • Future decommissioning • System replacement • Opportunity costs Financial Evaluation of Sustainability Measures Pages 8-10

  20. Simple Payback Analysis ÷ Financial Evaluation of Sustainability Measures Page 8

  21. Payback Analysis Comparison Financial Evaluation of Sustainability Measures Pages 8-9

  22. Value Engineering Green projects have less wiggle room. Substitutions with lower "first costs" may cost a lot more in the long run. Value Engineering Page 11

  23. Incentives Analysis • Primary responsibility by owner or A/E • Funding can come from local, state, federal or utilities • Factor funding into payback analysis process • A/E will rely on CM/GC for data and scheduling info Analyzing Sustainability Incentives Page 11

  24. TEST YOURSELF: What is the CM/GC's role on the Sustainability Team (ST)? How is the CM/GC involved in identifying sustainability goals and target LEED credits? Why and how do you conduct and evaluate a simple payback analysis? What is the CM/GC's role in analyzing sustainability incentives? Page 11

  25. 3 SUSTAINABILITY MANAGEMENT PLAN Page 12

  26. Credit Types TYPE 1: Mostly design team’s responsibility and design team verifies. TYPE 2: Shared design team and construction team responsibility with construction team responsible for verification. The Sustainability Management Plan (SMP) Page 12 26

  27. Create your Sustainability Management Plan • Clarify the following: • Who is responsible for what? • What trades are affected? • What are the documentation requirements and how will they be met? • What work practices are required and how will they be verified? The Sustainability Management Plan (SMP) Pages 12-14

  28. CLASSROOM EXERCISE: Sustainability Management Plan The CM generates the SMP to coordinate the execution of the sustainability measures. Classroom Exercise #3 Page 63

  29. CLASSROOM EXERCISE: Now make the argument to the Owner about how you plan to achieve each credit. Classroom Exercise #3 Page 63

  30. Sometimes Points are Eliminated Delete Solar Thermal System: Financial criteria: Proposed solar system will have a long payback period (increasing water efficiency means less hot water being used) Site logistics: Turns out that the solar thermal system doesn't have adequate southern exposure

  31. Additional Complexities Green building practices can impact schedule, budget, purchasing, and coordination: • Installation sequences • Building reuse • Availability of green-skilled trades • Schedule implications: Flush-out, erosion control, ductwork protection, long-lead-time items • Availability of green materials • Documentation requirements • Logstics and site plan issues • Waste sorting 31 The Sustainability Management Plan (SMP) Pages 12-14

  32. Preparing Qualifications…Present Your Competitive Edge List green strategies from your experience for waste management, IAQ flush out, HVAC retrofits, Cx, etc. Include an organization chart showing team members with LEED AP or GPRO certificate. Responding to an Owner's RFP Pages 14-15

  33. TEST YOURSELF: What elements should you include in your Sustainability Management Plan? When updating your Sustainability Management Plan, what critical elements need to be confirmed? Page 15

  34. 4 TRADE BID & AWARD: Incorporating Sustainability Strategies Page 16

  35. Bid Issues to Explain to Subs • Dispelling the myth of LEED record keeping • Regional, recycled, and FSC certified requirements • Issues that may involve more than one credit • Building flush-out schedule • Cx (commissioning) milestones & inspections Vetting Bids to Ensure Sustainability Scope is Covered Page 18

  36. Things to Look for in Selecting Green Subs • Experience & track record • Certifications or training • Motivation • Openness to use greenproducts • Location of manufacturing or harvesting Creating a Bid List with Green-Qualified Contractors Pages 16-17

  37. Developing Bid Documents to Support Sustainability Goals • Project sustainability goals and LEED credit scorecard • Clarity on shop drawings and submittals & LEED template letters • Sort & salvage requirements • VOC caps • Collaboration expectations • Work practice & documentation requirements Developing Bid Documents to Support Sustainability Goals Page 17

  38. Vetting Bids to Ensure Sustainability Scope is Covered • Participation on Sustainability Team • Time for flush-out & testing • Cx schedule impacts • Local materials acquisition • C&D Waste • Recycled content verification Vetting Bids to Ensure Sustainability Scope is Covered Pages 17-18

  39. CLASS DISCUSSION: What questions would you ask the trades to ensure that they understand the sustainable requirements? Use the SMP as your guide.

  40. Handoff to Mobilization Finally, we're ready to start construction! Do all trades and vendors have the information they need to build a green project? 40 Handoff to Mobilization Page 18

  41. TEST YOURSELF: What should the CM/GC consider when selecting green subcontractors? What are the unique elements of bid documents on a green project? How does the vetting of green bids differ from standard practice? What are the green issues that the CM/GC is responsible for in preparing for mobilization? Page 18

  42. 5 MOBILIZATION Page 19

  43. Core Sustainability Activity Areas Mobilization Page 19
