LEED Credits and Contractor Responsibility
Defining the role of the Contractor
Implementing LEED requirements on the construction site
Challenges, obstacles, issues for contractors
Cost of implementation
To define “green” and “sustainable” buildings by providing a rating system by which the design for energy and environmental criteria can be measured.
Establish a benchmark which buildings can be measured against
LEED®Leadership in Environmental and Energy Design
Energy and Atmosphere

Pre-Requisite 1 Construction Activity Pollution Prevention
BULLETIN 2002-003-EV Effective May 1, 2002, an Erosion and Sediment Control Plan is required for all construction activities where the soil is disturbed and sediment or construction related wastes may be discharged into the City Sewer system. The Erosion and Sediment Control Plan must be submitted as a part of the building permit application.

DOCUMENTATION COLLECTION AND SITE VERIFICATION
Develop a Green Building Risk Profile
Define which party is responsible for administrating the LEED certification process. Define your responsibilities and level of participation in achieving the points.
Define responsibility if the project fails to achieve LEED certification and what sort of damages flow from such a failure.
Review the language of all the contract documents
Keep in mind it is a 3rd party verifier that has not been involved in the project at all.
Confirm that there is adequate insurance coverage, including professional liability insurance for design professionals, that takes into account the green nature of the project
St. Charles Building and Code Enforcement Commissioner Bob Vann said the building is so uniquely designed only the original structural engineers have the knowledge to pinpoint exactly what went wrong. Until then, no one will be allowed in the building except to possibly remove some computers and other necessary work materials..
Address the length of time of inspection and documentation processes associated with LEED certification in the project construction schedule.
Inspections 3-4 weeks in conjunction with Occupancy
Documentation and Submission 4-6 weeks after project completion
Audit and Certification 18 – 24 months for certification
Commissioning (M&V credit) requirements may result in an additional holdback period of up to 1 year after substantial completion of the work
If certification of the project is made contractual, final holdback may be extended by up to 2 years
“As a condition of Substantial Performance the Corporation will holdback from the applicable progress payment $100,000 dollars from the Contractor until LEED Certification has been achieved”
Contractors turning away from LEED
The construction industry in B.C. and the U.S. is starting to reject the LEED certification process citing it as too costly and taking too long with too many uncertainties.
“You can wait up to two years to get certified, the backlog is extraordinary,” said Helen Goodland, principal of Brantwood Consulting, a green building consultant.
The firm is heading a stakeholders group seeking to find alternatives to achieving energy efficient buildings and reducing B.C.’s greenhouse gas emissions by 33 per cent by 2020.
“The industry is quite reasonably rejecting LEED,” she said.
Goodland cited figures for Vancouver, where only 13 per cent of the structures built to a LEED standard are currently certified.
If all the LEED buildings in the US registered today (35,000) were net zero it would only equate to 1% reduction in total energy use of all the existing buildings in the US
LEED buildings themselves are not going to impact the industry as much as code will
We need to be raising the bar with LEED as well as bringing it up from behind with building code
