Section 2: Individual LEED Credit Reviews
LEED Credit MR-2.1:
In response to the CWM specifications, the
General Contractor (GC) or Construction Manager
(CM) initially develops a formal CWM plan, which
is submitted to the owner's representative or
design team for approval prior to construction.
The CWM plan lists the materials to be recycled
and describes the process by which they will be
sorted, hauled, and documented. Typically the GC
or CM will either manage the waste recycling effort
