A Contradiction? (my project is under LEED NC 2009)
The LEED 2009 ref. guide is unclear with the inclusions for Div. 31, and 32. Are base, subbase, subgrade preparations; stone, aggregate and topsoil included in the material costs for Divisions 32 1000 and 32 3000-Asphalt/Concrete Paving and Plantings/Turf? Or do material costs only include asphalt/concrete mixes, associated Joint sealants, asphalt paints, and turf seed, fertilizers? It merely states. "include these Divisions (also 31 6000) in material costs".

The incongruity: our Specification for Asphalt/concrete paving calls "Earth Moving" for subgrade preparation a related requirement under Div. 31 2000 (not an included Div. as stated in Ref. guide) Conversely, the CSI classifications group Bases-base courses within Div. 32 1000 (an included Div. for const. materials)

If helpful, CSI classifications available here:

Can anyone offer insight or direction? Thank you
