Minimal construction waste during installation reduces the need
for landfill space and also provides cost savings. Concrete, for
example, has traditionally been pre-mixed with water and
delivered to the site. An excess of material is often ordered, to
prevent pouring delays should a new shipment be needed.
This excess is usually disposed of in a landfill or on-site. In
contrast, concrete mixed on-site, as needed, eliminates waste,
and offers better quality control.
Designing floor intervals to coincide with the standard
lengths of lumber or steel framing members also reduces
waste. Taking advantage of the standard sizes of building
materials in the design phase reduces waste produced by
trimming materials to fit, as well as the labor cost for
