02 Delivering effective Waste Minimisation
Guidance Note 2: Design
Design presents some the greatest
opportunities to influence waste. The principle
of waste minimisation in design includes
‘designing out waste,’ the use of efficient
design and planning to reduce the quantity of
waste before it arises onsite and the use
of MMC. Failure to think about waste during
design means that the contractor is often
unable to reduce some of the wasteful
elements which have been ‘locked in’ by
the designer. Therefore, getting the design
right – i.e. ensuring that wasteful elements
are addressed – means that the contractor’s
role is much simpler.
Checklists are provided to aid the Client team,
Design team and Constructor team to address
construction waste in design.
Guidance Note 3: Procurement
The principle of waste minimisation in
procurement involves producing accurate
estimates of materials required and then using
these materials more efficiently. The quantity
of materials ordered is often inaccurate and
unreliable and results in over ordering and
material wastage. This is an area where costs
can be saved through buying better. There is
scope for waste (and its associated cost) to be
accurately estimated, controlled and reduced
during procurement.
A series of checklists and proformas are
provided. These are aimed at subcontractors
for improving the material ordering process in
terms of robust allowances for waste and data
gathering on how much waste is generated so
to improve the waste profile. Potential actions
by subcontractors are provided in four stages:
planning;
implementation;
review; and
improvement.
Guidance Note 4: Logistics
Efficient logistics can play a large part in
reducing waste derived in transit to or on
site. The development of a robust logistics
plan is fundamental to effectively reduce
waste. A logistics plan identifies how materials
are moved to, from and on site and how they
are stored. Efficient logistics is based on the
rigorous assessment of the need for materials,
coordinating delivery, storage and distribution.
WRAP are currently developing a logistics plan
template guidance document.
