PfS Facilities and Services Output Specification Part B1: Generic Design Brief
Materials efficiency and reducing waste during construction
3.6.1
The project will support national policy goals (e.g. halving waste to landfill by 2012,
adopted in England by the Government’s Strategy for Sustainable Construction), by
reducing waste, recovering more materials and using more recovered material in
new build.
3.6.2
To help achieve sustainable development, materials efficiency should be considered
at every stage of the design and construction process. Guidance to assist designers
and contractors to understand and meet these requirements and to improve
performance in BSF projects is available from WRAP 1.
3.6.3
The use of the Net Waste Method and WRAP’s Net Waste Tool 2 should be
considered as it converts recycled content and waste into a common unit, namely
value.
3.6.4
The Contractor is required to:
a) implement a Site Waste Management Plan that not only meets the
requirements of the Site Waste Management Plans Regulations
2008 but exceeds these requirements by setting project-specific
targets for waste reduction and recovery and measuring
performance,
b) measure and report the quantity of waste produced (tonnes of
waste per £100k of construction spend 3 and per m2 of building
area),
c) measure and report the quantity of waste sent to landfill (tonnes of
waste to landfill per £100k of construction spend and per m 2 of
building area),
d) recover a minimum of 80% of construction and demolition
materials.
3.6.5
The Contractor shall forecast wastage and set targets for waste reduction from the
design stage (for instance by using WRAP’s Net Waste Tool 4), and monitor and
report the forecast and actual performance.
Requirement for higher recycled content
3.6.6
1
The Contractor will ensure that at least 10% of the total value of materials used in
construction and refurbishment derives from recycled and reused content in the
products and materials selected. The Contractor must also demonstrate that the

most significant cost-neutral opportunities to increase the value of materials
deriving from recycled and re-used content (known as ‘Quick Wins’) have been
identified and considered, that good practice has been implemented where
technically and commercially viable, and that the targeted improvements made in
the total recycled content above “baseline practice” for the project have been
quantified.
3.6.7
WRAP’s Net Waste Tool is available on-line to demonstrate forecast recycled
content and actual performance 5.
The Contractor is required to submit a final report summarising performance on waste
materials to the Authority upon completion of the building works, in a format to be agreed
by both parties.
Guidance notes
Clauses 3.6.2, 3.6.3 and 3.6.5 provide a mandate from the client Authority for the
design team to design out waste from the earliest stages of the project. If this is
not done, site waste management planning will typically be left until the preconstruction stage when the design is well advanced and little opportunity remains
for waste reduction and reuse. The Net Waste Tool (which includes tools for use at
the outline design stage as well as optimisation of wastage in the detailed design)
supports design teams in quantifying the top opportunities and focusing efforts on
specific actions.
Clause 3.6.4 a) sets a requirement for a site waste management plan and,
importantly, states that the SWMP must include project-specific targets for waste
recovery and reuse and for the level of recycled content. This clause is supported
by 3.6.4 b), c) and d) and 3.6.6 in which the contractor must measure and report
their level of performance. In England, legally the client Authority is jointly
responsible with the principal contractor for the SWMP.
Clauses 3.6.5 and 3.6.8 enables the procuring Authority to gain confidence in the
contractors’ ability to meet the requirements. The clauses require the contractor to
report on planned actions at the design stage (i.e. before work starts on site) and
again on completion of the works.
The recommended metrics for waste produced and waste sent to landfill follow the
method agreed by the UK Contractors Group.
