How to go about it

Design for … 1. Reuse and recovery 2. Off site construction 3. Materials optimisation 4. Waste efficient procurement 5. Deconstruction & flexibility five principles

Insert relevant image design for reuse & recovery

key questions n. Can materials from demolition be reused in the design? n. Can reclaimed products or components be reused? n. Can materials be reused at their highest value? n. Can excavation materials be reused? n. Can cut and fill balance be achieved? How can it be optimised to avoid spoil removal from site? reuse & recovery

design for off site construction

key questions n. Can site? any part of the design be manufactured off n. Can site activities become a process of assembly rather than construction? off site construction

design for materials optimisation

key questions n. Can the design, form and layout be simplified? n. Can the design be coordinated to minimise excess cutting and jointing? n. Is the building designed to standard material dimensions? n. Can the range of materials required be standardised to encourage reuse of off-cuts? n. Is there repetition and coordination of design to reduce number of variables? materials optimisation

design for waste efficient procurement

key questions n. Has research been carried out by the Design Team to identify where onsite waste arises? n. Have specialist contractors been consulted on how to reduce waste in the supply chain? n. Have the project specifications been reviewed to select elements / components / materials and construction processes that reduce waste? waste efficient procurement

design for deconstruction & flexibility

key questions n. Is the design adaptable for a variety of purposes during its life span? n. Does the design incorporate reusable/recyclable components and materials? n. Are the building elements/components/materials easily disassembled? deconstruction & flexibility

The design review process

n. Use existing design team meetings n. RIBA stage C n. Facilitated workshop n. Review design review process

3 sessions n. Awareness n. Creativity n. Reasoning design review process

design review process

next steps n. Decide on options n. Allocate responsibilities n. Review at meetings n. Record in SWMP design review process
