Stage 3 : Design realisation and operation

During the construction phase some minor amendments may be required to adapt the detailed design to site constraints and accommodate changes in the internal technical specification. If the outline and detailed design phases have been effectively implemented these changes should be minimised. Any major changes to the footprint, height or detail of the building should be avoided. All conditions attached to the planning permission must also be adhered to. Section 106 agreements can also be used to provide planning gain relevant to design. These are legally binding and not subject to appeal.

Long-term management, maintenance and decommissioning should be important considerations in the design process. It is useful to keep a record of feedback on the design quality of the facility to help guide future decision making. Considering the long-term management of the facility during the design stage will help to reduce overall project cost and resultant long-term potential impacts on the environment.
