Technical considerations involved in the realisation of design projects form the central consideration of this working group. Its concern reaches from the qualities, characteristics and uses of landscape materials through to their detailing and specification. The organisation and management of the landscape construction process are issues, as are the use of off-the-shelf products versus the design of custom-designed elements. Relationships between design, construction, use and maintenance are all important considerations.
