Since 2008 the main focus for “Resource Efficiency” has been the diversion of self-generated construction waste from landfill to uses higher up the Waste Hierarchy. By “self-generated” we mean waste that could have been avoided in the first place by better specification, procurement, transport, storing and handling.
A good example of this approach to “smart construction” is the Meadowlands Stadium project in USA. It used Building Information Modeling (BIM) software tools and Radio Frequency Identification (RFID) tag technology to optimize delivery of 3,200 large pre-cast concrete panels arriving from different parts of the country. This meant that the speed and sequence of deliveries could be altered quickly to reflect real-time changes on the project thereby eliminating waste, optimizing logistics and reducing time.

Resource Efficiency can also be significantly enhanced by Off-site Manufacturing.
A good example is the Barts & The London hospital projects which used Just-in-time delivery from a specially built off-site Construction Consolidation Centre outside the city to deliver 1,000 modules containing nine different mechanical & electrical services and 1,200 external cladding panels. This reduced waste, improve quality and cut deliveries into central London by 75%. Click here for the Barts & The London sustainability case study.
