2.2. Design and management services to projects represent another1% <strong>of</strong> GDP (ref 3) and are classified as Business Services. Half <strong>of</strong> theannual construction capital spend is also classed as Repair, Maintenanceand Improvement, the realms <strong>of</strong> Asset and Facility Management.Trade in, operation <strong>of</strong> and management <strong>of</strong> buildings and property (RealEstate Services) is another huge part <strong>of</strong> the economy: 7.1%. All theseoperations will be transformed by <strong>BIM</strong>-related practices. In total therefore,<strong>BIM</strong> will impact directly on nearly 15% <strong>of</strong> GDP.2.4. The major opportunity for UK-based construction businessesin the current decade is to win work in the expanding markets <strong>of</strong> thedeveloping world. Currently about £7.6Bn is earned by export, around1% <strong>of</strong> contracting work, 4% <strong>of</strong> consultancy and 10% <strong>of</strong> materials andproducts business. Global Construction 2020 (ref 4) in 2011 set outthe expectations <strong>of</strong> a team <strong>of</strong> economists for the pattern <strong>of</strong> demand inthe current decade. This forecast might now be considered somewhatoptimistic about recovery from the recession, but its pattern <strong>of</strong> relativepositions is still relevant. Demand flows from a combination <strong>of</strong> populationgrowth and its urbanisation rate, economic growth and propensity2.3. Indirectly, <strong>BIM</strong> will influence performance in the sectors whichto invest in construction as a proportion <strong>of</strong> GDP.occupy and use buildings and infrastructure. Built environment is anenabling sector, facilitating the performance <strong>of</strong> most other sectors.2.5. Global Construction 2020 says that the annual amount <strong>of</strong>construction to be done globally will rise to $12tn in 2020, up 67%from 2010 and forming 13.2% <strong>of</strong> world GDP. $97tn will be spent inthe decade. The growth will come entirly from the developing world;Built environment is also the dominant consumer <strong>of</strong> utilities, electricity,gas and water, the source <strong>of</strong> most waste, plus the locus <strong>of</strong> almost allfixed ICT. <strong>BIM</strong> will affect performance in these sectors. Infrastructure isa substantial part <strong>of</strong> the built environment and is mapped on geographicinformation systems (GIS). GIS and <strong>BIM</strong> developed separately butare conceptually related and should become seamlessly linked to enablebetter development and regulatory control. The Internet <strong>of</strong> Things(IoT, where sensors on objects communicate via the Internet Protocol)is emerging as a further factor. This affects how building elements aretagged, shipped and tracked, but also how they can form a sentientsystem to support the construction and operation <strong>of</strong> the building, infrastructureelement or district. <strong>BIM</strong> will link into IoT, providing ‘Big Data’and tools to manage the so-called Smart City environment and theSmart Grid for power management.Wuxi Shopping Centre, atrium, for Inter Ikea Centre GroupG r o w t h t h r o u g h B I M15
