  24. 24. Next Steps • Raising awareness about the strengths and weaknesses of the current situation with respect to Interoperability. • Continue to improve the Interoperability and start to look at the ‘round-trip’ whereby we take information back into the BIM package from the analysis package. • Automation of parts of the process – automatic updating and re-calculation when something changes. • Cloud computing • Key documents • IGT ‘Low Carbon Construction’ report • Cabinet Office ‘Government Construction Strategy’ • ‘BIM Working Party Strategy Paper’© Integrated Environmental Solutions Ltd.
