The project moved forward on the basis of a widespread use of BIM. Models were used for digital information exchange between client, designer, contractor, management organisation and other stakeholders in the project as far as practicable and feasible. BIM was used actively, not only for drawing production but also to improve understanding of the task and achieve transparency. It was used in planning, co-ordination, reporting, communication, interface planning control and quality assurance through all the phases. As detailed design began, the BIM model was exported to IFC format every week and made available to the design team and the client organisation through viewpoint, both as separate IFC files and assembled as a complete Solibri model. IFC file formats were used to share multi-disciplinary models (REVIT for arch, REVIT for M&E, TEKLA for Steel/stairs/canopy and ARCHiCAD for original RIBA stage 3 model for planning submission). Through Solibri all clash resolution reports were issued via. BCF file format, which allowed consultants to import the issues directly into their authoring software, a full 360 degree review process & kept consultants working in their authoring software, but sharing the co-ordinated models as IFC. A full MIDP and TIDP generated and communicated through our CDE to ensure the tight 4 week design delivery program was achieved.
The Mylan Dublin Respiratory Project, Phase 2 consisted of ten separate project areas assigned to seven different contractor companies under the management of the main contractor, M+W Group. Owing to the number of sub-contractors responsible for these separate project areas it was necessary to implement a system to properly and effectively coordinate the site works. The issuing of up-to-date drawing packs, equipment models and the capture and development of as-built documentation also need to be managed. In light of these project requirements and the associated risks, the use of innovative digital construction technologies, including building information modelling, electronic procurement, prefabrication techniques and high definition surveying, were, in effect, mandated for the project. The BIM Execution Plan (BEP) developed by the main contractor recognised the consequences of the delivery of poor quality mechanical and electrical production information.
The Sythwood School project is currently being finalized onsite after being completed offsite at the McAvoy factory floors. The ‘offsite’ advantages of using BIM during the early RIBA stage 4 design co-ordination ensured that key and critical decisions could be made. Without using BIM the offsite build process could not have progressed quickly enough to meet the condensed programme eg. early coordination of roof light/stair/lift within the steel frame, as this needed to be ordered first to suit the build sequence in the factory. BIM model was used to order steelwork; shared model and drawings allowed direct data to be provided to the steelwork fabricator; reducing the lead-time for the steelwork.

The successful delivery of the project to the client’s requirements was predicated on the elimination of delays, disputes and extra costs inherent in a traditional, non-coordinated, site fabricated project. This was achieved through the development of an LOD400 construction model with regular uploads of contractor details in an agreed, interoperable format in conjunction with weekly coordination meetings. All data, produced to recognised international standards, was shared through a designated common data environment and administered with an intelligent project management platform allowing all personnel to work to a defined process using real-time data.With a company goal of ‘Right First Time’Mercury Engineering sought to fully embrace the use of these digital construction technologies to drive the coordination, prefabrication and installation process.
