SPECIAL ADVERTISING SECTION and Tekla Structures as the managing software packages, merging the various files into a consolidated model. The next step was breaking the project into manageable coordination areas and then controlling the issuance of each subcontractor's respective native files for each area via Turner's FTP server (Turner calls this process ViCon). Turner then streamlined the Navisworks Clash Manager tool to indentify and resolve clashes between building systems and components. Finally, the most critical part of the process was communication -transmitting the coordinated information accurately and timely to the design team for approval, to the shop floor for prefabrication, and to the subcontractors' tradesmen for installation. Final reviews by the design team were accomplished by issuing the final coordinated 3-D model for approval in conjunction with traditional 2-D shop drawings. Similarly, communication with the fabricators and installers was accomplished by a combination of traditional 2-D drawings and the consolidated 3-D model. A sign of the times: during the course of the project, it became very common to see teams of tradespeople huddled around a laptop in the field, viewing and discussing the consolidated 3-D model to better visualize the work under construction. “Utilizing BIM resulted in the majority of HVAC trade hours being in the shop for pre-fabrication, versus field installation, resulting in higher quality, lower cost, and a safer project, for the owner,” said Bob Krier, Hill Mechanical Group's president In the end, the project schedule simply could not have been achieved without significant offsite prefabrication of building systems including piping, ductwork, and large diameter rigid conduit. In turn, the high quantity and quality of offsite prefabrication simply could not have been achieved without utilizing the BIM process as described above. Viewed from this perspective, increased QA/QC and decreased field conflicts and rework seem like mere side benefits of BIM coordination – because this project would not have been possible without BIM. So although this use of BIM – for design, coordination, and fabrication – is just scratching the surface of its capabilities, it is proving to be indispensable for the successful completion of Turner's most complex and challenging projects. “With BIM we are able to provide a higher level of service in a shorter amount of time. In our industry, these types of opportunities don't come along very often, and I am thrilled that we've been able to take advantage of it,” says Dan Harmon, Turner's project executive. The construction industry is one that can be set in its ways and not readily open to change. The use of BIM is certainly a substantial change from the traditional approach to drawing coordination performed by superintendents huddled around a light table looking for conflicts in each other's work. Turner has found BIM to be a tool that expedites and maximizes this coordination resulting in higher quality projects, more dependable and faster schedules and reduced cost of construction, all of which are trademarks of a successful project which increases client satisfaction. As a leader in the industry, Turner is using BIM on all complex projects and assisting subcontractors with making BIM part of their standard operating procedure. A permanent BIM room has been constructed in Turner's office, which will greatly support its use on current and future projects. According to Steve Fort, vice president and general manager, “We quickly realized the benefits of BIM to our projects and in turn our clients and have made BIM part of our everyday business.” Despite the industry's resistance to change, BIM offers such clear benefits that many owners now want it on their projects. Turner, in utilizing BIM and further satisfying its client's needs, is leading the way. BIM 19 http://www.newmill.com/mc http://www.newmill.com/mc
