Turner Construction Design-Build BIM Case Study

During the 2012 Federal Sector Design-Build Conference, Turner Construction and the US Army Health Facilities Planning Agency (HFPA), provided an informative & entertaining Advanced BIM | Design-Build educational program titled:

Utilizing BIM to Leverage Knowledge & Coordination Across the Project Delivery Team

Martin Miller, LEED AP of Turner Construction kicked off the session alerting attendees “We’re here to serve up the BIM Kool-Aid” — and then promptly pulled out the classic “smiling Kool-Aid pitcher” filled with red Kool-Aid.

Turner Construction’s staff featured their successful BIM – connected design and construction processes they’re using to construct the The Fort Benning Hospital.

Jeff Bauer VDC Engineer \ BIM Manager for Turner Construction highlighted the team-value, obtained from the following Revit, BIM processes & technical processes:

There was extensive use of BIM animations and rendered images to communicate across the team for proposal creation and responding to the RFP process.
BIM X-Ray Images: BIM models viewed with shaded, but semi-transparent surfaces for team coordination review.
BIM modeling & embedded data was used for Field Management, Construction Site Safety Planning & Construction Logistics-Phasing Planning
Managing Room Content Lists & Schedules with Revit to assist with project programming & scope.
Storage & Bandwidth was always monitored to efficiently manage 200 models (5GB). Managing data & file sizes required a fast onsite network, consistent BIM model-graphics standards & methods for revision control.

Turner used their (JOBOX) mobile BIM Labs; that were located in three main campus buildings (Hospital, North Clinic, and South Clinic)

Turner Mobile BIM Lab JOBBOX for Virtual BIM Construction Processes

Turner Construction created an Onsite BIM Lab to manage the daily Design, BIM & Construction Processes. Here are a few outcomes and processes utilized within the lab:

Navisworks was used regularly every day to plan, evaluate models and simulate construction decisions & processes.
Everything in scope was modeled prior to construction.
Shop drawings coordination using an IFC file format
Commissioning documentation is created as construction progresses to expedite submittal.
Prefabrication process was used extensively; including the use of bar coding of prefab assemblies; that defined their installation locations. QR codes for material tracking from manufactures to site, provided delivery for installation to the correct location on the campus.
A completely committed team working within a BIM process; underscored the schedule + budget value of EVERYONE using and participating in the BIM process.
The BIM process’ significant contributions to project schedule & budget; keeping a very aggressive program on schedule and within budget.

The BIM process has enabled the sub contractors to leverage the geographically-positioned (GPS) BIM-enabled modeling. Our teams collect point locations from the coordinated BIM model (In the Office) for layout in the field.

An excellent example of this time saving, safer, and efficient capacity is installing 100,000+ hanger inserts in metal deck before concrete is placed.

This traditionally is done from the underside after the concrete is placed, using a ladder (Less safe), drilling up into the underside of concrete. One worker could install approximately 20 holes a day.

The GPS \ BIM-enabled process, empowers a crew of 3 workers to install (From top of metal deck and walking with no ladder needed– Safer) to install 750 hanger inserts\day.

Installation is much faster and safer – Simply walk to the location and screw in the threaded rods for pipe hanger racks, cable tray, electrical conduit racks, etc.
