Bergelectric’s Pushes the Boundaries of BIM

At Henderson Hospital—located on the campus of Union Village in Henderson, Nevada and the sixth acute care hospital within The Valley Health System —Bergelectric has utilized their innovative Building Information Modeling (BIM) and Prefabrication resources to accomplish an unprecedented installation process. Challenged with a four-week schedule to perform all below-grade installations in the main electrical room, Bergelectric made use of advanced technology in a coordination effort that could only be defined as “the future of electrical construction.”

Armed with Revit®, NavisWorks®, and AutoDesk Point Layout® (APL), Bergelectric’s BIM Department made it possible to prefabricate the entire underground installation off-site, then ship the assemblies in sections for installation on the job-site. Revit® allowed Berg to digitally embed each conduit with detailed information in the 3D and 2D models (i.e. size, designations, dimensions), color-coordinate conduits to track the appropriate conduit group, define duct-bank cage specifications for prefabrication assemblies, and divide the entire assembly into sections. NavisWorks® enabled Berg’s BIM Department to review the coordination model for conflicts that included footing areas of influence. APL was used to precisely layout the same points off-site that would be used for final placement on the job-site—including walls, grid lines, and equipment windows. “It was an impressive use of modern construction technology,” said Bergelectric’s BIM Technology Manager Derek R. “I am really proud of our BIM Detailers and how they have adapted to using advanced technology.”

“Completion of the electrical underground scope of work was vital for other trades to begin their installation and key for the entire project to remain on schedule,” said Bergelectric Superintendent Mike M. “Pressure was on us to keep the schedule in line, to reduce the stacking of trades on-site, and to reduce safety risks due to the erection of steel on the job-site. We had to turn to our BIM and prefabrication resources for innovative solutions, and they delivered.”

The benefits of prefabricating the entire underground system off-site were stunning. Bergelectric was able to reduce field installation time of the main electrical room from four weeks to just five days—reducing labor cost by 19%. Not only did the prefabrication assembly yard offer Berg crews a controlled/safe construction environment, but the process reduced on-site labor cost, trenching sizes, and on-site safety hazards. Bergelectric was able to expand their existing underground prefabrication capabilities and now have the capacity to include the conduit connectivity of sections within a transportable footprint.

“This project really set new heights for Bergelectric’s BIM and prefabrication capabilities,” said Bergelectric C.E.O. Alan J. Mashburn. “Projects like Universal Health Services’ Henderson Hospital help us to push our boundaries and bring about a sense of excitement for implementing these practices in future projects.”

Bergelectric, in a design-build role with Valley Health System and TJK Engineering, completed the hospital in late 2016.  The UHS Henderson Hospital features: emergency services, inpatient and outpatient surgery, women’s and children’s services including pediatrics and maternity care, cardiology, ancillary services—including radiology, laboratory, respiratory and inpatient pharmacy—and nursing units for medical/surgical care, intermediate medical care and intensive care.
