Powering Up The Largest Land Port On Earth

Berg’s use of Building Information Modeling (BIM) for all underground and building structures was essential for planning and successfully traversing Interstate 5 (I-5) with a duct bank designed to link the standby generator to the electrical systems in the new 87,000-sf operations building. Berg relied heavily on their BIM Department throughout the course of construction which was key in maintaining a smooth installation process. BIM also provided Ber’s General Foreman, the necessary tools to expertly manage an intricately-choreographed nighttime process of crossing the I-5 within a two-week window.

The underground systems portion of this project was massive. After underground layout designs were fine-tuned and detailed by Berg’s BIM Department, specs were given to their Prefabrication Division for mass production of underground conduit in metal frames dubbed “Duct Bank Cages.” These Duct Bank Cages are produced off-site, in a controlled location, by Berg’s own experienced electricians. And since space was limited on the jobsite, Berg’s ability to produce large quantities of Duct Bank Cages along with other assemblies—like strut supports, conduit bends, and electrical receptacle frames (called kick-in boxes)—was essential.

Tapping further into technology, Berg effectively utilized Trimble® Total Station to locate hundreds of stub-ups for approximately 25,000 feet of conduit located at the Northbound Secondary Vehicle Inspection facility. BIM played a key role in installation of a 12,000-volt feed for the project—helping crews navigate through congested utilities, streets and sidewalks to ensure the new feed was within code and avoided clashes with other utilities.
