Commonwealth’s Omaha, NE, location has recently begun work on the Tenant Improvements (TI) portion of a local skyscraper. Starting with Level 19, a raised computer floor has provided the opportunity to run Metal-Clad (MC) Cable underneath. This allows easier access to wiring later on, as individual grid sections can be removed to extend wires to in-wall devices.

All boxes, conduit runs, and MC Cables are laid out by the on-site crew, with layouts labeled by footage and circuit numbers. Our prefabrication team then transforms these layouts into the assemblies shown in the pictures. Preconstruction Services Coordinator Sarah DeWispelare takes the 2D drawings, converts the MC footages, and creates to-and-from labels for each circuit between boxes.

Prefabrication Managers Troy Savich and Jeff McCuen, along with the team at our prefab shop, build and package the junction boxes with whips included, wires terminated on the terminal blocks, and circuits labeled. Journeyman Electrician Zach Halbert has been leading the organization and packaging of these assemblies.

Once complete, the kits—containing any prefabbed conduit, straight conduit, fittings, and boxes associated with each spider box—are stored in our warehouse. When the crew is ready on-site, General Foremen Bryan Furmanski or Bob Bohling submit a warehouse request form to schedule delivery of the floor kits. Warehouse Manager Paul Brousek then coordinates delivery to the jobsite, where the driver takes a photo upon arrival to notify the general foreman.

On site, Foreman Ethan Smith distributes each kit to the correct zone and begins stringing out the MC cables and running conduit. This process is a strong example of how cross-departmental collaboration can streamline field installation.
