ALDRIDGE INNOVATES:

PreFabrication and BIM Modeling

At Aldridge, collaboration begins early. Our BIM team’s knowledge is critical to helping plan the sequencing of work, identifying prefabrication opportunities and developing a bill of materials to use on bulk material purchases, alongside seamless concept-to-construction workflows.

12’ Pump Station PreFab Build - Rack 7 | Illinois

This 7,100 lb structure, one of the largest PreFab builds to date, was 3D modeled and detailed out to be built directly in the Aldridge PreFab shop.

In Chicago, Aldridge is providing the electrical infrastructure for a pump station project that will eliminate flooding from a nearby river. Before work began, our project team identified an opportunity for utility prefabrication. From there, our BIM team 3D modeled and detailed out Rack 7 (one of two racks), allowing the project team the ability to view the installation from different angles and layers, as well as fabricate the rack right in the Aldridge PreFab shop.

Building this structure using our off-site facility allowed for a more accurate installation. The side entry points needed to align with the in-wall racks and the stub up locations in order to enter equipment openings of the switchgear. The proper alignment was critical to the success of this installation. The result was the fabrication of two large conduit racks designated for utility service and generator feeds which were then tied together and installed in one piece 15 feet below grade in the pump station’s new electric room.

Utilizing our offsite facility minimized on-site safety exposures, reduced in-field work hours, and decreased installation time to drive the project schedule.

70Celebrating Years

Len Aldridge in the late 1960s overlooking blueprints for Fermilab in Kane County, IL. Aldridge was contracted by DUSAF, a joint venture of four firms, to assist in building the original underground power system for the accelerator ring and the overhead transmission line that powered it. This was a major project for Aldridge and helped set the stage for a future rooted in innovation.
