Project Details

Witech turned a former 85-acre cornfield into a 1.5-million SF IKEA distribution center with 115 ft ceilings in Joliet, IL. for Gray Construction, with the help of engineering firm Jacob Heffner & Associates.

Using Quadtrac scrapers with pull pans, along with excavators and articulating haul trucks, crews completed more than 500,000 CY of earthwork, excavating and backfilling more than 1.2 million SF on an aggressive schedule.

In preparation for the concrete slab and pavement, Witech had to chemically modify more than 900,000 SY of soil and place more than 125,000 tons of aggregate for the building slab on grade and exterior pavement.

Gray Construction is working with Witech Excavating Company on the IKEA Distribution facility in Joliet, IL. We would like to extend our sincere recommendation for Witech on any construction projects and also express our desire to work with them in the future.

Witech has performed above and beyond the status quo for site contractors on this 1.2 million SF project. Their scope of work includes moving 500,000+ CY of earthwork and placing 100,000+ tons of stone. Joliet has experienced above average rain totals since construction started in March and Witech has not only met our schedule but helped keep the site in working condition for all our other trades. They have the unique ability to put Safety first while maintaining our aggressive schedule, and they are a pleasure to work with.
