Two speculative developments totaling more than 950,000 sq. ft. are on the horizon in Bolingbrook and Naperville, Ill., while Schaumburg, Ill.-based Motorola Inc. has selected a 43-acre site in Elgin, Ill., to expand its distribution efforts.

Denver-based ProLogis is developing a 450,000 sq. ft. spec warehouse in Bolingbrook in the Remington Lakes Business Center. Locally based MTI Construction Services will serve as general contractor for the building, which is slated for December completion. The building will offer 60 dock doors and parking for 195 trailers.

One month ahead of schedule, locally based FCL Builders Inc. last month completed a 400,100 spec facility in Naperville. Locally based Arthur J. Rogers & Co., an affiliate of The CORE Network, is leasing the building.

In Elgin, Motorola will lease a 292,500 sq. ft. distribution center at NorthWest Corporate Park. Milwaukee-based WISPARK Corp. owns the property, and locally based Kiferbaum Construction Corp. will serve as design/builder for the facility. Locally based Colliers Bennett & Kahnweiler Inc. represented Motorola. The company plans to move 500 employees from a site in Schaumburg to the Elgin facility, with plans for an additional 500 employees at the new distribution center in the next five years.
