CONCORD, N.C. — Griffin Industrial Realty Inc. has unveiled plans to expand its Carolina Tradeport industrial park in Concord, a city roughly 25 miles northeast of Charlotte. Griffin acquired 22 acres of land at the site in July for the development of a 147,000-square-foot speculative building — the second within the development. The building will be located directly across from the first building, a 277,252-square-foot warehouse. Site work is scheduled to begin on the second building this month, with completion slated for May 2019. The building will feature 210-foot depth, a 60-foot speed bay, 32-foot clear heights, an ESFR sprinkler system, 42 loading docks, two drive-in doors, trailer parking and 172 auto parking spaces. The third building, which will total 136,000 square feet, is available for prelease. William Maxwell and Terry Brennan of Trinity Partners are handling Carolina Tradeport’s leasing assignment and managing the park.
