Construction is expected to be completed by the end of the year on an over 300,000-squarefoot distribution center on a 43-acre site in Merrimack.

The Boston office of commercial real estate developer Trammell Crow Company and JV partner Diamond Realty Investments recently acquired the site for construction of the Class A industrial facility planned at 50 Robert Milligan Parkway in Merrimack after receiving $32.6 million in financing from Santander Bank.

The 323,750-square-foot facility include a rear-load facility with 53 dock doors and 2,000 square feet of office space. The site is adjacent to Route 3 and the F.E. Everett Turnpike.

Project partners include architectural firm Macgregor Associates of Vinings, Ga., general contractor RC Andersen of Fairfield, N.J., and civil engineering firm Bohler, which has an office in Boston. Santander Bank provided the construction loan, and CBRE is handling the marketing and leasing for the facility. — JEFF FEINGOLD
