Panattoni Development Co. has begun phase I construction at Pinnacle Park West, an 880-acre business park on Interstate 30 just west of the Dallas Central Business District. Panattoni's Pinnacle Park project is a two-building, 1.045 million-square-foot distribution facility. The smaller of the two buildings will deliver February 2004. Jon C. Napper, a senior partner with Panattoni, said "recently Pinnacle Park absorbed 600,00 square feet in one transaction, which created the opportunity for us to start construction on this project."
