M&T Bank Stadium

Before construction began on the Ravens' Bank Stadium, the Maryland Stadium Authority identified three trades (concrete, mechanical, and electrical) as critical to the successful completion of the project. They went outside of the lump sum bid process to select contractors with the demonstrated ability to promote minority participation and labor harmony, while meeting the project’s goals for schedule, cost, quality and safety. Clark served as the prime contractor for the concrete foundations and superstructure on the stadium project.

One of the major construction challenges was meeting the hoisting requirements of the project. A crane study indicated that at least four cranes would be needed to most efficiently conduct framework, cast-in-place concrete and precast operations. Additionally, the cranes needed to be located inside the stadium seating area for the erection of the precast seating treads and risers. However, the poor soil conditions and high water table in the stadium site would have prohibited the use of crawler cranes at various times during the project. In order to meet these demanding project requirements, Clark’s project team, in conjunction with the Construction Manager, developed a rail-mounted tower crane system which enabled the cranes to travel inside the stadium bowl.
