Clark Construction

As the fourth building in the Chicago Convention Center Campus, the West Hall is the largest LEED certified building in the country.  The Expansion involved adding approximately 459,000 SF of exhibition space, 140,750 SF of meeting/banquet space, a 103,750 SF column-free ballroom as well as associated food and support service spaces. The addition also required connecting the existing McCormick Place complex to an existing pedestrian bridge and modifying an existing parking garage and conference center. In addition, the new facility necessitated designing an elevated service roadway connecting the existing truck marshalling facility at the South Hall and exhibition center to the new truck dock facility at the West Expansion.  Design and construction of the building on a fast track required an unprecedented degree of communication and cooperation between Clark, the architect and the owner/operator, the Metropolitan Pier and Exposition Authority (MPEA), as well as the City of Chicago and its many regulatory agencies. The project required nearly 250 separate permits for work ranging from lane closures to the dismantling and reconstruction of an historic façade to the main building permit.  This massive project is Clark’s largest on record, and was successfully completed within budget and 4 months ahead of schedule.  

300 North LaSalle is a pre-certified LEED CS Silver project ultimately seeking Gold Certification from the U.S. Green Build Council. This building is located on the west side of LaSalle Street on the north bank of the Chicago River.  The project includes three (3) floors of below grade parking, seven floors of mixed use parking, mechanical, retail and conference center floors, fifty-two (52) floors of office space and two floors of mechanical and elevator levels.  The support of excavation is an internally braced sheeting system supporting excavations over 45 feet deep.  The structure consists of concrete caissons, grade beams and foundation walls, concrete 

core and shear walls and structural steel framing and concrete slabs on metal deck for the fifty nine (59) upper floors.  The façade of the building is primarily a highly detailed curtainwall system with stainless steel accent covers incorporating metal panel buttresses at the top of the building as well as precast concrete panels adjacent to an existing office building on the west elevation.  Rising over 800 feet, the building will be one of Chicago’s tallest upon completion.
