Claremont McKenna College Sports Bowl
As part of the Claremont McKenna College further expansion efforts, the CMC Sports Bowl will feature state-of-the-art athletic fields for baseball and softball along with a track and field competition venue, lacrosse and football field, and a golf practice facility. The new sports venue will offer a variety of seating options, as well as support facilities with locker rooms, meeting spaces, and sports medicine services. The first phase also includes a parking structure and a 20-foot wide arcade that will run under Claremont Boulevard connecting the Sports Bowl to the main campus for pedestrian traffic.
For the 77-acre site which includes 14 individual ground-up developments, several initial safety challenges were identified, particularly related to the team’s street work and congested work areas around heavy equipment.
Street work not only involved the excavation and construction of a 3,500-square-foot tunnel going across Claremont Boulevard, but also significant street improvements. These improvements include the addition of Class IV bike lanes, new streetlights, traffic signals, landscaping, and the undergrounding of seven Southern California Edison lines along Claremont Boulevard.
Additionally on Claremont Boulevard, the KPRS team is running site power, new Gold State water lines, and new SoCal Gas lines for the Sports Bowl. Within the Sports Bowl there are multiple operations occurring simultaneously due to the sequenced schedule, including grading, excavation, a substantial concrete scope, and tenant improvement portion of work. The amount of overlap increases the complexity of maintaining a safe work environment.
To mitigate these risks, the team implemented and engineered a multiphase traffic control plan, which includes a phased 10-month street closure. This closure has been critical in allowing the team to carry out street-related work safely and efficiently. For onsite operations, they have established delineated controlled access zones for grading, excavation, and other heavy equipment activities to further enhance safety. Additionally, they maintain dedicated walk paths between each structure to keep trade partners clear of heavy equipment.
