The Chaffey College Library Learning Commons, located at 5885 Haven Ave. in Rancho Cucamonga, California, stands as a new focal point for academic support and collaboration on campus. Bergelectric played a pivotal role in bringing this ambitious project to life, delivering a robust electrical infrastructure to serve the facility’s dual purpose as both a library and a modern learning center.
Project Overview
Designed to foster student learning and engagement, the Library Learning Commons features advanced technology, flexible study spaces, and a welcoming atmosphere. At the peak of construction, Bergelectric’s team included 19 electricians, showcasing effective leadership and teamwork in a complex environment.
Unique Design and Construction Elements
This project was distinguished by its many unique requirements, demanding a high level of coordination and precision. The building was outfitted with a Quark Lighting Controls system, introducing advanced device integration, sophisticated zone coordination, and specialized wiring pathways. These features required seamless alignment with both architectural details and other mechanical, electrical, and plumbing (MEP) systems, elevating the complexity of the electrical installation.
Leveraging BIM for Project Success
BIM (Building Information Modeling) was integral to the project’s success. Its use enabled all trades to proactively identify and resolve conflicts, refine in-wall layouts, and accurately plan for overhead supports, deck sleeve placements, and floor boxes. BIM also supported precise underground conduit stub-ups and significantly minimized field rework, enhancing both efficiency and installation quality.
Overcoming Project Challenges
The project included several distinctive challenges. The first level was partially subterranean, complicating equipment placement and requiring careful consideration of waterproofing, wall cavity limitations, and access zones. Early coordination was critical in these areas.
Additionally, the three-level central atrium posed major design and installation complexities. This expansive open space necessitated vertically aligned systems and highly coordinated lighting layouts, with pathways carrying through multiple floors. The atrium’s visibility demanded that both functionality and aesthetics be balanced throughout the process.
Innovative Construction Practices
Bergelectric implemented several innovative practices on the project, including the use of Trimble technology, prefabricated conduit racks, in-wall rough-in boxes, shark cages, and underground duct banks. These strategies improved efficiency, reduced onsite labor, and contributed to the project’s quality outcomes.
Schedule and Budget Management
Maintaining the project schedule and budget required structured internal processes and close collaboration with the general contractor. Weekly coordination meetings allowed for review of progress, schedule shifts, and manpower planning. As the project neared completion, overlapping trades created congestion, making precise coordination and safety even more critical. Frequent communication and agile planning helped overcome challenges posed by compressed schedules, shifting lead times, and specification changes.
Low Voltage and Technology Systems
Bergelectric’s scope included a comprehensive array of low voltage systems, such as:
- Network infrastructure (backbone and horizontal cabling, teledata room buildouts)
- Audio-visual cabling (excluding HDMI and speaker wiring)
- Turnkey assisted listening systems (including Chief back boxes)
- CCTV security cabling with installation of owner-furnished cameras
Project by the Numbers
- Wire Installed: 182,273 linear feet
- Light Fixtures: 1,096
- Switches/Outlets: 1,106 receptacles and lighting control devices
The Chaffey College Library Learning Commons project represents Bergelectric’s commitment to technical excellence, innovation, and collaborative problem-solving. Through advanced planning, technology integration, and a focus on precision, the team delivered a facility that will serve students and the campus community for years to come.
