The key challenge in the CRJDA project was managing the complexity of integrating multiple systems within a non-standard architectural design while maintaining tight construction schedules. The building's curved forms, lack of typical floor layouts, and complex mechanical, electrical, and plumbing (MEP) systems posed significant coordination challenges. Additionally, the facility required features commonly found in detention facilities, which had to be seamlessly incorporated without creating a harsh or institutional feel, as the primary purpose of the building is rehabilitation for children.
Compounding this was the fact that this project marked the first design-build contract for Magil Construction, as well as the first joint venture with Tisseur, another general contractor. Both companies had to rapidly adapt to new roles, learn to collaborate effectively, and leverage their respective strengths while addressing each other's weaknesses. This partnership demanded a steep learning curve in optimizing processes, sharing resources, and aligning management strategies.
Moreover, the fast-track nature of the design-build contract meant that construction began while portions of the design were still being finalized. This required intricate planning and real-time coordination across teams, all while ensuring the project remained on schedule and within budget. Balancing these logistical, technical, and collaborative challenges was essential for the project’s success.
Magil-Tisseur addressed the CRJDA project’s challenges through a comprehensive, technology-driven approach that managed complex design elements and the fast-track nature of construction. By developing a fully federated 3D BIM model integrating architectural, structural, and MEP systems, the team detected and resolved over 2,800 clashes early on. Ongoing use of BIM and VDC enabled real-time coordination, allowing the team to promptly address evolving design and construction issues, minimizing on-site conflicts and keeping the project on schedule.
Early involvement of key contractors, particularly those handling mechanical and structural systems, was crucial. They produced high-detail models for fabrication and coordination, which were integrated into the BIM platform. With access to collaborative tools like BIM 360 and Revizto, 66 users from 11 companies worked together in real-time, ensuring instant access to design updates, clash detection, and construction sequences. Frequent automated clash detection ensured seamless coordination across systems.
Additionally, quantity extractions from BIM models allowed precise tracking of materials and work progress. Surface finishes, concrete and excavation volumes, and MEP duct lengths were quantified to verify compliance with specifications and manage supply chains. For example, the brick walls contractor invoiced based on linear meters of walls completed monthly, tracked in the field using Revizto on tablets, ensuring accurate expense control.
By integrating advanced technologies, fostering early contractor involvement, and utilizing real-time collaboration, we resolved the project's challenges by enhancing coordination, reducing errors, optimizing efficiency, and effectively managing costs within the constraints of the fast-track schedule.
