Collaboration Opportunity Breaks Work Silos and Unifies Teams

Architecture, engineering, and construction (AEC) professionals are not only passionate about the projects they are assigned to, but also their specific field of work. While individuals may focus on the work in front of them and their design or engineering, understanding how their decisions affect team members’ work is critical for the projects’ and ISG’s success.
