On the majority of construction tasks performed today, expertise in a task resides only within the subcontractor actually performing the task (it should be noted that in this paper, GCs are considered in-house subcontractors for the phases of work they self-perform). One of the most fundamental trends in construction over the past 50 years has been increased task specialization. Increased levels of competition within regional markets have mandated that construction crews be as efficient as possible. As a result, most construction workers no longer perform the range of tasks associated with their trade; rather, they specialize in a narrow range of tasks using the most efficient tools, materials, and methods. For example, a carpenter might specialize in installing roof sheathing and will rarely be asked to perform all rough carpentry tasks, much less any finish carpentry work. A journey-level cement finisher will specialize in operating a motorized trowel and rarely participate in placing, screeding, or floating concrete. Construction trades persons and their foremen therefore possess deep tacit knowledge about their specific tasks that others on the site lack.
