As notable consumers of energy, with a tangible responsibility for clinical outcomes, healthcare facilities are at the forefront of sustainable design. Research correlates interdisciplinary teams with higher LEED rating and improved schedule performance, which favor more integrated organizational structures such as design-build. Specialty contractors, specifically the mechanical contractor, are becoming key participants in the early design phases of healthcare projects. This paper explores the relationships between early specialty contractor involvement in design and building system performance outcomes, using a comparative case study between design-build and CM at risk hospital projects. Due to similarities in size, scope, owner type and other factors in the selected cases, relationships are highlighted at the building system-level between the design responsibility offered to the mechanical contractor and project performance. Performance metrics under comparison in both cases include schedule and cost growth, safety statistics and projected yearly energy savings. The results indicate that tracking outcomes at the building system-level can assist in predicting project-level outcomes in a design-build organizational structure, suggesting connections between contractor design responsibility, HVAC system performance and jobsite accident rates.
