Synergies between Sustainable Design and Constructability at the Pentagon

Sustainable design and constructability are two keys for efficient design and construction that are often addressed separately from each other in projects. This paper examines the integration of these two initiatives on the Pentagon renovation. The examination exposes a synergistic relationship between sustainable design and constructability. This relationship strives to efficiently utilize resources and reduce waste in the project. The integrated organizational structure and design-build performance based contracting strategies at the Pentagon have assisted in the implementation of sustainable design and constructability. Connections between the two initiatives were found at the conceptual level, system level, materials level and in the design implementation process. Importantly, the analysis of the Pentagon reveals that the potential to improve the sustainability and the constructability of a project is enhanced when the two initiatives are integrated and approached in a combined fashion.
