context_page_description: Patrick MacLeamy, FAIA, LEED AP, is an American architect who is chairman of buildingSMART International. Previously, he served as Chairman and CEO of HOK, a global architecture, engineering and planning firm. MacLeamy is the author of the book Designing a World-Class Architecture Firm: The People, Stories and Strategies Behind HOK, published by Wiley in April 2020. The book tells the history of HOK, one of the largest design firms in the world, and draws lessons from it intended to help other architects and creative services professionals improve their own practices.
  MacLeamy has served as an industry advocate for the need to leverage new technologies and collaboration tools to improve the practice of architecture. As a founder and chairman of buildingSMART International, MacLeamy has advanced the global implementation of building information modeling to improve the quality and efficiency of the architectural design process. He also supports the establishment of nonproprietary and interoperable standards for the exchange of data in the design and construction industry.

  MacLeamy has served as an industry advocate for the need to leverage new technologies and collaboration tools to improve the practice of architecture. As a founder and chairman of buildingSMART International (formerly the International Alliance for Interoperability), MacLeamy has advanced the global implementation of building information modeling (BIM) to improve the quality and efficiency of the architectural design process. He also supports the establishment of nonproprietary and interoperable standards for the exchange of data in the design and construction industry.
  MacLeamy established a concept, commonly referenced in the design and construction industry as the MacLeamy Curve, to illustrate the escalating cost of design modifications as a project team progresses in the design process. His time-effort distribution curves "are among the most oft-cited sources for researchers interested in mainstreaming building information modeling (BIM) implementation in the architecture, engineering and construction (AEC) industry."
