Deconstructable and Reusable Composite Slab
Mark D. Webster
Mark D. Webster, PE and LEEDTM Accredited Professional, is a Senior Staff
Engineer in the Boston-area office of Simpson Gumpertz & Heger Inc. (SGH).
Mr. Webster has seventeen years of experience in the design, analysis, and
investigation of concrete, steel, masonry, and wood structures, and is a
registered professional engineer in California and Massachusetts. His lifelong
concern for the environment has led him to investigate the ways he can incorporate
the concepts of sustainable design into structural engineering practice.
This work has made him a leading authority in the field. He has written and
lectured on topics such as the practical measures structural engineers can
take to improve the environmental performance of their designs and the life-cycle
environmental impact of building structural systems. He is vice-chair of
the LEED Materials & Resources Technical Advisory Group and a founding
member and Secretary of the Structural Engineering Institute’s Sustainability
Committee. He received a M.S. and B.S. from the University of
California, Berkeley and a B.A. degree from Haverford College.
Dirk M. Kestner
Dirk M. Kestner, PE, is a LEEDTM Accredited Professional and a Staff Engineer
in the Boston-area office of SGH. Mr. Kestner has been involved in
facilitating sustainability of the built environment throughout his career. His
interest and appreciation for the importance of resource conservation and
reuse began during his graduate research where he studied applications for
recycled crushed concrete aggregate. More recently he has been involved
in multiple projects seeking LEED® ratings, during both the schematic
and construction administration phases. He is the founding Chairman
of the Structural Engineering Institute’s Sustainability Committee,
has authored papers on the topic, and recently organized and moderated a
half-day pre-conference workshop prior to SEI’s annual convention which
focused on the structural engineer’s role in sustainable design. Mr.
Kestner received his M.S.E. in Structural Engineering from The
University of Texas at Austin and his B.S. in Civil Engineering from Cornell
University. Mr. Kestner is a registered professional engineer in the state
of Georgia and a member of the American Institute of Steel Construction and
American Society of Civil Engineers.
James C. Parker
James C. Parker, PE, received his M. Eng. in Structural Engineering from
Cornell University and his B.S. in Civil Engineering from the University
of Cincinnati. He joined SGH in 1985 and is a Senior Principal. He has extensive
experience in the structural design of new buildings and renovations to existing
facilities. He has performed seismic assessments of structures in areas of
significant seismic risk worldwide. Exposure to both new construction and
to building-related problems during investigations enables Mr. Parker to
bring creative solutions to the design process that reflect a realistic understanding
of the performance of buildings. Mr. Parker is a registered professional
engineer in nine states and a member of the American Concrete Institute,
the American Society of Civil Engineers Seismic Rehabilitation Standards
Committee, Boston Society of Civil Engineers, and the Council of American
Structural Engineers Executive Committee and Guidelines Committee.
Matthew H. Johnson
Matthew H. Johnson, PE, received his M.S. in Structural Engineering and
his B.S. in Civil Engineering from Ohio University. He joined
SGH in 2004 and is a Senior Project Manager for the firm. Mr. Johnson concentrates
his experience in the structural design of new building projects with a specific
interest in efficiently designed framing systems for unique architecture
and specializes in coordinating the different SGH expertise need for complicated
design projects. Additionally, he has experience in evaluation, analysis,
and adaptive reuse of existing structures. He has participated in the
analysis and design of reinforced concrete, structural steel,
timber, fiberglass, and masonry structures. Mr. Johnson is a registered professional
engineer in Massachusetts and a member of the American Society of Civil Engineers,
Boston Society of Civil Engineers, American Institute of Steel
Construction, Boston Society of Architects, and New York Architectural League.
