Joint ASCE/BAPG Meeting - Unique Foundation Wall, Where Temporary Becomes Permanent
Presenters: Andrew Nichols
This presentation is eligible for 1 PDH.
McMahon & Mann Consulting Engineers, P.C. (MMCE) was involved in the planning, design and construction phases of a project for a planned medical office building located on the Buffalo
Medical Campus. The building was unique in that it required the cost effective design and construction of a two level below ground parking facility. MMCE provided geotechnical services
including managing subsurface explorations, providing foundation recommendations, designing a temporary shoring system which would become the permanent basement wall and providing
design support throughout construction.
Mr. Nichols will provide a brief overview of the project and the geotechnical and geological conditions encountered at the Site. He will then describe the chosen basement wall system and
discuss the cooperative effort that was developed between the owner, designers, contractors and material supplier. He will then describe in detail the design of the temporary shoring system
including specific site constraints and requirements. Followed by the sequencing effort to turn the temporary shoring system into a permanent basement wall. MMCE prepared design plans for excavation shoring that consisted of a 25-foot high sheetpile
wall with tieback supports and knee braces. The tieback design considered the proximity of the surrounding structures including the Buffalo Rapid Transit Tunnel under Main Street, the
planned new Women and Children’s Hospital east of the office building and the fact that contaminated soils had to be removed during the excavation process.
