Excavation Shoring Design






Construction contractors and owners throughout the Northeast and Mid-Atlantic states repeatedly turn to McMahon & Mann to assist them in designing excavation shoring for bridge approaches, abutments and piers, building basements, parking garages, sewers and pump stations. Some of our projects have required us to design excavation support in rivers, such as the Niagara, Genesee and Chadakoin, in New York State. Clients include large general contractors for highway and bridge projects to specialty geotechnical contractors.
