About Ryan Biggs | Clark Davis

Ryan Biggs | Clark Davis Engineering & Surveying, D.P.C., is one of the largest woman-owned engineering firms in Upstate New York. We provide services to architects, engineers, developers, and private and public owners.

Founded in 1973, we maintain a staff of 50 in two offices in New York State. We have both the technical ability and desire to work with both project partners and owners to develop specific solutions to diverse challenges, economic limitations and time constraints during the life-cycle of a project.

    Our Capabilities

    Structural Engineering

    At Ryan Biggs | Clark Davis, we rely on our creativity and expertise to meet each engineering challenge. Our experienced engineers collaborate with our clients from conception to completion of each and every project.

    Renovation, Repair & Restoration

    Ryan Biggs | Clark Davis specializes in the repair and restoration of masonry, concrete, wood, and steel structures. As such, we provide a complete range of structural engineering services related to the building envelope.

    Surveying & Underground utility location

    Our approach to land surveying is focused on collecting the data required for the engineering design of construction projects.  This means that our survey maps are detailed, accurate and easily integrated into the engineering design and drawing software.

    Industrial Process Structural Support

    Ryan Biggs | Clark Davis has nearly 50-year history servicing industrial clients. We have been part of several international design teams offering efficient and economical Industrial Process Structural Support services to global leaders in engineering and semi-conductor manufacturing..

    Contractor Support Services

    As Engineers, we understand that responding to technically diverse problems, economic limitations and challenging time restraints is crucial on any construction projects.

    Investigation & Inspection

    As Special Inspectors we work closely with testing agencies to provide timely, comprehensive inspections for each project. We use our expertise of the project’s structural design to provide knowledgeable inspection of all types of building materials.

    Historic Preservation

    Ryan Biggs | Clark Davis offers a complete range of structural restoration services including nondestructive testing, investigations, state-of-the-art masonry restorations, timber rehabilitation, and renovations of historic structures.

    Non-destructive Testing

    We use non-destructive testing wherever possible on projects to minimize destructive removals. Testing needs are developed as the field survey proceeds. We work to find the appropriate engineering properties of in-situ materials rather than relying on historical data.

    Our Work

    Life Sciences Center


    Ryan Biggs | Clark Davis provided the structural design for the new $93 million Life Sciences Center on the campus of Dartmouth College.
