  • D Michael Holloway, Consulting Engineer : ( 01/12/2012 - Present )
    • Proprietor

    • Mike has specialized in onsite engineering and field testing services to investigate and solve complex design and constructibility problems. Assignments often involve a steep learning curve to resolve a critical path situation. His technical knowledge and practical experience help project teams construct foundations as bid. Expertise in design, construction, value engineering, forensic investigations, and expert services has been focused on assignments nationwide and abroad. He has played key roles in delivering major design/build transportation and infrastructure projects throughout his career.

      Specialties: Deep Foundations (design, field testing, construction, verification); Forensic Engineering (consultation and expert services); Instrumentation (monitor as-built behavior and mitigate problems); Design-Build Projects (infrastructure bridges and marine facilities); Soil-Structure Interaction (static and seismic loading)
  • Braun Intertec Corporation : ( 05/01/2023 - 16/06/2023 )
    • Director, Deep Foundations

    • Led Deep Foundations Group providing specialty services to support internal and external clients, delivering comprehensive solutions to foundation engineering design, testing and construction problems nationwide.
  • InSituTech : ( 01/03/1982 - 01/10/2009 )
    • Principal

    • Mike has maintained an independent consultancy for much of his career.  He utilizes state-of-the-art tools and knowledge to solve problems of engineers, builders and owners of major heavy-construction projects.  Ideally, these services are provided from the outset of a major project, but all to often he is called in to troubleshoot unforeseen conditions or disputes between project stakeholders.
      He founded InSituTech, the San Francisco Bay Area firm that specialized in applications of the Pile Driving Analyzer, Cone Penetrometer Testing (CPT), and other in situ testing methods.  Other work has included vibration and noise monitoring and ground/structure instrumentation applications.  Forensic services were needed on a number of projects where conflicts between parties arose. He is adept at finding engineering and construction solutions that resolve problems and avoid contract disputes.  Expert advice and testimony have also been applied in the investigating  foundation failures, addressing design/construction issues in dispute, and assessing the safety of earthen structures. 

      Pile Driving Analyzer (PDA) technology is used to investigate foundation constructability issues and confirm that foundation performance criteria are met without jeopardizing structural integrity.
      Insitu, laboratory and field test results allow thorough evaluation of the geotechnical design and foundation construction concerns.
      Effective instrumentation monitoring programs are applied to assess behavior of the facilities being built, and to mitigate disturbance of the neighbors.
      Remedial strategies to help stakeholders resolve conflicting issues, enabling the project team to achieve their objectives as designed/bid. He has provided expert consultation, forensic investigation and courtroom testimony in support of owners and builders across the US.

  • Woodward-Clyde Consultants : ( 12/01/1974 - 15/03/1982 )
    • Senior Project Engineer

    • Worked on major assignments in earthquake engineering, foundation engineering, and arctic civil engineering during my time with WCC. Earthquake engineering work included design studies for the South Texas Project and the San Francisco Ocean Outfall Project. Foundation engineering work included dams and levees, pipelines, and marine facilities, including Locks & Dam No. 26 near Alton, IL., offshore platforms, and port terminals.
