Tolunay-Wong Engineers, Inc. offers a full suite of testing, analysis, and consulting services for driven pile installations. We provide expert deep foundation / construction consultancy for major oil and gas companies, nationally renowned contractors and other geotechnical engineering firms.

Our engineers are qualified and experienced in designing the most appropriate and cost-effective pile foundation system utilizing both the more traditional methods of inspection and new technology for a project. TWE has experience working with piling contractors and monitoring pile installation using the Pile Driving AnalyzerTM (PDA) in conjunction with the Case Pile Wave Analysis Program (CAPWAP) to evaluate static axialpile capacity and integrity. We specialize in providing complete driven pile deep foundation testing programs for projects of any scope and foundation type.

TWE also provides wave equation analysis (with GRLWEAP) to provide driveability studies, constructability analyses, and inspector charts to engineers and contractors in an effort to select the most efficient hammer systems and ensure proper driven pile installations.
