Our industry experts discuss current issues affecting engineering, investigation, and construction services to critical infrastructure markets.
Dennis Abel, PE, chief engineer, discusses the implications of the Revision H standard on the tower industry one year since its October 2017 publication. Officially titled “ANSI/TIA-222-H: Structural Standard for Antenna Supporting Structures and Antennas and Small Wind Turbine Support Structures,” the standard, which became effective January 2018, provides guidance on minimum load requirements and design criteria. Revision H creates changes relating primarily to wind loading, existing structures, steel and concrete strengths, seismic analyses, mount analyses, and inspections and mappings.
Armita Mohammadian, PhD, PE, discusses FDH Infrastructure Services’ nondestructive testing (NDT) capabilities and the partnerships that drive them. FDH is a pioneer in the research and development of NDT methods involving dispersive wave propagation. The company was founded in part on its unique NDT methods for determining the length of unknown bridge pile foundations. Since then its proprietary methods have been applied to dams, levees, towers, and wind turbines, among other structures and foundations.
Steven R. Strickland, director of construction management, provides insight on American concrete production, the best kinds of sand for certain projects, and his take on the realistic future of sand use. Mr. Strickland was invited to be part of an industrywide AEC podcast on Building a Greener Future.
