Structural Engineering & Civil Engineering

I am a licensed civil and/or structural engineer in 20 states – namely Arizona, Arkansas, California, Colorado, Connecticut, Florida, Hawaii, Illinois, Kentucky, Louisiana, Nebraska, Nevada, New Mexico, North Carolina, Oregon, South Carolina, Tennessee, Texas, Utah, and Washington. I provide expert opinion reports and testimony for structural and civil projects involving both forensic engineering and design engineering. I have conducted over 600 forensic investigations involving roof failures, wall failures, foundation issues, building envelope failure, corrosion, or other forms of damage resulting from rain, hail, wind, snow, tornado, hurricane, earthquake, lightning, fire, volcano, tropical storm, vehicle impact, construction defect, or other natural or man-made events. I have testified at depositions and trials regarding concrete roof tile wind damage, post-tensioned slab adequacy to resist punching shear, project cost estimates, wall structural adequacy to resist wind forces, horizontal and vertical discontinuities, truss repair versus replacement, and other topics.

I have structural/civil engineering and project management experience across the fields of transmission line structural design and evaluation and residential, commercial, and industrial building design, evaluation, and retrofit.  My experience includes high- and low-voltage power line support structures, tract houses, landscape structures, theaters, pharmacies, restaurants, custom homes, multi-story apartments over podium slabs, billboards and other structures utilizing wood, masonry, steel, concrete, and carbon fiber reinforced polymer. I also provide fall protection anchorage evaluation and design at industrial structures. I have designed unique structures and retrofits including a water tower seismic retrofit, a parabolic steel arch truss solar array, a tapered masonry monument, and fiber-reinforced polymer retrofits to post-tensioned concrete slabs.

I am a National Council of Examiners for Engineering and Surveying (NCEES) record-holder with Civil and Structural Model Law status. I am also the sole proprietor of Marcor Forensic and Expert Consulting. This combination of model law status and sole proprietorship equips me with the unique ability to rapidly obtain additional licensure in any state where my expertise may be required. Besides sole proprietor of Marcor Forensic and Expert Consulting, I’m the owner of Marcor Structural Expert Network PLLC, or MarcorSEN Engineering. MarcorSEN is a forensic and design firm with multiple engineers, currently offering services in Utah, Arizona, and California, but looking to expand into Texas and Washington (and other states as required).
