Virgil Christoffer, P.E.

With 25+ years of electrical engineering experience we provide consultation and analysis of MEP, Industrial, and Commercial electrical power distribution systems. We are currently licensed in Texas and Colorado. We provide Electrical System Analysis, reports and studies to include short circuit, motor control center, motor feeders, branch circuit/feeder, and commercial loads. Our professional engineering software is used to provide fast and accurate analysis with the highest reliability. While we only provide system analyses and studies, our practical experience extends to all phases of electrical estimating, engineering design, field engineering and installation. From initiation of preliminary design concepts to final construction. We're experienced in low and medium-voltage power distribution up to 15 kV. We can work directly with owners, architects and engineers during the conceptual designs of buildings in the preliminary and final stages. We’re capable of leading engineers, designers, and electricians as project manager from initial concepts to job completion. Experienced with job coordination between electrical design and other disciplines for the installation of necessary electrical equipment and circuits. Peer review of your projects is an important part of any engineering project. A plans checker or “Another set of eyes” can find mistakes early before the E&O Insurance is needed. Some reviews can take a few minutes or several hours in the DD stage but many, many hours after the project is released as CD. We can make that happen and save you the headache of finding your mistakes too late to retrieve and correct. Remember, your projects aren’t complete until you’ve made that final check.

TFL/PDMG leader for Public Assistance (PA); Technical Resource Team Member (TRT/BAT) responsible for review and validation of disaster related damages and funding of repairs for flood and wind-damage in categories B through G. Reviewed Projects for clarity and completeness and adherence to FEMA policy (PAPPG), NEC and Alternative Procedures. Conducted thorough analysis of disaster damage photos from site inspections for repair/replacement scenarios to create DDDs and SOWs for Project Reports. Utilized MEANS software to estimate (CRC/ CEF) costs for 50% analysis of building replacements, electrical system repairs.
