Mr. Koslofsky has 17 years of engineering geology and construction inspection experience in the Pacific Northwest, Mountain West and Alaska. He has been trained and certified by the Society of Professional Rope Access Technicians (SPRAT) as a Level 3 supervisor and technician (highest-level reached) for the planning and implementation of rope access to perform site reconnaissance and construction inspection on difficult-to-reach infrastructure. His areas of professional expertise include geologic reconnaissance, complex site explorations for dams and levees, geologic hazard assessments, rock slope and rockfall mitigation, landslide repair work, and construction inspection and QA/QC services. Mr. Koslofsky routinely gathers data and completes geologic modeling to support issue evaluation studies and to categorize Potential Failure Modes (PFMs) for dams and appurtenant structures. He regularly provides engineering support during construction to assure compliance with contract specifications. In addition, his vast experience with drilling and instrument installations has resulted in acceptance of his credentials by the Federal Energy Regulatory Commission (FERC) for drilling projects in hydroelectric dams.

Mr. Koslofsky has served as engineering geologist on the following representative projects:
