Director of Operations

Mr. Meilman has over 25 years of experience in subsurface investigations and construction materials testing, and has been a Registered Professional Engineer with the State of Illinois since 1988.  He has performed numerous environmental and geotechnical investigations for commercial, industrial, and residential properties including motels, shopping malls, warehouses, manufacturing facilities, automotive service stations, office complexes and high rise buildings.

In addition Mr. Meilman routinely performs Phase II investigations at landfill facilities, properties containing underground storage tanks and hazardous waste sites.  Through his experience he has an outstanding knowledge of civil and environmental engineering, product design, geology, hydrogeology, and hydrology. 

He has developed on-site development solution that include:

  • Started a Geotechnical Engineering and Construction Materials Testing division for an established environmental company.
  • Developed and implemented company protocol for the performance of the on-site soil and concrete inspections, including the field training of the drill crews and site technicians.
  • Prepared  numerous  sub-surface investigation reports pertaining to the design and construction of the foundation systems for various types of structures, including office buildings, warehouses, residences, high-rises, etc.
  • Extensive knowledge and experience in the preparation and submittal of regulatory documentation, including conformance letters to the governing agencies, such as FEMA.
  • Extensive experience in the evaluation of the foundation/slab settlement problems, including the determination of the cause and the recommendations pertaining to the reconstruction of the failed structural elements.
  • Soil Borings. Supervised the performance of the sub-surface investigations by managing the drill crews, scheduling, client contact and field work. Responsible for the preparation of all of the soil boring reports presenting the recommendations pertaining to the design and construction phases of the structure, including the foundation system, slab and paved areas.
  • Construction Materials Testing. Supervised the field technicians in the daily tasks of the testing including the performance of soil (bearing capacity, proof-roll, compaction), concrete (slump, air, unit weight, temperature), steel (welding and bolts) and asphalt (rolling pattern, compaction ) testing.
  • Laboratory Testing. Supervised the daily operations of the construction materials testing laboratory, including the performance of soil (unconfined compression, moisture content, density, Atterberg Limits, Proctor, permeability), steel (tensile strength) and concrete (compressive strength) testing.
  • Field Testing. Highly experienced in performing the tests associated with the day-to-day operations of the construction materials testing laboratory, including the drill rig (both as a driller and a technician), soil, asphalt, steel and concrete. Performed a variety of tasks associated with Geotechnical Engineering. Some of the more unusual ones included evaluation of fill placement under below freezing conditions and deflection of the existing concrete floor slab subjected to unstable loading.
