Gateway's engineering technicians provide construction-phase observation and testing to verify the quality of construction as dictated by the project plans and specifications. In addition to foundation excavation observation; field testing of soil placement and compaction; field testing of structural concrete and reinforcing grout and mortar; concrete and asphaltic pavement subgrade and placement, these technicians provide years of on-site experience to guide the Contractor in successfully completing the work, and seeing that the owner gets a quality facility.

He is also responsible for the day-to-day scheduling and coordination of Gateway's technician staff and construction services.
