A New County Jail, Tested From the Ground Up

Midland County is replacing its aging jail complex with a new detention facility in Greenwood, near the intersection of County Roads 110 and 1140. The project is valued at approximately $155 million and delivers a 230,000 square foot facility designed to house approximately 800 inmates.

Magrym Consulting provided construction materials testing and inspection services for the full build. Our scope covered field and laboratory testing of soils, concrete, and masonry, along with on-site inspection and documentation of construction activities for conformance with the approved plans, project specifications, and applicable standards.

Keeping Quality Assurance in Step With a Fast Public Build

A facility of this size runs several trades at once. Earthwork, structural concrete, and masonry walls move on their own schedules, and every one of them needs a technician on site when the work happens, not the day after. A missed test is a gap in the record the county relies on.

Because this is a public facility, the documentation has to hold up beyond the job trailer. Every field test and lab result needed to be traceable to a location, a date, and a specification requirement, and reported quickly enough that the contractor could act on it.

Multiple trades in parallelSoils, concrete, and masonry work overlapped across a large footprint, each with its own testing frequency.
Public accountabilityCounty stakeholders needed a clean, traceable record of conformance for every phase of construction.
Reporting speedResults had to reach the contractor fast enough to keep pours and placements moving.
