Scope
What we test in Douglas County
Concrete testing services
Fresh concrete sampled and tested at the pour — slump, air content, unit weight, and temperature — with cylinders and beams cast on site and broken in the laboratory on the schedule your specification calls for.
ASTM C172ASTM C143ASTM C231ASTM C173ASTM C138ASTM C1064ASTM C31ASTM C39
Aggregate testing services
Gradation, fines content, specific gravity and absorption, unit weight, abrasion resistance, and stockpile moisture for concrete, base course, and backfill aggregates.
ASTM D75ASTM C136ASTM C117ASTM C127ASTM C128ASTM C29ASTM C131ASTM C566
Soil compaction and density testing
Standard and modified Proctor curves in the laboratory and in-place density by nuclear gauge on every lift, so fill, subgrade, and trench backfill are documented against the specified percent compaction.
Soil classification and index testing
Sieve and hydrometer gradation, Atterberg limits, moisture content, specific gravity, and USCS classification for earthwork acceptance, select-fill verification, and geotechnical reports.
ASTM D6913ASTM D7928ASTM D1140ASTM D4318ASTM D2216ASTM D854ASTM D2487
Soil corrosivity testing
pH and electrical resistivity of backfill for MSE walls, pipelines, and buried structures, reported against the specification limits for metallic and geosynthetic reinforcement.
Special inspection (IBC Chapter 17)
ICC-certified special inspectors for reinforced concrete and soils, reporting to the building official alongside the materials test results, so one agency covers both requirements.

Local conditions
Construction materials testing conditions in Douglas County
Douglas County sits at the core of one of the Great Plains' most active construction markets, where projects range from large-scale commercial and industrial development along the I-80 corridor to residential subdivisions pushing into the surrounding uplands. Nebraska's freeze-thaw cycle — with ground frost depths that regularly influence both pavement design and slab-on-grade work — makes concrete mixture verification and placement-temperature documentation more than a formality; they directly affect long-term performance. At the same time, the region's mix of loessial and glacially deposited soils means subgrade behavior can vary across a single site, making compaction verification and soil classification essential to foundation and pavement design confidence. Our certified field technicians dispatch to Douglas County projects through our Kansas City regional hub, performing ASTM-compliant fresh concrete testing, cylinder fabrication, aggregate evaluation, and full soil compaction and classification programs. Every result is documented under a structured quality system and delivered in reports built to support your project record, agency submittals, and design team review.
Nebraska's loess-dominant soils are highly moisture-sensitive, meaning that Proctor moisture-density relationships (ASTM D698, ASTM D1557) and nuclear or sand-cone density verification are critical controls during earthwork — particularly when seasonal precipitation creates rapid changes in in-place moisture content. Concrete placements during the extended cold-weather window common to the Omaha metro should be documented with placement temperatures and mix verification in accordance with ACI 306 to protect early-strength gain.
FAQ · Douglas County
Douglas County winters are long — can you perform concrete testing during cold-weather pours, and what documentation does that require?
Yes. During cold-weather placements, our ACI-certified field technicians record concrete temperature at point of discharge per ASTM C1064, verify that mixtures meet the temperature minimums specified in ACI 306R, and document admixture use where relevant. Fabricated cylinders (ASTM C31) are protected from freezing until transport, and all temperature readings are captured in the field report tied to the specific placement event.
Nebraska loess is notorious for moisture sensitivity — how does that affect the compaction testing program on my Douglas County site?
Loessial soils respond sharply to moisture variation, so moisture-density relationships established by Proctor testing (ASTM D698 or ASTM D1557, as specified) are the essential baseline. Our technicians verify in-place density against that baseline using nuclear gauge (ASTM D6938) or sand-cone (ASTM D1556) methods, and field moisture is checked simultaneously so your earthwork superintendent has the data needed to adjust before compaction deviates from specification.
How far in advance do I need to schedule a technician for a Douglas County project, given your dispatch location?
Coverage for Douglas County is dispatched through our Kansas City regional hub. We recommend scheduling at least 48 to 72 hours ahead for planned testing events such as subgrade proof rolls, structural concrete pours, or aggregate sampling. We are unable to promise same-day response. Contacting our dispatch team with your project schedule early in the construction sequence allows us to coordinate coverage efficiently across multiple trades or pour events.
How fast can a technician be on site in Douglas County?
Douglas County work is dispatched through our Kansas City, MO regional hub. Scheduled visits are set up by phone at (346) 420-5425; multi-day placements and full-time project assignments are scheduled through a proposal request.
Which office covers materials testing in Douglas County, NE?
Field work in Douglas County is dispatched through the Kansas City, MO regional hub, about 166 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Douglas County projects.
Are the technicians you send to Douglas County certified?
Yes. Concrete technicians hold ACI Concrete Field Testing Technician Grade I; soils and laboratory technicians hold NICET Construction Materials Testing certifications; special inspection is performed by ICC-certified special inspectors. Where Nebraska agencies or owners require state-specific certifications, those are confirmed in the proposal.
