Scope
What we test in El Paso 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 El Paso County
El Paso County sits at elevations ranging from the plains east of Colorado Springs into the foothills approaching Pikes Peak, where temperature swings between seasons — and within a single day — directly affect how concrete sets and how compacted subgrades perform over time. Expansive and variable soils across the county create real foundation risk if fill placement and compaction are not verified against specification. Active residential subdivision, commercial development along major corridors, and public infrastructure work all require defensible materials testing data to satisfy engineer-of-record requirements and local agency submittals. Our firm dispatches certified field technicians to El Paso County project sites through our Denver regional hub, covering scheduled and project-based assignments. Technicians perform ASTM-compliant fresh concrete testing, cylinder fabrication, aggregate quality testing, and soil compaction and classification work. The laboratory operates under a documented quality system, and reports are prepared for third-party review.
El Paso County soils frequently include expansive clays and variable alluvial deposits that require careful Proctor baseline testing and consistent compaction verification to meet geotechnical recommendations. Concrete placements at higher elevations and during shoulder seasons demand attention to temperature limits under ACI 305R and ACI 306R, as both hot and cold weather conditions occur within the same construction calendar.
FAQ · El Paso County
El Paso County gets late-spring freezes and summer afternoon thunderstorms — how does weather affect when and how you test concrete on our project?
Temperature at the point of discharge must be measured and recorded per ASTM C1064. When ambient or concrete temperatures fall below 50°F or rise above 90°F, ACI 306R and ACI 305R thresholds apply, and our technicians document conditions that could trigger specification-level hold actions. Cylinders are protected during initial cure per ASTM C31 requirements regardless of season, and field notes capture weather conditions at time of placement.
Our geotechnical report calls out expansive soils on our El Paso County site. What testing do you perform to verify subgrade and fill preparation?
We perform Proctor compaction curves (ASTM D698 or D1557, per specification) to establish the moisture-density relationship for each soil type encountered, then verify field compaction using nuclear density gauge testing under ASTM D6938. Soil classification per ASTM D2487 can be included to confirm fill material consistency. Results are compared directly to geotechnical report requirements and reported with the test locations and elevations needed for record documentation.
Will El Paso County or the City of Colorado Springs require third-party special inspection reports, and can your testing data support that submittal?
IBC Chapter 17 requires special inspection programs for many structure types, and local jurisdictions in El Paso County typically enforce those provisions through the building permit process. Our field testing reports identify test locations, specification references, pass/fail status relative to project requirements, and technician certification. That format is designed to integrate into a special inspection record submittal to the authority having jurisdiction without requiring reformatting.
How fast can a technician be on site in El Paso County?
El Paso County work is dispatched through our Denver, CO 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 El Paso County, CO?
Field work in El Paso County is dispatched through the Denver, CO regional hub, about 63 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large El Paso County projects.
Are the technicians you send to El Paso 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 Colorado agencies or owners require state-specific certifications, those are confirmed in the proposal.
