Scope
What we test in Queens 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 Queens County
Queens County sits at the dense core of one of the most active construction markets in the United States. High-rise residential towers, transit infrastructure, healthcare campuses, and mixed-use redevelopment projects all demand concrete, soil, and aggregate data prepared for third-party review and project-specification requirements. Working in an urban borough means tight staging areas, coordinated site access, and no tolerance for delays caused by missed tests or disputed results. Our firm dispatches certified field technicians from the New York regional hub to Queens County on a scheduled and project-based basis, providing ASTM-compliant testing of fresh and hardened concrete, aggregate quality and gradation, and soil classification, density, and corrosivity. The laboratory operates under a documented quality system, and every report is formatted to be clear, traceable, and defensible — ready to satisfy the New York City Department of Buildings and the project record alike.
Much of Queens County is underlain by glacially deposited soils — variable fills, sands, silts, and clay lenses common to the New York City coastal plain — making thorough soil classification and compaction verification important on any project disturbing or loading native subgrade. New York City's cold winters also create meaningful scheduling pressure for concrete placement: ambient and mix temperature monitoring in accordance with ACI 306 guidance is a practical consideration for any cold-weather pour in the borough.
FAQ · Queens County
Queens projects often have variable fill and urban made-ground. How do you handle soil classification when conditions differ across the site?
Our technicians classify soils in the field using ASTM D2487 (USCS) and log material changes across sample locations. When borings or test pits reveal variable fill — common across much of Queens County — we document each stratum separately and collect representative samples for Proctor compaction testing per ASTM D698 or D1557, so density targets reflect the actual material being compacted, not an assumed soil type.
The New York City DOB requires special inspection for concrete on my project. Does your materials testing satisfy that requirement?
Special inspection for concrete under IBC Chapter 17 and the NYC Building Code requires a registered special inspection agency and technicians qualified for the specific tasks. Our field concrete testing — slump, air content, temperature, and unit weight per ASTM C143, C231, C1064, and C138, plus cylinder fabrication per ASTM C31 — produces the field data and cylinder break records (ASTM C39) that a special inspection program depends on. Confirm your TR1 filing requirements with your engineer of record.
Winter pours are common on fast-track Queens projects. What concrete testing do you provide during cold-weather conditions?
During cold-weather placements, our technicians record fresh concrete temperature at point of discharge per ASTM C1064 and can monitor ambient conditions at the pour. Concrete temperature data feeds directly into ACI 306R cold-weather concreting compliance documentation. Cylinder sets are protected and cured following ASTM C31 field-curing requirements, which is critical when ambient temperatures approach or drop below 40°F.
How fast can a technician be on site in Queens County?
Queens County work is dispatched through our New York, NY 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 Queens County, NY?
Field work in Queens County is dispatched through the New York, NY regional hub, about 11 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Queens County projects.
Are the technicians you send to Queens 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 New York agencies or owners require state-specific certifications, those are confirmed in the proposal.
