Scope
What we test in Fairbanks North Star Borough
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 Fairbanks North Star Borough
Building in the Fairbanks North Star Borough presents material challenges that most construction markets never encounter. Permafrost, extreme freeze-thaw cycles, and interior Alaska's temperature swings — from below -50°F in winter to the mid-80s°F in summer — place exceptional demands on concrete mix designs, subgrade stability, and long-term structural performance. A footing poured on inadequately tested fill or a concrete placement made without proper temperature monitoring can fail in ways that are costly and difficult to remediate once the ground refreezes. Our firm provides ASTM-compliant field and laboratory testing of concrete, aggregate, and soil for projects throughout the Borough. Technicians hold ACI and NICET certifications and operate under a documented quality system. Coverage is dispatched on a scheduled and project-based basis through our Seattle regional hub. We deliver defensible test reports that satisfy agency submittals, special inspection programs, and project specification requirements.
Interior Alaska soils commonly include frost-susceptible silts and organic materials that demand careful classification and compaction verification before and during construction — conditions where ASTM D698, D1557, and D2487 testing are especially consequential. Concrete placements in Fairbanks must also account for ACI 306 cold-weather concreting requirements across a construction season that can involve sub-freezing ambient temperatures even in shoulder months.
FAQ · Fairbanks North Star Borough
How do cold-weather conditions in Fairbanks affect concrete cylinder curing and what precautions apply?
ACI 306R addresses protection of fresh concrete in cold weather. Field-cured cylinders must be protected from freezing for the first 24 hours at minimum; standard-cured cylinders must be maintained at 60–80°F per ASTM C31. In Fairbanks conditions, our technicians document ambient and concrete temperatures at time of placement and verify that field curing enclosures meet spec requirements before cylinders are transported.
Can you perform soil testing relevant to frost heave and permafrost-adjacent subgrade conditions?
Yes. We perform ASTM D2487 classification, Atterberg limits (ASTM D4318), and gradation (ASTM C136 / D6913) — all directly relevant to identifying frost-susceptible soils such as silts and poorly graded fines common in interior Alaska. These results inform geotechnical decisions about subgrade treatment and fill selection. We do not perform permafrost-specific geothermal analysis, but our classification data supports the engineers who do.
What concrete mix design considerations should I expect your technicians to verify in the field for a Fairbanks project?
Technicians perform ASTM C172 sampling and conduct fresh concrete tests per ASTM C143 (slump), C231 or C173 (air content), C1064 (temperature), and C138 (unit weight). In cold-weather placements, concrete temperature at delivery is critical — ACI 306 sets minimum placement temperatures based on section size. All measured values are recorded in real time and included in the test report.
How fast can a technician be on site in Fairbanks North Star Borough?
Fairbanks North Star Borough work is dispatched through our Seattle, WA 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 Fairbanks North Star Borough, AK?
Field work in Fairbanks North Star Borough is dispatched through the Seattle, WA regional hub, about 1518 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Fairbanks North Star Borough projects.
Are the technicians you send to Fairbanks North Star Borough 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 Alaska agencies or owners require state-specific certifications, those are confirmed in the proposal.
