For engineering firms

Pile Load Testing Your Engineers Can Trust.

Pile load testing for engineering firms. Operators and field data techs trained to the Engineer of Record's (EOR's) test plan, so your engineers can focus on the engineering.

Engineering and geotechnical firms need field partners who can install test piles, run load tests, operate heavy equipment and record clean data. That leaves the engineer free to focus on analysis and design.

XCEL provides pile load testing for engineering firms, with heavy equipment operators and field data collection technicians trained in data collection per the EOR's test plan. Our record: Over 20 GW of utility-scale solar pile load testing since 2018, on projects typically 100 MW to 600 MW.

What we provide

Pile load testing support

Pre-construction test pile installation and axial tension (uplift), lateral and compression testing on fixed-tilt and tracker projects, in general accordance with the standards the EOR specifies, so the EOR can optimize pile embedment and design. Production QC testing verifies installed piles meet design loads. Pile Load Testing · Pre-Construction Testing · Production QC Testing

Heavy equipment operators and field data collection technicians

Experienced operators work under your engineers' direction. Our field data collection technicians are fully trained in data collection per the EOR's test plan, so readings, logs and photos come back complete and consistent.

Pre-drilling and test pile installation

Drilled and driven test piles, with pre-drilling through rock where needed. Rock Drilling · Pile Installation

Layout and location records

Topcon GNSS RTK layout of test locations and a location record for every test.

Pile load testing for engineering firms: when to call XCEL

Most engineering and testing firms don't keep pile drivers, drill rigs and reaction equipment in the yard, and they shouldn't have to. Firms call XCEL when:

FAQ

Questions we hear.

Do you interpret test results?

No. We install the test piles, run the tests to the Engineer of Record's plan and deliver complete field data, photos and location records. Interpretation, pile design and the client relationship stay with your firm and its licensed professionals. XCEL supplies the equipment, the people and the field execution.

Do you provide equipment operators and data collection technicians?

Yes. We provide experienced heavy equipment operators who work under your engineers' direction, and field data collection technicians fully trained in data collection per the EOR's test plan. Readings, logs and photos come back complete and consistent, recorded in your format and delivered on your schedule.

How much pile load testing have you done?

Over 20 GW of utility-scale solar pile load testing since 2018, on projects typically 100 MW to 600 MW. Major EPCs and leading tracker OEMs trust us on some of the country's largest utility-scale solar projects. Engineering firms get the same crews, equipment and data standards on every test program.

Which tests do you run?

Axial tension (uplift), lateral and axial compression load tests, in general accordance with the standards the Engineer of Record specifies, typically ASTM D3689, D3966 and D1143. We run them for both pre-construction programs and production QC testing, and the field data goes straight to the Engineer of Record.

Can you install test piles in rock?

Yes. When test piles hit rock or refusal, our own Epiroc rigs pre-drill the test locations and our pile drivers install the test piles by the approved method. Your program stays on schedule without bringing in a second subcontractor, and every test location is staked and recorded with Topcon GNSS RTK.
