Yes. Energy is our largest sector (320+ jobs), including multiple power-plant projects for Energy China (Thailand) and substations for Siemens Energy. Typical work: seismic integrity, dynamic and static load tests, plate bearing tests and soil resistivity (ERT). See solar farm pile testing.
What ground testing does a data centre need?
Typically soil borings for low-settlement foundation design, soil electrical resistivity (ERT) for earthing design, field density tests to control fill, and pile tests, subject to each project's specifications. SPN references include BDC Data Center, NTT BKK3/BKK4 and CP Digital Valley.
Can I get a company profile or reference list?
Yes. Ask via LINE @spnth or info@spnth.com and we will send our company profile and references close to your project type, without disclosing confidential client information.
Where do the figures on this page come from?
From SPN's internal field-job records for September 2024 – October 2026, counting completed jobs only. Projects before 2024 come from the company profile. Industry grouping is based on project names, so per-industry figures are approximate.
