The SPAX difference
Engineering that endures
Every SPAX project is backed by Singapore-registered Professional Engineer certification, BCA ME3 Solar Workhead compliance, and an engineering-firm QMS — not an installation quote.
What we bring
BCA ME3 workhead
Singapore's highest solar contractor certification, mandatory for government and institutional projects.
PE-stamped drawings
All structural and electrical drawings certified by Singapore-registered Professional Engineers.
Integrated EPC
Single-contract responsibility from design through commissioning eliminates coordination risk.
