AOT Singapore

Code-compliant M&E contractor for FM, MCST and UPS scoring

ALPHA & OMEGA TRINITY PTE. LTD. (UEN 201215586K) is the same legal entity behind AOT plumbing, tank, pump, heater, aircon and electrical. When a UPS or building tender scores “licensed, trained, code-compliant”, this is the public stack. Full certificate scans go in the confidential pack — this page does not list a worker roster.

Why this wins the UPS line, not a slogan

Unlicensed handymen cannot sign PUB submissions, enter roof tanks under a confined-space method, or show calibrated gas meters. AOT can. Ask for the confidential scan pack with your RFQ to admin@aot.com.sg.
