How We Work
From Request to Handover
We apply the same flow to routine daily work and major projects alike — so that quality and safety never depend on who happens to be doing the job.
Work Request
A Work Order or client instruction is received and its technical requirements reviewed.
Planning
Work method, manpower, material, and equipment requirements are determined, and risks assessed.
Permit & Safety
Work permits are arranged, a toolbox meeting held, and protective and safety equipment prepared.
Execution
Work is carried out by certified teams under quality and safety supervision in the field.
Handover
Testing, documentation, work reports, and handover to the client.
Capability
Resources in the Field
Services only mean something when the people and equipment are ready. TCM teams are based at head office and across operating areas from Riau and Jambi to West Java and East Java.
