E&I contractorSingaporeEstablished 2000
Dillon Engineering Services installs, tests and maintains electrical and instrumentation systems for process plants across Singapore. We finish the way a plant needs us to finish — with every loop checked and the certificates in your hand.
We are a process electrical and instrumentation contractor. That means field devices, hook-ups, tray and cable, terminations, calibration and the testing that proves all of it works together before anyone puts feed into the unit.
Most of our work sits alongside a main contractor on a live or turning-around plant, where the constraint is rarely the labour — it is the permit, the isolation, and the sequence. We plan for that, and we document as we go so that handover is a formality rather than a fight.

We work from your loop drawings, hook-up standards, cable schedules and area classification drawings. Discrepancies are raised as technical queries before material is ordered, not after it is on site.
Take-off against the issued-for-construction drawings, then verification that glands, fittings and enclosures match the Ex protection concept for each area before anything is staged to the field.
Supports, tray and tubing first, then equipment, then cable. Work is released against permits and progressed on a plan that respects the mechanical and civil sequence rather than fighting it.
Field junction boxes, marshalling and system cabinets terminated to the wiring schedule, with continuity, insulation and polarity confirmed before any circuit is energised.
Every loop proven end to end, from the field device to the control system graphic. Trips and alarms are verified at setpoint and the results signed into the loop folder.
Punch items tracked to closure, as-built drawings marked up, and the certificate and loop folder set handed over complete. The job is finished when the documentation is finished.
Nobody on our crew starts work without a permit in hand, a briefing on the isolation boundary, and a gas test result they have seen for themselves.
Safety on a process plant is not a poster — it is a sequence of checks that either happened or did not. We work to the client's permit-to-work system, hold a toolbox meeting at the start of every shift, and stop when conditions change rather than pushing on to hold a schedule.
INSTField instrument installation, impulse line and hook-up work, junction box termination and full loop checking through to punch clearance, executed alongside the main mechanical contractor within a fixed tie-in window.
ELECRemoval of the existing motor control centre, installation and alignment of the replacement lineup, cable pulling and re-termination of motor and control circuits, insulation testing and phased re-energisation across a staged plant outage.
QA-QCInstallation of sanitary-service instrumentation on clean utility skids, orbital-compatible tubing support, calibration against traceable standards and documentation prepared to suit the client validation protocols.
Most of what we do sits inside a fence line on Jurong Island or in the Tuas industrial estates, on plants that run continuously and cannot be taken down casually.
Send the drawings, the scope, or just the problem. We will tell you what it takes and what we would need from you to start.
