Role Summary The Site Supervisor is responsible for the day-to-day site supervision and execution of Network Layer 1 installation works for large-scale data centre deployment projects. Reporting to the Site Manager, the Site Supervisor will directly supervise subcontractors and installation crews carrying out fibre optic cabling, network rack installation, rack & stack, patching and associated physical network infrastructure works. The Site Supervisor is responsible for managing the 4Ms of construction – Manpower, Method, Machine and Money (Change Management) – within assigned work fronts and ensuring daily construction activities are properly planned, resourced and executed. A key responsibility of this position is maintaining strong control of planned versus actual progress. The Site Supervisor is expected to develop daily and weekly work plans, monitor actual productivity and completed quantities, identify variances early, and implement corrective actions to maintain the project schedule. This is a full-time site-based position requiring practical fibre installation experience and strong hands-on construction supervision capability.
