6 | Waagner Biro Gulf: Maintenance & Infrastructure Engineering — PREVENTIVE MAINTENANCE —

— Preventive maintenance is carried out to avoid the deterioration or failure of facilities through continuous and systematic inspection and detec- tion. A rigorous program of preventive maintenance can extend the service life of a road, bridge, underpass or civil structure. This ensures that the maximum value is realised from the initial capital investment. Additionally, regular maintenance proves more cost effective than occasional major repair. The concept of preventive bridge maintenance is built on the understanding that a program of multiple relatively small repairs and activities will keep the structure in good condition. Thereby the large expense of major rehabilitation or replacement is avoided.—

—This is the large-scale maintenance carried out to restore equipment, machines or systems to a normal operational condition. Carried out yearly or as per the manufacturer‘s notes, it includes partial or complete disassembly of facilities and assets, inspection to detect the damaged, defective or worn parts and the repair or replacement of defective or damaged parts. Equipment and systems are then reassembled, tested and trial run prior to recommencing the full operating level.—

— Corrective maintenance is, widely speaking, the repair of damaged and defective facilities, such as accident repair works, the replacement of damaged light fittings, the replacement of defected expansion joints, pothole repair on asphalt layer, block paving works and the repair of steel structures. Performed at the time of the defect or during a predetermined period, corrective maintenance is carried out to identify, isolate and rectify a fault, so that the failed equipment, machine or system can be restored to an operational condition within the tolerance or limits established for service operations.—

Waagner Biro Gulf: Maintenance & Infrastructure Engineering | 15 — MEP WORKS—

—Machines and systems must work incredibly hard to perform their designated functions within a structure. The constant stopping, starting or continual operation can wear down systems quickly and unexpectedly if proper care and maintenance is ignored or delayed. By regularly performing preventive maintenance or service, Waagner Biro Gulf maximises the life cycle of systems and guards against unexpected failure. Regular and systematic inspections can uncover leaks, rust, rot frayed wires and corroded electrical contacts before they cause further problems or system failure. In building structures, our MEP (Mechanical, Electrical and Plumbing) works include the scheduled replacement of failed lamps, the main- tenance of electrical panels and the service of fire fighting system, as well as maintaining break-glass systems in underpasses, air-conditioning systems and lighting distribution panels. We also maintain and overhaul of backup generators and UPS systems.—

switches, sensors, guide rails, guide rollers, hand rails and steps are all repaired or replaced when necessary.

— ELECTRICAL MAINTENANCE Waagner Biro Gulf‘s skilled electrical engineers have broad experience across a huge range of systems, such as main distribution boards (MDB), sub main distribution boards (SMDB), motor control centre (MCC) and light distribution boards (LDB). The engineers carry out a visual inspection, clean both external and internal parts and filters, and they trip test the circuit breakers. The tightness of cable terminations is verified, and both electrical and mechanical parameters are monitored and recorded. Of course, where necessary any defective or damaged parts are repaired or replaced before an operation check is conducted.
