Job description
Maintenance and Repair Workers, General
Job purpose
To keep machines, mechanical equipment and building structures in working order by carrying out preventive maintenance, diagnosing faults and effecting repairs across several trades — mechanical, electrical, plumbing, carpentry and welding — so that plant and premises remain safe, efficient and available for use.
Skills
- Skilled knowledge across two or more maintenance trades: machines and tools and their repair, building materials and methods, and applied measurement for setting out and dimensional checks. Reads blueprints, schematic diagrams, repair manuals and parts catalogues. A post-secondary certificate is held by most incumbents and a quarter are educated to secondary level, with one to two years of training alongside experienced workers, often through a recognised apprenticeship.
- Works face to face and by telephone with supervisors, colleagues, equipment users, suppliers and contractors, establishing what has gone wrong, explaining what a repair requires and will cost, and negotiating access and downtime. Trains maintenance staff and subcontractors in methods and safe working, and handles disagreements about delay or standards.
- Diagnoses mechanical, electrical and structural malfunctions by inspecting, operating and testing equipment and by working through drawings and manuals, then determines whether to repair, replace or fabricate a part. Judgements are made under time pressure with equipment out of service, and an incorrect diagnosis has consequences for plant and for the people using it.
- Plans and lays out repair work from drawings, estimates the cost and materials for a job, and schedules preventive maintenance around operational demand while responding to breakdowns. Determines tasks and priorities largely without direction.
- A skilled manual role calling for dexterity and tool sense: dismantling and reassembling machines with hoists, cranes and hand and power tools, aligning and balancing installed equipment, fitting pipework, wiring and electronic components, operating machine tools and welding equipment, repairing roofs, floors and woodwork, and driving vehicles and mechanised equipment.
Responsibilities
- No formal line management, but trains and manages maintenance personnel and subcontractors on the work in hand, and is answerable for their working practices and for the safety of workers and building users affected by the plant maintained.
- Orders parts, supplies and equipment from catalogues and suppliers, estimates the cost of repairs, and records the cost of work done. Commits expenditure within limits set by others and holds no budget.
- Substantial responsibility for the condition and availability of production and building plant — motors, drives, boilers, heating and ventilation systems, pipework, wiring and fabric — and for a stock of tools, testing instruments and spare parts.
- Keeps maintenance records of work carried out, parts used and costs, and produces specifications telling others how equipment and structures are to be assembled, modified or maintained. Accuracy supports the maintenance history later decisions rest on; the format is set by others.
Effort required
- Concentrated diagnostic attention on faults whose cause is not apparent, combined with exact working to specification, frequent decisions during a job, and the pressure of returning equipment to service. Pace is partly set by the equipment itself.
- Accountability for the safety of others and for plant that must not fail is a steady pressure, and there is periodic friction with users and contractors over delay and access, some of it with angry people.
- Physically demanding throughout: standing and walking for most of the working day, with bending, twisting, kneeling, crouching and stooping to reach equipment, sustained hand and arm work with tools, repetitive movement, and manual handling of parts and materials.
Working conditions
- Work moves between environmentally controlled interiors, unheated plant and workshop areas, and outdoors in all weather, with periods in enclosed vehicles or equipment. Exposure includes hazardous equipment and conditions, contaminants, very hot and cold temperatures, distracting noise, cramped spaces and awkward positions, work at height, and minor burns and cuts; common protective equipment such as safety footwear, gloves and eye and hearing protection is worn. Much of the work is done in close proximity to others.
- Most incumbents work a regular established schedule, but a quarter are on irregular patterns that shift with production demands, weather or contract, and working weeks beyond the standard are the majority experience. The postholder decides how the work is done and in what order to a considerable degree, within safety rules, manufacturers' specifications and the priorities of the operation.
