When preparing a maintenance plan, the first question is usually not when the work should happen but what should be covered. If the work list is incomplete, the plan may still be approved, yet the omitted areas continue to deteriorate until a failure occurs.
This article lists factory maintenance items by group, together with the main inspection points and suggested frequencies, so businesses can compare them against their existing scope.

Grouping makes responsibilities clearer and prevents duplication between inspection rounds.
A common structure uses four groups: structure and building envelope, technical systems, safety and fire protection, and external infrastructure.
Inspection covers protective coating condition, corrosion at welds and gusset plates, tightness of connection bolts, and any deformation or localised deflection in trusses and purlins.
Suggested frequency: one full inspection per year, with priority given to areas exposed to moisture or chemicals.
This group produces the most failures. The checklist covers roof fasteners and washers, sheet overlaps, sealant at junction points, corroded areas, gutters and downpipes.
Suggested frequency: inspect and clean gutters before the rainy season, with additional checks after strong winds or unusually heavy rainfall.

Items include cladding panel condition, gaps at the base of walls, roller shutters, sliding doors, guide rails and operating motors.
Large doors at loading areas typically deteriorate faster due to high usage frequency.
The checklist covers main and distribution panels, busbars, circuit breakers, terminations, cable trays, earthing systems and lighting fixtures.
Thermal imaging at electrical panels is commonly used to detect abnormal heat points. Suggested frequency: every six to twelve months depending on operating load.
Items include supply pumps, storage tanks, pipework, valves, manholes, process drainage lines and wastewater treatment facilities where applicable.
Where wastewater contains oil, grease or solids, manholes and traps require shorter cleaning cycles.
The checklist covers roof extractors, wall ventilation fans, evaporative cooling units, motors, belts, mounting supports and waterproofing at roof penetration points.
Cleaning fan blades and filters directly affects ventilation performance and energy consumption.
Items include air compressors, receivers, drain traps, filters and the distribution pipework inside the workshop.
Compressed air leakage is a common source of energy waste that is difficult to detect without regular inspection.
This group covers fire pumps, water tanks, pipework, sprinkler heads, hose cabinets, extinguishers, alarm systems and emergency exit lighting.
These items are subject to statutory inspection requirements and are covered separately in our article on factory fire protection maintenance.
The checklist covers cracking, coating delamination, localised settlement along forklift routes, expansion joints and internal traffic markings.
Treating cracks early limits water and dust penetration into the sub-base.
Overhead cranes, hoists, support beams, access platforms, stairs and handrails should be checked for connection integrity, corrosion protection and safe working condition.
Secondary structures are often overlooked because they are not part of the main production line.
This group includes ceilings, walls, air conditioning, sanitary facilities, canteens and ancillary storage.
Although not directly linked to production, these areas affect daily working conditions for staff.
The checklist covers internal roads, yards, boundary walls, gates, stormwater drainage, external manholes and landscaping.
Stormwater lines should be checked before the rainy season to reduce the risk of localised flooding on site.
Not every item requires the same cycle. Groups exposed directly to weather and those related to safety generally need higher frequencies.
How to distribute these across the calendar year is discussed in our article on annual factory maintenance planning.
A checklist only becomes useful when inspection results are recorded in a consistent format across rounds.
Each entry should include location, condition, photographs and the corrective action taken. After several cycles, this data reveals which areas deteriorate fastest and should be prioritised in the budget.
Factory maintenance covers a far wider scope than initially assumed, from steel structure, metal roofing, electrical, plumbing, ventilation and fire protection through to flooring and external infrastructure.
With a complete item list matched to appropriate frequencies, businesses avoid overlooked areas and gain a clear basis for planning and cost estimation. The overall scope of a maintenance programme is described in our article on factory maintenance services in Dong Nai.
Every factory has its own function, materials and operating environment. A site survey helps define the appropriate item list and set priorities for each area.
