Types of maintenance and why needed

Short answer

Maintenance types include routine, preventive, corrective, emergency, predictive, and special repairs. It is necessary because buildings deteriorate, and small defects become costly; it ensures safety, prolongs life, saves money, protects investment, maintains functionality and appearance, and meets legal requirements.

Describe the types of maintenance in a project (buildings). Why is maintenance necessary and what is its importance for already built projects?

Maintenance is the combination of all technical and administrative actions needed to keep a building or facility in a condition in which it can perform its required function safely and economically throughout its life.

Types of maintenance (buildings)

  1. Routine (day-to-day) maintenance: regular small jobs such as cleaning, painting touch-up, checking drains, lubricating doors, replacing bulbs.
  2. Preventive (planned) maintenance: scheduled inspection, servicing and minor repair before failure, e.g. repainting every 3–5 years, cleaning water tanks, servicing lifts and generators.
  3. Corrective (breakdown) maintenance: repair after a defect or failure, e.g. repairing a leaking roof or burst pipe.
  4. Emergency maintenance: immediate work to deal with dangerous conditions, e.g. after a fire, flood or earthquake damage.
  5. Predictive / condition-based maintenance: based on inspection and tests (cracks, NDT, vibration) to predict when repair is needed.
  6. Special repairs and rehabilitation: major repair, retrofitting or strengthening, e.g. jacketing of columns, waterproofing a roof, renewal of services.

Why maintenance is necessary

  • Buildings deteriorate due to weather, use, ageing, water, chemical and biological action, and settlement.
  • Without upkeep, small defects grow into major and costly repairs.
  • It keeps the building safe and healthy for the occupants.

Importance for built projects

  1. Prolongs the life of the structure and finishes.
  2. Safety: prevents failures and accidents (falling plaster, electrical faults, leaking gas).
  3. Economy: a small cost for timely work saves large repair or replacement costs later.
  4. Protects investment and property value.
  5. Functionality and comfort: services, lighting, water and sanitation work properly.
  6. Appearance and image of the building; better rental income.
  7. Reduces downtime and disruption to users.
  8. Legal and insurance compliance: fire safety, lift and electric inspections.
  9. Conserves resources and the environment by avoiding early demolition and rebuilding.
