IS 15183 Part 1: General Principles of Building Maintenance

This part provides guidelines for maintenance management focusing on:

Key Points from Clause 4.5 (Maintenance Guides)

• Maintenance guides should be tailored for each building, especially if only a few buildings are maintained.
• Guides must consider:
  • Type of construction (e.g., RCC, masonry, steel)
  • Residual life of the building (remaining service life)

General Principles:

• Periodic inspection schedules based on building type and age.
• Preventive maintenance to extend life and reduce major repairs.
• Documentation of maintenance activities, defects, and repairs.
• Prioritization of maintenance tasks based on safety, functionality, and aesthetics.

Typical Maintenance Management Table (Example)

Formula for Residual Life Estimation (Simplified):

[ \text{Residual Life} = \text{Designed Life} - \text{Age of Building} ]

Where Designed Life depends on construction type (e.g., 50 years for RCC).

Key Concepts & Specifications

• Maintenance Types:

  • Preventive Maintenance: Scheduled inspections and servicing to prevent failures.
  • Corrective Maintenance: Repairs after faults occur.
  • Predictive Maintenance: Using condition-monitoring techniques.

• Maintenance Management Cycle:

  1. Inspection & assessment
  2. Planning & scheduling
  3. Execution
  4. Feedback & improvement

• Performance Indicators:

  • Downtime reduction
  • Cost control
  • Safety compliance

Typical Formula for Maintenance Cost Estimation

[ \text{Maintenance Cost} = \sum (\text{Labour Cost} + \text{Material Cost} + \text{Overheads}) ]
