1. O&M as the longest phase of a building’s lifecycle
After construction, buildings enter the operation and maintenance phase, often lasting decades. This phase consumes the largest share of lifecycle cost and determines real performance.

2. Why O&M is often overlooked
Many projects prioritize construction completion without a clear O&M strategy. As a result, minor defects go unnoticed and escalate into major failures.

3. The link between O&M and durability
Regular maintenance helps detect early signs of leakage, cracking, and deterioration. Timely intervention extends service life and reduces repair costs.

4. O&M and Life Cycle Cost (LCC)
Operation and maintenance costs form a significant portion of LCC. A structured O&M strategy helps stabilize long-term expenditure and avoid unexpected costs.

5. Material performance and O&M
Properly selected and installed materials require less maintenance. In contrast, unsuitable materials increase repair frequency and environmental impact.

6. O&M in sustainable construction
From a sustainability perspective, effective O&M helps to:
- Reduce resource waste
- Minimize rework and demolition
- Maintain healthy living environments
- Preserve asset value

7. Stakeholder responsibility during O&M
Owners, operators, and users all play a role in maintaining building performance. Poor coordination weakens the effectiveness of initial sustainable solutions.

8. BUMATECH’s perspective
BUMATECH designs material solutions that support efficient O&M. Appropriate materials and technical guidance help buildings retain performance over time.

9. Conclusion
Sustainable construction does not end at completion. Proper operation and maintenance are essential to achieving lasting durability and sustainability benefits.
