The Importance of Maintenance

In order to keep an air conditioning facility or water supply and drainage sanitation facility functioning normally and safely, it is essential that it be maintained. The cost of construction is only a part of the necessary costs for running a building (lifecycle costs), and in fact the far larger portion of such costs is incurred by maintenance and management.

The equipment, plumbing ducts and so forth each have a useful life, and periodic maintenance prolongs the useful lives of equipment and systems and prevents the facilities from becoming out of order.

Among maintenance, there are two types of inspections: one that is prescribed by law and the other that is carried out to prevent failures and protect equipment.

What is Life Cycle Cost (LCC)?

Have you heard of a building’s “lifecycle cost” or “LCC”? This term refers to the total cost of a building over its lifecycle. It includes not only the cost of its planning, design and construction, but also the cost required to maintain and manage it, and, finally, the cost of its dismantling and disposal.

As shown by the figure above, building cost is just the tip of the iceberg, and the majority of LCC is made up of maintenance and management costs.
