Building owners consider the planned maintenance as a matter of serious apprehension, and yet building owner cannot afford to tolerate their buildings to perish over a period of time. As it is undoubtedly unfeasible, and even detrimental to restore all the older buildings, everybody apprehensive with those buildings, whether as the owners, builders or the end users, ought to take a serious attention in this infinite dilemma of building. Now and then, they have a certain amount of budget to handle or cover this problem and only waiting for the liable person .
Building maintenance progression was on reservation and restoration commotion for the building of structural and components. Building maintenance envelops every part of buildings, for example, rooms, toilet windows, wall and their furniture. Building maintenance is a worldwide problem and extremely measured for the untimely route of construction that the superiority of the building can be guaranteed . Maintenance also can be referred as an operation that being done on a continuous basis to maintain the building in a safe and the best form for the everyday use. Maintenance activities cover all the building like from the top to the bottom of particular building. This commotion will identify all part of it in order to ensure that it could be used either on the structural, components and the materials holistically .

TYPES OF MAINTENANCE:
As been presented earlier, maintenance can be categorized into two groups: unplanned and planned maintenance. For planned maintenance that work that have a scheduled and carried out, i.e. daily cleaning of floor, weekly for cleaning the window and a year to check the painting of the building . Whereas for the unplanned maintenance where the work is carried out on emergency basis or when having problem in that building, for example, when lift is having problems, so maintenance needs at that particular time. There are three types of maintenance which are; corrective maintenance, preventive maintenance, and condition-based maintenance. The types of maintenance include the service maintenance that maintenance items demanded by the renter or the occupant. It also includes some emergency items. Next is what we called as a routine maintenance that includes broad or general types of maintenance to the common areas. These particular aspects are not requested by the tenant, but it is necessary in order to keep the building in excellent state.

CORRECTIVE MAINTENANCE :
Corrective Maintenance Corrective maintenance is the maintenance carried out subsequent to the breakdown that has occurred and projected to reinstate an item to a state in which it can execute its necessitated purpose. Whereas, preventive maintenance is maintenance that carried at prearranged period of time and anticipated to diminish the possibility of malfunction or the performance dilapidation of any particular item. Condition-based maintenance is defined as preventive maintenance commenced as a result of knowledge of the condition of an item from the schedule or incessant monitoring . It should be pointed out that corrective maintenance is the simplest types of maintenance approach, where building components are utilized until its breakdown. It covers all actions, which include repair of an element that has failed to a point at which it cannot execute its essential purpose. Hence, corrective maintenance can be tremendously costly because the breakdown or failure of a particular item can cause a great amount of significant damage to other elements in the building. For examples, failure of the roof might cause harm to the ceiling and the interior part of the building and the failure of an item can take place at a time which is not convenient to equally the user and the maintenance personnel. This could formulate manpower and spare parts planning exceptionally complicated.

PREVENTIVE MAINTENANCE:
On the other hand, the preventive maintenance is established to surmount the disadvantages of corrective maintenance, by reducing the likelihood of the incidence of malfunction and avoiding unexpected failure. Preventive maintenance task is done in agreement with a prearranged plan at regular, fixed intervals, which may be based for example on an operating time. There are some advantages of preventive maintenance in excess of corrective maintenance such as the maintenance could be intended in advance and executed when it is expedient to the building’s user, the cost could be diminished by avoiding the cost of significant damage, the point in time that a component of the building or the entire building is out of service, can be diminished, the health and safety of the user can be improve and the planned maintenance task are frequently very challenging in terms of spare parts and the labour cost.
