Schedule Showing Planned Maintenance- Preventive And Corrective

Introduction

The main reason for a maintenance plan is that it is the most cost-effective way to maintain the value of an asset. The advantages of a plan are: the property is organised and maintained in a systematic rather than ad-hoc way; building services can be monitored to assist their efficient use; the standard and presentation of the property can be maintained; subjective decision making and emergency corrective maintenance are minimised. When buildings are neglected, defects can occur which may result in extensive and avoidable damage to the building fabric or equipment. Neglect of maintenance can also give rise to fire and safety hazards, which could result in building owners being found legally liable for any injuries.

This paper is based on analysing estimated life cycle cost of the maintenance program for this particular building and any recommendations there may be as to time frames and intervals of maintenance. The cost of fire alarm system survey is estimated at £600 + VAT per annum. The cost of Electrical system survey is estimated at £700 + VAT per annum. All prices are estimates and are susceptible to fluctuation over time due to inflation and a variant in company's prices. All maintenance of the exterior should be completed at the same time to lower cost and inconvenience to the buildings users. The cost of Windows survey is estimated at £500+VAT. The cost of Interior maintenancesurvey is estimated at £300+VAT.

Schedule- Planned Maintenance (Preventative And Corrective)

Corrective maintenance refers to action only taken when a system or component failure has occurred. It is thus a retro-active strategy(Blacker, 2010, pp. 105-109). The task of the maintenance team in this scenario is usually to effect repairs as soon as possible. Costs associated with corrective maintenance include repair costs (replacement components, labor, consumables), lost production and lost sales. To minimize the effects of lost production and speed up repairs, actions such as increasing the size of maintenance teams, the use of back-up systems and implementation of emergency procedures can be considered. Unfortunately, such measures are relatively costly and/or only effective in the short-term. For example, if heat exchanger tubes have leaked due to pitting corrosion and production must proceed as a matter of urgency, it may be possible to plug the leaking tubes on a short-term basis.

In preventive maintenance, equipment is repaired and serviced before failures occur. The frequency of maintenance activities is pre-determined by schedules. Preventive maintenance aims to eliminate unnecessary inspection and maintenance tasks, to implement additional maintenance tasks when and where needed and to focus efforts on the most critical items. The higher the failure consequences, the greater the level of preventive maintenance that is justified. This ultimately implies a trade-off between the cost of performing preventive maintenance and the cost to run the equipment to failure (Brereton, 2011, pp. 206-208).

Inspection assumes a crucial role in preventive maintenance strategies. Components are essentially inspected for corrosion and other damage at planned intervals, in order to identify corrective action before ...
