Kostenplanung im Prozess der Instandhaltung von Bürogebäuden in großen Unternehmen

Abstract

As a management task with a high grade of autonomy, companies' maintenance is an es-sential element to secure core processes. Within its strategic characteristic many supporting duties and responsibilities are providing a dominant influence on core process availability and their economic efficiency causing high budget costs. This work conduces new scien-tific findings about the maintenances economic efficiency of technical real estate facilities in administrative buildings. Within the methodology the difficult time- and cost-structure as main object with the independent issues attendance, inspection, reconditioning and weak-point analysis is given. The research question is: Is it possible to develop the specific time-and cost structure to the maintenance of a reliable planning of Technical Building Equipment reliable planning of maintenance costs on the basis of appropriate explanans-rate models are developed? The problem is the structure of the cost structures of maintenance is much developed, then that plan different approach, models are used, the major influence on the financial planning of the maintenance of the company and have no reliability. The handling and solving the problem of science concepts follow a methodology in terms of content enclosed by being invested in a chain of determinants, partial results and starting points for the following analysis stage:  source and effect sizes of the maintenance costs  analytical data base maintenance costs  field approach to modelling maintenance costs  modelling approaches of plan maintenance costs. Therefore consolidated findings how far too little maintenance causes damage or if higher budgets function cost-saving and/or value enhancing were not provided. Helpful for the handling of the research question is the high praxis level in technical real estate facilities maintenance, the mathematic-statistical theory-potential and the analysis of important cost groups in maintenance. Methodically the investigation ranges over administrative buildings which data was accessible, especially the concerns Volkswagen AG and Vattenfall Europe AG (Germany). Abstract VIII The findings shows, that the economic efficiency of maintenance can be accrued and de-veloped in entity with known economic factors and quantitative Methods of economic analysis. With the alliance of economy, maintenance of equipment and econometrics we can find an advantage to connect the cost analysis of maintenance processes with calculat-able models, which allow an applycably cost planning. Therewith a better handling in the management process is given because a higher security in maintenance-planning and a sufficiently accurate control of maintenance-costs can be generated.
