The purpose of the work progress and cost control systems in a construction company is to indicate, in real time, the deviations from their planned schedule and budget. In reality many construction companies do not employ effective control systems and do not receive the desired information about their time and cost performance.
The objective of the present research was to define the premises of an efficient and effective management information system and subsequently examine the performance of the operating control systems in light of these premises in a representative sample of construction companies. The sample was to include companies of various sizes so that the influence of the company size on its performance in this respect could be examined.
The survey which was conducted in light of the analysis of the desired control systems attributes encompassed 14 companies. Structured interviews were carried out with their chief executive officers and also with the engineers specifically responsible for the operation of the computerized control systems in each company.
The main conclusion of the survey was that in the small and medium size companies the objectives and the structure of the control systems were largely ill-defined and therefore the systems were not operating efficiently. On the other hand, the large companies effectively integrated the standard off the shelf software in control systems, tailored in accordance with their specific needs. These systems perform satisfactorily in light of their stated objectives. Another noteworthy result indicates the lack of integration of the schedule and cost control systems in all the surveyed companies. The prevailing opinion was, that the effort necessary for such integration would not be justified by the prospective benefits.
