On Use of Construction Technology Designs for Expert Opinions

This article describes the basic principles and results of an expert system for construction planning and management. In the field of expert opinions, the system greatly helps to determine the limit of unreasonably low construction prices on the basis of a rapid cost analysis. Additionally, it can determine the technologically shortest possible construction periods or can answer the question of whether it is possible to complete the construction in the specified period, provided that a certain amount of construction is currently underway, which is very useful in expert opinions. The system is based on modeling the construction process using the so-called construction technology network graphs. This method allows, among other things, to create and use so-called typical network graphs as preprepared models of individual types of objects in the form of computer files, which can be modified according to the spatial structure of real buildings or facilities when used in creating a feasibility study or efficient time and financial planning and management of the building process. The system also enables the automatic creation of quality assurance checklists (inspection and acceptance plans for quality assurance), environmental plans (plans for the elimination of adverse effects of construction activities on the environment), and safety and health plans. Direct links to the bills of quantities (list of works and supplies with numbering of individual items), budgets (list of works and supplies with prices), or production calculations, despite the operational records of the actual construction process also on the company's accounting agenda, are available.
