The paper presents the process of selection the foundation instalment alternative, which have to be the most appropriate and safe for building which stands on the aquiferous soil. The selection is based on a set of criteria: costs of instalment, instalment duration, the complexity of decisions, advantages and disadvantages of decisions, transferability and maintainability of installed foundation system, past experience implementing the approved decisions, etc. The criteria for evaluation and their importance are selected by taking into consideration the interests and goals of the client as well as factors that influence the efficiency of construction process and safety of future building. The solution of problem was made by applying Additive Ratio ASsessment (ARAS) method. The proposed technique could further be applied to substantiate the selection of effective alternative of structures, technologies, investments and etc.

Artykuł prezentuje proces wyboru alternatywnego usadowienia fundamentu najbardziej odpowiedniego i bezpiecznego dla budynku stojącego na gruncie wodonośnym. Wybór bazuje na zestawie kryteriów: koszt usadowienia, okres usadowienia, stopień skomplikowania decyzji, zalety i wady decyzji, możliwość przenoszenia i konserwacji usadowionego systemu fundamentu, doświadczenie z wdrożenie przyjętych decyzji, itd. Kryteria oceny i ich znaczenie są wybierane z uwzględnieniem interesów i celów klienta oraz czynników wpływających na efektywność procesu budowlanego i bezpieczeństwa budynku. Rozwiązania problemu dokonano przy zastosowaniu metody ARAS. Proponowana metoda może w przyszłości być zastosowana do uzasadnienia wyboru struktury, technologii, inwestycji itd.

Construction companies usually perform several construction projects at the same time. Projects differ by complexity, duration, budget, variety of works, and number of implementers. Also vary the results of the projects: some of them have been implemented successfully, other terminated with losses or accidents. To determine the causes of one or another result the analysis of project work flow indicators should be performed. The evaluation of project indicators during implementation is not easy task due to the lack of up to date data and indicators measuring problem. The purpose of the research was to analyze common project management problems, the success factors of construction projects and to illustrate how to assess a projects' execution efficiency by mean of the aggregated indicator in particular company. In case study the problem of project performance indicators selection was analyzed, the aggregated project's performance criterion was determined by applying the methods of multi-criteria analysis and logarithmic normalization method was applied. Results show that by using the aggregated indicators it is easy to compare the projects, the received impartial information is useful for strategic planning, quality management, for solving the tasks of resource allocation, motivational project evaluation.
