Summary: The current development level of civil engineering technologyenables the application of a larger number of alternativetechnological construction systems, differing from one another inthe construction materials of the structures, the methods ofmanufacturing the structural memebers, the sizesof those members,the places where the technological operations are carried out,the degree of technological equipment of workand theparticipation of living man's labour in the construction processin contrast to the work done by machines. Different construction technologies are in quiestion, withdifferent cost relations of the necessary single factors ofproduction ( work, object of work and means of work ) perphysical unit of measure of built structure, which signifies thatthe total costs of the factors of production are different.Consequently the conclusion may be drawn that constructiontechnology has an influence on constructions costs, that is onthe economic, efficiency of construction. That leads to thequestion of the choice of optimal technologz among the existingalternative ones. Because of the aforesaid, it is necessary to examine and analysethe influence of construction technology on the economicefficiency of building construction. All the factors influencingthe economic efficiency of building construction and having any,either direct or indirect, connection with constructiontechnology should be included in the analysis. Such a completeanalysiswill result in the development of a METHOD FOR EVALUATINGalternative construction technologies, based on the economicefficiency optimum standard, with a view to choosing thetechnology that enables construction with the lowest total costs,taking into accont the required quality of the structures. Theobtained method will be theoretically well-formed and applicablein practice.

Keywords: Technology/ Economic efficiency/ Analysis/ Method/ Evaluation ( assessment )

Research goals: It is a question of evaluating construction technologies, with a view to choosing the optimal one. So far a certain level of knowlege has been achieved about it. The problem of choosing the optimal technology among the existing ones is always present with all those that ara concerned with construction technologies. The current researches on it have produced more or less partial results, depending on the criteria on the basis of wich the evaluation has been done. In other words, the problem is in defining the criteria for evaluating the technologies. There is a relatively large number of criteria on the basis of which technologies can be evaluated so that technology chosen by one criterion does not usually meet the other criteria. A special problem arieses when the economic efficiency optimum standard
