EFFECT OF RISK ON ECONOMIC EFFICIENCY OF OVERCLADDING SYSTEM

When a decision is taken about assembling an overcladding system on building external walls, an expected profit is calculated according to the economic discounting formulae. However, these formulae do not take into account the unplanned repair costs. The unplanned repairs have to be done to remove the defects which appear on a building wall overcladding during its service life. In order to do that the authors have performed the experts surveys of technical condi- tion of the existing overcladdings. These overcladdings were assembled on the external walls of 497 apartment buildings located in Wroclaw (Poland) in 1990÷2000. The qualitative results of technical condition experts surveys, their transfor- mation into the quantitative values done according to the elaborated model and estimation of the risk related to the ex- pected profit decrease are presented in the article.

Technical and economic aspects of revitalization of down-town tenement-houses in Wrocław

AbstractIn the paper the authors examined the relations between the physical deterioration degree and the price of the tenement-houses in Wroclaw. The researches concern the years 1991–2009. According to the following analyses: technical, technical-economic (concerning the relations between buildings technical condition and buildings price) and economic the authors have come the conclusions concerning the sensibility of the revitalization work. The authors also estimated the purchase limit profitability of the tenement-houses, which are going to be repaired and modernized or to be demolished and next to be built a new tenement-house. The direction of the engineering activities was shown. They could improve the economic effectiveness of the revitalized tenement-houses.

Selected aspects of construction projects selection including risk estimation

The complexity and need for a comprehensive approach to construction projects programming helps in researching the different methods of the risk estimation for construction projects. The risk estimation, carried out at the planning stage, not only enables rational investment but also the rational project management during construction. The paper concentrates on the possibility of applying the multi-criteria analysis for the selection of construction projects taking the risks into account.
