This paper presents an analysis of selected criteria for choosing the most suitable contractor in a public
procurement process, and for appointing the contractor whose tender best meets the criteria used in Poland, Germany, United Kingdom and France. The national procurement regulations are based on the European directive 2004/18/EC that allows for an objective multi-criteria assessment of a tender offer. As foreign examples prove, the procedures used in the process of tenders’ evaluation, followed by a selection of the best bidder, vary, depending on the country of their application. Moreover, they show that the lowest price is not the most appropriate choice for the contracting authorities, if they adhere to the rule ‘value for money’.

https://doi.org/10.4467/2353737XCT.14.199.3287In modern construction there appear two parallel independent trends. On the one hand, large emphasis is put on raising durability of construction works implemented through the selection of appropriate materials with parameters tailored to the specific conditions occurring during the operation of the building. On the other hand, great importance is attributed to the problem of energy-efficient building design, which is reflected in the increasingly stringent records of existing legislation. In this paper some questions were raised concerning the both issues. The article presents the results of autoclaved aerated concrete studies, in particular, the deterioration of its strength and thermal conductivity due to moistness.
