Społeczno-gospodarcze trendy rozwojowe, wymagają aby gospodarka oparta była na zrównoważonej konsumpcji oraz zrównoważonych wzorcach produkcyjnych, poprzez prowadzenie efektywnej gospodarki recyrkulacyjnej – również w wymiarze środowiskowym. Dlatego też, projektowanie procesów gospodarczych przyjmuje coraz to bardziej złożony charakter. Artykuł prezentuje metodę i wyniki oceny środowiskowej wybranych etapów procesu recyklingu betonu. Rezultaty posłużą do dalszej – holistycznej oceny wariantów gospodarowania odpadami betonowymi na budowie.

Owing to the numerous advantages of this technology, the continuous development of monolithic constructions have been made possible. The complexity of structures using this technology have been made possible thanks to the use of modern shuttering, the production of high quality concrete mixes carried out by professional concrete-mixing plants and efficient logistics supporting investment projects. The weakest element in organisation of these works is the supply of reinforcing steel, an expensive resource which is consumed in large quantities thus requiring extensive logistical planning. On the basis of their professional experience, the authors of this paper present their analysis of logistical models for supplying construction sites with reinforcing steel. Using the AHP method, they carry out a multi criteria evaluation of possible supply systems. Then, applying decision inventory theory models, they determine control quantities leading to logistic system optimisation according to the selected criteria.

Presented topic concerns the location on the crown of the high slope settings crane to be mounted on the roof structure construction of the building NOSPR in Katowice. Set AC500 crane mounting on a high slope required to verify the safety of the location, the forecast behavior of the slope during the operation of the crane, and conduct constant monitoring of geodetic displacement of the slope. The aim of the paper is to present the proposed and implemented methodology based on data acquisition geotechnical soil slope using the methods of surveying as well as analysis of integrated measurements for the design and implementation of the safe conduct of works chosen method of installation.
