Raising the efficiency of the building lifetime with special emphasis on maintenance

The problems of creating buildings with efficient lifetime has been analysed with special emphasis on their maintenance. First, the principles of a complex analysis, functional considerations, cost‐benefit ratio optimization, interrelation of sciences, mathematical simulation, etc., had been analysed which enabled the authors to work out various systems of decision making. In this paper, one of these systems ‐ “housing refurbishment decision making”, is described at length. Also, a number of ways of achieving more efficient lifetime of a building, with special emphasis on its maintenance, are presented.

Future cooperation trends in the building industry

Advanced forms of cooperation concepts have begun surfacing in the construction industry, inspired by cooperation between companies in other industries. The purpose is often of strategic character and these cooperation forms are hence long-term. These cooperation concepts are striving for continuous improvements in regard of both delivering more value to the client and removing waste in the supply chain. The experiences so far reveal that cost reduction up to 50% and reduction of lead time up to 80% is possible. This could set new standards for the construction industry and raise productivity.
