The Quality and Reliability in the Structural Design, Production, Execution and Maintenance of the Precast Residential Buildings in Poland in the Past and Now

Abstract

The article is a review of solutions, errors and mistakes in the project design and execution and their impact on reliability and durability of structures. Were used the results of inspections of 95 precast residential buildings situated in Warsaw, build in years 1961-1994. Inspections were made in years 2005-2006 and 2014. The summary of author researches [1,2,3,4] shows that the precast concrete prefabricated buildings can achieve real duration of use not less than 100 years. Taking into account quite good maintenance, intensive modernization and greater economic value of the housing stock in Warsaw can be assumed that their service lives may reach 120-150 years.

Risks of the Durability of Large-Panel Buildings Elevations in Reference to the Conclusions from Technical Conditions Audits

“…Previous authors studies [1,[8][9][10][11]] and the wide current work allow concluding that it is possible long-term safe use of prefabricated large-panel buildings. Durability of buildings properly exploited, who are under constant supervision is estimated as comparable to buildings made of monolithic technology.…”

The Determination of Priority Areas for the Construction of Green Roofs with Use of the Urban Area Valorisation Method

“…Also roof load capacity analysis of buildings was performed. [75][76][77][78]. For the buildings under study, the analysis was performed based on: the technical data contained in the literature on the structural system [79,80]; technical documentation for a typical building; the snow load standard valid in the period of building erection [81] and the current standard adapted to the European norms [82].…”

Application of It Tools in Managing Small and Medium-Sized Enterprises in the Context of Creating Entrepreneurial Orientation

“…Terminy te powinny wynikać z zasady najmniejszego nakładu środków na osiągnięcie celu, jakim jest utrzymanie stanu technicznego budynku na odpowiednim poziomie (Runkiewicz, 2010). Wcześniejszy remont ulepszający stan techniczny budynku prowadzi do zmniejszenia zniszczeń, co powoduje zmniejszenie sumarycznych nakładów (Knyziak, 2016;Radziszewska-Zielina i Śladowski, 2017). Często jednak często z powodu oszczędności środków decyzje dotyczące prac naprawczych są przesuwane na dalsze lata użytkowania obiektu.…”
