An environmental impact on the condition of an unfinished building in the OWT technology

Abstract

Abstract. The aim of the paper is to present the state of the building erected in the OWT technology. The construction of the building has not been completed due to the financial problems of the late 90's of the XX century. As a result of the long-term environmental impact, the object was degraded due to the lack of a flat roof and windows. The impact of precipitation, wind and biological corrosion led to significant degradation and deterioration of structural elements and joints. The paper will present examples of damage caused by environmental impacts. Examples of damage of wall and floor elements as well the deeply corroded steel plate joints will be presented. Highly grown lichens, mosses or mold will be also presented as the examples of biological interactions onto the surface of constructional elements. Structural elements have been tested in a nondestructive manner using sclerometer tests. The results will be described and the conclusions will be presented. The analyzed object presents in an interesting manner that environmental influences could destructively affect the construction of precast RC structural elements, which constitute a significant percentage of the Polish construction market.

Diagnostics of Large-Panel Buildings—An Attempt to Reduce the Number of Destructive Tests

“…As presented in [27][28][29], large-panel buildings are characterised by numerous errors arising during production and installation, as well as degradation resulting from use often extending over 50 years. A number of papers can be found in the literature in which studies of large-panel buildings are presented [30][31][32][33][34]. Despite the development of non-destructive testing apparatus and its increased availability, there are still doubts about the effectiveness and validity of its use in practice.…”

Degradation Analyses of Systemic Large-Panel Buildings Using Comparative Testing during Demolition

“…On the structural side, there is one available publication on the case of demolition of a large-panel building that was damaged due to underground mining [ 32 ]. Buildings remaining in an unfinished state have also been a testing ground, with a smaller scope of research [ 33 , 34 ]. An interesting study was conducted on buildings after the 2019 earthquake in Albania [ 35 ].…”
