This paper present proposal of calculating building repairs and modernizations realization ratio. Presented ratio could be a point of reference at planning repair work sequence for a building or for comparing building values. This is a simple and objective method for estimate if the building is managed correctly, or not.
Analyses of building malfunctions and disasters have been carried out in many countries for a number of years. They are effected through continuous observation (monitoring), specialist technical and economic analyses, and papers published in various journals and presented at technical scientific symposia and conferences at home and abroad. The conclusions obtained from this work are used to make improvements in the programming, design, construction, use, insurance and valuation of buildings and structures.
The paper presents the results of research concerning building impacts, i.e. preventive maintenance conducted by mining companies and renovation work, on the durability of the traditional building development in the Legnica-Głogów Copper District. The basis for the research was an established database containing information about damage, wear and potential causes of damage and anomalies in 930 residential buildings, a typical town, suburban and rural development within the region the traditional masonry structure and 370 farm buildings, mainly barns, stables, and cowsheds. In the research a quantitative analysis was made of the effects of building impacts on the durability of the LGOM building development. An methodology was applied, which involved a comparative analysis of durability estimated on ground time trends of the technical wear of selected groups of buildings. For example, the influence renovation works on the durability was evaluated on the basis of comparative analysis of the progression over time of technical wear of buildings with preventive maintenance. The analysis for the investigated group of renovated buildings showed a relative 12.6% increase in the average durability in comparison with the not renovated buildings. This means that after fifty years of utilization the absolute difference in the average wear would be 4.9%
