A Novel Hierarchical Technique for Range Segmentation of Large Building Exteriors

The article presents the concept of monitoring buildings and infrastructure elements located near large construction investments (the construction of high-rise buildings of the Oak Terraces housing estate in Katowice and the construction of a tunnel under the roundabout in Katowice along the intercity express road DTŚ). The impacts include deep excavation, lowering of the groundwater level over a large area, and dynamic influences related to the use of impact methods of soil improvement. The presented monitoring includes observation of the groundwater level with the use of piezometers, geodetic measurements of settlement and inclinations, as well as the measurement of vibration amplitudes generated during the works involving shocks and vibrations. It was also important to observe the development of cracks on the basis of a previously made inventory of damage. The results of the monitoring allow corrections to be made in the technology of works (e.g., reduction of vibration amplitudes, application of additional protections at excavations, etc.) or the use additional safety measures. Currently, there are also monitoring systems used during the operation of completed facilities.

Do So

This paper contributes to the circular economy (CE) literature by investigating the drivers of success of the CE implementation in the construction sector and how those drivers can complement any implementation process in small and medium enterprises (SMEs). To do so, we analyzed the case of TECMO Estructuras Metálicas, using the methodology proposed by Jaca and colleagues to implement the CE in SMEs. It is a Colombian company with more than five decades of experience in the manufacture and installation of steel and aluminum structures for small and large building and infrastructure projects. The data were collected between August 2019 and November 2020 through direct communication with the company via workshops, meetings, and company reports. This research found that five drivers are relevant for implementing CE in the construction sector: fertile ecosystem, management commitment, identification of valuable materials, green teams, and CE intermediaries. Moreover, this study also contributes to teaching the implementation of the CE in companies, since it shows that through the methodology presented, implementation projects can be developed in postgraduate classes.

Large Building

The objectives of this paper are to review measurements of airtightness of 2 large building groups – middle size shops, and warehouses/distribution centres. The mean air leakage rate at 50 Pa pressure difference q50 was 1.04 m3/m2h and 1.35 m3/m2h for shops and warehouses respectively. Analysis of measurement results is valuable because it allows to make a conclusion about compliance of national and corporative construction airtightness norms with actual air barrier condition on a comissioning stage. In the concluding part of the study there are suggested ways to improve air barrier such as review of construction norms, implementation of a mandatory testing and quality control of a measurement.
