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.

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.

The purpose of the present study is to grasp the situation of construction sites easily by distinguishing the movements of construction workers at construction sites from the accelerometer data attached to their waists. For the construction manager to accurately perceive the active or inactive state of his workers, their movements were classified into three distinct categories: walking, standing, and sitting. We tracked and observed two rebar workers for 5 days at a large building construction site. Their movements were classified by two-axis plots of (1) the difference between the maximum and minimum absolute values and (2) the value of acceleration at each second, and visualized by a heatmap among others for this trial. The results showed that despite the difficulty in distinguishing rebar work without a total body movement while sitting, the accuracy of discrimination was 60–80% in walking and sitting. From this analysis, we were able to identify repetitive tasks and the differences between morning and afternoon tasks. Furthermore, by applying simple visualization, we could concisely represent changes in work intensity over a relatively long period.

In fluid numerical simulation calculation, FLUENT is one of the most commonly used engineering software. By the way of pressure velocity coupling, FLUENT can solve the flow field, and use the finite volume method to speed up the convergence. In order to improve the calculation accuracy, FLUENT is divided into single precision and double precision to meet the need of practical engineering. In this paper, by using FLUENT numerical simulation software, combined with UDF programming, we analyze the temperature and smoke distribution when large building fire occurs. The GAMBIT software is used for the numerical modeling, and we use Tecplot software to carry out the post processing of results. Through numerical simulation, the fire temperature value reaches 1050K without wind, while with wind the temperature is 1030K, , which is consistent with the actual situation. In the absence of ventilation condition, concentration is 0.0112; under the condition of ventilation concentration is 0.0052, which is consistent with the actual situation. Therefore in the building fire safety, the first thing to consider is ventilation, which can reduce the fire temperature and concentration and security personnel safe evacuation.
