Centralized System

In order to improve construction site management, we make the architect’ position as the starting point for our research ,analyze the similarities and differences between the project manager and the architect and transform the traditional building construction management system from centralized system into flat -like system. Furthermore, we propose that the implementation of the system must be assisted with the construction of credit system and the establishment and implementation of personal practice insurance system.

Unsafe Condition

Construction sites records high accident and incident rate due to lack of safety measures. Safety assessment rating is significant for every construction site to know safety status of the particular site. In this research TR safety observation method is used to assess the site performance. As unsafe condition is the key factor in every construction site, this research considers the possible unsafe conditions to assess the site performance. A questionnaire survey is done with the workers to know the existing safe conditions. Results showed that the safety performance of the site is 39%. Then every unsafe condition is ranked with respect to severity rating for detailed analysis. Furthermore bowtie analysis is used to identify the causes and consequences of the unsafe conditions. Through this analysis the owner can reduce the risk of every event and improve the site performance.

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.

Traditional and innovative ways of constructing temporary roads at a construction site are considered. The basic principles of the preparation of construction operations are given, which should be taken into account at this stage. Particular attention is paid to the preparation of the construction of the facility and preparation for the construction and installation works. The organization of designing construction roads, temporary and permanent, is considered. Methods for determining the parameters of construction roads are described. The main technical indicators of construction roads are given. Dangerous areas of the roads are indicated. The main purpose of the research is to generalize and systematize the modern ways of arrangement and operation of auto-roads on a construction site. For carrying out of the study the methodical and scientific literature on the subject was analyzed, and also the statistic methods of data investigation were used. The main results of the research is the accomplishment of estimation of expenses on arrangement of auto-roads, the indication of order of working out of design of the auto-roads, also the indication of necessity of use of permanent roads as temporary. The design of temporary and permanent construction roads is very important because of their greater use in comparison with railway transport and a great influence on the supply of construction materials.

Weather Changes

Research from the International Energy Agency about indoor ambiences and nearly zero energy buildings (nZEB) in the past has been centred on different aspects such as the prediction of indoor conditions as a function of the weather using laboratory material properties for simulations and real sampled data for validation. Thus, it is possible to use real data for defining behavioural groups of indoor ambiences as a function of real vapour permeability of internal coverings. However, this method is not suitable for modelling it and predicting its behaviour under weather changes, which is of interest to improve the method of selection and use of building construction materials. In this research, artificial intelligence procedures were employed as the first model of permeable coverings material behaviour to provide a newer understanding of building materials and applications for the generation of new control procedures between the mechanical and electronic point of view of building construction materials.
