Abstract:The aim of this paper was to present those factors which have a bearing on the accident rate in the construction industry. The main problems afflicting this industry, i.e. the exceptionally high accident rate, the unidentified causes of accidents and the poor reliability of the available data, are highlighted. It has been established that it is difficult to optimally and consciously counteract accidents. In order to attempt to compile a survey, available literature on the causes of accidents in this industry was carried out to compile a coherent and comprehensive list of accident factors dispersed in different publications. The results are presented in a tabular form and serve as an information base for persons interested in identifying the causes of accidents in order to eliminate them, and are the starting point for further research in this field. Moreover, the author concludes that knowledge of the influence of the particular causes on the genesis of accidents is also essential in order to undertake optimal measures at all the stages of safety management.
Abstract:Presented topic concerns the location on the crown of the high slope settings crane to be mounted on the roof structure construction of the building NOSPR in Katowice. Set AC500 crane mounting on a high slope required to verify the safety of the location, the forecast behavior of the slope during the operation of the crane, and conduct constant monitoring of geodetic displacement of the slope. The aim of the paper is to present the proposed and implemented methodology based on data acquisition geotechnical soil slope using the methods of surveying as well as analysis of integrated measurements for the design and implementation of the safe conduct of works chosen method of installation.
Abstract:When organising work at height, the site manager has a duty to provide adequate security measures which will ensure safe working conditions. The correct criteria adopted to ensure the safe movement of equipment and materials and the safe implementation of all professional activities by all employees. This paper attempts to identify and describe systems set up to protect against falls from height, without the use of scaffolding, employed in today’s construction market.
Abstract:The construction industry is characterized by a high level of hazards to the life and health of employees and by a high accident rate. Knowledge relating to the course of the accident process plays a major role in work safety assessment and in accident prevention. On the basis of GUS reports and the EUROSTAT accident model a comprehensive general model of accident situation development has been developed. The model enables one to trace the different possible configurations of the events occurring in accident processes in the construction industry and to determine the most probable scenario of events. It is essential to define such scenarios in order to correctly specify the directions of preventive measures.
Abstract:This paper presents the process of the development of methodologies for assessing the state of safety on construction sites. An analysis was conducted to calculate the number and causes of accidents in the construction sector over the last few years, and the main groups of factors affecting the state of occupation safety have also been defined.
Abstract:The complexity and need for a comprehensive approach to construction projects programming helps in researching the different methods of the risk estimation for construction projects. The risk estimation, carried out at the planning stage, not only enables rational investment but also the rational project management during construction. The paper concentrates on the possibility of applying the multi-criteria analysis for the selection of construction projects taking the risks into account.
Abstract:Construction works need to be implemented in accordance with design documentation, technical and performance specifications as well as being carried out safely, on time and within budget. There are however various events, which can occur during the process of implementation, some as a consequence of the natural environment, others occupational, which can either disrupt the execution of and/or have a negative effect on the result of works. In such situations, the duration of works may be prolonged and thus the costs of a particular task may increase beyond the planned budget. A series of such events may lead to the final deadline and the total cost of works completion being greater than that which had been fixed in the contract. However, assuming the parameters of the PERT-beta probability distribution and three-point estimation method, it is possible to estimate and thus plan for two kinds of risks to works. The first is the risk to the deadline of works, and the second is the risk to the cost of works. Changes in risks are presented using charts of risks. These charts describe possible changes in the interval of risks [0, 1] depending on a series of increasing values of deadlines and costs affecting works completion.
Abstract:The paper contains a specification of the notions of risk, transport infrastructure and crisis situation. The study also presents selected methods of identification of risks to transport infrastructure facilities, based on the example of a bridge facility.
Abstract:This paper presents a number of factors which influence the design and construction of a geotechnical structure, i.e. a road tunnel. For this type of structure, it is necessary to thoroughly examine the geological conditions and the properties of the rock mass. Research carried out on the basis of drilling gives only local results, which consequently only provides an estimated description of the characteristics and properties of the rock mass.
Abstract:To rationally prevent defects, you must first have knowledge of the defects, their causes and the associated costs. A key objective of the research presented is to attempt to demonstrate the application of various methods used in production engineering, in the context of today’s economy requirements and transfer knowledge gained from previously completed projects, with the aim of increasing the quality multifamily housing. A study of faults and subcontractors was carried out for the period 2006/2013. Eight construction projects with a total usable area of approximately 117,000.0 square meters and 1,524 apartments were studied. This is one of the first studies, for this period, carried out based on multifamily building projects in Poland.
