The wide and scientifically grounded use of gabion structures was restrained due to the lack of regulatory and methodological foundations and documents for the design and construction of these structures in road and bridge construction, in which technical requirements, design solutions, conditions and scope of gabion were worked out, systematized and formulated designs.It is very important to have a high-quality methodological and regulatory framework necessary to regulate the use of gabion structures, develop new, improve and expand the current standard solutions for strengthening the slopes of the subgrade, drainage devices and other structures, as well as in order to improve the quality of individual design of road and bridge structures using gabion structures, scientific, methodological and expert support of this design. So, the purpose of the work is to analyze domestic and international experience in the use of gabion structures in the construction industry in order to study calculation methods and technology for the construction of gabion structures. The object of research is gabion structures.The paper studies the theoretical and technological aspects of the use of gabion structures in road construction.The domestic and world experience of using gabion structures in the construction industry is analyzed. The advantages of using gabion structures in the development of design and construction solutions for the device and strengthening are considered.Methods for calculating gabion structures and their analysis are investigated. Due to this, the possibility of calculating gabion retaining walls with a height of more than 8 m was presented. Based on the calculation method, it was concluded that the use of gabion retaining walls of such a height requires lower costs than the devices of concrete and reinforced concrete retaining walls.

A meta-synthesis approach was used to identify, synthesize, and categorize appropriately factors in the literature that contribute to design documentation quality. The categories include factors on quality attributes, quality indicators, and quality-influencing factors. Findings indicate that the quality of design documentation in practice is unsatisfactory, therefore, there is a need for collaboration between the owner, designers, and end-users to improve design documentation quality. The results offer pragmatic data on design documentation quality in the construction industry between the years 1992 and 2019. However, further research on the significant impacts of poor-quality design documentation on construction projects is recommended.

In this article we carry out the analysis of the possible directions and consequences of transformations of the existing models for implementation of investment-construction projects in relation with integration of information technologies and the construction industry in modern Russia. Such integration is considered as the most useful tool to solve such chronicle problems of the construction industry as low quality of works, missed deadlines and sustaining the best ratio “price-quality” for the customer. The basis for such integration is the technologies of informational modeling of construction objects. We investigated two basic models: disintegrated purchases and integrated purchases whose transformation will be directed towards development of mechanisms of partnership between participants of investment-construction projects, expanded use of “integrated” contracts in the system of state purchases of construction works and further centralization of control in the system of construction for state purposes.

Quality of communication is a key factor in the success of construction projects. Visualization technologies can play an important role in improving the quality of data by improving human comprehension and increasing the depth of the information delivered. Visualization has for some time been identified as one of the major technology themes allowing development of construction processes. However, visualization has not been embraced as a strategic tool by construction companies, and they generally fail to take full advantage of available visualization tools. This paper aims to evaluate the extent of visualization as a communication tool in the construction industry and to determine potential benefits to be gained through implementation of visualization. The current state of the use of visualization for communication in Turkish architecture, engineering, and construction companies is mapped through surveys and interviews. Information flow contents and types are analysed to determine the types of information in the construction process that may benefit from visual representation. According to the priorities of the expectations ranked by the users and the potential of different visualization tools, the level of visualization required for each data flow is determined by a quality function deployment (QFD) based approach.Key words: visualization, construction, visual communication, quality.

Delay in payment to contactors and other relevant parties have caused serious problem on the successful execution of construction projects in the country. It causes several problems to the contractor and other participants. The aim of this study is to determine the causes of delayed payments in the construction industry. The objective of this study is to identify the causes of delayed payment. In order to obtain valid data for the study, questionnaires were designed and distributed to a randomly selected sample of one hundred individuals among contractors, subcontractors, consultant and clients in the Nigerian construction industry. In total, eighty five completed questionnaires were returned and then analysed statistically. The total mean score was used to determine the ranking of the results of the study. Client’s disagreeing on the valuation of work done, slow processing of variation orders and poor quality of works were the major causes of delayed payment identified in the study. It was recommended that the stakeholders should work as a team in the execution of project to avoid bottlenecks usually encountered in agreeing contractors‟ payment. In conclusion, if the necessary action can be enforced, the problem of delayed payment can be reduced drastically.

PurposeDue to the fragmented and complex nature of the construction industry, many countries, including Singapore, have progressively encouraged greater collaboration amongst major stakeholders in the industry. It is hoped that doing so will result in an increase in the quality of construction projects. Given the long duration of typical construction projects, it is plausible for collaborating parties to develop close and personal relationships. In recent years, corruption cases arising from familiar collaboration have caught the public's attention. This study seeks to better understand familiar collaboration and its adverse impacts on the quality of construction projects.Design/methodology/approachA mixed research method was adopted, with a questionnaire survey distributed to 32 respondents representing client and contractors. This was followed by interviews to validate the survey findings.FindingsThe findings suggest that, when there is a lack of surveillance, familiar collaboration is likely to lead to favouritism and dishonesty, which can have an adverse impact on the quality of construction projects. The findings additionally suggest that value for money, conformance to specifications and fitness for purpose are the main aspects of quality that are likely to be adversely affected by corrupt practices bought about by familiar collaboration.Originality/valueIn this paper, these relationships are described using the term familiar collaboration. Strong and intimate relationships of this type may lead to a danger of parties committing corrupt practices. This study is one of the very attempts seek to better understand familiar collaboration and its adverse impacts on the quality of construction projects.

One of the problems that can arise in the way of successful implementation of construction projects is the separation and inadequate interaction between the participants in the process in the design and construction of the facility. This problem can adversely affect the results of the project, the quality of its implementation, implementation time and cost. Often in the implementation there is a problem of providing all parties of the design and construction process with access to information and communication tools. The article discusses the possibilities of joint activity in the design process using cloud computing. In particular, the introduction and development of concepts for innovative interaction tools, such as context-sensitive cloud computing information systems (CACCIS), is being considered to facilitate the design and construction processes using new technological capabilities.

A large number of stakeholders in construction projects makes the construction industry prone to disputes. The historical separation between design and construction add to this phenomenon by having a consultant for design and a contractor for construction. Communication breakdown, frequently, is the first sign of problems, notably in the relationship between the Contractor and the Consultant. Therefore, it appears that the split between design and construction has given rise to two separate cultures in the construction industry. This paper attempts to identify whether there is a difference in organisational culture between Consultants and Contractors taken as two groups and determine whether a specific attribute was related to the cultural differences between the two entities. Based on case studies it was found that consultants are biased towards Clan culture while contractors are biased towards Market culture. However, both groups show similar affinity to Adhocracy and Hierarchy cultures.
