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.

Identifying the effects of low bid award system in construction projects can be used as benchmark to find alternative method to low bid award system in the future of construction industry. The results of questioner survey conducted to determine the effects of awarding lowest bid award system in construction projects of Ethiopian southern nation are presented in this study. Personnel from consultants, owners and contractors are among the survey`s respondent. The result of the study outlines promote transparency, avoid fraud and corruption, promoting competition amongst contractors, excessive time overrun, compromise quality and hindering profitability of contractors as the top ranked effects of low bid award system. Construction industry participants have started recognizing that accepting the least price bid does not guarantee maximum value. Achieving a value-based procurement approach is a challenge, particularly for the Pakistani public sector clients, who are limited in their ability to evaluate the competitive bids based solely on the lowest-bid award system. Persisting problems of inferior quality of constructed facilities, high incidence of claims and litigation, and frequent cost and schedule overruns have become the main features of public construction works contracts. This research was undertaken to assess the performance of public owned construction projects awarded on a lowest bidder bid awarding system.

Construction Works

Reducing the duration of construction works requires additional organizational measures, such as selecting construction methods that assure a shorter realization time, engaging additional resources, working overtime, or allowing construction works to be performed simultaneously in the same working units. The simultaneous work of crews may affect the quality of works and the efficiency of construction processes. This article presents a simulation model aimed at assessing the impact of the overlap period on the extension of the working time of the crews and the reduction of a repetitive project’s duration in random conditions. The purpose of simulation studies is to provide construction managers with guidelines when deciding on the dates of starting the sequential technological process lines realized by specialized working crews, for sustainable scheduling and organization of construction projects.

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.

Construction Industry is evolving amid the fourth industrial revolution. Transportation, commerce, manufacturing and many other industries ripened the current technological advancement and are striving to utilise every development in the IT sector. The procurement of construction works is known to be very conventional and backward in the adoption of digitalisation. The construction industry's procurement and supply chain are blamed for the most inflated cost of construction projects, mainly attributed to a lack of transparency and trust between the industry stakeholders. This research explores the challenges of E-procurement adoption in the industry and identifies the potential opportunities for its usage. This investigation's data are acquired through interviews, and the data are analysed using qualitative content analysis. This study reveals compounding challenges (i.e., corruption and lack of commitment) that lead to the failure of such efforts in Nigeria and the potential prospects (i.e., transparency and efficiency). This study is essential in developing a more effective and transparent process of procurement so that the Nigerian construction industry is not be left behind in the fast-digitalising markets.

Appearance of new types of work requires workers, foremen and superintendents know how most effectively to manage the construction process, and often it is impossible without a qualitatively prepared the technological card on a certain type of work. Routing is an integral part of the design and technological documentation. It is necessary to modernize the process of formation of technological cards and create a new one, following the trends of development of the construction industry. Use of modern information technologies for the formation of technological cards will eliminate a number of personnel issues facing the construction complex. Raise the level of preparation of design and technological documentation will be possible due to introduction of methods, models, algorithms for automation of documentation. The process of development of technological cards in construction is one of the most difficult and complex and, at the same time, the least automated. Therefore, development of new models and methods of automation, change the very process of creating this section of organizational and technological documentation, will allow to solve an actual problem of improvement of quality of formation of technological cards, reduce time and cost of construction. Methodological and theoretical basis of research includes: the theory and practice of CAD, system analysis and construction or for system architect, database design, theory of algorithms, thematic work of the authors, the normative documentation in the field.

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.
