The current public procurement law (Law No. 4734) was established in Turkey in 2003. The current law has fundamental differences from the previous one, Law No. 2886, in that the current law's main objective is to increase the effective use of public resources. Although the current law was enacted nine years ago, no in-depth research has been undertaken related to the extent of public savings. Thus, the aim of this research is to analyze the performance of public investments for construction with respect to their success in achieving on time and within budget completion. Additionally, a comparison between the completion duration and budget of construction projects undertaken under the current and the previous law is presented. To achieve these goals, historical contract documents addressing 878 and 575 public construction projects undertaken under two laws, respectively, were analyzed. In this context, the data mining method, including decision trees, artificial neural network, and support vector machines, was applied to predict the duration and cost deviations of the construction projects during the tender process, and the results were compared. It was demonstrated that the current law has contributed substantially towards the completion of the projects within estimated or envisaged durations and costs. The findings of this research can be generalized to countries with similar economical and organizational structures with Turkey.

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.

Prefabricated Building

The adoption of prefabricated building systems has grown due to the need to reduce duration and cost of construction projects, as well as to improve quality and working conditions. However, the adoption of those systems requires an intense exchange of information to integrate the production of components, logistics operations, and site assembly. This is particularly important in engineer-to-order environments, in which the level of uncertainty tends to be high. This research proposes a model for planning and controlling the delivery and assembly of ETO prefabricated building systems, emphasizing the integration between site installation and logistics operations. This model was devised in an empirical study carried out in a company that delivers and assembles prefabricated concrete structures. The main theoretical contribution is a set of approaches to implement the “pull production” and “reduce variability” principles in this particular context, exploring synergies that exist between Lean Production principles and Building Information Modeling (BIM) functionalities.

Cost Of Construction

Productivity is important in construction. Construction productivity is a significant part of production for construction projects. In the construction industry, many external and internal factors are never constant and difficult to predict. This factor leads to a constant change in productivity. It is necessary to make sure that the reduction of construction productivity does not affect the plan and work schedule and does not cause delays. The consequences of these delays can lead to serious loss of money. In addition, significant costs can be saved if productivity is improved, as the same work can be done with less labor, thereby reducing the total cost of construction.

Cost Of Construction

The study is devoted to substantiating the need to develop a cost controlling system in order to improve the efficiency of investors, developers, customers, general contractors, as well as representatives of the banking system who are directly involved in the implementation of investment and construction projects. The paper summarizes the innovations of the Ministry of Construction, Housing and Utilities of the Russian Federation in the field of determining the cost of construction at the stages of the life cycle of an investment and construction project, and suggests their adaptation to the activities of commercial customers. The factors of the rise in the cost of construction in the modern conditions of the investment and construction sphere are systematized, including topical issues of the rise in cost due to the increase in prices of building materials. The main risks arising from the implementation of the project associated with an increase in cost are highlighted. As the results of the study, stages of construction cost control with a description of their content and a system of cost controlling of an investment and construction project are proposed.
