The Impact

The digital transformation in the construction industry, which is also referred to as Construction 4.0, is gaining impact in recent years. BIM as the central point for model-based planning and communication is at the centre of this development. This paves the way for the implementation of further technologies, such as augmented reality (AR) or artificial intelligence (AI) in the construction process. However, the submission process currently receives little attention in the BIM project cycle, even though it has a significant impact on a building project. There is a huge potential for the application of BIM and AR in the building submission process. BIM allows partly automatic compliance checks to be performed. The BIM model and the results of these checks can be used as basis for the AR model. This paper investigates an application for AR in a BIM submission process. Here we show that especially the plan check process and hearings in the approval process can be improved and sped up by combining BIM and the visualization technology of AR. In this process, AR can support the building authority in checking the compliance with building regulations. Additionally, non-experts involved often have problems grasping the planned building project just based on the technical 2D plans. In this case, AR helps them to visualise the impact of the planned project and allows for better judgement. Use-cases are presented, showing strategies to improve the plan check process and assist the building authority as well as the persons involved, for both experts as well as non-experts. Finally, the requirements, technical implementations, and effects of an AR application for the plan check process are described. An AR-supported plan checking process can vastly improve the presentation of technical content. This leads to better understanding and more transparency for non-experts. Because AR is relatively easy to use, it might become ubiquitous not only to experts, but also to the general public.

Problem statement. The introduction of new requirements for rationing in the construction industry provides for changes in the rationing methodology, through the use of a predominantly parametric method. This stimulates the use in management of modern approaches, methods and mechanisms, technologies, innovative organizational and technological solutions to improve the quality and volume of construction, which in turn can accelerate the recovery from the crisis and the development of the construction industry as a whole.The use of the parametric method, in addition to the certain advantages indicated above, creates new challenges for the efficiency of management in the construction industry. On the one hand, there is an increase in the alternatives of possible managerial and organizational and technological solutions; identification of the list and consequences of risks for each alternative; improvement of the procedure and processes for predicting the consequences of each of the alternatives; putting forward new requirements for the information necessary for decision-making, the possibilities of its analysis and interpretation.On the other hand, the use of such a selection mechanism and the lack of clear requirements and orders can increase the costs of achieving the declared quality and reliability requirements of the construction object, and accordingly increase financial and organizational and technological risks. This creates the preconditions for the use of integrated management with the use of appropriate organizational and technological solutions that can satisfy both the requirements of quality management and risk management in construction. Purpose of the article − describe and substantiate the possibility of applying the mechanism for choosing organizational and technological solutions aimed at achieving parametric criteria as target indicators for managing construction processes in conditions of uncertainty using a functional model of a system-integrated approach. Conclusion. It has been substantiated that for an effective process of managing construction processes within an integrated approach, in conditions of uncertainty, it is necessary to use a system-wide algorithmic mechanism, which will ensure the coordination of control functions, their parallel and continuous execution within individual processes, the choice and decision-making in emergency situations for a minimum possible time period.This requires the compliance of each organizational and technological solution with the established criteria and the possibility of their comparison, in order to select the most effective in terms of leveling risk, achieving efficiency − in relation to their cost; and criteria for feasibility, assessment of the impact on quality indicators, implementation in time, competence and technological feasibility − in relation to their ability to implement. Keywords: construction process management; rationing; parametric method, integrated approach; processapproach; situational approach; a mechanism for choosing organizational and technological solutions

The Impact

Construction industry activities, from material extraction to the end of the structure life, affect the environment negatively. For a sustainable construction process, economically, environmentally, and socially friendly practices are essential, and reverse logistics is one solution that can provide such an approach. In reverse logistics, obsolete products are reused in a new production, while reducing negative effects to the environment. In this study, we assess the current state of research on reverse logistics practices in the construction industry. The study presents a comparative data mining analysis, followed by a content analysis. The results show that the construction industry literature ignores the impact of reverse logistics practices on upstream construction activities. We argue that industry practitioners must take reverse logistics decisions in the early phases of the construction process by considering both upstream and end-of-life construction activities, and we recommend a reverse logistics decision framework for successful reverse logistics implementation. The findings of this research are significant for decision-makers in the industry. We urge that sustainable practices be employed in the industry. Furthermore, a quantitative analysis is suggested to strengthen the arguments made in this article.

This paper proposes an augmented reality (AR) strategy in which a Lamb waves based impact detection methodology dynamically interacts with a head portable visualization device allowing the inspector to see the estimated impact position (with its uncertainty) and impact energy directly on the plate-like structure. The impact detection methodology uses a network of piezosensors bonded on the structure to be monitored and a signal processing algorithm (the Warped Frequency Transform) able to compensate for dispersion the acquired waveforms. The compensated waveforms yield to a robust estimation of Lamb waves difference in distance of propagation (DDOP), used to feed hyperbolic algorithms for impact location determination, and allow an estimation of the uncertainty of the impact positioning as well as of the impact energy. The outputs of the impact methodology are passed to a visualization technology that yielding their representation in Augmented Reality (AR) is meant to support the inspector during the on-field inspection/diagnosis as well as the maintenance operations. The inspector, in fact, can see interactively in real time the impact data directly on the surface of the structure. To validate the proposed approach, tests on an aluminum plate are presented. Results confirm the feasibility of the method and its exploitability in maintenance practice.

Modern construction is characterized with complex designs, new and innovative materials that are sensitive with high precision. In addressing the accompanying challenges, mechanization of construction process is said to be the guarantee especially in this era of crash programmes and advancement in technology to reduce poor workmanship and eliminate avoidable holdup in construction processes in the industry. Amidst this belief, attributes of construction industry in Imo state still reflect ineffectiveness in the use of plant and equipment. Hence, the study assesses the involvement of plants and equipment in building delivery for improved project performance. Field survey and work measurement methods were adopted to gather both non-parametric and parametric data respectively. The survey design targeted the sampled building professionals while work measurement focused on selected earth and concrete works in the area of the study. Inferential and descriptive statistical tools of Chi-square on likert scale and Comparative measurements on work activities respectively were used to analyze the respective non-parametric and parametric data. Findings show that selection of various plants are dependent on their rates of use for increased site work productivity; while the socio-economic and political issues as militating factors against effective use of plants are determined by their levels of acceptance. It was also discovered comparatively that mechanization of construction processes is more time and cost effective in building project than manual approach at work. The study therefore recommends that a systematic and holistic awareness be created by the stakeholders on the usefulness of mechanization of construction process in physical development. Besides, government should enforce construction methodology plan as a mandatory document for approval of any building plans; while frantic effort should be targeted at reviving the abandoned steel manufacturing industry at Ajeokuta, Ogun state to revolutionize the construction methodology of construction industry in Nigeria.

The Impact

The construction sector as one of the parties using natural resources in the form of manufacturing or natural material needs to evaluate the activity of the construction process. Indonesia as a developing country requires various types of infrastructure, one of which is building construction. Various studies show that the impact of the construction process produces a large number of wastes and causes a decrease in the number of non-renewable materials. One of approaches to organize those impacts is by applying the principle of green construction. In Indonesia, this principle has not been clearly defined the meaning and the size that will be used. The purpose of this research is to develop green construction assessment model for building construction in Indonesia to improve the performance of contractor in the construction process. The scoring model is developed hierarchically composed of aspect, factor, and green construction indicator using additive model. The test model was carried out in three different project characteristics, reflecting the combination of planned green construction and green contractors. The result of green construction assessment model is able to represent the fact that occurred in the construction process.

Total factor productivity (TFP) is of critical importance to the sustainable development of construction industry. This paper presents an analysis on the impact of migrant workers on TFP in Chinese construction sector. Interestingly, Solow Residual Approach is applied to conduct the analysis through comparing two scenarios, namely the scenario without considering migrant workers (Scenario A) and the scenario with including migrant workers (Scenario B). The data are collected from the China Statistical Yearbook on Construction and Chinese Annual Report on Migrant Workers for the period of 2008–2015. The results indicate that migrant workers have a significant impact on TFP, during the surveyed period they improved TFP by 10.42% in total and promoted the annual average TFP growth by 0.96%. Hence, it can be seen that the impact of migrant workers on TFP is very significant, whilst the main reason for such impact is believed to be the improvement of migrant workers’ quality obtained mainly throughout learning by doing.
