The compaction quality of the subgrade is directly related to the service life of the road. Effective control of the subgrade construction process is the key to ensuring the compaction quality of the subgrade. Therefore, real-time, comprehensive, rapid and accurate prediction of construction compaction quality through informatization detection method is an important guarantee for speeding up construction progress and ensuring subgrade compaction quality. Based on the function of the system, this paper puts forward the principle of system development and the development mode used in system development, and displays the development system in real-time to achieve the whole process control of subgrade construction quality.

Sharing of the risk and liability is one of the most important functions of construction contracts. Proper sharing of the risks and liability between the parties of construction contract has a rather big influence on efficiency, quality, and probability of arising disputes between the parties of construction contract in construction projects. A lot of risk exists during the fulfillment of construction projects. One of those risks is the risk of defects of building products. The question of the liability of the parties of construction contract for inappropriate quality of the construction production caused by a bad quality of building products mainly depends on sharing of the risk of defects of building materials in the construction contract. Some aspects of the mentioned risk and liability of the parties of the construction contract might be set by mutual agreement in the construction contract. The other aspects are regulated by imperative norms of the law and the parties of construction contract have not a right to change those imperative conditions of sharing of risks and liability. The article deals with sharing of risk and liability for supplying building products of an improper quality for construction, taking in to account conditions of construction contract, legal regulation and behavior of parties of a construction contract. A tree of forming the alternatives of liability is presented in the article. Liability for supply of defected building products arises not only for parties of a construction contract. The producer (supplier) of building products is responsible for this as well. Variations of liability of the producer (supplier) depending on construction contract conditions are analyzed. A matrix of liability of the producer (supplier) of building products is presented in the article.

With the increasing number of urban underground construction projects, the evaluation of the influence of tunnel expansion on building foundation is one of the important factors to be considered in the project. In this paper, the deformation of the upper structure and the deformation pattern of the upper structure were analyzed, and the two-dimensional finite element model was built based on the case of Chongqing Jiefangbei Underground Ring Road Expansion Project Scheme. Comparative analysis of the deformation and changes in stress of the two tunnel expansion construction schemes of full-frame support and bolt suspension was performed, and the safety, rationality and feasibility of the bolt suspension scheme was confirmed through project safety analysis. It is hoped that this paper will serve as a reference for similar projects in the safety control technology of tunnel construction process.

Purpose This paper aims to assess COVID-19 (C-19) pandemic influence in the 37 factors identified from extant literature as factors influencing the viability of local construction firms (LCFs). Design/methodology/approach A sample size of 65 staff of 31 LCFs that were awarded construction projects contracts in institutions in Nigeria was purposefully selected and accessed based on relevant predetermined criteria. Respondents’ views on factors determining the viability of LCFs were obtained. Factors known to be influenced by C-19 are 25 of the 37 factors rated on a five-point Likert scale of importance by the respondents. Mean scores were used to rank the factors and principal component analysis was used to obtain key component factors (CFs) influenced by the C-19 pandemic. Findings Six of the first ten “extremely important” and “very important” factors are known to be influenced by C-19 pandemic. A total of 8 CFs having 20 variables with factor loadings of more than 0.5 each were known to be influenced by C-19. The C-19 pandemic influenced LCFs’ cash flow and management of construction labour, plant and equipment amidst variables that had above 0.8 factor loading. Research limitations/implications A limitation of this study is the inability to conduct close contact interview during this period to obtain personal views on the influence of C-19 on LCFs. However, this does not reduce the quality of findings of this study, as there are valid literature basis hinging this study findings. Practical implications The paper recommends that all stakeholders pay prompt attention to the factors adversely affected by the C-19 pandemic to improve or at the least sustain the viability of LCFs. Originality/value This paper fulfils a present pertinent need of assessing the influence of the C-19 pandemic on various factors influencing the viability of construction firms.

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.

With the rapid development of our economy, also promotes the development of our country road. Though the road construction starts relatively late in our country, but its development is very quick. However, due to the technology is not very mature, and the road load is bigger, and the influence of climate and so on, makes appeared different degree of damage of asphalt pavement. So how to improve the quality of the road is also became a problem to be solved in engineering. This article mainly from the problems existing in the construction process, the influence of natural factors and human factors, analyses the reason of pavement damage, and how to detect damage of asphalt pavement.

Social Importance

The quality of roads dictates the development of the country as well as the quality of lives of its citizens. To maintain the road sections at the desired level of service, adequate and timely maintenance works are necessary. But maintaining all the road sections every year is not possible for developing countries like India. These works get constrained by limited budget and hence utilization of the budget becomes crucial for the concerned government department. Out of hundreds of road sections, the department can select only a few at a time. But most of the times, the procedure of filtering out these few sections is not scientific and hence gets influenced by some undue external factors. Looking at these problems, the authors perceived an urgent need of an accessible and user-friendly mobile application that does the prioritization process. The works in this paper describes the development of an android based application which considers the four important domains of any road section viz. pavement functional distress, roughness, social importance and pavement structural strength. From the user inputs related to these four domains, the application accordingly computes and displays a priority score, on the basis of which the user can select the road sections for maintenance works. The validation of the application results has been performed and some test results will be added in the full-length paper.
