Highway projects involve huge capital investments and prolonged durations. A number of researchers have developed various computer-based tools and techniques to help planners prepare plans and schedules based on their specific needs. CPM is the predominant scheduling method used in construction industry. However, its inability to efficiently plan and schedule repetitive projects such as highways has widely been recognized. Linear scheduling method on the other hand, was specifically designed and developed for repetitive projects. The aim of this paper is to study various planning and scheduling methods discussed in the literature and evaluate their suitability for highway projects. On the basis of literature study, location based planning utilizing linear scheduling method seems to be the most logical and efficient way of planning highway projects for various reasons discussed in the paper. It is however a new concept and therefore has limited use in practice.

Although the general consensus is that linear scheduling methods (LSMs) are quite powerful, their use in construction has been very limited. The linkage between the characteristics of scheduling methods and the requirements of the tasks performed by schedulers has been an on-going concern in the construction industry. This study proposes a “task-technology fit” model to understand why LSMs are not being used as extensively as expected. The model aims to determine whether the characteristics of LSM (technology) satisfy the duties and obligations of construction schedulers (tasks). By scrutinizing the task-technology fit in LSM applications, deficiencies can be detected which hinder the wider use of these methods in the industry. A questionnaire survey was administered to measure task-technology fit in LSM applications. The target population included schedulers, project managers, construction managers, and other professionals listed in the directory of the Construction Management Association of America (CMAA). The findings indicate that LSM is effective in repetitive projects and is able to provide a smooth and efficient flow of resources by adjusting activities’ rate of production. In addition, research findings point out that LSM effectively shows activity sequences as well as progress. However, the findings also reveal that LSM is not applicable when reliable resource data are not available. It should also be noted that very few software packages that perform LSM scheduling are commercially available on the market.

Study Results

Many scholars claimed that due to maintenance, high reconstruction and construction costs in Malaysia, LCC shows an important role in estimating the cost of rigid pavement. Because of the government's expenditure and high budget allocation on pavement rehabilitation and maintenance work in Malaysia, choosing the most cost-effective pavement maintenance, maximizing the budget allocation and rehabilitation alternatives is essential for transportation agencies. A useful technique LCC of economic analysis that measures the different solutions of cost-effectiveness to rehabilitation and maintenance within the same category of roads. To generate a broad and accurate LCC output, however, it is necessary to ensure that the value information inputs are ready and of sufficient quality to use in the estimation of the LCC. This article shows the findings of Malaysia's systematic literature review inputs for LCC cost information study of dynamic pavement rehabilitation and maintenance. The literature study results showed that the greater part of key players in the construction industry are aware of the need for LCC analysis in the rigid rehabilitation and maintenance of the pavement. In Malaysia the LCC current state system of rigid pavement rehabilitation and maintenance, however, is still in its not only infancy stage but also is not ready for the difficulties to be implemented in achieving quality cost data to generate a reliable and comprehensive analysis of life cycle cost. The present findings of the paper which provide information on cost data current state inputs in the construction industry from the LCC analysis of rigid pavement rehabilitation and maintenance.

The presented study aims to examine the current state and development prospects of self-regulation in the Russian construction industry.Aim. The study aims to conduct a comprehensive analysis of the current state and development prospects of self-regulation as an institution of public administration, identify the problems of self-regulation in the construction industry, and formulate proposals on solving the identified problems.Tasks. The authors complete the following tasks to achieve the set aim: examine the regulatory framework of the activities of self-regulatory organizations in the construction industry — construction, design, and engineering surveying; analyze the current state and positive trends of self-regulation in the field of construction; identify problems in the activities of self-regulatory organizations in the construction industry — construction, design, and engineering surveying — and development prospects of the examined alternative to government regulation.Methods. The methodological basis of the study comprises the fundamental provisions of the modern economic theory, theories of public and municipal administration and legal sciences. The information base includes regulatory and legal acts of the Russian Federation on self-regulation in the construction industry, data from the State Register of Self-Regulatory Organizations, and statistics in the field of construction.Results. At the current stage of development of self-regulation in the construction industry, the most efficient mechanism for this institution involves guaranteed compensation for damage caused due to shortcomings in the works and services during construction, renovation, capital repairs of construction objects, engineering surveying, design. The victims should be compensated not out of insurance payments under civil insurance contracts, but rather out of the compensation funds of self-regulatory organizations.Conclusion. This study makes it possible to assess the institution of self-regulation in the construction industry — construction, design, and engineering surveying — as an efficient institution for proper protection of the interests of consumers of construction works and services and those of the government.

Introduction. The processes of globalization and social transformation have made environmen-tal conservation a priority, and therefore require some action to be taken to address environ-mental issues and the rational use of natural resources. The solution of the existing problems depends to a great extent on the functioning efficiency of the financial security system established in the country, the established composition and the volume of financing sources and certain directions of their use, which necessitates their scientific-based analysis. The purpose of the study is to investigate the state of financing environmental measures in Ukraine, to study the directions, dynamics and structure of costs for environmental protection, identifying features of financing environmental protection. Results. The comprehensive analysis of the dynamics of costs for environmental protection and rational use of natural resources is carried out. The main components of environmental expenditures are identified. Costs for environmental protection and rational use of natural resources by financing sources have been structured. The dynamics and structure of capital investments by nature conservation measures are investigated. The dynamics of the share of expenditures for environmental protection and rational use of natural resources in the GDP of Ukraine, as well as the share of capital investments (environmental) in the structure of capital investments of Ukraine are analyzed. The features of the current state of financing environmental protection and rational use of natural resources are highlighted. Conclusions. The results of the research made it possible to identify the main problems in the field of financial support for environmental protection and to outline the ways of their solution. The necessity of investments mobilization into nature protection activity is proved through development of appropriate means of economic stimulation and their legislative fixing, which will allow to solve the problem of financial support of environmental protection by diversification of financing sources.

The churches of the Broumov region are renowned for their unique baroque architecture, their distinct shapes, and sizes. They are an integral part of the Czech cultural heritage. If you analyze the churches, it becomes evident that both the local geological conditions and the municipal economic situation have played an important role in their current condition. Moreover, the local construction industry has been significantly affected by historical events. In this article we would like to present the effects of those factors on the current state of selected churches, namely on the bearing capacity of their walls. Besides being very interesting, it also plays a key role in the maintenance and the potential reconstruction of the churches.

The Subject

Purpose The purpose of this paper is to explore the current state of popular modern methods of construction (MMC) and pre-manufactured construction in the construction industry and propose a framework for future implications for practice and future research. Design/methodology/approach This technical paper is based on a narrative review of the extant literature on the subject. First, the Scopus search engine was used to retrieve relevant papers on MMC, offsite and pre-manufactured construction. Second, institutional literature such as reports by industry professional and trade bodies, literature from leading technology firms and contractors with experience of MMC were extracted. These two strands of literature were synthesised and a comprehensive discussion on the topic was provided. Findings Results show that journal publications on MMC and pre-manufactured construction have increased in the past decade. The paper found significant advances in the development of premanufactured and offsite construction approaches with many benefits. Offsite and pre-manufactured construction are viable and sustainable systems currently suitable for wider adoption as the mainstream construction method. Research limitations/implications This technical paper based on an integrative review of relevant literature could have benefitted from interviews of professionals with experience of offsite and pre-manufacture techniques and from wider availability of current academic publications on the subject. Validation of the framework has not been undertaken. Originality/value Not much-published work has been undertaken on the current state of development globally and the viability of these construction approaches. This paper evaluates evidence from academic and industry sources to address this gap. A framework has been developed which can help the industry’s industrialisation drive.
