Investment Capital

The largest share of investment capital in all developing countries finds its way in to construction. In our India construction industry are growing rapidly. The development of construction industry is the bare for all industrial activities in any developing country, since the economic progress depends on the investment of the capital for future production; the rate of construction activity has a significant effect upon the economic health of the nation and its future growth. Construction equipment plays a significant role in the execution of modern high-cost time-bound construction projects. Equipment is an economic investment and the contractors must apply time value analytical formula to the process of machine utilization. The most important aspect of estimating and building a construction project is determining production and cost and controlling both during the progress of work. The planning & selection of equipment is depends upon construction structure, location, and various construction methods. Also that depends on various construction operations. This study emphasizes the vital role of construction equipment in construction industries to optimize the profit by reducing the labour hours and also aimed to identifying the best practices of improving the productivity of construction for the Indian scenario. With this aid planning would be more systematic, logical and efficient as resource allocators and managers would be aware of output for particular equipment.

Hierarchy Process

Sustainable procurement is an emerging theme in the construction industry across the globe. However, organizations in the construction industry often encounter impediments in improving environmental performance in construction projects, especially in procurement. Besides its other facets, procurement of construction equipment is inherited to be capital-intensive and vital for managing environmental concerns associated with built environment projects. In this regard, selection criteria in such procurement processes are generally supportive of considering cost and engineering specifications as key parameters. However, sustainability apprehensions in today’s Malaysian construction industry have mounted pressure on industry professionals to rethink their equipment acquisition strategies. The notion of green or sustainable procurement is still infancy for the Malaysian construction industry and facing challenges for embedding it in the current procurement practices. This research aims to address these apprehensions by considering six main criteria, namely, life cycle cost (LCC), performance (P), system capability (SC), operational convenience (OC), environmental impact (EI), and social benefits (SBs), and their 38 subcriteria towards procurement of sustainable construction equipment. A multicriteria-based equipment selection framework on the triple bottom line of sustainability in the context of the Malaysian construction industry has been developed and tested. The application of analytical hierarchy process (AHP) established the sustainable procurement index with a consistent sensitivity analysis results. As such, the proposed procurement index shall help decision-makers in the process of the acquisition of sustainable construction equipment in Malaysia.

Cross Case Analysis

Carbon estimating plays a vital role in the construction industry. The current focus on introducing zero-carbon construction projects reduces operational carbon, at the expense of Embodied Carbon (EC). However, it is important to reduce overall net carbon emissions. There are various methods to estimate carbon, but the accuracy of these estimates is questionable. This paper reviews a novel methodology, the Supply Chain based Embodied carbon Estimating Method (SCEEM), which was introduced recently to accurately estimate EC in construction supply chains. SCEEM is compared against existing EC estimating methods (Blackbook and eToolLCD) using a case study approach. It is also supplemented with a comprehensive literature review of existing EC methods. The EC values calculated using Blackbook and eToolLCD were mostly higher than SCEEM. Since SCEEM uses actual site data and considers first principles-based value addition method to estimate EC, it is considered accurate. The cross-case analysis revealed that SCEEM provided consistent results. Hence, SCEEM is recommended to accurately estimate EC of any type of project.

The Impact

Mobile computing technology has an enormous potential in civil engineering, mainly in the field of construction management. This paper presents an approach by using mobile computing in a civil engineering construction project, exploring how information can be exchanged at a construction site, and how billing of quantities (BOQ), drawings and specifications are shared for the benefit of the project. One of the major obstacles in using information technology (IT) when applied to civil engineering is due to the dynamic changes in the construction activities and the diversity of construction methods as compared to other industries. This has proved to be a great disadvantage when trying to give construction sites adequate IT support. Computers require infrastructure, which can be transferred easily to the head office, but rarely to the construction site itself in a systematic way. Therefore, the impact of IT on the way the construction industry actually works has not been significantly utilized. This paper consists of two main parts. The first part defines the concept of mobile computing, describes some recent research, and stresses the potential for the construction industry. The second part is focuses on an approach, implementing mobile computing in a real construction site.

The public procurement sector plays a vital role in the economic development in developing countries such as Vietnam. However, public procurement activities usually perform poorly. This situation can be attributed to ineffective procedures and system (“hardware”) and human resource management (“software”), which occurs at every stage in project purchasing. The poor performance has reduced the effectiveness and efficiency of project delivery in the construction industry, causing delays, cost over-runs, and defects in construction projects. This paper, through working experience and observation by the first author, problems of public procurement were obtained as hypotheses and then validated based on questionnaire surveys and CIS (Construction Industry Structure) model analysis. The survey results indicated a relative correlation with CIS model in description of current construction industry. The study aims to identify issues of public procurement at all stages: pre bid, bid information, evaluation, and award. Based on identified major problems and determined risks, the results are expected to provide a valuable perspective, and thus, to propose necessary strategies to deliver high performance, competition and transparency for the public procurement. In further studies, it is relevant to propose a new model for sustainable public procurement based on the best value approach.

The Impact

To further enhance the efficiency, capacity and capability of the Malaysian construction industry, the government has been aggressively championing the use of Industrialised Building System (IBS). However, several studies have pointed out that the trade contractors are very concern with the increasing use of IBS in the country because it will reduce their business opportunities.  Therefore, the research is dedicated to address issues faced by the trade contractors with the adoption of IBS. The objectives of this paper are to uncover the impact of IBS to the trade contractors and to suggest solutions to address issues faced by the trade contractors with the implementation of IBS. A fundamental of the methodology is to adopt multiple case studies approach. These projects adopted both conventional and IBS construction method. A number of 8 projects were selected. Interview sessions are conducted with trade and main contractors. Collected data is then modelled by using the combination of fuzzy theory set and simple multi-attribute rating technique. Main contractors’ input on several success factors that lead to the penetration of trade contractors in IBS is evaluated. Some degree of involvement of trade contractors in IBS projects is recommended. It is significant for the trade contractors to obtain skills for IBS approach besides their existing crafts. Furthermore, the trade contractors are suggested to register themselves as IBS components installer as this does not involve high investment capital or they can join the other companies to increase their technical and financial capacity. These findings will inform on numerous policy initiatives to manage the business sustainability of the domestic trade contractors, to improve construction methods, then to modernise and upgrade the construction industry within the country.

PurposeLabours are one of the key resources of construction projects having a significant impact on economic development. With time, the construction industry is getting a boom due to numerous construction projects in which labours’ contribution is significant. Project betterment is associated with the project productivity which relates to the labours. Wages play a vital role in retaining labours in the construction industry.Design/methodology/approachThis study focuses on investigating the increasing and decreasing behaviour of labour wages in the construction industry and observing the impact of the inflation rate in deviating labour wages. Initially, the percentage deviation was calculated to observe the changing behaviour of the data and then the Spearman correlation test was used to find the relationship between the inflation rate and the labour wages.FindingsIt is evident that even with a good economy and a stable construction sector, still, the labour wages faced a decline over time, which is a matter of concern. Also, based on the correlation coefficient, it was revealed that several labour wages categories are moderately and strongly correlated with the inflation rate and can impact project cost if the inflation rate is not considered while finalizing the budget. Besides that, the changing behaviour of labour wages due to the inflation rate impacts significantly on gross domestic product (GDP); therefore, it requires vital attention.Originality/valueChanges in labour wages are not considered in budget estimation which drag the project towards cost overrun. This study brings the attention of the stakeholders on the issue with experimental justification. Also, how the inflation rate is affecting the labour wages has also been addressed.
