Significance Levels

Rapid growth in construction activities as a result of a growing population and urbanization in many parts of the world generates a large amount of waste from construction. To reduce and manage these wastes, a comprehensive understanding of the construction waste generation factors is needed. The purpose of this study is to identify the contributing factors of construction waste in Thailand’s construction industry. The causes of construction waste were identified through an extensive literature review. A total of 28 causes of construction waste were identified and grouped into the four categories: design and documentation, material and procurement, construction method and planning, and human resources. To determine the significant level of each factor, a structured questionnaire survey was carried out to gather information from contractors about causes of construction material waste. The results show that the categories contributing to construction waste ranks as design and documentation, human resources, construction methods and planning, and material and procurement, respectively. Meanwhile, factors from each category were also determined and ranked. Design change, inattentive working attitudes and behaviors, ineffective planning and scheduling, and material storage were among the highest impact factors on construction waste generation in each category. Identifying the significance levels of waste generation factors will help the industry’s stakeholders build suitable strategies to manage construction waste more effectively.

Development of the infrastructure is favorable for the growth and economy for any country; however, the issues to manage construction waste due originating from development exercises is a noteworthy reason for concern. The waste from construction contributes to negative repercussions on time, cost, productivity, and environment. Therefore, to reduce these negative and undesirable effects, a detailed review of waste generation and management must be provided. The significant construction waste causes were identified and grouped into seven clusters: construction management, design, construction material procurement, construction material handling, construction site condition, and external factor. A total of 150 questionnaire survey forms were distributed to professionals working on the Riyadh metro project, and only 118 questionnaire forms were received. The collected data from the questionnaire is analyzed using the average index and factor analysis. Analysis identified that ‘Design errors; ‘Accidents; ‘Damage during handling’; ‘Communication problems; ‘Frequent variation orders’ ; ‘Congestion of the site’ and ‘Damage caused by workers’; are highest significant causes in each category respectively. Furthermore, factor analysis was conducted through Exploratory Factor Analysis (EFA) technique to the top fifteen (15) factors and found five factors responsible for the construction waste was identified such as management, workers issues, material related issues, improper handling, and design. The findings from this study are useful for policymakers to develop or/and enhance recommendations on construction waste generation to prevent problems in construction industries. The government or building industry should establish or strengthen regulations that regulates how construction materials should be disposed of.

Waste Generation Rate

High construction waste (CW) generation in Malaysia has serious impacts although there are very little available data regarding the relevant issue in Malaysia. This lack of data results in improper CW management and CW disposal without proper control measures. To control the implications of CW, it is very important to understand their quantity which is currently unknown. Past researches in Malaysia, found that CW generation was affected by construction methods (CMs) practiced on site. The aim of this study is to compare the CW generation rate between different CMs for on-going construction projects in Malaysia. Common CMs practiced in Malaysia are conventional construction method (CCM), mixed construction method (MCM) and industrialized building system (IBS). To obtain CW generation data, site visit (SV) method, which consists of direct measurement (DM) and indirect measurement (IM) is applied to this study. CCM was recorded to have the highest amount of waste (197.657 tons). IBS method records 77.188 tons and MCM 53.191 tons. Regarding the average waste generation rate (AWGR), IBS recorded a value of 0.018 tons per square meter, while MCM recorded 0.030 tons per square meter and CCM recorded the highest amount of 0.046 tons per square meter.

Project Life

Waste generation is a major issue faced by construction projects. Construction waste has adverse effects the time, cost, productivity and economy of the industry. There are different causes of waste generation in different countries of the world. An extensive literature was carried out to identify the common factors of construction waste generation which resulted in identifying 59 common attributes. Through structured interview data was collected to classify the attributes on different stages of construction project lifecycle. A total of 15 experienced practitioners were interviewed classify the attributes into different stages of project life i.e. planning, design, construction and finishing. Frequency analysis of the perception of the practitioners showed that there are 25 attributes in planning stage, 9 in design stage, 53 in construction stage and 5 in finishing stage. From the findings it can be seen that construction stage is the critical stage in which 53 attributes are occurring. This study shows that the practitioners need to be very careful during construction phase for controlling construction waste generation.

Attitudinal Changes

Purpose – Construction waste originates from various sources, generally from the inception of construction through to the completion of a building project. Previous research has shown that there is a link between the quantity of waste generated and the way labour is organized in the construction industry. However, these studies have failed to look into the sources of waste with respect to labour utilization and how it influences the generation of waste. The purpose of this paper is to investigate the influence of labour arrangements on construction waste generation, particularly the sources of waste and the attitudes of workers. Design/methodology/approach – Using a combination of direct observations and source evaluations on six case study sites, the waste in direct and subcontracted labour (SL) arrangements was quantified. A questionnaire survey was administered to the workers participating in the observation study to elicit their attitudes to waste and closely linked issues. Findings – The results show that SL produced more waste than direct labour in all three work processes considered. A lack of organizational commitment and effective strategy emerged as the main problem in waste reduction. Practical implications – Subcontractors should be made responsible for their share of waste generated in a project. Main contractors should record who are “approved subcontractors” based on their performance at site which should include inter alia waste generation. The approved subcontractor method is a way of barring subcontractors from being included on future projects if they do not meet the performance standards of a main contractor. Originality/value – This study shows that waste generation has a relationship to organizational commitment and strategy rather than to workers’ attitudes. In order to manage construction waste effectively, it has to be considered in the financial equation of a project, because attitudinal changes are difficult to achieve unless there is a personal financial benefit attached to it.

Decentralised System

The discourse on decentralisation in developing countries is seen as a strategy in restructuring and improving economic, social and public welfare including the education sector. This idea is fundamentally in line with the goals of Education for All (EFA). The experience of Indonesia that had shifted from a strongly centralised system to a decentralised one in the early 2000s provides an interesting case. This article argues that the current decentralised system in education has seen an insignificant effect in achieving EFA. Through an extensive literature study, this article draws attention to the  particular concerns of human resources, curriculum, corruption and poverty issues as contributing factors to the seemingly failing efforts in the decentralised settings, all in the light of Indonesia's historical development.

Using Data

This study examines construction waste generation and management in Taiwan. We verify the factors probable affecting the output of construction wastes by using data for the output of declared construction wastes produced from demolition projects in Taiwan in the last year, expert interviews, and research achievements in the past, and find “ on-site separation” is the factor with effects on the output of construction wastes via cross-correlation by algorithms such as K-Means and Decision Tree C5.0. It can be seen that the output (0.092(t/M3) with on-site separation or 0.329(t/M3) without on-site separation is highly correlated with the composition ratio of construction wastes and referred to as a valid conclusion.

Wooden Structures

Construction industry creates an environment for people's lives. On the other hand, construction activities have a negative impact on various aspects of the environment. It consumes natural raw materials, significantly contributes to carbon footprint, waste, etc. Appropriate choice of constructional, material, technical, technological and environmental parameters of buildings can partially reduce this negative impacts. By designing, implementing and using wood-based constructions it is possible to reduce the negative impact in the area of construction waste generation. Currently, the construction market offers a large number of construction systems of wooden buildings, which have both strengths and weaknesses. In this paper are identified construction systems of wooden buildings offered on the Slovak construction market. The aim of the paper is a detailed identification of construction waste generation during the realization of particular wooden structures and monitoring of waste generation in production factory (off site) and on construction site (on site) during the construction of wooden buildings. Based on the obtained information, the individual construction systems of wood-based constructions are compared in terms of construction waste generation
