An investigation on benefits and future expectation of Industrialised Building System (IBS) implementation in construction practices

Industrialised Building System (IBS) is well known in many developing countries due to the benefits that can be derived from its applications in construction projects. However, the low percentage of IBS usage may be due to lack of awareness and knowledge about IBS among many professionals. There may be factors that contribute to a lack of interest from the client towards IBS. The aim of this study is to improve the application of IBS particularly in private construction projects in Malaysia by determining the benefits and expectation on application of IBS in private construction projects. This study adopts a quantitative method using questionnaires that were sent to 35 construction firms as a sampling frame. Finally, the finding of this study hopefully could assist professional parties in construction industry in providing a better ground knowledge for improving decisions making to achieve the success of IBS construction projects implementation and also this study will achieved the project objectives in terms of predetermined objectives that are mostly within the time, specified budget and standard qualit

Mitigation measures for significant factors instigating cost overrun in highway projects

Construction industry has created numerous employment opportunities and playing a role model in economic growth of Pakistan. This industry is facing serious and critical problem of cost overrun especially in highway sector in country Pakistan particularly in Sindh Province. The purpose of this study is to identify mitigation measures for significant factors of cost overrun in highway projects of Sindh Province. In this study, mixed-mode research approach has been used. Quantitatively, a structured questionnaire based on 64 common factors of cost overrun from in-depth literature review was developed and distributed to30 selected respondents among the client, contractor and consultant having more than 15 years of experience in handling highway projects in Sindh Province. The collected data was statistically analyzed using SPSS where 8 most significant factors of cost overrun were identified. Qualitatively, the identified eight most significant factors were then incorporated in open ended questionnaire and distributed to 30 selected experts for them to write possible mitigation measures for each of the significant factors. The data was then analyzed through content analysis technique to rank the mitigation measures according to their substantiality. The results of this study would be helpful for construction practitioners to be used as reference in taking up appropriate measures in controlling cost overrun in highways projects in Pakista

Improving thermal conductivity of fired clay brick using sawdust waste

The demand for energy efficient design and construction has become progressively important with the growing energy costs and increasing awareness on the effects of global warming. Global warming causes a higher temperature of the surrounding, which will give significant effect to the energy consumption in commercial and residential building. Therefore, this study aims to investigate the possibility of incorporating sawdust as an additive material to improve thermal insulation properties of clay brick through lowering its thermal conductivity value. This study uses three types of soils with the proportion of clay soil (80%), laterite soil (10%) and grey soil (10%). The percentages of sawdust waste used as an additive are 2.5%, 5% and 7.5% by weight. The laboratory works performed involve the geotechnical gradation, physical, mechanical, chemical composition and thermal conductivity of fired clay brick. There are two types of brick that were produced in this study, which are control brick (CB) and sawdust brick (SB). The results show that the thermal conductivity of fire clay brick improves with the increasing percentage of waste material. Therefore, in this study, it appears that the brick incorporated with 5% of the sawdust waste is the optimum value that can achieve 7.5 MPa of compressive strength, 23.01.56% of water absorption and 0.384 W/m˚C of thermal conductivity. Thus, 5% of sawdust waste is chosen as the optimum percentage that yields better fired clay brick. This study reveals that the sawdust is a potential waste material that can be used to improve the thermal property and as a sustainable construction material

The smartphone technology acceptance among Malaysian young adults

Smartphone technology can be characterized as multi-function device that helps people to manage their task. This study is being emphasized because there is no legitimate answer in Malaysian context whether perceived usefulness had contributed an impact on smartphone technology acceptance. Therefore, there is a need to explore how perceived usefulness affect smartphone technology acceptance among Malaysian young adults. This study was conducted using (TAM) model to capture detailed view about perceived usefulness and the relationship with smartphone technology acceptance among Malaysian young adults. The findings of this study confirmed that perceived usefulness drives the smartphone technology acceptance among Malaysian young adults and it cannot be denied that the advanced features of smartphone technology had influenced Malaysian young adults to possess smartphone technology and make use of it for their personal tasks

Theoretical framework of the causes of construction time and cost overruns

Any construction practitioner fundamental goal is to complete the projects within estimated duration and budgets, and expected quality targets. However, time and cost overruns are regular and universal phenomenon in construction projects and the construction projects in Malaysia has no exemption from the problems of time overrun and cost overrun. In order to accomplish the successful completion of construction projects on specified time and within planned cost, there are various factors that should be given serious attention so that issues such as time and cost overrun can be addressed. This paper aims to construct a framework for the causes of time overrun and cost overrun in construction projects of Malaysia. Based on the relevant literature review, causative factors of time overrun and cost overrun in Malaysian construction projects are summarized and the theoretical frameworks of the causes of construction time overrun and cost overrun is constructed. The developed frameworks for construction time and cost overruns based on the existing literature will assist the construction practitioners to plan the efficient approaches for achieving successful completion of the projects

Identifying causes of construction waste - case of central region of Peninsular Malaysia

Construction waste becomes a global issue facing by practitioners and researchers around the world. Waste can affects success of construction project significantly. More specifically, it has major impact on construction cost, construction time, productivity and sustainability aspects. This paper aims to identify various factors causing construction waste in Malaysia. Study was carried out through structured questionnaire focusing three major parties (i.e. clients, consultants and contractors) involved in construction project. Data was analyzed with Statistical Software Package SPSS. Reliability of data was found as 0.917 which showed that data collected was highly reliable. The calculation of Mean Rank of the construction waste causes found that the 5 key causes are Poor site management and supervision, Lack of experience, inadequate planning and scheduling, Mistakes and errors in design and finally Mistakes during construction. Spearman correlation analysis showed that Mistakes during construction was highly correlated with Rework (with 0.829 correlation value) and Slow information flow between parties (with a value of 0.60) and vice versa. Through identifying the causes and its correlation of the construction waste it gives better understanding to the construction community for future construction projects which benefit not only in term of economy but also the environment
