Cost performance is the fundamental criteria for success of any project. Most projects face huge amount of cost variations in Nigeria construction industry. Its performance is based on the three major parameters which include, cost, time and quality. This research was carried out to analyze elemental cost variation in building construction projects in Abuja Nigeria. Secondary data was obtained for the study and analysed using ANOVA, correlation, and regression. The result shows that the most critical factors that contribute to cost variation include unstable economy, improper planning, inaccurate estimate and fraudulent practice. The study finally recommended the best way of a averting the problem which include stabilization of the economy by the government through monitoring of price, stability of cost of labor and building materials. Contractors should employ qualified and experience staff in order to be able to follow the different technical and managerial aspects of the project. The study has concluded that there was no significant difference amongst the variation in the costs of selected groups of building elements. This was based on analysis of variance results. This meant that notwithstanding the magnitude of changes to elemental costs, no single element could be isolated as being exceptional in terms of cost variations. It was concluded that in terms of degree of influence on change in initial contract sums, the Services elements was ranked 1st, based on an R2 value of 25.2%. Substructure had the least influence on changes in the initial contract sum (R2 value of 6.71%).

Building project as one of the construction services are filled with varying risks during the construction phase of the project implementation. At the stage of the project implementation, risks may arise either the risk of time, cost and those which affect the quality of the project. Therefore, we need to understand the risks at the construction phase and mitigation to the risks to meet in execution of project based on initial planning. The study was conducted to identify the risks in the implementation of construction projects of government buildings by using survey methods that aim to get the opinion of the respondents regarding the risks at implementation of the government building construction projects in the city of Dili - Timor Leste. Further, it was done a risk assessment to determine the major or main risks. Major risk is controlled through mitigation measures and allocation of risks to the parties directly involved in construction projects such as Project Owner, Technical Supervisor, Consultant Design, Consultant Supervision and Contractor. The analysis used in this study is a qualitative analysis. The results showed 64 risks identified in the implementation of construction projects there are 10 government buildings risks (16%) with an unacceptable category, 18 risks (28%) with the undesirable category, 28 risks (44%) with acceptable category and 8 risks (12%) with negligible category. Ownership of major / main risk to the parties directly involved in the implementation of construction projects such as the project owner, technical supervisor, consultant design, consultant supervision and contractors. The project Owner and Technical Supervision (Department of Public Works) is expected to further enhance the ability to manage projects so not throwing responsibility in managing government projects. consultant design and sonsultant supervision to be more careful in design till supervision during the implementation period so as to meet the cost, quality and time planned. Contractors are expected to further improve the performance of the building construction project.

The Cost

Project’s cost is one of important components in project achievement. Because of the uniqueness of construction projects, cost estimation always differs from project to project. The rate of cost components always change over time make difficult to forecast the cost for the upcoming project. The cost component consists of many influencing variables where there is interrelationship each other affecting to the total project cost. This paper objective is to develop a cost prediction model to assist the project planners in cost estimation for future projects. System dynamic is one of the appropriate methods to analyse system behaviour with interrelationship referring to the historic data, so it is able to predict the future project. Developing the model, primary and secondary data are collected from previous studies, interview with the government planner and survey in Malang Regency. The model simulation is Brick work unit with its components. Data from last thirteen years are used to verify and validate the developed model by causal loop diagram as a basic method in system dynamic. The finding showed that the model is closed to real condition through the validation mechanism. The developed system is useful in decision making of budget planning based on work quantity.

  Conventional buildings consume large amounts of energy and are the source of greenhouse gas emissions contributing to climate change. The shortage of green buildings in Pakistan have been said to be due to shortage of knowledge of the benefits of essential green building materials and the absence of  a regulatory framework. The study is qualitative and quantitative and is divided into two parts. This review paper focuses on awareness in the Pakistan's local construction market concerning green buildings through a survey questionnaire. Data collection procedure consists of 60 questionnaires related to green building construction awareness and priorities within Karachi's construction sector. Also, a focus group and personal interviews conducted with at least 5 professionals working in local construction projects are analyzed. The research questions formed from detailed literature review were analyzed and found that energy conservation, environmental/resource conservation and improving indoor environmental quality are major driving factors for green building development. Similarly, there is a lack of knowledge of green construction methods and regulations and lack of support from the government. This has been found as the major barrier in going towards green construction. We recommend policy directions towards this end and elaborate points of concern to the authorities.

Despite the provisions of the Land Use Act (LUA), cap L5 of 2004, to make land available for all stake holders, Federal Government has continuously found it difficult to access land in the states for her developmental projects. Does this influence successful implementation of her building construction projects in south-south Nigeria significantly? To what extent does the State where the project is domiciled influence successful project implementation? In order to provide answers to these questions a survey approach was used in three States (Akwa Ibom, Bayelsa and Cross River), randomly selected with two projects in each State. Structured questionnaire was used to elicit data from screened 179 respondents for the study. Two hypotheses were formulated to guide the research work. The dependent variables studied were land accessibility and successful project implementation while the State where the projects were domiciled was the independent variable. The analytical tools used included simple percentages, one-way Analysis of Variance (ANOVA) and Least Significant Difference (LSD) test. The hypotheses were tested at .05 level of significance. Findings revealed that State where the projects were domiciled had significant influence on the two dependent variables of land accessibility and successful project implementation and that Cross River State was significantly different from the other States on land accessibility but only on Akwa Ibom State on successful project implementation. The research proffers that for land to be easily accessible for Federal Government projects, Federal Government should enshrine in the Nigerian operating Land Policy the customs, traditions, and beliefs of the locals, take centre stage in all levels of land administration and educate her land administrative personnel in respect of government rights in land matters.

In Malaysian construction industry, Industrialised Building System (IBS) has been introduced to replace the traditional construction method. While the government has been making significant efforts to encourage the IBS adoption, the uptake of IBS in Malaysia construction projects remains low. This study seeks to identify the barriers to the uptake of IBS and to propose the strategies to enhance the implementation IBS in Malaysian housing construction process from the perspectives of consultants. Interviews were conducted with five selected experienced individuals who were working with consultants (civil and structure engineer and quantity surveyor). The results revealed that, lack of knowledge and insufficient skilled workers are the main factors that impede the IBS uptake in Malaysia. Meanwhile, the most strategy proposed by the interviewees is to increase the facilities and incentives in order to expand research and development in IBS.

Industrialization, urbanization, and economic growth are among the major causes of environmental degradation. These factors are closely related to the construction sector. To curb the issue, the government has initiated tax incentives to encourage developers embracing green technology. Developers who entitled to these tax incentives should enjoy a considerable amount of tax savings, which can be employed for capital reinvestment. Consequently, this study aims to determine whether firms that specifically involve with the construction of green buildings and have received the tax incentives are more likely to achieve relatively better financial performance, as a result of tax benefits gained from the government assistance. For the empirical analyses, secondary data was employed. A total of 138 firm-year observations from 2015 until 2017 used to measure the firm’s characteristic of board size, asset tangibility, deferred tax balances, and leverage against financial performance. The Theory of the Growth of the Firm was used to interpret the relationship between the financial characteristics and firm performance. We obtain evidence that indicates there is no significant difference in the financial performance between the GBI and non-GBI firms. The deferred tax balance, a proxy of the investment tax allowances granted by the Malaysian government to the GBI firms, is shown to be ineffective in improving the financial performances of these firms. The finding of this study suggests that any form of tax assistance from the government for the construction sector has not benefitted its recipients and requires remodeling.

For decades, reputation of the construction industry has been tainted by poor cost performance caused by project cost overrun. In addition, studies by scholars worldwide have also found cost overrun to be more serious in developing countries compared to the developed countries. Despite the numerous researches addressing the issue of cost overrun in the construction industry through the years, the issue remains. Acknowledging that maintaining good cost performance is a key factor of project success and that the issue has persisted for decades, this study aims to explore the distinction of cost overrun studies that has been conducted between developed nations and developing nations. In achieving this aim, a systematic literature review is performed by following the integrative steps of PSALSAR (Protocol, Search, Appraisal, Synthesis, Analysis and Report) and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) for screening and selecting the retrieved studies. The synthesis and screening of literatures have yielded with 152 articles which are then classified into their countries, developed countries (44) and developing countries (108). The results indicated a significant difference in the domain of research on cost overrun between the 2 nations. Despite the numerous studies on cost overrun in the developing nations compared to developed nations, the majority of the studies are not directed to any specific type construction while developed nations have moved forward to focus on more specific projects. The project with the highest attention in the developed nations is transport infrastructure construction projects, particularly rail infrastructure projects. The findings of this study have shown that there have been broad studies conducted on cost overrun in both developing nations and developed nations. However, there is a slight lacking in comprehensiveness of cost overrun studies in the developing nations, perhaps future studies on cost overrun in developing nations can be directed to more specific areas of construction projects such as those that have been performed by researchers of the developed nations.
