In the countries like India where one has to still handle a unique blend of operational diversities like human operated traditional construction practices and modern construction technologies, in all construction projects that are highly vulnerable to socio-economic, political, technical and business risks. The involvement of the people with diverse educational, technical, economical and experience backgrounds is an unavoidable fact of the construction industry in India and hence the human factors are going to play a key role in the project to be more prone to risks as well as to mitigate the likely projects risks. Due to lack of robust risk management system, many prestigious construction projects in India have suffered failures and have impacted the country’s GDP and growth because of the gigantic share of the construction industry in the country’s economy. Hence, the risk management in the construction industry has become the subject of concern for the industry practitioners and so the analysis of operational difficulties for the identification and management of construction related risks to minimize the cost overruns, quality deviations and uncertain delays, is remained to be the main objective of the research by the domain experts and engineers for so long. In this paper, an attempt has been made to review all such papers with a specific aim to identify and analyze the human factors that, are highly acknowledged by experts in their works and, can influence / impact the project parameters namely cost, time and quality and validate the results by tracking a real time construction project to draw conclusions.

The Impact

Construction is questionably a main part in relative to comprehensive development . It plays an important part in the role in the economy as and in people’s survives over influencing and preserving the environment of the city-region’s constructed, and it is a rising sector. To provide an efficient performance and more development of the economic, there is emphases on optimizing the employees contribution to the goals and areas of the governments. The training significance as a management central part has long been documented by principal writers.This paper aim to find the impact of training in the construction industry and how the training is been underestimate lead in increase the cost by using the simulation technique system dynamic. The research methodology include designing of questionnaire that consist of three items , the first item include , general Training (Training Program), evaluation of on-the-job training and evaluation of training after establishing work and the second part include building the model using system dynamic to show the effect of training on the cost of construction. the results the authors made the following conclusions .The absence of training program has very strong effect as the absence of such program is caused by the finance absence , this is common problem with Iraqi construction industry. The most environment of the Iraqi industry is the absence of the finance from both owner and contractor as they ignore this part and consider unnecessary expenses and this will lead to unqualified engineering or worker in the wrong job .The absence of management mean that , usually the contractor and his staff are working without the supervise or represented from the owner side , which some time mean unskilled workers may be hired which lead to delay of the work and cost overruns .

Cost overruns vary evidently almost in every construction project, but their magnitude from project to project. The cost overruns have hit down the economy and the reputation of many Construction Company and hit down the economy and the reputation of many construction companies around the world. Many project management tools are designed to manage the project's budget. However, cost management is still considered poor, as there are many cost overruns in the construction industry. Thus, this work is aimed at identifying and clustering potential factors of the excess cost of construction projects in accordance with their original groups using a thematic approach. Basically, through a literature review, all the potential factors that could cause cost overruns were carefully analyzed before they were grouped into seven (7) groups of underlying factors, namely: project, contract, client, contractor consultant, workforce and external. Each potential factor was clearly explained with some examples based on Malaysian case studies to illustrate the cost overruns scenario. These findings may help in the future to focus on how to mitigate critical potential cost-overs to reduce or overcome its impact on all involved stakeholders.

The quest for delivering successful construction projects has urged South African small and medium enterprises (SMEs) to adopt risk management in their projects. However, it has been evinced that SMEs projects in South Africa especially in the Gauteng province have encountered poor performances. Thus, this article determines core risk management factors influencing project outcome of SMEs. A deductive approach was embraced using a questionnaire. The data were collected from 181 conveniently sampled respondents in Gauteng, graded from Grade 1 to 6 of the CIDB (Construction Industry Development Board) grading system. The Statistical Package for the Social Science (SPSS) version 23 was used to analyse the data by computing exploratory factor analysis and multiple regression analysis. It was revealed that SMEs performance outcome is influenced by eight risk management factors. The influential factors are organisational environment, defining project objectives, resource requirements, risk measurement, risk identification, risk assessment, risk response and action planning and monitoring, review and continuous improvement. The risk management factors established in this article are reliable and valid in projects undertaken by SMEs in the South African construction industry and the findings can serve as a guideline for contractors to achieve success in this context. The study may be repeated in other countries globally, however, it cannot be generalised due to the restrictions pertaining to the geographical area.

Construction practitioners recognise that rework is undesirable due to the detrimental effects. While rework literature has examined rework causation factors in construction projects, the problem continues to plague the industry resulting in poor delivery performance. To better understand this phenomenon and given the scarcity of Malaysian-based rework study, a questionnaire survey involving 130 Malaysian construction practitioners (consultants, contractors and clients) were undertaken to obtain feedback about nature, implications, causes and solutions for rework. Data were analysed using descriptive statistical techniques to prioritise the variables studied. From the analyses, rework is a causal factor for delays and cost overruns, higher wastage and productivity inhibitor. The findings revealed the leading causes of rework are poor quality management, improper planning, lack of communication, design changes and poor subcontractor management. Some practical rework minimisation approaches are also suggested to better manage and prevent rework towards enhanced project performance.

Construction industry is an important industry and remains so with the continuation of the development process especially in the developing countries. On the other it is very risk and hazard. As industry when compared to other industries financial losses and bodily injury and death, and resulting human, social impacts are more in the case of construction.  Mishaps also contain significant costs that are not insurable. Financial deliberations contains direct costs like medical reimbursement and  hidden costs includes loss of competence by breaking up crew, cost to train fresh or changed employee, damage to equipment and tools, cost experienced by delays. Many researchers have been suggested risk management techniques to minimize the losses in the industry and very few companies may be implemented the suggestions.  The goal of this study is to recognize and rank risks in construction projects. This study proposes the hierarchical dependencies between the criteria. The variations and factors have been investigated via questionnaire and is an element of an on-going research into the application of risk management in major projects. To know the performance and applicable of proposed model set of data collected from different industries by using the informal approaches such as intuition and experiences the study is conducted to prioritize and manage risks.

This paper presents findings of an investigation into benefits of using Building Information Modelling (BIM) in construction projects. The research methodology includes a review of BIM development and achievement in construction industry, questionnaire survey, interview, and content analysis of secondary data. Data was collected and analyzed to identify the various benefits reflected from BIM implementation in addressing common problems experienced by the construction industry. The review and survey results indicate that a high frequency of occurrence of time and cost overruns occur in construction projects. Contributing factors were mainly rework, poor planning, documents delivery and approval, constructability issues, resources and weather condition. While some of the factors were unpreventable, BIM could be used as a tool to eliminate problems causing time and cost overruns. Various project benefits have been reflected through the content analysis of project case studies. It was found that time was the most positively influenced by the use of BIM followed by coordination, procurement, communication, cost and change of scope of the project, and lastly, risk.

The construction project is a complex sector which characterized with low productivity, cost and time overruns and conflicts. The major challenges in construction project risk assessment which may attributed to knowledge requirements for determining the level of uncertainty and development of complex models to predict . Portfolio theory and capital market theory stipulate that risk consists of two types, First, systematic risk, which cannot be controlled, emanates from external factors such as acts of God, natural disasters, market risk, interest-rate risk, and purchasing-power risk. Second, unsystematic risk, which can be controlled, relates to organization-specific factors such as business risk and financial risk (Fischer and Jordan 1996).) . To identifies the risk factors that influence the cost-effective management, operation, and maintenance of construction project, as well as how and when in the project life cycle the identified risk factors impact to the associated costs . The identification and design of risk is the first step of risk management. It contain the recognition of potential risk event conditions in a project and the clarification of risk responsibilities. A total of 50 risk factors on construction for stake holders (client , contractor ,consultant ) share projects were identified after conducting an extensive literature survey. A questionnaire survey was conducted from 60 project managers(20 from each category) in all three proficiencies with background experience in buildings ,road and bridges with minimum 15 years experience , to identify the most significant risk factors impact in construction projects . Interviews were conducted face to face, ensuring a 100 percent response rate. The questionnaire was amended by incorporating feedback of the experts to suit the local environments of the construction industry. The weight or rate of each risk factor gained by using a five-point Liker scale from a consolidated conceptual framework of all 50 risk factors identified from the deep literature work . The main aim of these research is to identify ,categorize and ranking common risks, exert management techniques to address those risks , effective risk management and risk status in the construction industry and to help stakeholders to take stock of their ongoing and future projects, with a focus on important risks, their management techniques and barriers to effective implementation of risk management systems.

The Cost

As a project control technique concept that provides a quantitative measure of schedule and cost information, the earned value (EV) model can evaluate work progress by identifying the potential delay and the cost overruns in a project, which is useful for controlling projects. The construction industry in Korea does not put this concept into practice, however, because it is poorly understood and because the construction practices in Korea are different from those in other industrialized countries. Most important is the fact that almost all the construction projects in Korea are controlled in accordance with the budget breakdown structure (BBS), which is less detailed than the cost breakdown structure (CBS), while those in the USA are managed through schedule control on the basis of the work breakdown structure (WBS). This is because most of the construction projects in Korea are generally contracted at a fixed price. This being the case, once the contract is awarded, the clients are no longer concerned with the cost of the project. This current construction practice based on the BBS rather than on the WBS has brought forth a limitation in terms of the use of the existing EV model in the domestic market. In this study, the EV model, which is suitable for the domestic market, is demonstrated. An integrated model of the WBS and CBS is then developed based on the modified work-packaging model. Finally, the developed model is integrated into the project management system (PMS) to verify its suitability and efficiency.

Variation order (VO) is one of the main issues faced by the construction industry in Jordan. Many researchers had investigated on the causes of VO and proposed procedures to minimize and control this issue; however, the VO is affecting the construction industry badly even at moment. Building Information Modeling (BIM) is a powerful management system that can make a significant difference in the project costs. However, BIM has not been examined as a tool to minimize the VO in Jordan. The main target of this study is to utilize BIM applications in reducing the effect of VO on the governmental projects in Jordan. In order to achieve this target, the researcher has designed a questionnaire to gather data related to VO causes and the BIM capability to solve this problem. The data collected from the questionnaires were analyzed statistically. The result from the analysis found that the consultant initiated the highest VO of 50% followed by the clients and the contractors of 20% and 10% unforeseen variation respectively. Moreover, it is found that BIM Design Applications, Facility Operations Simulation, Exploration Design Scenarios, BIM Design Detection and BIM Quantity Take-off and Cost Estimation were significantly capable of minimizing VO. The results show positive relationship with the application of BIM in minimizing VO in the construction industry in Jordan. © 2018. JASET, International Scholars and Researchers Association
