A Review - Factors Affecting on Time, Cost and Quality of Construction

Abstract: The primary goal of this study is to assess and explore time, cost, and quality management within the construction industry. The purpose of the study is to identify factors that impact time, cost, and quality management in construction projects. Quality stands out as a crucial aspect of all projects, and the success of construction projects hinges significantly on the performance of quality. However, accomplishing this objective is undeniably a challenging task. This study specifically investigates the factors that influence the control of cost and time in construction projects. The aim is to propose recommendations that can assist stakeholders in achieving enhanced cost and time performance in construction projects. The study acknowledges the intricate nature of balancing these key elements and strives to contribute valuable insights for improving overall project outcomes in the construction industry. This study is limited to the perspective of an appropriate sample of professionals in the construction industry. The data collection method involves the use of questionnaires and interviews, which will be subject to descriptive statistical analysis utilizing percentages, mean scores, and frequency of collected data. The primary factors influencing time, cost, and quality in a construction project were identified as planned and scheduled deficiencies, fraudulent methods, kickbacks, and the absence of clear evaluation standards. The research aims to scrutinize the factors that have both positive and adverse effects on construction projects. The study recommends that the construction team work diligently to ensure effective management of time, cost, and quality in construction projects. The objective of this study is to analyze how those involved in project teams perceive time, cost, and quality management on construction projects. Conclusions are drawn, and recommendations are made regarding time, cost, and quality management estimates for construction projects. In the construction industry, the concept of risk management is a less popular technique. There are three main stages in the systematic approach to risk management in the construction industry. A questionnaire, developed based on identified factors, was used to gather the opinions of construction experts. Quality is a critical aspect of any project, especially in construction. The success of construction projects is largely determined by the quality of work. Unfortunately, the construction industry is facing quality issues that result in ineffective and inefficient projects, leading to cost overruns, delays, and excessive rework. To address this issue, a research study was conducted to examine the factors that have positive and negative impacts on construction projects. A questionnaire was developed to gather feedback from construction experts, and statistical analysis tools such as chisquare and weighted mean method (WMM) were used to rank the significance of these factors. The definition of quality can vary depending on the perspective of those defining it. Some see it as meeting specific requirements, while others view it as delivering value for the price paid. For construction companies, quality is about satisfying customers and fulfilling their needs while staying within budget. Quality is an important factor in construction projects, as it can lead to cost overruns and delays. Quality control (QC) and quality assurance systems are established to meet specific requirements. In the construction industry, QC can be seen as achieving client satisfaction, managing costs, and allowing enough time to achieve the desired level of quality. An international standard organization (ISO) has developed a quality assurance system to improve quality and address quality-related issues. The ISO 9001 series has been created to apply to all types of organizations.

The Impact of Temporal Reflexivity on Time Performance in NPD Projects: A Mixed-Methods Study

Timely new product development (NPD) has always been a top priority in NPD projects. Despite realizing its importance, the empirical examination of specific factors that may improve NPD time performance has remained limited. This study investigated how temporal reflexivity influences NPD time performance based on the time, interaction, and performance (TIP) theory. Using a mixed-methods design, our research findings showed that temporal reflexivity significantly and positively influenced temporal coordination. Contrary to our hypothesis, the temporal coordination was insignificantly related to the NPD time performance. Furthermore, temporal leadership significantly and positively moderated the relationship between temporal reflexivity and temporal coordination.

A Review on Adoption of Bim in Reducing Construction Rework

In the construction industry, the aim of project control is to ensure that the projects are completed on time, within budget and achieving other project objectives .Rework is one of the most major problems in the construction industry. It has an impact on time, cost, quality, and practically every other project success factor. There is always a significant loss of resources, materials, investments, and workforce-time as a result of rework and poor use of resources and materials in the works. Rework may be reduced by designing and planning with full understanding of customers and stakeholders, good communication amongst project aspects, applying quality management systems, and utilizing Information Technology. Because of the worldwide expansion of IT and the widespread use of BIM ,which coordinates all of the software and parts of the construction--the appearance of mistakes and inconsistencies has been drastically reduced in recent years, allowing specialists to realize their full potential in doing projects. To the best of the author’s knowledge, this study is to use actual project data to measure the effects of BIM implementation on rework in construction projects. The study's findings enable practitioners to develop techniques to reduce rework with BIM implementation, enhance project cost and time performance, and increase project delivery efficiency

Client Peripheral Knowledge and Outsourcing Project Outcomes

ABSTRACT Client peripheral knowledge is the knowledge residing in the client organization regarding the specific technologies and methodologies needed to successfully complete an IT (information technology) project that has been outsourced by the client. Data is collected from 205 USA managers, who have overseen outsourced IT projects, to see if peripheral knowledge in their own client organization affected outsourced project processes and outcomes. The project processes examined are the degree of stability of requirements during the project, and the level of vendor activities to interface with the client. The project outcome is operationalized as client satisfaction, as well as project cost performance and time performance. We find client peripheral knowledge positively affects requirement stability and vendor activities to interface with the client; requirement stability in turn positively affects client satisfaction and time performance; and vendor activities positively affect client satisfaction, but levy a penalty on the cost performance and time performance.

Appraisal of Fixed-Sum Contracts on the Time Preference of Tetfund Sponsored Building Projects in Public Universities in South East Nigeria

The construction industry faces significant delays, particularly in developing countries like Nigeria. Tertiary institutions, including universities and polytechnics, are often funded by various entities. A study evaluating the impact of fixed-sum building contracts on the time performance of TETFund-sponsored projects in Enugu State found that none of the specified project durations were completed within the stipulated time. This violation of TETFund guidelines allowed for nonchalance by all stakeholders involved in the projects. The study recommends that stakeholders in the building team take responsibility for ensuring projects are delivered within the specified duration, as previous intervention projects were not completed. Keywords: Appraisal, Fixed-Sum, Contracts, Building Projects and Public Universities

Comparing time and cost performance of DBB and DB public construction projects in Kuwait

Kuwait is an enormous construction site as many vital public projects are under construction or in preparatory stages to achieve the vision of a New Kuwait by 2035. However, the new Public Tenders Law No. 49 of 2016 authorized the sole operation of the Design-Bid-Build (DBB) method as the delivery system method, preventing the employment of Design-Build (DB). Hence, this research undertook a comparative analysis of cost and time performance of DBB and DB public construction projects in Kuwait for the first time, marking the originality of this study. Moreover, 160 projects were collected from four government entities. Then, the total collected projects were categorized based on contract types and project sizes depending on contract cost. This research has recognized that DB has superior performance compared to DBB regarding cost growth for all collected projects, both contract types, projects of less than 300,000 KD, and projects between 300,000 and 12 million KD. No statistically significant differences between DBB and DB projects regarding schedule growth were found for all collected projects, both contract types and project sizes. Furthermore, the findings indicated that the DBB projects’ construction intensity was faster than that of DB projects with a value between 300,00 KD and 12 million KD. For projects that had a value of more than 12 million KD, the DB projects’ construction intensity was faster than that of DBB projects. Hence, it is concluded that the issue is not with the DB delivery systems themselves, but rather with the deployment of these systems.

The impacts of 5D-Building Information Modeling on construction's Time and cost performance

The construction sector is essential to a country's economic growth and development. This is why the construction of building projects is one of the most pressing concerns for the Indonesian government. The industrial sector has become increasingly dynamic and responsive to the challenges of building projects due to technological advancements. One example is the Building Information Modelling (BIM) 5D, an emerging technology integrating project implementation time and costs into a 3D model. Therefore, this study aims to investigate the success factors of BIM 5D implementation on the time and cost performance of high-rise building construction projects at Campus-II UIN Sunan Ampel Surabaya. This was achieved through a quantitative research method using a questionnaire completed by 62 respondents: the project manager, site manager, engineering head, and site engineer. Moreover, descriptive statistics were utilized to examine the frequency distribution of concentration measures and data distribution on sample characteristics and variables. The findings showed that the factors of tender document, human resources, BIM software, planning process and production process simultaneously positively affected the construction project's cost and time performance.

CRITICAL SUCCESS FACTORS FOR MODULAR CONSTRUCTION ON HIGH-RISE RESIDENTIAL BUILDINGS BASED RISK MANAGEABILITY TO INCREASE PROJECT TIME PERFORMANCE

International Construction Costs published in Comparison 2020 continued to increase as an impact of the Covid-19 pandemic, The modular system is considered able to answer the problems of increasing costs. Although modular construction has been widely applied to low-rise buildings, application in high-rise buildings remains limited, less than 1% worldwide. The need for residential high-rise building applying modular construction in Indonesia becomes important. The interdependence between parties in modular projects is greater than in conventional methods. Unavailability of design guidelines hinders the construction industry in implementing modular technology. The purpose of this study is to analyze the critical success factors for modular construction of residential high-rise buildings applying risk-based management to improve project time performance. Forty-one Indicators were drawn from literature reviews and specialist interviews to conduct a sustainability evaluation. The survey was submitted to case project developers, designers, supervisors, and contractors in Indonesia, thereafter statistically analyzed using SPSS and risk management analysis with three stages: risk sources, risk drivers and risk causes. Critical success factors for drawing approvals have a considerable influence on modular construction among 15 other factors, followed by supply chain and design standardization. It is necessary to mitigate these risks to improve project time performance.

Assessment of Cost and Time Performance of Tertiary Educational Trust Fund (TETFund) Construction Project in South-West Nigeria

Funds have been allocated to TETFund annually for infrastructural development in Nigeria to address decays of educational facilities and create an enabling environment for teaching and learning. This study evaluates time and cost performance of public building construction projects funded by TETFund in South-West Nigeria. The study adopted questionnaire survey by self-administering two hundred and fifty (250) questionnaires to project clients, consultants and contractors engaged in TETFund projects in South-West Nigeria. One hundred and eighty-six 186 (74.4%) of the questionnaires were retrieved from the respondents and were used in the study. Also, record of project cost and duration were purposively obtained from two hundred and fifty-four (254) TETFund sponsored projects from Institutions in South-West Nigeria. Mean Score (MS) was used to rank the various items and components while regression analysis was used to forecast future project cost and time. The top three factors that influence cost and time based on the perceptions of the respondents are client satisfaction with the project (MS= 3.86), construction time predictability (MS= 3.85) and construction cost predictability (MS= 3.83). From the TETFund project records analysed, a total sum of ₦10,856,167,497.14 was spent on TETFund building construction projects in South-West Nigeria from 2003-2013 with a contingency sum of ₦163,248,265.44. The average percentage cost overrun for TETFund projects was 1.62% and that of time overrun was 112.23%. Regression analysis of the predicted project time and cost was significant and can be used to forecast time and cost of future TETFund projects. Therefore, it was recommended that accurate cost estimate, adequate project planning and good specification should be carried out by project stakeholders before contracts are awarded to enhance construction project performance. Also, the developed regression model of estimated project cost and time can be used to predict cost and time of future construction projects.

Influence of digitalisation adoption level on construction project delivery in Nigeria

PurposeThe rate of project failure across the globe seems to reinforce poor performance as a norm. However, engagement with construction digitalisation (CD) represents a departure point for improving project performance. Amidst researchers' recent empirical engagement with CD, the knowledge of the relationship model between CD and project delivery (PD) is abysmal. As a result, developing a business case for CD in developing countries has been slow due to the dearth of empirical evidence. This paper aims to investigate the influence of digitalisation on project performance.Design/methodology/approachAnchored on cross-sectional survey research design using a questionnaire survey in which a total of 183 copies of structured questionnaires were randomly distributed to medium- and large-sized construction firms operating in Abuja, Nigeria's federal capital. A total of 126 valid responses were received giving an overall response rate of 68.8%. The responses were analysed using mean item score, principal component analysis and multiple linear regression.FindingsFindings from the regression analysis reveal that digitalisation has varying levels of impact on PP measured using quality, time and cost. The relationship model with time performance is weak (r = 0.526, r2 = 0.277); on cost performance, the significant model is also weak (r = 0.502, r2 = 0.252) and moderate on quality (r = 0.663, r2 = 0.439). CD influences project cost, time and quality performance despite the weak relationship model. The results indicate that the most effective benchmark of CD is quality performance.Originality/valueThis study established the relationship between digitalisation and construction PD within the construction industry context, an area lacking research attention in emerging economies. This study is the first study in emerging economies that established the influence of digitalisation on construction PD statistically.

Integrating machine learning and network analytics to model project cost, time and quality performance

This study aims to connect project management, network science and machine learning in an accessible overview applied to a real original dataset. Based on an initial literature review of applicable project performance measures and attributes, relevant project data were collected through an online survey. The information was split into three categories, including the basic project measures (five attributes), project stakeholder network measures (seven attributes), and project complexity measures (seven attributes). In total, 70 responses were collected, and five machine learning approaches (i.e. support vector machine, logistic regression, k-nearest neighbour, random forest and extreme gradient boosting) were applied to model the relationships between project attributes, networks and the Iron Triangle of project cost, time and quality. The results confirm the expected trends affecting project performance and provide an example for the discussion of the applicability of integrated machine learning and network analytics approaches to modelling project performance. The article demonstrates in an accessible way a real case of integration of machine learning, network science and project management and suggests avenues for further research and applications in practice.
