The Type and Function of Floor Area Ratio Relaxation in South Korea

We live in a world where floor area ratio(“FAR”) dominate. Floor area ratio is expressed as a percentage and is regarded as technical, but the difference in that percentage determines the price of the land, the height and shape of the building that can be built, and the success or failure of various construction projects. However, it is difficult for us to grasp the meaning of relaxing floor area ratio to 400%, and how far it can be relaxed. Large cities with limited land area have reached the limits of their horizontal expansion. High-rise buildings have become a low-cost solution to housing problems by vertically expanding scarce land. The method of solving housing problems through high-rise buildings has been used worldwide and is welcomed as a way to accommodate large-scale populations at low cost. The policy of easing floor area ratio in South Korea played an important role in solving housing problems. The government have been utilizing the policy of relaxing FAR to supply high-quality housing to the metropolitan area, stimulate the construction economy, and improve outdated urban infrastructure. Relaxing FAR is widely used in Korea because the interests of the major players in the dynamics surrounding FAR are consistent. Ordinary people without a house have the opportunity to obtain a new house in the space created through an increase in FAR. In addition, landowners can benefit from increase land prices by increasing their FAR. For business operators in reconstruction or redevelopment, FAR increase works as a factor that determines the profitability of the project. While the government uses FAR as a tool to realize a comfortable residential space, it is possible to balanced development and sustainable growth. Local governments can revive the economy in their jurisdiction by raising FAR and securing the necessary facilities, such as expanding infrastructure. This paper aims to examine the history of laws and regulations on how the relaxation of FAR has been introduced and developed in our legal system. The types of FAR relaxation were classified into four types; under the Building Act and the Urban Planning Act, district unit planning type, Zoning type, and other legislative type. The function of FAR relaxation for each type is to provide a clue for inferring the legal nature of FAR and predicting the future of FAR. This paper makes a contribution to understanding urban planning by providing a new case study of relaxing FAR focused in South Korea.

Comparing data mining methods for predicting cost construction projects: A case study of cost management datasets from Thailand

This research examines three data mining approaches employing cost management datasets from 391 Thai contractor companies to investigate the predictive modeling of construction project failure with nine parameters. Artificial neural networks, naive bayes, and decision trees with attribute selection are some of the algorithms that were explored. In comparison to artificial neural network’s (91.33%) and naive bays’ (70.01%) accuracy rates, the decision trees with attribute selection demonstrated greater classification efficiency, registering an accuracy of 98.14%. Finally, the nine parameters include: 1) planning according to the current situation; 2) the company’s cost management strategy; 3) control and coordination from employees at different levels of the organization to survive on the basis of various uncertainties; 4) the importance of labor management factors; 5) the general status of the company, which has a significant effect on the project success; 6) the cost of procurement of the field office location; 7) the operational constraints and long-term safe work procedures; 8) the implementation of the construction system system piece by piece, using prefabricated parts; 9) dealing with the COVID-19 crisis, which is crucial for preventing project failure. The results show how advanced data mining approaches can improve cost estimation and prevent project failure, as well as how computational methods can enhance sustainability in the building industry. Although the results are encouraging, they also highlight issues including data asymmetry and the potential for overfitting in the decision tree model, necessitating careful consideration.

Complexity in Construction Projects: A Literature Review

Improper understanding of complexity can be a leading factor in the failure of construction projects. This study aims to provide a better understanding of the complexity of construction projects. For this purpose, this study uses the systematic literature review (SLR) approach to review the related literature and propose a definition for complexity and the criteria that affect the degree of complexity in construction. The results of analyzing 49 studies from the literature showed that, generally, complexity is understood in three ways: the meaning of the word “complexity”, system and organizational complexity, and project complexity. Within these three types of definitions, it was found that “interdependency” and “multiple parts/parties” are the most frequently used keywords. The results also showed that another look at the current lingual definition of complexity is needed. Regarding the criteria, the results showed that the “number of stakeholders”, “scope and project objectives”, and “management structure” are the most important criteria to assess construction project complexity. Accordingly, this study provides a set of recommendations and strategies to help manage complexity in construction projects.

The Need to Educate Foreign Workers Based on the Performance Factor in a Construction Project, Especially in a Highly Populated Area in Johor, Malaysia

The problem of foreign worker is currently increasing due to many factors and has necessitated a comprehensive study to identify the critical factor that leads to the failure of construction projects. Therefore, the objective of this study is to investigate the factors affecting the performance of foreign labour so that the foreign worker can be trained and educated. Methodologically, a total of 68 questionnaires were distributed to respondents at construction sites in four districts of Johor Bahru, Kota Tinggi, Kulai and Pontian in Johor. The selected site was based on the study location, population, design criteria, sample size, sampling frame, sampling method and data collection method. The survey consisted of two sections, Sections A and B. Section A deals with the demographic profile of the respondents. Section B deals with the main factors affecting performance. The data was then analysed using descriptive analysis to determine the mean of the responses. The results show that inadequate health and safety awareness at the worksite is the most important factor affecting the performance of foreign workers. The results also show that the most negative influence of foreign workers is on the construction project. Therefore, the company needs to spend more resources on training the foreign workers. To overcome the problems, the company needs to set and pursue goals to improve the skills of the worker force. This factor is overcome through various strategies such as training foreign labours, monitoring their performance, communicating regularly with the workers and pursuing goals to improve the skills of the workers. The findings of this study can therefore be used to train and educate the foreign worker to perform better in construction projects, especially in heavily populated areas.

Developing Adaptive Multi Dimension Road Construction Management Using EDAS Technique

Adaptive road construction project Management is considered a major challenge in economic development issues. This research looks intothe many variables that can have an impact on building projects. Unfortunately, infrastructure projects in Iraq have slowed the country's progress, so effective methods of project management using actual databases are urgently needed. This research established a centralized data bank with a collection of specialized maps depicting the status of infrastructure projects in Iraq, and it also produced an advanced administrative system via effective success and failure elements that allow administration of projects. Implementing adaptive features during road construction projects is the primary problem of this study. There were two stages to the study methodology; the first was the Delphi technique, which was used to determine the first set of influential elements. The EDAS method was employed in the second approach, and it provided the most useful information regarding the aspects that could affect road construction projects positively or negatively. According to the findings, there were a number of effective factors that could lead to the failure of road construction projects. These included insufficient site security, poor site management and supervision, ineffective field management, inexperienced equipment operators, and insufficient consultant experience. The findings may be helpful for the policy makers and the practitioners in future.

Construction Project Failure and Abandonment in Kaduna State, Nigeria: An Analysis of the Causes Using the Relative Importance Index

The construction industry serves as one of the key players of a nation's economic growth, considering its role in infrastructural development, revenue generation, provision of jobs and shelter for the masses, enriching the esthetical view and influencing the growth of other key sectors of a nation. In this research, a study was carried out on the causes of construction project failures and abandonment in Kaduna state, Nigeria. The study’s objective was to identify the possible causes of failure and abandonment of construction projects and evaluate the identified causes in their order of importance. To achieve this, a quantitative research approach using questionnaires as an instrument for data collection in Kaduna state was adopted, using a total of One Hundred (100) survey-questionnaires distributed among professionals and workers in the construction industry. Analysis of the data acquired from the returned questionnaires was done using SPSS v26 and MS Excel 2016 to obtain the descriptive statistics and the Relative Importance Index (RII).

The Spearman rho correlation showed some significant but low relationship among the variables, while the Kruskal-Wallis test indicated the same distribution of all the variables among the construction professionals. The research also revealed that although insecurity was a burning issue for the industry especially in the study area, its ranking showed that it was not considered a significant factor in relation to the other factors.

Risk Analysis and Research for Construction Projects

As the population grows and the demand for public infrastructure increases, more and more construction projects are being carried out. In order to avoid the failure of construction projects due to their high level of complexity, risk anticipation and risk response can be made through the study of project risks, which can greatly improve the success of construction projects. The investment and time spent on a construction project are huge and if the project fails or is delayed, there will be serious consequences. This is why construction project risk management is so important for construction projects. Therefore, this paper analyses the risks of construction projects. It finds that construction project risks can be classified as internal and external risks and suggests improvements to the existing three-step project risk management process Identify-Assess-Respond, adding a project risk review. This paper enriches the study of risk classification and management processes for construction projects and proposes risk management process measures that have implications for future construction projects to deal with risks more efficiently.

An Analysis of How the Construction Business in Ethiopia Is Affected by the Rising Cost of Building Materials

The construction industry differs significantly from other economic sectors due to a variety of distinctive features. Construction projects fail with a disproportionately high frequency in Ethiopia's construction industry today because it is fragmented and highly subject to political and economic cycles. However, due to the numerous risks inherent in how the sector functions, phrases like project business failure, collapse, and bankruptcy frequently used in Ethiopian construction. Assessing existing issues with Ethiopian construction project failure was the goal of this study. According to the study's findings, the main causes of current construction project failure are delays in clients' (donors') debt collections, border closures, heavy dependence on bank loans and payment of high interest on these loans, lack of capital, absence of industry regulations on building materials costs due to high neglect in free market and lack of experience in contract management. Finally, realities of the focus group showed that the construction project failure is valid and it represent a step forward in the way of construction industry development in Ethiopia. The results of the research also recommended to that there be an urgent need for an independent and responsible body to take the lead of the adoption and the application of the ethical code and more efforts need to done to help construction sectors to understand and realize the importance and role of ethics professional in construction industry. Education and mandatory training programs can conducted for stakeholders about the content of the market inflation and rising Cost of Building Materials to control. Media's role and research development also is very important. Based on these findings, approvals to all stakeholders are obey for National Trade Industry Regulations that currently work in Ethiopia construction industry.

An Exploration on The Construction Management Failures in Ongoing Projects of The Kabul City

The construction industry is known for its chronic problems of fragmentation, low productivity, time and cost overruns, poor safety, inferior working conditions, and insufficient quality which ultimately led to project failure and poor construction images. A project becomes a failure when it does not deliver what was required within the agreed-upon budget and time. The majority of projects are temporary efforts to create value through a unique product, service, or result. Almost all projects have a beginning and an end. They have a team, a budget, a schedule, and a set of expectations the team needs to meet. Each project is unique and differs from routine operations and the ongoing activities of the organization. The project of an organization reaches a conclusion once the goal is achieved. The purpose of construction project management is to control a project's time delivery, cost, and quality, and it requires professional management to decrease failure factors. This study covers the construction project management failures and their causes during and after the construction and focuses most on the critical factors that cause the failure of construction projects in Kabul city. Two types of methodologies have been used which will allow the researchers to dive deep and get more information regarding flaws and failure causes, especially with the help of root cause analysis that has made the research more effective. Cost control, scheduling, procurement, and risk assessment have been reported as significant issues that must be addressed in the complicated discipline of construction project management.

Examining the success drivers and barriers of modular building projects using qualitative comparative analysis

Compared to traditional construction methods, it is expected that modularization can achieve a faster, cheaper and more sustainable delivery and, as a result, should have a higher chance of project success. However, it is not unusual that modular projects fail to achieve the project objectives and stakeholders’ expectations. The failure of modular construction projects makes researchers and industry practitioners wonder whether the causal configurations for modular project success and failure are different from other types of construction projects. This study contributes to the body of knowledge by exploring the combinatorial impact of success drivers and barriers on project outcomes using qualitative comparative analysis, with a specific focus on modularization practices in the building sector. The data matrix, which summarises project information of 31 cases, is imported into analysis software, fsQCA 3.0, to test the multiple conjunctural causations for modular building project success and failure. The analysis results confirm that the success drivers and barriers interactively and collectively influence project outcomes of modular buildings. The most commonly involved success drivers and barriers are discussed in detail. This research will serve as a valuable reference for building sector practitioners and facilitate the effort to improve the success rate of modular building projects.

Developing models to predicting the effect of crises on construction projects using MLR technique

Most construction projects are exposed to multiple external and internal problems and obstacles that lead to a crisis within the construction project, which may lead to the failure of the construction project. It is also a source of concern for owners, stakeholders, and contractors alike due to its difficulty. As a result, a new approach to dealing with crises prior to their occurrence is required. Accurate construction project prediction concerns at the early stages of a construction project are critical factors in the success of a project. This study develops anticipatory models for construction project crises by identifying and categorizing the major different variables that affect construction project objectives and indicate time overrun, cost overrun, and poor quality for construction projects before crises occur. The most influential factors on the failure of construction projects in Iraq were identified in this study; some of these factors affect project implementation time, others affect project cost, and the remaining factors affect construction project quality. The independent variables measurement model is designed to collect accurate raw data from the site. This model is based on 53 data samples collected from various multi-story building projects, which were used to construct and test the model. From MLR multiple linear regression results, three equations were derived from calculating the percentage of overrun (time, cost and quality) because of the construction project being affected by crises. Found that the correlation coefficient of the above models is (99.8%, 98.6%, 96.5%), respectively.

Microscopical Resource Allocation for Large-Scale Apartment Foundation Work Using Queuing Systems

Resource management can determine the success or failure of construction projects and is indispensable in frame construction owing to the numerous resources allocated. Various research methodologies have been proposed for successful resource management, but they have not been conducted from a microscopic point of view such as activity. This paper quantitatively analyzes the impact of a concrete pouring team allocation on the project from a microscopic point of view, and proposes a framework for allocating the optimal team. Firstly, a time-dependent queueing model-based method is proposed for evaluating the influence of the pouring team for foundation concrete pouring. Data from large-scale apartment project cases in South Korea were used to verify this framework. Using time and cost metrics, the impact of the pouring team on the project was quantitatively analyzed. Finally, comparative analysis was performed to compare the concrete pouring team costs, including the average server cost and waiting cost before and after optimization. The proposed method reduced the total pouring team cost by 26.27% (KRW 35,547,600); it can help determine the optimal number of concrete pouring teams required for frame construction and improve the performance of construction projects from the process planning stage itself, by ensuring appropriate resource planning. However, since a single case was used, it is necessary to apply the proposed framework to actual construction after analyzing various cases in future studies.

Geotechnical Characteristics of Benin Formation, Owerri Imo State, Nigeria

A good road network consists of a constant stretch of asphalt laid down for a smooth ride. The spot in the smooth ride on the pavement is commonly referred to as "pavement failure." Soil type, load bearing capacity of materials, zone of vulnerability, resistance to permeation, compressibility, shrinkage limit, and other details are frequently required in order to construct a very good and solid foundation for the planned bridge site. In Nigeria, numerous factors contribute to the failure of road construction projects. They are primarily insufficient research on subgrade and other pavement materials (sub-base and base courses) prior to the start of road projects; flawed engineering, including a poor drainage system and supervision throughout road construction; and shoddy workmanship that was superimposed with asphaltic concrete to improve strength. Within the Niger Delta basin, the study area is located between latitude 5.485°N and longitude 7.035°E. The Benin Formation underpins the study area. It is composed primarily of friable sands, conglomerates, very coarse sandstone, and isolated gravel units, as well as intercalation of Pliocene to Miocene shale/clay lenses. Natural Moisture Content (NMC), Linear Shrinkage (LS), Particle Size Distribution, and California Bearing Ratio were among the laboratory tests performed on samples collected at failed and stable sections of some selected road segments (CBR). When compared to the stable sections, the NMC along the failed sections was on the high side (ranging from 13.11 percent to 26.89 percent) (ranging from 11.11 percent to 16.40 percent). The majority of the tested soils passed the 0.075mm sieve with a percentage greater than the Federal Ministry of Works and Housing's maximum of 35% for subgrade materials. The maximum dry density (MDD) for the samples at failed and stable sections was 1550 kg/m3 to 1860 kg/m3; 1650 kg/m3 to 1980 kg/m3; and the Optimum Moisture Content (OMC) was 8.30% to 20.30%. The soaked CBR values ranged from 2 to 17 percent, while the unsoaked values ranged from 4 to 25 percent.

Prospects for the adoption of Agile Project Management techniques in Nigerian construction industry


 
 
 Persistent failure of construction projects to meet clients’ objectives has compelled a review of the extant systems for project delivery. This study assessed the prospect of adopting Agile Project Management (APM) for construction project delivery in Lagos State. To achieve this, the study examined the level of awareness of APM among construction stakeholders and developed a SWOT model for the adoption of APM technique for construction projects. The research adopted survey method using questionnaire. The study sample involved 196 construction stakeholders. Data obtained were analysed using Mean Score and Fussy Set Theory. The result showed that stakeholders’ level of awareness about the individual methodologies of APM is high. There are also weighty strengths, weaknesses, opportunities and threats in the adoption of APM in construction project delivery. The level of awareness among stakeholders portrays high prospects for APM adoption. However, there is need to embed trust, cooperation and improved team performance.
 
 

The Project Performance Evaluation of PLBN Project Using Earned Value Management Method

Process of monitoring and controlling projects requires data evaluation activities in the order to find out whether the project is in accordance with the plan to avoid an incompatibility between the planning and the actual time. The failure of construction project almost reached the figure of 20% - 40% which occurred in the project monitoring and controlling process. The purpose of this research is analysis project performance with earned value management method at PLBN Project. This research was carried out by several stages: data collection, data processing and analysis. From the results of the performance index analysis show that the project’s performance on the construction project is still not good. At week 16 the CPI and SPI values are 0.94 and 0.85. Both values can be interpreted that the costs incurred are greater than planning and the implementation time is longer than planning. The result of EAC is Rp. 2.423.695.294 with an estimated completion time is 21 weeks which indicates that there is an additional 3 weeks of completion.

Assessing the Risk Level of the Challenges Faced In Construction Projects

The failure of construction projects could be attributed to several challenges that emerged during the construction process. Nine major challenges were uncovered from the literature: resource allocation, time, cost, quality, safety, project complexity, changes, uncertainties, and communication. A survey was carried out among professionals having a minimum of 10 years of experience in the construction industry to identify the occurrence and severity of these challenges. A total of 117 responses were analyzed and plotted on a risk matrix. The mean values indicated that time, cost, and quality are the top three challenges faced in construction projects, while the risk matrix revealed that all challenges are high-risk challenges. Thus, the professionals should consider suitable measures to address these challenges for improving a project’s performance.

The Impact of Risk Management Practices on the Performance of Construction Projects

Construction performance and risk management has been widely discussed in the literature from various perspectives. The main objective of performing risk management in construction industry is to ensure timely delivery of good construction within sepecific budget. However, the failure of many construction projects in meeting deadlines, cost and quality targets is continuously on the rise and there are signs of accentuating year after year suffering significant financial losses of construciton works in Oman. Therefore, there is a need for empirical evidences to explain the relationship between risk management and project performance. This study applied quantitative methods to examine this relationship. Construciton companies from grade excellent to grade second in Oman haven included in the survey. The result revealed that practicing risk managementimprove the performance of construciton project significantly. Based on this result it is essential to hire qualified project managers who has sufficient knowledge in risk managmeent and its main activities.

A critical analysis of unethical professional practices in the construction industry in Southeast Nigeria

Economic transformation and the provision of basic infrastructure to engender growth and development in any nation is vested in the construction industry hence the massive investment of the government in this sector. However, the expected gains of the construction industry have been eroded by the failure of many construction projects due to unethical professional practices on the part of the construction professionals. This study analyzed the causes and effects of unethical practices on the industry and project delivery with measures to combat the unethical practices among the stakeholders. The study adopted the survey design and a stratified random sampling technique was used to select 140 respondents. A structured questionnaire was designed and administered to construction professionals (Architects, Quantity Surveyors, Builders and Engineers). The relative importance index tool was used to analyse the severity of the factors identified. Findings revealed the absence of punishment for unethical practices (0.94), collusion between officials, consultants and contractors (0.91), availability of loopholes in project monitoring (0.89), weak law enforcement institution (0.87) and greed for money (0.83) among others as major causes of unethical professional practices which have serious effects on the construction industry. The result also revealed poor workmanship and substandard project delivery (0.88), high cost of construction (0.86), the collapse of structures/buildings (0.82), inflated contract sums (0.81), high maintenance cost (0.79), time and cost overrun (0.76) as the extremely severe effects of unethical practices in the industry. Prosecution and punishment of offenders (0.98), the whilstle blower protection policies and rewards (0.84), strengthening of institutionand anticorruption agencies (0.78), award of contracts on merit (0.75) and civil society participation and oversight (0.68) were identified as highly effective measures to curtail unethical professional practices. The study recommends that the government being a major actor should abide by the due process of contract award and letting, using Public Procurement Act (PPA) guidelines in executing all its construction projects. The professionals, contractors and clients’ representatives should also exhibit high professional excellence through adherence to professional ethics and codes of conduct.

Assessment Strategies to Evaluate Building Information Modeling Capabilities of Organizations

With the advances in technology, Building Information Modeling (BIM) has been implemented in construction projects to minimize its complexity by increasing project efficiency and effectiveness. While BIM has been widely implemented, construction projects are still unsuccessful due to inappropriate BIM capabilities among organizations that are involved in the project. Therefore, this study aims to determine the strategies for assessing an organization’s BIM capabilities. The data collected through individual interviews with fifteen of BIM managers are analyzed using thematic analysis in order to achieve that objective. The findings suggest that the five parameters for evaluating an organization’s BIM capabilities are: documentation process, project track record, staff competencies, availability of BIM experts, and software maturity. This study contributes by providing a set of strategies for measuring an organization’s BIM capabilities in the construction industry. The lesson of this study would help researchers and industry practitioners prevent construction project failure from assessing project team members’ BIM capabilities before starting a project.
