Influences of critical success factors on nonprofit outcomes of ODA education construction projects: a case of Vietnam

Purpose Official development assistance (ODA) education projects have played a crucial role in improving education and training fields in developing countries, but are often facing several considerable challenges (e.g. long implementation time). Thus, this study aims to identify critical success factors (CSFs) in ODA education projects and investigate the influences of CSFs on ODA project performance measured by 11 nonprofit outcomes (NPOs). Design/methodology/approach A comprehensive literature review and expert interviews were conducted to compile a list of 35 potential success factors for ODA education projects. Using a survey questionnaire, 143 valid responses were collected from practitioners joining ODA projects in Vietnam. Various statistical methods (e.g. mean score method, Spearman rank correlation test, analysis of variance test, factor analysis and regression analysis) were used to analyze the collected data. Findings This research identified seven CSFs for ODA education projects in Vietnam: comprehensive project management competency (C1), clarity and compliance in project execution (C2), transparency and committed funding (C3), external context conditions (C4), well-controlled design and project management procedures (C5), preparations in equipment and complexity insight (C6) and punctual site delivery (C7). Furthermore, the results of regression analysis indicated that comprehensive project management competency (C1) and transparency and committed funding (C3) could significantly affect various NPOs. Originality/value This study offers significant insights for practitioners (e.g. project managers) to improve ODA projects’ performance and effectiveness in the education and training sector of a developing country context (like Vietnam).

The Impact of Leadership Behaviour on Management Effectiveness in Public Construction Project Organizations

This study aims to explore the less explored area of leadership behaviors within public construction project organizations. A correlational research design was adopted, with data collected through a questionnaire-based survey of 169 professionals involved in public construction projects in Vietnam. Structural equation modeling with partial least squares estimation was used to analyze the data. The results confirmed five behavioral dimensions, namely motivating leadership, goal setting, supportive leadership, participative leadership, and directive leadership, which can be used to assess the leading function in public construction work management. The study also revealed that supportive leadership and directive leadership have a significant impact on management effectiveness. Additionally, supportive leadership acts as a mediator for goal setting, motivating leadership, and participative leadership, while directive leadership acts as a mediator for goal setting and participative leadership.

Significant factors affecting the Vietnam Roads Infrastructure Construction Cost Overrun - A Review

Cost overrun represents a significant challenge faced in construction projects, particularly in the realm of transportation infrastructure. The investigation into the causes of cost overruns in such projects has garnered substantial attention from both academics and the general public. Various studies conducted globally have identified diverse factors contributing to cost overruns. This article undertakes a critical review of the literature on cost overruns in construction projects, encompassing cases from different countries with a specific focus on Vietnam. The aim is to identify and comprehend the primary potential causes of cost overruns in construction projects across various geographical contexts, providing insights into both commonalities and distinctions within the identified factors. According to the findings of this study, the ten identified factors encompassing Delay in site clearance certificates, Change Management, Delay in Payment, Extension of the project implementation schedule, Construction Material Price Fluctuation, Effects of inflation and price slippage, Poor construction site management, Poor project management capacity of the investor, Poor financial capacity of the investor, Geological complexity are deemed highly influential and warrant close scrutiny during the implementation of projects in Vietnam. The insights gained from this study will serve as invaluable recommendations for active entities within the construction industry to adopt a more holistic approach to project management, cost control, and cost overrun management. By addressing quantitatively these factors in the forthcoming research, organizations in construction industries in Vietnam can effectively minimize project costs overrun in the future.

Determinants of financing decisions for renewable energy projects: A case study

Renewable energy sources have never been more affordable and are now significantly undercutting fossil fuels as the world’s cheapest source of energy. Otherwise, it can benefit the environment, economy and society in the long term. However, financing and investment barriers play an important role in order to encourage renewable energy projects in Vietnam. In this research study on factors affecting investment decisions in renewable energy, along with behavioural and institutional theories, the authors have pointed out that financing decisions (FD) for energy projects in Vietnam are also influenced by non-financial factors. In this paper, we developed the model by using four factors: a priori beliefs (PB), institutional influence from legal obligations (IO), institutional influence from normative sources (IN), and knowledge of renewable energy operational context (KC). Structural equation modelling (SEM) is used to analyze determinants of the decision-making of financial institutions. Similar to Giang (2022), our result shows the important role of the PB in the effectiveness of renewable energy’s existing policies and technological adequacy, KC as well as the IN in renewable energy FD of institutional investors. Meanwhile, IO does not impact the investors’ willingness to finance renewable energy projects.

Assessing critical barriers and success factors of PPP projects in emerging economies: a case of Vietnam

Purpose Public–private partnership (PPP) projects play a pivotal role in fostering infrastructure development in developing countries. This study aims to identify major barriers and critical success factors (CSFs) for PPP projects in Vietnam. Design/methodology/approach The study initially conducted an extensive literature review and interviewed industry experts to compile a comprehensive list of barriers and success factors. Subsequently, a survey involving 250 construction professionals was conducted to assess these identified factors. The research used both ANOVA test and hierarchical regression analysis to explore the relationship between participants’ characteristics and assessments. Findings The results could provide a valuable reference for practitioners by assessing barriers and CSFs in PPP projects. Specifically, the ANOVA analysis indicated a positive correlation between barrier assessment and participants’ experience, while the influence of participants’ sector on the evaluation was minor. Furthermore, the hierarchical regression analysis demonstrated that participants’ sector did not moderate the relationship between barrier assessment and industry experience. Originality/value This research contributes to the existing literature by offering empirical insights into barriers and CSFs specific to PPP projects in a developing country context. The findings highlight the crucial role of experienced professionals in ensuring PPP project success. Moreover, the study provides construction practitioners with a better understanding of the essential factors and supports the development of effective management strategies for future PPP projects.

Estimation of recompression coefficient of soil using a hybrid ANFIS-PSO machine learning model

Recompression coefficient (Cr) is =an essential parameter utilized to predict consolidation settlement of over-consolidated soil. Thus, the main aim of this work was to estimate accurately the Cr, using a hybrid ANFIS-PSO Machine Learning (ML) model that is a hybridization of Adaptive Neuro-Fuzzy Inference System (ANFIS) and Particle Swarm Optimization (PSO). To compare the performance of proposed model, we selected two other benchmark ML models: single ANFIS and Support Vector Machines (SVM). We collected and utilized the data of304 soil samples tested from various construction projects in Vietnam, which included 12 input variables (soil parameters) and one output variable (Cr). Validation indices, namely Correlation Coefficient (R), Root Mean Square Error (RMSE), and Mean Absolute Error (MAE) were utilized for the validation of the model’s performance. Correlation analysis of feature selection results indicated that seven input variables namely clay content, plasticity index, liquidity index, degree of saturation, specific gravity, dry density, and bulk density were of importance and thus selected for prediction of the Cr. Validation results indicated that predictive capability of the hybrid ANFIS-PSO model (R = 0.802) is the best in comparison with other two benchmark models namely SVM (R = 0.727) and single ANFIS (R = 0.734). The findings of our study suggest that the ANFIS-PSO is a powerful ML tool for effectively and quickly prediction of the Cr of soil. This can help save time and reduce costs associated with laboratory experiments for determining this important geotechnical parameter.

The effectiveness of using a mechanically stabilised layer for unpaved roads in Vietnam: Some case studies

The construction of onshore wind powers requires an access road network, whose pavement design is challenging due to the complexity of ground conditions subjected to heavy vehicles. A thick pavement structure, therefore, is often required following the conventional design method, leading to uneconomic designs and solutions. The use of multi-axial stabilisation geogrids to form a Mechanical Stabilised Layer (MSL) was considered to optimise the pavement structures as well as to reduce material costs, construction time, and carbon footprint of construction activities while maintaining the technical requirements. This paper presents experimental tests conducted in wind power projects in Vietnam to evaluate the pavement performance with and without MSL. A comparison between stabilised and conventional sections is analysed in terms of the modulus of elasticity, rutting depth, and carbon emission reduction. The study results can be applied to pavement design procedures for residential roads, industrial roads, and highway projects.

IMPACTS OF GOVERNANCE CONSTRAINTS ON ODA PROJECT QUALITY: EXPLORATORY STUDY

Effective project implementation is critical to the success of transportation projects and significantly contributes to the productivity and economic growth. Unfortunately, many transportation projects in developing countries have not yet met their expected outcomes. This study aims to explore the governance constraints in the construction phase and their impacts on the quality of the transportation projects funded by the official development assistance (ODA). Based on 340 survey questionnaires collected from both national and provincial project management units (PMUs) in Vietnam, the mean score method was first used to rank the governance constraints in construction. The results showed that site clearance and handover, capital shortage and parties’ incompetence and irresponsibility were assessed to be the most significant governance constraints by both managers and other members involved in ODA-funded transportation projects. Following the results of one-sample t test, a significant difference between ODA-funded and government-funded projects was also found on five constraints: site clearance and handover, capital shortage, delayed payments to contractors, donor involvement, and cost escalation. In addition, the results of regression analysis indicated that project quality could be significantly affected by such constraints as site clearance and handover, changes in scope of work, review/approval of change orders, cost escalation, and imported long-lead items. These results together could provide international sponsors and practitioners with some useful insights to better implement ODA-funded transportation projects in Vietnam and other developing countries.

South Korea–Vietnam–India Trilateral Economic Cooperation: Prospects and Policy Implications

Great attention has been paid to the bilateral economic relations between India, Vietnam, and South Korea; however, only scant research has focused on the prospects of triangular economic cooperation among the three countries. Given the advantage and demand for the cooperation of each party, there is significant potential for trilateral economic cooperation among South Korea, Vietnam, and India. In this paper, we discover the prospects for their triangular economic cooperation in three aspects. First, this study examines the potential for cooperation in production networks and supply chains between the three countries in the context of reconfiguring the global value chains (GVCs), with a focus on the leading role of South Korean multinational enterprises (MNEs). Second, the study explores trilateral cooperation in the digital economy and connectivity, focusing on how South Korea and India can collaborate on investment projects in Vietnam. Third, this study discusses the rationale and possibility of forming a regional trade agreement (RTA) between the three countries. South Korea, Vietnam, and India have extant bilateral trade agreements between two of the three countries; however, there is no regional integration among the three countries discussed in specific. Considering the bilateral relations and domestic and external factors, the paper reckons that an RTA for starters between the three countries would be mutually beneficial to each of the corresponding economies.

Application of inclined big‐diameter jet grouting for urban tunnel construction in Vietnam

AbstractUrban tunnel construction is often performed in congested areas with many buildings and historical structures nearby. With respect to developing countries, such as Vietnam, the lack of as‐built drawings of existing buildings is a big challenge for urban tunnel development. There are a lot of private buildings in downtown are low rise, with many kinds of shallow foundations (from bamboo bar, brick mat, lean concrete mat, pre‐casted concrete piles…) that add to the challenge of finding correct data. Consequently, one must find suitable and reasonable technology for the soil strengthening works in order to prevent the harmful impacts to the third ‐party properties and the tunnel structure itself. This paper introduces the inclined big‐diameter jet‐grouted column (iBDJ) technique that was recently applied with success in Hanoi Metro Line No3 project in Vietnam. This technique for protecting historical sensitive buildings that are in fuzzy of foundation information can be extended to urban tunnel projects in Vietnam and other countries which have similar conditions.

Technology costs for the first wave of wind farms in Vietnam: Paying extra for better wind nearshore

Technology analysts often dichotomize wind power projects as onshore vs offshore. They neglect nearshore projects installed in the intertidal flats. We explore the characteristics of this intermediate category using an original sample of Vietnam's wind power projects for the 2018–2021 period. The median investment for onshore wind power projects in Vietnam is 1695 USD/kW. It is 2011 USD/kW for nearshore projects. Nearshore wind-power generation capacity requires about 20 % more investment per MW than onshore, inter-quartile range of 0 % – 45 %. Nevertheless, nearshore projects remain much less capital-intensive than far-offshore projects – projected at 3150 USD/kWh in Vietnam based on experience in OECD countries with fixed-bottom projects. Escaping the onshore vs offshore dichotomy allows us to consider a different policy direction for the industry. Rather than pursuing bluefield mega-projects far offshore, a “small steps” policy to extend nearshore wind farms may be cheaper, faster, and more institutionally feasible.

Factors affecting the delay of urban development investment projects: A case of Vietnam

The project implementation schedule is an important plan for every construction project, to reduce and control project delays. The implementation of urban development investment projects is increasing in terms of both quality and quantity as urban areas are rapidly developing in cities. However, many construction projects are scheduled but they are late from due time. As the number of urban development investment projects increases, understanding the causes of project delays will help project managers and stakeholders limit these delays. This paper investigates all those factors which are causing a delay in the development of urban investment projects These factors are further developed through expert knowledge elicitation using the Delphi method. Lastly, as based on the issues identified were run to determine how they affected project delays. Finally, a survey based on the issues identified factors was conducted to assess how they affected project delays. The linear regression model is used to analyze the results from the survey. The results of the study indicate that there are six main factors that cause the delay in the implementation of urban development investment projects in Vietnam, including Policy, Design, Cooperation, Implementation, Financing and Objective factors. The study's findings indicate that there are six primary groups of elements, including Policy, Design, Collaboration, Implementation, Finance, and Objective factors, that contribute to the delay in the execution of urban development investment projects in Vietnam. The study offers a research model for the factors that contribute to delays in the execution of construction projects for urban development. This finding can serve as a foundation for ideas on how to deal with this issue in Vietnam as well as a guide for similar works.

Maintenance Policies and Practices on Resilient Houses: Case Study from a Coastal Resilience Project in Vietnam

Vietnam is a country that experiences extreme climate conditions and annual accumulated damage due to typhoons and floods, which seriously destroy houses and cause many deaths. Approximately half a million people currently living within 200 m from the coastline live in unsafe houses. Therefore, the Coastal Resilience Project (the project) was implemented to build 4000 storm- and flood-resistant houses for five coastal provinces in Central Vietnam. The paper is carried out to review existing policies and practices related to the maintenance of resilient houses, as well as to propose feasible maintenance solutions for houses to ensure the sustainability of the project. The result shows that currently, there are no technical instructions or manuals on the maintenance and repair of individual houses in general, or the project houses in particular. Most of the households in the project also have very low and unstable incomes. In addition, as they lack knowledge of how construction works, they know little to nothing about the maintenance of a house. From these findings, the authors recommend several solutions for better maintenance policies and practices on the resilient houses of the project in Vietnam. The project provides several lessons in terms of the maintenance of the resilient houses of future projects in Vietnam and elsewhere, by reviewing existing policies and current practices, as well as proposing feasible measures to ensure the sustainability of the project. The findings in this paper provide valuable information for better maintenance policies and practices of resilient houses for other vulnerable coastal provinces in Vietnam and similar contexts elsewhere.

Delivering transport infrastructure using state-owned enterprises (SOEs): A business history of Vietnam Expressway Corporation between 2004 and 2016

Adopting a business history approach, this paper explores the role and evolution of Vietnam Expressway Corporation (VEC) as a state-owned enterprise (SOE) delivery model for five highway projects in Vietnam's first phase of network development between 2004 and 2016. It draws upon insights from the field of transaction cost economics and resource-based theory to explain why the Vietnamese government employed the SOE model instead of traditional public procurement (TPP) or public private partnership (PPP). The case study shows the government chose to use an SOE to achieve dual policy goals: (1) accelerate the preparation and construction of five priority highways and (2) reduce fiscal pressure on the state budget. As a toll-funded SOE responsible for both the lifecycle delivery of highway infrastructure and debt repayment, VEC effectively economised transaction costs and maximised financial resources from both government and market sources, including a mix of international loans from major development institutions. The SOE model's unique advantages were also difficult to imitate by TPP and PPP. More specifically, the public ownership and not-for-profit mandate of the SOE model gave the government flexibility to effectively mitigate the adverse impacts of unforeseen project-specific risks and macroeconomic uncertainty on project performance. Taken together, these findings contribute to growing academic interest in the role of modern SOEs as a delivery model for transport infrastructure.

Factors Affecting the Success of PPP Transport Projects in Vietnam

Transport infrastructure plays an important role in the development of each country, especially for developing countries like Vietnam. To promote the development of transport infrastructure as well as to deal with some challenges such as budget and project efficiency, the Public Private Partnership (PPP) model is a very proper choice. The factors that determine the success of PPP transport projects are important issues to be analyzed in different countries. The article aims at identifying the factors and the extent of their influence on the success of PPP transport project in Vietnam. Research data are collected from surveys with questionnaire to capture related partners' perceptions of success factors. The influence level of the factors is assessed on a 5-point Likert scale (from 1 -very low to 5 -very high). A total of 92 questionnaires were collected and analyzed using Statistical Package for the Social Sciences (SPSS) software to rank the influence of success factors. Research results show that “Adequate and transparent legal framework”, “State and private commitments and responsibilities”, “Transparency in bidding”, “State support policy” and “Good governance” are the top five factors determining the success of a PPP transport project in Vietnam. The new findings of the study help the State and investors better understand the factors determining the success of PPP transport projects in Vietnam in order to make appropriate decisions on policies.

Roadworks design: study on selection of construction materials in the preliminary design phase based on economic performance

The preliminary design phase transforms the investor’s ideas and information into general plans, drawings and specifications and helps the project managers continue the next steps in the projects. Material selection is an essential task to incorporate sustainable content into the construction industry. This paper reviewed materials selection studies and proposed a comprehensive method to compare the economic performance of construction material alternatives in this phase. The article constructed a life cycle costing equation used in the preliminary design stage that compared the total expected cost of the alternatives throughout the road construction project life cycle. The proposed life cycle cost method was divided into two scenarios according to the available information in the preliminary design phase and the material-dependent costs. A case study in Vietnam about the selection between baked bricks and concrete bricks was presented to demonstrate the proposed equations and models. The result showed that the baked bricks took the top priority due to the differences in cost items (e.g., transportation costs). Furthermore, to validate the models, they were applied to compare the expected and actual cost of 18 road construction projects in Vietnam – the differences are all below 10%. Further research may focus on building a database of models by applying the Building Information Model (BIM).
