{"title":"Non-toll revenue potential to increase funding sources for toll road maintenance","authors":"Betty Susanti, E. Kadarsa, M. Foralisa, Ika Juliantina","doi":"10.5130/ajceb.v23i3/4.8876","DOIUrl":"https://doi.org/10.5130/ajceb.v23i3/4.8876","url":null,"abstract":"The purpose of providing toll road infrastructure through Public-Private Partnerships (PPP) is to ensure that the private sector generates sufficient revenue to manage road operations and maintenance effectively. However, in many countries, various practices of PPP have led to budget shortfalls for road operations and maintenance. This situation is often due to escalating construction costs and lower-than-expected traffic volumes. To address these financial challenges, this study aimed to implement asset commercialization schemes within toll road management. A specific case study was conducted on a section of the Indonesian Trans Sumatra toll road that faced rising construction costs and low traffic volumes. A quantitative approach was applied to assess potential non-toll revenue that could be generated through asset commercialization along toll road corridors. The commercialization opportunities considered included leasing land for advertisements, installing solar power plants, erecting communication towers, and establishing rest area businesses. The identification and analysis of these opportunities were closely tied to the type, quantity, and location of asset. The results showed that asset commercialization schemes, particularly land leases for advertisements and rest area businesses, had potential to generate substantial revenue. It showed that by fully capitalizing on asset commercialization opportunities along toll road corridors, significant additional income could be generated to support road maintenance funding. The approach developed in this study could be applied to other toll road sections facing revenue deficits and budgetary challenges in maintaining their operations. This study could contribute to the growing body of knowledge on the commercialization of toll road asset.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139011333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Barriers to the Adoption of Digitalization in the Construction Industry: Perspectives of Owners, Contractors, and Contractors","authors":"Waleed Abu-Khader","doi":"10.5130/ajceb.v23i3/4.8636","DOIUrl":"https://doi.org/10.5130/ajceb.v23i3/4.8636","url":null,"abstract":"Construction organizations are moving toward adopting digitalization in response to Industry 4.0. However, the slow adoption of digitalization has been observed. This study aimed to assess the level of digitalization adoption and evaluate the barriers to adopting digitalization in the Jordanian construction industry by all project parties in the public and private sectors. The study targets were achieved through a structured questionnaire using SPSS software for analysis through the following statistical tests: Normality test, Mann-Whitney U, Kruskal-Wallis H, and Exploratory Factor Analysis (EFA). Most respondents used software at the design stage, and less than half did not use any software during the finishing stage. Regarding the barriers, twenty barriers to adopting digitalization were identified and grouped into five factors according to their importance: barriers related to the nature and system of the construction company, barriers related to the project parties, financial barriers, barriers related to system characteristics, and barriers related to construction project characteristics. Decision-makers should take the necessary measures to overcome such barriers depending on their importance. Previous studies have focused on the contractor's adoption of digitalization while neglecting other parties. This contributed to the full adoption of digitalization from the contractor side, with a noticeable delay from other project parties. This study focused on revealing the most critical barriers to adopting digitalization in the Jordanian construction industry from all project parties' perspectives based on their ranks. Furthermore, the study recommends effective strategies to overcome barriers as an update of past research.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139010951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Changes in design, work scope, and construction turn into rework and affect the contract sum, the project completion date and project performance. Thus, clear responsibility to manage rework is essential for construction contracts. Contractual rework provisions are difficult to trace as they are written indirectly or in a complex context. A well-defined contract with clear responsibilities before the project commencement will safeguard the contract from unforeseen circumstances. In this study, the stipulated provisions related to the causes of rework are reviewed and analysed in New Zealand standard form of contract. The research uses a mixed quantitative and qualitative method for data collection and analysis. This paper collects a list of rework causes, assesses each rework cause in the general contract conditions, and explores relevant rework clauses of NZS3910 contract. The study revealed five significant causes of rework that have been addressed in the contract conditions. Further investigation into the reminder causes during contract negotiation enables contract parties to manage their obligations under rework events. Properly addressing the causes of rework in the contract conditions improves the overall project performance and reduces contractual claims and disputes.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139010941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deegahawature, Renuka Silva","doi":"10.5130/ajceb.v23i3/4.8780","DOIUrl":"https://doi.org/10.5130/ajceb.v23i3/4.8780","url":null,"abstract":"This study primarily identifies the knowledge gaps that must be filled to apply conceptualised methods for rising and benchmarking productivity levels of various construction operational tasks. Accordingly, this study intended to evaluate labour productivity in relation to labour performance using potential apprenticeship instruments and systems. Comprehensive literature analysis and expert consultations were carried out to create a new mechanism with the collection of potential models, methods and systems connected to labour training, performance evaluation and productivity measurements. A total of 23 construction projects in Sri Lanka employed the created approach methodically. The results demonstrate the precise patterns of substantial shifts in labour productivity and performance index values, which have sparked new conceptual mechanisms for construction project planning methods. The outcomes demonstrate that the suggested approach can be used in a way that is reliable, generalisable, productive and sustainable. The study provides project managers, planners and engineers with a new road map and helpful techniques to raise the standard for measuring labour productivity levels across a variety of jobs. The overall study outcomes strengthen the chain relationship among the training elements, labour skills, performance and productivity. Though the study findings were limited to the construction industry and Sri Lankan context, the study outcomes are expected to make a significant impact on the current practices of various industry sectors in many developing countries for achieving higher productivity levels in work operations. This paper discusses some more implications and future scopes of the study elaborately.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139011320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was during such a musing that a colleague from UTS/OJS pointed out that this journal had produced a suite of highly cited papers that was continuing to grow. They went on to illustrate the point with a list that stopped at a lower limit of 30 citations, observing that there was every likelihood that further good, recently published papers would continue this habit, given sufficient time (3-5 years). \u0000  \u0000Grateful for their observations I scanned the list and was buoyed by the thoughts that these papers were a product of their time (i.e. highly relevant, reflecting topics of contemporary and ongoing concern), clearly well executed – conceptually and methodologically – and written in an engaging style. They were, and self-evidently continue to be read and cited, though the issue of growing our readership continues to be a challenge. \u0000  \u0000In a world of burgeoning journal titles, many of which appear to be predatory in nature it can become necessary to remind readers of this tome that it is a valuable venue for the best of their research.

González-Díaz","doi":"10.5130/ajceb.v23i1/2.8163","DOIUrl":"https://doi.org/10.5130/ajceb.v23i1/2.8163","url":null,"abstract":"In the last years, the increase in urbanization and the volume of construction has accelerated. This situation requires systematizing the use of limited resources, especially in island territories. The construction sector contributes to the depletion of these resources and has a significant impact on society, which is why it is necessary to change its strategy and decision-making. Corporate Social Responsibility (CSR) may be the strategy to develop a socio-environmentally responsible production model that replaces the traditional model. A socially responsible construction company closes the cycles of construction materials, gives value to the waste generated, minimizes the impact that buildings have on the environment, makes responsible use of energy and water, uses innovations to improve the process and adequately manages its human resources. The aim of this work is to analyze the socially responsible behavior of companies in the construction sector in a limited and fragmented territory as is the province of Santa Cruz de Tenerife and to compare the importance that companies give to actions (environmental, social and economic) of CSR depending on whether they have been implemented or there are plans to implement them in the future. Quantitative and qualitative tools are used. The results indicate that aspects related to environmental sensitivity and social contribution contribute to a greater extent to the implementation of a CSR strategy, while economic aspects have a negative influence. In the case of companies that plan to implement a CSR strategy in the future, the aspect related to social contribution is the most influential.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89948039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that the advance payment term, the period of an interim payment term, the period to make a payment term, and the project price conditions had average utility ratios (ratio of its utility to the total utility) of 28.53%, 20.24%, 20.41%, and 25.87%, respectively. These results confirmed that each of these three contract terms are as important to interior contractors as the project price condition (no price reduction by 5% of the proposed price). This study also valued the three contract terms by comparing their utility with the utility of the project price condition. The values of the terms to the interior contractor were as follows: the value of the advance payment term varied between 0.00–11.67% of the proposed price; the value of the period of the interim payment term varied between 1.25–8.33% of the proposed price; and the value of the period to make a payment term varied between 2.00–11.67% of the proposed price. The value of all three contract terms varied between 12.00–20.00% of the proposed price.

However, the construction industry still struggles to capture and disseminate lessons learned. The present research explores this issue by using interviews and an online questionnaire, to provide updated information on lesson-learned procedures and their challenges in United States (US) construction companies. To do this, the authors have gathered industry professionals’ perceptions about lessons learned and methods used in their companies for harnessing and disseminating the knowledge generated by them. Our findings indicate that post-project evaluations are frequently conducted, utilize a two-step approach (review of materials followed by meetings), and are mainly organized by project managers. Most often, only key project team members are present in meetings to create a safe environment for discussion. Moreover, our findings echo previous research on the dissemination and reuse of lessons learned, indicating that these procedures are scattered and, most of the time, the information is not effectively reutilized. This suggests that US construction companies still need to revisit how information from lessons learned is currently being harnessed, stored, and especially shared (within and between companies) so that information can be effectively transformed into knowledge that can advance the AEC industry's productivity.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76438335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, a large body of recent research has focused on identifying the best practices for accelerating recovery and restoring impacted communities. However, relatively little attention has been devoted to the health and safety challenges experienced by reconstruction workers that aid post-disaster recovery and reconstruction efforts. The current investigation focused on addressing this knowledge gap by seeking to uncover the health and safety challenges that reconstruction workers experienced in the context of the 2015 Gorkha earthquake in Nepal – that was responsible for nearly 9,000 deaths and 22,000 injuries. The data collection effort involved in-depth interviews with several stakeholders, including construction workers, supervisors, site engineers, general contractors, homeowners, and governmental officials.
