This research used a quantitative approach with a questionnaire survey method for data collection. From the results of the literature study, 22 elements of the challenge to obtain procurement professionals were successfully identified. Questionnaires were distributed to ASN (public procurement officials), namely structural, functional and functional assistants working in the field of Procurement of Goods and Services within the West Sumatra provincial government. Furthermore, the data were analyzed using Exploratory Factor Analysis (EFA). As a result, there are three factors of the difficulty of obtaining functional procurement from the perspective of various ASN procurement managers, namely Standard and Policy Factors (6 variables), Transparency and Accountability Factors (4 variables), and Experience and Education Factors (2 variables). This research also suggests measuring the relationship between the three factors by means of confirmatory factor analysis for future research.","PeriodicalId":37954,"journal":{"name":"Journal of Design and Built Environment","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76663689","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}

Their adaptive principle relies on the dynamic management of the cavity's ventilation flow and the shading devices, which can integrate with the environmental systems. This research demonstrates the possibility of modifying existing buildings to study unconventional building envelope solutions. Scenarios A and B show insignificantly decreasing measures in air velocity, relative humidity, and air temperature; however, Scenario C shows the most significant changes, the average air velocity increases by 45%, the air temperature drops between 5 to 8%, and the relative humidity drops between 5 to 8%. The utilization of DSF can be used to reduce solar heat gain, enhance natural ventilation, and mitigate the inefficiencies of mechanical ventilation in educational buildings. The Double Skin Façade is effective in improving parameters that are in accordance with thermal comfort.","PeriodicalId":37954,"journal":{"name":"Journal of Design and Built Environment","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83043111","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}

Uncontrolled and rapid urbanization has transformed Dhaka into one of the world's largest megacities, leading to severe social problems. Therefore, it influences the city's social sustainability. Due to the lack of attention to social sustainability, especially in cities of developing countries, this study aims to measure the current status of social sustainability in Dhaka city for socially sustainable urban development. A structured questionnaire survey was conducted among residents of Dhaka. Results revealed that Dhaka city residents have low satisfaction levels regarding social sustainability conditions. They are not getting adequate facilities related to social sustainability for socially sustainable urban development. The results provide empirical evidence of the current status of social sustainability to policymakers, urban planners, and implementing agencies in Dhaka city that can assist in formulating appropriate socially sustainable planning, policy formulation, and practical implementation. The study might also help researchers in developing countries expand their thinking about other cities encountering similar problems.","PeriodicalId":37954,"journal":{"name":"Journal of Design and Built Environment","volume":"80 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74667330","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 problem of this study was: what types of wood joints were used in the construction of Ghumah Baghi? This study aimed to discover the typology and variations of joints based on geometry and arrangement. This study used a descriptive qualitative case study method. The data were collected through documentation, interview, and direct observation, and the analysis was carried out by comparing the types of wood joints from the literature. The research findings showed that there were 8 types and 36 variations of wood joints based on the theirition, shape, and unique geometry. Wood joints are affected by the availability of materials, geographical conditions, and assembly. Based on the typology of the wood joints, Ghumah Baghi construction is a knock-down construction resistant to earthquakes.

With the design process carried out by a team to achieve design constructability, implementing Value Management (VM) in Design Build projects is advantageous and can lead to cost-effective designs. While most studies have concentrated on identifying the important criteria that lead to the effective deployment of VM in infrastructure projects in general, the success factors of VM in DB delivery systems remain unknown. This study aims to identify the critical success factors (CSFs) in the three main stages of the VM workshop and their supporting factors in infrastructure projects delivered under DB system. To achieve the research aim, a questionnaire was distributed to DB contractors involved in infrastructure projects in Indonesia. The Relative Important Index approach was applied to 28 factors, and the analysis revealed the CSFs for each stage of the VM workshop, along with a critical supporting factor. The analysis revealed that there are three CSFs for the pre-study and study stages and one for the post-study stage. The identified CSFs provide a framework for VM success in Design Build projects. The three CSFs in the pre-study stage relate to VM objectives, project information completeness, and personnel involved in the VM workshop. At the study stage, VM success depends on the VM process, the development of alternative designs, and the VM team's innovation. In the post-study stage, VM success is linked to the VM implementation process and developing an execution plan. The cooperation of all stakeholders in implementing the VM workshop results is a critical supporting factor for VM in a DB project.","PeriodicalId":37954,"journal":{"name":"Journal of Design and Built Environment","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84782123","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}

Research in the past focuses on problem base approach which had little success in eliciting responses from stakeholders for sustainable change in their built environment. This research investigates accessibility experience in the built environment through social process of meaning-making based on positive and constructive interactions. This qualitative research using focus group discussion (FGD) employs an appreciative inquiry (AI) to collect and decode data in four stages; discovery, dream, design, and destiny. The FGD involved stakeholders including vulnerable communities; the elderly, pregnant women, mothers with toddlers, persons with disabilities (PwD), academicians and NGOs. Findings revealed collective priorities related to the accessibility improvements in the external and internal living environment, the need to enforce national disability law, the actualisation blueprint of the desired future living environment.

Due to a developing market and active supply-demand dynamics, the Malaysian housing industry has prospered. As a result, many investors are attracted to invest in property as it is one of the stable options to consider as compared to other types of investment. To date, there is no proper guideline as to which area is best to invest the money in as most investors are solely driven by profit but do not consider other factors that can sustain the income in the long term. Since investments are made with the goal of maximising wealth, investors must make reasonable choices based on the facts available and make a judgement that is devoid of emotion. By applying the COPRAS method to property investment, this research focuses on residential properties in Klang Valley, Malaysia. The main objective of this research is to provide an idea to investors on which area in Klang Valley can ensure sustainable investment, particularly residential properties. The final findings show that Petaling best conforms to sustainable investment with the highest degree of utility as compared to other alternatives. It is followed by Klang and the Federal Territory of Kuala Lumpur. This research provides additional literature that may help investors during their investment decision on which area is the most sustainable to invest in Klang Valley.","PeriodicalId":37954,"journal":{"name":"Journal of Design and Built Environment","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85075122","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}
