These goals may not be achieved if firms’ psychosocial construction work environment and wellbeing (PCEW) are not appraised. To this end, this study identified and assessed factors relating to PCEW in the 37 factors influencing the viability and performance of construction firms obtained from the extant literature. A sample size of 65 staff of 31 ICFs out of a total survey of 177 staff of 59 ICFs that were awarded building contracts in selected institutions in Nigeria was accessed for this study. Respondents rated each factor on a five-point Likert scale of importance and mean scores were used to rank the factors after identifying factors that are related to ICFs’ PCEW. The study identifies 14 PCEW related factors out of the 37 factors influencing the viability of ICFs and six of the top ten very important factors influencing ICFs’ viability having high factor loading are PCEW related. The factors are quality of construction work and services, availability of skilled labour, employee satisfaction, and availability of artisans and craftsmen. Steady emphasis on factors influencing PCEW of construction workers amidst various factors influencing ICFs’ viability is necessary for a healthier construction work environment and wellbeing.","PeriodicalId":53274,"journal":{"name":"Journal of Engineering Project and Production Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46182335","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 Gulf Cooperation Council (GCC), of which Oman is a member, faces huge delays on their projects. Such delays in the GCC were among factors fingered in the collapse of the UK’s Carillion. Despite cultural similarities, substantial variability exists within the GCC construction sector which requires country-specific studies. The quest to understand delay causes results from the need to curtail wastes and adjust to the new regime of low commodity prices. There is a dearth of studies specific to the governorate of Muscat exploring the causes of delays and this study seeks to fill that gap. A structured survey questionnaire was administered at two independent events organized by the RICS and ICE in Muscat. The top causes of delays ranked using the Relative Importance Index (RII) include variation and changes in design, Poor site management and supervision, ineffective planning and scheduling, unclear and inadequate details in drawing, poor qualification of the contractors and technical staff, delay in material delivery, and shortage of labor. Contractors were found to be most likely to cause delays among the 6 categories of sources.","PeriodicalId":53274,"journal":{"name":"Journal of Engineering Project and Production Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45587198","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}

Despite the several advantages it offers, its application has been limited to smart building integration only. This study has made a significant contribution by integrating voice recognition technology into key-in building quantities estimation software. The Visual Basic programming language was used to design and code the interface of the voice recognition system and key-in estimating software model. The prototype model continues to have some challenges because it cannot work efficiently in a noisy work environment and there is limited range of vocabulary it can recognize. This paper seeks to challenge the stakeholders of the construction industry to maximize the benefits of voice recognition technology and integrate it into other construction tasks. In addition, future research can consider integrating building information modeling and voice recognition technology.","PeriodicalId":53274,"journal":{"name":"Journal of Engineering Project and Production Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45734738","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 Zambian building sector normally experiences time and cost overruns. This study investigated the feasibility of using tilt-up construction in the construction of commercial building walls. The methodology used consisted of a literature review, a questionnaire survey and a scenario analysis consisting of a hypothetical 4900 square meter commercial building with a height of 8 meters. Sixty-six questionnaires were administered to design professionals operating in the Zambian building sector using simple random sampling and thirty-six were returned giving a response rate of 55%. The data were analyzed using descriptive statistics. Cost analysis was done on a hypothetical building as no contractor was found using tilt-up construction in the construction sector. The study established that tilt-up was, in fact, more expensive than the conventional methods (concrete blocks and in-situ reinforced concrete walls), but it was faster, hence, making it viable in respect to time and not cost in the Zambian construction industry (ZCI). Additionally, necessary expertise was available with the exception of a certified tilt-up practitioner and a sealant sub-contractor in cases where a sealant contractor is needed. The study has identified that currently in the Zambian building sector tilt-up construction can be used when time is more important than the cost. However, challenges such as site size (limited space), the unavailability of building regulation for tilt-up construction and the economic capacity of the client or capacity need to be addressed for enhancing the practical application of tilt-up construction in ZCI.","PeriodicalId":53274,"journal":{"name":"Journal of Engineering Project and Production Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45219946","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":"Capacity Building in Participatory Monitoring and Evaluation on Sustainability of Food Security Irrigation Projects","authors":"O. Rogito, T. Maitho, A. Nderitu","doi":"10.2478/jeppm-2020-0012","DOIUrl":"https://doi.org/10.2478/jeppm-2020-0012","url":null,"abstract":"Abstract health-related problems and even death among animals and human beings. Agriculture is the main food source; thus, many interventions are made such as that of irrigation by the local county and national government initiated through the National Irrigation Board (NIB). Despite the irrigation projects food insufficiency still persists, therefore their sustainability is questionable. One such approach to improving the sustainability of irrigation projects is participatory monitoring and evaluation which leads to ownership and then higher sustainability. In the study, the objective was to asses if taking corrective action after participatory monitoring and evaluation (PME) influence project sustainability. The study used a descriptive survey and correlation designs to collect data from 316 respondents selected using stratification sand purposeful with strict randomization. Questionnaires were administered and interviews were conducted on selected sample respondents on appointed dates. Data were analyzed using SPSS version 25.0 to get descriptive statistics, correlations coefficients were obtained to test association and degree of strength. Testing of the hypothesis was done using linear regression. The study findings were that a large number of respondents were between ages 31 to 40 years and most were female with their highest level of education being primary school. The influence of PME capacity building on the dependent variable and irrigation projects sustainability found that the farmers were not taken for exposure visits and project officers were not accountable for money use. Age, gender, and education level have very minimal influence on PME capacity building. PME capacity building had a weak positive influence of r = 0.290 and it explained only 8.4% of irrigation projects sustainability in Kitui County. The study recommends that to improve project capacity building: project revenue must be controlled on use, farmers must be taken for exposure visits to learn from successors, project officers should be accountable for funds use, and project guidelines should be improved to increase sustainability. Implementation of these recommendations will reduce the loss of Arid and Semi-Srid Lands (ASALs) and attain higher and longer sustainability in food projects, thus, reducing the recurrence rate of food shortage, improve and hasten the implementation of irrigation projects, show the need to involve primary stakeholders in project monitoring and appraisal for sustainability, better and efficient decisions by policymakers to increase chances of project’s success.","PeriodicalId":53274,"journal":{"name":"Journal of Engineering Project and Production Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47913575","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 requires new strategies for compliance with national and international scenarios. Developing each project is associated with many limitations, including time, cost, changes, wastes, and errors, which are often not avoidable. Due to numerous project stages and complexities in the construction industry, usually, different mistakes and duplications occur. Meanwhile, Building Information Modeling (BIM) has created one of the most important and essential changes in this industry and results in more in-depth cooperation among project stakeholders. BIM is one of the most recent innovations in the construction industry, which resolves the problems of projects faster. BIM can be applied by architects, engineers, contractors, project managers, etc. to achieve objectives such as reducing design errors, reducing time and cost, improving design and construction integration, and increasing coordination and cooperation among different sections. Given the significance of project success in every country and several problems in each project, using BIM is an appropriate solution, which its proper implementation requires understanding its benefits that is the main aim of this study.

These risks affect the achievement of projects objectives and therefore need to be identified and treated to guarantee project success. This paper developed a life cycle framework for managing risks in PPP housing projects in Nigeria. The respondents were selected using purposeful sampling technique. The data used for the study were obtained through semi-structured questionnaire and were analysed using mean rating. Risk transfer was found to be the widely used measure for responding to risks in PPP housing projects. The criteria mostly used for risk allocation were party with the best ability to manage specific risks should they occur and ability of the party to foresee risks. A four-stage life cycle framework was developed, evaluated and validated by experts in the built environment to ascertain its reliability.
