However, there is limited knowledge of the outbound logistics channels for construction material in Nigeria. This study aims to identify and examine the current outbound logistics channels used by the Nigerian construction material manufacturing industries. A quantitative research method using a case study approach was adopted in this research. The purposive sampling technique was chosen, where six construction material manufactured and distributed within five states capital and Abuja in the North-central region of Nigeria were selected for this study. A research instrument was developed and used in conjunction with an observation protocol in the form of a template. The data were collected through observations, direct measurement onsite and archival records of transactions. A descriptive method of data analysis was employed to analyse the data. Our findings indicate that there exist six alternative outbound logistics channels that can be used separately or in combination with each other to deliver materials to end users. The study concludes that the research finding provides a potential knowledge and understanding of the manufacturers’ outbound logistics channels that can be used at the start of a project to accomplish effective planning and delivery of the whole project. The study also established the average transportation cost per average ton and average transportation cost per average distance driven for construction material delivery. This information can be used for construction material transportation management.","PeriodicalId":53274,"journal":{"name":"Journal of Engineering Project and Production Management","volume":"10 1","pages":"19 - 26"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44645670","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 outcome uncover product innovation as the main type of innovation among different types of innovation and generally in charge of the accomplishment of the CMSMEs considered. The investigation improves the collection of learning regarding basic types of innovations within CMSMEs and proposes that effective CMSMEs give more consideration to product innovation to trigger their prosperity and different types of innovation. Moreover, the aftereffect of the examination proposed failing CMSMEs can endure when they focus on product innovation.","PeriodicalId":53274,"journal":{"name":"Journal of Engineering Project and Production Management","volume":"10 1","pages":"11 - 18"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44168906","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":"Improving the Performance of Building Construction Firms through Addressing the Gap of Building Production Management: A New Production Model Approach","authors":"I. Osuizugbo","doi":"10.2478/jeppm-2020-0007","DOIUrl":"https://doi.org/10.2478/jeppm-2020-0007","url":null,"abstract":"Abstract Gap of building production management (BPM) is a serious issue that influences project success and building construction firms’ (BCFs) performance. Hence, the call for BCFs performance improvement using a new production model approach is a necessity. The aim of this study is to investigate the role of the new production model concept as a method for enhancing the performance of BCFs through addressing the gap of BPM in Nigeria. To attain this aim, a research procedure was designed to achieve two objectives which include: (i) exploring the nature of Nigerian construction industry, gap of BPM and new production model concept; (ii) investigating the awareness and application of the new production model concept as a method for enhancing the performance of BCFs in the study area. To accomplish the aforementioned aim, a research method comprised of a literature review and questionnaire surveys was designed to address the objectives. The study identified unproductive/ineffective BPM, lack of buildability and maintainability analysis, professionalism mismatch, and unauthorized practices as the gap of BPM. This study revealed that the gap of BPM is the main reason behind building failures/collapses, bad debts, low productivity, low level of clients satisfaction, high labour turnovers, and barriers to economic fortune. The study also revealed poor cash flow, lack of experience in the construction field, unprofessionalism and a high number of unskilled employees in a company, lack of co-operation from subcontractors and suppliers and poor labour relations, as the top five causes of BPM gap. BCFs in Nigeria have adopted several approaches to arrest these issues, but the challenges still occur. Thus, the new production model concept that has not been well adopted by construction firms in Nigeria, and which emphasizes on-site production, and aims at enhancing production management is a key to tackling these issues. Based on the survey findings, the study recommended that the issue of the gap of BPM must be correctly identified and clearly understood so as to enable BCFs to bridge the production management gap which will influence their performance positively.","PeriodicalId":53274,"journal":{"name":"Journal of Engineering Project and Production Management","volume":"10 1","pages":"50 - 63"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48969123","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}

Off the shelf software, MinitabTM was used to generate the control charts based on earned value and planned value. While this paper proves that the Laney U chart, with correct interpretation, acts as an effective trigger-based tool for schedule risk management, it also generates further avenues for research into similar use of control charts for cost performance and other quality indices.","PeriodicalId":53274,"journal":{"name":"Journal of Engineering Project and Production Management","volume":"10 1","pages":"35 - 41"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41879028","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 study adopted the pragmatism research paradigm, with a cross-sectional survey design. Census was used to select 187 respondents from a target population of 187 functional members of staff in fibre optic infrastructure departments of two mobile telecommunication and four internet service companies in Nairobi County, Kenya. A self-administered structured questionnaire was used to collect quantitative data while an interview guide and document review guide were used to collect qualitative data. Inferential statistical analysis was performed using multiple regression. It was demonstrated that leadership skills and stakeholder management act together to have a significant positive influence on the execution of fibre optic infrastructure. Therefore, there is a need for companies to ensure that stakeholders are involved in all phases of a project from inception to closure. Mobile telecommunication and internet service providing companies should also develop training programs to improve the leadership skills of project leaders and make use of conflict management strategies and communication skills to ensure appropriate management of change. It was suggested that similar and comparable studies should be conducted in other countries across the world.","PeriodicalId":53274,"journal":{"name":"Journal of Engineering Project and Production Management","volume":"10 1","pages":"80 - 86"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42400505","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}

However, indigenous construction firms compete with their multinational counterparts for the available skilled workforce. The study, therefore, investigates the level of project managers’ skills acquisition in indigenous and multinational construction firms in Lagos State, Nigeria. The study adopted cross-sectional survey research and data were collected using a structured questionnaire. One hundred and thirty-three questionnaires (106 indigenous and 27 multinational) were administered to project managers and 106 retrieved and valid for analysis representing 73% response rate. The techniques for analysing the data are mean score and t-test. The study revealed that the most important skill type as perceived by project managers is a technical skill and there is no significant difference in the level of skill acquisition by project managers in indigenous and multinational construction firms. Hence, the study concludes that the categorisation of construction firms has no effect on the level of skills acquisition by project managers; therefore, it plays no role in project managers’ skills acquisition. Project managers should strive towards developing themselves through training for improved performance and for successful completion of construction projects.","PeriodicalId":53274,"journal":{"name":"Journal of Engineering Project and Production Management","volume":"10 1","pages":"71 - 79"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43826422","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}
