Item EFFICIENT UTILISATION OF AUTOMATION IN CONSTRUCTION MATERIALSHANDLING PROCESSES(Acta Structilia 2022, 2022-12) Alumbugu, Polycarp Olaku Winston Shakantu Abel Tsado & Wasiu Ola-awoThere is a limited understanding of automation in construction materials-handling processes utilised by manufacturing firms in Nigeria. This article evaluates the level of utilisation of automation in construction materials-handling operations by manufacturing firms in North-Central Nigeria, to improve operational efficiency and reduce operating costs. Using a case study research design, quantitative data (observation guide with measurements) were collected from 32 purposively selected constructionmaterial manufacturers. A total of 72 customers’ orders were observed and recorded to be representative of deliveries from the sampled (n=32) manufacturers’ warehouses to other terminals. The descriptive method of data analysis was employed using percentages and results presented in a form of bar charts. The study reveals low-level utilisation of automation in the combined processes of order picking, storage, loading, and offloading of material. These imply increasing material costs and causing a delay in delivery. The article concludes by providing construction-material manufacturers with areas that require automation to optimise material-handling operations. A recommendation is made for further study to explore why automation is not utilised despite its advantage.Item Assessing construction material manufacturers’ warehouse processes from a customer satisfaction perspective(Journal of Transport and Supply Chain Management, 2021-03-25) Alumbugu, Polycarp Olaku Winston W.M. Shakantu Ibrahim SaiduBackground: The objective of warehouse processes is to satisfy customer’s desires and requirements whilst using house, equipment and labour effectively. However, in Nigeria studies have revealed operational problems in warehousing and a lack of customer satisfaction in the delivery of construction materials. Objectives: The aim of this study was to evaluate the level of customer satisfaction with the delivery of construction material from the manufacturers’ warehouses to customers or other terminals, with a view to improving the operations. Method: This article adopted a case study research design method in which quantitative data were collected and analysed. The target population was the North-Central geo-political zone of Nigeria. A total of 32 construction material manufacturers were purposively selected from the zone. The observation and measurement approaches were adopted for data collection. A total of 72 customers’ orders were observed and recorded to be representative of deliveries from the sampled (n = 32) manufacturers’ warehouses to other terminals. A customer quintile benchmark metric was also adopted for analysis and for comparing field results with best practices. Results: The findings revealed that the involved construction material manufacturers’ warehouse processes, were suboptimal and ineffective in terms of perfect order completion and total order cycle time. These results indicated major opportunities for improvement. Conclusion: This article concludes with providing construction material manufacturers with information about their warehouse processes that might help to ensure that the construction material arrives at its final destination in optimal quality, time and cost.Item Analysis of Outbound Logistics Channels for Construction Material(Journal of Engineering, Project, and Production Management, 2019-10-13) Alumbugu Polycarp Olaku , Winston W. M. Shakantu , & Abel John TsadoOutbound logistics channels are of crucial importance for an efficient construction materials logistics management and impacts on customer satisfaction. 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
