Effektivare materialhantering från leveransmottagning till materialanvändning på en byggarbetsplats

Sammanfattning: Purpose: The problem with the construction industry is inefficient material handling that creates waste in form of unnecessary activities that do not increase the value of the product. The construction industry is accused of production delays, exceedance of budget and difficulties in having a high quality. The aim is to find opportunities for improvements to make the material handling on a construction site at deliveries, material storage and material transports more efficient. Method: A qualitative case study of an organisation was carried out to achieve the aim of the report. The methods used in this study was unstructured observations, semi structured interviews and document analysis. Findings: A checklist for material handling based on the theories of Muda, 5S and JIT within Lean has been designed as an improvement and is intended to be used at a construction site. The checklist is based on the collected empirical study and consists of three parts, based on the issues of the study, which were deliveries, material storage and material transport. The purpose of the checklist is to improve the material handling at a construction site by identifying and eliminating wastes in terms of waiting, transport, storage and defects. Implications: By using the checklist, follow the delivery plan, improve the construction site plan and improve the contract between the suppliers and the company that have been concluded from the study result, waste in deliveries, material storage and material transport can be reduced. The recommendation is to follow the suggestions for improvement to make the material handling more efficient and reduce waste on a construction site. Limitations: The limitations that have been made in the study is to identify the wastes in the material handling moments that have been used in the study during the different material handling processes. The communication between workers, in what way the company plans their work activities, work environment and quality of work is not included in the study.
