Abstract:
Material waste is made up of unwanted materials generated during construction, such
as rejected structures and materials, materials that have been over ordered or are surplus
to requirements, and materials that have been used and discarded. In Ghana, between
5% and 27% of the materials acquired for construction projects are wasted. Ghana's
construction business finds it challenging to compete globally due to the current free
global economic order. The study sought to assess material waste minimisation at the
construction phase of a building project through the implementation of lean
construction principles. The objectives of the study include; to assess the level of
contribution of some waste minimization measures to waste reduction in the Ghanaian
construction industry, to determine the level of understanding of the lean concept
among construction practitioners in Ghana, and to determine the obstacles to successful
lean construction implementation in the Ghanaian construction industry. Quantitative
was used as the research design. A questionnaire survey was adapted to get feedback
on the opinions of respondents about the wastage of building materials and the
implementation of lean principles in the Ghanaian construction industry. The study
adopted a census approach in the first stage in which the population of D1K1
contractors operating in the study area was determined. In the second stage, systematic
random sampling was adopted to select the construction professionals covered in the
survey using the sampling frame compiled for the list of professionals. Out of the total
construction professional population of 105 in the study area, 83 of them representing
79.05% were chosen as the sample size for the study. The findings from the study
revealed that purchasing just enough raw materials, using materials before they expire,
good coordination between store and construction personnel to avoid overordering,
using more efficient construction equipment, and using proper site management
