Bill of Material and Labour Template for Construction Information Management

Abstract

Information and Communication Technology advancement has made the method of practice across different industries and businesses record fundamental changes in various dimensions and levels. The construction industry is determined to measure up with other industries in this and has since embraced the use of computer software to perform most, if not all of its activities. It is generally known that this software is not cheap and they require special skill to use. This research study is aimed at developing a computerised template for material and labour schedules for some selected items of work in construction using Microsoft Excel. This is an inexpensive way of estimating to save cost while eliminating the traditional method. The study adopted a mixed research method that involved observation of labourers on-site and validation through a questionnaire survey. The personal observation was carried out and labour outputs were recorded which was used together with material constants in developing the bill of material and labour template. The template was validated by practising Quantity Surveyors for ongoing projects and an average of 92% accuracy was recorded. It was concluded that the template can enhance the accuracy of Quantity Surveyors’ estimate of materials and labour for construction projects.
