TAKING OFF PROCESSES AND PREPARATION OF AN UN-PRICED BILL OF QUANTITIES

ABSTRACT

Class work alone on measurement of building work is not enough to equipped the student with the required knowledge and skill required on the measurement of building work, in accordance with standard procedure laid down by BESMM3(Building & Engineering Standard Method of Measurement). It is against this background that the introduction of project work was introduce to expose the student to practical and theoretical method of taking off of building work apart from class work so as to increase their skill and knowledge in addition to class work.

The chapter one of this project demonstrate the aims, objectives of this research and the scope and limitation while the chapter two and three represent a literature review on the procedure of measurement of building work in order to have a better understanding of taking off, abstracting and billing processes prepared in chapter four for the proposed four (4) bedroom fully detached duplex.
