Unit 10 Measurement & Estimating Assignment Brief

Introduction

The techniques explored in this unit are essential skills in maintaining the competitive position of a construction firm in obtaining work through the procurement routes of construction. Mastering the skills of measurement and estimating is essential for the quantity surveyor and estimator.
The overall aim of this unit is to give students an understanding of the quantity surveying techniques of measurement and the estimation of rates for the compilation of tender information. This is a vital activity in achieving a successful outcome for a contracting company in tendering and winning work.

Topics included in this unit are: estimating techniques; standard methods of measurement; taking- off dimensions; preparation of bills of quantities; estimating data collection; the assembly of an estimate for a work package.

On successful completion of this unit, students will be in a position to take- off quantities from drawn information and to prepare estimates for work packages. Students will have the fundamental knowledge and skills needed to progress to a higher level of study.

Learning Outcomes

By the end of this unit, students will be able to:

LO1 Define standard measurement techniques used for taking-off quantities for estimating purposes

LO2 Perform taking-off techniques in the production of a range of quantities for  a structure

LO3 Interpret the principles and techniques of estimating in compiling a final price

LO4 Prepare an estimate for a work activity.
