Advanced Professional Certificate in construction (City and Guilds)
Unit 8: Estimating and costing of construction - Level 3
Unit Summary
This unit concerns the knowledge and skills required to demonstrate an understanding of:
- the mathematical skills and processes needed to complete measurement and produce calculations related to the costing of labour, plant and materials, required for construction work
- the components of bills of quantities, their purpose, use and relationship with standard methods of measurement
- estimating and quantity surveying practices used in the construction industry
- how quantities of measured work are converted into a tender for building and civil engineering schemes.
This unit is divided into four outcomes which may be studied separately. Alternatively you may use occupational evidence for accreditation of each outcome, separately or collectively.
Aims
This unit aims to enable the candidate to:
- acquire basic skills and procedural knowledge for quantifying and estimating the cost of building and civil engineering work
- gain a working knowledge of the documents and proformas used in quantifying and estimating the cost of building and civil engineering work within a vocational context.
Outcomes
On successful completion of the unit the candidate will be able to:
- select and use formulae for the calculation of length, area, volume, capacity, mass and number and present answers to an appropriate degree of accuracy
- use price books, electronic data-bases and schedules of work outputs to produce calculations of unit rates in accordance with current practice and explain how the estimating function is organised
- reference work items to standard items contained in the current Standard Method of Measurement for Building Work and the Civil Engineering Standard Method of Measurement
- complete representative sections of a bill of quantities and estimate the cost of building and civil engineering work from supplied information.
Assessment
The outcomes of this unit will be assessed on the production of a portfolio of work produced from supplied drawings and other information, demonstrating an ability to
- quantify work by measurement,
- reference work to standard items suitable for insertion in a bill of quantities,
- allocate resources required to complete standard items of work,
- estimate unit rates for standard items of work,
- complete a tender summary form.
The portfolio must contain standard pro-forma (taking-off sheets, billing sheets), pricing notes, unit rate build-ups, cost estimates, calculations and a tender summary form for representative sections of building and civil engineering work.
