Guidance Information
1 Definitions
Project requirements are the requirements of the project as set out in the tender documentation.
Trade sections are a breakdown of individual trades involved in a building project, outlining their input into the construction of a building.
A schedule of quantities is a list of building work items with quantities set beside them.
Small buildings are small scale, light weight buildings, generally of non-specific design, and of domestic scale with lightweight framing and/or concrete or concrete masonry construction.
2 Estimating at this level is limited to construction of a small building.
3 Estimating at this level covers the build up of costings and prices for tendering purposes.
4 All activities must comply with any policies, procedures, and requirements of the organisation/s involved; the ethical codes of relevant professional bodies; and any relevant legislative and/or regulatory requirements.
5 Legislation and publications relevant to this unit standard include: Health and Safety in Employment Act 1992 and Health and Safety in Employment Regulations 1995;
Building Act 2004;
NZS 4202:1995 Standard method of measurement of building works, available from Standards New Zealand ().

Explain the role of the schedule of quantities in preparing a tender submission for a small building project.
Performance criteria
1.1 Trade sections of a schedule of quantities are explained in relation to main contractor and subcontractor costs and responsibilities.
1.2 The preliminary and general section of a schedule of quantities is explained in relation to main contractor and subcontractor costs and responsibilities.
Outcome 2
Build up unit rates for measured items from specific schedule of quantity trade sections for a small building.
Range excavation, concrete work, reinforcing steel, brickwork, blockwork, metal windows and doors, carpentry, joinery, roofing, plasterboard linings, floor coverings, glazing.
Performance criteria
2.1 Measured items are separated into pricing components.
Range labour, materials, plant, on site overheads, off site overheads, profit.
2.2 Labour, materials, and related measurement items are selected and applied to these components to build up unit rates.
Outcome 3
Obtain and use material and equipment quotations for a small building.
Performance criteria
3.1 Market rates of materials and equipment are investigated in terms of cost, availability, and conditions of sale or hire.
3.2 Quotations are obtained from suppliers.
3.3 Quotations are assessed against, and selected to meet, project requirements.
Outcome 4
Apply overheads, profit, and on-cost items to built-up unit rates for a small building.
Performance criteria
4.1 The principles of overheads, profit requirements, and on-cost items are classified and explained in terms of total trade costs.
4.2 These principles are used in the formation of built-up unit rates.
Outcome 5
Collate all priced components into a tender submission for a small building.
Performance criteria
5.1 Priced items, trade totals, and a lump sum for preliminary and general work are collated to contribute to a tender submission in accordance with tender and contract conditions.
