  1. List the 3 types of resource that can form part of the cost to complete a task on a building project. How does the term ‘all-in-rate’ relate to this?
  • Personnel: Employees of the company contracted to carry out the works.
  • Materials: Any material required to construct the project.
  • Plant & Equipment: Specialist plant and equipment needs to be taken into consideration for the work plan.

The term ‘all-in-rate’ relates to this in a way that it involves the total cost of an item, including all direct and indirect costs for that item. These costs would include labour rates.

  1. At the time of tendering, quotations are sought from many suppliers and sub-contractors. Generally builders are looking for the most competitive price but performance and other criteria are also a factor in the selection process. Explain why the nominated supplier and sub-contractor details need to be included in schedules.

Nominated supplier and sub-contractor details should be included in schedules as they are important when it comes time to preparing purchase orders. It is also important, as it will show what materials the sub-contractor may provide, so that the builder does not order the same thing. They are important for preparing the address section of purchase orders.

  1. Take off and measure the quantity of face bricks required for the project, including wastage. (Note that Q5 requires you to cost the bricklayer trade in total, so keep this in mind in your take off.) Use a standard P10 format (see attached form) to determine the quantity.

(10 marks)

Prepare an order form from your building company for the supply and delivery of these face bricks to your project. Include all relevant details to ensure the order is received on site when required. Use fictitious names and addresses to form your order. (Note: MS Office Word has sample templates for Purchase Orders that you may wish to use)

  1. When a tender to build a project is won, the estimate (or builder’s bill) becomes the ‘budget’ for the project. Estimated costs have to be achieved or savings made in other areas to produce the anticipated profit margin. The actual costs of a project are usually recorded in a ‘Job Cost’ document and compared to the estimated costs. This is usually done on a trade by trade basis.

Prepare a simple job cost analysis sheet for the trade of Bricklayer for Project 1. Take off and measure the entire trade of Bricklayer and cost each item. Include the actual cost of each item and show the variance on estimated to actual costs. (You can make up some numbers to show a variance)
(Your ‘items’ should include; face bricks, commons, mortar, flashings, veneer ties, lintels, cleaning down, labour, as a minimum. Use the following as headings for your cost analysis sheet: Item, Details, Est. Cost, Actual Cost, Variance)
