Steps for preparing materials list
There are several steps in preparing this list.
Step 1: Decide what is needed
Firstly, you need to thoroughly read through the site files (including the drawings and specifications) to work out the required materials. Are any special materials (eg imported floor coverings) or fixtures required? If so, you will need to allow additional time to order these in.
Step 2: Prefab or construct on-site?
Decide how to purchase the materials. There are two options:
- Purchase materials for construction on-site, eg timber for on-site framing.
- Purchase prefabricated components, eg wall frames, roof trusses.
Today most builders purchase pre-made wall frames and roof trusses because it speeds up work time on-site.
Step 3: Work out quantities
Work out the amount of material needed. You can do this by looking at the measurements on the plans and using these to calculate the various lengths required.
This information can also be found from lists like a 'timber list' provided by the estimator as part of the tender for the project. This is the most efficient way for a building company to operate as it uses information already available.
If the builder is using a computer program for projects, this will also include the estimating requirements. It is then very simple to make the estimates into a request to quote and from there into an order. A building software system such as 'Databuild' has these work requests built into its program. Many building materials suppliers have Databuild as part of their office package and can receive a request to quote from a builder, prepare a quote and email this back to the builder.
