  • Input benchmark – plasterboard installation

    The main activities for businesses in this industry are fixing and finishing of plasterboard sheets for buildings and other structures. The major products and services provided by plasterboard installers include the installation of plasterboard, cornices and ceiling roses.

    These benchmarks do not apply to businesses providing solid or wet plastering, decorative plaster finishing and cement rendering of buildings.

    You may find the input benchmarks useful in calculating the expected income based on the labour and materials used. They apply to plasterboard installers who purchase their own materials and work directly with household customers.

    The benchmarks have been developed with advice from the Association of Wall and Ceiling Industries of Australia and New Zealand Inc (AWCI) and trade participants.

    They represent the industry norm. You should consider your own personal circumstances when using the input benchmarks to assess your situation.

    Note: These benchmarks are current as at April 2015.

    Input benchmark guide

    The table below sets out input benchmarks for plasterboard installers. It is not relevant to plasterers who do solid plastering.

    You can use this benchmark to compare and check your business performance to the plasterboard installation industry average.

    Input benchmark plasterboard installation examples

    Example 1

    Samuel runs a plasterboard installation business and has one subcontractor working for him. They work on household jobs only.

    Samuel normally charges $20 per square metre for supply and installation of basic plasterboard and $5 per linear metre for cornice. Samuel reviews the statements from his supplier which show that he has purchased 9,800 square metres of plasterboard, allowing for 5% wastage he determines that he installed 9,310 square metres of plasterboard. His records show 3,200 linear metres of cornice installed.

    As his supply and installation charges are consistent with the benchmarks, he uses the benchmark guide to calculate that his total sales should have been $202,200.

    Samuel's records show reported income of $201,000, which is within the benchmarks and close to his estimate. This leaves him confident in his record keeping.

    Example 2

    Karen has a plasterboard business and uses a three person crew on each job. She installs only. Karen normally charges $15 per square metre for plasterboard and $5 per linear metre for cornice. Her crew can install 180 square metres of plasterboard and 60 linear metres of cornice every three days to earn $3,000 ($1,000 per day). This is close to the installation rate benchmark.

    Checking her business records, Karen finds she has recorded income of $160,000 for the year. Using her benchmark earnings of $1,000 per day, Karen estimates she would have worked 160 days to earn $160,000. However Karen has had a busy year and is sure she worked more than that.

    She reviews her quote books and finds 20 jobs where she was paid cash and she charged $60,000 for these jobs. With these additional jobs, Karen calculates that she worked for about 220 days and she recalculates her income for the year at $220,000 which is consistent with the benchmarks.

    Karen asks her bookkeeper for advice on keeping better records.
