Ralph Beattie Bosworth is a long established Quantity Surveying practice which commenced in Perth, Western Australia, in 1968. The practice was the result of the partnership of its founding directors, Peter Ralph and Hunter Beattie. In 1979 the partnership was joined by Bill Bosworth, the third of the directors that lend the practice its present name.

In 1981 the Sydney office was established by Bill Bosworth and by the mid eighties Ralph Beattie Bosworth had expanded to a truly Australia wide practice with further offices in Melbourne, Brisbane, the Gold Coast and Darwin.

The eighties saw the practice change from a medium sized Quantity Surveying firm in Perth to Western Australia's largest Quantity Surveying and Construction Cost Consultancy, with offices throughout Australia.
