11 In Hunter Development Brokerage Pty Ltd v The Cessnock City Council; Tovedale Pty Ltd v the Shoalhaven City Council [2005] NSWCA 169, (2005) 63 NSWLR 124, a test was set out to determine whether work done in preparation for a development can be considered to constitute physical commencement. Tobias JA adopted the meaning of the word "engineering" in the Macquarie Dictionary being: "The art or science of making practical application of the knowledge of pure sciences such as physics, chemistry, biology etcetera". His Honour said at [83]-[88]:
"83 In my opinion, the expression 'engineering work' in its context of forming part of the composite phrase 'building, engineering or construction work', should be given a broad meaning to include all those activities associated with, and forming a necessary part of, the discipline of engineering applicable to the subdivision of land. There can be no doubt that engineering as such can involve many different elements: relevantly with respect to a subdivision, it involves civil engineering work such as the design and (possibly) the construction of roads, sewerage systems, drainage and the like.
