David Lennox oversaw the construction of the Liverpool Dam, one of the first engineered weirs built in New South Wales, which supplied water to the town and served as a causeway across Georges River. The Weir was constructed under the supervision of Captain Christie of the 80th Regiment, assistant engineer and superintendent of iron gangs in the Town of Liverpool. 

The second record of brick making is in connection with the building of the Duck Creek Bridge 1833-1836. The bridge previous to this was a pioneer log type and was burned down during a bush fire. A temporary bridge was built a little further down the creek. The builders were Bob Gooch and Bill Burch two famous builders from Parramatta. Robert Goch was a noted bricklayer and contract builder; he built the Darling Mills in Parramatta North. The bricks were made from a pit on the south east side of the bridge between the creek and Clyde Street, Sydney Road. The bridge designed by Lennox was opened by Governor Richard Bourke in January 1836. While the arch is still visible, the structure of the bridge has been altered when the Sydney Road (now Parramatta Road) was widened.
