J. & G. Rennie
On the death of his father in 1821 he entered into partnership with his younger brother John, as J. and G. Rennie, and for many years they were engaged in completing the vast undertakings originated by the elder Rennie. John concentrated on the civil engineering portion of the business, whereas George supervised the mechanical engineering. Nevertheless, about 1826 he was entrusted with the construction of the Grosvenor Bridge (Chester) over the Dee at Chester, from the designs of Harrison.
In 1830, they were involved in the construction of George Stephenson's Liverpool and Manchester Railway. He had considerable practice as a railway engineer, and made plans for lines to connect Birmingham and Liverpool, the Vale of Clwyd line, the railway from Mons to Manege, and the Namur and Liege railway, of which he was appointed chief engineer in 1846.
