An ornamental Chinese footbridge, originally designed in 1899 for Dumfries House in Scotland but never built, has finally been installed. The original drawing was submitted by Scottish architect Robert Weir Schultz, a friend of the 3rd Marquis at the time.
The new bridge would have to look as close as possible to the fineness of the original drawing but also meet modern structural standards.
There was also a tight timescale as the bridge had to be ready for the visit of Prince Charles, the patron of Dumfries House.
CTS Bridges was appointed to undertake fabrication modelling, manufacture, delivery and installation of the bespoke three span bridge which is a way over the Lugar Water on the estate.
CTS recreated a structure to modern design whilst keeping the style of the original drawing. Due to the large deflections in service, CTS advised pre-sets of the structure were defined to allow CTS to create a structure which maintained the true geometry in-situ. Limitations with the current design were discussed, with CTS drawing on their own structural and manufacturing experience to advise alternatives.
The time-frame for delivery was a challenge. A detailed plan was delivered to ensure that all the components of the bridge came together at the right time. Sequencing of the fabrication considered the lead time of each and every element to mitigate any delay to the fabrication process.
CTS successfully delivered the bridge to site. The decorative canopy was manufactured by Jonny Briggs Joinery under a separate contract and, once in place, the Chinese Bridge was complete on time for the Royal visit.
