Set in the woods of Kirkintilloch, Mossfinan Bridge is a masonry arch bridge that is no longer fit for purpose. Our Glasgow based teams were tasked with assessing the strength of the bridge and thus design a suitable replacement for the inadequate structure. The client, East Dunbartonshire Council wanted any such design to be in-keeping with the rural characteristics of the surrounding area and a minimal disruption period during construction was a must.
Our experts carried out a detailed assessment of the bridge and found it could only take an insufficient 15 Ton load. A detailed site investigation was also carried out, including a flood assessment of the area and an ecological survey that would aid any design to surpass minimum requirements. Having gauged the expertise of our Edinburgh based bridges, highways, water, environmental and geotechnical teams; we subsequently produced multiple designs with innovation at the forefront.
The idea that caught the client’s eye was a Flexi-Arch bridge design, which will drastically reduce construction time and minimise operations over the adjacent river bed. Taking only a day for installation, the ground-breaking method couples random stone cladding and dry stone masonry parapets, providing a solid and safe base for follow-on works. The council was happy to invest in the superior bridge type and our project team are now working on final design options before undertaking site supervision in 2018.
