Unique Lower Embodied Carbon GRP Permanent Formwork
Devon County Council worked in partnership with Teignbridge District Council to manage the design and construction of a new 26m span bridge and section of 110m of carriageway west of the A379 within the Shutterton area of Dawlish in Devon.
The new link road and an associated bridge over Shutterton Brook is part of a scheme connecting an 860-home housing development to the A379. The council’s aim for the road was to prevent traffic and avoid having to use Elm Grove Road and going past two schools.
Devon County Council appointed Montel Civil Engineering as the main contractor for the work which began in August 2023 and was completed in November 2024. Montel Civil Engineering is a collaborative, experienced and successful privately owned civil engineering company, with extensive experience in delivering complex civil engineering projects up to £20 million, within both the public and private sectors. As a principal contractor, Montel Civil Engineering planned, managed and delivered the Dawlish Bridge project on behalf of DCC.
Montel chose Mekina Industries to supply its Mek-Dek panels as the GRP permanent formwork panels for the project. Mekina’s unique lower embodied carbon GRP Permanent Formwork panels undergo a quality manufacturing process that guarantees uniformity, strength, and structural integrity in the end product. As a leave in place solution that is added prior to the concrete pour, it is not participating, (i.e. it does not contribute anything to the load-carrying capacity of the concrete, but offers a durable solution which also offers an attractive underside surface to form a soffit when viewed from underneath the bridge structure.
The bridge was designed to be permeable to bats, which was achieved with a clear span design, which provided sufficient headroom through which bats can fly. Interestingly, the decision was taken for no lighting on the bridge, to avoid deterring bats from flying along the brook and beneath the bridge. Adding further support for the sustainability aims of the project, mammal and dormice features were be incorporated beneath the bridge to provide safe passage along the brook.
