The £1.2 Mamhead Slipway was funded by the East Devon District Council as a larger more practical alternative to the existing slipway on the River Exe, which would bring more maritime business to the area. The old slipway, originally closed for public safety, was demolished early in the year before contractors Raymond Brown had to work agains the clock to build the new onw before the migrating birds arrived in the Autumn. A special license to work on the estuary, home to thousands of migrating bird species from the arctic was only granted for the summer season.
Scope of Works
Initally long reach machines were required to break out the slipway and remove obstructions in advance of piling works. Later further excavation works were needed as piling progressed, the profilling of the slipway and cofferdam excavation were also then required.
WM Plant Hire supplied their CAT 349 long reach excavator fitted with the latest tier 4 technology, well capable of handling heavier marine applications and fitted with specialist underwater breaker, for breaking out the slipway and removing obstructions prior to piling. A Case CX210 machine was then used for reprofiling and cofferdam excavation works. The marine experience of our operators proved a real asset to working in the challenging tidal environment and keeping on programme.
