Copperhouse Sluice
KGAL has been commissioned by A&T Services on behalf of the Environment Agency to initially carry out
a design options study for designing a method of supporting the vertical lift gate at Copperhouse Sluice,
in case the existing single rope drive arrangement fails.
The gate, located in the popular tourist destination
of Hayle, Cornwall, is used to control ýows from
Copperhouse Pool to the sea. However, the gate
channel is easily accessible to the general public
at low tide and the Environment Agency has raised
safety concerns over possible rope failure when
personnel are under the gate.
Subsequent to the submission of the KGAL design
options report and meeting with the Client Team, a
preferred design option was chosen, enabling
KGAL to now proceed to the next phase, the
detailed design.
A site survey was recently successfully carried out
by Jasper Taylor and Matt Hockham to conürm
existing dimensions on site, as well as sampling the
local Cornish pasties and ice creams!
Jesson and Grand Re-doubt Outfalls
KGAL was commissioned by Ardent Consulting Engineers on behalf of Jackson Civils and the
Environment Agency to produce a condition report and outline design package for replacing the
existing pointing doors at Jesson Outfall (Dymchurch) with composite stainless/HDPE ýap gates.

In addition, the scope included a condition survey and design package for
re-designing the seals on the existing ýap gates at Grand Re-doubt Outfall
(Dymchurch), as the Environment Agency had reported that the existing
seals had been regularly failing/falling oû in the ýows.
Site surveys were successfully carried out at both sites by Jasper Taylor in
May 2023, enabling the production of condition reports, 3D models/drawings
and design speciücations for the two sites. The ünal packages were
submitted to Jackson Civils and the EA in July 2023.

Of personal interest to Jasper, the Jesson Outfall had been previously worked
on in the 1950s by his Late Grandfather (J.I.Taylor M.B.E., B.Sc., M.I.C.E.,
Engineer to the Board), who at that time was Chief Engineer for Kent
Waterways and was shown as checker on the Jesson Outfall historic drawings.
