Aarsleff Ground Engineering were awarded the contract by WW Martin Ltd to design & install 436 linear meters of sheet pile retaining wall for a new housing development off Hailsham Road in Herstmonceux, East Sussex.
Aarsleff are now on site & have taken delivery of over 100t of the 550t total requirement.
AGE main works will provide a wall with retained heights up to 6m to accommodate the existing sloping site & allow the housing development to be constructed behind.
WW Martin constructed a temporary piling platform for the AGE 80 tonne crawler crane to operate from & allows AGE to install pairs of Z piles using temporary guide frames as support until s
ufficient penetration in to the Wadhurst clay strata is achieved. A crane suspended high frequency vibro hammer is being utilised to install the Z- piles & the remaining 133 No. 7m long GU8N sheet piles will be installed with Aarsleff’s own Movax SG75 & Volvo base machine.
Aarsleff will be installing almost a full range of Z profiles for this project, with section lengths ranging from 9.5m to 17m long to accommodate the site’s varying retained heights from 2m to 6m.
Aarsleff Ground Engineering mobilised work on 11th June and are expected to be on site for approximately 6 / 8 weeks.
