Ferry Village Marina

Background:

Plans for a prestigious housing development on the banks of the River Clyde necessitated the demolition of a former shipbuilding yard, together with the removal of concrete slipways and timber dolphins. The follow-on civil engineering works required us to crush demolition materials, import aggregates and to upfill the entire site to comply with designated 200-year flood prevention levels.

Challenges:

• The programme of works would be dependent upon tidal levels
• Excavation and removal of abnormal below-ground structures
• Cutting away and removing timber dolphins
• Breaking out, removal and infilling of concrete slipways
• Crushing, laying and compacting uphill materials to design levels.

Solutions:

Demolishing this partially submerged structure presented considerable logistical challenges and required meticulous planning and organisation.

1. Specialist demolition equipment was employed to carry out the demolition of all existing above-ground structures. Suitable materials were processed and stockpiled on site for a follow-on crushing operation.
2. Unsuitable debris was removed off site.
3. A comprehensive site investigation was carried out to a depth of 3m to identify and remove any unrecorded, historical foundations and below ground structures. Once more suitable excavated material was processed and stockpiled for crushing.
4. The removal of decaying, partially collapsed, timber dolphins at low tide to ensure safe execution of operations.
5. An on-site crushing operation was established and previously processed material was crushed to produce a 6F2 specification.
6. The crushed materials were layered and compacted over the entire site until the specified finished levels were achieved. 

The site was made ready in good time for construction to commence on the new housing development.
