Longrock Coastal Protection Penzance Stage 2 Hire of Operated Plant

Tender description

The hire of an Amphibious excavator (22-30t) with Trailer Barge and Tree Shear Attachment for an approx. duration of 3-4no. months - indicative hire commencement/delivery date Sept' 2019. The hire of a suitable rescue boat sufficient for the number of personnel on-site. Hire period, as above. The operated plant shall be utilised to carry out improvement works in a marsh to create additional open water channels. The plant will be carrying out works in marsh conditions in a RSPB nature reserve and SSSI. The works will consist of excavating/dredging approx. 4,500m3 of reed bed/silt over 2,200m2 to form 2m deep open water channels and depositing the excavated material in formed bunds 1-1.5m high adjacent to the newly formed channels on top of existing reed bed. The machine will also be used for clearing to ground level approx. 1,200m2 of trees located within the existing reed bed, approx. 2,000m2 of existing willow woodland and 3,700m2 of reed bed which will enable the excavated material to be placed. A topographical survey was undertaken in February of 2018, and indicates a clear water depth in the area of the open water channels of between 100-200mm. However, the ground below this is very soft, and the marsh is subject to tidal variations, which on a normal high tide could raise the water level be approximately 300mm. Cormac are seeking to initially shortlist a tenderer based on most competitive rates and ability to provide all equipment required and suitably experienced operators. It is our intention to work with the shortlisted tenderer to develop an appropriate methodology and programme of works, prior to formal award.
