The Principal Designer role will be undertaken by Savills plc. The estimated value of the contract is approx.

The deadline for tender submission is 18 December 2020 at 12 p.m. with award of contract following on 26 January 2021. The works period is significantly constrained by bird migration and breeding patterns meaning that works may only commence from mid/late March 2021 and must be complete by mid May 2021. However it should be noted that this works period may be subject to review and as such the Council will require flexibility from the appointed contractor in the event that these dates need to be moved forward or backwards. The services of a specialist ground investigation contractor are required to undertake specialist intrusive marine ground investigation survey required to inform the proposed development. Specifically, the GI works are required to provide information to support design of the proposed reclamation infilling; design of the perimeter River Wall; support the design of the proposed Horsea Island Bridge; and assessment of sediment quality and composition of proposed dredging operations. The ground investigation will comprise overwater investigations and will be carried in the following order: 1) Tipner West Land Reclamation; 2) Tipner to Horsea Bridge Link; 3) Quay Wall Replacement; 4) Dredged Channel; 5) Horsea Foreshore. The works are to be undertaken predominately on the Intertidal Zone and within the existing SSSI and SPA. As such all works will therefore need to be undertaken in a highly controlled manner to avoid impacts to Marine Ecology. An MMO application for the GI Works is currently being undertaken by a Marine Projects. In addition to general investigation activities as stated within the specification the scope of the appointment will also cover the following: • onsite inspection and logging of samples; • in-situ testing in boreholes; • chemical and geotechnical sampling in exploratory holes; • laboratory geotechnical testing of soils and rock and chemical testing of soil and groundwater samples; and • UXO survey of all overwater exploratory holes.
