What is being bought
The general requirement is for targeted marine surveys of 5 specific areas (see map) between Aldeburgh (East Suffolk) and Pegwell Bay (Kent), to supplement a survey of the whole route undertaken in 2021, to inform of seabed morphology and shallow sediment structure, and to provide benthic characterisation and habitat maps. The PQQ process is to establish market capability to carry out the required works within the time period indicated. It is the Client's intent to follow up the PQQ responses with a tendering process with a view to award a Marine Seabed Survey contract based on a detailed RFP process. The survey scope of work covers geophysical, geotechnical and environmental sampling. In addition to the 5 survey areas, the scope of work may potentially include an additional offshoot survey of the main route in the near future.
