Beccles Yacht station maintenance dredging

Descriptions

The removal of accumulated sediment and organic detritus from the Beccles Yacht Station and boat dyke to a depth of -1.5m ODN. It can be assumed that Chart Datum is the same or similar to ODN. The Yacht station measures approximately 40 x 165metres, whilst the boat dyke is 10 x 170metres. Based on the bathymetric survey, at least 3,300m3 of sediment requires to be removed to achieve the target depth. It should be noted that the river Waveney is a tidal river. We anticipate the dredging methodology will involve a bank-based long-reach excavator and dumpers to transport the arising dredged material to the recovery site. Other methodologies will be appraised. It is anticipated the waste recovery will involve reusing the arising sediment on the land available to the north and northeast (TM 42473 91149). Involving stripping of the topsoil and creation of bunds to contain the dredged material. Dredged material is to be mixed with topsoil to create a new topsoil that will be spread, prepared and seeded for a wildflower meadow. Subject to licencing, when granted, there is a requirement for maintenance dredging and waste recovery at Beccles Yacht Station. The start date is subject to licencing, anticipated end February 2021. We propose a site visit at Beccles Yacht Station on the 6th January 2021. During the site visit questions and answers will be collated and included for a closed tender. We propose to send out a tender pack on the 11th January 2021 to those organisations that returned an "Expression of Interest return form". The tender pack will include a tender specification, a draft contract (NEC3 Short Contract) and a Q&A section. The tender return date is 24 January 2021. Our objective is to be ready to commence the work swiftly when the licence is approved mid to end February 2021. Completion date of the maintenance dredging is 15 April 2021.
