Geotechnical engineering services

Description

Notification of award the following: Using Achilles UVDB product codes 4.6.27 Geotechnical Site Investigation Services and 4.99.5 testing and analysis services (Utilities) to derive the list of companies, we are tendering our CP0008 (H006.A.CP.CX.2) Geotech ground investigation and factual reports project. We are conducting this procurement process because we want to appoint the most suitable supplier(s) for provision of Geotech ground investigation and factual reports. This pre-qualification stage is to enable contractors on Achilles Vendor Database (UVDB) to answer questions regarding their previous experience, in order to shortlist a maximum of 10 contractors that would be invited to tender. You will be asked to provide the geotechnical ground investigation and factual report services for the promotion of major project schemes where initial work is associated with Beckton STW [B], Mogden STW [M] and Guildford STW [G] and on ongoing AMP7 capital programme. This is the first document (the second will be issued as ITN), which we will use to select and establish a framework of 5 preferred contractors for a period of up to 7 years (as initial 3 years and renewed annually in April thereafter to 31.3.2025). The initial schemes can be summarised as follows: WWNI Beckton STW AMP7 Improvements. The required changes to provide consent compliance resilience cannot be achieved by wholly utilizing the existing effluent stream and sludge stream treatment assets; and will require upgrading of the preliminary, primary and secondary treatment works and provision of a new control room. The treated effluent discharge point is to remain in its current location with flows discharged directly into the River Thames. The London Borough planning authority is Newham Borough Council. WWNI Mogden STW AMP7 Improvements. The required changes to provide consent compliance resilience cannot be achieved by wholly utilizing the existing effluent stream and sludge stream treatment assets and will require upgrading and/or replacement of the preliminary, primary and secondary treatment works. The treated effluent discharge point is to remain in its current location with flows discharged directly into the River Thames. The London Borough planning authority is Hounslow Borough Council. This scheme may also comprise works at Iver South Sludge De-watering Centre and permissions being granted through Slough Borough Council. Guildford STW Relocation. The project is part of the Slyfield Area Regeneration Project (SARP), a major regeneration scheme in the Guildford area. SARP involves the relocation of the existing Guildford STW to the old Slyfield Landfill site. A 1 500 mm diameter gravity tunnel close to the eastern SARP boundary shall transfer flows to the new STW location. Full planning permission will be required from Surrey County Council. Close liaison with the SARP development team will be required throughout the preparation of the planning application and Environmental statement to ensure a consistent approach is taken to the assessment work and cumulative impacts are carefully addressed. To obtain the planning permission, and also to carry out the design, geotechnical ground investigation and factual report are required.
