Geotechnical Engineer Services

Tender description

The City of London Corporation proposes to relocate three wholesale markets to co-locate the existing operations at Smithfield (meat and poultry), New Spitalfields(fruit and vegetables) and Billingsgate (fish) markets, collectively referred to as the City Markets, to a single site. The proposed location of the consolidated market is the site of the former Barking Reach Power Station (the Site) at Dagenham Dock, in the London Borough of Barking & Dagenham (LBBD). The Geotechnical engineer is to be appointed for the duration of the development,including the potential to provide services to the main contractor under a novation agreement. In February – July 2021 alternative foundation options, including the extent of re use of the existing Barking Reach Power station substructure were investigated.Following soft market testing with general contractors the report concluded where there were existing foundations these could be taken as ‘existing ground conditions’to support a ground bearing slab for the new wholesale market buildings and new piles would be inserted for the proposed frame. Lot 1: The objectives of this appointment include: • To develop previous engineering strategies and develop geotechnical designs,particularly surcharging and to coordinate with the developing conceptual and superstructure design. • To design and specify a testing, monitoring and surcharging phase for ground improvement (18 months) taking into consideration the materials management and the need for amending the current Environmental Impact Assessment. • Attend design workshops on building, car parking and yard engineering performances and tolerances and lead below ground geotechnical design to derive optimum balance of safety, programme, cost, risk and sustainable design minimizing embodied carbon • Assist review of imported soils and monitor testing results. • Following testing provide a spatially coordinated foundation design to Eurocode 7 • Minimise settlement risk • To provide design warranty to the geo technical design such that it can be relied upon by the main contractor and incorporated into the building warranty • Support the design team in the monitoring of new and existing infrastructure on, under or adjacent to the site • Support the development of designs for permanent earthworks including pavement subgrade assessment for pavement design • Support trials (if required) for surcharging phase for ground improvement
