Technical Director
West King Street Renewal
Overview
Our team provided geotechnical design services to support the complex regeneration of West King Street, Hammersmith. The project included the addition of two storeys to the Grade II listed Town Hall building and demolition of the 1960s Town Hall extension. The plan also outlined the construction of four new blocks, each up to seven storeys high with a part-single and part-double storey basement.
Key details
Project name:
West King Street Renewal
Client:
London Borough of Hammersmith & Fulham & A2 Dominion Developments Ltd
Location:
Hammersmith, London
Services provided:
- Ground movement and party wall building impact assessment
- Soil structure interaction and analysis using Plaxis 3D
- Thames Water sewer impact assessment
- Retaining wall analysis
- Outline temporary works basement construction sequencing
Challenge
Our clients faced a number of challenges, including several party wall buildings, Thames Water sewers and a former creek culverted beneath the original Town Hall. Our geotechnical team worked closely with the Structural Engineer and Main Contractor to undertake both 2D and 3D ground movement modelling to assess the impact of construction on the existing buildings and sewers.
Solution
Our modelling allowed ‘high risk’ zones to be identified and targeted for structural strengthening to protect existing buildings prior to starting works on site. Through the use of advanced soil structure interaction analysis, we were able to show that the impact of scheme was within acceptable limits to Thames Water.
RPS’ experience, pragmatism and holistic approach provided an optimal basement construction sequence which limited impact on party wall buildings while optimising the basement excavation programme.
