Waterman provided structural, civil engineering services from the planning stage to the completion of the project.
The new foundations have been designed to work within the load bearing and vibration restrictions set by Crossrail which are required for the further Crossrail 2 tunnels which run underneath the St James’s Market site.
In the planning of the location of the link tunnel between the two buildings, carefully planning and extensive surveys were carried out in order to avoid the existing main sewer under the carriageway and also matching the basement levels of the two buildings.
In order to optimise of the steel tonnage, we worked with the steel sub-contractor, to optimise the weight of the fabricated beam sections while achieving the dynamic response requirements of the floor slabs.
Waterman worked closely with the engineer from D&B Contractor, to develop a steel-concrete connection detail which avoided the forming of pockets in the shear walls and also fulfilling the weight limit for lifting cast-in items onto the slipform rigs.
Sharing structural 3D Revit model with sub-contractors helped in the design co-ordinations between services and structures as well as between the cast-in items and the reinforcement layout.
The structural analysis model for the base build was shared with the staircase subcontractor to enable them to design the cantilevered featured staircase and taking into account the base build frame in assessing the dynamic response of the staircase.
