Hydra Capsule commissioned to design, supply and preloading of temporary propping struts

The project is one of the largest private investment within the United Kingdom / Europe for an commercial development for Bloomberg London, the construction project for the new European Headquarters for  Bloomberg L.P.

The development comprises two high-grade specification office buildings in the City of London. I  t will include some retail units at ground floor level, and a new entrance to the London Underground, Bank Station.

Hydra Capsule flat jacks ranging from 50 to 350 tonnes were provided. (Models FJ25, FJ-48 and FJ-60).

Summary

"Hydra Capsule provided over 5,000 tonnes of  preload jacking forces throughout the project; with props extending over 25 metres in length".

Hydra Capsule manufactured over 40 number permanent flat jacks to pre-loaded and pre-stress numerous locations of the perimeter steelworks’ prop struts and waling arrangement. To assist with structural strengthening and l limiting displacement and ground settlement and displacement within the critical locations (ie. surrounding offices, buildings and listed church), whilst the full excavation works were completed.

In total the temporary support system was install to a depth of - 24 metres and while all the ground works were completed prior to the concrete core structures being erected.

All works were carried out using high-accurate movement LVDTs (+/- 0.02mm) and load sensors (+/- 1 kN) to meet the critical loading and displacement criteria provided by the structural consultant engineers.

The complete system was connected to Hydra- Capsule ‘purpose built’ read-out structural monitoring equipment / control unit. Which allows all information to be provided in "live" real-time data display.

The St Katharine Docks, in the London Borough of Tower Hamlets, were one of the commercial docks serving London, on the north side of the river Thames just east (downstream) of the Tower of London and Tower Bridge. They were part of the Port of London, in the area now known as the Docklands, and are now a popular housing and leisure complex.

Multi products and services provided and completed by Hydra Capsule at the Quayside Redevelopment Project.

The works involved a mixture of products and services to support the complex remedial works throughout the site.

Hydra Capsule used permanent flat jacks to pre-loaded and pre-stressed numerous areas of steelworks, to assist with structural strengthening and limiting displacement and deflection of critical areas within the structure.

In addition, Hydra Capsule also supplied temporary propping support systems at critical and high-risk areas of the project. Installing supports up to 400 tonnes (Mega-Prop) at particular location(s). With the inclusion of long-stroke (+150mm) hydraulic jacks to synchronously pre-load the supports.

All works were carried out using high-accurate movement LVDTs (+/- 0.02mm) and load sensors (+/- 1 kN) to meet the critical loading and displacement criteria provided by the structural consultant engineers. The complete system was connected to Hydra-Capsule ‘purpose built’ read-out monitoring control unit. Which allows all information to be provided in “live” real-time data display.

Major Project completed by Hydra Capsule Limited at Reading Station Development.

Hydra Capsule recently completed temporary propping throughout the Reading Station, ranging from supporting a complete footbridge, while under demolition works, to retaining over-loaded ground conditions. With additional hydraulic jacking designs to hydraulic lift and support over tolerance movements on the station's structural steelworks.
