Hydra Capsule completes major jacking works at Bloomberg L.P.

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.

Hydra Capsule also provided contract service to fully install and carry out grout injection; to permanently transfuse each flat jack individually for the jacking force to be permanently induced for the duration of the project.

Tricky flat jacking operation completed successfully by Hydra Capsule’s purpose-built flat jacking and injection systems.

The works consisted of 21 off. Transfusion flat jacks rated at 40 tonnes.

Therefore all the jacks were interlinked and synchronously loaded to the specified defined loads, displacements/deflection and limits.

Once competed, each jack (which were jacked/lifted/preloaded with hydraulic fluid) was individually transfused using a double-release valve arrangement, to inject grout and release temporary fluid until the flat jack was fully transferred. Find detailed explanation of the above flat jacking operations at http://www.hydra-capsule.com/flat-jacks .

The key element of the operation, is the jack can be accurately monitoring and maintain the original preload and movement with the structural steelwork being subjected to additional loads and/or further stresses.

ST KATERINE DOCKLANDS, QUAYSIDE - JACKING & PROPPING WORKS

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.

Once these works were completed, Hydra Capsule also provided grout injection systems to permanently transfuse flat jacks and carried out concrete strengthening and repairs at badly damaged concrete areas.

Hydra Capsule - Hydraulic Jacking, Propping and Monitoring Division

Hydra Capsule have restructured its hydraulic jacking and monitoring division, with additional research, development and investment. Which has allowed our jacking systems, geodetic monitoring and real-time instrumentation to be completely integrated as one complete operating unit. This allow Hydra Capsule to offer a complete “one-stop” solution for all suitable applications, allowing for complete control and analytics of structures throughout projects.

Hydra Capsule is a leading subcontractor for supplying flat jacks, hydraulic jacking systems, temporary propping systems, electronic instrumentation, and real-time / long-distance monitoring. With over 30 years of experience within this market, Hydra Capsule has extensively designed and developed systems to suit all applications.

Currently Hydra Capsule monitoring division can offer:

Consultancy and Conceptual designs

Installation of instrumentation, monitoring equipment, temporary propping works, and hydraulic jacking systems

Real-time and long-distance monitoring, with the inclusion of provisional data analysis facilities

Complete data-logging and alarm / trigger limits integration; via SMS or email warnings, for complete monitoring control

Automated (solenoid control) and / or responsive solutions (manual control)

Integration of all electronic instrumentations (ie. Pressure transducers, movements displacement / LVDTs, stroke sensors, tilt sensors, strain-gauges and load cells) to one control software unit to analysis

Hydra Capsule have carried out numerous projects, previously Kingston Bridge – Glasgow and Guild Hall – London (which is still installed to-date), to current projects utilizing our system:

Birmingham New Street Station Redevelopment – Hydra Capsule have installed a jacking system with ULS to over 9,000 tonnes with load monitoring through pressure transducers, load cells and strain gauges. To relative displacement monitoring of structural movements, attached to the critical elements, to measure up to accuracy of +/- 0.01mm through Geotechnic monitoring devices. The complete system being data-logged and accessed through our wireless viewing page. The project is approx 18 to 24 months duration, prior to permanent installation works to be carried out.

Tate Modern, London Art Galley – Hydra Capsule were approached to design and install a hydraulic jacking system capable of 4,000 tonnes. The complete system, was designed and manufactured by Hydra Capsule to meet the Engineers specifications.

The hydraulic jacking system was required to be electronically controlled; single, multi-sets and/or all hydraulic jacks activated synchronously, achieved through the use of electronic non-return solenoid-control.

The monitoring element involved “real-time” monitoring during jacking phases and throughout the 12 months construction period. Monitoring the relative movement of the support beam to the structure. This was achieved by installed stroke sensors, deflection boxes, and Hydra Capsule’s relative laser levelling system. With the integration of pressure transducers to distribute loads through the correct load-path throughout the construction phases.

As stated above for each project, all the monitoring information is transferred from our on-site data-loggers to a wireless viewer website page and can be displayed and access 24/7 worldwide. In addition, Hydra Capsule software can introduce numerous specified tolerance limits, which then are exceed, will activate automated trigger alarm and distribute to all key personnel through an email or SMS text alarm indicating the location and description.

This will allow key personnel to review and analysis the information and trend data provided. To carry out the necessary works to the structural. Through change of the construction phase working or introducing of jacking adjustment, giving construction our full support.
