Kap Shui Mun Bridge, Hong Kong. Tower 4 Lower Strut Falsework.
Structural steel falsework designed for site fabrication and erection to support in situ construction of a 5 metre square prestressed concrete beam 30 metres long. The falsework supported the fresh concrete at a propping height of 15 metres.
City Point Building, London. Facade Access Scaffold & Landing Platforms.
During refurbishment of this 33 storey concrete framed office building we designed a large crane -handled scaffold structure to give access to the slab edges. The scaffold was designed to cantilever form the face of the building at any level. On the same project we designed a structural steel cantilever loading platform to enable materials to be simply transferred form the crane to the floor slabs. Our designs included comprehensive checks on the capacity of the permanent concrete structure to accept the loads applied by our temporary structures.
Canary Wharf, London. External Aluminium Common Platform Hoist Towers.
We have maintained a long working relationship with Universal Builders Supply of New York City, and their British subsidiary, to design and regularly inspect all their common platform hoist towers in the UK. UBS introduced this concept to the UK on the new Citybank building at Canary Wharf. It has subsequently been used on all the new high rise buildings at Canary Wharf and several other buildings in the City of London. The towers stand outside the building and support up to six Alimak rack and pinion hoists. On some projects some of the Alimak hoists are replaced by UBS’s own design of high speed rope-hauled materials hoists. All the hoists share a common opening through the building envelope, which can be as little as 4 metres wide, thus minimising the amount of curtain walling which has to be left off the building.
Swiss Re Building, London. External Aluminium Common Platform Hoist Tower.
An aluminium common platform hoist tower very similar to those used on the canary wharf buildings was designed for UBS and their client Skanska for use on the striking new Swiss Re building in the City of London. The tower supported two twin Alimak high speed passenger / material hoists and a unique heavy duty twin mast Alimak “Mammoth” passenger material hoist. Tower design was complicated by the geometry of the building and was closely coordinated with the permanent works designer.
Ma Wan Viaduct, Hong Kong. End Span Falsework.
1200 tonnes of structural steelwork was designed for site fabrication and erection to facilitate construction of a heavy prestressed concrete box girder 35 metres above ground level.
Ma Wan Viaduct, Hong Kong. Travelling Access Platform.
The Contractor required access to the outside faces of this 7.5m deep concrete box girder after removal of the falsework on which it had been constructed. We designed at traveling access platform in structural steel running rails on the top slab of the bridge
Canary Wharf, London. Special Heavy Duty Cantilever Loading Platforms.
To assist UBS in their problem solving role at Canary Wharf we have designed a wide range of special one-off temporary structures. The largest of these have been cantilever loading platforms to allow large loads to be safely transferred form the cranes to the building floors. These platforms were designed to be crane handled easily from one floor to another and on the plant room floors have been designed to support items of mechanical plant weighing up to 21 tonnes.
Nam Cheong Station Cofferdam, Hong Kong. Props and Walings.
Detailed design of propping scheme to support a sheet piled excavation 400 metres by 100 metres by 16 metres deep. The props reacted against the permanent structure which was constructed top down.
Touchwood Court, Solihull, UK. Props and Walings.
Detailed design of propping scheme to support a contiguous bored pile wall surrounding a basement excavation. The props reacted against the central section of the permanent ground bearing slab which was constructed in a first stage battered excavation. Temporary concrete thrust blocks were also employed in some locations.
