Formwork Finishes on Top at ManchesterFormwork Finishes on Top at Manchester

Hunnebeck TOPEC modular slab formwork system, supplied by SGB UK, has enabled north west based concrete frame specialist ,SGG Construction Ltd, to meet a demanding fast-track programme for the construction of a major new office development at Stephenson Square in Manchester. The system, used on site at The Hive in the city centre successfully achieved the concrete quality finish specified by HKR Architects, where large areas of soffits were left exposed on the completed building.

The £11.5 million, 10,200 m² sustainable office building is designed to meet the needs of a commercial market that demands low environmental impact and optimum flexibility of tenancy. With a project completion date of January 2010, main contractor, Bardsley Construction, set testing deadlines for all their package subcontractors and SGG Construction were required to complete the primary concrete frame in a build period of less than nine months.

Due to the logistical constraints of the city centre site, SGG Construction had to source a suitable alternative to traditional formwork methods. SGB was approached and they proposed the Hunnebeck TOPEC slab panel system which comprises just two basic components. The system is designed to achieve high output rates in conventional building applications.

For ceiling heights of up to 3.5m, the system is easily erected from below, thereby reducing the requirement to work at heights. At The Hive, HKR Architects designed ceiling heights to less than 3.4m in order to reduce building volume and facilitate a more efficient heating and ventilation system.

On the ground floor, which is to be utilised for retail space, the ceiling height exceeded this and reached an increment of 4.5 m. Here the TOPEC LIFT remote-control scissor lift ensured quick, efficient and safe installation of the slab formwork.

Over 50,000m² of straight, curved and tapered convex curved Kalzip aluminium standing seam sheets have been installed on Dublin Airport’s impressive new Terminal 2, Pier E and associated buildings. Arup and lead architects Pascall+Watson specified a full acoustic Kalzip system for T2 which was installed by Portuguese building envelope project manager and contractor, Martifer.

The T2 building has two main sections which sit astride the existing access road to Terminal 1 - a Check-in area and a Departures / Arrivals area that are connected via a link bridge.

A rainscreen system has been installed on the Kalzip sheets covering this Check-in area and the tightly curved parts of the Arrival / Departures area. Kalzip developed a special seam clip enabling Martifer to achieve a suitably robust connection between the Kalzip weather sheets and their rainscreen support system.

A central spine continues from the main 3-storey curvilinear T2 building through to the 400 metre long Pier E that will provide boarding gates and parking for up to 19 aircraft. PJ Hegarty & Sons are the main contractor and Lynch Roofing Systems Ltd the Teamkal contractor for Pier E.
