Project Summary

Acting as Principal contractor, 7Formation were responsible with creating a 72,000 litre Sea Mammal tank and associated operational and quarantine rooms within the heart of the trading National Sea Life Centre.

A 5m x 5m aperture was to be cut through the 370mm thick reinforced concrete slab, between the first and second floors. To enable the Sea Life Centre to remain trading. The works would require special planning with access for all materials via a hoist to an aperture through the external façade at third floor level. To prevent the overloading of the existing slab the tank base was to be suspended utilising steel beams bolted to the existing columns.

With the steels in place the insulation and shuttering could commence.
150 tonnes of specially designed concrete mix were pumped from the compound 100m in distance and 13m high to the working area within the heart of the building. With the base cast the reinforced walls were constructed 350mm thick to withstand the pressure from the 60,000 Litres of water required to fill the tank. 7Formation would be responsible for management of mechanical, electrical, life support systems, GRP lining, glazing, theming, graphics and special effects.
