A stage of concreting the foundation plate of the tower-type building has began on the Warsaw Spire's building site. It is one of the most important stages, giving foundations for 220-metre high tower. The bottom slab of the space of 2 300 m2, on which the 49-storeyed building will be based, is placed 16 metres above the soil.
During the first stage, which lasted two days, about 1 800 m2 of concrete with fine aggregate was used, which equals 200 concrete mixers. Next stages of concreting will last for four weeks, taking into consideration the required service interruptions. Concreting under the building A will altogether take 6 000 cubic metres of concrete, which is to reach over 2,5-metre gauge.
The Warsaw Spire complex is being erected in the block of Grzybowska, Łucka, Towarowa and Wronia streets, and is to offer the space of 100 000 m2 . It is exactly such a space that allowed the investment to win the first place in Book of Lists business ranking as the biggest office project currently realised in Poland. In the office sector, the building is also the biggest one being currently erected in Europe. The already mentioned ranking was prepared for the 18th time by Warsaw Business Journal.
The investment is composed of three buildings, one 220-metre high scyscraper and two adjecent to it 55-metre high buildings. Between the buildings there is to be created a public space available for the residents – a spacious, leafy square, full of street furniture and fountains.
Ghelamco Poland is the developer and general contractor of Warsaw Spire. All the realisation stages proceed in accordance with the requirements of environmental certification BREEAM.
