Renovation of the Amsterdam Concert Hall
Alexander J. Verstraeten; Fundex Piling, The Netherlands
Work started on the building of the Amsterdam Concert Hall in 1880 by driving over 2000 wooden piles of 13 m on which foundation beams out of wood and brickwork were made. During construction the design was changed. This was due to the latest German developments, requiring double walls instead of single, so that the space in between could be used for ventilation and heating. Therefore, the pile load, originally designed at approximately 100 kN, increased even to 170 kN for some piles, causing settlements and unacceptable cracks in the brickwork. Settlements of up to 18 cm were measured. In 1985-86 around 400 vibration-free Tubex-displacement piles were installed under the Concert Hall, with a shaft of O355 mm, a pile shoe of O560 mm and a pile length of approximately 18 m. After these Tubex piles had been installed, they took over the complete weight of the whole building, thus eliminating further settlements and damage. 95% of all construction activities took place while the concerts went on. The chosen solution also made it possible to create a new basement under the Concert Hall as an extension for dressing rooms, etc.
