144 No 220mm diameter bottom driven steel cased mini piles were installed to depths in the region of 10Lm though pre-excavated holes through an existing factory yard to support pilecaps on top of which a steel portal frame extension to the factory will be constructed. Three rigs were used to ensure the works were completed within three weeks.
A swallow hole appeared beneath the patio area of a domestic bungalow, which undermined the existing foundations. The hole was grouted and then the foundations of the bungalow underpinned to prevent any future settlements.
Due to a tree preservation order, deep excavations were not permitted for the above development and therefore a piled reinforced concrete slab was constructed. This minimised the potential damage to the tree roots and kept the excavations into the ground within the allowed depths.
Due to the presence of drainage running underneath the proposed conservatory piled foundations were utilised to allow the foundations to be cast so that the foundation could ’span’ over the drainage without damaging it.
York Art Gallery underwent a major redevelopment and as part of the works a new mezzanine floor was installed. Piled foundations were installed to support the additional loadings from this new floor. As the works had to be carried out internally and access to the area of works was via a door opening small mini piling rigs were used to install bottom driven mini piles.
