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.
Piled, reinforced concrete ground beams installed on a site to support a small development of domestic dwellings. Piling was required due to poor ground conditions with insufficient bearing capacity.
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.
A challenging site which clients wanted to construct a property on a steep slope. Driven piles were installed using a small rig, which could access the restricted areas. Reinforced concrete ground beams were constructed however ‘steps’ in the beams were required to follow the slope of the ground.
Access to the rear of the property was only available through the existing house. Small hand carried Grundomat piling equipment was brought through the property into the rear garden allowing the foundations and extension to be constructed.
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.
Bottom driven mini piles were installed through pre augered holes to ensure a sufficient depth of pile was achieved on site through potentially obstructed ground.
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.
A new school building was constructed alongside the existing school. Due to poor ground conditions traditional strip foundations would have been uneconomical and therefore bottom driven piles were installed with reinforced concrete ground beams to support the new construction.
The existing signal box had started to settle as a consequence of its age and that it was sitting on 15 metres of very soft ground. Due to the very restricted access around the structure, limited headroom restriction and that the works were close to ‘live’ tracks our small mini piling rig was utilised to install bottom driven mini piles.
