CFA piling for a contig basement wall

2 Storey Restaurant Regeneration Project

As part of a refurbishment project the original, single storey, café was to be demolished to make way for a more aesthetically pleasing,  2 storey restaurant with a public roof terrace which would complement the prestigious surroundings in the Duke of York Square.  The design of the new restaurant has already won a New London Architecture Award for its state-of-the-art design.

After an intense tender process to identify the main contractor to deliver this new establishment, Westgreen Construction Ltd were chosen due to their expertise in delivering successful projects of this type.  Following their success Westgreen quickly contacted All Foundations (UK) Ltd to seek their advice on the piling aspect of the project.

After reviewing the information and visiting the site, All Foundations decided to utilise a CFA piling rig, a CM-50, to install the 92 No. 600mm diameter piles, which would make up the contiguous piled wall required for the basement.



LIPS is Ideal For 3 Storey Timber Framed Apartments

Project scope:

Demolition of two detached dwellings and replaced with two blocks of 3 storey timber framed apartments.

Due to the close proximity of a number of trees and subsequent roots, P W Roxburgh Building Contractors decided to approach All Foundations with a view to determine if our Level Innovative Piled slab (LIPS) solution would be more suitable than traditional foundation methods.

After discussing the project in-depth with our Head of LIPS, Mike Dorman, it became clear that LIPS would be the best option for the foundations from both an economic point of view and an environmental one. 


LIPS - Level Innovative Piled Slab Solution at Saffron Walden

Supported Living Accommodation - Saffron Walden, Essex

East Thames Housing Association identified a real need for the development of new ‘Supported Living Accommodation’ for parents of children and young adults with specific needs.  The site at Everitt Road in Saffron Walden in Essex was deemed to be the most suitable for such a development.

Due to the unique shape of the site, East Thames wished to develop an aesthetically pleasing building which would, itself, lend aid in creating a harmonious environment for all residents.  Therefore the building was designed in a fan shape rather than a traditional two storey terraced building. 

The front of the building was required to be a focal point and as such was designed in the shape of a rotunda.  The aesthetically pleasing design meant that many traditional forms of foundations actually became very expensive and difficult to utilise due to the curved shapes required.


Selwyn House Restricted Access Piling Case Study

Making the impossible, possible!

All Foundations were contracted to provide foundation piles to support a 7.5m deep sub-basement extension to the former Royal Sun Alliance Headquarters, Selwyn House, next to Green Park in London which is now a single residence. 

Due to the location of the building Ian Cull, our Senior Estimator for the Southern division of All Foundations, visited the site to determine the available access and concluded that Restricted Access piling would be required due to the very tight restrictions both on the site and in the surrounding area.

The challenge was to design and install piles to support compressive loads of between 300-700KN and tension loads of 325KN. The ground conditions being water bearing sand and gravel to a depth of 11.0m, overlying London Clay. The working area being 12m x 10m, set 3.0m below pavement level. The site being in a high security area adjacent to St James’ Palace and Clarence House, with a very narrow access road surrounding the building.
