Project Description

This 400 year old Grade II Listed multi level property in rural Bedfordshire required underpinning using a piled raft scheme. Due to the property being listed and to ensure that as many of the original features of the property could be retained, the works were over seen not only by checking engineers and the local authority, but also the local conservation officer and heritage network officer.

The works were being undertaken as part of an insurance claim, Abbey Pynford worked closely with the main contractor who were on site undertaking superstructure repair works when sections of the underpinning were complete. The nature of the extremely old building meant that innovative propping details were required as old wattle and daub walls could not be temporally propped in the usual manner. Steel sections were bolted either side of the existing timber supports, props were then installed to the underside of the steel sections. This was just one of the many challenges faced by Abbey Pynford throughout the project that was completed ahead of time and to the satisfaction of all those involved.

Testimonial

“The grade 2 listed building is 400 years old and was in poor condition. After several alterations had been added to the property, we had to use a multi level piled raft underpinning scheme. The property required visits from the local conservation and heritage officer to ensure, as much as possible, that the original features were not removed.”

Section 1 complete Due to the size of the property some 280m2 in area, the underpinning had to be undertaken in 4 section to ensure that the property remained stable. The photo show the 1st section complete ready for the second section propping work to start before the two sections of slab can be cast together.
