Textomur Reinforced Soil with PrIDE

Product: 
Textomur
Client: 
Tyne & Wear NHS Trust
Contractor: 
Laing O'Rourke
Project: 
PrIDE Ryhope

The Project

As part of a £68 million investment plan, Tyne & Wear NHS Foundation Trust proposed the re-development of part of the former Ryhope General Hospital site in Sunderland. The proposed scheme includes a new 122 bed hospital and would be built by Laing O’Rourke under their NHS Procure 21 Partnership with the Trust. Extensive enabling works were required on site to facilitate the construction of the new buildings, with a completion date of Summer 2014 the aim.

 

Solution

Following the demolition of the old buildings on the site of the former Ryhope Hospital, Phi Group were contracted to design, supply and construct two terraced reinforced earth slopes to provide plateaux to allow the construction of Wards 2 and 3 of the new hospital. The majority of the terraces could be formed using unreinforced slopes, however, at two pinch points at the corners of wards 2 and 3 the slopes had to be steepened to 65 degrees due to the close proximity of other building and services. The landscape architect required that the slopes were to have a vegetated finish, therefore Phi Group’s Textomur  green face reinforced soil  system offered the perfect solution.

 

Construction

To minimise both the economic and environmental effects of importing quarried granular fill, the as dug clay from the site was lime stabilised and used in the construction of the reinforced earth slopes.  In addition to this, the slopes were designed with a surcharge load of 40kPa to accommodate the raft foundations for the new wards. Phi Group constructed 550m2 of Textomur reinforced Earth slopes in a 5 week period.

 

Benefits

Phi Group were consulted from the early design stages of the project which meant we were able to use our experience and design expertise to offer the Client the most cost effective and buildable solution from our wide range of products. Environmental and aesthetic issues were also taken into consideration.  Phi Group provided Laing O’Rourke with the complete package, providing a full design, supply and installation service.
