A435 Racecourse Geotechnical Remediation

Description

The project site is situated along the A435 Evesham Road, between the Racecourse roundabout and the GWSR Bridge (approximately postcode GL50 4SH). The plan includes the installation of approximately 200 meters of piling in the embankment of the northbound carriageway, located just south of the GWSR Bridge. Summary of Construction Phase key deliverables are as follows: The embankment in this location has been subject to geotechnical monitoring over recent years, due to the appearance of longitudinal cracking within the northbound carriageway surface. The visible cracking is the result of poor embankment material which has slowly subsided overtime. This scheme will install two rows of sheet piles, with approximately 170m being installed at the toe of the slope, and 130m being installed at the crest to stabile the embankment. In addition to geotechnical remediation measures, the northbound carriageway will be subject kerb line realignment and full depth reconstruction, covering areas showing the most significant cracking and subsidence. The footway within these extents will be reconstructed including some drainage works. Gloucestershire County Council are seeking a Principal Contractor to deliver the construction phase of this scheme.
