CC Ground Investigations Limited (CCGI) was contracted by Balfour Beatty (UKCS) Living Places (BBLP) to undertake a ground investigation under the technical direction of the Engineer; WSP, to assist with the design of a new 8km Bypass to the West of Hereford City Centre. The proposed route runs through agricultural land and across the River Wye.
Seventy cable percussive and rotary cored boreholes to depths of up to 35m, over 160 trial pits and in-situ testing including California Bearing Ratio and BRE 365 Infiltration Testing.
Fieldwork activities were carefully programmed with BBLP to minimise disruption to landowners. A solution to assist with access, minimise disruption and protect growing crops was agreed upon and designed with BBLP in the form of a trackway. The trackway was utilised in several sensitive areas across the scheme and was carefully coordinated and planned to minimise risk and provide a practical and cost-effective solution in conjunction with ecological considerations.
The works were carried out using in-house drilling rigs and approved contractors. All works were supervised on a full-time basis by suitably qualified CCGI Engineering Geologists, with logging carried out to BS5930:2015. Engineer’s logs and data were issued to the Engineer during the fieldwork period, to allow laboratory testing to be scheduled. Laboratory testing was undertaken at UKAS accredited facilities.
The results of the investigation were presented as a factual report in PDF and AGS data formats.
