A452/A46 Thickthorn Junction Improvements - Topo Survey

Services required from supplier: To undertake a topographical survey to supplement an existing survey as well as a ground penetrating radar (GPR) survey for mapping underground utility apparatus. Both surveys form part of a suite of site investigation works commissioned in order to provide data to feed into the scheme design currently being undertaken.

The Thickthorn project requires additional topographical survey work to plug the missing gaps as well as plotting accurate GPR survey. It is preferred to use Greenhatch to acquire this information. This is because Greenhatch conducted the original survey and will therefore maintain complete liability for the accuracy of the survey provided. This also helps to ensure that the design work we have already conducted does not have to be extensively changed because it has been based on the original Greenhatch survey. The work completed historically was not procured by the County Council.
