An archaeological watching brief was conducted by the Cambridge Archaeological Unit (CAU) on the 12th and 13th of July 2012, on land to the south of Addenbrooke's Hospital, Cambridge. The pipe trench and easement had already been dug and substantially backfilled by the contractor prior to the CAU being informed. As a result it was not possible to conduct a standard watching brief. A rather irregular trench c. 4.0m wide was re-machined, the location of this was determined to avoid the recently laid cable and to remain within the area of the easement. Severe groundwater issues, exacerbated by the contractor pumping groundwater from the trench into the archaeological area, meant that the majority of the features could not be excavated, however a number were revealed and planned, some relating to those found in earlier evaluation trenching.
