Brendan Girt

Deacam Operations Mgr

Nothing short of exceptional Deacam P/L were engaged to perform various project works associated with the Bayswater Level Crossing Removal (LCRP). Quick turnaround from suppliers were paramount to achieving project deadlines. After approaching multiple transformer manufacturing companies, S.E.S ( Southern Electronic Services) were the only company who were able to guarantee the manufacturing lead time required. A 60 kva transformer ordered 25/11/16 and delivered 2/12/16 was nothing short of exceptional considering we were receiving indicative lead times from other manufacturers of up to 30 days. We will be happy to engage SES again.
