Public liability and electrical pits

This paper presents the findings of the investigation into the state wide poor performance of recently installed electrical pits. At present, there are sixteen legal claims against the Department relating to electrical pits, where eight claims have been settled at a cost of almost $300,000 to the Department. Field observations identified the majority of failures concerning electrical pits involved poor installation practices and insufficient product strength. Concrete covers also contributed to the high maintenance costs incurred by Districts as a result of insufficient product strength for their intended location in relation to the roadway. As part of the investigation, trialling of alternative products was undertaken. Several trials in the Metropolitan District identified circular pits would produce vastly superior performance to that of rectangular pits. Circular pits have now been included in the most recent revision of MRS11.91 Conduits and Pits and almost 300 circular pits are currently being installed in two major projects in the Metropolitan District.
