SECURING EDGE BARRIERS

This article explains the problems inherent to edge barriers in many car park structures across the UK, and reviews the urgent need for their repair and strengthening, to prevent further incidents. A recent report, by the Institution of Civil Engineers and the Institution of Structural Engineers' Standing Committee on Structural Safety (SCOSS), recommended the careful checking of multi-storey car parks over 12 years old. The checks should include confirmation that their edge barriers are strong enough to withstand accidental damage by vehicles. Car parks built in the 1960s and 1970s were usually built with precast or in-situ concrete floors, supported by reinforced or prestressed concrete beams or structural steelwork. Such structures were often open to all weathers, and tended to deteriorate relatively quickly without adequate maintenance. Water penetration caused carbonation and spalling in the concrete and corrosion of the steel reinforcing bars. The damage to a multi-storey car park in Aylesbury was typical. HCL Contracts Ltd, in collaboration with the Engineers' Department of Aylesbury Vale District Council, devised a solution to repair the damage, so that the edge restraint was considerably better after repair than before vehicle impact had dislodged an external cladding panel and broke its interlocking concrete edges.
