Knowledge Check
Defects, collateral warranty liability and proof at an undefended trial

This Knowledge Check examines One Hyde Park Limited's claim against Laing O'Rourke Construction South Limited for serious defects at the One Hyde Park development. Shortly before trial, the defendant said that it could no longer fund its defence, entered a creditors' voluntary liquidation process and did not participate in the hearing.

The court struck out the defence but required One Hyde Park to prove its case. The judgment considers the status of factual and expert material where the witnesses are not called, One Hyde Park's repair responsibilities under the lease structure, and liability under a 2010 collateral warranty tied to the 2007 main contract.

The defects concerned chilled-water pipework, butterfly valves, soldered joints and a pantograph cradle. The court accepted the claimant's evidence on breach, causation, remedial scope and quantum, including the need to replace almost all chilled-water pipework during a programme expected to last about 10.46 years.
