The court’s ruling revives a

The roles of designers and contractors are being combined for more and more construction projects, an approach that comes with both benefits and risks. Several methods of project delivery are commonly in use, none of which is entirely exclusive — different projects may include different and overlapping roles for owner, designer and contractor. In my

In late 2019, the Washington State Department of Transportation and Seattle Tunnel Partners (STP) engaged in a nine-week trial of claims arising from construction of the new State Route 99 tunnel under downtown Seattle. One major issue for the jury was whether STP had encountered “differing site conditions” – unknown underground conditions that differ materially

The biggest construction project in Seattle in recent years has been the replacement of a seismically compromised waterfront viaduct with a tunnel carrying State Route 99 under downtown. The project was delayed for about two years while the contractor repaired damage to its tunnel boring machine. The contractor claimed that the damage was caused by
