A New Year’s Resolution: More Consideration of Time Limits

In a world of pure cooperation, if the owner of a construction project or a contractor causes a problem, the responsible party would admit fault and make amends—rendering the negotiation of a construction contract unnecessary. In our less than ideal world, owners and contractors have adverse interests, the party at fault is not always clear…
Washington Supreme Court Ruling Could Bring Changes to the Construction Industry
Originally published by the Seattle Daily Journal of Commerce on November 3, 2022.
In a 5-4 decision, the Washington Supreme Court recently ruled in Tadych v. Noble Ridge Construction, Inc. that a contract provision providing a one-year limitation period for filing a construction defect lawsuit was “unconscionable” and therefore unenforceable.

Benefits and Risks of Involving a Project’s Contractor in The Design

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 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…
An Owner’s Guide to Accessibility Claims in Washington
When owners engage architects and accessibility consultants to design their projects, they naturally expect good design, but they must also be sure the design provides all users with the practical ability to use and enjoy the end result. Civil rights acts such as the ADA and Fair Housing Act were enacted to provide certain protected…
Stoel Rives Helps WSDOT Defeat a $640 Million Claim
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…

Update on Alaska Way Viaduct Replacement
Occasional visitors to Seattle may be surprised to discover that their favorite route from the airport to downtown has changed. State Highway 99 no longer links to the Alaskan Way Viaduct into downtown Seattle. The waterfront viaduct has been closed and demolition has begun. The Battery Street tunnel that connected viaduct traffic to Aurora Avenue…
