Design Construction Impacts


Existing utilities continues to be a concern for potential schedule delay and increased construction cost.  We are working with the Utility Companies and the Contractor to minimize impacts.

 

More than anticipated ground water and offsite water has impeded the Contractor's ability to do contract work.  Dewatering system and French trench were installed to help mitigate the problem.  However, we anticipate that this problem will be ongoing and will have cost and schedule impacts to the project.

 

There is a potential risk of schedule and cost impacts for Wall 1 and SR522 off-ramp widening work due to limited work space, nearby sensitive areas, offsite and ground water and working through the wet winter.  We are working with the Contractor to minimize the potential cost and schedule impacts.

 

Environmental Impacts / Compliance


There were several water quality exceedances on this project.  We are working with the Contractor to eliminate/reduce these exceedances.  There were no environmental violations thus far.

Due to potential environmental risk for Wall 1 and SR522 Off-Ramp work during the wet winter months, WSDOT have suspended this work until Spring 2007.

Impacts to Traffic

Traffic has experienced narrower lanes and shoulders, slower speeds and occasional stopped traffic in construction work zones during the daytime.  Some night and weekend lane and roadway closures occurred during construction period.  A comprehensive public information effort to share timing of construction activities and traffic impacts has occurred.
