2017 Edition City of Seattle Standard Specifications for Road, Bridge, and Municipal Construction

PREFACE

The 2017 Edition City of Seattle Standard Specifications for Road, Bridge, and Municipal Construction (“2017 Standard Specifications”) have been prepared by Seattle Public Utilities in cooperation with the Department of Finance and Administrative Services, Seattle Department of Transportation, Seattle Parks and Recreation, Seattle City Light, and the Seattle Center. These Specifications have been coordinated with the 2017 Edition City of Seattle Standard Plans for Municipal Construction.

The 2017 Standard Specifications apply whenever any public or private construction is performed within the Rights-of-Way of the City of Seattle including work performed by private parties at their own expense under authority granted by ordinance of the City Council or by permit from the Seattle Department of Transportation’s Street Use section.

VERTICAL BAR: For the convenience of our users, we have indicated current text that has been revised from the 2014 Edition Standard Specifications with an adjacent vertical bar along the outside page margin (as shown here). Additionally, the table of contents shows all sections that have been revised in BOLD TEXT.

Our sincere thanks and appreciation to all who participated in the effort of producing this 2017 Edition of our Standard Specifications, and to the many other City personnel who provided review and submitted comments.
