The project scope included constructing a new 42-inch storm line from the intersection of 30th Street NE and ‘I’ Street NE to the existing Brannan Park Pump Station. The new storm pipe replaced the existing 30-inch storm pipe to relieve street flooding that results from the limited capacity of the existing 30-inch line to convey the storm water to its current Brannan Park Pump Station discharge point. This project is a continuation of the 30th Street NE Area Flooding Phase 1A project, where a new 42-inch storm line was installed along 30th Street NE from ‘C’ Street NE to ‘I’ Street NE in Summer of 2015. The project also included a joint utility trench within a private alleyway for PSE and Comcast work.
Change Order No. 3 allocates additional funds to the Contract to address contractor invoices related to erosion control measures, unsuitable soils excavation and changes to the foundation material in the utility trenches, and additional restoration of private properties within the existing storm easement area.
A project budget contingency of $5,082.20 remains in the 462 Storm Fund. |
