Tulalip Water Pipeline Projects, Proposals 1 & 2

Project Summary

The Tulalip Water Pipeline Projects involved two contracts for the Tulalip Indian Tribe, valued at over $8.5 Million.  The projects provided installation of 36-inch diameter and 48-inch diameter steel water transmission pipeline in several segments connecting the City of Everett water distribution systems to The Tulalip Tribe's water system.  Construction sites were located within several jurisdictions including the City of Everett, Snohomish County and the Tulalip Indian Reservation.

The projects were incredibly complex and technical.  Portions of the project required shutdowns of major roadways around the Marysville I-5 corridor during summer months.  To mitigate any delays our teams worked day and night shifts during segments of the project that required shutdowns of major roadways in the area.  One segment of the contract included installation of shoring systems and pipeline along Highway 529.  Over 4,600 lineal feet of 48-inch steel welded pipe was installed and use of our APE Robovib was highly advantageous.   With the ability to drive sheets in low lying areas without use of a crane, IMCO was able to install the shoring systems throughout this restrictive jobsite area with minimal equipment and time added to the schedule.
