Touchmark Water Main Extension
Boise, ID

Erickson Civil staff worked with the City of Meridian to prepare a full civil engineering design and construction bid document set for the Touchmark Crossing Water Main Extension.  The project included 4400 lf of 16” water main to provide a connection to a low pressure zone between St. Luke’s Hospital and the intersection of Overland Road and Eagle Road.  The project included several unique challenges including working within ITD ROW and Nampa Meridian Irrigation District ditch crossings.  The water main extension crosses beneath both lanes of Interstate 84.  A 30-inch diameter steel casing was installed utilizing boring and jacking methods starting from the St. Luke’s side of the interstate.  Concurrently, 16-inch main was installed via conventional trenching methods from the casing design end points to the connections at St. Luke’s and at Overland and Eagle Roads.  Our staff represented the City of Meridian throughout the duration of the design and construction of the project including license agreement acquisitions with NMID and Utility Permitting with ITD.  Easement acquisition was also required from neighboring property owners in order to make the necessary water system connections through private property.  The project was successfully completed ahead of schedule and within budget.
