Please join us for an informational meeting to discuss an upcoming large diameter tunneling project, the W-6 Upper Segment: Hwy 90 to SW Military Drive Sewer Main Project.  This project will be procured through Request for Competitive Sealed Proposal (RFCSP) and is scheduled to be advertised in the Spring of 2020, and awarded in June of 2020. 

               

The work under this solicitation will include the replacement of an existing 54-inch gravity sanitary sewer that currently runs through the Joint Base San Antonio - Lackland Air Force Base with approximately 5 miles of 104-inch gravity sewer pipe from a point near the intersection of SW Military Drive and Old Pearsall Road, extending northwest along SW Military Drive to the intersection of SW Military Drive and US Hwy 90, where it turns east along US Hwy 90 to a point near the intersection of US Hwy 90 and South Callaghan Road.  The scope includes about 26,400 LF of 144-inch tunnel at depths ranging from 30 ft up to 140 feet in the Navarro Clay Formation.   The tunnel will be lined with 104-inch diameter Fiberglass Resin Pipe.  The project will also include the installation of approximately 2,600 LF of 60-inch gravity sewer pipeline via tunneling and open cut, including a crossing under Leon Creek. The scope includes the tie-in to the SAWS W-1 Lower Segment Project, which will be accomplished by installing approximately 400 LF of 78-inch gravity sewer pipeline via open cut. The 60% design phase will be complete in September, and a summary of design and geotechnical data will be presented at this event.

 

Registration will begin at 9:00 am, with the formal presentation starting at 9:30 am. The presentation will provide important information about the project, and will include instructions to attendees who wish to participate in a self-guided site visit.  Attendees should RSVP by Friday, October 11 for this event.
