Amendment A00002 dated 01/27/2026

24. RFP

Sheet C-1 Profile 6th Street Sewer line “A” shows note “reconnect service line as required by field verification”. It appears this service line is already connected to existing SAS to remain in place. If so, why reconnect? Please clarify.

COR

The note “RECONNECT EXISTING SERVICE LINE TO NEW MAIN” is currently connected to the existing sewer line; the existing sewer line is to be removed and replaced with New Line A, as indicated in Piping Schedule 1.

25. RFP

Sheet C-1 does not show elevation profile of existing SAS main on line “A” and line “B”. Since most of this work is existing line tie in work, won’t the existing SAS main be at same location and elevation as new SAS main? While SAS line “A” is on a new alignment this does not appear to be the case for Line “B”. Please confirm.

COR

The existing Line SAS is to be removed and replaced with Line A and Line B. The elevations should remain the same as before.

26. RFP

Is sewer service in all existing homes or bldg. tie ins to be completed in this work in current use and operation? If so, will continued operation be required when exist system must be removed and replaced? How long can service be down? Can adjustment to alignment be made with engineer approval to allow continued operation?

COR

Yes, all housing units are connected to the SAS Lines and are to remain in service. Service can be down when transfer of existing SAS line, that will be coordinated with the Facility Engineer and CEO for housing occupants’ notice. Yes, adjustment to alignments may be considered and approved by Facility Engineer and COR.

On Sheet C-1 Gen Note 5:

a. “.. separate trenches will be required in all cases (this shall be effective even though one line has been installed prior to the other)” Please clarify if this will apply and if so, how this is to be
