Hi Hassan,
Here are our review comments before we proceed with the final order.
1) Please include a note for tracer wire and marking tape. Below is the 2008 ODOT spec, which I see we call out in the specials in Section 1.02 under Quality Assurance. I would like a note added to ensure “Marking Tape and Wire shall be included in accordance with 2008 ODOT specification 01140.45”. This is in the original spec’s and will be installed on all non-metallic piping.
01140.45 Marking Tape and Wire:
(a) Installation - Install marking tape and wire over all nonmetallic water lines, including service
connections. Place a continuous solid copper wire along the top of all water pipe, including service
lines. Secure to the top of the pipe at maximum 10 foot intervals using 6 inch strips of 2 inch wide
duct tape. Tie all splices and make them electrically continuous and waterproof. Provide access to
terminal ends of the wire at all valve boxes, meter boxes, fire hydrants, and vaults. The result of this
installation shall be a continuous wire circuit electrically isolated from ground. Place the marking
tape approximately one foot above the top of the pipe for its full length.
(b) Accessibility - Make ends of wire accessible in water meter boxes, valve boxes or casings, or
outside the foundation of buildings where the pipe enters the building. Provide wire access at
locations no more than 1,000 feet apart.
(c) Testing - Test for continuity and isolation from ground in the wire after all work has been
completed on the test section. Perform intermediate testing after backfilling operations and prior to
surface restoration work. Test continuity between access locations by use of a temporary wire
connecting test points in-line with an ohmmeter. Measure resistance with an approved ohmmeter
that has been properly calibrated. The continuity of a test section will be accepted if the resistance of
the test section does not exceed 5 ohms for each 500 feet of location wire being tested. Measure
isolation from ground with an approved 1000 volt Megger, applied for one minute. The isolation of a
test section will be accepted if the isolation resistance of the test section is at least 10 megohms.
Locate and repair all breaks or defects in the wire and re-test until specified results are obtained.
2) We want to ensure all the AC main pipe removed up to the 20” cross main on 5th. It was hard to determine if it is all being removed from the plan sheet. Also I did not see a bid item for removal and disposal of AC pipe for the sections that will not be abandoned. Is this incidental to the work? It is in the original contract section 02700G and the cost is incidental as per section 01000-1.08 –O.
3) Included my review estimate and plan sheet comments in the above attachments. There are a few items called out on the plan sheets that do not match the estimate. I have underlined these items. I also high-lighted the items that I could account for on both. I double checked these numbers and they match the bid quote. They are paid based on unit price as constructed, no lump sum items.
4) The cost for manhole in question is the manhole on Stowers.
Thank You,
Jennifer Cline, P.E.

Hi Curtis,
Please see below the response from Jennifer and can you tell us what is the time delay on waterline material delivery?

Hi Hassan,
Please confirm the delay of expected delivery of the water line materials.
I would like to proceed with the replacement of the Stowers Rd. waterline. We most likely will need to give the contractor a delay for procurement of materials on the Stowers Rd. portion of work only.
