Dear Mr. Gaherty:
AECOM

Waterloo, Iowa 50703

Attached is Change Order No. 1 for the Titus Lift Station and Force Main project submitted by WRH, Inc.
319-232-6531 tel
319-232-0271 fax
The following are the detail for the requested changes.
• Bid Items 8 and 12 — Change in valve manufacturers for the plug and gate valves. The lead time to receive the
valves from the specified manufacturers was over 1 year. See attached WRH Change Request No. 1
• Bid Item 44A — City Staff requested that a man gate be added to the perimeter fence to the life station perimeter
fence. See attached WRH Change Request No. 3
• Bid Item No. 46 - 60" MH needs to be added to the project for the connection of the force main to the existing
sanitary sewer. See attached WRH Change Request No. 2
• Bid Item No. 47 - Alignment change east of Parker Street to avoid the signal mast foundation. The design
alignment brought the force main into conflict with the mast footing and could compromise the structural integrity of
the mast footing. See attached WRH Change Request No. 4
• Bid Items 48A-G — Bedrock was encountered at Grandview Avenue. Directional drilling this area was not possible.
These items are to replace the pavement and adjust the sanitary manhole at Grandview Avenue. See attached
WRH Change Request Nos. 5 and 6.
AECOM recommends the City approves Change Order No. 1 for the addition of $58,822.15 and a revised total contract cost
of $6,242,909.15. The increase is 0.95% of the original contract.
Yours sincerely,
