It might not ever be an issue, but I think we need to wait until I sign and date it. It may have a May 21 City

All,
The pre -audit for Supplemental Agreement #7 for services to split US 63 Segment #3 into two plan sets is
complete. See comments below.
No changes are necessary to the revised SA#7 forwarded on 5/9/12 and also attached to this email. With that
revision, the total estimated fees were increased from $145,900 to $150,600. The increase added 8 staff hours
for possible railroad coordination and 20 staff hours to prepare for and attend a single public information
meeting.
The Department will be reimbursing the City of Waterloo for 100% of the cost of SA#7. Federal aid is not
involved and FHWA authorization is not necessary to proceed.
The purpose of this supplemental agreement is prepare "alternate" plan sets if the entire project may not
proceed to letting for construction in 2013. The target letting for the alternate plans is December 18, 2012. Per
IM 3.005, preliminary and check plan milestones for a major project in the December letting are in June and
August. Obviously, AECOM must be given maximum opportunity to complete the work and submit for this
target letting.
The City of Waterloo and AECOM are requested to approve and sign SA#7 as quickly as possible. A copy of the
signed agreement should be emailed or faxed to the District Office for full execution. The originals may follow
by mail.

It is understood an addendum to the City -State project agreement is required to formalize the responsibilities
created with this SA#7. That addendum has been drafted and is being reviewed internally at this time. It
includes provisions to make the Department responsible for the cost of SA#7 and for the "temporary" or "short
term" project improvements that will be necessary if the alternate plans proceed to construction. The
addendum may not be available before the City of Waterloo could approve SA#7. The City is requested to not
delay acting on SA#7.
Please call or reply if you have any questions. Thank you for your assistance with this matter.

Bob,
As requested in your e-mail of May 2, 2012, we have looked at the draft agreement and the proposed estimate of
AECOM and its subconsultants. We are providing this memo in lieu of issuing a pre -audit report. The scope of
our review is as follows:
Draft Agreement:
The agreement appears acceptable as proposed.
AECOM:
Labor rates are reasonable for contract negotiation. Overhead rate reflects the most recent proposed rate,
acceptable for contract negotiations. The fixed fee is proposed at 13% of direct labor and overhead costs which is
acceptable for contract negotiation. Contingency was proposed at 10% of direct labor, overhead and direct
expenses.
Craig Ritland Landscape Architects and Robinson Engineering:
Subconsultants are minor in nature and effectively will be reimbursed as specified. Rates proposed are loaded
rates; resemble previously proposed rates, and are reasonable for contract negotiation. No contingency was
proposed for subconsultants.
Based on our evaluation, the estimates are acceptable for contract negotiation. We are providing this memo in
lieu of issuing a pre -audit certificate for this project.
