DATE: April 2, 1991 �_ _. - . .. _ .,
SUBJ: Approve Contract Amendment No. 1 HNTB Engineering Services
' Contract on Audubon Road South - Project No. 89-18
This item was presented before the City Council at their regular meeting on
March 25, 1991 and was tabled pending their request for information. It is my
understanding that Council's primary concern was to receive a better explanation
of the reason for the contract amendment and a description of the remaining work
to be completed on the project. Understandably so, it was the Council's feeling
that this was a substantial amendment amount.
Attached you will find two letters from Chet Harrison of HNTB, the project
engineer. The first letter, dated April 2, 1991, describes the need for the
additional services and distinguishes the portion of the contract amendment that
has been actually performed in 1989 and the remaining portion for work to be
completed in 1991. It is apparent that the original contract for services
neglected to account for construction survey staking. This alone accounts for
nearly half of the proposed contract amendment.
The other letter, dated March 28, 1991, spells out the remaining project work
and corresponding engineering services to be completed on the project in the
spring of 1991. This is directly associated with the larger portion of the pro-
posed contract extension amount.
Chet Harrison will be present at the City Council meeting on April 8, 1991 to
discuss these and any other questions or concerns that you or the Council may
have concerning this matter.
If this additional information and tentative discussions at the meeting on
Monday night prove to satisfy the questions raised by the Council, I would
therefore again recommend that the City Council approve amending the Engineering
Services Contract with HNTB for the Audubon Road Improvement Project No. 89-18
establishing a revised ceiling of $65,600.00.

' RE: Audubon Road, City Project 89-18
Dear Mr. Folch:
The original engineer's estimate for professional service for construction did not include costs
for survey construction staking. It only contained survey costs to establish horizontal and
vertical control to be used to do the construction staking.
Survey for control was estimated at 75 hours. The estimated cost to do the construction staking
was 300 hours but was not included in the original estimate. This additional construction staking
' costs accounts for the additional $10,000 spent to date.
The previously approved contract administration costs and inspection are presently within
budget. However, because construction was not completed during the 1990 construction season,
we are requesting an additional $12,500 to complete the contract administration, inspection,
construction staking, record drawing and preparation of assessment costs.
I intend to be present at the April 8th council meeting to answer any questions you may have
regarding past or future anticipated professional engineering fees.

RE: Audubon Road Project No. 89-18
IRevised Engineer Estimate for Construction Services
IDear Mr. Warren:
I have reviewed past, present, and future engineering costs for the referenced project.
IHNTB's letter dated July 26, 1990, provided an estimate of our staffing requirements to
- construct Audubon Road. If the project had been completed during 1990, the estimate for
I project management and inspection would have been adequate to build the street.
However, the estimate to do the construction staking was probably insufficient from the
start. The actual construction staking has taken approximately 340 hours. An additional
1O hours were needed to survey the followin areas: additional slo a stakin on Mi iel
1 propert Araina,.ge ditch design and construction stakin or the new drairaagg ditciulong
L man Road additional cross sections an s o•e stakin. on the Basins •ro•e design
I survey and construction staking for new storm sewer north of Heron Drive, and additional
slope staking required on the Stockdale property.

Based on the fact that the construction extended beyond October 15, 1990 and the fact that
the project will not be completed until June, 1991, we are requesting that our construction '
engineering contract be increased to $65,600. We are presently studying the intersection
ca acity and level of sere-ior Audubon Road and Heron Drive as an additional
transportation planning service (Estimated Study Cost $1,000.00). '

1 RE: Audubon Road South - Upgrade; City Project No. 89-18
Dear Mr. Warren:
1 With the award to Imperial Developers, Inc., we would like to proceed into the construction phase
for the project. We propose that the compensation will be on a cost plus with a maximum. We
have attached a description of the proposed person hour estimate and fees. The estimated hours for
1 Construction Inspection are based on a full-time Resident Project Representative (as described in an
Appendix "B" of the contract) on the site for about 11 weeks and periodic visits by office personnel
for inspection of utility construction. We will request, if necessary, additional funds if the
maximum amount is exceeded in the future.. We also have enclosed a-copy of correspondence
1 indicating our latest overhead rate which is slightly higher than last years overhead rate. The
multiplier, using the new overhead rate is 2.69 [(134.24% + 100%) x 1.15].
1 Regarding the additional services for preparation
as pre aration of easements, we estimate
total amount spent

We have forwarded the contracts to Imperial Developers, Inc. in a separate letter dated July 25,

Unless you have any objections, we will proceed to contact GME Consultants, Inc. and have them
perform the necessary construction and density testing. GME will bill you directly for their

Please contact us if you have any questions or comments.
