Discussion
The City has received a request from WSB for an increase in the contract amount
for additional engineering services for the above project. The request is attached.
1. Online Bidding Coordination with Quest.cdn. ' $1,700
The City requested that online bidding be utilized for this project.
This was a change of scope from the original contract.
2. Revising the Median Design $ 700
The City requested afield change to allow a median opening to
allow full access (both left and right turns in and ouO for the lot at
the southwest quadrant of the intersection.
3. Additional Construction Services
$4,960
This cost increase was brought to the City's attention after completion of the
project and the assessment hearing had been held. The costs may not be assessed
to the property owners at this time and would come out of the City funds.
Recommendation
Staff recommends that this request be approved; however, staffwill inform' all
Engineering Consultants working on City of Chanhassen projects that in future,
all increases to the not-to-exceed amount must be approved prior to incurring
additional costs to allow an opportunity for cost containment and to allow Council
the opportunity to review and approve the increase.

Additional Construction Services Fee:
The final project scope had several additional construction related items that were not
included in the original feasibility report, which was the basis for our original
construction services fee in our proposal. The following items were above and beyond
the scope of the project as outlined in the feasibility report provided to WSB. The
feasibility report was prepared by a different consultant.
a. Additional fill material was needed to construct the road. This resulted in an
additional 2.5 days (20 hours) of construction observation time.
b. No soil borings were taken as part of the feasibility report. During construction,
marginal soils were encountered that resulted in additional delays (i.e., removing
the soils, additional compaction, etc.). This item resulted in an additional 8 hours
of construction observation time.
c. The revised median design resulted in an additional 3.5 days (28 hours) of
construction observation time due to removal of the old median and installation of
the new median. There were contractor delays in scheduling the curb crew,
additional inspections, etc.
d. Additional survey time to re-stake the median re-design (4 hours).
e. Additional construction project management time for the aboVe-referenced items (8
hours).
Estimated Construction Services Fee Increase .............................................. $4,960
Total Est#hated Fee Increase (Items 1-3) .................................................... $7,360
Attached is a breakdown of the estimated hours used on each task. This would increase our
total design and construction contract to $57,260.
Please review these costs and advise if they are acceptable. I am available at your convenience
to discuss these items in more detail. Please contact me at (763) 287-7195. Thank you.
Sincerely,
