In 2018, staff engaged Gewalt Hamilton Associates (GHA) of Vernon Hills, Illinois to help obtain an Illinois Department
of Transportation (IDOT) permit and develop bid documents necessary to construct grade -level pedestrian crossing
improvements at the intersection of Main Street (IL Route 83) and Busse Avenue. An IDOT permit is necessary for
this improvement because Main Street (IL Route 83) is owned by the State of Illinois.
The total cost of engineering work on this project in 2018 and 2019 is $9,790.24.
The scope of work completed to date includes development of IDOT permit application plans and specifications for the
construction of a pedestrian crosswalk on the north leg of the intersection. Design features include a center refuge
island, overhead signs, pavement markings, advanced warning signage, and American with Disabilities Act (ADA)
compliant sidewalk ramps. In addition, GHA has submitted several design iterations to IDOT in order to satisfy ADA
slope requirements on the sidewalk approach to the new crossing on the northwest corner of the intersection (directly
in front of the Station 34 restaurant).
GHA has also developed alternative concepts for IDOT's consideration. One (1) idea subject to considerable discourse
with IDOT included moving the crosswalk further north to explore whether a left turn lane for southbound traffic could
be accommodated. Regrettably, the effort was not fruitful but, nonetheless, required an unanticipated application of
GHA resources.
Obtaining an IDOT permit to construct an at -grade pedestrian crossing at Main Street and Busse Avenue still requires
more engineering work. The additional scope of work includes drawing revisions, finalization of bid documents and
plans, incorporation of new topography from the west leg of the intersection, additional revisions to the curb line on
the southeast side of the intersection, as well as a design for a 3/4 pork chop on the east leg of the intersection to
restrict left turns from southbound Main to eastbound Busse while still allowing left turns from westbound Busse to
southbound Main. A rather significant engineering challenge is constructing the improvements to satisfy current ADA
requirements.

Staff has asked Gewalt Hamilton Associates for a supplemental proposal to complete the work. Subject proposal is
attached. Although the cost of this supplemental proposal ($12,794) is within the Village Manager's discretionary
authority to expend funds, staff is forwarding this matter for the Village Board's consideration because this proposed
expenditure exceeds $20,000 (the Village Manager's spending authority) for a single project, to a single vendor, when
combined with the initial 2018 PO ($9,790.25).
It is the opinion of staff that GHA is uniquely well qualified to complete remaining design work due to the firm's
extensive involvement in the development and refinement of the project to date. Furthermore, staff also finds GHA's
requested fee ($12,794) and allotted work effort (103 hours) reasonable. The hourly rate for this type of professional
engineering service ($124/hour) is competitive.
Alternatives
1. Accept proposal from Gewalt Hamilton Associates for Main Street and Busse Avenue pedestrian crossing
improvements deign engineering.
2. Action at discretion of Village Board.
Staff Recommendation
Staff recommends that the Village Board accept the proposal from Gewalt Hamilton Associations of Vernon Hills,
Illinois for the Main Street and Busse Avenue Pedestrian Crossing Improvements Project design engineering services
in an amount not to exceed $12,794.
