t INTEROFFICE MEMORANDUM
TO: VILLAGE MANAGER MICHAEL E. JANONIS
FROM: SUPERINTENDENT OF STREETS & BUILDINGS
DATE: JULY 12, 2011
SUBJECT: SEALED BID RESULTS FOR THE REPAIR OF THE POLICE/FIRE
HEADQUARTERS BUILDING PARKING DECK RAMP
(NOT TO EXCEED $194,085)
BACKGROUND
In the current budget, staff has requested funds to repair the ramp portion of the existing
Police /Fire Headquarters Building parking deck ramp. This ramp was constructed in conjunction
with the rest of the Police /Fire Headquarters Building complex in 1993.
The existing electric cable snow melting system failed within 10 years of construction and has
required numerous repairs. Presently, it is not repairable. In order to control the accumulation of
ice and snow on this incline, Public Works crews must mechanically apply salt and de -icing
agents at frequent intervals during the winter season.
Additionally, the garage access control equipment, ramp lighting, and automatic overhead door
are also inoperable; requiring complete replacement.
The proposed repair work includes selective demolition of the existing concrete ramp,
installation of a new hydronic snow -melt system, replacement of the access drive and the ramp
surface topping, and installation of a new access control system.
The Village hired Desman Associates of Chicago, Illinois to design and prepare the bid
documents, oversee the bid opening and supervise construction of the project. Desman is an
architectural engineering firm that specializes in parking structures. The performed design and
construction management services for the Village Hall Parking Deck project.
BID RESULTS
Sealed bids were opened at 1:00 P.M. on June 27, 2011 for proposed work. A bid notice was
placed in the local paper and four concrete construction/restoration firms were invited to
participate.

Two bids were received. The results are as follows:
Bidder Bid Price
Martam Construction Inc., Elgin, IL $ 176,441
Takao Nagai Concrete Restoration, Chicago, IL $ 309,528
Two additional bids were received: one late and one at Public Works. The contract documents
instructed all bidders to submit their bids to the Viiiage Manager's Office at 50 South Emerson
Street prior to 1:00 PM on June 27. Both of these bids were deemed non - responsive and were
returned unopened to the bidders.
DISCUSSION
The low cost proposal was submitted by Martam Construction Inc. of Elgin, Illinois. Martam has
successfully completed a myriad of projects for the Village including bridge deck replacement,
sewer repair and replacement, creek bank stabilization, water main replacement, and streetscape
improvements. They were recently awarded the 2011 Combined /Sanitary Sewer Spot Repair
contract. It is the opinion of staff that Martam is well qualified and sufficiently experienced to
successfully complete this project.
The engineer's estimate of probable cost for this project was $156,169. However, this estimate
was prepared in the initial design phase and the assumptions utilized were changed in the final
bid documents. Specifically, the initial design only required partial removal of the concrete slab
on- grade; the final bid documents stipulated complete replacement. Additionally, the access
control system and the duty rating of the overhead door are more robust than initially proposed.
It is the opinion of staff that these differences in bid requirements satisfactorily explain the
variance between the engineer's estimate and the low bid. Sans these changes, it is probable that
Martam's bid would approximate the engineer's expectations of cost.
Staff recommends including a 10% contingency fee in the award of this project. This
contingency would be reserved for solutions to unanticipated conflicts that arise during the
demolition or construction processes. In this instance, the total recommended award would be
$176,441 (bid) + $17,644 (10% contingency) _ $194,085 (recommended total award).
RECOMMENDATION
Staff recommends accepting the lowest cost proposal as submitted by Martam Construction Inc.
of Elgin, Illinois for repair to the Police /Fire Headquarters Building Parking Deck Ramp in an
amount not to exceed $194,085. Sufficient funds for this proposed project exist in the current
budget.
