Title
143rd Street Watermain Engineering Design (Phase II) - Proposals
History
Over the last several years, McDonough Associates Inc. (MAI) of Chicago, Illinois, has been performing engineering services for the 143rd Street Corridor from Southwest Highway to Will/Cook Road. In June 2011, the Village Board approved continuing this effort. Phase II design for the segment from Wolf Road to Will/Cook Road along with the completion of Phase I engineering from Southwest Highway to Wolf Road were approved. Also included was engineering to reconfigure the intersection of 143rd Street and Southwest Highway.
Within this area (Southwest Highway to Will/Cook Road), several segments of watermain are in need of replacement due to age, condition and/or size. Additionally, sections of new watermain will be added to fill gaps and improve flow throughout the corridor.
To correspond with the roadway design work, three proposals were requested. Additionally, two options were requested. One option is for complete bid specifications with watermain installation in advance of roadway construction (permit project). The other option is for engineering specifications only, with installation as part of the roadway widening, within the Illinois Department of Transportation (IDOT) project. To maintain more control over the installation, it is Staff’s recommendation to complete the work within Segments 1A and 1B in advance of IDOT, as a permit project. Due to the extensive unstable soil within Segment 2, the watermain installation should be completed as part of the road construction, within the IDOT contract. This method will allow the watermain installation to occur within the stabilized right of way provided by the roadway construction.
Segment 1A
$29,000.00 - 143rd Street at Southwest Highway to Union Avenue
Segment 1B
$70,900.00 - 143rd Street from Union Avenue to Wolf Road
Segment 2
$40,305.55 - 143rd Street from Wolf Road to Will/Cook Road
On December 19, 2011, this item was reviewed and approved by the Public Works and Engineering Committee and referred to the Board for approval.
