Title
143rd and LaGrange Road Intersection Improvement Project
Supplement 1 - V3 Companies: Construction Management
History
On February 4, 2009, a scope and fee proposal was received from V3 to provide professional Construction Management services. At the time this proposal was received no actual construction work had commenced, but the first of the ensuing projects to install new watermains outside of the new roadway intersection footprint was being actively bid. The V3 proposal was approved at the February 16, 2009, Board meeting.
Since then, numerous advance utility relocation projects were undertaken in 2010, including the watermain project, as well as the undergrounding of ComEd, AT & T, and Comcast overhead utility lines, and the installation of new natural gas mains and services in the same area. All five of these projects have gone smoothly despite many, many challenges.
The more significant challenges came with the watermain work, as expected, as that was the first project to break the surface of very old, well and diversely used, current and former business sites. Though not totally unexpected, contaminated soils were found scattered about the watermain work zone which required intense oversight and control. While the contaminated soils needs were being reviewed and resolved, the contractor was asked to move to other areas of the project to keep production moving. Ultimately, the watermain joints and seals in the areas of contamination required very expensive petroleum-resistant seals and gaskets. There was also added control and oversight to ensure that contaminated soils were properly tested and segregated to enable the Village to be properly positioned to back-charge companies that polluted the soil. Please also remember that this project was awarded to a low-bid contractor that had ventured into somewhat unfamiliar territory in that a company established as an asphalt paving contractor was doing underground watermain work.
