SUBJECT:
Resolution authorizing the Director of Purchasing and City Clerk to execute the Contract Amendment with Wills Burke Kelsey Associates, Ltd. (WBK) for the Lake Street Sewer Separation Construction Engineering Services.
PURPOSE:
To increase the Contract amount by $34,200 from the original value of $85,000 to a new Contract amount of $119,200.
BACKGROUND:
This change order is necessary to increase the Contract value to address circumstances that were unknown when the original Contract was developed. During the final permitting of the project with the Illinois Department of Transportation (IDOT), the scope of work was increased to include complete pavement reconstruction for the east half of Lake Street from Cross Street to Downer Place. This increase in work added significant time to construction schedule; in order to ensure adherence to specifications and construction methodology, on-site construction engineering was required for the lengthened construction schedule; therefore, it was requested that WBK submit a Contract Amendment to account for the additional on-site construction engineering hours; this Amendment is attached as Exhibit 'A'. .
DISCUSSION:
Based on final permit review comments, the east half of the roadway was completely reconstructed with new curb and gutter and sidewalk within the limits of the sewer separation project (Cross Street north to Downer Place). Completing the pavement improvements with the sewer separation provided an overall cost savings to the City and will allow for expedited construction during the upcoming River-Lake Street Two-Way Conversion Project. The 2015 Budget has funds for this work in Project IB018 Account Number 510-4063-511-7314.
IMPACT STATEMENT:
Increasing this Contract will allow for the On-Site Construction Engineering required to adequately perform construction observati...
