Body
Staff Recommendation
Approve the Resolution.
Fiscal Impact
Staff is proposing to use savings from the 2019 Street Resurfacing projects which are substantially compete to fund this change order. The two 2019 local street resurfacing projects are nearing completion and will be completed approximately $70,000 under budget.
The street resurfacing projects and the bridge rehabilitation project are being funded through the FY2018 Capital Improvement Fund, Public Works-Engineering, Local Street Construction account no. 3095-43780-101-570951 and a budget amendment will not be required to move funds in the same account.
Background
In September the Village approved a construction contract with Norvilla for repairs to the Oak Park Avenue Bridge over I290 and the installation of wood shielding under the Home Avenue Bridge. Work is underway on this project and due to unanticipated conditions for rotting existing wood shielding and the condition of the sidewalks over the CTA tracks, change orders are required in order for this project.
The existing protective wood shielding under the west sidewalk on the Oak Park Avenue Bridge over I290 has rotten and will need to be replaced in order for these sidewalk to be patched. The wood shielding protects drivers on I-290 from falling debris during. This change order includes $34,090 to remove and replace the deteriorated existing wood shielding.
The original design of the project only included partial depth repairs to the sidewalks on the Oak Park Avenue Bridge over the CTA tracks based. Upon final inspection of the bridge this fall areas of full depth sidewalk replacement were identified which requires additional work and additional railroad flagging. This change order includes $30,700 for the work for the full depth patching and CTA flagging associated with these repairs.
These additions to scope were authorized during construction since the work is required and so that the work could proceed and be completed this season.
