Title
Relocation/Burial of Electric Service Lines - 143rd Street and LaGrange Road - Board Approval
History
In order for the proposed improvements to be constructed at the intersection of 143rd Street and LaGrange Road, all existing utilities in conflict with the new intersection roadway configuration must be relocated to an area that will avoid conflicts with the final intersection and roadway. Engineering to date has identified known conflicts and they include Village-owned watermain and water service taps, Commonwealth Edison (ComEd) facilities, NICOR gas facilities and overhead transmission lines owned by others including cable television.
As the schedule moves forward for the intersection and roadway improvements, conflicting and aging utilities are being relocated and replaced to ensure that once completed no further construction will be required in the project area. On December 21, 2009, the Village Board approved awarding a contract for the first of the utility relocations: a watermain replacement and relocation in the amount of $1,233,482. This work is expected to begin during the first quarter of 2010, and be completed near the end of the first quarter.
Keeping the project moving, the next utility relocation is a significant piece - the relocation and burial of the ComEd transmission and service facilities that exist in the project area.
During 2009, several meetings were held with staff, engineers and representatives of ComEd whereupon another request was made of ComEd to provide cost estimates to the Village for engineering and construction required to relocate their facilities that are in conflict with the proposed Village improvements in the project area. Previous cost estimates for the relocation work were provided to the Village during March and April of 2009 for budget and planning purposes.
On November 16, 2009, an updated cost and general scope of services for the relocation was received by the Village from ComEd and reviewed with staff and engineers, with a total cost for construction and engineering of $5,511,500. January 4, 2010, staff and engineers met with ComEd representatives and others including McDonough Associates Inc. (engineers selected by Illinois Department of Transportation for Phase 2 engineering on the LaGrange Road Corridor) regarding work planned for this project and the corridor. Staff and ComEd discussed design engineering costs and agreed that the design engineering costs for the utility relocation work consisted of approximately five percent (5%) of the total costs provided in the November estimate. As the Village plans to request bids for significant intersection and roadway improvements for the project in July 2010, it is in the best interest of the Village that the known utility conflicts be mitigated before bids for upcoming work are requested to minimize risk of delay to the bidders. Following review of the scope and costs, it is recommended by staff and engineers that the Village proceed at once with the ComEd utility relocation work. The design engineering costs are projected to be approximately $275,575.
ComEd is required to relocate their facilities that are in conflict with Village roadway improvements, however, the Village is obligated to reimburse the utility (ComEd in this case) for their costs incurred due to the relocation required. With this project, the Village is also asking that the overhead facilities be relocated underground as well.
On January 11, 2010, this item was reviewed and approved by the Public Works and Engineering Committee and referred to the Board for approval.
INFORMATION PREVIOUSLY PROVIDED AS PART OF THE JANUARY 11, 2010, PUBLIC WORKS AND ENGINEERING COMMITTEE PACKET.
Financial Impact
The 2010 budget contains $5,807,500 for the relocation/burial of the overhead electrical lines, and the current aggregate cost for the work required to relocate and bury the electric lines and facilities in the project area is within the adopted budget.
Recommended Action/Motion
I move to approve authorizing an expenditure to Commonwealth Edison Company for design engineering services required for the relocation and burial of Commonwealth Edison electrical transmission and service lines located within the limits of the 143rd Street and LaGrange Road intersection improvement project for an amount not to exceed $275,575;
And
Approve authorizing the Director of Public Works to provide an unconditional Notice to Proceed to Commonwealth Edison for the required design engineering services;
And
Approve authorizing the Village Manager to execute the agreement.
