Title
143rd Street and LaGrange Road Intersection Improvements - Contaminated Soil - RAMSCO, Inc. - Change Order #2
History
At the July Committee and Board meetings, approval was provided to award a contract to RAMSCO, Inc. (RAMSCO) to test, load, manifest, transport and dispose of contaminated soils in an amount not to exceed $119,902.32, with funding coming from a Change Order previously authorized for contaminated soils expenses expected to be borne by Brothers Asphalt Paving, Inc. (Removed $149,463 from Brothers authorization for the RAMSCO work.)
At the September Committee meeting, a Change Order was presented for consideration and approval to add $38,845.20 to the RAMSCO contract for costs associated with increased quantities of contaminated soils resulting from the watermain relocation project, resulting in a new RAMSCO contract value of $158,747.52.
Now that the second of four possible utility relocation projects has been undertaken related to the 143rd Street and LaGrange Road Improvement Project (Watermain and ComEd relocation - Intren, Inc.), further testing, loading, manifesting, transport and disposal of contaminated soils is required. Using the knowledge gained from the watermain project, we now know with greater accuracy the location and extent of the contaminated soils that will require special handling for the electrical utility relocation/burial portion of the overall project. This knowledge has allowed us to recalculate our expected contaminated soils quantities, and the associated costs to remove and dispose of them for each of the following relocation activities.
With the professional management of the contaminated soils provided by RAMSCO related to work associated with the watermain relocation portion of the overall project, and the inherent value in legacy project knowledge now possessed by RAMSCO, it is Staff’s desire to request consideration of a Second Change Order to the RAMSCO contract to manage and dispose of contaminated soils.
Change Order Number 2 is proposed for contaminated soils work required for the disposal of soils generated by Intren, Inc. as they bury overhead electrical lines for the intersection improvement project.
Here, as in other quantity-based requests, the dollar value presented is based upon an estimate of the volume of contaminated soils expected to be excavated and disposed.
Following September Committee Action regarding CHANGE ORDER 1 with RAMSCO, the contract values for RAMSCO consideration of this Change Order Number 2 are as shown in the Exhibit 1 table previously provided as part of the September 7, 2010, Committee Action.
It is Staff’s recommendation that Change Order 2 be authorized to provide additional funding for the contract awarded to RAMSCO, Inc. to test, load, manifest, transport and dispose of contaminated soils that have been found as a part of the electrical utility relocation and burial project at 143rd Street and LaGrange Road in the amount of $25,317.20, yielding an adjusted not-to-exceed value of $184,064.72.
The Village continues to seek full reimbursement for the contaminated soils identified herein as “Village Responsibility” from every current or former operator or landowner that may be contributory to the discovered contamination.
On September 7, 2010, this item was reviewed and approved by the Public Works and Engineering Committee and referred to the Board for approval.

Financial Impact
Funds for the utility relocation costs, as well as the additional items that may arise during relocation construction have been included in the approved Fiscal Year 2010 Budget within the Village’s Capital Improvement Fund. This added cost will not adversely impact the overall utility-related project budget, and the additional cost associated with this RAMSCO, Inc. Change Order Number 2 will keep the total costs associated with this scope of work below the approved budget value.
Recommended Action/Motion
I move to approve authorizing Change Order Number 2 to increase the value of the contract with RAMSCO, Inc. to test, load, manifest, transport and dispose of contaminated soils associated with the 143rd Street and LaGrange Road Watermain Relocation Project in the amount of $25,317.20 for an adjusted not-to-exceed contract value of $184,064.72;
And
Approve authorizing the Village Manager to execute Change Order Number 2 to the contract with RAMSCO, Inc.
