TO: Terracon Consultants, Inc., HW687 Contract File

FROM: Megan Johnson, Contract Manager

DATE: March 5, 2024

SUBJECT: Negotiation Summary – BIL22 Task Assignment (TA) Change Order #2 – TA BIL02AC2 Broward County School Board Property – Site ID # ERIC_18360 Supplemental Site Assessment Activities

This Task Assignment Change Order (TACO) is for the correction of the subcontractor costs under Subtask 3. Specific changes are detailed below:

Subtask 3: Initial Supplemental Site Assessment Activities Changes in cost associated with this Subtask are due to a correction of the subcontractor costs following execution of the previous TACO. It was discovered upon invoicing that a draft version of the subcontractor invoice was used to write the previous TACO, and not the final subcontractor invoice. This resulted in a cost actual decrease of ($341.00).

Summary The Department’s BIL Contract Manager and Terracon’s Contract Manager have both agreed to the above changes. All changes noted above represent a total overall cost decrease of ($341.00), as shown in the Delta and Cost Actual CEF/LOE. The changes were noted in the TACO Request received from Terracon on February 29, 2024. The final cost associated with this TA decreased from $130,045.09 to $129,704.09. Documentation of the changes is included in the attached TACO Request, the Delta LOE spreadsheet and the Cost Actual LOE spreadsheet, and the TACO form for BIL02AC2 prepared by the Department.

Shawn, Subtask 4 is good to go and can be invoiced for now if Terracon wants to do that.

However, Subtask 3 will require a Change Order to reflect the correct costs prior to invoicing.

Hi Ben, My apologies It appears we had used a draft version of the Sub invoice to draft the CO and it carried through.

Is there a way to reconcile the $310 overage without another change order? We had a recently processed al change order and there most likely will be another reconciliation before final bill as IDW typically never matches exactly to estimates.

Thanks, Shawn Ouellette Senior Geologist, P.G. Environmental Division
