Subject: Negotiation Summary

HW682 DC009A-01

This Task Assignment Change Order authorizes an increase in costs to reconcile Work Change Directives 1-6, which include changes in labor, travel, subcontractor, laboratory and equipment costs due to the following:

WCD 1: addition of 28 labor hours that were originally scoped but left out of the Formula Sheet/total cost of original TA; switch the groundwater and soil lab analyses from 8260 VOHs to 8260 full list in subtasks 3 & 4; additional shipment costs to accommodate those hold times (*Note - lab costs actually decreased due to less samples needed [SPLP and missing monitor wells]).

WCD 2: the addition of encore samplers in subtask 3, the addition of personnel (and therefore travel/vehicle costs) in subtask 3; increases in hotel costs in Miami in Subtasks 3-6; addition of a survey kit in subtask 4

WCD 3 & 4: increase in drilling costs for additional well installations in subtasks 3&4 (these additional costs were unnecessary and unused)

WCD 5: addition of subcontractor costs to provide MAGS equipment in Subtask 5.

WCD 6: additional labor hours, laboratory and equipment costs to sample the two new/ additional wells in Subtask 4.

Drilling costs that were expected to increase in Subtasks 3 & 4 and authorized in WCDs 3 & 4 ended up actually decreasing due to unused time and materials.

This TACO also includes a time extension to account for multiple project delays resulting from the need for replacement wells and issues scheduling/performing MAGS testing with GHD. Additionally, time is also being added due to recent delays in IDW pick up.

These changes result in overall cost increase of $9,007.77 (with a $0.02 delta rounding error). The FDEP project manager agrees to the scope of work and final cost associated with this Task Assignment which is $103,403.27 with 323 total labor hours.

In SubTask 3 the FDEP agreed to move a proposed soil boring from within the right of way of SW 61St Avenue to two locations across the street. The since submitted the original proposal the FDEP has requested 8260 full list instead of 8260 VOHs and ECT has requests the cost difference to change to 8260 full list analysis in SubTask 3 and 4. Additionally, sample shipments were added to ship soil sample each day (5-day event) to meet the 8260 hold times and a groundwater sampling kit was added to SubTask 3. There was an error in the Cost Estimate Formula Sheet that affect the total labor dollars in SubTask 8.

In SubTask 3, additional three additional DPT groundwater sampling, three 8260 full list samples and 127 soil and groundwater samples are requested to be changed form 8260 VOHs to full list. Additionally, three sample shipments are included for SubTask 3 so that samples can be shipped each day of the 5 days scoped to meet the 8260 soil hold time requirement. Since groundwater sampling is also included in SubTask 3 a groundwater sampling kit has been included. SubTask 4 has 15 samples change from 8260 VOHs to full list. The Cost Estimate Formula Sheet was not calculating the total hours that were presented on the Cost Estimate sheet which did not account for all of the labor costs for SubTask 8.This error also affected the project management hours.

Attached are figure showing the new DPT locations and the old location in the right-of-way. Additionally, attached is the original, corrected CELOE worksheets and a summary CELOE for the cost increases.

SubTask 1: Project Management MC 1.6 hours

SubTask 3: Soil Sampling; Three DPT groundwater samples $36.00, three additional 8260 full list $110.00 unit rate, total cost $330.00, 97 samples for 8260 soil and groundwater change from VOHs to full list $3,589, 3 sample shipments $210.00, and a groundwater sampling kit $290.00

SubTask 4: Groundwater Sampling; 14 samples change form 8260 VOHs to full list $518.00.

SubTask 8 SAR; Hours missing from the Direct Labor total were GS 2-hours, KM 20-hours, and JV 8-hours.

In SubTasks 3 and 4 Groundwater Protection Inc (GPI). is requesting an increase in the drilling cost due to the time of the original quote and the increase of economic costs. Additionally, it was noticed that Encore Samplers were missing from Task Assignment for SubTasks 3 and 4 which is included in this Work Change Directive (WCD). An increase in hotel room rate due to current cost in Miami. Due to the scope of work ECT is requesting an additional person to collect samples in SubTask 3 and associated costs for that person to be out of town. A survey Kit was added to SubTask 4 to identify the groundwater flow direction at the site prior to the PLS. These proposed changes increase the project management cost.

GPI recently informed ECT the drilling cost increase occurred on January 1, 2023, and ECT was neglected to be informed. As a result, ECT is requesting the GPI drilling cost increases for SubTasks 3 and 4. A drilling cost summary and the original and update quotes are included in the Attachment. It was noted that Encore Samplers for Synthetic Precipitation Leaching Procedure were omitted from the original proposal and 20 units are included for SubTask 3, and 10 units are included in SubTask 4. Given the number of samples required for SubTask 3, ECT is requesting the Senior Scientist time be extended to stay from Monday through Wednesday to help with the sampling. Hotel, per diem, and additional car units have been included for the Senior Scientist. The hotel cost in Miami has increased since submitting the original proposal and hotel cost differences for employees in SubTasks 3 and 4 have been increased by $15 per night. A unit for a Survey Kit has been added to SubTask 4 to be able to determine the groundwater flow direction prior to scheduling the PLS.

Attached is the GPI Drilling cost summary table, the original and revised drilling quotes.

SubTask 1: Project Management MC 1.8 hours.

SubTask 3: 20 hours, Vehicle, per diem, and hotel for Senior Scientist DP; hotel rate increase of $60 for KM; GPI cost increase of $745.00; and 20 Encore samples for $160.

SubTask 4: Hotel increases for KM, JP, and BC is $120; GPI drilling increase of $1,200; 10 Encore Samples for $160, a survey Kit for $50. Groundwater Protection Inc., drilling cost increase of $2,784.

SubTask 5 Hotel increase for JP and BC is $30.

SubTask 6 Hotel increase for JP is $15.
