Title
Consider a resolution authorizing the Mayor to execute Supplemental Contract No. 1 with Alan Plummer Associates, Inc. for the BCRWWS East Wastewater Treatment Plant Expansion (Construction Phase Services) Project.
Body
The Brushy Creek Regional Wastewater System (BCRWWS) East Wastewater Treatment Plant (WWTP) is owned by the Cities of Round Rock, Austin, and Cedar Park. The City of Leander is buying into the BCRWWS by cost participating in the expansion project. This project expands the BCRWWS East WWTP capacity from 20 million gallons per day (MGD) to 30 MGD and upgrades the plant’s ability to treat to a higher level to meet potential stricter Texas Commission on Environmental Quality (TCEQ) permit requirements. Most, if not all, of the existing plant improvements, were driven by the expansion of the plant to 30 MGD.
The City entered into a contract with Alan Plummer Associates, Inc. (APAI) on August 10, 2017, in the amount of $1,662,593 to perform the preliminary engineering services necessary for the expansion of the BCRWWS East WWTP.
Supplemental Agreement No. 1 with APAI added additional services, which included surveying, geotechnical data collection, and equipment pre-selection services. These tasks were not included in the preliminary engineering and were needed before beginning the final design. Equipment pre-selection established specific products and manufacturers for almost all of the large equipment to be installed and constructed with the plant expansion project. Supplemental Contract No. 1 was $500,000, bringing the total engineering for the project to $2,162,593.
Supplemental Contract No. 2 for Final Design for $7,909,514 has been completed. The contract also included bidding phase services. Total engineering costs approved through the bidding phase was $10,072,107. APAI (now Plummer & Associates) has two primary engineering sub-consultants under these agreements. They are with K. Friese and Associates (KFA) and Freese and Nichols, Inc. (FNI). The breakdown of costs and tasks for these services were shown in the contract documents.
A new contract was entered into with Plummer & Associates to provide construction phase services for the expansion project. It included, amongst other services, providing two full-time onsite people to perform construction oversight on behalf of the owners. Other primary functions included processing requests for information and change orders from the contractor, equipment and materials testing, day-to-day and final walk-through inspections, and approving as-built plans. It was anticipated that these services were needed thru the end of the construction project, which was anticipated to last three years until June 2023.
Because the project is taking longer to complete due to scope increases as well as the contractor taking additional time, this Supplemental Agreement No. 1 is needed for extending the Construction Phase Services which will continue the scope of services by the two full-time Plummer personnel through the end of substantial completion. The services of these personnel will continue to assist staff with day-to-day inspections, field reporting, and review of payment applications. These services will be needed a short time longer, through the end of September 2023.
The City of Round Rock has been managing this project on behalf of all the partner cities. The City of Round Rock’s cost share in the project is 12%. This Supplemental Agreement No. 1 is for $144,715.11. Therefore, the City’s share of the engineering for this contract is $609,187.33 of the total contract amount of $5,076,561.11.
Cost: $144,715.11
