Title
Consider a resolution authorizing the Mayor to execute Supplemental Contract No. 4 with Plummer and Associates, Inc. for the BCRWWS East WWTP Tertiary Filters Preliminary Engineering Report (PER).
Body
Brushy Creek Regional Wastewater System (BCRWWS) is expanding the capacity of the East Regional Wastewater Treatment Plant (WWTP) to 30 million gallons per day (MGD). As a result of the increased capacity of the WWTP, the Texas Commission on Environmental Quality (TCEQ) could possibly place more stringent limitations on effluent quality both now and in the future. To ensure the effluent quality standards are met, the partner Cities have decided to construct tertiary effluent filters which will add 48 MGD of capacity to the 6 MGD of existing filter capacity. In total, the plant will have 54 MGD of filter capacity at the completion of this project.
Plummer and Associates, Inc. designed the project and is currently providing construction phase services. The construction contract was awarded to Keeley Construction Group, Inc. in July 2024 and is actively under construction. Construction has extended past the original contract time, and additional construction phase services are needed to support the project.
This request is for the approval of Supplemental Agreement No. 4 with Plummer and Associates, Inc. for additional construction phase services, including submittal review, project meetings, and other services to support the project through the end of construction. The total cost of Supplemental Agreement No. 4 is $137,569.00. The City of Round Rock cost allocation based on 60.76% treatment plant capacity ownership is $83,586.92.
Cost: $137,569.00
