RE: Contract No. 1802575
GLWA Conveyance System Engineering Services
Vendor: Brown and Caldwell, LLC
MOTION
Upon recommendation of Cheryl Porter, Chief Operating Officer - Water and Field Services, the Board of Directors (Board) of the Great Lakes Water Authority (GLWA), authorizes the Chief Executive Officer (CEO) to enter into Contract No. 1802575 “GLWA Conveyance System Engineering Services” with Brown and Caldwell, LLC, at a cost not to exceed $3,149,897.00 for a duration of 36 months; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
The GLWA sewer system (approximately 180 miles of sewers ranging from 48” through 168”) is 80 years old on an average, with much of the infrastructure more than 100 years old. These sewers have been constructed in various phases under various contracts using bricks or concrete. Due to the age and various deterioration of these aging sewer pipes, immediate repair and/or rehabilitation is often required.
JUSTIFICATION
GLWA recently conducted a global inspection of the sewer interceptor system under contract GLWA-CON-149 “Emergency Sewer Repair” to determine their condition and to identify areas of severe distress that require repairs and/or rehabilitation. Contract No. 1802575 builds upon that inspection by providing engineering services to evaluate the inspection results and recommend the best rehabilitation method. Also, the consultant will design and prepare bid packages for the construction contracts. Such design includes collecting additional data (structural and geotechnical), performing analysis of the conditions, developing feasible alternatives, working with GLWA to select the best alternative, completing the design, assisting with procurement, and providing oversight of the construction.
Project Objectives
The project tasks are described as follows:
A. Review Pipeline Assessment Certification Program (PACP) Reports, CCTV, and Historical As-built Drawings
B. Manual Inspection of Sewers, if necessary
C. Rehabilitation/Repair Evaluation and Option Analysis
D. Flow Control Design
E. Preparation of Construction Documents
F. Construction Assistance
