The Engineering Department recommends approval of an expenditure in the amount of $170,944 for construction materials testing professional services from Raba Kistner, Inc. for Water Rehabilitation - Los Rios Addition and Ranch Estates, Project No. ENG-CMB-00005. The project scope entails the removal and replacement of approximately 12,150 linear feet of existing 6-inch and 8-inch waterlines, along with associated pavement reconstruction and the installation of barrier-free ramps.
Raba Kistner, Inc. was deemed most qualified based on their Statement of Qualifications submission to RFQ No. 2021-0378-XR. Raba Kistner, Inc. also has successful experience with the City of Plano Engineering Department in providing construction materials testing professional services for projects with similar scope with concrete pavement testing, field density testing for waterline trench compaction, etc. They are currently working on Water Rehabilitation - Park Boulevard Phase 2 (US 75 to East City Limits), Project No. 7592, with the Engineering Department.
The benefit of this project includes verification that the materials furnished and installed by the Contractor meet or exceed project specifications and City standards.
Not approving the expenditure would result in limiting the Contractor's accountability to provide materials meeting the specified project requirements, potentially reducing the quality of materials placed and the infrastructure's service life.
