Title
Approving a professional services supplemental agreement No. 1 with Quiddity Engineering, LLC, in the amount of $557,144, associated with the Rehabilitation of Wastewater Lines, and authorizing the City Manager to execute the same.
Summary
The Rehabilitation of Wastewater Lines (WW2306) was identified in the Wastewater Master Plan as a necessary rehabilitation of the existing 30+ year old gravity wastewater lines in the Gatlinburg and Bohls Place neighborhoods. As part of Project No. WW2306 Rehabilitation of Wastewater Lines, the City desires to rehabilitate the wastewater lines within the Gatlinburg neighborhood to reduce and eliminate inflow and infiltration (I&I). The City recently completed cleaning and televising within the Gatlinburg neighborhood and identified several segments to be removed and replaced, along with manhole rehabilitation. The proposal includes professional services for final design, bidding, surveying, geotechnical, and environmental services for approximately 4,400 LF of 8”-12” sewer and 60 manholes. The project also includes cleaning and televising, and smoke testing of the Bohls neighborhood to identify defects to reduce and eliminate I&I. The proposal also includes professional services to prepare a cleaning, televising, and smoke testing bid package, solicitation, bid, coordination while services are being completed, review of results, and assembly of a preliminary engineering report recommending the types of rehabilitation needed for approximately 25,477 LF of sewers ranging in size from 6”-8”, and approximately 70 sewer manholes.
This item supports the Residential and Node Development pillar of the Strategic Plan by improving the City’s infrastructure in existing neighborhoods to serve both current and future Pflugerville residents.
