Sarasota County, FL

Ardurra provided route evaluations, preliminary engineering, design, permitting, and construction management services for 5 miles of 48-inch and 1 mile of 36-inch potable water transmission main including steel casings under water crossings, an aerial crossing, and a meter station with SCADA. The project also included preliminary design, property evaluations and determination of potential sites for a ground storage tank and booster pump station.

Preliminary engineering included working with the Authority and Sarasota County to evaluate demands, delivery pressures, and delivery points; hydraulic modeling of the proposed pipeline, the County’s water system and the future Phases 3C and 3D pipelines to size the pipe and evaluate the need and/or location for a storage tank and/or re-pump station; and route evaluations for the Phase 3B pipeline (and the Phase 3C pipeline from Clark to Fruitville Road) to determine means of routing around the County’s Dona Bay project and to allow for proper connection of the Phase 3C project and a proposed 30” water main by Sarasota County, connecting the Phase 3C pipeline with Sarasota County’s Pump Station No. 5.

Ardurra also developed a report outlining conceptual booster pump station site plans and available land/sites for its future construction. Ardurra identified and evaluated potential routes for the pipeline and identified land acquisition and permitting requirements. Resulting information and recommendations were compiled and reported in the Basis of Design Report submitted to the Authority.

Subsequently, Ardurra provided final design, permitting, and construction management services for 5 miles of 48-inch and 1 mile of 36-inch potable water transmission main including steel casings under water crossings, an aerial crossing, and a meter station with SCADA.

As part of preparing the project for construction, Ardurra developed a Prequalification Package defining minimum experience and other requirements for contractors and directional drill contractors to bid the job. Ardurra then assisted with review of the submitted information and with prequalifying contractors to bid on the project.

The project was completed under budget due to non-use of Contingency Allowance and other bid items such as borrow material. Familiarity between Owner, Contractor, and Engineer, coupled with favorable weather conditions and well-written, clear set of bidding documents resulted in an on-schedule completion.
