HDR Engineering, Inc. (HDR) provided engineering design services to the Clark County Water Reclamation District (District), Las Vegas, Nevada, to rehabilitate a number of pipelines within their jurisdiction. Phases 1 and 2 included priority pipes selected by the District's operations and engineering staff. These projects are part of a larger effort by the District to rehabilitate several miles of sewer pipelines in the District's service area. The District owns and maintains over 2,700 miles of pipeline; portions of which have been in service for almost 50 years. Rehabilitation technologies primarily focused on cured-in-place pipe (CIPP) for pipeline rehabilitation and cured-in-place manhole (CIPM) liners for access structures to provide a rehabilitation solution that provided another 50 years of service.

Beginning in February 2004, the Clark County Water Reclamation District began rehabilitation design of sewers along Tropicana Avenue and Flamingo Road, two of the heaviest traveled roads in the Las Vegas Casino Resort Area. In February 2005, design of the Phase 2 design at various locations in the county was started. While Phase 1 was under construction, Phase 2 pipes were in the design phase. A number of issues related to contract documents were identified during Phase 1 construction that benefited Phase 2 design. These issues are discussed to benefit future rehabilitation designs allowing sequential design, construct, design projects to provide the pathway for rehabilitation design improvements. The issues represent just a few of the numerous issues that arose during the Phase 1 construction and Phase 2 design.

Reliable rehabilitation contract documents aid contractors in providing reasonable and accurate bids. The more issues that a design engineer can identify during the design phase to provide appropriate mitigation in the contract documents will greatly enhance the contractor's ability to provide cost-competitive bids for rehabilitation work, while providing satisfactory contract documents to both Owners and Contractors.
