  SCHEDULING REQUIREMENTS


The RJN Team approach is designed to fulfill the goals of this project using the most appropriate inspection technique while considering cost implications. With a compliance commitment of July 31, 2005, our approach considers managing three concurrent projects. The key aspects for developing the schedule include the following:

Exposed manhole in the SAWS system

1. Manhole Inspection - Manhole inspection, consisting of manned personnel descent of 1,000 manholes and video inspection of approximately 80 other manholes was completed in 2003.
2. Televised Inspection - Television inspection of over 315,000 linear feet of sewer main was completed in 2003. This inspection yielded approximately 60,000 feet of sewer main requiring some type of mainline rehabilitation and 240 isolated main/service repairs (point repairs).
3. Design Schedule - Initial Design of the project consisted of finalizing recommendations for each of the pipe segments identified with a defect that could cause exfiltration from the system. Once the recommendations were finalized, those segments identified for cured in place rehabilitation and pipe bursting were designed for work orders utilizing the SAWS established term contracts. Survey was secured for the open cut segments and design was prepared. The point repair and remaining cured in place pipe improvements (beyond the available term contract amount), were mapped and bid documents were prepared. The design effort was essentially complete by March, 2004.
4. Construction Schedule - The construction effort was broken into multiple contracts due to the overall size of the project, the specialized techniques associated with trenchless rehabilitation and the goal of completing the project by mid 2005. The first two construction packages were released in July, 2004 – Open Cut Phase 1 and CIPP Phase IV. The remaining construction packages should be released to contractors by November, 2004.

Upon completion of the project, RJN will provide SAWS a complete database documenting the inspection results, the improvements completed and certified, and certification by a registered professional engineer that the inspection and improvements are in conformance with the requirements of the Chapter 213 regulations.

  PUBLIC INVOLVEMENT

Due to the sensitivity of this project and the various locations of the project segments, it is imperative that the public be a partner in this project. SAWS has worked diligently over the first half of 2004 to notify Homeowner Associations and other interested individuals of the impacts of this project and the need to protect the Aquifer. A copy of an abbreviated version of the presentation is provided below. If you are interested in SAWS providing a presentation to your Homeowner Association or group, please contact .
