Subtask 5.6 - Evaluation of Pipeline Alignment along Everett Avenue. The alternative alignment following Everett Avenue will be developed to the 30 percent complete level. This work will include installation of two additional geotechnical borings on each side of the proposed railroad crossing,surveying and mapping of the new portion of the alignment,contacting utility companies and marking of utilities,preparation of drawings,and preparation of an opinion of probable cost. Design work beyond the 30 percent complete level is included in a previous addendum to the scope of work.

Inspection of Chlorine Contact Channel (CCC). An inspection of the existing CCC will be conducted. This evaluation will consist of inspection of CCC structure(both interior and exterior) and measurement and documentation of cracks. Design of Pump Station to 30 Percent Level. Design of the pump station located on top of the CCC will be completed to the 30 percent complete level. Calculations will be completed for slab thickness. In accordance with the attached letter from the City,we have assumed that the CCC will not need to be upgraded to comply with the current seismic requirements. Drawings showing the pump station layout, structural elements,electrical equipment layout, electrical enclosure building,process& instrumentation,and pipeline alignment will be prepared and submitted to the City for review. In order to minimize design review time, a formal 30 percent review meeting will not be held. Instead,an informal meeting will be held with City staff to review the drawings. Coating Work for the Chlorine Contact Channel. The local representative of the company supplying the coating product used previously by the City(Sherwin Williams)will be 20 4 OF 5
