(ELK) to provide corrosion engineering services for Baird, Hampton & Brown, Inc. (BHB) for the afore-mentioned project. As we understand the project, BH8 has developed: plans for approximately 2,725 ft. of 24" water line to be constructed of coated and welded steel pipe, concrete cylinder pipe, or ductile iron pipe and 1,816 ft. of 16" pipe constructed of either ductile iron or concrete cylinder pipe. ELK's responsibility will be to determine the best method to achieve corrosion control for this project. We propose the following Scope of Work for this project. 1. SCOPE OF WORK A. Design Services 1 . All design work shall be under the direction of a licensed PE JX)with dual accreditation by NACE International as a Corrosion Specialist and a Cathodic Protection Specialist.

A representative from ELK will drive the proposed pipeline right-of- way (ROW) to perform the following tasks. Proposal 08-1 108 Rev 2 09 December 2008 Replacement Contract WSM-1 Page 2 i Measure the soil resistivity (SR) at selected locations. The SR tests will be performed using the Wenner 4-pin test procedure. Pin spacing depths of 2.5, 5, 10, 15, and 20 feet per test will be used at each test location. ii Measure the soil pH with a standard antimony electrode, a copper/copper sulphate reference electrode, and a digital D.C. multimeter such as a Fluke Model 87 or equivalent. iii Look for signs of steel or iron foreign line crossings with cathodic protection, i.e. regulated natural gas lines, gasoline lines, and oil pipelines. b. Office Investigations i ELK will review the preliminary design documents and any soil boring logs that may have been provided by other members of the design team, c. After a thorough review of the documents, ELK will perform design calculations for coated and welded steel pipe, poly-bagged ductile iron pipe, and concrete cylinder pipe. This information will be used to provide a table of values for the quantity and type of anodes to be utilized for each pipe material. d. Submittals i Upon approval of the recommendations, ELK will prepare signed and sealed detail drawings. ELK will submit electronic copies of the drawings in digital exchange format (DXF), DGN, or DWG format. ii ELK will provide one set of D-sized, signed and sealed reproducible drawings to FW for bidding and one set for construction. iii ELK will provide a comprehensive cathodic protection specification including anodes, continuity bonding, electrical isolation, test stations, and acceptance testing procedures. B. Construction Support Services Proposal 08-1 108 Rev 2 09 December 2006 Replacement Contract WSM-1 Page 3 1 .
