1.3.6.1
Coatings
Coatings for metallic components shall be as required for metallic
fittings. Protective covering (coating and taping) shall be completed and
tested on each metallic component and shall be as required for underground
metallic pipe.
1.3.6.2
Tracer Wire
When a nonmetallic pipe line is used to extend or add to an existing
metallic line, an insulated No. 8 AWG copper wire shall be connected to a
terminal in a test station located at each point of transition from
metallic pipe to nonmetallic pipe. At each of these test stations, the
tracer wire terminal shall be strapped or bonded to the terminal for the
negative connection wire to the existing metallic line. The tracer wire
shall be run the length of the new nonmetallic line. This wire shall be
used as a locator tracer wire and to maintain continuity to any future
extension of the pipe line.
1.3.7
Services of "Corrosion Expert"
The Contractor shall obtain the services of a "corrosion expert" to
supervise, inspect, and test the installation and performance of the
cathodic protection system. "Corrosion expert" refers to a person, who, by
reason of thorough knowledge of the physical sciences and the principles of
engineering and mathematics, acquired by professional education and related
practical experience, is qualified to engage in the practice of corrosion
control of buried metallic piping and tank systems. Such a person must be
accredited or certified by the National Association of Corrosion Engineers
(NACE) as a NACE Accredited Corrosion Specialist or a NACE certified
Cathodic Protection (CP) Specialist or be a registered professional
engineer who has certification or licensing that includes education and
experience in corrosion control of buried or submerged metallic piping and
tank systems, if such certification or licensing includes 5 years
experience in corrosion control on underground metallic surfaces of the
type under this contract. The "corrosion expert" shall make at least 3
visits to the project site. The first of these visits shall include
obtaining soil resistivity data, acknowledging the type of pipeline
coatings to be used and reporting to the Contractor the type of cathodic
protection required. Once the submittals are approved and the materials
delivered, the "corrosion expert" shall revisit the site to ensure the
Contractor understands installation practices and laying out the
components. The third visit shall involve testing the installed cathodic
protection systems and training applicable personnel on proper maintenance
techniques. The "corrosion expert" shall supervise installation and
testing of all cathodic protection.
1.3.8
Spare Parts
The Contractor shall submit spare parts data for each different item of
material and equipment specified, after approval of detail drawings and not
later than [_____] months prior to the date of beneficial occupancy. The
data shall include a complete list of parts, special tools, and supplies,
with current unit prices and source of supply. One spare anode of each
type shall be furnished.
