O&M Needs Indicated and provided by manufacturer.<br />
Repair Requirements<br />
<strong>for</strong> Rehabilitated<br />
Sections<br />
Periodic visual inspections every two years would be ideal.<br />
Top coat renewal feasible if abrasive environment.<br />
Any debonded composite to be removed and new laminate applied.<br />
V. Costs<br />
Key Cost Factors Exact pricing will depend on:<br />
1) Distance from repair location to surface access.<br />
2) Quantity <strong>of</strong> lineal feet contracted<br />
3) Lead time <strong>for</strong> crews mobilization<br />
4) Allotted time <strong>for</strong> onsite completion <strong>of</strong> project<br />
5) Project service life <strong>of</strong> repair<br />
Case Study Costs The cost <strong>for</strong> the carbon fiber application is about $75 to $90 per layer and per feet 2<br />
<strong>of</strong> surface area. Typically, a 54 inches pipe operating at 150 psi with 12 feet <strong>of</strong><br />
cover would be $3,000/feet.<br />
