* This technique could potentially produce durable concrete piles for coastal regions
 that will address the problem of corrosion because carbon unlike steel does not
 corrode.

* Cover concrete to the CFRP grid tubes should be kept to a minimum to minimize the
 loss of capacity to the piles when the unconfined cover concrete crushes.

* Prestessing of the carbon reinforcing bars is recommended. Prestressing can reduce
 displacements and also help keep the bars at the correct locations during the spinning
 process.

* The use of internal carbon stirrups as shear reinforcement is recommended. Because
 the concrete cross-section is reduced due to crushing the carbon shear reinforcement
 should be designed to resist all of the expected shear forces. This is a conservative
 approach. Alternatively, only a portion of the concrete cross-section (for example
 50%) can be considered for shear resistance.
