PROJECT QUESTION: The contractor is responsible for the design of the micropiles. A LRFD Factored Design Load has been provided, and is listed as a compression load. Do the micropiles also have to be designed to resist any lateral or moment loads?

Q: The contractor is responsible for the design of the micropiles. A LRFD Factored Design Load has been provided, and is listed as a compression load. Do the micropiles also have to be designed to resist any lateral or moment loads?

A: Design micropile and micropile connections to the structure for axial compression only. The axial compression value is listed as the Required Nominal Pile Bearing Resistance on Sheet BP8. Design for pile bending forces and/or lateral forces is not required. Note displacement limit in SB1-5.6.
