The Contractor must have as part of his design team a licensed structural engineer per Host Nations standards. If work is being performed in a country that does not have licensed structural engineers, then engineering degrees along with extensive structural design experience can be submitted to the KO for qualification verification and approval. The structural engineer’s licensure or qualifications must be submitted to the KO in the design quality control plan prior to the start of design. The Contractor’s structural engineer must be responsible for the design of any part of the building structural systems.

The structural design of the foundation, superstructure and any other structural aspects must be in accordance with the design criteria listed in this document.
