removal, and repair of new products or installations that are not defined within
another recognized classification. (
2.
Why does CSLB restrict D-64 work to activities outside already recognized
contractor classifications?

classifications.
C. To allow D-64 contractors to perform unlimited general engineering work.
D. To require every contractor to obtain multiple classifications simultaneously.
Answer: B
Rationale: D-64 is a residual classification for qualifying work that does not fit an
existing classification; it is not intended to bypass established classification
boundaries. (web.cslb.ca.gov)

A contractor proposes work clearly covered by an existing specialty
classification rather than D-64; what should happen?

under D-64 or another classification?
