Robert Trent Jones was the first that I know that used the term signature in GCA, ref: "signature hole".
I think Jack may have been one of the first to start marketing the "Signature Course"
What you should know is that typically, adding “signature” to a design :
1. Does not change who does the actual designs of the course (in office or in field)
2. Usually escalates the fee by the GCA
3. Is typically a marketing ploy as earlier stated to sell homes, memberships,etc
4. Seldom changes the quality of the course in the end, since the owner controls the budget and sets the construction budget early.
5. will determine how many visits the Signature name appears on the site during construction and the opening.
Consider this, If YOU (as a GCA) were hired to design a golf course and you had just 2 different fees, A signature fee and a non signature fee, would you tell a client that a non signature fee course was not your BEST design effort? I would have a hard time telling my clients that they needed to pay me double just to get my best efforts.
I know one GCA firm who will tell you it is only about marketing, the GC will be the same. the additional fees by the GCA is appearance money depending how often they or members of their team show up.
