Mike Cirba,
It's not ideal, it's simple, and practical.
And, it doesn't require the architect to camp out at the site.
Some, if not many contracts between the club and the architect call for a set number of visits within the context of the contract, with a proviso for additional visits for additional fees.
One of the purposes of the visits is for the architect to provide direction for the work to be done, and to approve or disapprove of the work in progress or completed to date.
If the architect feels that a particular feature has not been produced according to plan or direction, then the architect either accepts the alteration, or directs that it be modified to conform to his concept and directions, written or oral.
If the architect is working hand in glove with a representitive of the club, member or staff, then that decision is usually discussed with that party, and most likely that party will have discussions with others.
When a Member or Employee of the club is responsible for the supervision of the project, architectually, construction wise and financially, accepting the unauthorized alteration is not something routinely accepted, and there usually has to be strong valid reasons for the departure from the agreed upon work.
Supervision of the project is a major responsibility, and attention to detail usually insures that the club will get the intedended results.
A successful project usually doesn't happen by accident.
Competent work and supervision are key.
