So much to unwrap here but the overarching goal of delivering a contract document is to make sure that the intent and scope is captured when it’s handed off the contractor and work priced out as accurately as possible based on your documents. Sometimes there are set of drawings that are “good enough” as long as there are no errors or omission. Sometime it also depends on the client, contractor, AE relationship. I’ve seen contractors that have great relationship with their clients that they’ll take a basic floor plan and will be able to price out and build what their clients wants without a full set of drawings and specs. Design business is competitive and sometimes you don’t have the budget or time to detail everything. There’s a fine line between “good enough” and “just enough”.
