I work for a small Water District and we are expanding our treatment plant, adding 4 new filters, upgrading pre-treatment as well as building new admin building and laboratories ($11 Million dollars is budgeted). We are trying to find some references that verify what a reasonable consulting engineering fee is for each of these two phases;
Phase 1 – 60% Design and Contractor selection
Does anyone have any industry documents (ASCE, APWA, AWWA, or other..) that we can reference for typical percentages we should expect to pay?
Thank you in advance!
