Sixty Percent (60%) Progress Submittal
The project drawings and specifications for each discipline are coordinated and directly moved to a 60%
level of design and will progress to the level where the design intent is established and must show the
work in sufficient detail that a contractor can recognize elements and requirements for construction. The
60% documents will also include the Draft PDR discussed under Task 2.
The ENGINEER shall finalize the process control narratives for the additional elements at the WRFs
along with all other design items, prior to completion of the 60% detailed design documents and after a

Drawings and details in all disciplines should be complete for all the additional design elements along
with the other design items. Specifications should be essentially complete. Design calculations in all
disciplines shall be essentially complete and checked. Comments on design, drawings and specifications
from previous reviews must have appropriate responses before the 90% progress submittal is submitted.
Comments from the 60 percent review by City staff, any constructability reviews, and review comments
from regulatory agencies must have appropriate responses or actions.
