ThisThis extra work during construction can be avoided if the design review process extra work during construction can be avoided if the design review process could be improved. Also, A Possible solution to this is to have a dedicated staff could be improved. Also, A Possible solution to this is to have a dedicated staff of people from these departments to form a team specifically to do the design of people from these departments to form a team specifically to do the design reviews Also, when the proponent and support departments review the 60% reviews Also, when the proponent and support departments review the 60% detail design, they come up with major scope changes, which will have a cost detail design, they come up with major scope changes, which will have a cost and schedule impact.
