Design-Build Project Schedule Development and Management - Design-Build for Water and Wastewater Projects - page 245

With DB, the baseline schedule, and subsequently the operational updated schedule,
is easily aligned with the owner's goals and objectives. All delaying events typically asso-
ciated with the design are no longer beyond the control of the design-builder, and this
significantly reduces the number of claims requesting additional time.
Four tangible scheduling best practices are offered herein for DB water and waste-
water projects:
1. Integrate the CBS with the WBS to develop tasks to be included in the schedule.
This integration naturally lends itself to the use of the earned value methodology
for project control.
2. Perform periodic updates of the project schedule using the units-in-place meth-
odology. An additional by-product of this practice is the contemporaneous cre-
ation of the as-built schedule.
3. Adopt a contemporaneous “live or die” thought process while measuring the
impact of delaying events on the project.
4. Two unique aspects of water and wastewater projects are permitting and com-
missioning. Activities associated with permitting and commissioning can have
a significant impact on the project's schedule. When in the planning process of
schedule development, it is recommended to consider a variety of scenarios for
permit and commissioning outcomes.
