8.0 RISK ASSESSMENT
Schedule Risk Mitigation
Design and Preconstruction Phase
As utility owners do not have the same contractual obligations to the
Village as the design team, it is particularly important to develop methods
to mitigate the risk they present to the overall project schedule. To mitigate
this risk, it is recommended the Village initiate design of multiple, separate
work areas at one time and overlap phase schedules so the impact of
a delay in the design of a single phase on the overall project schedule is
reduced. By having multiple phases with multiple work areas per phase,
the portion of the Village in active construction at any given time is small
relative to the project size, therefore reducing the perceived impact to the
community at any given time while providing schedule control benefits
to the Village. By overlapping the phases, the utilities can design future
phases while construction work is active in a previous phase. This provides
additional time not only to complete the design work, but to identify
and procure equipment easements. This reduces the risk to the overall
project schedule if the design of any single phase is delayed due to storm
recovery efforts.
Certain significant pieces of equipment required for completion of the
project have limited flexibility where they can be located in the final design
of the underground system. An example would be a switch cabinet that
marks the limit of a service area boundary defined by electrical load
demand. Since these pieces of equipment must be located in certain
areas, a longer duration to acquire the easement may be necessary if
property owner negotiations or an eminent domain process are needed.
Identifying these locations early in the planning and design process
provides extended periods of time to acquire required easements prior to
each project area going into construction.
potential bidders and allows for lump sum bidding for various scopes of
work. Lump sum bidding can be employed on infrastructure projects when
the scope of work is clearly defined and the risk of quantity overruns is low.
Unit price bidding is traditionally used on projects where quantities are likely
to change because precise estimates cannot be made.
Construction Phase
To mitigate the risk the chosen contractor fails to perform the work within
the desired schedule, we recommend:
 requiring bidders submit historical evidence with their bid proposal
to demonstrate past success in meeting schedules on similar
projects
 requiring bidders submit references with their bid proposal the
Village can contact to discuss schedule performance on past
similar projects
 engaging a Construction Manager who has the authority to remove
and replace poor performing subcontractors and/or to bring in
additional resources when threats to the project schedule are
identified.
To mitigate the risk of unforeseen subsurface conditions impacting
construction and to properly plan for the installation of the electric and
communications infrastructure, we recommend record drawing research
and soft dig utility locates be performed for known and identifiable utilities
during the design phase. As a result, the risk of underground utility conflicts
leading to schedule delays and construction claims is reduced. This also
increases the clarity of the construction documents, which reduces risk to
