1-10: Constructability Review

Practice Statement: Although constructability reviews should occur
throughout the design stage, prior to the finalization of the design, the
project should be subjected to a constructability review. The participants
in this process should include a constructor, the project designer/engineer,
and the project owner. Other participants could include the owners affected
by the project. This process should result in a final design which can be
circulated as appropriate for approvals.

Practice Description: This practice will allow the designer/engineer,
constructor, project owner, and facility owners to assess the constructability
of the project design, assess project alternatives, review proposed schedules,
and to facilitate smoother, less costly, more efficient and safer construction.
Benefits: The application of constructability reviews will result in more
efficient construction, more effective design, reduced costs, and improved
safety.

1-11: Use of Qualified Contractors

Practice Statement: Qualified contractors should be used to excavate on
and near underground facilities.
Practice Description: Contractors that excavate on and near underground
facilities should possess the qualifications necessary to conduct such
activities in a manner that is both safe and reliable, and ensures a quality
product. The use of qualified contractors ensures that contractors retained to
work on a project are capable of performing the work required, and operate
safely. By requiring contractors to be qualified, public safety is protected as
is the integrity of the underground facilities in the area of the excavation.
Allowing a competitive bidding process from qualified, competent, and
experienced contractors should assure both quality and price, and should
minimize the risk of damage to underground facilities.

Example of Practice: Most large organizations involved in capital works
have developed policies to qualify contractors. These policies often involve
establishing criteria in such areas as financing, insurance, occupational
