 Construction of Stabilization Works
Concepts of construction will be discussed under these headings:
Coordination of design and construction;
Specialized contract provisions;
Environmental protection;
Specialized construction procedures; and
Site preparation and restoration.
10.1 COORDINATION OF DESIGN AND CONSTRUCTION
The designer should encourage communication with, and develop a rapport with,
construction personnel by being supportive and cooperative when problems or disagreements
occur. Communication should begin as early as possible in the planning and design stages.
Ideally, the concept of the proposed work would be discussed with construction and
operations personnel, followed by a review of plans and specifications prior to finalization.
The formality of these actions can vary, but it is good practice to document the results in
order to prevent future misunderstandings.
The designer should visit the job site occasionally when the work is going well, and
frequently when it is not, not to infer a lack of trust in construction personnel, but simply to
demonstrate an understanding of the importance of competent construction. These visits also
familiarize the designer with construction practices, as well as informing construction
personnel of the factors which went into the design of the work. They can then better
distinguish between those changes in site conditions which are significant and those which are
not. At the same time, construction personnel should be encouraged to notify the designer
of significant site changes.
10.2 SPECIALIZED CONTRACT PROVISIONS
The following areas offer opportunities for insuring that contract provisions provide
a framework for quality workmanship, fair and efficient contract administration, and a
maintainable project:
Specifications and bid items;
Restrictions imposed by river conditions;
Preconstruction verification of design ;
Stone gradation and quality;
Specifications for commercial products; and
Documentation of as-built condition.
Specifications should also clearly address environmental aspects of the work, as
discussed in 10.3.
