Example text

In northern climates, the construction season may be limited to only five or six months of the year due to weather constraints. For large projects, the work may need to be scheduled over more than one year. Getting approval to draw down reservoirs is often difficult. If approval is given, it is generally only for a very limited period of time to minimize any impact on recreation, fish and wildlife, and water supply. Staging and scheduling the work in areas requiring a draw down can be critical if a large amount of work is to be done in a short period of time.

Hydrology assessment. Spillway adequacy. Stability assessments of water-retaining structures. Status of studies in process and outstanding issues. References. Each licensee is required to maintain the STID current. In the context of extending the service life, or improving the performance of a project's civil works, the STID can be a rich source of useful information. Project Personnel Knowledge The above discussion centers on paper or electronic records - calculations, test results, drawings, photographs, reports, and the like.

Later, after the preferred alternative is identified and final design is complete, an estimate should be done to determine the cost of the project. The estimate will be used for internal budget and to help evaluate the contractors' bids as they may vary significantly. The estimate will help determine if the contractors have understood the scope of the work, or if further clarifications are required. Site-specific parameters need to be taken into consideration in the cost estimate for a project.
