Appropriate sequencing of tasks is a vital part of the planning process. The tasks must be sequenced logically and efficiently.
The overall sequence of works is generally:
- site clearance
- foundation construction
trenches and ducts
- Substation construction,
- mounting frame
- electrical site works
grid works and then testing and commissioning.
Each of these work areas should be broken down into a series of sub-tasks. Alongside, an assessment of the inputs required for each task (especially when interfaces are involved) will help develop a logical and efficient sequence. Consideration should also be given to any factors that could prevent or limit possible overlap of tasks.
These factors could include:
• Access requirements.
• Resource availability (plant and manpower).
• Planning (or other regulatory) restrictions.
• Safety considerations.
