Capital CostCapital cost is the primary consideration for most construction projects. However, designers and contractors often fail to account for all the costs relating to a pipeline installation by focusing only on the cost of the pipe. This can lead to missed opportunities; significant installed cost savings can be made by properly addressing the structural design of the installation.
Pipelines of different materials can be considered structurally as rigid or flexible systems. Concrete is a rigid system and as such, the strength and structure of the pipeline comes mainly from the pipe itself, achieved in a controlled factory environment. In contrast, a flexible pipe acts only as a conduit and the construction of the supporting structure takes place on site where the integrity of the system is heavily reliant on the design and quality of the installation.
There are a number of alternative bedding design options for concrete pipes and unlike flexible systems, a full granular surround is not always required. This can result in a number of cost advantages:
- Excavated material can be re-used as backfill.
- Less imported granular material required.
- Time saved during the infill and compaction cycle.
- Reduced disposal of waste to landfill.
