Key Construction Risks from Systems Outside the Boundary Wall of the Plant

Generally all systems outside the boundary wall of a thermal power plant carries a huge construction risk.

These systems include:
1. Cross Country Pipeline for delivering the water to the thermal power plant
2. Transmission Line  for delivering the electricity produced at the plant to the nearest point in the grid
3. Railway Siding for delivering coal to the power plant

Generally the amount of risk is directly proportional to the length of system. For instance, a cross country pipeline of 60kms carries a much bigger risk than a cross country pipeline of 20 kms.
 
Generally for Cross Country Pipeline and Transmission Line, we only need to get Right of Way (ROW) which is sort of lease model and need not actually acquire the land. However for Railway Siding, we have to actually purchase the land. Land acquisition is a long and cumbersome process as there maybe more than 2000 individual land owners for a railway track of 20 km length.

For Cross Country Pipeline, its a better strategy is run your cross country pipelines  parallel to the road or a national highway and offset it from the highway by 10 to 30 metres. Generally the land around the highways is owned by Highway Authority or other Government bodies and getting the ROW is much simpler. However, as there maybe plans to make the highway from 2 lanes to a 4 lane highway in a few years and you maybe asked to relocate your pipeline. The plant owner must protect himself against this by leaving sufficient distance from the edge of the road or highway.

Additionally our pipeline may also be crossing local roads, national highways, rivers, canals, railway lines, other pipelines, petroleum pipelines etc. While finalizing the route of the cross country pipeline we must have a very clear strategy for overcoming all these challenges.

What is BIM and 3D, 4D and 5D ?

Building Information Modeling is the process of converting the 2D drawings into a 3D model on the computer. The structural, architectural and mep drawings are used as inputs to create an very accurate 3D model.

Archicad and Revit are the most popular softwares used for BIM modeling.

This model can be used for:

1. For spatial visualization of the building

2. For doing constructiblity analysis
eg if the slab level shown in architecural drawings and structural drawings are different or if a pipe if going through a lift shaft, then BIM would be able to identify that.

3. For generating sections from anywhere in the building. Time is saved as the BIM software does this automatically.

4. Preparing Bill of Quantities from the BIM model is fast. Take-off sheets can also be prepared. This is infact called the 4D or the cost.

5. The items in the Bill of Quantities can be exported to a scheduling software such as Primavera, MS Project or Vico Control to sequence the construction activities. The tasks have location data and quantity data already built into them, so scheduling is faster and more accurate. This is called 5D.

6. Future add-ons to BIM sofware would include structural analysis, energy analysis for calculating tonnage of air-conditioning required, preparing BBS for pre-fabrication, etc.

I have used BIM softwares on a few project and feel that a big change is underway in the construction industry.
