Page 12 - The Consequences of an Incorrect Seismic Survey

When bedrock is shallower than known

1. Requires change in foundation system owing to unsuitability of an

originally specified system.

2. Increase in rock excavation volume for site development –

significant construction cost increase.

3. Loss of earth volume if need to fill up lower ground – have to

import fill at increased costs.

4. Incurs time and cost over-runs.

5. The only possible benefit – open up a crushed rock supply business!
