Consequences of poor estimates, not uncommon:
- Cost over runs sometimes caused by poor estimates
- Even a stellar performance by engineering and construction could easily be overshadowed by budget over runs
- Risk of losing client for future jobs
- Poor prediction of required site man-hours could lead to setting unrealistic schedules
- Lack of confidence in the estimate could lead to arbitrary cuts in budget proposal
- Padding up with allowances hoping to cover uncertainty
- Large over runs in quantity
- Site man-hour overruns lead to bottle necks in site facilities
- Shortage of funding due to cost over runs lead to disruptions and consequent claims and delays
- Often times these have the effect of spiralling cost overruns much beyond reasonable limits
