Information on Piling work at construction project
Pile foundation is preferred in construction project when the safe bearing capacity of the soil / strata is very low and no other types of foundation can with stand their.

The attached document on piling works at construction project includes information on following topics;
What is a Pile?
Pile is a conduit through which load from the structure is transferred to soil either by friction or by bearing or by both.

Classifications of piles
Concrete Piles
- Bored cast in situ piles
- Driven cast in situ piles
- Driven Precast piles
Steel Piles

Test on piles
- Pile load test (vertical compression,lateral & pull out )
- Pile integrity test (low strain dynamic test)
- PDA test (high strain dynamic test)
- Lateral dynamic test
- Ultrasonic logging test
- “O” cell load test method.

Factors governing selection of types of piles to be used for construction
Practical consideration for selection of type of pile
Cost-Time Logistics and other factors aspect for selection of pile
Commercial consideration for selection of pile type

Members, I thought I would "Refresh" this thread and pass on some information that might be of interest to you, especially if you are new to piling or interested in learning some piling basics. I have written numerous articles on the subject of piling, including introductory information, how to assess piles being driven and some "Lessons Learned" articles where I've had to troubleshoot piling-related issues. Cheers!!!
