- Engineer Benefits
- Improved efficiency: more time for engineering analysis and reporting, less time in transit or idle on location
- Can quote fixed costs per pile tested and analyzed
- Problem piles can be tested and addressed immediately
- No scheduling conflicts allowing for testing at multiple locations per day
- Support from experts available at time of testing either to do complete analysis and reporting or merely help with advice
- Less time away from home
- Safe work environment
- Contractor Benefits
- Scheduling conflicts are avoided; can test on the day and at the time of day that is most convenient to the project schedule
- Known cost to monitor a pile
- More options in selecting testing company, not limited to the local market
- Obtain results and recommendations sooner (analysis started immediately)
- Problems can be addressed immediately
- Can access knowledgeable testing engineers
- Owner Benefits
- Reduced testing costs
- Reduced factors of safety(LRFD) through additional testing at little additional cost
- More economical design through improved knowledge
- Less location variability risk because of more testing
- Accelerated construction
- Faster decisions
- No conflicts with test schedules
- Avoiding potential claims by addressing and documenting problem piles immediately
- Scheduling conflicts for testing are avoided; project stays on schedule
This practice is described in the following technical paper, which was co-authored by engineers, consultants and contractors who routinely perform PDA remote testing:
