  • Engineer Benefits
    • Improved efficiency: more time for engineering analysis and reporting, less time in transit or idle on site
    • 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 sites 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 site 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

The practice is described by four engineers (consultants and contractors) who routinely test using the remote PDA on the paper:
