Urkkada is a recognized expert in the field of pile testing. Our staff have been on high profile, complex projects in many all types of environments. From future skyscrapers in downtown Manhattan, to bridges in the rocky mountains of Alberta, to the jungles of the Caribbean.
Wave Equation Analysis – WEAP
Wave equation analysis are performed prior to pile driving to assess the drivability of the desired pile, accounting for the hammer type, hammer energy, and the site soil conditions. A WEAP can ensure that piles are driven in the most efficient manner, while reducing the danger of pile damage.
High Strain Testing – PDA and CAPWAP
Dynamic testing of piles using the PDA methodology is one of the best ways to determine pile capacity. It allows for the rapid testing of piles in a production environment, minimizing slow downs to the driving program. PDA data can be further analyzed using CAPWAP to simulate a static load test on the piles.
Low Strain and Cross Hole Logging
Low strain testing such as PIT is an excellent method for testing cast-in-place piles and caissons. This technique can identify necking, fractures, and other potential points of weakness.
Cross hole sonic logging is a testing method used on critical concrete caissons. An array of cast-in-place tubes are tested by simultaneously raising probes on adjacent tubes. The cross hole system will map the concrete between the tubes, and when combined with multiple passes, a detailed image of the concrete is created. This insures that critical components are as intended, ready to perform for many years.
