|Pile Testing||Bi Directional Static Load Testing|
We offer the Bi-directional Static Load Testing (BDLST) method for load testing of piles, which is a well-known static load testing method that uses a time and space saving approach of loading the pile resistance from the mid-pile or near-toe position instead of top-loading. Whether in a low headroom situation or within a cofferdam in the middle of a river, Bi-Directional Static Load Testing has risen to every challenge. Widely adopted in the US for bored piles, this static load testing method is gaining wide acceptance in many other countries for its many benefits and advantages.
The effectiveness and wealth of information yielded by Bi Directional Static Load Testing are the reasons why more engineers and contractors are turning to the method. Since the end-bearing and upward shear resistance are measured independently, there is no guesswork on how much load was carried by each component. Pile integrity testing is typically performed until the ultimate capacity in either shear or end-bearing is reached to determine the maximum pile capacity. The addition of strain gauges within the shaft can help to determine the distribution of the load throughout the shaft length. The speed and accuracy of testing have made Bi Directional Static Load Testing a valuable tool during value engineering and the redesign of projects.
