NDT were asked to undertake the preliminary pile load testing for Central Piling, the company awarded the contract to install a contiguous wall (295 linear metres of 600mm diameter) on the high-profile project. John explains that this presented the “perfect showcase for NDT Services to deploy one of the Titan pile testing systems the company now operate”, which can complete fully-automated and unmanned static load testing and demonstrate many advantages for the client.
One advantage of the system is the instantaneous data feedback that enabled the test results to be analysed and closely monitored in real time: “NDT and Central Piling demonstrated a test scenario where instantaneous live feedback could be analysed and discussed at an early stage. The resultant conclusions allowed potentially anomalous data to be discounted and the test to continue after necessary adjustments were carried out.”
“The precise loading control, ability to amend target loads mid-test and the advanced remote monitoring facility were seen as essential to achieving the demanding test criteria,” says John. “In addition to the technical advantages, the safety benefits included removing test operatives from a potentially high-risk environment,” which was, John remarked, particularly important to the client.
NDT now offer this level of data access on all static preliminary and working load test piles positioning the company at the forefront of pile testing technology.
