This pile load testing comprised of one High strain dynamic pile load test carried out for working pile insitu concrete bored pile 1200mm diameter on the proposed interchange bridge at Changamwe interchange bridge Km 5+800

The test comprised the use of an impact device of a 7.3-ton hammer and using a PDA analyzer

The Pile Driving Analyzer was used with CAPWAP software for the analysis. The data selected for PDA and subsequent CAPWAP analysis on the piles was from maximum achieved load during driving and at the end of pile driving.

The working load for the pile is 3630 kN and testing was carried out to confirm load of 5445kN representing 150% of the working load. The tested piles were driven 34m in length from the ground level. The tests were carried out on 13th June 2019 using a Pile Driving Analyzer and associated equipment. The testing and dynamic pile field monitoring was carried out by Strainstall Middle East LLC and the test management was done by Asteriks Engineering Ltd. PILE INTEGRITY TEST Pile integrity tests was also carried out on the working piles for the Abutment 1 and pier 1 on the 15th June 2019 on 8 no piles
