Precautions For Bored Piles Construction And Inspection There are several precautions that need to be considered while inspection and construction of bored pile foundation is preceded these precautions will be discussed in the following sections fig1 bored pile construction precautions for bored piles construction and inspection if the pile is built in water bearing soil then it is required to provide casing Acceptance Criteria For Bored Piles By Ultrasonic testing or crosshole logging csl is now a widespread means for evaluating the integrity of bored piles in many specifications anomalies observed in the ultrasonic test results are a sufficient reason to reject a pile nevertheless the definition of what constitutes an Tests Of Bored And Driven Piles In Cretaceous Mudstone At Crossjacking tests in the pile sockets and crushing tests on mudstone cubes correlated well with the pile test results indicating an ultimate end bearing capacity of nine times the undrained shear strength and an average shaft adhesion factor 02 unconfined compression tests on cylindrical core specimens appeared to underestimate and Pile Foundations Design Construction And Testing Guide In this background if look at the available options we have to select the type of foundation from bored piles precast piles and micro piles out of those bored piles are more costly in general when compared with the other two types depending on the nature and the type of loads from the superstructure the selection of the piling type is made Deep Foundation Testing Products From Pile Dynamics High strain dynamic load testing for drilled shafts and bored piles top force transducer swift economical accurate high strain dynamic load testing for drilled shafts and bored piles learn more accurate proven reliable provides quick and accurate monitoring of force and displacement during a static load test
