For friction piles depending on the friction resistance, accurate prediction of unit skin friction around the pile shaft is the dominant resistance to measure the final bearing capacity of a bored-pile. The present study measures the stress&#8722;strain transferring in two instrumented bored-piles (BP #1 &amp; BP# 2) embedded within the soil layer in Kuala Lumpur by real-time monitoring global strain extensometer (GSE) sensors. Two bored-piles (i.e., having 1.80 m and 1.0 m diameters, as well as 36 m and 32 m lengths) have been loaded with two times to their design working loads. Extensive data are analyzed to measure the changes in stress&#8722;strain in the bored-pile. The effect of loading and unloading stages on the pile&#8217;s head and base settlement has been monitored, indicating that Young modulus of elasticity in concrete bored-pile (<inline-formula> <math display="inline"> <semantics> <mrow> <msub> <mi>E</mi> <mi>c</mi> </msub> </mrow> </semantics> </math> </inline-formula>), average strain, and unit skin friction changed along the bored-pile based on the ground site conditions and stress registered. One example of two case studies with great real-time monitoring data has been provided to further design.
