“…The foundation is a very important job in a civil engineering job because it is this foundation that carries and holds a load that works on it, namely the top construction load (Magar et al, 2020). This foundation will channel the stresses that occur in the load of the superstructure into a hard soil layer that can bear the load of the construction (Pazha et al, 2019).…”

Purpose: Delays are common in construction projects. The term "project delay" refers to a project's completion date later than anticipated. Lack of performance by contractors or project managers in resolving issues can result in project delays. The factors that cause project delays must be considered to reduce delays. This study aims to examine the elements contributing to Batam island’s pile foundation construction delays. Findings: The factor of delays is an important key of the analysis to prevent delays in future projects Design/methodology/approach: This research uses a case study at Batam Island. The analysis is done with SPSS 26 program. Research limitations/implications: Analysis of delay caused by pile foundation in Batam island. Practical implications: Analysis of the delay caused by a project according to the result of the questionnaire. Originality/value: Original Paper Paper type: A Case Study

“…The reduced correlation caused by lower clay content was another reason the authors suggested that the SPT N-value was reliant on clay content. In addition, Pazha et al [17] developed the correlation of electrical resistivity and the SPT N-value using inversion modeling for subsurface hard layers. Alel et al [18] were successful in estimating the SPT N-value based on electrical resistivity data with acceptable accuracy using an artificial neural network (ANN) trained with particle swarm optimization (PSO).…”

Understanding the technical properties of the subsurface soil is essential for carrying out any building project correctly. In sandy soils in Phuket, Thailand, a correlation between electrical resistivity and the SPT N-value should be established in design to cut down on the time and expense of engineering field work for site investigation operations. Using the least squares method, the data of electrical resistivity and SPT N-values were fitted for regression analysis, and the behavior of the fitting coefficients was examined under various soil conditions found in the field. The factors affecting the link between electrical resistivity and the SPT N-value were found using data classifications of geology and climate. Phuket is located in a humid tropical region with frequent heavy rainstorms and extended periods of high temperatures and is composed of two main distinct geological areas: (1) igneous rock and (2) sedimentary and metamorphic rocks. According to the geological classification, the regression parameter (R2) of the relationship between the electrical resistivity and SPT N-values somewhat increased from a straightforward plot (R2 = 0.0171) to 0.1721, and the geology and climate data categorization revealed the best fit which is an exponential model (R2 = 0.6175). By re-examining the two VES lines under the identical bedrock and climate characteristics as the original model, the relative R2 of 0.5519 validates the association between electrical resistivity and SPT N-values. It is important to emphasize that the geology and climate of the collected data have an impact on the correlation model. Furthermore, a geotechnical investigation should be used to confirm the findings of an electrical resistivity survey as a preliminary tool to assess any problematic subsurface zones. However, more field test data from diverse places must be acquired in order to establish the relationship between the SPT N-value and electrical resistivity of sandy soils.
