Long-term field monitoring dataset of foundation vertical deformation on medium-expansive soil

Over a monitoring period of 974 days, two critical parameters were recorded to evaluate the performance of the four foundations. The first parameter, vertical deformations, was measured using dial gauges. To ensure precision and accuracy, these measurements were validated with advanced instruments, including the line laser GLL 3-80 Professional and the LEICA DNA 10 digital levels. The second parameter involved the weekly cumulative rainfall, which was obtained from the General Directorate of Agriculture in Erbil, operating under the Ministry of Agriculture and Water Resources, Kurdistan Regional Government (KRG). This rainfall data was crucial for assessing the impact of environmental factors on the foundations over the study period.
The table summarizes the data collected over time for the deformations in the foundation and rainfall, clearly categorized into three data sets: Recorded Data - showing measured vertical deformation in millimeters for four foundation footings, Footing_1 to Footing_4, for particular dates. It shows that all the observed vertical deformations varied upward (+) over the period taken into consideration. The Vertical Deformation section shows incremental changes in the deformation with respect to the baseline date of 28 November 2021, and the footings show some variation. The data on the Weekly Cumulative Rainfall is in millimeters, and it can be seen that the fluctuations fall with periods of heavy precipitation, while at those instants in time the fluctuations of the footings deformation are quite great. These data combined show the ongoing interaction between environmental factors with the underlying deformation behavior of the foundations over time.
