Abstract

Currently, the world is facing Global Warning Phenomena, El Nino and La Nina, each of these natural phenomena makes above-average rainfall at a time and place and an area, especially impacting large cities that are passed through by water due to high rainfall. With inadequate city channels to accommodate rainwater flow, it results in, among other things, high floods, landslides due to the soil no longer being able to accommodate high rainfall, high Rob floods due to seawater overflowing into coastal areas of the city. Based on the disaster data due to high rainfall, Research, Handling and Mitigation Planning is needed with the aim of obtaining data for drainage design. The study is the observation of rainfall for 2 years, 5 years, 10 years, and 20 years, so that by calculating the intensity of rain using the Gumbel and Pearson III Log distribution methods, accurate data is obtained to determine the drainage dimensions that must be made in a city and the dimensions of retaining walls along the coast to overcome storm disasters in coastal areas or big cities.

Abstract

The substructure of bored pile foundations is one type of deep foundation commonly used in high-rise building construction, particularly in areas with low soil bearing capacity, such as the ARC 100 Gubeng Construction Project in Surabaya. Both primary and secondary data were collected through interviews with contractors and project service providers involved in the foundation work. Based on the observations conducted, the bored pile foundation work utilized the wet boring method using Zoomlion heavy equipment, beginning with the preparation stage, determination of foundation bore points, and site cleaning. This was followed by the installation of temporary casing, foundation hole drilling, reinforcement fabrication, reinforcement placement, and welding of reinforcement joints. Next, a slump test was performed on the concrete mix, followed by the installation of the tremie pipe, concrete casting, removal of the temporary casing, and final site cleaning. The bored pile foundation work for the ARC 100 Gubeng project in Surabaya was carried out in accordance with standard construction procedures. Any factors that could potentially hinder the work were promptly addressed. Furthermore, both the contractor and consultant agreed that workplace safety must always remain a top priority throughout the entire construction process.
