“…The study revealed that the site was suitable for construction of bored piles as enclosure structure. It also recommended application of steel bracing material enhanced with a hydraulic servo system as basement the basement soil excavation process can cause uneven ground surface settlement, cracks, and structural deformation on the adjacent structure (Guo et al 2019;Pawirodikromo 2022). To achieve a smooth deep basement construction process in complex urban environments, the site survey engineering analysis is necessary before the basement construction process (Benin et al 2016).…”

Deep basement construction is characterised by a deformation challenge for the excavation pit and adjacent structures. Basement construction is an unavoidable problem in urban areas. A case is found in a Triumph Unit building block project, where a 14 m basement will be constructed near the existing structures. Conducting a site survey engineering analysis before the deep basement excavation is essential to guarantee safety during basement construction. Site survey engineering analysis is vital in recommending a suitable support structure for the basement pit during excavation. Therefore, this paper takes the Triumph Unit high-rise building basement excavation project as a practical application of site survey engineering analysis on the actual construction site. Geotechnical and groundwater characterisation were achieved through field and laboratory tests. The study revealed that the site was suitable for construction of bored piles as enclosure structure. It also recommended application of steel bracing material enhanced with a hydraulic servo system as basement excavation internal support structure. The recommended support structure is applied to the actual excavation. The excavation-induced deformation with respect to the recommended support structure application is strictly monitored and controlled. The measured project site results show the effectiveness of site survey engineering analysis in recommending a suitable deep basement excavation support system that controls the excavation-induced deformation desirably.

“…Earthquake shocks can cause great damage to building structures resulting in many casualties [4]. Structural damages are related with the level of seismic intensity, low material quality and so on [5], [6]. To reduce damages in building structures, the Indonesian government has updated the seismic resistant design code for building and non-building structures in SNI 1726-2019 [7] In 2012, the Indonesian government has issued a seismic design code for building and non-building structures in SNI 03-1726-2012 [8].…”

Aceh is one of the most earthquake-prone regions in Indonesia. It is, therefore, essential to design seismic resistance structures according to applicable standards. To reduce damage to building structures, the Indonesian government has updated the seismic-resistant design code for building and non-building structures. The seismic resistant design standard has been updated from SNI 03-1726-2012 to SNI 03-1726-2019 due to a significant change in spectrum response data. The purpose of this study was to evaluate and compare the impacts on the seismic base shear and the cross-sectional area of columns, beams, and tie beams of buildings in 23 regencies in Aceh Province based on SNI 03-1726-2012 and SNI 03-1726-2019. A typical five-story office building with medium-type soil is used in the study. For structural analysis, a particular moment-resistant frame was considered. The determination of the design response spectra is carried out by using coordinates and soil types through the website “indo spectra”. The method used is spectrum response analysis. Some different requirements in the two standards include the spectrum response curve, mass participation, and dynamic base shear. The study’s results revealed that the dynamic base shear in Sabang City had grown by 192.05 percent. Aceh Barat Daya Regency was observed to have the smallest increase in dynamic base shear, which was only 8.16 percent. The required cross-sectional area of structural columns, beams, and tie beams in Sabang City increased by 96%, 40%, and 44.44%, respectively; in the meantime, the required cross-sectional area of columns, beams, and tie beams in several regencies in Aceh province remained unchanged.

Indonesia is located in one of the most seismically active regions in the world and often experiences damaging earthquakes. In the past the housing sector has sustained higher earthquake related damage and losses than other sectors. This is often attributed to the fact that the most common houses in Indonesia are non-engineered, built with poor quality workmanship, poor quality materials and without resilient seismic design features. However little effort has been made to quantify how fragile Indonesian houses are, or how their fragility may vary according to the population density or relative wealth of a region. It is not possible to derive empirical fragility functions for Indonesia due to insufficient damage data. The aim of this study is to determine whether existing earthquake fragility functions can be applied to common house types in Indonesia. Scenario damage analyses simulating the 2006 Yogyakarta and 2009 Padang events were undertaken several times testing different fragility functions. The simulated damage results were then compared to the damage observed post event to determine whether an accurate damage prediction could be achieved. It was found that the common house types in Yogyakarta and Central Java vary according to age of construction, location and relative wealth of a region and can be reasonably well represented by existing fragility functions. However, the houses in Padang and surrounding West Sumatra did not vary in a predictable manner and are more fragile than anticipated. Therefore, the fragility of the most common house types in Indonesia differs between Central Java and West Sumatra. This has important implications for seismic damage and risk assessment undertaken in Indonesia.
