Standardization of sub-structure design of subsidized housing in South Kalimantan

Abstract

The subsidized housing construction program is spread over two locations with two types of soil layers in South Kalimantan. Because of the difference in the composition and characteristics of the subsoil, the housing construction requires the standardization of design of sub/lower structure of the buildings namely for the deep foundations and shallow foundations which are used as typical subsidized housing foundations in South Kalimantan. This is necessary to ensure that the mass development of the subsidized housing construction meets the safety, time and cost requirements. The standardization of the structure of the lower building using a type of friction support with 4 m long galam wood piles for corner types and 4 section require 4 and 6 galam wood bars. The standardization of the structure of the lower structure on hard soil using a mountain stone foundation with a foundation width of 0.7 m and a foundation height of 0.7 m requires a foundation area of 1.40 - 3.50 square meter.
