Building construction method

Abstract

A building construction method includes the steps of forming pile holes, installing piles, installing pile connecting beams, forming a concrete ground floor structure, erecting a building framework, forming walls on the building framework, and forming floors on the building framework. The construction method facilitates the construction of low-rise buildings at a relatively low cost.
