Stairways made by Precast Concrete(PC) are emerging as alternative to traditional Reinforced Concrete(RC) stairways, PC stairs can reduce construction time and cost with improved quality compared to RC stairs. The existing PC stairway construction method often requires the placement of surrounding walls and PC stairways at the same time to secure connection between the two elements. The method described in this paper has the advantage of allowing the construction of walls and stairways in sequence, not together, this is possible because of developed technique for the connection and the other convenient ways for the PC stairways. Application of the method in various construction sites is analyzed and studied for further development.
