Top-down construction is a useful method of utilizing the working space, economic benefits and shorten the construction period. Precision construction of the elevator core is very important for safety of the top-down structure. In this study, the layout system for the field-BIM(Building Information Modeling) was used to precisely construct the elevator core in the basement and the ground. Through the layout system, it was possible to process the construction status, review the design results and construction errors, and confirm whether there is or not within the construction error range for elevator installation.

The main purpose of this study is the vertical circulation elements(stairs, elevator, ramp) in a Museum. The first is numerically analyzed in the study. And museum of Korea was limited to the case. The result of the study can be summarized as follows. 1. 50% of cases have 3~4 vertical circulation elements.; (1) ~8 elements: 1(3%), (2) 7 elements: 2(5%), (3) 6 elements: 5(13%), (4) 5 elements: 6(16%), (5) 4 elements: 8(21%), (6) 3 elements: 11(29%), (7) 2 elements: 4(11%), (8) 1 element: 1(3%). 2. There was "stairs alone", "elevator + stairs", "elevator + stairs + ramp", "stairs + ramp" in museum of Korea. Cases of "elevator alone", "ramp alone", elevator + ramp", "stairs + elevator + ramp" was not.; (1) stairs alone: 8(21%), (2) elevator + stairs: 21(55%), (3) elevator + stairs + ramp: 8(21%), (4) stairs + ramp: 1(3%).
