The purpose of this study is to suggest the rational plans of Information Management in the interior finishing work. The results of this study are summarized as follows; I) Analytical survey of actual construction progress of interior finishing work 2) Review of computer-based development in construction planning & information management of interior finishing work 3) Structure of interior finishing work Planning and Management Support System And the expectancies of this paper are that it can be used as efficient data for improvement of system to systematize planning and execution of interior finishing work in korea.

Despite the importance and function of productivity information, in the Korean construction industry, the method of collecting and analyzing productivity data has not been organized. Also, in most cases, productivity management is reliant on the experience and intuitions of field managers, and productivity data are rarely being utilized in planning and management. Accordingly, this study intends to develop a prediction model for interior finishes of apartment using deep learning techniques, so as to provide a foundation for analyzing the productivity impacting factors and predicting productivity. The result of the study, productivity prediction model for interior finishes of apartment using deep learning techniques, can be a basic module of apartment project management system by applying deep learning to reliable productivity data and developing as data is accumulated in the future. It can also be used in project engineering processes such as estimating work, calculating work days for process planning, and calculating input labor based on productivity data from similar projects in the past. Further, when productivity diverging from predicted productivity is discovered during construction, it is expected that it will be possible to analyze the cause(s) thereof and implement prompt response and preventive measures.

Experiments of Cone calorimeter test and Lift spread flame apparatus test are carried out in order to appraise fire hazard in color nonwoven used mostly on the spot in construction works. As the result, in color nonwoven combustibility is discovered not firing flame in surface, but firing under state of combustible gas occuring in the state of melting. In the case of Lift spread flame apparatus test, color nonwoven is very brittle which almost no flame spread owing to contracting and break by firing strength. The following data are agree with basis: total heat release is 2.66 MJ/$m^2$, limited combustible material (10 min) of incombustible rating appraisal in interior material of building, and incombustible materials (5 min) 8 MJ/$m^2$ in spite of the above data mentioned, those data are only as basis of interior finish, and so I cannot judge color nonwoven have incombustible rating retain through the above data. Accordingly, the basis of incombustible rating and experiment method about exterior finish must be arranged also.
