During the construction of underground space expansion of old facilities, it is necessary to secure temporary residence space for existing residents as well as noise and vibration issues during construction, and in the case of commercial, industrial, and social use, damage is expected from suspension of the use of facilities. There is a need for a technology that minimizes noise and vibration during underground expansion, enabling the use of existing facilities even during construction. In this study, a practical underground extension model is proposed by analyzing the behavior of the temporary structure and the surrounding ground as a result of measurement at each construction stage for a actual construction site. In order to solve the problems that occurred during construction, the basement slabs were placed in advance after the initial excavation. The measurement results (building inclinometer, crack measurement system, structure inclinometer and surface settlement meter) at the site were reviewed to analyze the behavior of the temporary structure and surrounding ground. As a result, it was confirmed that the inclinometer of the building and the structural inclinometer showed a tendency that the displacement after the slab line was placed was reduced or converged. The placement of basement slabs during underground extension not only relived the noise and vibration problems during construction, but also secured the stability of structures.

The Vocational Rehabilitation Center Expansion Project, with a budget of 15.3 billion KRW, transformed an existing facility into a more eco-friendly, user-friendly, and publicly accessible space. The project involved expanding the building from a basement and two above-ground floors to a basement and six above-ground floors, addressing the shortage of facilities for people with disabilities while promoting eco-friendliness. Design concepts included eco-friendly MASS, improvements to the existing building, social adaptability, and user-centric evacuation measures. Value Engineering (VE) and technical reviews led to proposals for cost reduction and functionality enhancement. Completed in September 2019, the project, renamed "Se-um Center," now hosts seven disability welfare facilities, serving as a vital infrastructure improving the lives of individuals with disabilities in the local community.
