Aba Al-Aitam Dormitory Office Building, Pacitan is a reinforced concrete structure that has been re-design using a special moment frame system. Because the location of the building is in the earthquake zone D, it is required to use a special moment resisting frame system to be used as a seismic lateral force resisting system based on SNI 1726: 2019, and for designed reinforced concrete structures based on SNI 2847:2019. This redesign begins by analyzing the existing structure from technical drawings and data to select the type of seismic load analysis method using the static equivalent method. Then calculate the basic loads (gravity load and seismic load) and combination loads which will be used to analyze the structure using the STAAD Pro program. Based on the analysis that has been done, the result floor slabs is 120 mm, roof slab is 100 mm, dimensions of primary beams 1 & 3 are 250/350 mm, dimensions of primary beams 2 & 4 are 300/600 mm, dimensions of secondary beams are 250/300 mm, dimensions of cantilever beam 1 are 250/300 mm, dimensions of cantilever beam 2 are 300/600 mm, and column dimensions are 600/800 mm. With the condition of the deviation between floors due to gravity loads and earthquake loads (Story Drift) that have been controlled safely
