The School of Mines, later to develop into the School of Engineering and Applied Science, consisted at this time of one room in the basement of a Madison Avenue academic building. Within the first year of the School's existence, Chandler took on the position of Dean, and under his leadership in that first year the school moved to a larger four floor building and doubled the number of students enrolled in its program of study. Chandler was to remain dean of the School of Mines for the next 33 years, through its move to its new home on Columbia's Morningside Campus and into Havemeyer Hall, the state-of-the-art Chemistry building that he helped to design and raise funds.
