The Monadnock building was completed by John Root, a designer of the famous Burnham & Root Company, from 1891 to 1893. At the beginning, the building consisted of 16 storeys, the highest of which was the tallest and the heaviest building, with the basement level being six feet thick.
As a result, the ground floor of the building looks like a very dark ground, and as the floor increases, the thickness of the walls becomes thinner. Therefore, as the Monadnock Building rises, the rooms become larger, and the walls on the top floor are still 18 inches thick.
In fact, because of the Chicago area, it’s a very wet and humid region, with buildings like Monadnock built of bricks.
A reporter for the New York Times described Chicago’s soil as a giant “semi-fluid,” with cacao. To prevent the building from deteriorating in the soil, the engineers worked to build a railroad-like concrete structure at the bottom of the building and to maintain the weight of the building.
The steel frame was 11 feet longer than the Monadnock building, and when the structure was completed, the monadnock was submerged about two feet below the ground.
Engineers originally estimated that Monadnock would drop to 8 inches below ground level, but the relative humidity of the silicon soil was astonishing. As a result, the ground floor of the Monadnock Building has fallen from the street level.
In fact, Monadnock’s existence is due to the skillful engineering of John Root. John was not the only brick-and-mortar build of the Monadnock Building.
Outside the frame, iron-reinforced frameworks have been used to prevent the building of concrete walls from building inside to prevent the building of a strong building and to prevent the effects of wind.
