Raising of Chicago

During the 1850s and 1860s engineers carried out a piecemeal raising of the level of central Chicago

. Streets, sidewalks and buildings were either built up or else physically raised up on jacks. This work was paid for both out of the public purse and by private property owners.

Background

 that killed six percent of the city’s population. Sanitary conditions were in no small measure blamed for these deadly outbreaks.

The crisis forced the city's engineers and aldermen to take the drainage problem seriously and after many heated words had been spent—and following at least one false start—a solution eventually materialised. In 1856, engineer Ellis S. Chesbrough's plan for the installation of a city-wide sewerage system was submitted to and adopted by the Common Council. Drains were laid, roads and sidewalks were covered with several feet of soil and refinished, and much of the rest of the city was put on jacks and raised to the new grade.

Earliest raising of a brick building

s to its new grade, which was 6 in 2 in (1.88 m) higher than the old one, “without the slightest injury to the building.” It was the first of more than fifty comparably large masonry buildings to be raised that year. The engineer in charge was a Bostonian Mr James Brown, who went on to partner with longtime Chicago engineer James Hollingsworth; Brown and Hollingsworth became the first and, it seems, the busiest building raising partnership in the city. Before the year was out, they were lifting brick buildings more than 100 feet (30.5 m) long, and the following spring they took the contract to raise a brick block more than twice that length again.

The Row on Lake Street

By 1860 confidence was sufficiently high that a consortium of no fewer than six engineers—including Brown, Hollingsworth and George Pullman

; a solid masonry row of shops, offices, printeries, etc., 320 feet (97.5 m) long, comprising brick and stone buildings, some four stories high, some five, having a footprint taking up almost 1 acres (4,046.9 m²) of space, and an estimated all in weight including hanging sidewalks of thirty five thousand tons. Businesses operating out of these premises were not closed down for the lifting; as the buildings were being raised, people came, went, shopped and worked in them as if nothing out of the ordinary were happening. In five days the entire assembly was elevated 4 in 8 in (1.42 m) clear in the air by a team consisting of six hundred men using six thousand jackscrews, ready for new foundation walls to be built underneath. The spectacle drew crowds of thousands, who were on the final day permitted to walk at the old ground level, among the jacks.

The Tremont House

The following year a team led by Ely, Smith and Pullman raised the Tremont House

This building was luxuriously appointed, was of brick construction, was six stories high, and had a footprint taking up over 1 acres (4,046.9 m²) of space.

—were completely oblivious to the feat as the five hundred men operating their five thousand jackscrews worked under covered trenches. One patron was puzzled to note that the front steps leading from the street into the hotel were becoming steeper every day and that when he checked out, the windows were several feet above his head, whereas before they had been at eye level. This huge hotel, which until just the previous year had been the tallest building in Chicago, was in fact raised fully 6 feet (1.8 m) without a hitch.

The Robbins Building

Another notable feat was the raising of the Robbins Building, an iron building

 150 feet (45.7 m) long, 80 feet (24.4 m) wide and five stories high, located at the corner of South Water Street and Wells Street. This was a very heavy building; its ornate iron frame, its twelve inch (305 mm) thick masonry wall filling, and its “floors filled with heavy goods” made for a weight estimated at 27,000 tons, a large load to raise over a relatively small area. Hollingsworth and Coughlin took the contract and in November 1865 lifted not only the building but also the 230 feet (70.1 m) of stone sidewalk

 outside it. The complete mass of iron and masonry was raised 27.5 inch (0.6985 m), “without the slightest crack or damage.”

Buildings relocated

 were now considered wholly inappropriate to the burgeoning and increasingly wealthy city. Rather than raise them several feet, proprietors often preferred to relocate these old frame buildings, replacing them with new masonry blocks built to the latest grade. Consequently, the practice of putting the old multi-story, intact and furnished wooden buildings—sometimes entire rows of them en bloc—on rollers and moving them to the outskirts of town or to the suburbs was so common as to be considered nothing more than routine traffic. Traveller David Macrae wrote incredulously, “Never a day passed during my stay in the city that I did not meet one or more houses shifting their quarters. One day I met nine.

in the horse cars we had to stop twice to let houses get across.” As discussed above, business did not suffer; shop owners would keep their shops open, even as people had to climb in through a moving front door. Brick buildings also were moved from one location to another, and in 1866, the first of these—a building of two and a half stories—made the short move from Madison Street out to Monroe Street. Later, many other brick buildings were to be rolled much greater distances across Chicago.
