When the United States entered the First World War in April 1917, the nation had a permanent army of only 100,000 soldiers. Efforts to recruit and form a 2 million strong struggle and convert the economy to serve the war effort were consumed. The federal government assumed high -reaching powers, nationalizing the railways and establishing coal prices. He assigned much of the country’s steel production for a shipbuilding effort. More than 100,000 trunks entered the forest to harvest fir for airplane bodies. All this had a great impact on the construction.
The United States Army QuarterMaster Department was commissioned to build 16 training camps, each between 20,000 and 40,000 residents. The contractors were contracted on a safe way to build them in just over two months. Each camp consisted of up to 1,200 buildings, which needed 600 million feet of wood in total. An article in the construction at the Base of Presidio de San Francisco said that “an army of 600 carpenters and assistants built 210 complete buildings in 18 working days.” Another article from the ENR described a contractor who was awarded a contract for a training camp in Fort Sheridan in Illinois on April 28, placing an order for 1.4 million feet of wood the next day, the Fortes provider placed the total amount on a 50 car train the next day and his arrival on May 1.
A staff of 5,000 camps built in Massachusetts in a place of 8,000 hectares, with 22 sawmills supplying the project. Twenty kilometers were completed in the first weeks. At Dodge A Iowa, 1.25 miles of sewer line and 0.75 miles of water line a day were put.
An ENR report described an engineering regiment of 1,200 men in formation in Monterey, California, were enrolled in the creation of military maps, the building’s building and the fortification of the Timber and Pontoon bridge. Specialized merchants would just assign occupational specialties such as surveyors and projections, miners and quarries, carpenters, mechanics, axen and equipment.
An engineering regiment in New York in 1917 requested “powdered men, carpenters, wharf builders, blacksmiths, plumbers, electricians, engine men (steam and gas), machinists, masons, calls, rigor, horse shops, seixers, chefs, chuffeurs, searches and surveyors.” The U.S. provided 1.5 million horses to war efforts, which transported supplies and removed artillery.
Reports to the ENR of the leading engineering schools emphasized that subclassists were advised to stay in their studies, and the Classmen Upper thought to leave the university for military service should be considered in industry, as the country’s manufacturing capacity was as important in the war as the army in the field. A representative of the Massachusetts Institute of Technology stated: “Modern developments have put war on the skill of engineers, mechanics, electrical and chemicals, with the qualities of the struggle of armies.”
An article entitled “Government construction operations need a strong central control” described a sophisticated graphic developed by the Ordnance office with a time of overlapping steps needed to produce cartridges. The progress graph allows managers to identify and correct delays, a precursor to the method of delivery of the critical route project.
The municipal public works departments reduced their construction activities, redirect materials and labor for work related to war. A seizure on road material promulgated by the National Defense Council in November 1917 caused most of the road construction to stop.
A long article discussed work supply problems. Groups of immigrant workers, led by a performer, would leave a job with a short warning, as there was abundant work on railway projects. The workers who worked alone were often restless. “In some elevation work on the Chicago track made by a railway company, 2,870 men were occupied for a period of six months to maintain a workforce of about 400. The average time spent on work was less than five days for each man.” The turnover was attributed to drinking or that many workers were transients who came from work at work, helped by employment agencies offering free transportation to other jobs.
The labor riots promoted a series of publisher Enr in 1918, which provided that the work “would demand and obtain a greater part of the benefits of industry” and would seek better working conditions. The publishers urged the owners to commit. Weeks later, the War Work Conference Board acknowledged the right to organize and instituted the eight -hour working day, a condition only achieved by a few unions earlier.
The Government created the Ferrocarrils War Board, which operated all lines in the East of the United States as a single entity of 120,000 miles, grouping its facilities to better manage the abnormally high volume of traffic. Antimonopoly laws and 2 million railway workers, the largest industry in the country, became public employees.
A drop -of -naval construction effort started. As steel was needed elsewhere, it was decided that most of the cargo ships would be made of wood. Gen. Goethals, Head of the Emergency Fleet Corp., Issued contracts to dozens of Shipyards, with Delivery of Finished Vessels Expected Throughout 1918. Bread. These Yards, with a Total of 90 SHIPWAYS, Built Vessels with Simpified, Rectangular Almost Hulls, Using Structural Steel Forms made of bridge stores and structural steel. It was expected that this line of line of assembly would significantly shorten the times of the ship.
Insufficient home near the Bristol garden needed a quick program to build 3,000 housing units in six weeks, so that the entire workforce of 6,000 people could be accommodated. The construction of the Hog Island floor plant was reduced due to the serious winter time, inadequate railway crawling and an isolated location that made it difficult to hire and withhold workers. Completed ships began to launch in large quantities in the summer of 1918, finally overcoming the tonnage of allied ships sunk by the Germans, but the great leap of shipbuilding was too late to materially affect the war effort.
The first article Enr, Unbylined, on the activities of American troops in France, described an extensive 100-hectare American arrangement base, which included engine stores for artillery review and shops for repair trucks and tractors. The 600 -foot buildings were mounted from 20 feet X 35 feet made of wavy metal, brought from the United States Another article outlined a program that built portable homes for troops. The components of the buildings of 20 x 217 feet were manufactured in Louisiana, Mississippi and Texas, sent to France and they were quickly mounted with screws.
Enr sent his managing publisher, Robert K. Tomlin Jr., to cover the war from a construction perspective. Tomlin was a degraded engineer who had worked on railway and water tunnel projects before joining the Enr staff. He was the first North -American engineer to act as a war correspondent. He traveled to France in December 2017 and wrote dozens of articles for the next eight months. In September 2018 he was commissioned as captain to the Corps of Engineers and assigned to the Technical Information Office. After the war, he returned to Enr.
One of his first articles exhibited a large 60 cm caliber railway network under construction of the American engineering regiments, whose function was to “carry out as close to the front as possible ammunition, fodder, road material, portions, wood and fuel and transport troops and wounded men”. Given the narrow caliber, it could be easily repaired after damage to artillery attacks.
Tomlin visited a French quarry, saying that much of the work was done by labor, unlike the North -American quarries who used more machinery. Three months later he visited a United States quarry recently established in France with a machine plant supplied to the United States, which produced much larger production.
At a Paris ammunition plant, 9,000 women produced 50,000 artillery shells a day. Tomlin wrote an article about his experience of being in Paris while undergoing bombings by a long -range German gun and aerial attacks.
He reported on a key advance deposit, which he called “the great arterial system of army traffic whose heart is in the basins of our army and in the railway gardens”. It had 19 warehouses, each of 50 feet x 500 feet, railway gardens consisting of 50 miles of track and two structures of ammunition of steel. It was one of the most valuable railway and management centers of war effort.
Other holders of their articles, such as “American forest units, work 53 sections of French wooden earth” and “American Army water projects in France, a number of about four hundred” indicate the extent of engineers’ efforts to support American forces as 250,000 American soldiers arrived in France each month.
The United States Army Engineers Corps consisted of 256 officers and 2,100 men entered when the United States entered the war in April 1917. In June 1918, there were 7,800 engineering officers and 200,000 enrolled men.
