Book excerpt: Excerpt from Reports on the Construction of the Piers of the Aqueduct of the Alexandria Canal: Across the Potomac River at Georgetown, District of Columbia, 1835-1840 The subject which next claimed the attention of the engineers was a plan for the proposed work. Having no instructions on this point, we were left entirely to the guidance of our own judgment, and to the influence of the facts which my survey and examinations of the site of the work had brought to view, and these were such as to induce us to give to the plan a character of the utmost stability as it respected the foun dations, and one of equal durability to the superstructure. It was to consist of twelve arches of stone, supported by eleven piers and two abut ments; the arches to be 100 feet span and 25 feet rise; the soffits to be curves of eleven centers; three abutment-piers, being every third pier, to be each 21 feet thick at the springing of the arch; and eight piers of support, each to be 12 feet thick at the Spring ing, the masonry of the land-abutments to be 21 feet thick. This plan was approved of by the president and directors, with the exception of the superstructure, the cost of which, being beyond the limited means of the company, was left for after consideration. The plan was further altered by rejecting the abutment - piers; but eventually these were restored on the recommendation of the engineers. A causeway of earth, 350 feet in length, was substituted for three of the arches at the southern extremity of the work.

Book excerpt: A richly illustrated behind-the-scenes tour of how the nation’s capital was built. In 1790, George Washington and Thomas Jefferson set out to build a new capital for the United States of America in just ten years. The area they selected on the banks of the Potomac River, a spot halfway between the northern and southern states, had few resources or inhabitants. Almost everything needed to build the federal city would have to be brought in, including materials, skilled workers, architects, and engineers. It was a daunting task, and these American Founding Fathers intended to do it without congressional appropriation. Robert J. Kapsch’s beautifully illustrated book chronicles the early planning and construction of our nation’s capital. It shows how Washington, DC, was meant to be not only a government center but a great commercial hub for the receipt and transshipment of goods arriving through the Potomac Canal, then under construction. Picturesque plans would not be enough; the endeavor would require extensive engineering and the work of skilled builders. By studying an extensive library of original documents—from cost estimates to worker time logs to layout plans—Kapsch has assembled a detailed account of the hurdles that complicated this massive project. While there have been many books on the architecture and planning of this iconic city, Building Washington explains the engineering and construction behind it.
