内容简介

Great Building Feats reveals how and why the world's greatest structures were created and how engineering, geographical, technical, and human challenges were overcome during construction. Each building required the best minds of its time. They remain innovative and fascinating in both their creation and appearance. Supports the national curriculum standards Culture; Time, Continuity, and Change; People, Places, and Environments; Individuals, Groups, and Institutions; Power, Authority, and Governance; Science, Technology, and Society; and Global Connections as outlined by the National Council for the Social Sciences. From 1931 to 1935, more than five thousand men worked twenty-four hours a day, seven days a week to complete the Hoover Dam at the border between Arizona and Nevada. Today, the dam provides power and water throughout the Southwest and fuels the growth and economies of many cities and communities.
