Major Engineering Projects in Utah

This overview explores two significant engineering projects in Utah: the reconstruction of the Utah State Capitol and the operations of the Kennecott Copper Mine. The Capitol, originally built in 1916, underwent major renovations between 2004-2008 to meet seismic codes and ensure safety. Meanwhile, Kennecott has a rich history, starting as a copper company in 1903 and becoming the largest private economic driver in Utah. It remains a crucial player in copper production, with mining output contributing significantly to the state's economy.

  1. By: Kyle Hungerford Major Engineering Projects in Utah

  2. 2 Major projects/structures • Utah State Capitol rebuild • Kennecott copper mine

  3. Utah State Capitol

  4. History • Built in 1916 • Designed by local architect Richard K. A. Kletting • Budget set at $2.5 million • The capitol was to be built of stone, with a concrete and steel superstructure • Built before knowledge of earthquake dangers. Therefore did not meet seismic building codes

  5. Wasatch Fault

  6. 2004-2008 renovation and seismic upgrade • 2 options: either rebuild the capitol from scratch (a cost of $1 billion) or rebuild the foundation so that it meets seismic building codes (cost of $260 million) • Installed 265 base isolators • Added new concrete walls to stiffen the building causing concentration of movement within the isolators

  7. Base isolation system

  8. Kennecott

  9. History • 1903 – started as Utah copper Company • 1915 – Kennecott Copper Corporation (KCC) was incorporated as a holding company. Over 8 years raised its holdings to 77% • 1936 – KCC purchased 100% of Utah Copper Company • 1981 – Standard Oil Company of Ohio (Sohio) took over. British Petroleum (BP) owned 53% of Sohio at the time. • 1989 – BP sells assests and facilities to Rio Tinto Zinc (RTZ)

  10. Highlights • Largest private economic driver in Utah • Largest man made excavation on earth • Second largest copper producer in the United states • Since operations began it has produced more copper than any other mine (more than 19 million tons)

  11. 4 step process • Mining->Concentrating->Smelting-> Refining

  12. Products (annually) • 300,000 tons of copper (worth about $1,806,000,000) • 400,000 ounces of gold (worth about $528,200,000) • 4 million ounces of silver (worth about $40,840,000) • 30 million pounds of molybdenum (worth about $360,000,000) • 1 million tons of sulfuric acid (worth about $250,000,000)
