REBUILDING Iraq after 25 years of rule by Saddam Hussein and the war that overthrew his government will be one of
the USA’ foreign policy priorities in the coming years. By some estimates, the cost of reconstructing Iraq ranges from $50
billion to $100 billion. However, substantial disagreement exists about that cost, as well as about how much aid from the
international community may be needed to rebuild the country, whether that aid should take the form of grants or loans, how
much the USA should contribute, and how much Iraq can finance itself from its future sources of revenue. To assess the scope
of the reconstruction job, the Coalition Provisional Authority (CPA), the United Nations and World Bank, and the Bechtel
Corporation (under contract to the U.S. Agency for International Development) carried out surveys of Iraq’s needs in 2003.
The needs that they identified are mainly associated with the deterioration of Iraqi infrastructure that has occurred since Iraq
invaded Iran in 1980. The surveys indicate that although sanctions imposed during the 1990s and damage from recent postwar
looting have worsened the condition of Iraq’s infrastructure, they are not the most significant cause of its poor state.

Evaluation of Roof Bolting Requirements Based on In-Mine Roof Bolter Drilling. Quarterly Technical Progress Report,
July 1, 2001-September 30, 2001

Roof bolting is the most popular method for underground openings in the mining industry, especially in the bedded
deposits such as coal, potash, salt etc. In fact, all U.S. underground coal mine entries are roof-bolted as required by law.
However, roof falls still occur frequently in the roof bolted entries. The two possible reasons are: the lack of knowledge of
and technology to detect the roof geological conditions in advance of mining, and lack of roof bolting design criteria for
modern roof bolting systems. This research is to develop a method for predicting the roof geology and stability condition in
real time during roof bolting operation. Based on such information, roof bolting design criteria for modern roof bolting
systems will be developed for implementation in real time.

Proceeedings of the U.S.-Japan Workshop on Earthquake Resistant Design of Lifeline Facilities and Countermeasures
against Soil Liquefaction (8th)
Hamada, M.; Bardet, J. P.; ORourke, T. D.; Jun. 30, 2003; In English
Report No.(s): PB2004-104386; MCEER-03-0003; No Copyright; Avail: National Technical Information Service (NTIS)
The proceedings of this workshop are part of a longstanding US-Japan cooperative research activity that focuses on
earthquake resistant design of lifeline facilities and countermeasures against soil liquefaction. Since its inception, this activity
has assisted other research agendas, such as cooperative research among the U.S. Earthquake Engineering Research Centers
and the U.S.-Japan Cooperative Research Program on Urban Earthquake Disaster Mitigation. In the future, US-Japan
cooperative research on lifelines and liquefaction will benefit from collaborative experimentation and analytical modeling at
many of the superb testing facilities both in Japan and within the George E. Brown, Jr. Network for Earthquake Engineering
Simulation (NEES).
