The Middle East Region is working to complete as many as 117 construction projects over the next twenty years. These projects, estimated at more than $1 trillion, will improve existing infrastructure and at the same time will generate over 1 million construction jobs. One nation that has turned out to be the key driver of these large investment is Qatar, the city that will host FIFA 2022 World Cup. Qatar will peak construction projects in 2016, year on which $144 billion in construction projects are expected to be underway. The region has seen an upward trend in large international construction firms bidding and working on these projects, as they can provide experience and strong balance sheets that mitigate risks during the construction process.

The Bay Delta Conservation Plan
, a huge construction project that could solve California water supply problem, is asking for more than $1 billion as part of the planning process. This amount of money is needed to complete analysis and assessment on the viability of the project, so it can be started later during 2017. Actual design and planning of the water tunnel system is only at 10% after spending more than $240 million during the past 7 years. The proposal calls for two large tunnels, 40 feet in diameter and 35 miles long, Bay Delta Conservation Plan, that would be excavated using a circular cutterhead that mines through the soil at approximately 150 feet below the surface. Material excavated
during construction, often referred to as "tunnel muck" , has been identified for many possible reuses, including strengthening levees, raising subsiding Delta islands, and restoring natural habitats, among other uses.

The Vogtle Plant, Georgia's latest nuclear plant, reached an important milestone when the fourth concrete foundation was poured last week. The Vogtle plant will be the only four-unit nuclear power plant in the USA. Last week the concrete contractor completed the 7,000 cubic yard mat, where the reactor will be placed once the concrete cures. The concrete was poured in only 41 hours, matching the world's record for this type of reactor. These new reactors are among the first built in the U.S. in three decades.

Two skyscrapers proposed to be built in Hollywood, are facing serious delays as a group of citizen have filed a lawsuit to discuss the proximity to a quake fault location. The Millenium Towers could be located within 15 meters of a fault line, violating the earthquake safety
law that was passed after the 6.6-magnitude San Fernando Valley earthquake in 1971. The Alquist-Priolo Earthquake Fault Zoning act
, requires new buildings located near faults mapped by the state to perform extensive testing to prove their structures do not sit on top of active faults. Citizens and other professionals are claiming that city could act faster and complete all 300 maps missing showing quake fault locations in order to obtain their permits to start new buildings.
