Construction Begins on Louvre Abu Dhabi Dome

The first piece of the 180-meter diameter Louvre Abu Dhabi dome was lifted into place on Wednesday.  The section was one of 85 preassembled structures needed to be raised in order to complete the dome.  The original plan to construct the museum dome called for a 1600-ton crane to lift each segment and connect them in a counter-clockwise direction.  However, that crane, nicknamed Megatron after the Transformers character, was delayed at another project is currently arriving in pieces at the construction site.  Instead, crane operators will use a 600-ton crane until the bigger model can be assembled to avoid any delays to the project.

The Cleveland National Forest Foundation, a small group of environmental advocates, filed a lawsuit against Caltrans on Wednesday over the plans to expand I-5 in the San Diego area.  The lawsuit claims the freeway expansion would lead to “an enormous surge in greenhouse gas emissions.”  Caltrans Final Environmental Impact Report, which was signed on October 23, 2013, states that the express lanes expansion project is the best way to serve the 300,000 daily trips along the freeway by 2030 as it has the least impact on natural resources, requires fewest property relocations, and has the lowest construction costs.

Westfield Group paid $800 million last week to buy 50% of the retail space in the new World Trade Center.  The company had previously purchased the other 50% of space for $600 million two years ago.  Westfield Group is a mall developer and operator and currently own shopping areas in London, San Fransisco, and Los Angeles.  The New York and New Jersey Port Authority owns the 16-acre World Trade Center site, and it will use part of the $1.4 billion in revenue from the sales to fund infrastructure in the region.  According to Port Authoirty chairman David Samson, Westfield’s investment will allow the Port authority to “refocus agency resources on our core transportation mission.”  No specific announcements have been made about where this funding will be used.

1,000 Foot Bay Front Tower in Miami Proposed

In late November, a Miami developer announced his plans for an observation and amusement tower on the Miami bay front. The tower, referred to as the SkyRise Miami tower, would be 1,000 feet tall and include dining, observation decks, a ballroom and an assortment of amusement attractions. The building is designed as two structures attached at the top through a curve giving it a hairpin-like appearance. This unique design, which is open in the middle, allows the structure to withstand hurricane force wind.

The federal Surface Transportation Board rejected the California High Speed Rail Authority’s approval request for a 114-mile section of the rail line between Fresno and Bakersfield on Wednesday.  The board is demanding an extensive environmental review before the approval will be granted.  Currently, only 28 miles of the track have environmental approval.  Officials from the rail authority are brushing off the ruling as nothing more than a minor setback and that the media is misreporting its significance. However, others see it as another major delay in an already over-budget and slow moving project.
