Agency plans to award Mexico border wall contracts by April

The US Customs and Border Protection has said that it plans to start awarding contracts by mid-April for President Donald Trump's proposed border wall with Mexico, signaling that he is aggressively pursuing plans to erect "a great wall" along the 2,000-mile border.
The agency said it will request bids on or around March 6 and that companies would have to submit "concept papers" to design and build prototypes by March 10, according to a website for federal contractors. The field of candidates will be narrowed by March 20 and finalists must submit offers with their proposed costs by March 24.

The president told the Conservative Political Action Conference on Friday that construction will start "very soon" and is "way, way, way ahead of schedule."
The agency's notice gave no details on where the wall would be built first and how many miles would be covered initially. Homeland Security Secretary John Kelly has sought employees' opinions during border tours of California, Arizona and Texas.
It's unclear how soon Congress would provide funding and how much. The Government Accountability Office estimates a wall would cost on average USD 6.5 million a mile for a fence to keep out people who try to enter on foot and USD 1.8 million a mile for vehicle barriers. There are currently 354 miles of pedestrian fencing and 300 miles of vehicle barriers.

Republican leaders in Congress have said Trump's wall would cost between USD 12-15 billion. Trump has suggested USD 12 billion.
An internal Homeland Security Department report prepared for Kelly estimates the cost of extending the wall along the entire U.S.-Mexico border at about USD 21 billion.
