The deadline for submissions to build President Donald Trump’s Mexico border wall has been extended until March 20.
The US Department of Homeland Security, Customs and Border Protection has also updated its notice to give bidders more information about the project, estimated to cost $21bn.
“For planning we anticipate procuring concrete wall structures, nominally 30 feet [nine metres] tall, that will meet requirements for aesthetics, anti-climbing, and resistance to tampering or damage,” says the notice.
Those remaining will have to submit a full RFP, including pricing, by 3 May 2017 – again later than the original mid-April deadline.
“The intent of this procurement is to acquire and evaluate available wall prototypes and provide some initial construction of some wall segments, but is not intended as the vehicle for the procurement of the total wall solution for the border with Mexico,” the notice says.
A variety of satirical designs for the barrier have already been put forward. They include a pink wall inspired by the work of Mexican architect Luis Barragán and a spoof of an IKEA flat-pack furniture kit.
