From the article linked above:
Here is a blow by blow of the 2017 and 2018 appropriations for the wall (almost all obligated on contracts), extracted from the official press releases on the CBP website (like this: https://www.cbp.gov/newsroom/national-media-release/border-wall-contract-award-arizona):
San Diego, California 14 miles of 18 foot bollards with anti-climb plate are being built (nearing completion), due to finish by May. FY 2017 appropriations. The $147 million contract for this project was awarded to SLSCO, a Texas-based construction corporation.
A second 14 mile layer of 30 foot bollards has been awarded, and just started (February 2019). The contract was awarded on December 20, 2018 to SLSCO Ltd. using CBP’s Fiscal Year (FY) 2018 appropriations. The total contract value, including options, is approximately $287 million (and includes the 15 miles below in Tecate, Andrade and Calexico).
Tecate, California 3 miles of 30 foot bollards contract awarded, should start early 2019.
Andrade, California One mile of 30 foot bollards (one side of the Port of Entry), contract awarded, should start early 2019.
Calexico, California 11 miles of 30 foot bollards East of the Port of Entry, contract awarded, work to start in the Spring (FY18, included above).
Calexico, California 2.25 miles of 30 foot bollards West of the Port of Entry. Completed. FY 2017 appropriations, about $18 million.
Yuma, AZ 27 miles, Contract awarded, construction is scheduled to begin in April 2019. Fiscal Year 2018 appropriations awarded on November 13, 2018 to Barnard Construction Company, Inc. for the base contract of $172 million for approximately 14 miles (plus 13 Option miles), includes 5 miles in Lukeville, (below). Total contract value, including options, is approximately $324 million.
Lukeville, AZ 5 miles Contract awarded, construction is scheduled to begin in April 2019. (included in award above)
Santa Teresa, NM (Western flank/suburb of El Paso) 20 miles of 18 foot bollards with anti-climb plate. Complete. CBP awarded a construction contract January 22 to Barnard Construction of Bozeman, Montana. FY 2017 appropriations. The project cost is approximately $73.3 million.
El Paso, Texas 4 miles of 18 bollards with anti climb plate East from the Port of Entry to Fonseca Drive. Complete. CBP awarded a construction contract June 1, 2018 to West Point Contractors of Tucson, FY 2017 appropriations, 22 million.
Mission, Texas (Western Flank of McAllen Port of Entry) 8 miles of hurricane rated levee wall system, topped with 18 foot bollards. Contract awarded, construction is scheduled to begin in February 2019. This is the area with many of the test cases that were pursuing legal challenges (La Lomita Chapel, National Butterfly Center, Bentsen State Park, Ray Cavasos). (FY) 2018 appropriations. The contract for this project, referred to by CBP as RGV-02, was awarded on November 11, 2018, to SLSCO in the amount of approximately $167M.
Donna/Weslaco, Texas, (Eastern flank of McAllen metro area, East of the Santa Ana Reserve) 6 miles of hurricane rated levee wall system, topped with 18 foot bollards. Contract awarded, construction is scheduled to begin in February 2019. (FY) 2018 appropriation. The contract for this project, referred to by CBP as RGV-03, awarded on October 31, 2018 to SLSCO Ltd in the amount of $145 Million for construction.
Brownsville, Tx Area 7 (with an option for 4 more) automated gates to be constructed, to begin closing the 35 road gaps left in the area during the Bush-era Secure Fence Act barrier construction. (FY) 2017 appropriation. The contract for the first phase of gate construction was awarded on October 3, 2018 to Gideon Contracting, LLC, from San Antonio, Texas in the amount of $3,731,380 for the seven base gates. The contract includes options for four additional gates valued at $1,985,525.
All of this that has been put on contract so far during the Trump Administration totals 115 miles – probably what the President was referring to on Christmas Eve.
The pace of construction this year will be significantly higher than last. In 2018, 35 miles were built over four different segments. Already awarded for this year are 80 miles across thirteen segments (one of the Texas awards is composed of five separate segments).
The $5.7 billion requested for FY 2019 to do 234 miles, would effectively button up the the Rio Grande Valley (~100 miles), Laredo (55 miles), and 75 more miles for the highest priority points on the border – where more than 2/3 of illegal immigrants now cross. That much barrier would make a significant and lasting impact. $8 billion, even more so. After the Rio Grande Valley and Laredo, everywhere else is cheaper and easier to build.
The $1.375 billion appropriated for 2019 may be going toward about 50 miles in the Rio Grande Valley (if informal sources are to be believed), but that is not authoritative. Usually, the announcement of environmental (and other) waivers precedes contract awards by about 10 weeks, and I have not heard of them yet for new segments. I am guessing that in 3-6 months, new segments will be being awarded like like rain falling – maybe earlier if they have prepared well for the funding.
Contracting lead times have been shortening over the the last two years of the program, as would be expected.
