State officials are awarding a contract to oversee construction of a border barrier to a joint venture between an engineering firm and a design firm. The Texas Facilities Commission voted on Thursday to approve the 11 million dollar contract for Michael Baker International and Huitt-Zollars. Pennsylvania-based Michael Baker has Texas offices in San Antonio, Austin, Houston, and Dallas, and has helped build more than 500-miles of border wall. Dallas-based Huitt-Zollars has designed Border Patrol stations in Texas and California.
