Hallsville Senior High School in northeast Texas won the SJI 2010 Design Award in the non-industrial category. The 400,000 sq. ft. structure includes a Fine Arts, Science, Career and Technical Education, and Academic facilities including a gymnasium and theatre. The engineering firm of Unified Building Sciences & Engineering (an AISC member) was awarded a $2,000 scholarship in the company’s name to provide to a school of their choice.

Some notable reasons this project won are listed below.

The steel joist system produced by AISC Member Nucor, Vulcraft Group, created an economical and efficient structure. In addition, using this system eliminated the need for a vertical bracing system on the project.

Another interesting component of this project was that the roof in the competition gymnasium was crafted from a 194 ft. span, 10 ft. deep double arched custom joist system that was field spliced at mid-span.
