Massachusetts Construction Supervisor License (CSL) Practice Test

Which agency governs the construction of steel bar joists?

1. American Institute of Steel Construction (AISC)

2. Steel Joist Institute (SJI)

3. International Code Council (ICC)

4. National Steel Bridge Alliance (NSBA)

The correct answer is: Steel Joist Institute (SJI)

The Steel Joist Institute (SJI) is the correct answer because it specifically focuses on the design, manufacture, and construction of steel joists and related products. The SJI develops standards and guidelines for the use of steel joists, ensuring safety and performance in construction practices related to this specific type of structural element. Their guidelines are critical for architects, engineers, and constructors who work with steel joists in building projects. The other organizations do play important roles in the broader context of steel construction but do not specifically govern the construction of steel bar joists. For example, the American Institute of Steel Construction (AISC) provides standards and specifications for all types of steel structures, while the International Code Council (ICC) develops regulations for building safety in general, covering a wider array of construction materials. The National Steel Bridge Alliance (NSBA) primarily focuses on steel bridge design and construction rather than on steel joists. Therefore, SJI's specialization directly supports the construction of steel bar joists.
