According to the CSI MasterFormat, which division covers concrete work?
Correct Answer
B) Division 03
Division 03 in the CSI MasterFormat covers concrete work including cast-in-place concrete, precast concrete, and concrete accessories. Division 02 is site construction, Division 04 is masonry, and Division 05 is metals.
Why This Is the Correct Answer
Division 03 in the CSI MasterFormat is specifically designated for concrete work. This division encompasses all concrete-related construction activities including cast-in-place concrete, precast concrete panels and structural elements, concrete accessories like reinforcing steel and embedded items, concrete restoration, and specialty concrete applications. The CSI MasterFormat is the industry standard organizational system used in construction specifications, and Division 03 has been consistently assigned to concrete work across all versions of the format.
Why the Other Options Are Wrong
Option A: Division 04
Division 04 in the CSI MasterFormat covers masonry work, not concrete. This includes brick, block, stone, and other masonry units along with mortar, grout, and masonry accessories. While masonry and concrete are both structural materials, they are distinctly different construction trades with separate divisions.
Option C: Division 02
Division 02 covers existing conditions and site construction work such as selective demolition, site preparation, earthwork, utilities, and site improvements. This division deals with site work that occurs before building construction begins, not concrete work which is part of the building structure itself.
Option D: Division 05
Division 05 in the CSI MasterFormat is dedicated to metals, including structural steel, metal joists, metal decking, cold-formed metal framing, and metal fabrications. While metal reinforcement is used in concrete, the metal components themselves are classified under Division 05, not the concrete work.
