This includes trusses, columns, girders, beams, struts, girts, purlins, vertical and horizontal bracing,
bolts, and nuts.
Pipe Racks
& Utility Bridges
This includes steel structures outside the physical boundaries of a major structure, which is used to
support pipe, conduit, and/or cable tray.
Miscellaneous
Steel
This includes handrails, toe plate, grating, checker plate, stairs, ladders, cages, miscellaneous platforms,
pre-mounted ladders and platforms, miscellaneous support steel including scab on supports, “T” and
“H” type supports, trench covers, and Q decking.
Total
Structural Steel
Total Installed Unit Cost (TIUC) for Structural Steel is the weighted average by quantity of
Structural Steels, Pipe Racks & Utility Bridges, Miscellaneous Steels and any other Structural
Steel not included above.
Structural Steel Repetitive Construction
If the project includes multiple similar components that allow construction efficiencies (i.e.
based on learning curve, formwork reuse, etc.), estimate the percentage of the total quantity for
structural steel that was repeated.
Example: The total structural steel quantity for a project is 5,000 MT. The design includes three
identical structural steel frames of 1,000 MT each. There are no other identical components. The
estimated repeated quantity for structural steel is :
3(1,000)- 1,000 MT = 2,000 MT = 40%
5,000 MT 5,000 MT
