How we estimate structural steel
A structural steel estimate is primarily a tonnage exercise, but connection complexity, member count and erection access drive the cost as much as weight. We list members by shape and length from framing plans, and count connections, base plates and embeds separately.
Metal deck, shear studs and miscellaneous metals such as lintels, stairs and railings are taken off as separate line items so they can be checked against the structural and architectural sets.
What we measure
- Wide-flange beams, columns, HSS and angles by shape
- Bracing, moment and shear connections (counted by type)
- Base plates, anchor bolts and embedded plates
- Composite and roof metal deck, shear studs
- Lintels, loose angles and miscellaneous metals
- Steel stairs, landings and railings where drawn
What to send us
- Structural framing plans, sections and connection details
- Column schedule and base plate details
- Architectural drawings for stairs, rails and misc. metals
- Specifications for steel grades, coatings and fireproofing
What you receive
- Member list with shape, length and weight
- Tonnage summary by area or level
- Deck and stud quantities
- Material, fabrication and erection cost breakdown
- Assumptions and exclusions
The exact contents and format are agreed when we quote the estimate.
Units of measure
- United States and Canada
- Tons, pounds per foot, SF of deck
- United Kingdom (and metric projects)
- Tonnes, kg/m, m² of deck
