What's Included
Complete Steel Takeoff
Every structural steel takeoff is 100% drawing-referenced — every member, connection, and deck quantity tied to a specific structural sheet.
Structural Steel Tonnage by Member Type
W-shapes, HSS, angles, channels, plates, and built-up sections — tonnage by member designation, length, and quantity. Organized by floor level and framing zone.
Miscellaneous Metals Takeoff
Stairs, railings, ladders, grating, checkered plate, lintels, shelf angles, embed plates, and all miscellaneous iron — unit counts and linear footage.
Connection Hardware & Anchor Bolts
High-strength bolts (A325/A490) by diameter and length, anchor bolt groups by column base, weld sizes and lengths by joint type.
Decking & Metal Framing
Composite and non-composite floor deck by gauge and span, roof deck by profile and gauge — SF by zone with edge conditions and pour stops.
Structural Steel Erection Scope
Piece count by member type for erection planning, crane pick list, and field bolt quantities — organized to support erection subcontractor bidding.
Excel Workbook + Annotated Markups
Quantities in Excel organized by structural framing zone and level, with color-coded PDF markups tied to specific structural drawing sheets.
Why Choose Us
The Union Estimating Difference
Structural Drawing Expertise
We read AISC-standard structural drawings including connection details, camber diagrams, and erection plans — not just plan views.
Member-Level Accuracy
Every W-shape, HSS, and plate is counted individually from the structural framing plans and schedules — no area-based approximations.
Fabricator & Erector Ready
Deliverables are organized to support both the steel fabricator's shop drawings and the erection subcontractor's field crew planning.
Fixed-Fee Quote Before Work Begins
We review your drawings and provide a firm fee before starting. No hourly billing, no scope creep charges.
48–72 Hour Standard Turnaround
Most structural steel takeoffs are delivered within 48 to 72 hours. Rush delivery available for tight bid deadlines.
Design & Engineering Excluded
We quantify from your supplied drawings. Structural engineering, connection design, and shop drawing preparation are not included.
