Precision Structural Steel Estimating & Takeoffs
Comprehensive weight modeling and material takeoffs for steel fabricators, erectors, and general contractors. We calculate measured beam linear footages, column weights, open-web joists, composite metal deck, connection hardware, and miscellaneous stairs.
Structural Steel and Metals: quantities, checks and quote requirements
Steel takeoffs list members by shape and length with weights, connections, base plates and anchor rods, metal deck, joists, and miscellaneous metals such as stairs and railings.
Measurement and reporting basis
- Beams, columns and bracing by shape (TON)
- Connections, plates and anchor rods
- Joists and metal deck (SF)
- Stairs, railings and miscellaneous metals
- Shop primer and field touch-up
Documents to include
- Structural framing plans and details
- Connection design criteria
- Steel and deck specifications
Also identify the current revision, addenda, project ZIP code, requested trades and bid deadline.
A scope check before pricing
List member shape, length and weight basis before totaling LB or TON. Separate joists, deck area, connections and miscellaneous metals so a connection allowance cannot be counted twice.
Scope limits: Connection engineering, shop drawings, welding procedures and erection planning are outside a standard takeoff.
The written quote defines the deliverables and revision coverage. Measured quantities and drawing markups can be supplied for the agreed scope; a priced estimate adds the identified material, labor and equipment cost basis. Missing information is recorded as a clarification or allowance.
Send the documents above for a written quote confirming the scope, fee and delivery date after document review. Indicate whether you need quantities only, a priced estimate or a review of an existing bid.

Structural steel estimating services provide precise quantification of structural steel poundage (lbs) and tonnage (tons) for steel fabricators and general contractors. An expert takeoff references AISC weight tables to compute linear weights for wide-flange beams, HSS columns, joists, and corrugated metal decking—incorporating connection allowances, shop primer coats, anchor bolt layouts, and field erection hours.
Complete CSI Division 05 Structural Metals Scope
Our senior steel estimators quantify all aspects of heavy framing, open-web joists, decking, and miscellaneous fabrications:
Structural Steel Framing
AISC wide-flange beams, columns, channels, angles, moment connections, base plates, and anchor bolts.
Steel Joist Framing
Open-web steel joists (K, LH, DLH series), joist girders, diagonal bridging lines, and bearing attachments.
Steel Decking
Composite floor decks (1.5", 2", 3"), non-composite form deck, roof decks (Type A, B, F, N), and pour stops.
Cold-Formed Metal Framing
Light-gauge structural studs, curtain wall bypass framing, slotted track deflection joints, and headers.
Metal Fabrications (Misc Metals)
Structural stairs, pipe railings, ship ladders, elevator sump grates, bollards, and loose lintels.
Common Work Results for Metals
Shop primer coatings, hot-dip galvanizing, field welding inspection allowances, and structural bolting.

Our 4-Step Forensic Steel Methodology
How we eliminate bidding blind spots and protect your profit margins on bid day:
Framing Plan Audit
We review structural framing plans, column schedules, moment connection details, and structural general notes.
AISC Weight Modeling
We extract measured member lengths, cross-reference AISC poundage per foot, and calculate total mill purchase poundage.
Connections & Decking
We quantify shear tabs, moment plates, base plates, anchor bolts, shear studs, pour stops, and metal deck square footage.
Pricing & QA Review
We apply documented labor assumptions and mill pricing quotes. A senior steel estimator audits the entire package.
Frequently Asked Questions About Structural Steel Estimating
What is included in your structural steel estimating and takeoff services?
Our structural steel takeoffs include measured poundage and tonnage for AISC wide-flange beams (W-shapes), hollow structural sections (HSS tube columns), channels (C-shapes), angles (L-shapes), open-web steel joists (K/LH/DLH series), corrugated metal roof & floor decking (1.5", 2", 3" composite/non-composite), base plates, anchor bolts, shear tab connections, moment connections, bracing rods, and miscellaneous metals (stairs, ladders, pan treads, pipe guardrails).
How do you calculate structural steel weight and connection allowances?
We cross-reference beam and column schedules against the AISC Steel Construction Manual to extract measured linear weights (lbs/ft). We calculate total tonnage and apply standard 5-10% connection allowances for shear plates, stiffeners, gusset plates, shop welds, and ASTM A325/A490 structural bolts.
Do you quantify miscellaneous metals, ornamental steel, and stairs?
Yes. We quantify Division 05 50 00 miscellaneous metal packages including structural egress stairs (stringers, diamond plate / concrete pan treads, landings), pipe railings (ADA compliant 1-1/2" OD), ships ladders, roof access ladders with safety cages, elevator hoist beams, bollards, and lintels.
How do you estimate primer coatings, galvanizing, and intumescent fireproofing?
We calculate surface area square footages for standard shop primer coatings (SP-2/SP-3 hand/power tool clean), hot-dip galvanizing poundage per ASTM A123, and intumescent fire-resistive coatings based on member W/D (weight-to-perimeter) ratios.
What is your turnaround time for a structural steel takeoff?
Delivery depends on the drawing set, requested trade scope, pricing requirements and bid deadline. The delivery date, scope and revision coverage are confirmed in the written quote after document review.
What software do you use for steel quantity takeoffs?
We use PlanSwift, Tekla Structures, SDS2, Bluebeam Revu, and custom steel formula spreadsheets, delivering fully editable, formula-driven Excel schedules structured by CSI Division 05.
How do you price steel fabrication labor, shop welding, and erection hours?
We apply documented client or supplier pricing inputs or your shop fabrication hourly rates, separating raw mill steel costs from shop fabrication labor hours, freight shipping loads, and field crane/rigging erection crews.
Can general contractors use your steel estimates for bid leveling?
Yes. General contractors use our independent steel takeoffs to verify fabricator tonnage numbers, check for missing moment connection plates or deck edge angles, and ensure fair sub-tier pricing on bid day.
