Structural Steel Estimating Servicesfor Fabricators, Erectors, and GCs
We take off beams, columns, bracing, plates, and connection material from your drawings. If you need a full number, we price the shop and field work too.
Reviews from contractors and subcontractors who send us their bid estimates, takeoffs, and shop drawings.
Trustpilot
Review summary: Bart needed shop drawings on a tight schedule. The team discussed the project the same day, delivered drawings within a week, and completed minor revisions the following day. He praised their understanding of the scope, quick responses and progress updates.
Review summary: Ludin appreciated the professional team, their patience and guidance, and recommended BidAccurate for takeoff and shop drawing projects.
Fabricators, erectors, general contractors, and steel suppliers across the US use our structural steel estimating services when they need tonnage they can defend. We read the structural set against the architectural drawings, count and weigh every member, and break out the connection material that a single tonnage figure tends to hide.
Beams, columns, HSS, bracing, plates, bolts, welds, and anchor rods are in the takeoff by default. Joists, deck, stairs, rails, and misc metals are different. Those packages get split between subs all the time, so we confirm who carries them before we count them.

What's Included in Our Structural Steel Estimating Services
We scope each job from the drawings, specs, addenda, and bid form you send. Below is what a typical steel package covers. A fabricator, an erector, and a GC each need a different slice of it, so we set the breakdown to match your bid.
Structural Members and Framing
We list each piece by mark, shape, grade, and length, then roll the weights up by level or erection sequence if the drawings give us enough to do it.
W-shape beams, girders, and columns
HSS, pipe, channels, angles, tees, and built-up members
Bracing, trusses, lintels, kickers, and support steel
Crane beams, screen framing, dunnage, and equipment supports
Connections and Accessories
Connection material comes off the typical details and connection schedules. Where connections are delegated to the fabricator's engineer, we carry a stated allowance and write down how we sized it.
Shear plates, clip angles, end plates, gussets, and stiffeners
Base plates, bearing plates, cap plates, and splice plates
High-strength bolts, nuts, washers, and anchor rods
Welds, shear studs, headed anchors, and connection allowances
Fabrication and Shop Work
Need shop pricing? Cutting, drilling, fitting, welding, and coating each get their own lines, so your shop rates land where they belong.
Sawing, coping, drilling, punching, fit-up, and shop welding
Plate cutting, beveling, cambering, rolling, and assembly
Shop drawings, detailing, material handling, and quality control
Galvanizing, shop primer, paint systems, and touch-up allowances
Erection and Field Activities
Field hours depend on how the frame goes up. We organize this part by erection sequence, site access, and whether connections are bolted or welded in the field.
Unloading, sorting, hoisting, plumbing, and temporary bracing
Field bolting, field welding, decking support, and punch work
Crane, lift, rigging, welding equipment, and mobilization
Travel, permits, protection, and cleanup
Related Metals and Scope Boundaries
Joists, deck, and misc metals often go to a different sub. Once you tell us how the job is split, we include them, leave them out, or carry an allowance.
Open-web steel joists, joist girders, bridging, and accessories
Roof deck, floor deck, pour stops, closures, and deck fasteners
Stairs, ladders, rails, grating, embeds, and miscellaneous metals
Fireproofing, field painting, engineering, testing, and permits
Measurement and Reporting
Units follow how each item is bought or priced. The assumptions behind them are written into the report.
Tons or pounds (LB) for members, plates, and connection material
Linear feet (LF) for members, welds, deck edges, and rails
Square feet (SF) for deck, grating, coatings, and fireproofing
Each (EA), labor hours, crane days, and other agreed bid units
Need a Steel Number Before Bid Day?
Send the plans, specs, addenda, and bid date, plus any pricing you want used. We'll look over the Division 05 scope and tell you what we'd measure and how we'd report it.
We read the structural set alongside the architectural details, specs, and addenda. Lintels, canopy framing, and roof screen steel often show up there and nowhere on the framing plans.
Less Time Scaling Drawings
Your estimator starts from counted members and weighed plates instead of a blank set, and spends the time on pricing.
Lists Your Supplier Can Quote
Material is grouped by shape, grade, and length. That is how a mill or service center wants to see a quote request.
Fewer Dropped Items
Base plates, anchor rods, shear studs, touch-up paint, and temporary bracing are easy to leave out of a steel bid. We check for each of them before the package goes out.
Markups You Can Check
Measured members are color-coded on the drawings, and every line in the workbook carries a sheet reference.
Your Rates and Template
Send your steel quotes, shop and field labor rates, crane costs, and waste factors. We build the estimate on your numbers, in your bid template.
Why Choose BidAccurate for Structural Steel Estimating?
Frame tonnage is only part of a steel price. Connections, shop hours, coatings, freight, and crane time can move the number a lot, so each one stays on its own line.
01
The Whole Set, Read Together
Member schedules, sections, and connection notes don't always agree with the plans. We read them as one set and log the conflicts for you.
02
Weight and Piece-Level Detail
Group members by mark, grade, level, or erection sequence. Pick whatever matches how you buy steel and price labor.
03
Connections Stay Visible
Plates, stiffeners, bolts, and welds get their own lines. A connection allowance, if we carry one, is labeled as an allowance.
04
Scope You Can Audit
Exclusions and assumptions are listed with drawing references. Your estimator can see why a number is what it is, and change it.
05
Set Up Your Way
Excel and PDF, organized by your cost codes, bid items, fabrication sequence, or erection zones.
06
Addenda Updates
Send the revised set. We compare it with the last one, mark what changed in the steel, and update the takeoff under the revision scope we agree on.
Our Structural Steel Takeoff and Estimating Process
Five steps, from the day you send the drawings to the day you have a steel package you can price and check.
1
Send the Drawings
Upload the structural and architectural sets, Division 05 specs, addenda, and bid form. Include the project location, the bid date, and any connection design information you have.
2
Confirm the Steel Scope
Is it the frame only, or joists, deck, and misc metals too? We settle that with you, along with connection assumptions, alternates, and the report layout.
3
Count, Measure, Weigh
We take off members, plates, bolts, welds, anchors, and coatings, then sort them into the breakdown we agreed on.
4
Cross-Check the Set
Quantities get checked against sections, details, and specs. Gaps and conflicts go on a list for you to review.
5
Deliver the Bid Package
You get the Excel or PDF reports and marked-up drawings. If you asked for pricing, material, fabrication, erection, and equipment costs are in there too.

What do you need from us to estimate structural steel?
The structural and architectural drawings, Division 05 specs, schedules, addenda, and bid form, plus the project location and bid date. If connections are delegated to the fabricator's engineer, send whatever design criteria you have. For a priced estimate, add your steel quotes, shop and field labor rates, equipment rates, and cost codes.
What's included in a structural steel takeoff?
Beams, columns, girders, bracing, HSS, angles, channels, plates, bolts, welds, shear studs, base plates, and anchor rods, along with coatings and marked-up drawings. Joists, deck, stairs, rails, grating, and misc metals are handled job by job. We include them, leave them out, or break them out separately depending on how your bid package is set up.
Is a steel takeoff the same as a steel estimate?
Not quite. The takeoff is the quantities: members, weights, connection material, and accessories. The estimate puts costs on those quantities, meaning material prices, shop and field labor, equipment, coatings, and freight. Overhead, profit, taxes, and allowances go on top if you want them carried.
How do you report structural steel quantities?
Members and plates are reported in tons or pounds, with piece counts and lengths. Bolts, anchors, and studs are counted EA. Welds go in LF, deck and coatings in SF. We add labor hours or crane days if you need them. You pick the breakdown: by mark, shape, grade, level, zone, or erection sequence.
What file formats do you deliver for a steel estimate?
Usually an Excel workbook, a PDF report, and color-coded PDF markups of the drawings. If you have your own spreadsheet, cost codes, or a preferred fabrication or erection breakdown, send it before we start and we'll work to it.
Can you update a steel estimate after an addendum?
Yes. Send the revised drawings and specs with a note on what you need updated. We compare them with the prior set and revise the affected members and scope. How long that takes depends on how much changed.
Can you use our own steel quotes and labor rates?
Yes. Send mill, service center, joist, deck, galvanizing, freight, or crane quotes, along with your shop and field rates, production assumptions, and markups. When those are part of the agreed scope, we build the estimate on your numbers.
How long does a structural steel estimate take?
It depends on the size of the frame, how complex the connections are, how complete the drawings are, and how much related metals work is in the package. Pricing detail and addenda matter too. We look at the documents first, then give you a delivery date.
