Illinois project estimating
Structural Steel Estimating Services in Illinois
F&K prepares structural steel takeoffs for Illinois fabricators, erectors and general contractors working from issued structural drawings. The scope distinguishes member quantities from connections, coatings, decking and erection responsibilities. Send the framing plans and specifications so the quote reflects whether you need a material list, fabrication budget or a broader installed-cost estimate.

Keep fabrication and field erection on separate cost bases
Illinois public-work pricing can require county-specific prevailing-wage inputs for applicable field activities. The Illinois Department of Labor publishes the schedules to review. An estimate should identify the project county and field-work classification basis rather than apply one blended labor figure to every steel item. Shop fabrication and field erection should remain distinct, with any legal coverage question referred to the responsible contracting team.
For a renovation, existing framing dimensions and connection conditions may require investigation before a firm fabrication quantity is available. A new warehouse can have a different set of issues: joist supplier scope, deck openings, crane setup and delivery sequencing. These conditions follow the actual Illinois project site and contract. They are not captured simply by multiplying all steel tonnage by a generic regional installation rate.
What the takeoff can include
Primary members
Count beams, columns and braces by section, length and grade. Keep repeated members traceable to their framing locations and schedule marks.
Connections and miscellaneous steel
List specified plates, bolts, anchors, stairs and rails separately. Identify connection design or detailing that remains a subcontractor responsibility.
Deck and joist boundaries
Measure deck areas and scheduled accessories. Clarify joists, bridging, edge angles and openings supplied by specialty vendors.
Coatings and erection
Separate shop primer, galvanizing, field touch-up and fire protection. Identify lifting, temporary stability and inspection scope from the project documents.
Measurement and scope checks
We reconcile plan member marks with schedules and sections, then calculate theoretical weight from the specified section weight and measured length. Connection material and miscellaneous assemblies are added on their own basis. Unissued connection details are not disguised as measured tonnage. For installed pricing, fabrication quotations, transport, crane planning and field labor remain separate inputs that the contractor can review against site access and sequence.
Illustrative member-weight calculation
Assume a fictional schedule contains twelve beams, each 30 feet long with a stated section weight of 22 pounds per foot. The example does not choose a structural member.
| Step | Calculation | Result |
|---|---|---|
| Total beam length | 12 × 30 ft | 360 LF |
| Theoretical member weight | 360 × 22 lb/ft | 7,920 lb |
| Short tons | 7,920 ÷ 2,000 | 3.96 short tons |
This is primary-member weight only. Connection plates, bolts, waste, coatings and miscellaneous steel are excluded. The shipping or purchased weight may differ from theoretical net weight.
Deliverable, pricing basis and quote
Request a member schedule and quantity workbook that identifies included steel categories, drawing references and unresolved connections. A priced return can distinguish supply, fabrication, transport and erection when the necessary inputs are available. Tell us whether the GC expects separate alternates or a fabrication-only bid. The written proposal defines the estimate’s boundaries, revision coverage, fee and delivery date.

Does the steel takeoff include connection engineering?
No engineering service is implied by the takeoff. We measure supplied details and identify items awaiting design or specialty-contractor definition. If a budget allowance is requested for unresolved connections, it should be explicitly labelled and agreed.
Can a single tonnage rate compare fabrication and erection bids?
It can conceal differences in scope. Member mix, connection complexity, coatings, access and field sequence may vary substantially. A useful comparison keeps these responsibilities visible rather than relying only on the quoted total per ton.
How are revised steel drawings handled?
Provide both issues and the revision register. Added or removed members, section substitutions and connection changes can be listed separately. Confirm whether the revision also changes deck, fireproofing, lifting or other dependent scopes.
