What Is Structural Steel Estimating?
In structural steel construction, mill material costs, shop fabrication hours (cutting, drilling, fitting, welding), and field crane erection rates comprise major expense categories. Missing moment connection plates or miscalculating linear weight of W-shapes creates massive financial exposure.
At F&K Estimatings, our steel estimators use Tekla, SDS/2, and Bluebeam Revu to calculate linear feet and exact weight per foot from AISC shape databases, adding connection clip allowances, bolt schedules, weld lengths, and crane hook time.

Structural Steel Estimating Service Elements We Quantify
How Structural Steel Estimating Service Costs Are Calculated
Material and labor costs fluctuate drastically by project geography, supplier logistics, trade union jurisdictions, and site conditions. We do not use flat national averages.
Our cost database integrates regional material supplier pricing, union prevailing wage scales, open-shop labor rates, and local equipment rental benchmarks across all 50 U.S. states.
Raw Steel Mill Surcharges
Hot-rolled steel coil and scrap surcharges dictate base mill pricing per hundredweight (CWT).
Shop Complexity & Fabrication Hours
Heavy welded moment frames require 3x more shop labor hours per ton than simple shear-tab pin connections.
Crane Tonnage & Rigging Access
Large hydraulic crane rentals (150–300 ton) with long radius reaches significantly impact erection budgets.
Surface Preparation & Coatings
Hot-dip galvanizing and multi-coat epoxy systems add substantial per-ton finishing costs over standard shop primer.
Field Bolting vs Field Welding
Field-bolted connections are significantly faster and cheaper to erect than full-penetration field welds.
