// Main Steel Framing Systems

Precision detailing for columns, beams & bracings.

From multi-story framing to industrial complexes, we model and detail every member to your shop's welding, drilling, and handling preferences.

01. Heavy Members

Columns & Splices

Built-up columns, wide-flange columns (W-shapes), column splices, base plates, cap plates, and stiffeners coordinated with architectural grid lines and mill order tolerances.

  • Base plates & anchor bolt patterns
  • Field-bolted and field-welded column splices
  • Beam-to-column shear and moment connections
02. Floor & Roof Framing

Beams & Girders

Main floor beams, transfer girders, composite framing, and roof beams detailed with shop camber, copes, stiffeners, and shear stud locations.

  • Composite framing & headed shear stud layouts
  • Single-plate shear tabs & clip angles
  • Penetrations and reinforced web openings
03. Lateral Systems

Bracings & Trusses

Vertical bracing, horizontal wind bracing, chevron bracings, and cross bracings engineered with gusset plate geometry that optimizes shop shearing and field bolting.

  • HSS, angle, and wide flange bracing members
  • Gusset plate clearance & edge distance checks
  • Seismic-resistant detailing (AISC 341)
// Deck, Joists & Foundation Integration

Composite framing, joists, deck & anchor rods.

Anchor Rods & Base Plates
Setting plans locating anchor rods, leveling plates, and embed plates. Checked against structural foundation drawings and site benchmarks before the concrete pour.
Verified embed geometry
Composite Framing
Coordination of composite beam framing, shear stud pitch, concrete slab thickness, and pour stop angles for composite deck floors.
Zero clash with rebar
Open-Web Steel Joists
Coordination of joist girders, open-web K/LH/DLH steel joists, horizontal and diagonal bridging, and extended top chords with bearing seat requirements.
SJI / AISC alignment
Metal Deck Layouts
Corrugated metal floor and roof deck layouts, pour stops, edge angles, closure plates, and cellular deck openings mapped to structural steel.
Fast erection sequence
// Design Codes & Calculations

AISC, ASD & LRFD connection design.

Specification

AISC 360 & 303

Full adherence to the Code of Standard Practice for Steel Buildings and Bridges (AISC 303) and the Specification for Structural Steel Buildings (AISC 360).

Connection Design Methods

ASD & LRFD

Connection engineering provided under both Allowable Strength Design (ASD) and Load and Resistance Factor Design (LRFD) philosophies, stamped by registered P.E./S.E. engineers.

3D Modeling Software

SDS2 & Tekla LOD 400

High-fidelity 3D structural modeling with every clip angle, bolt hole, weld symbol, and clearance checked for fabrication and erection efficiency.

// Structural Detailing FAQs

Frequently asked questions about main steel detailing.

Q01 What deliverables are included in a structural steel package?
Every package includes comprehensive 3D erection plans (E-sheets), anchor rod setting plans, assembly shop drawings, single-part gather sheets, material cut lists, bolt lists, and direct CNC files (DSTV NC1, DXF, and KISS/FabSuite data).
Q02 How do you coordinate connection design with the fabricator?
We detail connections based on your shop's specific tooling preferences—such as favored bolt diameters, plate thicknesses, punch/drill capacities, and automated welding lines. We support both fabricator-provided design tables and full calculation submittals.
Q03 What is your typical turnaround for anchor rod plans?
Anchor rod plans and embed drawings are prioritized at project kickoff and are typically delivered within the first 5 to 7 business days so foundation pours are never delayed.
