Structural Steel Detailing Services

Steel detailing is the off-site production of fabrication-level 3D steel models and shop drawings from structural design documents. It defines every member, connection, bolt, and weld, and outputs single-part and assembly drawings, erection plans, bills of material, and CNC data for the fabricator and erector.

Fabricators and erectors need drawings that leave no room for interpretation. Our steel detailing service turns your structural design drawings into a precise LOD 400/500 Tekla or Advance Steel model where every beam, column, brace, base plate, gusset, bolt, and weld is defined. From that model we extract single-part and assembly shop drawings, erection drawings, anchor bolt plans, bills of material, and NC1/DXF files that drive shop machinery without manual re-entry.

With 400+ delivered BIM/VDC projects for clients across the US, UK, and Europe, we detail to AISC, BS, and Eurocode standards and follow your fabricator connection standards, bolt assemblies, and drawing formats. We work in imperial by default and support metric, coordinate the steel model against architecture, structure, and MEP through BIM clash detection, and sign an NDA on request. Connection design remains with your engineer of record, and we detail from approved connection information.

Why Outsource Steel Detailing to Powerkh

Fabrication-ready accuracy

Members, connections, bolts, and welds are modeled at LOD 400/500, so shop drawings and CNC data go straight to the floor with minimal RFIs.

Code and standard compliance

We detail to AISC, BS, and Eurocode requirements and apply your fabricator connection standards and bolt assemblies from the first member.

Model-driven deliverables

Shop drawings, erection plans, bills of material, and NC files all derive from one Tekla model, staying consistent through every revision.

Flexible, predictable engagement

Hourly pricing with a free quote and payment only after delivery, plus an English-speaking team reachable 8:00-18:00 UTC+2 on weekdays.

Our Steel Detailing Services

Fabrication modeling

LOD 400/500 Tekla or Advance Steel models with every member, connection, plate, bolt, and weld defined for fabrication and erection.

Assembly and single-part drawings

Detailed shop drawings for each fabricated assembly and part, complete with dimensions, weld symbols, bolt lists, and part marks.

Erection drawings

Anchor bolt setting plans and erection drawings that show member locations, marks, and field connections for the erector on site.

Connection detailing

Modeling of shear, moment, and bracing connections from your engineer approved connection design and fabricator standards.

Bills of material and reports

Advance bills of material, bolt lists, and weight reports generated directly from the model for procurement and shop planning.

CNC and NC data

NC1, DSTV, and DXF files exported from the model to drive saws, drills, and plasma cutters without re-entering geometry.

Our Steel Detailing Process

  1. Share design drawings and standards

    Send structural drawings, connection design, and your fabricator standards with the target codes and formats. We review and return a free quote.

  2. Build the fabrication model

    We create the LOD 400/500 steel model in Tekla or Advance Steel, applying grids, member sizes, grades, and approved connections.

  3. Coordinate and check

    The steel model is clash-checked against architecture, structure, and MEP, and reviewed against design intent, codes, and fabricator standards.

  4. Produce drawings and data

    Assembly and single-part shop drawings, erection plans, bills of material, and NC/CNC files are extracted from the coordinated model.

  5. Approval, revisions, and delivery

    We issue drawings for approval, incorporate markups and revisions with updated cut lists, and deliver the final fabrication package.

Software We Use

We detail in the same steel fabrication and coordination tools your shop and erectors rely on.

FAQ

What is included in your steel detailing services?

A fabrication-level Tekla or Advance Steel model plus assembly and single-part shop drawings, erection and anchor bolt plans, bills of material, bolt and weld lists, and NC1/DXF CNC data - all detailed to AISC, BS, or Eurocode standards and your fabricator formats.

Do you design steel connections?

Connection design stays with your engineer of record. We detail connections from approved connection design and your fabricator standard connections, modeling every plate, bolt, and weld accurately for fabrication. We can flag issues we spot for the engineer to resolve.

Which codes and standards do you detail to?

We detail to AISC and US practice, British Standards, and Eurocode, and we apply your fabricator connection standards, bolt assemblies, part-mark conventions, and drawing templates so deliverables suit your specific shop and project requirements.

Can you provide CNC files for our shop machinery?

Yes. We export NC1, DSTV, and DXF files directly from the fabrication model to drive saws, drills, plasma and beam lines, so geometry does not have to be re-entered and shop throughput stays fast and accurate.

How do you price steel detailing projects?

We charge hourly and provide a free quote after reviewing your structural drawings, connection design, and tonnage, and payment is due only after the work is delivered. An NDA is available on request before you share any project files.
