Workflow

Steel Detailing Process — Step-by-Step

Every project follows a structured workflow with QA/QC checkpoints at each stage.

01

Project Intake & Scope Review

Receive IFC/PDF drawings. Define scope, connection types, applicable codes (AISC, CISC, ASI, BS & EURO CODE). Assign lead engineer and confirm timeline.

02

3D BIM Modeling

Build accurate 3D model covering all members, connections, welds, bolts, and embeds per structural engineer's specifications.

03

IFA Drawing Production

Generate Shop & Erection drawings for Issued For Approval submission. Senior engineer QA review completed before delivery.

04

Client Review & RFI Resolution

Client marks up drawings. All RFIs resolved within agreed turnaround. Client approval gate before proceeding to IFC.

05

IFC / Final Submission

Issued For Construction drawings + NC/DXF files + Anchor Bolt Plans + Part Lists + BOMs delivered in agreed formats.

06

Post-Delivery Support

Field queries, change orders, and EOR coordination handled promptly through the entire fabrication phase.

Estimodeling Workflow

Quality Assurance

QC Process — 4-Stage Quality Control

Every deliverable passes through multiple QA/QC gates before client submission.

01

QA Stage 1 — Model Integrity Check

All member sizes verified against EOR drawings. Connection geometry and bolt spacing checked. Full 3D clash detection run on the model.

02

QA Stage 2 — Drawing Review

Cross-reference all dimensions against the model. Verify weld symbols, material callouts, and NISD, AISC, CISC, ASI, BS & EURO CODE annotation compliance throughout.

03

QA Stage 3 — Quantity Verification

Member count verified against drawing schedule. Hardware and bolt quantities cross-checked. Stock lengths confirmed against procurement requirements.

04

QA Stage 4 — Senior Engineer Sign-Off

Final review by engineer with 8+ years' experience. All RFIs cleared before delivery. Version-controlled file delivery with complete revision log.

100% QC compliant deliverables
Every drawing & report reviewed through all 4 stages

What Our Clients Say

Trusted by fabricators and contractors nationwide

"FSS's attention to detail is unmatched. Their shop drawings required zero redlines - that never happens in this industry. Will definitely use them again."

Sarah K.
Steel Fabricator, Ohio

"Their material takeoff service saved us over $12,000 on a school project. The accuracy of their quantity reports is incredible."

Mike R.

Frequently Asked Questions

Yes. All drawings are developed from IFC/approved design drawings and coordinated with architectural and MEP inputs. We run clash checks before issuing. Any ambiguity is raised as RFI before release.

Absolutely. All dimensions, levels, and orientations are clearly defined. No "by site" or missing values. Critical dimensions are double-checked, and general notes clarify any tolerances.

Yes. Every connection includes bolt diameter, grade (e.g., 8.8/10.9), hole type, and tightening requirement. Weld sizes, types, and symbols follow IS 800 or project-specific codes.

BOM is extracted directly from the 3D model, ensuring consistency with drawings. We run quantity checks and revision comparisons to eliminate mismatches.

We optimize wherever possible—standard plate sizes, minimal weld complexity, and practical cut lengths. However, we never compromise structural intent. Any optimization is discussed and approved.

Revisions are clearly clouded and tracked with revision numbers. We provide a revision summary and highlight affected parts only, so you don't have to recheck the entire drawing set.

Yes. CNC files are generated from the model and verified for compatibility. We ensure they align with machine requirements and match the latest revision drawings.

Yes. Member lengths are split based on transport limits and site handling capacity. Erection drawings include sequence, orientation, and match-marking for easy assembly.

Standard fabrication tolerances are followed per AISC or project specs. Critical fit-up areas (like base plates, splices) are dimensioned precisely to avoid site issues.

We maintain quick turnaround on RFIs—typically within 24 hours. Urgent shop queries are prioritized to avoid production delays, with direct coordination via email or call.
