Fabrication Drawing Review Services — Independent Shop Drawing QA
We provide independent, rigorous quality control reviews of structural shop drawings and erection plans to eliminate fabrication errors before cutting begins.
What are fabrication drawing review services?
Fabrication drawing review services provide an independent quality assurance check on shop drawings and erection plans before steel cutting. Experienced checkers verify component dimensions, connection compliance, weld symbols, and design layouts, preventing expensive errors and constructability clashes in the shop and on-site.
Many structural failures and construction delays trace back to detailing errors that were not caught during the submittal phase. Total Engineering Consultants provides a dedicated, independent review service. We check piece marks, connection weld sizes, steel grades, and bolt specifications, providing fabricators with a verified drawing package.
REVIEW DELIVERABLES
Accuracy & Dimension Checks
Verifying every column height, beam length, bolt-hole spacing, and gusset plate detail against the engineer design sheets.
Constructability Audits
Identifying structural clearance clashes, field bolting access constraints, and site sequencing challenges.
Actionable PDF Markups
Providing clear, color-coded review markups and comment lists highlighting specific modifications for detailers.
AFC Approval Stamps
Stamping and certifying approved drawings as Approved for Construction (AFC), ready for immediate shop release.
OUR SHOP DRAWING REVIEW CHECKLIST
Coordinate Verification
Confirming that foundation layouts, anchor bolts, and grid coordinates match site conditions.
Connection Capacity Check
Verifying that connection plate thicknesses, weld sizes, and bolt counts meet engineer design loads.
Clearance & Fit Audits
Checking moment node zones, truss connections, and beam-column fits to prevent field interference.
Hardware & Spec Audits
Ensuring correct steel grades (A992, A36), bolt ratings (A325, A490), and AWS weld symbols are specified.
OUR DRAWING REVIEW WORKFLOW
We follow a systematic check process to review, mark up, and certify your fabrication drawing sets.
Drawing Submission

Design Alignment Audit
Verify that detail sheets match the EOR general notes, architectural plans, and grid layouts.
Geometry & Connection QA
Cross-check component lengths, plate details, weld preps, and structural spacing dimensions.
Constructability Check
Evaluate connection clearances, field wrench access, and structural lifting sequences.
Markup & AFC Stamp
Issue marked-up drawings to the designer or certify approved sheets with our AFC stamp.

DRAWING REVIEW FAQS
What are fabrication drawing review services?
Fabrication drawing review services provide an independent quality assurance check on shop drawings and erection plans before steel cutting. Experienced checkers verify component dimensions, connection compliance, weld symbols, and design layouts, preventing expensive errors and constructability clashes in the shop and on-site.
Why should I invest in an independent drawing review?
An external audit acts as a critical safety net. Even skilled detailers can overlook clearance conflicts or RFI modifications. Identifying a single dimension mismatch in the office prevents material scrappage and crane delays on site, saving thousands in overall costs.
What is the difference between a detailer check and a design review?
A detailer check is internal, verifying that sheets match the detailer's model. An independent review checks the drawing package against structural engineering designs, connection load requirements, OSHA site regulations, and spatial trades.
Do you stamp drawings as Approved for Construction (AFC)?
Yes. Once a drawing package passes our checks and matches structural specifications, we apply our quality stamp, certifying the drawings as Approved for Construction (AFC).
How do you perform the reviews?
We use a hybrid quality assurance workflow. We check 2D sheet sets details for scale and notations, and construct a simplified 3D overlay model in Tekla/Navisworks to double-check geometric clearances.
How long does a typical drawing review take?
We provide pricing quotes within 24 hours. A standard review of a 100-sheet package is completed and returned with marked-up files within 3 to 5 business days.
