Engineering, Detailing, BIM and Drafting Services
Multidiscipline project support for steel fabricators, contractors, EPC firms, architects and engineering consultants—covering structural steel, rebar, BIM, architecture, mechanical, piping, MEP and electrical documentation.
A Practical Service Structure for Design, Fabrication and Construction Teams
Structural Drafting Group provides specialist modeling, detailing, drafting and engineering-documentation support across structural, architectural, mechanical and building-services disciplines.
Projects can range from a single drawing package or model conversion to a complete steel-detailing, rebar, BIM, mechanical, piping or MEP coordination assignment. Services are configured around the client’s source information, software, standards, review process and intended downstream use.

Use the Services for a Single Package or a Connected Project Workflow
Clients may engage the team at different stages depending on the available design information, internal capability and project programme.
Quality Begins with the Correct Source Information and Responsibility Structure
Checking is organised around the intended use of the model, drawing, schedule or report rather than generic claims of perfect accuracy.
Scope and Source Review
Confirm current design documents, specifications, models, addenda, client standards, codes, responsibilities and deliverables.
Production and Discipline Check
Review geometry, dimensions, marks, schedules, notes, calculations supplied by others and discipline-specific requirements.
Interface and Coordination Check
Review architecture, structure, equipment, MEP systems, openings, embeds, supports, access and construction interfaces.
Issue and Revision Check
Verify comments, RFIs, approvals, file versions, drawing status, exports, transmittals, native files and archive records.
A Controlled Workflow across Every Service Discipline
The technical activities vary, but the underlying information-management and quality process remains consistent.
Scope and Input Review
Confirm source files, responsibilities, standards, deliverables, priorities and programme.
Project Setup and Planning
Establish software, templates, model structure, drawings, zones, packages and review gates.
Modeling, Detailing and Drafting
Develop the required models, drawings, schedules, quantities and supporting documents.
QA/QC and Client Coordination
Review technical information, interfaces, RFIs, comments, constructability and deliverable consistency.
Issue and Revision Support
Deliver agreed files and incorporate approved engineering, fabrication or construction changes.
Start with the Best Available Information and Define the Intended Deliverable Use
The source hierarchy and responsibility matrix should be agreed before production begins.
INTypical Source Inputs
Projects may begin with conceptual, design-development, tender, construction or existing-condition information.
OUTTypical Deliverables
Outputs are selected around engineering review, coordination, fabrication, construction, procurement or record use.
Tools Selected around the Project Discipline and Client Environment
The website’s current service content identifies Tekla, SDS2, AutoCAD, Revit, Advance Steel, SolidWorks and Navisworks among the company’s principal working platforms.
Confirm software version, templates, model structure, coordinates, catalogues, file naming, native-file needs and export formats before production. Software capability does not replace qualified professional review or approval.
