Frequently Asked Questions

Everything you need to know about our CAD drafting workflows, BIM standards, project turnaround schedules, and submittal deliverables.

Turnaround depends on project scope and sheet count. Standard residential permit drawings or single-trade 2D drafting sets typically take 3 to 5 business days. Larger commercial projects, comprehensive multi-discipline BIM models, or complete fabrication shop drawing sets are scheduled according to phased milestones, with weekly submittals and progress coordination meetings. We also offer expedited rush services for emergency bid deadlines.
We work natively in Autodesk AutoCAD (.dwg, .dxf), Autodesk Revit (.rvt, .rfa), Navisworks (.nwc, .nwd), Tekla Structures, Trimble SketchUp (.skp), and Civil 3D. We accept input materials in any formatβ€”including marked-up PDFs, CAD files, 3D laser point clouds (.rcp/.e57), hand sketches, and field photos. We deliver cleanly organized, uncorrupted, layer-standardized files formatted exactly for your firm's specific template requirements.
All projects include two complete rounds of revision markups at no additional cost. We work seamlessly with Bluebeam Revu, Autodesk Construction Cloud (ACC/BIM 360), or standard PDF redlines. Every delta is tracked with revision clouds, delta tags, and an itemized QA response log confirming how each redline was incorporated before final sign-off.
Yes, absolutely. Headquartered in Lilburn, Georgia, our technical leads strictly enforce compliance with the American Institute of Architects (AIA) CAD Layering Standards, the United States National CAD Standard (NCS), and applicable local building codes including the International Building Code (IBC) and International Residential Code (IRC).
Architectural design drawings establish design intent, aesthetics, and overall spatial relationships for permitting. In contrast, Shop Drawings are detailed fabrication and installation blueprints produced specifically for subcontractors, fabricators, and trades. They translate design intent into precise fabrication tolerances, weld symbols, fasteners, connection joints, and bill of materials (BOM) needed on the factory floor and job site.
We offer two transparent pricing structures: Fixed-Fee Per Project (ideal for defined permit sets, shop drawing packages, or specific modeling scopes where deliverables and milestones are pre-agreed) and Dedicated Resource / Hourly Retainers (ideal for architectural firms needing ongoing drafting capacity or flexible design-development support). Every quote is itemized with no hidden fees.
We execute BIM models from LOD 100 (conceptual massing), LOD 200 (approximate geometry), LOD 300 (precise architectural geometry and documentation), LOD 350 (construction and trade interface coordination), LOD 400 (fabrication-level shop detailing), up to LOD 500 (field-verified as-built condition).
We treat client confidentiality with the highest priority. All project files, proprietary design details, and client data are governed by our standard mutual Non-Disclosure Agreement (NDA). All data is stored on encrypted US-based servers with strict multi-factor authentication, and we never share or publish client drawings without explicit written consent.
