As-Built CAD Drawing Services 2D Existing Condition Documentation from Survey Data
Accurate 2D AutoCAD drawings from site measurements and survey data. Floor plans, elevations, sections, and existing condition documentation — for property transactions, contractor handover, and record keeping.
What Are As-Built CAD Drawings?
As-built CAD drawings are 2D AutoCAD documents that show the exact existing condition of a building after construction or renovation. They document the real-world dimensions, layout, and features of a building as it actually exists — not as it was designed or intended.
Unlike design drawings that represent what was planned, as-built drawings record what was built. Every change, deviation, and field modification is captured and documented. The result is an accurate, reliable record of the building's current condition.
Where as-built CAD fits in:
- Existing condition documentation: Accurate records of what exists.
- Property transactions: Due diligence and survey support.
- Contractor handover: Documentation for building handover.
- Renovation planning: Reliable basis for design work.
"As-built drawings are the definitive record of a building's actual condition — essential for owners, facility managers, and future project teams."
Why Choose As-Built CAD Drawings?
Many buildings lack accurate existing condition documentation. Original drawings may have been lost, become inaccurate through multiple renovations, or never existed in the first place. As-built CAD drawings fill this gap, providing a reliable record of what exists.
Accurate existing condition documentation
As-built drawings give you confidence in your building records. You know what exists. You can plan with certainty.
Property transaction support
Accurate as-built documentation supports due diligence, valuations, and property transactions. Buyers and lenders need reliable information about what they are acquiring.
Contractor handover documentation
When you hand over a building to a contractor, they need accurate drawings. As-built documentation reduces RFIs and on-site surprises.
Renovation and maintenance planning
Renovation starts with knowing what exists. As-built drawings provide the basis for design, cost planning, and construction coordination.
Our As-Built CAD Drawing Process
We keep our process simple and effective. Accurate drawings delivered on time.
Site Measurement and Data Collection
We work from your site survey data. This could be:
• Site measurements. Our team or your surveyor visits the site.
• Marked-up drawings. Existing drawings updated with field changes.
• Site photos. Photographs capturing conditions and details.
If you do not have survey data, we can arrange the site measurement for you. Our network of survey partners covers most regions.
Redline Markup Review
We review all source data — marked-up drawings, measurements, site photos — to understand what needs to be documented. We flag any gaps or ambiguities before drafting begins.
CAD Drafting in AutoCAD
Your drawings are created in AutoCAD, reflecting the as-built conditions.
What we draft:
• Floor plans. Room layouts, walls, doors, windows, and finishes.
• Elevations. External and internal elevations showing building fabric.
• Sections. Building sections showing construction details and relationships.
• Reflected ceiling plans. Ceiling grids, lighting, and MEP elements.
• Site plans. Site boundaries, building footprints, and external elements.
Quality Assurance
Every drawing is checked for accuracy against the source data. Our QA process includes:
• Dimensional verification. Measurements checked against survey data.
• Layer standard review. Drawing layers verified against project requirements.
• Line weight and style audit. Consistent drawing presentation.
• Client review. We provide a PDF set for your review and feedback.

Frequently Asked Questions
As-built CAD drawings are 2D AutoCAD documents that show the exact existing condition of a building after construction or renovation. They document the real-world dimensions, layout, and features of a building as it actually exists.
Record drawings are prepared during construction and updated throughout the project. As-built drawings are prepared after construction is complete, documenting the final condition. As-built drawings are typically more accurate and comprehensive.
As-built CAD produces 2D DWG drawings from manual survey inputs. As-built BIM produces 3D Revit models from laser scan data. As-built CAD is faster and more cost-effective for documentation needs.
They include floor plans, elevations, sections, reflected ceiling plans, and site plans. They show building dimensions, layouts, finishes, and existing conditions.
They are created from site measurements, marked-up drawings, and site photos. Our drafters use AutoCAD to produce accurate 2D drawings reflecting existing conditions.
