Precise documentation of existing buildings for renovation, remodeling, and facility management.
Arrival 3D delivers high-accuracy as-built documentation services powered by cutting-edge 3D laser scanning and LiDAR technology. We help architects, engineers, contractors, and facility managers capture existing building conditions with sub-inch precision—quickly and efficiently. Whether your project requires 2D CAD drawings, 3D BIM models, or a full digital twin, our scanning solutions reduce site revisits, minimize rework, and provide accurate data for smarter project planning and execution.
Why Accurate As-Built Documentation Matters
No construction project follows the original blueprint perfectly. Field modifications, rework, and undocumented changes often lead to discrepancies between the design plans and the completed structure. By the time a project is finished or a renovation is planned, these undocumented changes can cause costly delays and design conflicts.
As-built documentation delivers a reliable, up-to-date record of the structure’s actual layout—including architectural, structural, and MEP system components. With precise as-builts, your team can confidently plan expansions, renovations, or maintenance operations using verified, accurate data—reducing costly errors, delays, and surprises.
As built architectural drafting services involve the precise documentation of architectural elements
of a building to create as built model, floor plans, sections, and elevations for renovation,
remodeling, and facility management of the building. The architectural elements like walls, ceilings,
floors, doors, and windows are well documented in this service with an attention to detail.
Mechanical/HVAC, electrical, and plumbing services are the lifeline that keeps a facility functional.
These services require as built documentation for their operation and management. This can also
help identify any flaws in the services, which can subsequently be rectified.
Structural As-built construction drafting services document the load-bearing components of a
building including foundations, beams, columns, trusses, and other structural components.
Capturing accurate as built conditions of these elements is crucial for assessing structural stability.
As-built drawings are detailed plans that represent the actual, built condition of a structure or site at a specific point in time. Unlike original design drawings, which reflect intended layouts, as-builts document every change, adjustment, and modification made during construction. These drawings include accurate dimensions, material specifications, and the exact locations of architectural, structural, utility, and MEP (mechanical, electrical, plumbing) components.
Why As-Built Drawings Matter
Throughout the construction process, buildings often undergo changes—walls may shift, equipment might be relocated, and system layouts can evolve. As-built drawings provide a reliable record of these updates, ensuring that what’s on paper truly matches what’s in the field.
As-builts are essential for:
Renovations and retrofit projects
Permit applications and inspections
Future construction planning
Compliance with codes and regulations
When Are As-Builts Created?
As-builts can be recorded at various stages in a project’s lifecycle:
During construction to document real-time design changes
At project closeout by general contractors or subcontractors
Post-construction for documentation, handover, or renovation planning
Final versions are often referred to as record as-builts or for-record drawings.

Geospatial Data Collection
Capturing an as-built involves documenting the actual, built condition of a structure as it exists—after construction, renovation, or modifications have taken place. At Arrival 3D, we use advanced 3D laser scanning technology to ensure every architectural, structural, and MEP element is accurately recorded with sub-inch precision.
1. Site Preparation & Planning
We begin by defining the project scope, identifying key areas to scan, and confirming deliverable formats (e.g., 2D drawings, BIM models, digital twins). Coordination with your project team ensures minimal disruption during scanning.
2. 3D Laser Scanning On-Site
Using terrestrial laser scanners like the Leica RTC360 and NavVis VLX, our technicians capture millions of spatial data points in minutes. These devices document everything—walls, ceilings, mechanical systems, utilities, and more—with extreme accuracy.
3. Point Cloud Registration
All scans are aligned and registered into a unified 3D point cloud, which becomes the foundation for creating accurate models and drawings.
4. Data Conversion & Modeling
We convert the point cloud into your requested deliverables, including:
2D CAD Drawings (DWG, DXF)
3D Revit BIM Models (LOD 100–500)
PDF Plans and Elevations
Digital Twins for long-term facility use
5. QA/QC Review & Delivery
Each deliverable goes through a detailed quality control process to ensure it meets your accuracy requirements and project standards.
As-built drawings are critical for a wide range of professionals involved in the planning, execution, and maintenance of construction projects. They provide an accurate, real-world record of what has been built—helping reduce risk, ensure compliance, and support long-term decision-making.
Key Users of As-Builts in Construction:
