What are As-Built Drawing Services?

As-Built Drawing Services involve creating precise 2D and 3D documentation that reflects the true, final condition of a building after construction. At ViBIM, this is achieved by first developing an accurate 3D Revit model from high-resolution point cloud data, and then generating fully coordinated drawings like floor plans, elevations, and sections from that model. This ensures the drawings are an exact representation of the real-world structure.

As-Built Drawing Services

ViBIM delivers accurate and fully coordinated as-built drawings by modeling directly from point cloud data using Revit, ensuring consistency with real-world conditions. Our service guarantees precision, adherence to client standards, and seamless integration between 3D models and 2D documentation.

ViBIM specializes in delivering As-Built Drawing Services as part of our comprehensive Scan to BIM offering that serve the specific requirements of surveyors, architectural firms, general contractors and facility managers. Based on high-resolution point cloud data provided by clients, we develop accurate 3D Revit models that reflect real-world conditions, and from those models, generate precise and fully coordinated 2D as-built drawings, ensuring every detail aligns with verified spatial data and adheres strictly to both your project-specific standards and ViBIM’s rigorous internal quality protocols.
Our as-built drawing deliverables encompass complete architectural documentation for renovation, historic preservation, and existing construction projects, including detailed floor plans, building elevations, reflected ceiling plans, interior dimensions, and comprehensive MEP system layouts. All documentation is provided in multiple formats including CAD (.dwg), Revit (.rvt), and PDF to support diverse project workflows and client requirements.

Site and Topography Documentation

ViBIM provides comprehensive site as-built documentation that transforms point cloud data into detailed topographic models and 2D drawings of exterior environments surrounding buildings. Our services include modeling and documentation of sidewalks, curbs, driveways, internal roads, parking lots, courtyards, and landscaped areas directly adjacent to buildings, all featuring precise coordinates, boundary markers, and clear annotations.

Benefits of As-Built Drawing Services

As-built drawing services provide an indispensable, accurate record of a structure’s final ‘as-is’ state, which often differs from original design plans due to on-site modifications. This precise documentation is vital for successful future renovations, efficient facility management, and ensuring compliance, ultimately saving time and reducing costly errors.

The benefits of using As Built Drawing Services include:

Precise documentation based on laser-scanned data eliminates uncertainty and provides millimeter-level accuracy for confident decision-making throughout project planning and execution phases.
Seamless alignment between Building Information Models and 2D drawings ensures consistency and eliminates discrepancies that commonly occur with independent documentation development.
Unified documentation provides all project teams with consistent reference information, eliminating confusion and miscommunication from multiple, conflicting sources.
Accurate documentation prevents delays and cost increases that occur when actual conditions differ from documented assumptions during construction phases.
Comprehensive as-built drawings support maintenance planning, emergency response procedures, and operational decision-making throughout the building lifecycle.
Verified existing condition documentation facilitates code compliance verification and regulatory approval processes for renovation and modification projects.

The Industry Standards We Follow

As-built drawing standards can vary significantly depending on the client, region, or project type. ViBIM customizes all 2D outputs based on client-provided standards, ensuring technical clarity and consistency.

Our as-built drawing outputs can comply with standards related to:

Tagging and Annotation Systems: Labels for elements like doors, windows, and MEP components follow client rules or country standards (e.g., BS 1192, ISO 13567, US NCS).
Level Spot Elevations: These are derived directly from the point cloud-based Revit model and positioned according to drawing conventions.
Dimensioning and Measurement Rules: Dimensions are applied per client preference (center-to-center, edge-to-edge, etc.), ensuring real-world precision.
Line Weight and Layer Representation: Drawings follow specified line weights, colors, and linetypes for readability in print and digital formats.
Paper Size and Title Block Formatting: Layouts are customized (e.g., A1, A3 ISO sizes, ANSI D) including title blocks, sheet numbers, and legends.
Drawing Scales and View Organization: Plans, sections, and elevations use standardized scales (1:50, 1:100, etc.) with clear organization.

ViBIM ensures all drawings reflect real-world conditions and meet the visual and documentation standards expected for your as built drawing services.

Our As-Built Drawing Services Process

Revit Sheet Setup and Title Block Customization

Sheets are created in Revit using required paper sizes such as A1, A3, and ANSI formats, with title blocks customized to reflect the project name, client logo, project number, issue dates, and other metadata according to client standards.

View Template Configuration

Standardized view templates are developed and applied to control the visual appearance of drawings including line weights, hatch patterns, object visibility, and annotation styles that ensure consistency across all drawing types and scales. All view templates are tested and validated before application to ensure they produce the desired visual results.

Annotation, Tagging, and Parameter Setup

Tags for doors, windows, grids, levels, and other building elements, along with text notes and dimension styles, are configured based on client rules and local drafting standards to ensure accurate identification and measurement information throughout the drawing set.

View Placement and Drawing Composition

Required views including plans, sections, elevations, and details are generated and placed onto sheets with view scales adjusted appropriately such as 1:50, 1:100, and other standard scales, while view templates are applied to standardize appearance and maintain visual consistency.

Final Detailing and Quality Review

Once views are placed, our team meticulously adds final annotations, symbols, spot elevations, and any other client-requested details. This detailing stage includes rigorous verification of all dimensional information, ensuring annotation accuracy and overall visual consistency.

Concurrently, the sheets undergo a comprehensive internal quality assurance and quality control (QA/QC) review. This involves systematically checking all drawing elements against the source point cloud data and the 3D model to confirm accuracy. We also verify full compliance with client-specific standards and established industry best practices before any submission.

Thank you for your excellent work.

Best regards,”

Mr.Fran

“Hi Yen, Tung and Thanh

Thank you so much for your work on project

The model you have delivered is incredible!

I was just wondering how many hours you think it would take to model up some of the surrounding buildings in LOD 200

The purpose is to capture the elevations of some of the surrounding buildings that are facing our building project.

It wouldn’t need to be anything super detailed, just enough to capture the height of the buildings, their windows and openings and that sort of detail.

I know some of the data around these buildings are a little bit sparse so we understand that it may be difficult to model completely for some of the buildings

If you could let me know the hours it would take to model each building that would be great!”

Mr.Rad

“Hi Thanh,

Yes I have, there are more coming soon from this client in the next two weeks. Thank you for your excellent work on that project.

There are actually two other large jobs I need to get your assistance with both of which we have already won (pricing is for additional works so there is no bid process).

If I supply plans for Hospital projects tomorrow with photos would you be able to help in pricing these works? We met with the client today and am trying to get them free proposal next week. I apologise for the short notice, it is also short notice for us! Deliverables will be the same as those at lastest project that you priced previously.

I will send more info tomorrow.

Thank you”

Mr.Brode

“Overall, we are happy, and the turnaround times and communication have worked well for us. We do normally use Google Sheets to highlight any QA or general questions but didn’t have time to set everything up on these last projects. Saves us sending a folder with loads of screen grabs and allows your team to ask questions easier. Will look at setting up going forward.

As it stands, we are looking to be busy on the run up to the Christmas break so if any other projects land between now and then we will send over for some costs.”
