AS-BUILT DRAWINGS
As-built drafting service is one of our specialties which we provide with 100% accuracy, meeting the specific requirements of our client. Since our inception in 2007, we have been offering as-built drawings to general contractors, retailers, architects, homeowners, and builders. Advenser caters the demands for as-built services from clients all over the world from residential, offices, leisure, education, healthcare, commercial, and government sectors.

The final set of drawing forwarded to the client after the completion of the project is called as-built drawing. This drawing demonstrates the existing site conditions right after the installation or erection. We include all the modifications in the drawing that was made to the original construction. As-built drawing provided by us assists our client to compare the actual existing construction to the design stage condition.
Point Cloud to As-Built BIM Modeling
Advenser provides Point Cloud to As-Built BIM Modeling services that help architects, engineers, and construction professionals create precise digital replicas of existing buildings and infrastructure. By converting high-resolution point cloud data into intelligent 3D Revit BIM models, we support renovation, retrofit, and facility management workflows across a wide range of sectors.
Our LiDAR scanning specialists work with laser survey data, point cloud scans, or photogrammetry to develop as-built Revit models that accurately depict existing site conditions.
- Structural elements: walls, slabs, columns, beams, and roof systems
- MEP systems: HVAC ducts, plumbing, conduits, and cable trays
- Architectural features: openings, finishes, and ceiling plans
- Site context: topography, hardscapes, vegetation, and adjacent structures
Each model is created with a defined Level of Detail (LOD 300–LOD 500) and adheres to your company’s BIM standards and project requirements.
Our Scan to BIM services are widely used for:
- Building renovations and adaptive reuse
- Facility asset management and space planning
- Clash detection and coordination
- Construction documentation and verification
- Historical preservation and documentation of complex structures
We ensure deliverables are clean, clash-free, and compatible with major BIM coordination tools like Navisworks and Autodesk Construction Cloud.

Markups to As-Built/Model Drawing
Once the installation phase is complete, clients often provide redline markups reflecting field changes made during construction. Our team specializes in converting these markups into precise as-built drawings and BIM models that capture the true built conditions of the project.
Our experienced team of engineers and CAD professionals carefully interpret field annotations and incorporate every modification into updated drawings using industry-leading software such as Autodesk Revit, AutoCAD, AutoCAD MEP, and AutoCAD Architecture. Whether you need 2D as-built documentation or 3D models for coordination and facility management, we deliver accurate, code-compliant outputs in the format you need—DWG, PDF, RVT, or DGN.This ensures your records remain accurate and compliant for future renovations, facility management, or handover packages.
We utilize industry-standard tools such as Autodesk Revit, AutoCAD, AutoCAD MEP, and AutoCAD Architecture to deliver outputs tailored to client specifications and preferred formats (DWG, PDF, RVT, etc.).
What We Do
The documentation of as-built drawings generally takes place during or post-installation. In the midst of the construction process, workers may run into several unforeseen circumstances which require installing few items contrarily from the originally intended plan. These issues are generally tackled at the site itself and the new changes are marked in the plan or point cloud is forwarded to us, after installation.
Frequently Asked Questions
What are as-built drawings and why are they important?
As-built drawings are updated versions of construction drawings that reflect all on-site changes made during the building process. They are essential for project closeouts, renovations, facility management, and legal documentation. Accurate as-built documentation helps eliminate guesswork and ensures future modifications are based on reliable information.
What file formats do you deliver for as-built drawings?
We deliver as-built drawings in various formats including DWG, PDF, RVT (Revit), and DGN, depending on the project requirements. We ensure files are formatted according to your CAD standards and layering preferences.
Do you provide Scan to BIM services from point cloud data?
Yes. Our team specializes in Scan to BIM services, converting point cloud data from 3D laser scans into accurate as-built BIM models using Autodesk Revit. This is ideal for renovation, retrofit, or facility management projects that require a detailed digital twin of the existing structure.
Can you work from redline markups or hand-drawn sketches?
Absolutely. We offer Markup to As-Built drawing services by interpreting redline markups, field notes, or hand-drawn sketches and converting them into precise CAD or BIM documentation. This service is particularly useful post-installation or during change orders.
Which industries do you serve with as-built drafting services?
We provide as-built documentation for a wide range of industries including commercial buildings, industrial facilities, healthcare, education, transportation, hospitality, and infrastructure projects.
Do you handle large-scale or multi-location as-built projects?
Yes. With a scalable team and extensive experience, we can support multi-site rollouts, industrial plant documentation, or large commercial portfolios across regions, ensuring consistency in output and delivery.
How do I get started with your as-built drafting services?
