Point Cloud to 3D Revit Model: From Onboarding to Delivering Excellence
At a Glance
Point cloud to BIM has revolutionized workflows for surveyors and surveying companies, making it indispensable to the AEC industry. By converting laser scans and photographs of as-built conditions into accurate 3D Revit models, it empowers stakeholders to visualize existing structures and make informed decisions with precision. Scan to BIM technology amplifies efficiency and reduces errors, transforming the way projects are executed.
This article provides an insightful walkthrough of one of our successfully accomplished Point cloud to Revit modeling projects, highlighting the crucial stages and challenges encountered, and the tools and techniques employed to overcome them. Join us as we explore the journey from project initiation to final deliverables.
Walkthrough of a successful Point Cloud to 3D Revit model conversion project
Picture this:
A leading chain of coffee outlets in the USA, a renovation roadmap, and the need for highly accurate 360-degree visualizations of 200+ running outlets. There was no way you could suspend operations of the coffee shops or control their customer rush. Point cloud to Revit modeling and meticulous digital reconstruction of the structures was the only way to know how to plan and carry out the renovations. That’s where we came in.
The client:
Our client was a leading surveying company offering survey, design and construction management services to a global clientele. They were well-versed in techniques and technicalities and used the latest equipment to capture as-built conditions, from scanners to in-house cameras to drones. They worked regularly with multiple point cloud conversion companies.

The first meeting
The initial meeting involved understanding and listening to the client’s unique needs, expectations, and the project outcomes they desired. Once the team of BIM experts at HitechDigital understood the business need, they defined the scope of work (SOW) & Level of Detail (LOD) requirement. Together with the client they agreed on the deliverable formats, the required building elements and non-geometric attributes.

Project assessment and documentation
Once the team defined and documented the scope of work, benchmarks against key project metrics including the permissible tolerances, deliverables, delivery schedules, reporting cadence and other control mechanisms were set. We also decided on communication channels and protocol. We agreed upon people who would act as dedicated points of contact (POCs) for the point cloud to 3D Revit modeling project. We created an in-depth project plan with timelines, roles and responsibilities and other details.
The client showed us photographs and scans of everything, but there were also gaps that had to be reconstructed by extrapolation. Our team of experts carefully understood the client requirements and made them aware of the data gaps that needed to be covered by engineering projections and validations.

Further understanding challenges
In the next two meetings we fine-tuned project scope and deliverables, including LOD, the tools to be used, the model and mesh parameters, documentation standards, file formats, project benchmarks and milestones. Most importantly, we agreed on project budgets and deadlines.
The primary challenges in the work that we discussed with the client included:
