Services for Construction
“3D progress reports are essential for us now.
Digital Scanning Group provided accurate and cost-effective drawings, turned things around fast, and were always at the end of the phone when we needed them.
It’s made all the difference in keeping projects on track..”

Construction Projects Powered by 3D Technology
Modern construction projects demand more than drawings and assumptions. When programmes are tight and sites are complex, accurate digital information becomes critical.
We use advanced 3D reality capture technologies to record construction projects at every stage — creating reliable, measurable digital records that support design coordination, site management and long-term asset value.
Capturing Construction at Every Stage
From pre-construction through to handover, we digitally capture sites to reflect their true, as-built condition at a specific moment in time.
This includes:
Pre-works condition surveys
Progress capture during construction
Post-completion and handover documentation
Each capture creates a permanent, time-stamped record that can be revisited, measured and shared without returning to site.
Point Cloud Surveys
High-density laser scanning produces accurate point cloud data that forms the foundation of all downstream deliverables.
Point clouds allow project teams to:
Verify existing conditions
Detect clashes early
Measure with confidence
Coordinate design across disciplines
Once captured, the data can be reused repeatedly — reducing site visits and minimising disruption.
Gridlines & Datums
Accurate gridlines and datums are essential for successful setting-out, especially on refurbishment, retrofit and complex structural projects.
Using scanned data, we establish reliable control information that:
Aligns design intent with site reality
Reduces cumulative setting-out errors
Improves build accuracy across phases
This is particularly valuable where existing structures must be integrated with new works.
Revit & BIM Modelling
We convert point cloud data into accurate Revit and BIM models that reflect the real geometry of the building, not theoretical drawings.
These models are used to:
Coordinate architectural, structural and MEP designs
Reduce clashes and rework
Support off-site fabrication
Create reliable as-built records for asset management
The result is clearer coordination and fewer surprises during construction
Case Study: Commercial Office Building – London
Digital Progress Capture & As-Built Coordination
Project Overview
A large commercial office building in London underwent a phased refurbishment and upgrade programme while remaining partially operational. The project involved multiple contractors, tight access constraints and a requirement for clear progress reporting without increasing disruption on site.
Digital Scanning Group was appointed to provide regular 3D progress capture, accurate point cloud data and Revit modelling to support coordination, reporting and long-term asset records.
The Challenge
With multiple trades working concurrently and restricted access windows, the project team required a reliable way to:
Monitor progress remotely
Verify works completed at each stage
Coordinate design updates against site reality
Reduce the need for repeat site visits
Maintain a clear audit trail of construction activity
Traditional reporting methods alone were not providing sufficient visibility or accuracy.
Our Approach
We implemented a structured programme of 3D reality capture, aligned with key construction milestones.
At each agreed stage, the site was digitally captured using high-accuracy laser scanning, creating a time-stamped digital record of works completed.
From this data, we delivered:
Measurable point cloud datasets
Revit models reflecting current site conditions
Updated gridlines and datums where required
3D virtual tours for remote review and reporting
Each dataset was aligned to the project coordinate system, allowing direct comparison between design intent and site reality.
Progress Reporting in Practice
The 3D captures were used as a central reference point for progress reporting.
Project stakeholders could:
Visually confirm progress without attending site
Measure elements directly within the digital model
Identify discrepancies early
Review previous stages for clarification or verification
This proved particularly valuable during design coordination meetings, progress reviews and client reporting.
Revit Modelling & Coordination
Point cloud data was converted into accurate Revit models at key stages, providing the design team with reliable as-built information.
These models were used to:
Validate installations before subsequent works
Reduce clashes between trades
Support off-site fabrication decisions
Update asset information for handover
The use of live, accurate models significantly reduced uncertainty and rework.
Outcomes & Benefits
The use of 3D technology delivered clear, measurable benefits to the project:
Reduced site visits for consultants and stakeholders
Improved coordination across multiple contractors
Faster resolution of design queries
Clear, defensible progress records
A permanent digital record of the building’s transformation
By capturing reality at each stage, the project team maintained confidence and control throughout the programme.
Long-Term Value
Beyond construction, the final datasets now serve as a long-term digital asset, supporting facilities management, future refurbishments and lifecycle planning.
The project demonstrates how structured 3D progress capture can transform the way commercial buildings are delivered and managed — particularly in complex urban environments like London.
A Clear Advantage on Site
By combining 3D stage capture, point clouds, Revit modelling, gridlines and datums, we provide construction teams with a single source of truth.
The benefits are tangible:
Fewer site revisits
Better coordination
Reduced risk of disputes
Stronger protection against claims
Greater confidence at every project stage
When reality is captured accurately, decisions become faster, safer and defensible.
