Our Services

Architectural Survey & As-Built Services

From measured building surveys to Scan to BIM workflows, our services cover the full as built lifecycle
for architectural projects.

As-Built Drawings
As-built drawings created from 3D laser scanning data

As-Built Drawings via 3D Laser Scanning

We capture your buildings with high-precision 3D laser scanning and convert point clouds into CAD and
Revit as built drawings. Floor plans, elevations and sections are delivered as accurate architectural
as built documentation.

Measured Building Survey
Professional land surveyors performing measured building survey

Professional Land Surveyors & Measured Building Surveys

Our land survey and measured building survey services provide reliable building measurement data for
architects, contractors and developers, supporting planning, design and construction decisions.

Digitisation
Digitisation of hand drawn plans to CAD and BIM models

Digitisation of Hand Drawn Plans to CAD/BIM

We convert legacy, hand drawn plans into clean CAD and BIM as built models. Ideal for firms modernising
archives into DWG, DXF or Revit formats.

Technical Documentation
Technical documentation and construction details for architects

Technical Documentation & Construction Details

We produce technical documentation and construction details that align with your design intent and
construction standards, including as built construction drawings for clarity and compliance.

Concept to Council
Concept design and council submission drawings

Concept Designs to Council Submission Drawings

From concept sketches to council-ready submission drawings, we help you develop coordinated documentation
that supports approvals and communicates your architectural design clearly.

3D Laser Scanning
3D laser scanning and LiDAR reality capture for architecture

3D Laser Scanning / Reality Capture

Our 3D LiDAR scanning services deliver detailed reality capture of existing structures, providing
point cloud surveys, point cloud to BIM and LiDAR scans to BIM models that reduce site visits and rework.

Our Process

How Our As-Built & Scan to BIM Workflow Works

From site capture to BIM-ready as-built models, our workflow is designed for architects, engineers
and surveyors who need reliable existing building information. Each step is optimised for accurate
as-built drawings, 3D laser scanning and Scan to BIM delivery.


1

Site Capture & 3D Laser Scanning

We visit site with high-accuracy 3D laser scanners to capture LiDAR point clouds of your existing
building. This forms the basis for precise as-built documentation, measured building surveys and
reality capture.

2

Point Cloud Registration & Cleaning

Multiple scan positions are registered into a single, accurate point cloud. We clean noise,
check alignment and prepare the data so that your Scan to BIM and CAD workflows start with a
trusted geometric reference.

Point Cloud Processing • Registration

3

Scan to BIM & As-Built Drawings

Our team develops BIM models and as-built plans directly from the point cloud. We create
Revit-based BIM models, CAD drawings, floor plans, elevations and sections aligned to your
project’s level of detail and documentation needs.

4

Quality Check & Delivery

We run QA checks against control points and design requirements, then deliver your as-built
documentation in the formats you need: DWG, RVT, IFC, E57 and point cloud files, ready to use
in architectural and engineering workflows.

FAQ

As-Built Drawings, Scan to BIM & 3D Laser Scanning – Common Questions

These answers cover how our as-built drawings, 3D laser scanning and Scan to BIM services work,
what you receive and how we support architects, engineers and surveyors on real projects.


What are as-built drawings and why are they important?

As-built drawings are accurate records of how a building actually exists on site, not just how it was
originally designed. They show real dimensions, positions of walls, openings, services and structural
elements. Architects and engineers rely on as-built documentation for renovations, extensions, tenant
fit-outs and compliance submissions, because it reduces surprises and design clashes later in the project.

What is Scan to BIM and how does it work?

Scan to BIM is the process of using 3D laser scanning or LiDAR to capture an existing building as a point
cloud, then modelling that geometry into a BIM environment such as Revit. We scan your site, register and
clean the point cloud, then build BIM models and as-built plans that you can use directly in your design
workflows.

How accurate are your 3D laser scans and as-built surveys?

Accuracy depends on the project requirements and access on site, but our 3D laser scanning workflows are
designed to achieve survey-grade results suitable for architectural and engineering design. We use control
points, registration checks and QA routines so that the as-built drawings and BIM models align with the
specified tolerances.

What file formats do you deliver for as-built drawings and BIM models?

We typically deliver CAD as-built drawings in DWG, and BIM models in RVT for Revit workflows. Where
required, we can also provide IFC models, registered point cloud files (E57, RCP/RCS or similar) and
supporting PDF plans for quick reference. Deliverables are agreed with you at the start of the project.

Do I need 3D laser scanning for every project, or can you work from existing plans?

If existing drawings are outdated, missing or incomplete, 3D laser scanning is usually the most reliable
way to capture the current condition of the building. In some cases we can digitise and update hand drawn
plans, then validate critical areas with targeted laser scans. We recommend the most efficient option based
on your scope, budget and risk profile.

How long does an as-built and Scan to BIM project typically take?

Timeframes depend on the size and complexity of the building, access constraints and level of detail
required. Smaller sites can sometimes be scanned and documented within a few working days, while larger,
multi-level buildings may require phased delivery. We always provide an estimated timeline with our as-built
and Scan to BIM quotations.
