3D scanning in Neuchâtel: secure building renovation with reliable plans

Renovating a building can quickly become a headache: difficult access, bad weather, old façades, irregular geometries, lack of up-to-date plans. The best way to save time (and avoid unpleasant surprises) is to use a 3D scan survey of the façade, roof and stairwell, in order to obtain precise plans and a solid basis for the energy renovation.

In this article, 3D Scan Bat explains how a 3D scan can help you move from an “uncertain” building to a “controlled” project, with deliverables that can be used directly by architects, engineers and contractors, saving you a lot of time and money.

A targeted 3D scan of the facade, roof and stairwell helps to secure a building renovation by capturing the actual geometry of the building. The scan provides reliable plans, reduces site contingencies and creates a precise basis for energy renovation, quantity surveying and coordination between architects and contractors.

Why scan a building before renovation?

Renovation (facade + roof + communal areas) is all about details: thickness, height, offsets, facade returns, openings, cornices, railings, stumps, technical emergences, etc. On an existing building, paper plans or old DWGs often no longer reflect reality. On an existing building, paper plans or old DWGs often no longer reflect reality.

A 3D scan brings :

  • Faithful capture of what exists (real geometry, including deformations)
  • A common basis of measurement for all stakeholders
  • Fewer return trips to the site, fewer reworks, fewer “site surprises”.”
  • Reliable façade plans for tenders, scaffolding and quantity surveys
  • Better preparation for energy renovation (envelope, thermal bridges, details)

Typical case of a 3D scan of a façade + roof + stairwell

If you wish: 

  1. Scan the façade

  2. Scan the roof

  3. Scan the stairwell (common areas)

  4. Obtain façade plans and a technical basis for energy renovation

It's an intelligent perimeter: we identify what has the biggest impact on costs, authorisations, the thermal envelope and site logistics. 3D Scan Bat is all you need.

1) 3D scan of the façade: the basis for plans and measurements

The facade survey produces :

  • Elevations (North/South/East/West facade)

  • Cuts (if necessary)

  • Identifying openings (windows, doors, window wells)

  • Details of cornices, balconies and frames

  • Unevenness (important for insulation, cladding and rendering)

As a result façade plans can be used for costing, tendering, prefabrication (depending on the solution) and scaffolding coordination.

2) 3D roof scan: avoiding costly mistakes

The roof is often the area where mistakes cost money: slopes, dormers, acroteria, gutters, stumps, ventilation outlets, future solar panels.

The roof scan is used to :

  • Measuring slopes and levels

  • Identify single points (junctions, upstands)

  • Preparing for energy renovation (insulation, waterproofing, ventilation)

  • Facilitate coordination with safety/access (lifelines, anchors)

3) 3D scan of the stairwell: safety, accessibility, interior renovation

Scanning the stairwell is useful for :

  • Renovation of common areas (cladding, railings, lighting)

  • Check templates (doors, landings, ceiling heights)

  • Study accessibility (right-of-way constraints, technical solutions)

  • Facilitate planning (internal scaffolding, protection, flow)

Obtaining reliable façade plans, This ensures that the costings and renovation work are accurate.

Yes, it's often the best cost/value ratio: you capture the areas that have the greatest impact on the envelope, safety and budget.

Yes, because it makes the geometry (surfaces, details, single points) more reliable and reduces the risk of “off-plan” solutions that cannot be implemented on site.

As a minimum : point cloud + façade plans. Depending on the project: sections, orthoimages and/or 3D/BIM model.

A targeted 3D survey = a simpler building site

For building renovation (facade + roof + stairwell), especially in winter, 3D scanning is a direct lever: less uncertainty, better plans, better coordination, and a solid basis for energy renovation.
