Service focus

Turn survey information into usable existing-condition models.

Nest helps organize point clouds, scans, photos, and old drawings into models and drawings your design team can use.

Problem

Existing conditions are hard to organize

Nest helps turn raw survey inputs into usable Revit or drawing information so design work can begin with more confidence.

Solution

Existing-condition modeling

Nest translates survey inputs into architectural BIM and as-built documentation with assumptions clearly noted.

What you receive

Existing-condition BIM and drawings

You receive model files, extracted drawings, PDFs, notes on uncertain areas, and organized files for renovation or due diligence work.

What we do

Point cloud and survey translation

Point-cloud and survey-to-Revit support for renovation, adaptive reuse, and existing building documentation.

01Point cloud to architectural BIMModel the agreed visible architectural elements from supplied registered scans, using confirmed units and coordinates.
02Existing conditions modelsDefine building areas, included elements, and modeling tolerances around the intended use of the model.
03As-built drawing extractionExtract the agreed plans, elevations, and sections from the model for your renovation or documentation team.
04Clear assumptions and tolerance notesIdentify coverage gaps and inferred conditions so your team knows what may require survey or site confirmation.

What to send

Start with the files you already have.

Send the files you already have. We will flag missing inputs before production begins so scope, deadline, and expectations stay clear.

FilesCurrent project materialPDF sets, DWG/Revit files, sketches, markups, scans, photos, references, and any existing drawings.
RulesYour standardsTitle blocks, templates, sample sheets, naming rules, software version, lineweights, and preferred output format.
GoalExpected outputTell us what should be delivered: CAD files, Revit model, renderings, PDFs, sheets, notes, or source files.

Existing building to usable model

Convert point clouds into existing-condition Revit models and drawings.

Your model is built from the supplied scan coverage. Nest records inferred elements and missing information, then returns the agreed model and extracted drawings for your renovation or due-diligence team.

How it works

How your Scan to BIM assignment is delivered.

You supply the brief and design direction. Nest confirms the scope, produces the work, and returns checked files with any questions that need your decision.

  1. 01Share the brief

    Share point clouds, survey files, photos, old drawings, scope boundaries, tolerance expectations, and model version.

  2. 02Agree the scope

    Confirm the deliverables, fee, software version, missing information, and review dates.

  3. 03Produce the work

    Reference the point cloud, model architectural elements, extract views, and document uncertain areas.

  4. 04Check the output

    Nest checks the work against the agreed brief and standards and flags unresolved questions.

  5. 05Return your files

    Receive model files, as-built drawings, PDFs, tolerance notes, and questions for field confirmation.

Software expertise

Work in the software your team already uses.

Tell us your software version, templates, required add-ins, and file format. We confirm compatibility before production so your team can open and edit the returned files.

FAQ

Common questions before sending files.

Can Nest match our standards?Yes. Send sample sheets, templates, linework standards, naming rules, and example deliverables.
Can we start small?Yes. Nest is designed for per-project support: one redline set, one model, one visualization package, or one deadline.
Who reviews the work?Production is managed and checked by architects before delivery.
Can you work in our Revit or CAD template?Yes. Share the correct software version, templates, title blocks, families, layers, and export requirements before kickoff.
Do you sign NDAs?Yes. NDA requirements can be handled before confidential drawings, models, or client information are shared.
How do revisions work?Revisions are tied to the agreed scope, marked comments, QA notes, and review dates so project managers keep control.
How fast can we start?We confirm current availability and a proposed start date after reviewing the task and source files. The start date is agreed in your proposal.
Do you replace licensed local architects?No. Nest provides production support under your studio direction and does not replace local code responsibility or licensed architect-of-record services.

Best fit

Renovation and existing-condition teams

Best for architects, survey teams, developers, and contractors working from point clouds, scans, survey files, photos, and old drawings.

A practical next step

What does your team need completed next?

Discuss your drawing, model, or rendering requirements. We will review the scope and confirm available support before you commit.
