Jambo House

Now: marked-plan outlines and zones are retained. Exact building, level, scale and extent are unconfirmed.

Add: current marked plan, sheet/revision, room or level names, and known dimensions. Confirm Z01 general scope, Z02 bridge floor and Z03 lighting only.

Now: floor/bridge outlines and visible structural or architectural study objects exist; dimensions and levels remain estimates.

Before a scan: use supplied dimensioned floor plans, elevations and sections to reconstruct supported boundaries, openings, levels and interfaces. Compare the plan to the existing model before changing it.

Verify: dimensions and current changes using independent trusted records or targeted field checks. Do not invent unseen rooms or structure.

Now: visible ceiling and pendant studies, plus a model-derived reflected ceiling plan. Fixture count, positions and heights need confirmation.

Add: ceiling plans/sections, fixture schedule, photographs and height references. IES files and actual fixture data are needed for a full photometric study.

Verify: actual inventory, suspension heights, interfaces and changed conditions. Concealed services stay unknown until supported by evidence.

List the required elements and properties, permitted approximations, dimensional tolerances, intended use, exclusions and reviewer. Use the agreed specification edition. No default tolerance is assumed here.

Reliable plans can support the base model before scanning. A scan is one verification source, not a requirement for every BIM model. Use it where current conditions or evidence gaps require capture.

Now: study IFC and model-derived drawings are available. Geometry remains preliminary.

Check: import the IFC, save and reopen the RVT, compare units, geometry, categories, quantities and drawings against the approved scope. Imported solids may need native-family authoring.

Create the Revit study

Record the source revision, independent checks, remaining gaps, reviewer and acceptance date for each required element. Keep the old model for rollback. Better visuals, extra triangles and file conversion do not count as acceptance.

Detailed requirement record

Current Jambo acceptance: zero regions accepted at LOD 250. No green acceptance is inferred from visual realism, mesh detail or a successful file conversion.

Open Check model in the viewer to inspect a represented part and its field task. The crew can supply usable plans or targeted observations. Human review must bind the result to the source/model revision and the agreed tolerance.

“I need an LOD 250 BIM model of this area.” Mark a drawing, select elements or define a limit box. Add plans, photos, dimensions or corrections to improve the source record.

1. Check the available data. Identify the requested area, source coverage, required elements, accuracy and deliverables.
2. Use it or fill the gap. Where suitable scan coverage exists, scope the requested extraction. Where scan coverage is missing, prepare a capture bid for that area with access, accuracy, deliverables and deadline. Reliable plans and imagery can support modeling while capture is arranged.
3. Review the result. Check returned data, propose model changes and release an accepted revision after human QC. Keep sources and earlier revisions.

Workflow to implement. Private file intake is available through Add files. Mapping, voice requests, coverage-to-bid routing and end-to-end extraction still require review or further integration. A request starts scoping; it does not certify LOD or accuracy. No bid is issued and no charge is made here. Private inputs require authorized project access.

How it connects

Plans & sections → the base. Dimensioned drawings can establish shapes, levels, openings and scope. Check the revision and site match first.

Photos → visible detail. Photos help identify ceiling patterns, fixtures, materials and changes. One image does not prove depth, dimensions or hidden conditions.

Scale & requirements. A known dimension can constrain a matching photo feature; more views are needed to resolve depth and perspective. A typical door size is not a measurement. Applicable code and project requirements are checks to meet, not proof of existing dimensions.

Photos → a realistic walkthrough. NeRF learns how a place looks from overlapping views. Gaussian splatting uses many small 3D shapes to show those views efficiently. Photogrammetry can recover camera positions and candidate surface geometry. These methods complement the BIM model.

Next step: add original overlapping photos or a steady video walk, covering the same area from several positions. Keep the scene stable and include a known dimension plus independent check dimensions. GO3D must confirm camera alignment, coverage and scale before accepting reconstructed geometry.

Current status: no accepted photo-camera alignment or trained NeRF/splat for this project. A convincing view does not certify dimensions, hidden systems or LOD 250. Scans can verify and update the base later.

NeRF: original research and examples · Gaussian splatting: research and examples

Scans & measurements → verification and updates. Compare the base model with actual geometry, fill missing coverage and record what changed. Capture method and independent checks determine usable accuracy.

Schedules & specifications → the right properties. Fixture IDs and IES files support lighting analysis; model requirements define what to include.

Example: a pendant photo suggests visible form; a lighting schedule identifies the fixture; a section constrains its height; a field check verifies its current position. Keep each source attached to the proposed element.

Photo matching record · Architect photo reference

6 licensed views tested. Two promising photo pairs. The 2017 ceiling pair produced 475 reciprocal matches; the 2015 pendant pair produced 911. Tests on points left out of fitting support these local pairs.

Still unverified: the pairs do not join into one reliable scene. Assumed camera settings change the candidate geometry. Scale, scope and LOD 250 acceptance remain unconfirmed.

View photo matches · Trial details

The earlier two-photo trial is preserved in the source record. Neither trial changes the BIM geometry or establishes metric accuracy.

Jambo lobby and bridge gallery — fixed timber, railing and light details; capture dates unknown. Source links only.

Disney’s lobby article and social video — article dated April 6, 2023; video access unverified.

2005 photo set excluded. Four additional licensed previews show suite-like interiors and a balcony, with no confirmed match to the marked lobby. They were not added to the model. Review source decisions.

TripAdvisor, Yelp and Google galleries were not used for reconstruction: access or reuse permission remains unresolved. No guest details were added. None of these references establishes the marked scope, scale or current condition.
