Choose the output around the design question
Floor plans show the layout at agreed levels. Sections cut through the building to explain heights, stairs, floors, and roofs. Elevations show its faces. A point cloud is a three dimensional collection of measured surface points; a model turns selected geometry into editable objects.
Imagine converting an attic into rooms. A floor outline alone may not show where the roof limits usable height. Sections through the roof and stairs could be more useful than adding detail to every room below.
Say which features need to appear
List what the design team needs: openings, columns, visible beams, floor levels, roof shape, or particular services. Identify the places where an exact fit matters, such as a new stair or a connection to an extension.
Existing buildings are not always straight or level. Agree whether the drawings or model will show those irregularities and where simplification is acceptable. A visually tidy model should not conceal a difference that affects the proposed work.
Make access and gaps visible
Arrange access to the relevant rooms, floors, external areas, and roof spaces. Explain restrictions and identify surfaces hidden behind furniture, finishes, or equipment. The survey can only record what the chosen methods can reach or see.
A measured wall outline does not reveal its hidden layers or prove that it carries loads. A service visible at both ends may follow an unknown route in between. The final information should distinguish observed geometry from assumptions and inaccessible areas.
Check how the files will be used
Agree units, floor names, the height reference, and whether the survey must align with a site plan or existing model. These details help different files work together without someone moving them by eye.
Ask for suitable accuracy requirements based on the project’s use. Drawing scale alone is not enough for digital data that can be enlarged indefinitely. Review a sample drawing or model to confirm the expected detail, labels, and file formats.
Choose the package with Geobiro
Geobiro offers surveying and laser scanning, measured CAD drawings, and BIM models. You can request fieldwork or provide point clouds from another survey team. Plans, sections, and elevations can be prepared in agreed drawing formats, including DWG and PDF.
Share the building location, purpose, required areas, access information, examples, and deadline. Geobiro can agree the survey or production scope with you. Include a record of survey dates and gaps. A measured survey documents geometry; condition assessment and structural advice are separate tasks.
Common questions
Do we need a BIM model?
Only if the team will use it for a defined purpose. Measured drawings and a suitable point cloud may meet the brief.
Can the survey tell us whether a wall can be removed?
It can document the wall and surrounding geometry. Its structural role and the consequences of removal need an engineer’s assessment and any necessary further investigation.
