Land surveying: commission terrain records, setting out and boundary work
A survey for a garden project, construction setting out and a parcel subdivision need different information and responsibilities. Define the question to answer and who will use the results. This helps commission the work you actually need.
What result do you need?
Start with the purpose: record existing terrain, obtain levels for a design, set out construction or clarify a boundary. Every individual level does not necessarily need a complete terrain survey.
Setting out transfers agreed design points or lines to the site. This differs from recording existing conditions. For several construction stages, raise appointments and responsibilities in the enquiry.
| Task | Define the commission |
|---|---|
| Terrain survey | Areas, visible features and required drawings. |
| Level survey | Required heights and reference for later design. |
| Construction setting out | Design version, points or lines and stages. |
| Boundary question | Clarify the existing line or prepare a change. |
| Data processing | Check and prepare existing information. |
Describe the terrain and existing information
The work may cover a parcel, selected areas or several connected surfaces. Identify the areas and whether buildings, paths, retaining walls or other visible features should be recorded.
Existing drawings, earlier surveys and project drawings help define the task. Digitising an old drawing does not make it current. Clarify new measurements, additions or processing existing data only.
An approximately known terrain area helps initial discussions. You need not measure difficult areas yourself or supply technical coordinates for the enquiry. Missing information can be clarified with the professional.
Distinguish boundaries and official tasks
To make a boundary visible, subdivide or merge parcels, clarify the locally responsible cadastral office or qualified professional. A terrain plan for design does not replace these processes.
Changes can require further checks and registration. A proposed line or survey document alone does not mean a legally effective parcel change is complete. Ask about the entire process and parties involved.
Responsibilities for statutory lines and checks vary locally. Have the provider confirm the tasks they may perform and those requiring separate organisation. Do not move boundary markers yourself.
Agree reference levels, drawings and processing
Survey and design must work together for later use. Clarify the necessary position and height references with the designers and surveyor. Equipment names alone define neither the result nor its suitability.
A site plan, contours, sections, point list and processed terrain model are different deliverables. Agree content, format and useful detail. Recorded data do not automatically include finished drawings.
For volume comparisons, define the terrain or design states, survey dates and boundaries being compared. A calculated volume does not by itself settle a contractor billing dispute.
Coordinate access and construction
Describe known access times, closed areas, vegetation, steep terrain and live construction activity. The professional assesses survey feasibility and safe organisation. The enquiry requires no personal work on slopes or in traffic.
For setting out, coordinate the drawing version, contact person and next construction step. Agree who communicates changes and which markings are documented. Changes may require another visit.
Repeated checks or movement measurements are a distinct commission. A single terrain survey does not automatically include monitoring throughout construction.
Compare surveys with matching scope
Costs depend on the task, terrain, access, references and processing. Area alone is insufficient: one setting-out task, a processed terrain model and an official parcel change involve different work.
Compare fieldwork, processing, drawings and discussions. Agree approval of additional points, new design versions and further appointments. A short survey visit is not necessarily a complete service including processing.
Consider travel, expenses, VAT and any local official fees. Land-register or other third-party charges may be separate. Incomparable commissions cannot establish a reliable Swiss average.
| Cost item | Clarify in the quote |
|---|---|
| Preparation | Review existing information and coordinate. |
| Fieldwork | Areas, dates, access and reference points. |
| Processing | Drawings, levels, models or volume comparison. |
| Construction stages | Setting out, checks and changes. |
| Official tasks | Responsibilities and separate charges. |
| Total | Data handover, travel, expenses and VAT. |
Prepare a useful enquiry
Even without complete technical information, describe the purpose and known conditions.
- Purpose. Identify terrain recording, setting out, boundaries or data processing.
- Areas. Describe parcels, selected surfaces and required visible features.
- Information. Identify available drawings and the design stage.
- Organisation. Explain access, contacts and important construction stages.
- Deliverables. Clarify required documents and later users.
From your question to usable survey information
A clear commission connects purpose, local responsibility and agreed deliverables.
- Define the need. Describe areas, task and available information.
- Clarify responsibilities. Distinguish private recording and any official steps.
- Compare quotes. Compare matching services, dates, processing and charges.
- Coordinate work. Agree access, design version and visits with the parties.
- Receive results. Review coverage, references, open points and next steps.
Frequently asked questions
Is land surveying the same as a measured building survey?
Not entirely. Terrain, levels, setting out and boundaries differ from internal surveys and building drawings. Describe the areas and deliverables; define any combined commission expressly.
Can I survey part of the terrain only?
Yes. Identify areas and required content. The professional clarifies any additional reference points or neighbouring areas needed for a usable result.
Must I know coordinates or precise technical values?
No. Purpose, location and known documents are a useful starting point. Agree references, accuracy and processing with the professional according to intended use.
Can every provider change a parcel boundary?
Do not assume so. Clarify official tasks and responsibilities locally. A private drawing or survey proposal alone does not complete a legally effective parcel change.
What does land surveying cost?
Compare preparation, fieldwork, processing, appointments and data handover. Clarify travel, expenses, VAT and any official or land-register fees separately; different tasks do not have one uniform price per square metre.
Are all later construction checks included?
Only if agreed. A survey or setting-out appointment does not automatically include later checks, design changes or movement measurements. Record stages and extra visits in the commission.
