What to Expect During a Measured Building Survey
Understanding the measured survey process helps you prepare effectively and know what to expect. This guide walks you through every stage from initial contact to receiving final drawings, explaining what happens at each step, how long things take, and how to ensure everything goes smoothly.
Whether you're a homeowner planning an extension or a developer managing a large project, knowing the survey process removes uncertainty and helps you plan accordingly.
Before the Survey: Getting Started
Step 1: Initial Contact and Enquiry
Contact surveying companies with your project details. Provide the property address, type of building, approximate size, and what you need (floor plans, elevations, sections, BIM model, etc.).
Good surveyors ask questions to understand requirements fully:
- What's the project? (Extension, renovation, planning application)
- Who will use the drawings? (Architect, engineer, planning authority)
- What level of detail needed? (Basic layout or comprehensive detail)
- What file formats? (AutoCAD, Revit, PDF)
- When do you need results?
Step 2: Quotation
Within 24-48 hours, you'll receive a detailed quotation outlining:
- Scope of work (what will be surveyed)
- Deliverables (plans, elevations, file formats)
- Timeline (site visit date, delivery date)
- Price (with breakdown if requested)
- Terms and conditions
Review quotations carefully, comparing not just price but what's included. Cheapest isn't always best value if scope is limited.
Step 3: Booking and Scheduling
Once you accept the quotation, the surveyor schedules your site visit. They'll need:
- Confirmation of site access arrangements
- Contact details for site representative if necessary
- Any access restrictions or special requirements
- Parking information if relevant
Most residential surveys book within 1-2 weeks. Urgent surveys often possible with 2-3 days notice.
Preparing for the Survey Visit
What You Need to Provide
Site Access: Ensure surveyors can access all areas requiring survey. For residential properties, someone should be present to let surveyors in and provide access to all rooms.
Clear Access: Remove unnecessary clutter where possible. Surveyors need to see walls, floors, ceilings, and architectural features. Furniture doesn't need removing, but better access helps.
Utilities Information: If service locations matter (meters, boilers, consumer units), have this information available.
Existing Plans: If you have previous drawings or plans, share these with surveyors. They're helpful references even if outdated.
What to Expect on Survey Day
Surveyors arrive with professional equipment:
- 3D Laser Scanners: Tripod-mounted devices capturing millions of points
- Tablets/Laptops: For scan registration and notes
- Safety Equipment: Hi-vis vests, safety boots
- Personal Protective Equipment: As required for site conditions
Professional surveyors are courteous, respectful of property, and minimize disruption.
During the Survey: The Process
Site Reconnaissance
Surveyors start with a walkthrough, understanding the building layout and identifying scan positions. They plan data capture strategically for complete coverage and efficiency.
Data Capture with 3D Laser Scanning
Modern measured surveys use 3D laser scanning for superior accuracy and speed. The process:
- Scanner Setup: Position scanner on tripod at strategic location
- Scan Execution: Scanner rotates 360°, capturing millions of points (2-5 minutes per scan)
- Move and Repeat: Reposition scanner, capturing next area with overlap
- Coverage Verification: Ensure all required areas captured adequately
For typical 3-bedroom house: 10-15 scan positions over 2-3 hours.
For larger properties: More scans, longer time proportionate to size.
Additional Measurements
Surveyors take supplementary measurements and notes:
- Verification measurements for quality control
- Details about materials and finishes
- Annotations about features or conditions
- Photographs for reference
External Surveys
If external elevations or site surveys included, surveyors work outside too. Weather-dependent activities may require flexibility with scheduling.
Minimal Disruption
Modern laser scanning is remarkably non-intrusive:
- Silent operation (no noise)
- No physical contact with building fabric
- No damage or marks left
- Furniture doesn't need moving (usually)
- Normal activities continue in other areas
You can work from home or go about business while surveying happens.
After the Survey: Processing and Delivery
Data Processing
Back in the office, surveyors process captured data:
Day 1-2: Scan Registration
- Individual scans aligned and registered together
- Creating unified point cloud of entire building
- Quality checks ensuring accuracy and completeness
Days 3-5: CAD Drawing Production
- Extracting floor plans from point cloud data
- Creating elevations and sections as specified
- Adding dimensions and annotations
- Organizing layers and formatting drawings
Day 5-6: Quality Control
- Senior surveyor reviews all drawings
- Checking accuracy against point cloud
- Verifying dimensions and consistency
- Ensuring professional standards met
Day 6-7: Final Preparation and Delivery
- Preparing files in specified formats
- Creating PDF packages
- Upload to secure file sharing
- Client notification of delivery
Typical Turnaround Times
- Small Residential: 5-7 working days
- Medium Properties: 7-10 working days
- Large/Complex Buildings: 10-15 working days
- Rush Service: 2-3 working days (premium cost)
What You'll Receive
Standard Deliverables:
- Floor plans of all levels (AutoCAD DWG format)
- External elevations (if specified)
- Cross sections (if specified)
- Site/location plan
- PDF versions of all drawings
- Organized file structure with clear naming
Optional Additional Deliverables:
- 3D BIM model (Revit format)
- Point cloud data files

Using Your Survey Drawings
Opening and Viewing Files
AutoCAD Files (.dwg): Require AutoCAD or compatible CAD software. If you don't have CAD software, many free viewers available (DWG TrueView from Autodesk).
PDF Files: Open in any PDF reader (Adobe Acrobat, web browsers). Useful for viewing, printing, and sharing but not for editing or measuring accurately.
Revit Files (.rvt): Require Autodesk Revit software or free Revit viewer.
Sharing with Your Team
Send survey files to architects, designers, engineers, and contractors. Everyone working from same base survey ensures coordination and consistency.
Keeping Files Safe
Back up survey files in multiple locations. They're valuable project documents you'll reference throughout design and construction. Consider these files essential project records worth protecting.
Common Questions and Concerns
Do I Need to Be Present?
For residential properties, someone should be present for access. For commercial buildings, site managers or facilities staff can facilitate access. You don't need to be there personally throughout the survey if access arranged.
Will Surveys Damage My Property?
No. Modern laser scanning is completely non-contact and non-destructive. No holes drilled, no marks made, no damage caused. Your property remains exactly as found.
Can Surveys Work Around Furniture?
Yes. Laser scanning works around furniture and belongings. Heavy furniture doesn't need moving. If possible, clear floor space helps surveyors move equipment, but not essential.
What If Rooms Are Locked?
Surveyors need access to all rooms requiring survey. Locked rooms can't be surveyed. Ensure all areas are accessible on survey day or advise surveyors in advance if some areas unavailable.
What Happens If Weather's Bad?
Internal surveys proceed regardless of weather. External surveys or site surveys may need rescheduling if weather prevents safe or accurate work. Surveyors contact you if weather impacts scheduling.
Can I Request Changes After Delivery?
Minor revisions or additional annotations usually accommodated within reason. Major changes or additional drawing types may incur additional charges. Discuss with your surveyor if requirements change.

- Poor Communication: Professionals respond promptly to questions
- Suspiciously Cheap: Below-market pricing suggests corners cut
Conclusion: A Straightforward Process
