A Party Wall Surveyor's Guide to Commissioning Monitoring Surveys
This guide helps party wall surveyors commission monitoring surveys that meet the requirements of the Party Wall etc. Act 1996 and provide the documented protection their clients need.
Why Party Wall Surveyors Commission Monitoring
Under the Party Wall Act, surveyors acting for neighbouring owners have rights to survey and monitor structures that may be affected by adjacent works. Monitoring surveys:
Document existing condition — Establish what the property looked like before works.
Track changes — Measure any movement that occurs during construction.
Support claims — Provide evidence if damage occurs.
Protect clients — Give neighbours the documented protection they are entitled to under the Act.
When to Commission Monitoring
Before Works Begin
Commission a baseline condition survey as soon as the party wall award is agreed. This establishes the pre-works condition and should be completed before any works commence.
During Construction
Commission ongoing monitoring throughout the construction phase. The frequency should reflect the risk level of the works.
After Completion
Commission a final monitoring survey after works complete to document any changes that occurred.
What to Include in the Brief
Location and Access
Site address — Full postal address.
Access details — Times when surveyors can access neighbouring property.
Contact name — Named contact for access arrangements.
Scope of Works
Description of works — Type of construction, depth of excavation, proximity to party walls.
Programme — Expected start and completion dates.
Contractor details — Name of building owner and contractor.
Survey Requirements
Type of monitoring — Baseline only, ongoing, or both.
Monitoring frequency — Weekly, fortnightly, or monthly visits.
Required deliverables — Report format, frequency, and distribution.
Trigger levels — Levels at which the monitoring surveyor should alert the party wall surveyor.
Adjacent Property Details
Number of properties — How many neighbouring properties need monitoring.
Type of construction — Age, construction type, and any known defects.
Existing cracks — Known cracks or movement that should be documented.
Selecting a Monitoring Surveyor
Experience
Choose surveyors with specific experience of party wall monitoring. They should understand the requirements of the Party Wall Act and the documentation standards required.
Response Time
For ongoing monitoring, choose a surveyor who can respond quickly to alerts. When trigger levels are reached, you need a fast response.
Reporting Format
Ensure the surveyor's reports are in a format suitable for potential dispute resolution. PDF reports with photographic evidence are the standard.
Professional Indemnity Insurance
Confirm the monitoring surveyor carries adequate PI insurance for the work.
Understanding the Monitoring Data
Baseline Report
The baseline report establishes what the property looked like before works began. Review it carefully and flag any discrepancies with the monitoring surveyor.
Ongoing Reports
Regular monitoring reports show whether movement is occurring. Key things to check:
- Any change from baseline
- Whether movement is increasing or stabilising
- Whether trigger levels are being approached
Alert Notifications
If an alert is received, act immediately:
- Notify the building owner's surveyor.
- Request an emergency site visit.
- Consider instructing legal advice.
- Document all communications.
Common Pitfalls
Commissioning Too Late
The most common mistake is commissioning monitoring after works have begun. The baseline must be established before works start.
Insufficient Scope
Don't just monitor the party wall — extend monitoring to all structures that could be affected by the works.
Ignoring Early Warnings
If monitoring data shows movement is occurring, act immediately. Early intervention prevents escalation.
Poor Documentation
Reports should include photographs, measurements, and clear analysis. Vague reports are useless in disputes.
Fee Guidelines
Monitoring survey fees depend on:
- Number of properties to monitor
- Frequency of visits
- Complexity of the structure
- Location
Typical fees for ongoing monitoring range from £200-500 per visit, with baseline surveys typically £500-1500 depending on property size.
