Frequently Asked Questions
Q: Does my Hounslow basement need structural monitoring?
Yes — basement excavations, underpinning, and piling within 3m of neighbour's foundations require monitoring under the Party Wall Act.
Q: What accuracy is achieved?
±1mm using reflective targets and electronic distance measuring instruments.
Q: Who pays for monitoring in Hounslow?
The building owner typically pays all party wall costs — including both surveyors if there is a dispute.
Q: How do I commission a structural monitoring survey in Hounslow?
The standard approach is to brief the surveyor with the project address, the proposed works (basement, underpinning, piling, or party wall award), the trigger thresholds agreed with the adjoining owner's surveyor, the reading frequency (typically weekly during the bulk excavation phase, daily if the amber threshold is approached, fortnightly or monthly during the post-construction monitoring period), the monitoring duration (usually through the heavy works phase plus 3 monthly intervals after construction completes), and the deliverable format (a written report to the structural engineer and the party wall surveyor within 24 hours of each visit). icelabz drafts the monitoring scheme for inclusion with the planning application or the pre-commencement discharge-of-condition submission, and then delivers the monitoring on the programme. All icelabz structural monitoring in Hounslow is issued under the RICS Measured Surveys of Land, Buildings and Utilities standard (3rd edition) for downstream LPA sign-off, party wall award compliance, or building control use.
