How to Choose a Movement Monitoring Surveyor
To choose a movement monitoring surveyor, look for five key factors. The first factor is equipment (the surveyor should have modern digital levels for precise height measurement, biaxial tilt sensors for angular movement, manual or automated crack gauges for known existing cracks, and seismographs or geophones for vibration monitoring during construction). The second factor is reporting (the surveyor should provide weekly summary reports with same-day notification of any trigger exceedance, plus a final report at the end of the monitoring period for inclusion in the party wall award or for any subsequent insurance or dispute resolution). The third factor is turnaround (the surveyor should be able to mobilise to the site within five to ten working days of instruction, and the data reports should be issued within 48 hours of each monitoring visit). The fourth factor is experience (the surveyor should have direct experience of basement and deep excavation monitoring in the UK, with a track record of working alongside party wall surveyors and structural engineers on London projects). The fifth factor is insurance (the surveyor should have professional indemnity insurance covering movement monitoring, with the level of cover appropriate to the project value). icelabz provides movement monitoring surveyors across the UK and London, with the on-site installation of monitoring equipment typically scheduled within five to ten working days of instruction. The five monitoring services are settlement monitoring (vertical ground movement, typically with precise levelling), tilt monitoring (angular building movement, typically with biaxial tilt sensors on structural elements), crack monitoring (crack width change, typically with manual or automated caliper readings), vibration monitoring (construction peak particle velocity, typically to the thresholds defined in BS 7385), and level monitoring (ODN height changes, typically with optical or digital levelling). The cost bands are typical ranges for UK movement monitoring: per monitoring visit (295 to 495 pounds ex VAT) and monthly programme (1,500 to 3,000 pounds ex VAT). The typical monitoring period covers the construction phase of the adjacent works plus a defined lead-in and lead-out, often three to six months for a typical residential project. The alert/alarm/critical trigger convention is the standard approach, with values agreed in advance with the structural engineer. A signed accuracy statement is the QA evidence for downstream design, planning, and construction use, and all icelabz movement monitoring work is undertaken to the accuracy bands defined by the RICS Measured Surveys of Land, Buildings and Utilities standard (3rd edition).
