Checking for Movement
Precise Monitoring Surveys in Yorkshire and Beyond
What is a Monitoring Survey?
A monitoring survey involves the repeated measurement of fixed points to detect and quantify movement. These surveys are used to identify changes in position, level, or alignment, allowing potential issues to be identified early before they become costly or unsafe. The data collected provides clear evidence of whether movement is occurring, its magnitude, and whether it remains within acceptable limits.
Monitoring surveys can be carried out on:
Buildings and structures
Roads, bridges, and retaining walls
Excavations and earthworks
Railways and infrastructure
Slopes and embankments
What are Monitoring Campaigns in Surveying?
Monitoring campaigns in surveying refer to the process of periodically measuring and recording changes in the physical features of a piece of land over a
Why Monitoring Surveys Are Important
Monitoring surveys play a vital role in risk mitigation and asset protection.
Monitoring Surveys help to:
Detect movement early
Protect nearby buildings and infrastructure
Support compliance with planning conditions
Reduce the risk of structural damage
Provide defensible data for engineers and insurers
Support safe construction practices
Types of Monitoring Surveys We Provide
PAS 128 defines four survey categories, depending on the level of detail and verification required:
Structural Monitoring
Tracks movement in buildings, walls, bridges, and other structures during construction or excavation works.
Ground & Settlement Monitoring
Measures changes in ground levels, settlement, or heave caused by excavation, piling, or groundworks.
Crack & Deformation Monitoring
Monitors the development or widening of cracks within structures over time.
Pre-Construction Condition Surveys
Provides a baseline record of existing conditions before works commence, protecting all parties involved.
Tri-Tech Surveys will advise on the most appropriate PAS 128 survey type based on your project scope, risk level, and site conditions.
Monitoring Methods & Equipment
We use accurate, industry-standard surveying techniques, including:
Precise levelling surveys
Total station monitoring
Fixed control networks
Reflective targets and monitoring studs
Periodic or scheduled repeat surveys
Survey frequency and accuracy levels are agreed at the outset to ensure the monitoring programme meets engineering, planning, or contractual requirements.
Deliverables & Reporting
Our monitoring surveys are supported by clear, professional reporting:
Movement and displacement tables
Graphs showing trends over time
Annotated drawings and plans
CAD outputs where required
Clear commentary on results
Reports are designed to be easily understood by engineers, project managers, and stakeholders.

topographical surveys
Tri-Tech work for a variety of different clients on different projects, and we pride ourselves on delivering accurate, efficient, cost effective surveys ensuring our clients receive the best possible product.
utility mapping
Using the latest equipment, we can provide the location of underground services in either 2D or 3D. We use state of the art Ground Penetrating Radar and Electromagnetic Location to assist your project when service avoidance may be a potential issue on site.
monitoring
Is there any movement? That is the question that is asked before and during any monitoring scheme. That is the reason we undertake monitoring, to check for movement.
laser scanning
For mass collection of accurate survey data then nothing beats scanning. Using 3D laser Scanners the surveyors can capture millions of points per second with the creation of a PointCloud.
volumetric analysis
We specialise in the analysis of a scheme’s volumetrics at any point in time. Be it Tender, Prestart, Monthly, Weekly, or Final.
Bathymetric surveys
By using the latest surveying technology, we have been able to survey watercourses safely and efficiently.
setting out & site engineering
Bread and butter work for us! Having a strong relationship with many civil engineering companies we have a very strong team of Site Engineers and Engineering Surveyors working for us.
control network installation
At Tri-Tech we have vast experience in this field. Be it a large highway scheme or a private property we can advise on what accuracies are required from your control network depending on what work you are carrying out and the tolerances you are carrying this work out to.
uav mapping & aerial surveys
Large areas of ground can be covered capturing the most unbelievable detail which would just be unable to be recorded with traditional methods. Our clients have really seen the benefit of what UAV surveys bring to the table.
measured building surveys
Tri-Tech work for a variety of different clients on different projects, and we pride ourselves on delivering accurate, efficient, cost effective surveys ensuring our clients receive the best possible product.
3d machine control
Machine control systems have been around for years now and Tri-tech have been utilising these systems from the very start. We realised the benefits of these systems early on when working with earthworks contractors.
survey equipment hire
Being a leader in the Surveying and Engineering sector we have a fleet of modern survey equipment at our disposal which is second to none. We carry the latest GNSS Base Stations, GNSS Rovers, Robotic Total Stations, Laser Scanners, Digital Levels, and Dual Grade Lasers.
BIM Model Creation
BIM (Building Information Modelling) model creation in surveying refers to the process of using specialised software to create a 3D digital model of a building or infrastructure project that includes information about the project’s design, construction, and maintenance.
