Land surveying services include:
- Topographical surveys include measuring and recording the terrain, including roads, pylons, kerbs, service covers, boundary demarcations, fences and walls, with data available in both 2D and 3D formats – see below for further detail
- Engineering surveys for setting-out the delineation of buildings
- As-built surveys showing positions of structures and services
- GIS-compliant data capture for input to the Land Registry property register.
- Preparation of Land Registry compliant plans for planning applications, deeds, leases, acquisitions and disposals, and conveyancing.
- Boundary disputes — survey and advice on resolution. Delivering data to help settle boundary disputes, providing legal professionals with accurate information to make decisions.
- Drone surveys are an increasingly important tool for collecting large amounts of data quickly, cost-effectively and with minimal disruption, often in inaccessible locations.
Topographical
Topographical Surveys
Topographic Surveys involve the production of maps and plans which are true to scale. The maps are created to exactly represent details of both the natural and built environments. Topographical surveys can record the condition of buildings for conservation or historical records. It can detail surfaces & topography for engineering works and record the condition of projects at different stages making an accurate record of a building for quality control and certification purposes. The survey can establish floor, ceiling and window levels as well as producing plans, sections and elevations. Using equipment including GPS and Robotic Total Stations, Laser Scanners and Precise Digital Levels with on-board digital storage, Murphy Surveys UK can measure any feature of the built or natural environment swiftly and precisely and to the highest standard attainable. Outputs include 2D and 3D drawings, profiles and volumes, Autodesk Civil 3D surfaces, MX GENIO and LandXML outputs, 3D Modelling, 3D Animation Fly-through videos, 3D Visualisation and Building Information Modelling (BIM).Engineering
Engineering Surveying
We have a background in design engineering, contracting and civil engineering projects, giving us a detailed understanding of the survey needs and requirements of the design team. As experienced engineering surveyors, we have a proven record of providing accurate engineering surveys for use in design and construction of structural, infrastructure, transportation, environmental and civil engineering schemes.
We can provide accurate and reliable dimension data throughout the construction process from the base topographical survey, cross-sections and ground modelling information to cut and fill calculations, dimensional control to setting-out on-site and finished as-built drawings. The range of projects undertaken have also include more specialist engineering surveying such as railway projects, coastal erosions, tunnelling and restricted access site.

Boundary
Boundary Surveys
As qualified and experienced land surveyors we are constantly involved in every element of property boundaries and demarcations; whether it is positioning undefined boundaries or assisting in resolving boundary disputes between neighbouring owners.We are often instructed to act as an expert witness in boundary disputes and asked to provide the court with detailed boundary survey reports, evidence and statements to resolve ownership disagreements.
In addition to the conventional role of the land surveyors we also provide a file plan comparison service to compare existing site features, documented legal plans and site surveys to then liaise with HM Land Registry in order to resolve problems early in order to prevent boundary disputes occurring.

GPS
GPS Control
Survey Solutions are fully equipped with the latest survey quality GPS instruments and post processing software and can carry out all aspect of GPS surveying. We can collect precise static base-station observations to provide fully adjusted co-ordinated solutions for large scale mapping and major projects as well as undertaking real-time detailed surveys or setting-out using a local grid system or utilising the Ordnance Survey (OS) GPS Active Network.- OS GPS Active Network

Drone
Drone or UAV Surveys
Drone surveys, (also known as UAV surveys) have become an increasingly popular method of carrying out surveying projects.One of the major advantages of drone surveys is the versatility it offers your project. Suitable across a range of our services, drones are equally effective for both land and building surveys and offer an excellent option for inaccessible areas.
Another major benefit of a drone survey is the speed in which large areas can be surveyed. Capturing data can be quicker, safer and less intrusive than other means or in many cases, drones can be used as a complementary add-on service alongside more traditional surveying methods.
Data from drone surveys is available in both 2D and 3D formats with a range of additional options available. This could include point cloud data, ortho-rectified photography and fly over video footage, all ensuring you receive a high level of technical detail to support your project. Our drone team is fully compliant with the Civil Aviation Authority regulations for Remotely Piloted Aircraft Systems.
Drone surveys are ideal when working on projects such as quarries and landfill, traffic surveys, agricultural inspections, large scale mapping, and thermal imaging, as well as schemes where access may be restricted such as heritage projects and roof inspections.
Drones Overview
- Can capture data more quickly and more effectively than traditional methods
- Ideal solution for large land spaces and for inaccessible areas
- Suitable for a range of projects and schemes for both land and measured building surveys
- High level of technical data available including point clouds and flyovers
- Equally effective as a stand-alone survey or a complementary service
- Data available in a wide range of formats
- A safe and cost-efficient method minimising the amount of survey time on site
Monitoring
Monitoring Surveys
We undertake monitoring surveys to identify movement or deformation in any environment using precise digital levels, movement detectors, precision survey instruments and high accuracy reflectorless total stations. We can map small changes in vertical movement, level and horizontal movement or full 3D XYZ coordinate differences in either real-time or over long periods to demonstrate changes and trends.With a track record of designing, specifying, installing and completing job specific monitoring campaigns designed to accurately measure and record movement in a large variety of structures and buildings we are able to confidently advise and liaise with Clients and their Architects or Engineers to achieve the best monitoring system to meet their requirements.
From the settlement of buildings or the deformation of major civil structures to the movement of natural features and earthworks we can provide a detailed understanding of the dynamics and movement to the highest order of accuracy.
Monitoring projects have included; major bridges and structures, sea defence, soil embankment stability, historic buildings, steelwork, retaining walls and ground settlement at landfill site.

3D Laser
3D Laser Scanning
3D Laser Scanners or ScanStation are used for a wide range of High Definition Surveying HDS applications either alongside traditional survey instruments or as an alternative to Total Stations.Using 3D Laser Scanning instruments the surveyor can rapidly collect a large amount of accurate co-ordinated three dimensional 3D laser points from the surface of remote feature as a ‘point cloud’ image, providing rapid surveying solutions for inaccessible elements and complex geometrical detail.
When the 3D Scanner has scanned a structure or site to create a precise high definition survey image it is then processed with visualisation and modelling software to represent the surface surveyed. The data from the scanned image can then be used for a wide variety of applications including exporting to CAD in 2D or 3D models in wire frame or to other rendering software packages.
This type of surveying technology allows the surveyor to capture and use large volumes of 3D data in a range of environments and is well suited to measuring heritage sites, historic buildings and façades along with applications in detailed petrochemical and industrial environments. 3D Laser Scanners can also be used for surveying projects such as highways, tunnelling projects or hazardous sites where traditional survey instruments may not be appropriate.
