Modelling landscapes Ground modelling turns a topographical survey – with plotted levels and heights – into a 3D contoured or triangulated map. This provides a visual representation of the shape of the site measured. Before any work begins on site, an initial level survey of the area should be completed, in order to obtain accurate …
The finished article One of the aspects of our work that comes at the end of the construction project is an as-built survey. Also known as ‘as constructed’. This type of survey is usually produced when construction has been completed. They are used to illustrate where buildings, pavements, roads and other features have been built. …
What is drone surveying? The method of gathering data from an airborne vantage point is drone surveying. By using a high-resolution image, the photos can be stitched together. These images each carry a set of 3D coordinates, which enables further processing to assemble them into a sketch. Autonomous drone mapping is the use of a …
What does a land surveyor do? So you want to become a land surveyor? In all aspects of land or geospatial surveying, you will collect and analyse the data you capture to map what currently exists on a site. This information can be used in construction projects, on design drawings, for civil engineering projects or may …
The price of progress Surveying has evolved over centuries, but the basics of trigonometry, levels and points have remained constants in some form or another. They have been honed and developed, but the end results – such as the creation of new structures, the collection of data and the generation of topographical or underground surveys …
What is a Revit model? Revit is 3D building information modelling (BIM) software, widely used by architects, engineers, and contractors to create a digital single version of truth. This can then be used by all disciplines and trades throughout the project, to help complete their work. Revit was created to support BIM and not to …
Although some of our work is office based, or can be carried out remotely, our data gathering is carried out in-situ. Therefore, surveying is definitely an outdoor activity suited to people who like hiking in rugged terrain and who are used to working in extreme weather. We can literally be working in any location, from …
Interior designs When it comes to a new-build construction, a surveyor will be involved in every stage of the process. Having been on site from the planning stage, a surveyor may have carried out an initial topographical survey or underground utilities detection. This would have established the extent to which the site can be developed …
3D laser scanning can also be used for heritage surveys and conservation surveys, as well as volumetric surveys, where land/material mass can be calculated to create a desired outcome – for example, providing accurate areas of volumes for cut/fill balancing, or creating a mound or depression in the land to suit your design needs. What …
The Geospatial Commission was established in 2018 by the government as an expert committee responsible for setting the UK’s geospatial strategy and coordinating public sector geospatial activity. It is part of the Department for Science, Innovation and Technology, playing a crucial role to deliver improved public services, create new better-paid jobs and grow the economy. …
