Measured Building Survey: Get Accurate Surveys by Expert Surveyors!
A measured building survey is a detailed assessment of the dimensions and features of a property. It provides accurate measurements and data, which are essential for architectural design, renovations, or property valuations. These surveys are typically conducted by professional surveyors using advanced equipment and techniques.
Measured building surveys are a way for you to get an accurate representation of different building structures.
The primary goal of these surveys to take measurements of distinct structural and architectural elements of buildings.
Detailed surveys
The process requires professionalism, attention to detail, and, of course, specific equipment. Since measured surveys are considered an important property inspection method, we'll expand on some important considerations to bear in mind before instructing a company to carry out measured building surveys.
We'll start by tackling the most commonly asked questions, such as:
We'll also explain why you might need this survey, how much it costs inthe UK, and some potential issues that can happen along the way.
What Is a Measured Building Survey?
A measured building survey is a digital representation of a building. It can be carried out on a wide variety of different buildings such as: listed buildings, commercial properties, schools, offices, etc. For example, property buyers who want to do extensive research on their future building might require a measured building survey since it provides key information of structural elements. More precisely, the surveyor is provided with:
This gives them an accurate representation and layout of the building or premises.
Types of Measured Building Surveys
With the advancement in surveying equipment, building surveys can be classified into three main categories: unconnected, semi-connected, and connected building surveys. Let's see how these surveys differ from each other.
Unconnected Building Survey
An unconnected building survey relies on a simple method that does not involve one part of the survey being connected to the other - hence the term "unconnected." It centres around measurements on a room-by-room basis.
Semi-Connected Building Survey
A semi-connected building survey is an in-depth survey that concerns one ground floor, which is connected to all interior spaces and rooms. Afterwards, the verticality is assessed to match the other floor plan.
Connected Building Survey
A (fully) connected survey is when all parts of the building are connected by one control network. A range of survey equipment is used, one of which are laser scanners. And since this is a more detailed survey, it's practised when the emphasis is on accuracy and often includes internal and external elevations.
How Are Measured Building Surveys Delivered?
Measured building surveys can be delivered in the following
formats: 2D CAD drawings, 3D Revit models, IFC files, 3D BIM formats, Point Cloud, etc.
2D CAD Drawings
2D CAD drawings are a process that helps create and edit technical drawings. For the drafting process, computer-aided design (CAD) software is used. This helps develop precise floor plans, building inspections, landscape layouts and building permit drawings
3D Revit Models
3D Revit models are intended for a more comprehensive building survey. This is a process that helps oversee the entire building, which can be useful for all parties that participate in the construction process. These type of survey drawings facilitate 3D renders and walkthroughs.
What's the difference between 2D and 3D?
2D CAD drawings aim to show the surface's height and length, while 3D simultaneously provides detailed information about the objects' width, size, and depth. With 3D, it's much easier to incorporate information of other nature, such as costs or utility lines.
IFC Files
Industry Foundation Classes (IFC) and files is a platform that's used for editing any BIM software. This file format enables importing and exporting properties and building objects. This format facilitates communication, delivery time, and productivity throughout the project.
Point Cloud
Point cloud is now one of the most popular ways of delivering measured building surveys. It manipulates a huge amount of data, and gathering of that information can be gathered via laser sonar scanners. It's also one of the fastest measuring methods.
3D BIM Formats
Building Information Modelling (BIM) is a process that creates and edits different 3D, 4D, and 5D models that provide necessary information for building construction processes. It's meant for all types of building surveys, including towers, schools, properties, etc.
File formats for BIM include:
Necessary Equipment And Tools For A Measured Survey
Here are some of the traditional tools used for a measured survey.
Total Stations
Total stations can be used to measure distances and angles. This instrument combines electronic transit theodolite with electronic distance meters to give a precise layout of coordinates within a given space.
Laser Scanners
Surveyors often rely on HQ laser scanning as an accurate method of capturing detailed information about the space of existing buildings in 3D. Laser measure allows on-site surveyors to handle large amounts of 3D data and tailor it to their needs.
Automatic And Digital Survey Levels
Digital survey levels are considered a standard tool that's used in almost all survey drawings. The purpose of this tool in measured surveys is to help surveyors conduct advanced calculations on the site.
UAV - Aerial Drone Imaging
A UAV / Drone survey is used to oversee and accurately measure building surfaces. These surveys provide data by using downward facing sensors and are much quicker and more cost effective than traditional methods as well as being more accurate than using satellite imagery.
When Measured Building Surveys Are Needed
There are a number of applications where measured building surveys are useful:
The Advantages of a Measured Building Survey
Considering the variety of purposes for which building surveys are used, it' not surprising that there are many positive sides. Here are the most note-worthy benefits of measured building surveys:
Potential Problems That Can Occur
It's important to bear in mind that during measured building surveys, making mistakes is not out of the question. If the measured building survey is not accurately performed, this can lead to some costly mistakes on the surveyor's side.
Poor Design/Planning Permission Problems
The impact of sub standard design and incorrect or missing information can cause considerable issues with the project further down the line. Problems derived from incorrect building drawings can often result in a price jump during the project to rectify unforeseen issues along with end client frustrations.
Increased Costs
With the development of the project, incorrect measurements can cause a wide range of costly issues that were unplanned.
Delays
Incorrect plans, broken equipment and tools, lack of manpower - all these can cause delays in delivery time.
How Much Do Measured Building Surveys Cost?
For a properly conducted measured building survey in the UK, you can expect to pay from £1,400.
2D drawings and 3D BIM models are the most commonly requested ones among clients. For 2D graphics, you can expect to be charged upwards of£375, while 3D BIM models are more expensive and would generally start from around £550.
There are a few critical factors that can influence the price of a measured building survey:
The larger or more complex a property that needs to be surveyed, the measured survey cost will likely be higher. The same goes for the accessibility of the site.
Measured Survey FAQs
Measured survey architecture is used to create a detailed representation of a building which highlights the structural elements and features of the construction, including all walls, columns, beams and features such as doors and windows. This type of architectural survey provides developers and homeowners alike with detailed information for internal floor plans, external elevations and property records. These surveys can be delivered in a variety of formats, including 2D CAD drawings, Point Cloud, 3D Revit models and more.
This is a comprehensive survey which details floor levels and heights, with elevations and cross sections, to give a full overview of the building. Measured building surveys are essential in the architecture industry and are necessary for redevelopments and renovation projects, so that a thorough CAD plan can be created with safety, budget and accuracy in mind. For architects, being able to deliver designs to clients with accurate delivery times, acceptable tolerances and detailed costs, which measured surveys enable them to provide
One of the primary benefits of a measured survey for property owners is that it helps you avoid costly mistakes that can arise from inaccurate information or a lack of clear data. With a measured survey, you have a clear representation of a building, making it easier to create detailed CAD plans that are to scale, to budget and to deadline.
Measured surveys vary in detail, with basic surveys used to include elements such as windows, doors and walls, and complex surveys including the likes of plumbing, electrical layouts and more. Measured surveys can be used as the basis for electrical, plumbing and mechanical planning, as well as for planning permission for complex extensions or renovations where consent is required for building can begin.
Measured surveys are used by clients looking to redevelop their homes, or by developers in charge of construction projects. It simplifies the process, providing detailed data that can be used to plan new layouts, develop ideas based on room sizes and order materials in accurate quantities to minimise waste or overspending. They can be used for any type of building, from residential properties and flats, to warehouses, retail spaces, and listed or historic structures.
Whether you’re developing an existing property, adding an extension or starting from scratch and need to assess land, a measured survey can ease the process and provide more accurate, reliable results. They’re essential for developments but also for building restoration, providing useful information for architects and designers that helps to reduce wasted time and avoid potentially damaging or costly mistakes from occurring.
A measured survey is carried out by a qualified surveyor and requires an on-site assessment to capture the detail required by the client. This may involve various types of equipment, from drones to capture 4K video footage and 3D laser scanners, to GPS equipment, ground penetrating radars and more.
Accuracy is of paramount importance when it comes to this type of survey, which is why professional, experienced teams are required to carry out the work. Errors when capturing these details can have severe consequences, including disputes and disagreements, delays to schedules and unnecessary added expenses, not to mention safety issues with the build. For these reasons, it’s vital that trained, expert professionals are appointed to carry out measured surveys for reliable, detailed data capture.
