Are Land Surveyors Accurate

Advanced Technology Offers Great Benefits

Technology, whether IT or the type of technology that benefits the building industry, for example, drives so many processes today.

Technology also advances as we speak, and new systems are constantly introduced to form the basis of the next generation of technologies to ensure that industries benefit in terms of greater accuracy, faster delivery and systems noted for their precision. The building industry is a perfect example.

When, in previous decades an owner of land – big or small, such as for one dwelling only – wanted to build, the professionals tasked with the project, such as the land surveyor, conducted their jobaccording to the demands of the time, which often involved slow, laborious methods when compared to what the building industry is offered today. For example, all information needed to assist with understanding the project in terms of land layout, of distances from borders, of placement of the building to be erected, of detail pertaining to walls, support beams, windows, and doors – and numerous examples of fine detail to ensure a complete project – had to be done manually, by hand.

Plans were drawn up using the traditional methods so the architect and engineer, and the builder, could go ahead and complete the project. These days those methods may be seen by many professionals as being antiquated, because they take so much longer and many mistakes in measuring and planning could lead to delays and sub-standard outcomes. Instead, modern, advanced technology dictates a different approach, an approach that uses technology such as 3D, which is no longer that new, and being used much more than ever before by the building industry for its notable features and qualities to speed up processes and to provide for accuracy and precision never experienced before.

The 3D model, which gives clients and all role players in a building project a perfect idea of what the completed product or project will look like, is the preferred method of recording the data necessary to create the model that clients, architects, engineers and builders want to study before building commences. Creating this model forms part of what is referred to in the industry as the so-called measured building survey, which includes all relevant data, creating floor plans, different elevations related to storeys and the different sections throughout the building to be erected.

All these processes are carried out by using the latest 3D scanning technology which is used to create the perfect 3D model for all parties to be able to look at and study. The 3D scanner is an advanced piece of equipment whose light beams record digitally every piece of the surfaces that form part of the project. This data, which is collected in a point cloud (millions of points form the so-called point cloud by being scanned via laser beam),is then analysed by leading software applications and perfectly clear 2D depictions created to show all relevant information to help the client and those working on the project to form a perfect idea of how the final project will look like before work commences.

This approach – as opposed to older methods – offers numerous benefits, such as spending much less time on site since the scanner collects all data which can then be analysed in the office, it saves time (and manpower and money, therefore) and it ensures that all information is recorded, and accurate measurements guaranteed.

The use of 3D has become the preferred method for most forward-thinking industries that rely on quality and accuracy as far as measured building surveys are concerned, but also in various other industries and applications, for example the world of medicine, the military and different forms of quality control, to name a few.

As an important addition to help further the processes of building and related industries, the 3D model has made its mark – and keeps on adding value for those industries that can benefit from its many features.

About Us

What is a measured building survey and when do you need it

A measured building survey is a precise depiction of your structure that includes all structural parts and architectural aspects. Floor plans are required to provide an accurate picture of the building, which is supported by elevations and cross-sections provided as scaled survey drawings.

By providing you with an accurate understanding of your structure, a measured building survey will help you prevent costly mistakes. Laser scanners are used by professional surveyors to precisely measure every element of your structure in 3D. You can always be certain that if you base your design work on their surveys, you will have all the information you need for a successful project.

Measured building surveys may be performed on a wide range of structures, including workplaces, schools, homes and historic structures and entail collecting accurate measurements of places or structures in order to create data that is then displayed at a reduced scale. They are often defined to an agreed-upon level of detail, as well as acceptable accuracy limits, costs, delivery timeframes, and scale.

It is also occasionally necessary for property renovation or when planning to enlarge a property. Measured surveys are particularly valuable for homeowners who need thorough information for a safety plan, as they capture internal floor plans, external and internal elevations, and a cross-section of the structure.

One of the most essential things you may ask an architect is if you need a measured survey. A measured building survey is usually performed for a number of reasons, but mostly to provide elevations and sections through a building, or to produce floor plans and these surveys are carried out by professional surveyors who use the most up-to-date 3D scanning technology.

Equipment

For measured building surveys, digital cameras with high resolution and infrared vision are particularly useful. They are used to take crisp and detailed photographs of a structure. The cameras used will frequently have built-in Wi-Fi, allowing photos to be rapidly transferred to a smartphone.

A laser tape measure is the electronic equivalent of a metal tape measure. To utilize a laser tape measure, the surveyor will position the instrument at one place on the structure and direct the beam to the second point of measurement.

When the beam strikes the second location, the sensors transmit the data to the calculating device linked to it. This method of measuring is quick, precise, and simple to apply, making it ideal for estimating the lengths of tall buildings, domes, or any other huge structure.

Surveyors can collect all the correct information they need in a very fast and cost-effective manner by utilising different cutting-edge tools, and this helps to prevent any human mistake that may have occurred with previous surveying methods. Their office software will then convert the data acquired in a point cloud into clear 2D renderings that include all important facts for your project, allowing them to create an exact image of the building.

When measured surveys are needed

Before beginning any structural work such as expansion or a loft conversion, you may require a measured survey to offer detailed and precise information on parts of your structure. They are not only used by contractors to price labour and supplies but also by designers to plan layouts and so on.

Some companies have years of experience delivering high quality measured building surveys in London and beyond.To perform even the most complex and demanding measured building survey projects, they employ millimetre accuracy equipment such as high accuracy total stations and laser scanners to gather data, as well as professional in-office technology and capabilities.

The cost of measured building surveys varies based on the size of the structure and the quality of surveying necessary, which is why a free estimate is an ideal way to begin the process. This service enables users to supply a measured building surveyor with all of the pertinent information they require to do an initial evaluation of the building in order to present the customer with the most competitive survey pricing.
