Surveying & Data Capture

PQS Tech Solutions Logo

As technology has advanced, we too, have developed to remain at the forefront of technological development. Our surveys are no longer conducted using solely traditional equipment such as Dumpy Levels, Total Stations, and GNSS (GPS) receivers.

We now have a lot more tools in our arsenal.

From different types of LiDAR Laser Scanning equipment that can be terrestrial or mounted on UAV drones and Mobile Mapping Systems, to Remote Monitoring Systems that connect various types of equipment that can be accessed via a Cloud portal, we have all the technology and expertise to consistently and efficiently deliver high-quality surveys.

Whether it’s a small Topographical survey relating to boundary disputes or a large-scale survey for ongoing civil engineering projects, PQS Tech will always provide a precise and detailed mapping of the area with a wealth of information about the terrain, features, and characteristics of the land.

At PQS, maintaining our high professional standards is essential to our ethos; we strive to undertake surveying in the most accurate, safe, ethical, and compliant ways we can, which in turn has led to a strong reputation and continued success in the field.


Before beginning, the surveyor will review the project requirements such as the level of detail required, the expected accuracy, and any specific deliverables requested by the client.

At PQS Tech, we use a range of digital technologies including laser scanners, drones, and cameras, to collect data on the building. The data collected will depend on the project requirements but may include 2D plans, elevations and sections, as well as 3D models and point clouds.
Once collected, the data is processed using software such as CAD or other BIM systems to create a detailed digital model of the building. The model will be based on the survey data and will accurately represent the size, shape, and features of the building.

Before delivering the final product, our team will perform quality control checks to ensure the data is accurate and complete; this may involve cross-checking measurements and verifying that the model accurately represents the building.

At PQS, we pride ourselves on delivering a final product to our clients in a way that best suits their needs. This includes a range of deliverables, such as 2D plans, elevations and sections, as well as 3D models, point clouds, or BIM data. All deliverables are individually tailored to the needs of our clients and their project requirements.

In modern construction, the increased awareness of the environmental impact and the ever-rising economic costs involved in moving materials makes having accurate volumetric surveys, efficiently and safely undertaken, more important than ever. Good quality Volumetric Surveys are vital to providing up-to-date information about the exact amount of material required for a project, such as concrete, soil, gravel, or asphalt. This information helps contractors to plan and manage the material effectively, reducing wastage and optimizing the material usage.

The choice of surveying equipment and techniques used depends on the specific needs of the project and the environmental conditions of the site. Factors such as accuracy, speed, cost, and ease of use will be considered, but the safety of the surveyor along with everyone else on site is also paramount when selecting the most appropriate equipment dependent on job requirements. 


The Value Of As-Built Surveys

More and more the importance of good as-built surveys is growing, and not just upon project completion. At each construction phase, as-built surveys are typically conducted to provide an accurate record of the built environment at a specific point in time, usually at the end of the construction phase. Tracking the ongoing progress of work and running clash detection exercises before there is too much of a detrimental effect on timescales and budgets.

As-Built surveys are an ESSENTIAL part of construction projects, helping to ensure compliance with regulations, provide valuable records for future planning, and support legal and insurance processes.

The PQS Difference

Sometimes a simple drawing or written report is enough but when customers need more, PQS Tech leads the way in promoting new, innovative techniques for delivering as-built survey information to end users.  

The increasing use of Reality Capture (Laser Scanning, UAV Drones, Mobile Mapping, etc.) for surveying has brought with it issues with delivering information that we have never previously had as surveyors. Gone are the days of printing off multiple copies of drawings on reams of paper and trying to make the post office before it closes, the deadline threats have now changed to computer processing power and internet bandwidth.   

Embedded in our company DNA from the very beginning has been the idea of making the most of what technology is available in the modern world of construction and surveying to enable us to provide the best service possible. Due to the quick turnaround usually required for as-built surveys, most of the work we do is uploaded to the Cloud within a day of us being on site. We can offer access through a range of secure portals (Cintoo, Propeller, 3DM Cloud, etc.) depending on the requirements of the project and the needs of the customer.  

Alongside being a faster way to deliver as-built survey information, Cloud Portals take all the heavy lifting (the data sizes can be massive for Reality Capture) from the end users’ computer. Meaning end users don’t have to worry about getting specialist Desktop PCs with top-end graphics capabilities. The survey information can be viewed, interrogated and even manipulated and compared with BIM models on just about any device with an internet connection, from the more traditional, Laptop, to Smart Phones and Tablets, enabling the use of newer Augmented reality (AR) and Virtual reality (VR) interfaces

Advancements in digital technologies and the growing need for more efficient and accurate construction management have led to the emergence of automated construction progress tracking. Traditionally, construction progress tracking was a manual process requiring visits to site, physical measurements, and paper-based reporting. This approach was error-prone, time-consuming, and often resulted in delays and cost overruns. In recent years, digital technologies such as Building Information Modelling (BIM), drones, and sensors have become more affordable and accessible, making it possible to automate the process of construction progress tracking.

  • Availability of Data: With the increasing use of digital technologies on construction sites, there is an abundance of data available that can be collected and analysed to track construction progress. This includes data from BIM models, drones, sensors, and other sources. 
  • Big Data Analytics: The availability of large amounts of data has led to the development of big data analytics tools that can quickly process and analyse this data to provide real-time insights into construction progress.
  • Internet of Things (IoT): IoT technologies, such as sensors and connected devices, can be used to track equipment and material usage, monitor site conditions, and detect potential safety hazards, all of which contribute to automated construction progress tracking.
  • Artificial Intelligence (AI): AI technologies can be used to analyze construction progress data, predict potential delays, and make recommendations for improving efficiency. 
  • Cloud Computing: Cloud computing allows construction progress data to be stored and accessed from anywhere, providing real-time updates to project teams and stakeholders.
