Digital Construction

PQS Tech Solutions Logo

Digital Construction is the use of digital technologies and tools to manage, plan, design, and build construction projects.

It involves the integration of various digital technologies, such as Building Information Modelling (BIM), 3D modelling, virtual reality, and data analytics, to streamline and optimize the construction process. This allows for greater collaboration and communication amongst stakeholders, including architects, engineers, contractors, and owners, throughout the entire construction lifecycle. It can help to reduce errors, improve accuracy, and enhance efficiency, resulting in cost savings and better project outcomes.

Digital Construction has a range of possible applications, including project visualization, clash detection, scheduling, cost estimating, and facility management. It is a rapidly evolving field, and new digital tools and technologies are constantly being developed to improve the construction process.

Creating digital twins from surveyed Reality Capture information provides a highly accurate and detailed representation of the physical environment, whilst on the other hand, traditional surveying methods can be more cost-effective and efficient for smaller-scale projects or areas with limited accessibility. The choice between the two approaches will depend on the specific requirements of the project and the available resources.

Advantages of Traditional Surveying Methods:

  • Can be more cost-effective and efficient for small-scale projects or areas with limited accessibility
  • Requires less specialized equipment and expertise than Reality Capture technologies
  • Can be used to create a variety of deliverables, including maps, drawings, and models

Disadvantages Of Traditional Surveying Methods:

  • May not provide as much detail or accuracy as Reality Capture technologies
  • May be more time-consuming for larger-scale projects or complex environments
  • May require additional fieldwork to fill in gaps or inaccuracies in the data

Advantages of Reality Capture:

  • Highly accurate and detailed representation of the physical environment 
  • Provides a comprehensive view of the object or environment, including hidden or hard-to-reach areas
  • Can be used for a variety of applications, including simulation, visualization, and analysis
  • Allows for remote access and collaboration

Disadvantages of Reality Capture:

  • Can be expensive and time-consuming to capture and process the data
  • Requires specialized equipment and expertise to capture and process the data
  • May not be suitable for all applications, such as small-scale projects or areas with limited accessibility

Typically, Digital Twins are created using Reality Capture technologies, such as laser scanning, photogrammetry, or lidar. These technologies capture large amounts of data in a short period of time and provide highly accurate and detailed information about the physical environment. This data can then be processed using specialized software to either create or compare with a virtual 3D model of the desired object or environment.

The continued evolution of Reality Capture techniques and technologies has transformed surveying workflows by enabling mass data collection with a higher level of accuracy than traditional surveying techniques; this has enabled surveyors to provide a more complete picture of the physical environment in short periods of time.

Due to the detail and accuracy of the picture of the physical environment generated, there is a reduced need for interpretation by both the surveyors and their clients, minimizing the risk of errors or omissions. End clients and stakeholders can now visualize the physical environment in a more intuitive and immersive way, from multiple angles and perspectives, enabling them to make informed, critical decisions quickly.

The size and complexity of Reality Capture survey data can make it challenging to access and share with stakeholders who may be in different geographic locations. Fortunately, web portals are able to provide a convenient and efficient way to access and share Reality Capture survey data. At PQS Tech, we use web portals to make it easy for stakeholders to access Reality Capture survey data from anywhere, at any time, using only a web browser; eliminating the need to install specialized software or manage large files. Web portals provide a centralized location for Reality Capture survey data, which removes the need to send large files back and forth between stakeholders, reducing the risk of errors and data loss.

Our aim at PQS Tech is to better enable collaboration amongst stakeholders, allowing them to view and share data in real-time, promoting greater communication and collaboration and reducing the risk of misunderstandings and delays. One of our main priorities, as always, is to provide secure access to Reality Capture survey data, ensuring that only authorized stakeholders have access to the data, protecting sensitive data and ensuring that the data is not compromised.

This being said, traditional surveying methods, such as total stations, GPS, and manual measurements, are still widely used in many circumstances. These methods involve physically measuring and recording data about an object or environment, typically using specialized equipment and techniques. The data is then used to create a 2D or 3D map or drawing of the object or environment. These methods are often more cost-effective for smaller scale projects, and require less specialized equipment or expertise.

BIM Level 2 compliance is required for all centrally procured government projects in the UK since April 2016, the requirements are designed to promote collaboration, information management, and standardized information exchange among project stakeholders. The goal is to improve the efficiency and effectiveness of construction projects, while also reducing the risk of errors and delays.

Collaborative working amongst all project stakeholders, including architects, engineers, contractors, and suppliers, is needed to implement the BIM Level 2 compliance requirements. All stakeholders must work together to develop a shared understanding of the project goals, requirements, and risks. Developing a Common Data Environment (CDE) to manage all project information is required to attain BIM Level 2 compliance. The CDE is a single source of information for the project, which is accessible to all stakeholders, and must be structured to support the exchange of information throughout the project lifecycle.

BIM Level 2 requires the use of standard data formats and protocols for information exchange. This includes the use of open data standards, such as Industry Foundation Classes (IFC), and the use of standard naming conventions for files and objects. The use of this encourages the coordination of different models used in the project, in turn enabling us to check for clashes and conflicts between them, making it easier to resolve any issues before construction begins. BIM Level 2 also requires the development of a plan for the management of asset information throughout the project lifecycle. This includes the use of standardized asset data templates and the development of an asset information model (AIM) for the project.
