Construction and architecture

Because of the automation in processing of aerial imagery, recently acquired a broader scope of application, the UAV operation has become one of the modern trends in the current development of construction industry. A mini-UAV equipped with a camera and geodetic systems becomes a great tool to provide assistance in design and well-timed control over the subcontractor compliance with set up dates of construction.

Modern unmanned systems that have been deployed for the benefit of developer or constructor provide the cost and time-effective solution for the on-site monitoring of changes on the time-scale. Such operations enable further estimation of excavation volumes and rational use of resources to construct and develop the appropriate infrastructure and exercise the control over the traffic.

The data collected with the Supercam aircraft gives a valuable input to expose and identify hidden flaws and define the progress of positive and negative changes. Putting collected data on display is one of the essential elements in digital processing. Such data is what the digital terrain and elevation models are made of. Another product like Building Information Model gives a proper insight to define the exploitation costs with well-timed changes in coordination of design.

Carrying of the control calculations to prepare the comparative report that analyses the project specification and factual indices, largely define the peculiarities of the UAV application in the performance of the following operations:

• Aerial thermal imaging in the heat-loss assessment;
• Generation of accurate 3D elevation models in surface studies;
• Geodetic survey works with the UAV application (built-in survey);
• Accurate cartographic works with the critical assessment of specific terrain;
• Estimation of the excavation and embankment works to provide well-timed forecast on the construction development and completion, earthworks control;
• Supervision over the subcontractor compliance with construction deadlines;
• Wear and tear assessment of the control objects, the operational capability of the on-site machinery and control objects.
