​D1.5: Measuring and diagnosis solutions for inspecting building components


Deliverable D1.5 Measuring and diagnosis solution for inspecting building components is a follow-up of D1.4 Calculation and analytical methods for building components within the framework of WP1 and under the umbrella of T1.2 Self-inspection techniques and quantifying methods for building components. T1.2 ends at M45 and D1.2 is the final deliverable of this task. D1.5 is focusing on practical techniques using hardware and software tools for self-inspection of building components. D1.6 Calculation and analytical methods for MEP/HVAC components -the final deliverable in T1.3 is focusing on MEP/HVAC components instead of building components.

The techniques applying hardware at experts´ level are evaluated and demonstrated at the laboratory, at demonstration sites and at the Dragados factory. Exhaustive documentations about these results are available and embedded in deliverables D5.1 Lab test protocols and set-up, D5.2 Lab test report and recommendations, D5.3 Case study elaboration, field validation protocols, and equipment calibration, D5.4 Field validation report and recommendations, D5.5 Integrated field demonstration report and upcoming deliverable D5.7 Cross-case analysis and benchmarking. Furthermore the testing equipment applied has been enhanced in terms of handling quality by extending their functionality in WP2.

D1.5 is focusing now on the practical application of handling the test equipment and methodologies assigning thresholds and KPIs to them in order to rate qualities and balance them against INSITER demands. Especially enhanced 3D measurement systems, infrared non-destructive testing, and acoustic imaging technologies have been surveyed and the practical use in self-inspection activities has been elaborated and documented. The chapters of D1.5 are representing the explicitly applied technologies in the above mentioned fields of action:

  • 3D laser scanning
  • Thermal measurement
  • Air tightness
  • Acoustic measurement.

The structure of each chapter is following a systemic approach in order to ease the application: The objective is to simplify the retrieval of information by the applicant:

  • Devices and technologies
  • Applied KPIs
  • Procedure methodology and techniques
  • Thresholds.

In the framework of WP1 self-inspection techniques and process methodologies the closing deliverables D1.5 and D1.7 are embedded following the demands of the methodology related content and timing of measurements to be performed and the related calculation of KPIs. D1.4 Calculation and analytical methods for building components is focusing on quantification of results related to building components while D1.6 is focusing on qualification of building components related to their performance quality.

Nevertheless there is a holistic focus on a total building quality especially related to energy performance and consumption issues as elaborated at D1.5 and D1.7 at building component and MEP/HVAC component level.

The combination of the applied methodologies described in both deliverables insures the total building quality.

In the INSITER project, experiments were carried out with various testing technologies and equipment -laser scanner, thermal scanner, air tightness, acoustic measurement- at building sites in Cologne, in Pisa, Italy and Valladolid, Spain. These experiments gave the following results:

  • The crucial deviations being responsible for gaps and leakages at points of junction at building component level can be avoided by using enhanced measuring tools for dimensions and building physic performance;
  • The scan time can be shortened;
  • By using a linked tablet during the scanning, the results determine directly which parts should be scanned better;
  • In terms of 3D laser scanning different pointclouds from the same equipment indicate that some pointclouds can be more easily translated to BIM than others;
  • By using smaller parts, such as walls only, deviations between the BIM model and the pointclouds can be better mapped.
  • Air leakages can be detected before closing the building envelope by enhanced acoustic measurement.
