Energy-efficient buildings real performance realisation and resolving the segmentation in construction:
- Integrated quality and performance assessment of building and MEP components; consolidated list of ‘most frequent errors’.
- Validation of as-built energy performance by BIM-based energy analysis.
- Method for estimating the final performance of the building taking into account the identified discrepancies / errors during construction.
Performance and quality assurance in construction industry:
- BIM, AR and software solutions for preventing errors during on-site construction / prefab assembly process: a) simulation of prefab assembly steps in parametric BIM; b) assembly manual in Augmented Reality (AR); c) self-instruction BIM-based process simulation and self-inspection based on embedded 3D thermal and acoustic checking; visualizing complex BIM models, planning and instrumentation data in AR; d) detailed BIM-based 3D AR scenes for architectural elements; e) detailed BIM-based 3D AR scenes for MEP/HVAC elements.
- INSITER Guidelines for new construction and refurbishment developed according to the 8-step methodology focusing on 9 EEB critical components with detailed content and real examples based on the demo cases. The content is accessible through desktop and mobile applications.
On-site inspection and building commissioning:
- BIM, AR and software solutions for controlling and ensuring the quality and performance during and after construction: a) on-site deployment of BIM: Real-time viewing the whole building and selecting building elements and properties; b) self-inspection of on-site prefab elements delivery: QR scan and product matching for logistic validation on-site; sending e-mail with QR and picture validation of the inspection – Prototype iPad app; c) self-instruction of the appropriate assembly procedure: Reviewing assembly manuals with description, pictures or videos – Prototype iPad app; d) self-inspection of the performed construction work: Checklist for technical inspection and validation – Prototype iPad app.
State-of-the-art ICT applications for on-site construction processes:
- AR solution for extensive and complex IFC BIM models for on-site self-inspection with referenced planning, self-instruction documentation and instrumentation data (deployed on tablets).
- Detailed self-instruction simulation and visualization (deployed on tablets, smart glasses, MS HoloLens).
- 3D laser, thermal and acoustic scan data from all real demo cases were integrated in the BIM models of the respective cases and visualised on desktop, mobile and AR applications.
3D scanning, detecting, sensing, measurement, positioning, imaging, and diagnostic equipment:
- Application of thermal camera for in-situ U-value estimation by Soft-Sensing approach (accuracy of about 2-4% higher than the accuracy of standard methods which is about 8%)
- Application of acoustic inspection techniques typically used in the automotive sector to the construction field (spatial leak detection in the order of 30 mm)
- 3D laser scanner for humidity assessment related to the change in the reflectivity index of moist surface.
- Tailored plug-in INSITER-DLL to combine 3D data with 2D imaging making it usable into BIM.
BIM that is accessible for all actors, and updated throughout the building’s lifecycle:
- Creation of accurate as-built BIM: setup general Model Guidelines, create Project specific Guidelines, create as-built model; verifying as-built model through 3D laser scan.
- BIM-based self-instruction models were created using the developed configurator software tool. Self-instruction guidance was visualised in Augmented Reality for real demo cases.
Trainings for self-inspection and use of advanced portable systems:
- Two training curricula and modules of workshop materials were developed: 1) Awareness training; and 2) Skill training. Some of the modules were also published as e-learning accessible through the synergy with the Build Up Skills programme.
