Summary
This summary is machine-generated.This study introduces a hybrid Scan-to-BIM workflow using terrestrial laser scanning (TLS) and unmanned aerial vehicle (UAV) photogrammetry. Predictive planning significantly improved documentation completeness and reliability for complex structures.
Area Of Science
- Geomatics Engineering
- Digital Heritage Documentation
- Construction Informatics
Background
- Incomplete survey data compromises Building Information Models (BIM) reliability, especially for complex or restricted-access structures.
- Traditional Scan-to-BIM workflows face challenges with occlusions and limited site accessibility, impacting data completeness.
Purpose Of The Study
- To develop and validate a hybrid Scan-to-BIM workflow integrating TLS and UAV photogrammetry.
- To introduce a Predictive Scan Feasibility Estimation Model (PSFEM) for optimizing survey planning.
- To enhance the accuracy and completeness of BIM documentation for complex heritage buildings.
Main Methods
- A two-phase hybrid approach combining terrestrial laser scanning (TLS) and unmanned aerial vehicle (UAV) photogrammetry.
- Development of a Predictive Scan Feasibility Estimation Model (PSFEM) based on site parameters.
- Validation on a chapel case study, comparing coverage and accuracy between phases.
Main Results
- Phase 1 (TLS/ground photogrammetry) achieved 54% coverage due to occlusions.
- Phase 2 (UAV photogrammetry + supplemental TLS), guided by PSFEM insights, reached 96% coverage.
- Comparative analysis confirmed consistent accuracy and improved geometric completeness with the hybrid approach.
Conclusions
- The hybrid Scan-to-BIM workflow, enhanced by predictive planning, significantly improves BIM data completeness and reliability.
- The PSFEM offers a valuable decision-support tool for reducing redundant site visits and optimizing survey strategies.
- The proposed framework is a transferable and scalable solution for documenting heritage and complex buildings efficiently.

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...
Charting by Exception, or CBE, is a method of documentation used in healthcare, particularly in nursing, that focuses on documenting only significant or abnormal findings rather than recording every detail. This approach aims to streamline the documentation process, improve efficiency, and ensure that healthcare providers can quickly identify deviations from normalcy in patient assessments.
In CBE, healthcare professionals establish predefined standards of practice that define what constitutes...
The Problem-Oriented Medical Record (POMR) revolutionized medical record-keeping by introducing a systematic approach focusing on the patient's problems rather than merely listing symptoms. Dr. Lawrence Weed's introduction of this method in the 1960s marked a significant advancement in medical documentation. The POMR framework consists of four key components: the database, problem list, plan of care, and progress notes.
Database: This section documents crucial medical information...
Problem-intervention-evaluation (PIE) is a systematic approach to documentation used in healthcare settings for clinical decision-making and patient care planning. It is a structured approach to organizing patient data based on problems, interventions, and evaluations. Here's a breakdown of its key features and considerations:
Problem: Patient care is organized around issues identified or nursing diagnoses in the PIE system. Each problem is labeled with a "P" followed by a number....
The case management model is a multidisciplinary approach that involves healthcare professionals from diverse disciplines, such as physicians, nurses, therapists, social workers, and pharmacists, working collaboratively to address the various needs of patients. Each healthcare professional brings unique expertise and perspectives, contributing to a more comprehensive understanding of the patient's condition and tailoring treatment plans accordingly.
For example, a patient with a chronic...
