Automatic Detection of Windows Thermal Heat Losses in Buildings Using UAVs
2006 World Automation Congress, 2006Co-Authors: J.r. Martinez-de Dios, Anibal OlleroAbstract:This paper presents a set of infrared perception techniques for automatic detection of heat losses in windows by using autonomous and teleoperated helicopters. The paper focuses on the processing of infrared images paying special attention to the segmentation, estimation of temperature and classification of thermal heat losses in infrared images. It also presents briefly the main characteristics of the UAV platform used in the experiments. The paper includes results of experiments of infrared Building Inspection carried out in December 2005.

A visual odometer without 3D reconstruction for aerial vehicles. Applications to Building Inspection
Proceedings - IEEE International Conference on Robotics and Automation, 2005Co-Authors: Fernando Caballero, J Ferruz, Luis Merino, Anibal OlleroAbstract:This paper presents a vision-based method to estimate the * real motion of a single camera from views of a planar patch. Projective techniques allow to estimate camera motion from pixel space apparent motion without explicit 3-D reconstruction. In addition, the paper will present the HELINSPEC project, the framework where the proposed method has been tested, and will detail some applications in external Building Inspection that make use of the proposed techniques.

Single and Multi-UAV Relative Position Estimation Based on Natural Landmarks
Advances in Unmanned Aerial Vehicles, 1Co-Authors: Luis Merino, J Ferruz, Fernando Caballero, Per-erik Forssén, Johan Wiklund, J. R. Martihez-de-dios, A. Moe, Klas Nordberg, Anibal OlleroAbstract:The localization problem is usually solved in aerial robotics by means of GPS, Inertial Measurement Units (IMUs) and compass sensors, which are fused to provide UAV position estimation in a global frame. However, GPS estimates are often subject to inaccuracies and errors related to GPS failure or degradation. Also, GPS cannot be directly used for relative positioning of a UAV with respect to other objects, as for example for landing on mobile platforms or for wall following in Building Inspection.

Sustainable Building maintenance for safer and healthier cities: Effective strategies for implementing the Mandatory Building Inspection Scheme (MBIS) in Hong Kong
Journal of Building Engineering, 2019Co-Authors: Daniel W.m. ChanAbstract:Abstract The prevailing trend of Building ageing and dilapidation in Hong Kong has instigated the promulgation of the Mandatory Building Inspection Scheme (MBIS) as a statutory measure in handling the long-lasting problems related to Building decay which mostly occur in existing private Buildings aged 30 years old or longer. This paper aims to highlight the present situation of Building deterioration in Hong Kong, and to determine and explain the effective recommendations or good practices for executing MBIS through an empirical survey. Most of the respondents perceived that: (1) Establishing detailed guidelines and clear standards for Building Inspection and remedial works under MBIS; (2) Offering more technical and financial assistance from the government to property owners to aid the execution of MBIS; and (3) Enhancing the public awareness on MBIS through different media, are the three most effective recommendations or good practices for MBIS. Such findings have enabled Building owners and various industrial practitioners to equip with better knowledge and deeper understanding about MBIS for optimizing the implementation procedures in future.

An empirical survey of the perceived benefits of implementing the Mandatory Building Inspection Scheme (MBIS) in Hong Kong
Facilities, 2015Co-Authors: Daniel W.m. Chan, Henry T. W. HungAbstract:Purpose – This paper aims to review the current state of Building decay in Hong Kong, and attempts to identify and analyze the perceived benefits of implementing the Mandatory Building Inspection Scheme (MBIS) via an industry-wide empirical questionnaire survey. Design/methodology/approach – A total of 340 professional respondents who have gained hands-on experience in either new Building works or Building management or Building repair/maintenance were requested to complete a survey questionnaire to indicate the relative importance of those benefits identified in relation to MBIS. The perceived benefits were measured, ranked and compared according to the different roles of industrial practitioners, and between the residents in private premises and those in public estates. Findings – The survey findings suggested the most significant benefits derived from implementing MBIS to be: (1) Raise the overall Building safety towards residents and the general public; (2) Create more job openings and business opportunities in Building repair and maintenance services; and (3) MBIS is an effective solution to address the problems with Building decay (e.g. dilapidation and control over existing unauthorized Building works). The results of factor analysis indicated that the 13 perceived benefits of implementing MBIS were consolidated under three underlying factors: (1) Addressing Building dilapidation and assuring Building safety; (2) Improving living environment and upgrading property values; and (3) Creating more job openings and business opportunities. Social implications – As MBIS was officially launched on 30 June 2012, it is expected to be one of the proposed effective measures in resolving the long-standing problems of Building neglect and deterioration in Hong Kong and overseas, especially to those existing old private premises. Originality/value – In the long run, the number of prematurely ageing Buildings would be reduced, and the service life span of existing private premises would be prolonged. This is in line with the sustainability principle of providing a better living and working environment within the community as a whole.

Difficulties in executing the Mandatory Building Inspection Scheme (MBIS) for existing private Buildings in Hong Kong
Habitat International, 2015Co-Authors: Daniel W.m. Chan, Tracy N.y. ChoiAbstract:Abstract Hong Kong is a highly developed and densely populated city with a multitude of ageing Buildings. To maintain the Hong Kong's ageing Building stock properly and promote public safety in a sustainable manner, it is crucial to ensure that Building owners will take up the responsibility for inspecting and repairing their own properties on a regular basis. The Mandatory Building Inspection Scheme (MBIS) has been regarded as an effective measure in resolving the neglected Building maintenance problems. However, there will also be some major difficulties encountered during implementation. This paper aims to investigate the genuine difficulties in executing MBIS for old private Buildings in Hong Kong, based on an industry-wide empirical questionnaire survey. The survey findings reflected that the most profound difficulties in implementing MBIS include: (1) Difficulty in co-ordinating the individual flat owners for carrying out Building Inspection and necessary repair and maintenance works; (2) Disagreements or disputes amongst individual flat owners, owners' corporation or property management company will hinder the implementation process; and (3) Lack of property owners' initiative or owners' co-operation. After determining the key difficulties of MBIS, the research study would be significant to generate valuable insights into developing effective recommendations or measures for alleviating the barriers to MBIS success in future execution.

Overview of the development and implementation of the mandatory Building Inspection scheme (MBIS) in Hong Kong
Built Environment Project and Asset Management, 2014Co-Authors: Daniel W.m. Chan, Henry T. W. Hung, Albert P.c. ChanAbstract:Purpose – The purpose of this paper is to provide a concise overview of the problem of Building decay in Hong Kong, the current government measures concerning dilapidated Buildings and the latest development and implementation of the mandatory Building Inspection scheme (MBIS). A comparison of various MBISs from other jurisdictions of the world is also given. Design/methodology/approach – A desktop study of Building Inspection procedures, repair and maintenance policies was carried out, followed by an industry-wide opinion survey conducted by means of self-administered questionnaires. Target respondents are within the construction community of Hong Kong. The perceived benefits, potential difficulties and insightful recommendations or good practices are investigated. A comparison of the relative ranking of individual mean scores from various groups of respondents is presented in this paper. Findings – The execution of MBIS was found to be effective in enhancing public awareness of the importance of buildin...
