Micromorphological description of vernacular cob process and comparison with rammed earth

Past builders have developed very low-embodied energy construction techniques optimizing the use of local building materials. These techniques are a source of inspiration for modern sustainable building. Unfortunately, this know-how was orally transmitted and was lost as earth construction fell into disuse during the 20th century in European countries. The absence of written documents makes necessary to use an archaeological approach in order to rediscover these construction strategies. Micromorphological analysis of thin sections collected in earth building walls was used for the first time to describe cob construction technique and highlighted several typical pedofeatures allowing to clearly identifying this process. Finally, a first comparison of the cob and rammed earth micromorphological features permitted to identify two key factors to distinguish these two techniques, the manufacturing state (solid or plastic) and the organization of the material in the wall.

Construction site safety in Hong Kong

The structural characteristics of the Hong Kong construction industry, most notably its elaborate system of subcontracting and the casual basis on which labour is employed, pose serious problems for safety managers. By international standards, Hong Kong's construction industry performs very badly in the area of safety. Recent work in the UK and Finland highlights the effectiveness of behavioural techniques to improve safety performance on construction sites. Work is currently under way to test these techniques in the Hong Kong construction setting. The structural properties of the Hong Kong construction industry have been taken into consideration and labour commitments to the group and to the organization have been identified for additional consideration in research. It is expected that these variables will intervene in the application of behavioural techniques to determine their effectiveness. This paper investigates the theoretical background to commitment at the group and organizational level and presents a site level research model which is illustrative of the possible effects that group and organization level commitment may be found to have on the use of behavioural techniques.

Critical evaluation of cognitive analysis techniques for construction field management

Cognitive analysis techniques to document field personnel's knowledge have been a recent topic of interest in construction. However, the decision to utilize such techniques remains a difficult one, given their perceived complexity, their variety of scopes and means and their expected limitations for utilization in jobsites. This paper presents a critical review of cognitive analysis techniques to analyze their value for construction management research. The evaluation is geared towards identifying the function of different types of techniques as well as constraints for their implementation in construction environments. In the evaluation, the components of techniques are dissected to uncover their individual capabilities and applications, while also providing insight into the actual difficulties to collect and represent knowledge. This analysis is complemented by the authors' experience in previous cognitive analysis studies, which helps produce a set of recommendations about the practical challenges and implications of deploying specific techniques in construction jobsites.

An object-based 3D walk-through model for interior construction progress monitoring

The complicated nature of interior construction works makes the detailed progress monitoring challenging. Current interior construction progress monitoring methods involve submission of periodic reports and are constrained by their reliance on manually intensive processes and limited support for recording visual information. Recent advances in image-based visualization techniques enable reporting construction progress using interactive and visual approaches. However, analyzing significant amounts of as-built construction photographs requires sophisticated techniques. To overcome limitations of existing approaches, this research focuses on visualization and computer vision techniques to monitor detailed interior construction progress using an object-based approach. As-planned 3D models from Building Information Modeling (BIM) and as-built photographs are visualized and compared in a walk-through model. Within such an environment, the as-built interior construction objects are decomposed to automatically generate the status of construction progress. This object-based approach introduces an advanced model that enables the user to have a realistic understanding of the interior construction progress.
