Collaborative multidisciplinary learning : quantity surveying students’ perspectives
The construction industry is highly fragmented and is known for its adversarial culture, culminating
in poor quality projects not completed on time or within budget. The aim of this study is thus to
guide the design of QS programme curricula in order to help students develop the requisite
knowledge and skills to work more collaboratively in their multi-disciplinary future workplaces.
A qualitative approach was considered appropriate as the authors were concerned with gathering an
initial understanding of what students think of multi-disciplinary learning. The data collection
method used was a questionnaire which was developed by the Behaviours4Collaboration (B4C)
team.
Knowledge gaps were still found across all the key areas where a future QS practitioner needs to be
collaborative (either as a project contributor or as a project leader) despite the need for change
instigated by the multi-disciplinary (BIM) education revolution.
The study concludes that universities will need to be selective in teaching, and innovative in
reorienting, QS education so that a collaborative BIM education can be effected in stages, increasing
in complexity as the students’ technical knowledge grows. This will help students to build the
competencies needed to make them future leaders. It will also support programme currency and
delivery
An approach for real world data modelling with the 3D terrestrial laser scanner for built environment
Capturing and modelling 3D information of the built environment is a big challenge. A number of techniques and technologies are now in use. These include EDM, GPS, and photogrammetric application, remote sensing and traditional building surveying applications. However, use of these technologies cannot be practical and efficient in regard to time, cost and accuracy. Furthermore, a multi disciplinary knowledge base, created from the studies and research about the regeneration aspects is fundamental: historical, architectural, archeologically, environmental, social, economic, etc. In order to have an adequate diagnosis of regeneration, it is necessary to describe buildings and surroundings by means of documentation and plans. However, at this point in time the foregoing is considerably far removed from the real situation, since more often than not it is extremely difficult to obtain full documentation and cartography, of an acceptable quality, since the material, constructive pathologies and systems are often insufficient or deficient (flat that simply reflects levels, isolated photographs,..). Sometimes the information in reality exists, but this fact is not known, or it is not easily accessible, leading to the unnecessary duplication of efforts and resources.
In this paper, we discussed 3D laser scanning technology, which can acquire high density point data in an accurate, fast way. Besides, the scanner can digitize all the 3D information concerned with a real world object such as buildings, trees and terrain down to millimetre detail Therefore, it can provide benefits for refurbishment process in regeneration in the Built Environment and it can be the potential solution to overcome the challenges above. The paper introduce an approach for scanning buildings, processing the point cloud raw data, and a modelling approach for CAD extraction and building objects classification by a pattern matching approach in IFC (Industry Foundation Classes) format. The approach presented in this paper from an undertaken research can lead to parametric design and Building Information Modelling (BIM) for existing structures. Two case studies are introduced to demonstrate the use of laser scanner technology in the Built Environment. These case studies are the Jactin House Building in East Manchester and the Peel building in the campus of University Salford. Through these case studies, while use of laser scanners are explained, the integration of it with various technologies and systems are also explored for professionals in Built Environmen

Using airborne LiDAR Survey to explore historic-era archaeological landscapes of Montserrat in the eastern Caribbean
This article describes what appears to be the first archaeological application of airborne LiDAR survey to historic-era landscapes in the Caribbean archipelago, on the island of Montserrat. LiDAR is proving invaluable in extending the reach of traditional pedestrian survey into less favorable areas, such as those covered by dense neotropical forest and by ashfall from the past two decades of active eruptions by the Soufrière Hills volcano, and to sites in localities that are inaccessible on account of volcanic dangers. Emphasis is placed on two aspects of the research: first, the importance of ongoing, real-time interaction between the LiDAR analyst and the archaeological team in the field; and second, the advantages of exploiting the full potential of the three-dimensional LiDAR point cloud data for purposes of the visualization of archaeological sites and features
Structured Land Domain Modeling for Sustainable Land Administration in Sri Lanka
Developing countries face challenges in identifying suitable land due to insufficient administration systems, leading to governance issues and economic decline. A well-functioning land administration system is crucial for development. This technical paper elaborates an easy pathway to develop a local land administration Domains toward an effective and efficient Land Administration. Introduction of Land Fabric Domain (LFD) and the Localized Land Domains (LLD), are new concept for structuring of land parcels at comparatively low accuracy but well-defined topologically adjusted feature classes to manipulate as electronic information base to sustain the national land administration, real estate management and spatial data infrastructure development. The system architecture designs and the descriptive feature class overview elaborate the land administration system developers to begin their own LLD systems and interactive collaboration with national domains in order to manage overall system compatibility and consistency. The research focuses on the land information system (LIS) currently maintained and operated by the Survey Department and national issues in sustainable land administration of the country. Research focuses to analyze the prevailing process and outcomes of the LIS and introduces possible successive system architectures for implementation. The introductory LFD will be discussed against the feature topology on the basis of geospatial data science and then detailed feature classification will further be discussed accommodating entity relation diagrams. Proposed LLD with process architecture models will be conceptualized for successive implementation. The localized land domains will be structured and interactively linked through national LADM ISO-19152 guidelines for sustainable land administration of the country
