SimuSurvey: a computer-based simulator for survey training

Abstract: This paper presents the development of a computer-based simulator for survey training, referred to as SimuSurvey. Because modern survey instruments are usually expensive, difficult to maintain, and sensitive to weather conditions, surveying course instructors often find it difficult to supply sufficient high-quality instruments for the class. Also, the instructors often suffer the need to repeat similar instructions about instrument operations to individual stu-dents; and, lack a good means of recording each studentís learning progress. SimuSurvey was designed to address these issues - for use in survey training in a computer-generated virtual environment at a low cost. The functions cur-rently provided by SimuSurvey include: (1) the visualization of a survey instrument and measurement poles involved in an assigned survey task; (2) the simulation of the control interface of a real surveying instrument; (3) the recording of each studentís performed operations; and (4) design of learning activities for students to practice surveying tasks in a simulated environment. The focus of this paper is on the design and implementation of SimuSurvey. An example is pro-vided to demonstrate the applicability and effectiveness of SimuSurvey to survey training.

Assessing the Effectiveness of Virtual Environments for Learningthe Fundamentals of Surveying and Construction Layout: Initial Findings

Abstract: The practice of Surveying and Construction layout is one of the fundamental skills that need to be acquired by an engineering or construction management student. Mastering these skills require extensive training with the equipment and team members in order to achieve both precision and accuracy in measurements. In additional to getting used to the equipments, the mastering of the technique requires the students to follow procedures accurately. This paper presents the results of testing a surveying and construction layout game. The game is a first step in a plan to develop a Virtual Reality VR surveying education tool, where students will practice by interacting with a real time computer generated imagery (CGI).The test involve students who have been enrolled in the surveying class for the spring semester 2010. The students are asked to perform a specific surveying task. The students attempts are documented based on their ability to follow the correct procedures and on their ability to choose the correct needed equipment. The paper will show the results of the students ability to follow the correct procedures needed to achieve the appropriate level of precision and accuracy. The results of this test will help make the case that Virtual Reality tools can reinforce the learning of hands on classes such is the case for Surveying and Construction Layout.

Data models for geometrical physicality and material information for on site implementation in surveying

Abstract: This article describes a new method of collecting and utilizeing the information needed for renovation of existing buildings. The method is called the RENO-system and it has been developed in Tampere University of Technology. The most remarkable properties of the system are the fully three-dimensional model of a building linked together with a relational data base management system to store material and other attribute information during on site surveying. In the system development special attention has been paid to eficiency: producing the three-dimensional model of a building is almost as cheap as producing the two-dimensional drawings by conventional methods. The new method can also be used solely for room and material inventory. The three-dimensional CAD-program running together with the relational data base management system enables effective processing of the information. The RENO-system can generate graphical information suitable for the most common CAD-programs and the data base interface uses SQL-standard, from which the information can easily be transmitted to other programs. Of course the three-dimensional data can not be processed with a two-dimensional program, but in general the RENO-system can produce renovation information in any form required by customers. The result of this research defines the data model to input the physicality of spaces. Also the result involves the definition of the surveying method for source information procurement in existing environments regardless of whether the object to be modelled is a building or part of town.

Development of a knowledge-based system for strategic costplanning of construction projects in hong kong

Abstract: Cost estimation of construction projects is a difficult and complex task especially inpreliminary stage of design. For many years, construction costs have been estimated byexperienced personnels, such as quantity surveyors or cost engineers. However,underestimation and overestimation do occur. With the lack of detailed information onthe construction site and building itself, a precise cost estimate for a construction projectis hardly achieved. Hong Kong has significant construction activities. A fast andaccurate knowledge-based system that can give expert knowledge during the initial costplanning stage would increase its competitiveness. In the new era of informationtechnology, many research projects in information technology and knowledge-basedapplications for construction industry have been established. The authors investigate theuse of knowledge-based approach to perform cost estimation on construction projects atearly conceptual stage. Knowledge for Hong Kong situation has been established inpractical terms by collaborating with several quantity surveying firms or departmentslocally. The proposed system could be used for training fresh graduates andundergraduate students about construction cost estimation in Hong Kong.

An intranet-based integrated construction project management system

Abstract: This paper will explore the feasibility of using Internet technologies to build an integratedconstruction project management system for a contractor. Internet technologies refer towhat are commonly used in the Internet. They include hardware equipment such ascomputer, modem, telecommunication devices, network cabling; and software such asTCP/IP, HTTP, FTP, SMTP and so on. When these internet technologies are employed ina corporate environment in which there is either (i) no connection to the Internet at all, or(ii) a security system (e.g. firewall) to separate the corporate network from the Internet, thesystem becomes an Intranet as commonly known nowadays. By using Internettechnologies, a contractor can set up a corporate LAN in the head office. Project offices arethen linked to the corporate LAN by telecommunication such as dial-up, leased line orframe relay. A corporate database can be set up with a Web interface so that all queries,data input and output to the database can be done via a Web client. Modules that areapplicable to a contractor include (i) electronic mail; (ii) tendering and estimating; (iii)purchasing; (iv) quantity surveying (interim payments, claims, variations); (v) documentmanagement; (vi) quality assurance; (vii) project accounting. An integrated system is seenas of utmost importance in a contractor's environment. The advantages of using Internettechnologies and this system will be discussed. An implementation schedule will bepresented. Possible difficulties such as organizational and technical issues will bediscussed too. Possible extension of the Intranet to an Extranet will be explored.

Experimentation of Collaborative Learning for Construction Estimating

Abstract: The success of project documentation and implementation depend on an effective collaboration within project teams. However, fragmentation has been a major concern in the industry for many centuries. Evidence suggests that this phenomena challenge weakens value integration among project teams; and regrettably, most academic programs are still tailored to service this limitation. As BIM is driven by integrative skills, this paper describes the formulation of an academic course for a multidisciplinary and integrative study of an estimating course. Specifically, it is targeted at a class of undergraduate students with backgrounds in project team disciplines ‚Äď architecture, quantity surveying, structural engineering and services engineering. The focus is to engage students in collaborative learning such that they are able to develop technical briefs, design tender programmes, estimate and analyze tenders. A model for formulating groups and group assignments is proposed. At the end of the experimentation, study outcomes reveals that students are multi-skilled and are better team players than those under fragmented learning environment. Conclusions are drawn on curriculum development for integrative innovations such as BIM and virtual project management.
