Construction project involves participation of various stakeholders, contractors, and agencies for timely and effective completion. Each activity and resources of contractors are preplanned to avoid delay of project. Planning, designing and scheduling of structure are done with the help of available software’s. But this software’s still lack feature of providing related construction information in 3D model and also there isn’t any system available which can handle all project related information and documents on single platform. 4D Geographic information system (GIS) model is created by inter-linking schedule of activities and computer aided designs (CAD) drawings on GIS platform for G+4 building located in Navi Mumbai, India. The developed model can handle all project related database on single platform. Proposed methodology helps in determining incompleteness and logical errors in scheduling or designing and helps us to determine feasible route for manpower and material movement from different locations to construction site. 4D GIS model maintains spatial data such as different 3D components of structure in separate layers which is geo-referenced spatially and necessary nonspatial information such as dimensions, materials required, schedule, related documents, persons responsible, safety and quality control recommendations, site expenditure and material inventory are stored in attribute tables. This research concludes that GIS model can create real time building construction information database

A Construction project involves project management and financial planning at various stages right from the concept stage to the execution stage. This involves a large number of people working on different aspects of the project adhering to their specific job roles in collaboration with the others. These members not only work on the different aspects but also work on different software’s and platforms in order to create a holistic working plan to ensure timely and flawless construction activities. But these software’s only provide specific information feeded to it. A single program which would provide information of all these software’s collectively on one platform would not only make it convenient for sharing data but also help in reducing the delay and eliminating errors. A 5D model can be created linking the schedule of the project and the cost involved in it to the drawings on a GIS platform. In this research a 5D model of a Residential cum Commercial project Located in Prabhadevi, Mumbai, Maharashtra, India has been generated. This model includes the data related to the Schedule and Cost of the project, which can help in making decisions related to monetary aspects, Men & Material preparedness, verification of bills & Billing Audits. A 5D model holds Spatial data such as Project Schedule, Itemized Element costs and Quantities along with the 3D model of the structure. The conclusion of the study states that a GIS Model can serve as a real time data base for all the parties involved in the project at every level of its progression.

This article attempts to solve the problem of systematizing and structuring of the information base in relation to the activities of spatial structures on the example of the cities of Khabarovsk and Komsomolsk-on-Amur, which host the territories of advanced social and economic development (TASED). Collecting, storing, analyzing and visualizing the spatial data and related information has required using geographic information system (GIS). To ensure its correct functioning, it is necessary to form an information base of socio-economic indicators (the principles of their selection are explained). The results show that contemporary Russia lacks unified approaches, a legally approved methodology for assessing the effectiveness of TASED activities, and an information base. As part of the creation of the information basis of GIS-model of spatial development centers for the formation of a pool of indicators, the authors have analyzed the results of socio-economic development of Khabarovsk and Komsomolsk-on-Amur and the corresponding TASED Khabarovsk and Komsomolsk. According to the results of the analysis, the following areas and indicators were determined: the geographical location of the territory and logistics conditions, the level of value added redistribution, population, labor market, wages, the volume of shipped goods of own production, investments in fixed assets, the budget of the municipality. The authors prove that the formed information base is sufficient for building a GIS model, and it allows to describe the key parameters of the processes in the context of the Russian regions and cities which employ TASED to develop these cities as centers of spatial development, and meets the requirements with integrity and consistency.

Application Potential

Objectives. At present, medical thermal imaging is still considered a mere qualitative tool enabling us to distinguish between but lacking the ability to quantify the physiological and nonphysiological states of the body. Such a capability would, however, facilitate solving the problem of medical quantification, whose presence currently manifests itself within the entire healthcare system. Methods. A generally applicable method to enhance captured 3D spatial data carrying temperature-related information is presented; in this context, all equations required for other data fusions are derived. The method can be utilized for high-density point clouds or detailed meshes at a high resolution but is conveniently usable in large objects with sparse points. Results. The benefits of the approach are experimentally demonstrated on 3D thermal scans of injured subjects. We obtained diagnostic information inaccessible via traditional methods. Conclusion. Using a 3D model and thermal image data fusion allows the quantification of inflammation, facilitating more precise injury and illness diagnostics or monitoring. The technique offers a wide application potential in medicine and multiple technological domains, including electrical and mechanical engineering.

Indoor Spaces

Sophisticated indoor design and growing development in urban architecture make indoor spaces more complex. And the indoor spaces are easily connected to public transportations such as subway and train stations. These phenomena allow to transfer outdoor activities to the indoor spaces. Constant development of technology has a significant impact on people knowledge about services such as location awareness services in the indoor spaces. Thus, it is required to develop the low-cost system to create the 3D model of the indoor spaces for services based on the indoor models. In this paper, we thus introduce the rotating stereo frame camera system that has two cameras and generate the indoor 3D model using the system. First, select a test site and acquired images eight times during one day with different positions and heights of the system. Measurements were complemented by object control points obtained from a total station. As the data were obtained from the different positions and heights of the system, it was possible to make various combinations of data and choose several suitable combinations for input data. Next, we generated the 3D model of the test site using commercial software with previously chosen input data. The last part of the processes will be to evaluate the accuracy of the generated indoor model from selected input data. In summary, this paper introduces the low-cost system to acquire indoor spatial data and generate the 3D model using images acquired by the system. Through this experiments, we ensure that the introduced system is suitable for generating indoor spatial information. The proposed low-cost system will be applied to indoor services based on the indoor spatial information.

Design Bid Build

Design-Bid-Build (DBB) or commonly known as Traditional method is the earliest and most prevalent procurement method used in Malaysian construction industry. Design-Build (DB) and Construction Management (CM) procurement methods were later introduced in Malaysia as an endeavour to satisfy and accommodate the increase in project complexity and the need for avoiding drawbacks of the Traditional methods. Each procurement method has different nature and possesses certain characteristics. Therefore, this study was carried out to ascertain and compare the characteristics of these three procurement methods that are implemented in building construction projects in Malaysia. A questionnaire survey was conducted among architects, consultants, contractors and owners or developers to elicit their feedback on the characteristics which were categorised into time, cost, quality, complexity and flexibility, degree of involvement and responsibility allocation and technical expertise. The findings indicated that only DB method almost fulfils all the characteristics under the six categories, whereas, DBB methods garnered agreement only for certain characteristics under time, cost, complexity and flexibility and technical expertise categories. Meanwhile, the only CM method’s characteristics that satisfy agreement from the respondents are the often used of fast track approach and lack of certainty in price. This study concludes that when a procurement method is adopted for a construction project, not all the features or characteristics will turn out as expected. There are many factors that contribute and are influential on the success in procurement methods that are worth for further investigation.
