Accurate Estimation

Earthmoving operations represent a sizeable percentage of highway construction costs. Accurate estimation of cut and fill quantities, as well as haul distances, are thus essential for developing realistic schedules and reliable cost estimates for highway construction projects. This paper presents a model designed to aid highway construction personnel in optimizing earthmoving operations by developing realistic mass haul diagrams. The model automates data acquisition and accounts for the presence of different soil strata and natural and (or) man-made obstructions affecting earthmoving plans. Geographic information systems (GIS) are employed to generate three-dimensional digital terrain models of the topography and soil profiles. The model is supported by a relational database for soil data and has been implemented in a prototype software developed in ArcView® environment. It provides a user-friendly interface to facilitate data entry and efficient reporting capabilities. The model has flexible input and output formats designed to facilitate data sharing with a number of commercially available software systems. A numerical example is presented to demonstrate the features of the developed model.Key words: data acquisition, geographic information systems, quantity estimating, earthwork optimization.

Three Dimensional Models

With application and popularization of information modeling technology, both Geographic Information Systems (GIS) and Building Information Modeling (BIM) could represent three dimensional models in different fields. By introducing application features of GIS and BIM in Metro construction, this paper presents such a thought that effective combination of GIS and BIM may play a role at different stages in metro construction.

Management Capabilities

<p>Geographic Information Systems (GIS) provide large information management capabilities. However, in many cases the feature of the visualization of this data over a huge detailed three-dimensional terrain does not exist or are limited, wich can be very useful or desirable in many applications. This paper presents the integration of SANTI, a three-dimensional visualization system of large terrain areas and geographical data, with gvSIG, a free GIS software. We describe the capabilities of the visualization system, the approach to connect the two systems and how it is applied to a project in development for the management of the excavation of the Castro de la Lanzada located at the Galician coast (Spain).</p>

Triangulation Network

The article deals with the current problem of solid waste disposal. Also the use of geoinformation technologies in the design of environmentally hazardous facilities. The sequence of actions in case of reconstruction of a land plot for the construction of a solid waste landfill is described in detail. It shows how you can use geographic information systems to speed up and better accomplish the task. The convenience of using geographic information systems when planning such tasks is obvious. It is advisable to use geographic information systems when planning environmentally hazardous facilities. This is due to the complex nature of the problem. This requires the involvement of additional spatial data. It is the geographic information system that will allow the use of all data in the complex based on the principle of their spatial position. You can also use data models to support the creation, validation, and correction of information. In a geographic information system, you can create a geodatabase. This will create a 3D model of a solid waste landfill. The 3D model allows you to better represent the terrain. Creation of a triangulation network will allow to correlate all layers created in the geodatabase. The triangulation network is created from 3D terrain points. It allows you to get a three-dimensional model of a high-altitude polygon. This provides many possibilities in the future. It will be possible to interpret 3D models with high-precision engineering systems. This allows you to carry out any geometric measurements, build sections and profiles, as well as monitor activities at the solid waste landfill. Based on these data, it is possible to measure the volumes of household waste, areas, the height of the landfill in terms of the height of the actual relief and the level of groundwater, the altitude characteristics of the landfill and slopes to compare them with the standard indicators. The three-dimensional model will make it possible to identify inconsistencies between the actual boundaries of the polygon with the cadastral boundaries of the site allocated for these purposes. With the help of geographic information systems, simplicity, speed and clarity in the formation of conclusions and decision-making will be provided.
