Work Progress Control Plug-in

Work progress control can be made by measuring the differences between the design data (design value) and point cloud data (actual value).

　Introduction
This product operates as a plug-in of UC-win/Road, the difference is measured from the design data (designed value) and the point cloud data (actual measurement value) and each type of report on the work progress control is created. If the design data has already been maintained with LandXML etc., the work progress control report can be made easily by acquiring the work progress in 3D laser sccanning.

It is possible to manage the work progress in an efficient way by comparing and checking (Figure 1) the position from the embankment surface (earth cut surface) designed beforehand in 3DVR.

Steps of the work
The tool menu of the main body of Road is extended by installing this plug-in, and a special menu has been added.

About difference calculation
The work flow from the acquisition of design section to the aquisition of measured data is an automatic process, so the work progress control report can be made in an efficient way.
　　The main function and feature
About the construction type and structure
They are in accordance with "(3)Specification and civil engineering and construction management standards" of "Common specifications for civil works/ Administration standards for construction etc." established by the Ministry of Land, Infrastructure, Transport, and Tourism of Japan. However they are to be restricted to the earthwork (embankment and earth cut) and road earthwork etc.

About design section
As for the filling shape and cutting ground shape (including the linear), input them by using "Road edit" function which is a function embedded in UC-win/Road itself (Figure 2). It is also possible to import the design data much easily by using LandXML.

Standards for work progress control
When limiting to the above-mentioned construction type and structure, measurement item has only height, width (length of slope) and thickness. The standard value can be specified according to the object structure and other standard value such as the internal standard value unique to a specific company can also be defined (Figure 3).

About the road section
The point cloud data which can be obtained by using 3D laser scanning service of our company etc. and ground level TIN data are applied to the road section. By recognizing the road section (Figure 4), it is possible to obtain a great deal of measuremed data at every specified measurement point in a short time.

Work progress control report can be created in Excel format (supports all versions from 2000 to 2010) (Figure 5, Figure 6) and can also be printed directly (Figure 7). Since it can be made in Excel format, the report can be editted and made to the one according to the contracting agency, hence the versatility of the work progress control report.

Linkage with Photog-CAD
Photog -CAD (Developer: Japan Construction Information Center) can make a 3D model and cross-section and even assessment design document by taking pictures with a digital camera in a disaster site. In this product, the use of the digital camera is assumed as substitution of 3D laser scanner as well by recognizing the ground level TIN data generated from Photog-CAD as work progress.
　Future development
We plan to expand the utilization range of this product by obtaining feedback from users on the expectation of 3D laser scanner's improvement.
