GIS and underground utility mapping services can accurately identify existing services but the challenge for the infrastructure designer lies in consolidating and using this information effectively.
Information about potentially conflicting utilities, often provided in varying formats, must be easy to import and decipher. Proximity and crossing service issues in the layout drawings and on the longitudinal and cross section plans need to be immediately visible and the process of generating a realistic design which accommodates the existing entities must then be intuitive and logical. CIVIL DESIGNER allows the designer to work effectively with survey data or with drawing entities. ASCII files and other formats of drawing data can be imported directly into CIVIL DESIGNER's Crossing Services database and drawing entities can be added graphically in a Crossing Services Editor tool.
Multiple databases of crossing services information such as sewer pipes, stormwater culverts, water networks, electrical layouts and telecommunication cables can be created. This information will be interrogated by the program such that unacceptable proximity positions and clashing points of utilities on road, sewer, storm, water and terrain string long sections, as well as on road vertical alignment views will be indicated. Each crossing service can be displayed with distinct colours, line styles and annotations
CIVIL DESIGNER can automatically generate skew cross sections for every crossing service and allows the engineer to step through the chainages of a road
and view the associated cross sections in the cross section editor. It is also possible to step through the crossing services themselves,
rather than each chainage increment, which is particularly useful for long road designs.
Interaction Between Design Elements
CIVIL DESIGNER maintains design integrity by replicating all the pertinent aspects of a project. Each module queries the other design modules when it needs to. The services database can also be used to indicate the positions of existing pipes/cables/services on long sections, layout plans, sub-surface 3D fly-throughs as well as in the vertical alignment control panels. At all times a realistic simulation of the project at hand is upheld. Potential clashes with existing services can therefore be avoided early on in your design, saving time and money on site.
