Intersection point with clash or insufficient must be resolved by changing the properties (eg. location, invert level, gradient, and etc.) of drainage, sewerage, and/or water reticulation.
Example of Solution #
Vertical Clearance #
1. Check on the pipes that clashed and insufficient clearance. Determine the additional vertical clearance needed to pass the analysis.
- White – Ok
- Yellow – Insufficient Clearance
- Red – Clash
2. Make the changes accordingly.
Users can directly adjust the invert level and position of pipes (drainage, sewerage and water pipe) in 3D view.
Select pipes, and edit.
Adjust the Sewer 8 (at manhole 9 or manhole 10) Invert Level at the RHS properties box to avoid the pipe clashing vertically between Drain 11 and Sewer 8.
User may untick ‘Iterate Invert Level’ and manually key in Invert Level for Manhole 10 as image below;
3. Make sure analysis passed for Drainage, Sewerage, and Water Reticulation modules by clicking ‘Module Status’
4. Click on the ‘Analyse’ button .
Note: Now users can directly analyse utility modules directly from 3D view. Go to Main tab >> Project >> Analyse
After click analyse button, an ‘Analysis Summary’ will pop up for all three (3) utilities module;
5. Make sure the remark is shown OK for all the intersection points. Change the properties again if any intersection points still clash/insufficient.
Horizontal Clearance #
1. Check on the pipes that clashed and insufficient clearance. Determine the additional vertical clearance needed to pass the analysis.
- “-” – Intersected point at key plan but never clash
- “-Ve” – Clashed with Sump/Manhole
- “+Ve” – No clash at key plan but clashed considering the thickness of Sump/Manhole
2. The horizontal clearance is calculated perpendicularly between the entities. The thickness of the pipes is excluded in horizontal clearance measurement. This can be explained based on the image below.
Image 15 shows the measurement of horizontal clearance between the sump 12 and sewer 6 which is 576.31 mm, which explains the value of 0.576 m in the Clash Analysis report.
3. Make the necessary changes in the Infrastructure representative module.
