RE: Pointloads on groundlevel
It is not difficult. One can model crane loadings (as concentraded pointloads or multiple pointloads) and moving vehicles (according to NENEN 19912+C1:2011) above the pipeline. It is no problem if there is asphalt above, you can use the equivalent depth of cover calculation for this conform the NEN 36501 article C.5.2 (Effect of road constructions in reducing traffic loads). The H_eq can be used then in Braunstorfinger.
In the NENEN 19912+C1:2011: the following vehicles pointloads are given:
Load Model 3 (Graph I Figure C.17, NEN 36501)
Fatigue Load Model 2, Lorry 1
Fatigue Load Model 2, Lorry 2
Fatigue Load Model 2, Lorry 3
Fatigue Load Model 2, Lorry 4 (Graph II Figure C.17, NEN 36501)
Fatigue Load Model 2, Lorry 5
There are more loading combination in the NEN=EN 19912, for example for special vehicles.
