Grass verges ruined by repeat parking on verge

Both 31 and 29 Hamilton Road are having extensive building work with skips and HGV frequently arriving to collect and drop materials off, plus site manager parking on the verges for hours at a time. They are parking and turning on the verges, tearing up the grass, leaving them as a muddy wasteland and obstructs view for cars exiting pur drive. There is a sign that says parking on verges is not allowed. Please can this be looked into?
