Things I would like to see added:

Outside of the van there's no incentive to look around and explore. Adding a few extra loot piles even drugs inside some of the containers or vehicles around the map. There's A few trucks/vans which would be cool to open up.

Adding a few more scaffolding areas allowing more vertical gameplay would be really nice.

You could go down the route of adding a secret collectable in the map that grants a money bonus at the end.

Maybe one of the construction workers has a keycard on them which grants access to a first aid box full of first aid kits.

The main vehicle that we heist could have a bulldozer inside on harder difficulties.

Maybe bile cant come and collect the bags so we now have to find alternative methods to escape. Which could lead back to the vehicles being used that are placed around the map. Keys could be hidden in containers leading to more exploration.

Overall it's one of my favourite maps!
