I really like how professional they are at their work! They always get back to me quickly when i ask questions or need clarification about something that is unclear from my original inquiry/project brief etc..
The best thing so far has definitely be working with them as an overall team member throughout this project - it's made communication much easier between myself & others involved within our organization (which was key given there were multiple stakeholders across many departments). Nothing specific yet but would love more interaction wtih other members who aren't directly partaking during meetings / site visits if possible :).
