Welcome to the Asana Community Forum 
I think this feedback request thread might be interesting:m for you to upvote Hourly, weekly, daily - calendar views for projects please :-)
Also how about setting up graphs under the reporting feature? See the first image added here: New! Create custom charts in project Dashboards to get more visibility into your team's work
Not sure if you also want to monitor the workload, if so take a look here.
Would that help?
