Hi all. I would appreciate your honest advise as Revit gurus and users in these forums - what is actually achievable through the use of Revit? We are going through a complete clean slate and building our systems from scratch to deliver a process that is intended to utilize the Autodesk suite of products to design, cost, program, procure, build and handover for continued use residential projects. We are working as the design team, the project management team, the cost consultancy, the main contractors and aiding with the O&M of buildings when in use through data analysis and management. We have opted to use Autodesk services however what is the best "set-up" to deliver this and what can we realistsically expect from the Autodesk suite? As examples:
I appreciate that is a lot of questions but I have the opportunity to start things afresh and your input would be greatly appreciated.
Many thanks.
Regarding:
Pre-design work - Sketchup or Formlit?
Why not use Revit for this? What do you anticipate that you can do in Sketchup that you can't achieve using Revit? The advantage of using Revit is that the work is done once - no transition required.
AutoCAD
I'm not sure why you would think that Revit can't be used for detail finer than 1:20. We do 1:1 details in Revit and have gone to great effort to eliminate any AutoCAD from our projects. So no, don't agree. Be aware that there is a certain amount of the project that is modelled in 3D, but it would be pointless to model smaller parts in the finer details, so the 2D detailing tools are used. Perhaps this is what you're referring to.
4D 5D
You are correct Navisworks isn't the only tool to use for coordination, but I believe that it doesn't make too much difference - depends on what the users are used to. For coordination (or collaboration), it may also depend on what the other consultants use. If you're going Autodesk, then in my opinion, use Navisworks.
In terms of costing, it depends on the quantity surveyor. You can certainly extract quantities from Revit to Excel, but the costing needs to consider other factors that are not modelled (such as formwork). There are a number of third party costing softwares available that read the Revit model.
Drawing numbering - probably depends on where you live - there are various standards for this depending on the country. Consult with the institute literature for this.
Your last point is not clear - your company defines the standards for your models and drawings.
Depends where you live. Local consultants and contractors will determine what software and workflow you are using. Normally I would plan your workflow based on your client/city deliverable and how that will work with consultants and contractors. My local industries heavily rely on PDF. Our local industries haven't gone completely digital model submission due to liability and our local municipal only accept PDF/hardcopies. Plan it base on your deliverable goal. Then built on that goal to deliver other service for your client. I find this to be much better strategy than going full on Revit without knowing it's pitfall.
As for Naviswork, we hardly use it. What I find is the visualization like Enscape actually is much more intuitive for our client, consultant and contractor. If you want to do walk through the virtual building, they can navigate using VR headset or from the comfort of their computer. There are many other software out there that have better collaboration tool than Naviswork. It all depends what you need and how easy for your client to navigate.
You still need AutoCAD. A lot of our surveyor, civil, manufacturer detail and even City open data use CAD and you have to take those information and use it in Revit. However detail drawn in CAD may not translate 100% accurately. You will still have issues like hatch turning solid in Revit. That is up to your team to know the limitation of CAD within Revit. I would try to go full detail in Revit so you don't inherit AutoCAD errors in Revit.
As template, you can look at Revit pure https://revitpure.com/blog/13-tips-to-create-a-great-revit-template to create template from scratch. If you want sample template, there are website like GSA you can use. https://www.gsa.gov/real-estate/design-construction/3d4d-building-information-modeling/guidelines-fo...
Lastly for model data management, you want to train up your BIM gurus. You can assign one person to be BIM manager or a team to look after your BIM process. Hope these answers your questions.
