Parking lots / slabs

[freeriderfx]

Hi everyone, what would be the best practice to make / solve parking lots or construction slabs on a given toposurface.

I want to achive my pave final level something as the picture

What is the problem you are having to start with? if this is a general question, their are several but which is the best practice that is something you need to decide...

1. There are many who are in love with site designer which can produce something close to what you have shown
2. some prefer to work with topo subregions, paint and materials and some entourage families 
3. other use grading >> building pad >> Floor  >> some railing for the kurbs and retaining walls + some face based families for the marking

It is up to you and what you want to make out of the model...after all, best practices aren't universal 🙂 they are determined by each individual or group of individuals based on what suits best to achieve certain requirements on a project.

Well site designer is not that clear and "easy to use" i have many doubts onhow to use it.

I need to model the parking lot of a big project. As the project advance the surface need to adjust, so i need to "manipulate" the slabs with multi slopes.

[freeriderfx]

the method I was using the method of dividing the toposurface and modifing it to the multislope, but now is not an option because i need "real" objects or phycical parking lot slabs

@freeriderfx  me too, I don't like site designer … if you need real quantifiable elements, then you could use the third option proposed above grading, pads and sloped slabs or floors with modified subelements and for kurbs and line marking you could use railing

Do you actually have Grading Plans? How about a Revit Toposurface?  

[freeriderfx]

We do have grading plans. But I need now to have a "physical" object that can appear in my sections and can be manipulate as the construction goes on. So a toposurface can´t be an option.

[freeriderfx]

I used to model a mass, then, the give to the four corners the level, after that I put a floor by face.
but handle the toposurface after that is a little messy. 

[barthbradley]

If you have a Revit Toposurface, then use a Building Pad for your Parking Lot.

You can use a building pad to 'grade' the topo and build a floor atop the pad for sub element modifications. Or you can use Dynamo to convert a portion of the topo to a floor.

I don't know, I've never worked with masses/toposurface combo unless I am using Dynamo...if dynamo isn't part of your workflow, I believe method 3 mentioned in reply #2 above is a better option 

[freeriderfx]

well I finally got something I can work with, here´s what I did.

1.- I put a bulding pad below the lowest level. So i can have a visible portion of the final slab of the parking lot.

2.- then, model a mass with the shape of the first part of the lot, then with the base being on a "survey level" I made a substraction between the base level of the mass (1,985) and the level I needed in the first corner and so with the other 4. Then, I put a floor, and gave the lowest level to the correspondent corner. And to the other three cornes I modified the point and make to be in the place of the corner of the ´previous mass.

I would suggest that you create the existing Toposurface in the "Existing" Phase (w/ "Phase Demolished"="None"), go to "New Construction" Phase create a Graded Region Copy of the Toposurface, and then create your  Building Pad (e.g. Parking Lot) in New Construction Phase. If you need to further "refine" the Toposurface, make those final grading modifications to the "New Construction" Graded Region Copy of the Toposurface.  Done this way, all Cut and Fill work be the reportable thorough a QTO. 

FWIW:

1. Building Pads are exactly like Floors, in that they can be layered (e.g. Asphaltic Concrete over Aggregate Base).

I still do not get the purpose of the mass any how does it all look like all together now with pad, mass and floor...but hey! if you are happy with it, that's what count 🙂

[freeriderfx]

[barthbradley]

I don't get it. What are you doing?  I'm thinking we are all on a different page than you are.  Want to post the file?

@freeriderfx 

Sorry; I still don't get it why you need a mass

1.  Building pad to grade
2. Building pad gives you a slab...modify its structure to 2-3 layers ex: sub base/base coarse/wearing coarse
3. add another floor element on top of and add the layers required for the interlock pavers and laying material
4. adjust the sub elements of the floor element in 3 to the levels of the parking
5. assign materials 
6. use a face/line based generic family for the kurbs, railing for retaining walls, paint line marking and you are done

I can think of 3 other ways to do it without a Mass...I don't know Im just not sure how the mass is fitting in there! Again as stated 🙂 if you are happy with your workflow, go for it mate.
