Case Study#2: An inclined elevator and a stairway to heaven


DNB’s new headquarter consist of three buildings with a underground story that connects the buildings together. The building to the far west is designed by Dark Architects, and since the shape of the building i like a stair, it is not a strait forward answer how to make the internal flow efficient with minimum amount of cores. There is also a public roof and a restaurant on the top of the building, so in addition to find the best solution for the many employees in the building, we also had to work out how we could bring the many guests to the spectacular view from the public roof.

The solution was an inclined public elevator that is more than 110 meters long that only stops at ground floor and the top floor, and along the elevator shaft there is a strait stair that connects all the floors in the building.   This stair has many names such as «Stairways to heaven» and recently there has been a competition who can be the fastest up all the 303 treads (


The design process was a joyful ride. When a horizontal slab meets an inclined slab, there will always be some interesting discussion. In addition will the angel of the inclined elevator have direct impact on how the stair will be, since everything is dependent on each other. To feed the project with valuable drawings, I had great success to combine regular floor plans / sections together with isometrics 3D views.



In this project we started using ebeam, and we found it very useful in many meetings and discussions. Suddenly everybody could draw something that everybody could see and participate in.

Case Study#1: Façade casettes

DNB’s new headquarter consist of three buildings with a underground story that connects the buildings together. The building to the far west is designed by Dark Architects, and the concept for the facade was to give it a heavy and solid expression. We did this by playing with different depths and by using a black granite as the facade material. DnB Vestbygget - Jiri Havran - (6)


The sizes of each cassettes is 900mm x 900mm and they are made by gluing 4 mm granite to an aluminium honeycomb system. In total we have more than 6100 cassettes with more than 350 different types. If we are only counting the types there are more than 10 cassettes, we are down to only 25 different cassettes types. With these 25 different types, we cover more than 90% of the facade. 2.naturstein_Page_02   2.naturstein_Page_06 To stack all the different cassettes the way we wanted, we tagged all the cassettes on the production drawing. Since they were going to start mounting from the left of the building, we also added which container every cassette should be shipped in. This to make it more efficient on the construction site. 2.naturstein_Page_10  
Every cassettes is drawn in 3D so we were in total control of the details.2.naturstein_Page_082.naturstein_Page_09

Family training#2 -CWpanel and to be in contol of the directions

I have really been puzzled about how Revit are defining direction of a CWpanel. Yes, when you have a CW the direction is easy. Up is up, and down is down. But what about glazed roof. How can i control the direction of the panels? This is really essential in many occasions.

I think I have started understanding it but I actually not very happy with the answer.

Lets use the CWpanel from the previous panel as an example. I have made two different CWpanel where the only difference is the direction of the profiles («Vertical planja 70″ and Horizontal planja 70»).

I then insert the «Vertical» panels into i Sloped Glazing that is completely flat.

Screenshot 2014-06-11 14.36.12


Since it is a flat Glazing there is no up and down, and therefor the direction of the panel is not determined to any elevation. So how can I know how Revit will place the Curtain Panel within the CW?

Well, if you notice the ViewCube you will notice there is an «UP» and as far as I know this will be the «UP» as well for the panel.


Lets say you want to rotate your panel 90 degrees . The only way you really do that is to replace your vertical panel with the Horisontal panel. If you try to rotate the angle with Grid 2, you will notice that you maximum can rotate the angle by 89 degrees.

Okay, what happens if I now make a slope on my Sloped Glazed roof? I keep my «Horizontal» panel and add a sloped arrow in sketch mode.

Screenshot 2014-06-11 14.36.51

I will then get a error «can’t make type «Horisontal_…», so I have to replace the panel and then replace the Horisontal panel once again. The thing you notice is that the panel now have rotated 90 degrees.

The only way to rotate the panel to the right position now is to replace the Horizontal panel with the Vertical panel.

Screenshot 2014-06-11 14.38.07

The conclusion is obvious. When there is no slope, the ViewCube is driving its direction. But when you have a sloped roof, the elevation overriding the ViewCube. This is maybe not a surprise, but it is kind of frustrating when you have to make two different panels, horizontal and vertical, to be able to rotate the panel 90 degrees. It is after all the same type of plate.

In addition, have you ever tried to mirror a Sloped Glazing? Or a Curtain Wall? The inside/outside will be rotated as well…

Family training#1 -CWpanel with array

Sometimes you really want to make something quick (and dirty) but that works for your need. So if you want a roof, a wall or a wall, that don’t have a flat surface, you could use a curtain wall with an adjustable curtain wall panel (CWpanel).

Lets say you are going to make a roof with this profil:





You could start making a profile family with the same measurements as the profile above. Then you sweep this profile in a generic family, with the length of the sweep path as a type parameter:


Load this family in the CWpanel and make a array function as shown in the picture below. Use as well the height parameter for the CWpanel as the parameter for height in the sweep.


There you go. You have now a roof, a floor, a wall, with you preferred profile.


PS! another way of doing it is to use the profile to make a mullion, and then use this in the CW. Then you make a CWpanel that is empty.

From «Personal Computer» to «Project Computer»

We have recently starting to optimize how we are managing the pc’s at the office. Previously it was like everybody had his own stationary computer, and when somebody changed the project they were working on, they simply took the PC with him.

Now we are trying, to a certain point, to think of what type of PC’s do the projects need. And therefore the PC is not a Personal Computer, but a Project Computer.

The way we tried to do it, was to categorize the project in three; red, yellow, green. The projects that are «red», don’t have a big need for much PC power. Yellow, is these general project with not much ifc, imports, medium scale. Green, yeah they need some horsepower.

In the same way we have categorized every PC in the office; red, yellow, green. From bad to good. This has of course be updated as the time goes and new needs are to be filled.

So, a green project needs a green PC. And yes, a yellow project needs at least a yellow PC, and a red project need at least a red computer.

Complicated? Not really. Since we only are 50 employees at our office, and a lot of similar PC, it is doable. It is actually a good way to communicate to your bosses when you are saying that now we really need to by new PC’s.


What hardware for Revit?

We have understood that the most important things for Revit, regarding hardware…, is a great graphic cards (as the ones for gaming), fast HD, a lot of RAM.

Any opinions?

The PC we are buying at the moment for Revit is:

GTX 780
Fractal Design Define R4 Black Pearl
Corsair TX 650M, 650W PSU
Intel Core i7-4770K
Corsair H100i Hydro Series CPU Kjøler
ASUS SABERTOOTH Z87, Socket-1150
Crucial DDR3 Ballistix Tactical 32GB
Gigabyte GeForce GTX 770 2GB PhysX CUDA
Samsung SSD 840 EVO 250GB BK OEM
