Hi Freddy,

Not all was done correctly. I changed it so check 

I removed the 650 mm overpass as this you have to do with a seperate piece to connect with the door list. It would make it too difficult to place the stair on his place 

You gave me no answer on this one ? I also change this  to what I think looks better . Check the stair I send you 

You have a very high offset above the step nosings . Is that needed or only on the top of the landing ? offset 70mm and the stringer on the landing is 97 mm offset ?

For a first stair it will be challenging as you want to cover an existing concrete stair so pay attention to have an accurate measuring of the concrete stair and put it in a cad program. When you have your documents and files you can import your stair to put it on top of it and check if everything fits which I doubt it will the first time. If you get your files this month you will be allowed to get a corrected set next month but You can only get 1 set of files for free per month. 

Also height check is important and check if the outside stringers will cover far enough downwards to cover the concrete stair until the finish part of the wall.

Also depending on the situation which I do not know you will have to cut out the stringers tha will remain on top of the concrete stair. This cutout can be drawn in a cad program too to adjust your stringers. 

I see you speak dutch normaly and you are from Belgium. Same for me 🙂

Good Luck 😉

Hi Freddy,

Do you have earlier experiences with stairs ?

I see some issues on the technical side of the stair . To cover a concrete existing stair it needs to be measured well and fit on the concrete stair. I do this in a cad program where I draw the measured concrete stair top view to see if I have the needed clearances to cover the side and the steps. Also a height check needs to be done to see if the concrete is not going to bump into the steps. 

First of all some technical issues 

30mm penetration is too much . Reduce this to 15mm

risers needs to penetrate the step above around 10mm

the riser needs to be priotised so that it comes behind the steps for screw fixation

also the penetration of the stringers in the newels please set to 15mm and if you use this option of penetration I advise you to use a upper and lower recess of around 25mm to fit the stringers in the newels.

the newel on the stair start ( post 3) should notch in the first step and riser 

Do you need the 140 mm  length beyond the first step on the left stringer ??

What is the reason of having 650mm beyond the last step on top of the stair ?

Do you have an exit on the left of the landing ? Is that correct on width an measurements ?

You have a very high offset above the step nosings . Is that needed or only on the top of the landing ? offset 70mm and the stringer on the landing is 97 mm offset ?

You have no banisters in the railings . Are you going to use something else ?

I would not penetrate the handrails in the newels but set it flush so that you can fix it with screws through the newels

step 5 is not set in the most elegant setup on the newel. Should be set inside the newel or more outside of it depending on the situation you are in but that small part coming out is not looking very well

small problem on step 7 that is cornering the newel . This should be avoided if possible

riser of step 8 is not covered by the stringer. If not possible to notch it in the ewel then the stringer needs to be adapted . The latest version of SD7   7.05 has this possibility. 

steps must also penetrate the newels by 15mm

Hi Freddy,

Attache your file so I can have a look at it . As I understand this is a strairproject to cover a concrete stair ?
