Stillads på Nysæter ungdomsskule

Scaffolding for installation of art. i need to have scaffolding erected at Nysæter ungdomskule (in Stord municipality) on the 12th and 13/8 with removal on the 14th. The scaffolding must cover the basement, the first and the second floor indoors, so it must have a working height of 8-9 meters. It is for 1-2 people. There is a distance between the wall and the stairs of 106 cm. So it must be a narrow scaffold. It will be used to install works of art on the wall. a (sax) lift can also be used there, but the problem is that an elevator will take the sax lift to go down into the basement, which can only take 1125 kg. If there is a lift that can go at an angle from the ground floor, that can also be used. Please write what it will cost for the period? Thank you very much! Sara
