We continue our “Lessons learned” series. Can you spot the snake in the grass, in the following problem?
There are a million gotchas when detailing, which can trip up even the most experienced detailer. Here’s an issue that snagged us. Hopefully you can learn from our cock-up.
Generally, roof sheets are provided by the roof sheet erectors. But they want supports for the roof sheets from steel which given by steel detailers. Structural engineers will not give details for roof supports all the time. Sometimes they will miss it, or they will leave it to detailers. If that occurs, detailers must come with their own design (but, must get approval by struct engineers).
There are purlins in this picture to support the roof sheets. Detailers did their job as per structural documents. So that detailer’s work is finished. Pop quiz: the detailer’s work is finished, right?
If you think like this, then you are wrong. Have a deep look into that: there are no supports for roof sheets around the perimeter of the roof.
So at this situation detailers must check whether there is support for roof sheets at every ends. If there is any conflict found, you must need to provide steel for roof perimeter supports. Refer below images.
Here are the steels that are provided by our detailers. This can prevent site issues. Rectification on site is extremely costly, and worse, it’s extremely time consuming. You can avoid nasty delays by some carefully investigating the drawings, and avoiding dangerous pitfalls early on.
