Stripping out ducting. Building rennovations

Zak here from Cape Town, South Africa!

So this is today's work: Stripping out ducting that is connected to the HVAC system in this shop.

In the picture above you can see the gree scaffolding. That is going to become a wall and the new outside of the store. The rest is being demolished.

So we have to remove the ducting without damaging the ducting that will remain which is still a massive system.

There is also call to re-use some of this ducting in another shop in the same mall so we have to take out a portion of the ducting without damaging it.

Below is a photoreel of some of the sights on site. With careful supervision, the guys built this scaffolding the proper way and it is sturdy and reliable!

Tie Bars and Plan Braces should always be used. Knee Braces are installed in opposite corners.

Here is a line of single joints taken out on the "inside" of the new shop.

One of the removed ducts. This one measure 600x600, quite large. But nothing compared to what we stripped out two weeks ago in another store.

All of that ducting must go out... this means that pile of sand needs to move too!

This is a 600 x 400 duct. The smaller size ducts towards the ends of the system.

This shows a view of the inside of the shop, from far away from the section where we are working. This is a truly massive store.

All of this has to do with the casting of the new pillars that are going to be part of the new wall for this store.

Here are our guys removing another link of ducting. This ducting is fastened to one another with 4 bolts, one in each corner while there is a duct clamp installed in the center of each flange. Generally you need a No. 13 Spanner to get that job done... and this is also the spanner that goes missing the most. I know that mine is currently missing and I am rather annoyed at that!

You might notice that there is a rope attached to the ducting. This is so the guys can lower the duct down instead of passing it - which would be dangerous for the people working below, or throwing it down - which would damage the ducting that we intent to re-use.

Currently there is a massive hole torn into the wall. This is to allow vehicles and machines to drive in and out of the building.

There is also a bunch of other equipment that is standing in the way of our access. We will need to negotiate with them tomorrow to see if these things can be moved.

However, if all goes well, we should finish with this job tomorrow.

We luckily quoted to do this job in four days and we started today. Likely this means that we would finish the job using half the time on the quote! A good profit on this job!

Thank you for reading.

Cheers!
