Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Dear Prasad,

The basic idea is that you have to understand the structural system and start from the Anchors, Main Members, Bracing, Secondary Members, then the cladding. And finally touch up and handing over.

For the Fins, these are different shapes of solar blades ranging from 10cm to 100cm in width. They can come as 1 or two parts. What you need to do first is install the brackets in the right orientation as per drawings, then you install the Fin. The thing you need to watch out for is the quality of the work, they have to be watertight and they should not accumulate dust an their surfaces.

The Spider System is a structural system. You need to install the brackets with anchors, then you need to install the Main Members, the is followed by the bracing and the secondary members, then you install the Glass panels. Finally you apply the mastic and make it water tights.

The Dot Point is a new term. I can’t offer advice unless you tell me specifically what it is composed of.

I would recommend that you visit the website of the major fabricator/ system that you are using. They must have a propress website that you can download all the technical information. Unless you are working with a secondary supplier in the market. In this case, I would recommend that you enter the websites of Major Suppliers in your area or worldwide and get to learn the details. All the information about any system they are using is free online or can be ordered easily. This is part of their marketing.

With kinds regards,

Samer

Hi Prasad

Sorry but I have never dealt with any of these systems.

You need to check the method statements of the cladding firms.

Otherwise try Google.

Best regards

Dear Mike,

I understand what you are saying. If you have a big project, then you need the time and can work on standard sizes taking into consideration that the Construction must be within tolerance.

On smaller projects, the requirements can be accommodated within 30-60 days of fabrication. It is must cheaper to wait until the openings are complete, then you take the actual dimensions.

Yes, on small project we wait, on large projects fabrication proceeds as per approved drawings.

With kind regards,

Samer

Hi Samer

I have worked on cladding projects where there is enough tolerance designed into the secondary supports and bracketry for the cladding to track the vertical progress of the structure with a 3 level lag - it even works on insitu concrete.

The onus is on the structure contractor to work within the contracted tolerances and delays occur when he gets it wrong.

With other systems as you describe you have to complete the structure before measuring up the bracketry.

Best regards

Dear Prasad,

I will start with the site survey, and if Lucas has any info he can elaborate more:

Site Survey. The Contractor will ask the Specialist (Cladding Company) to complete the works. They agree on the Issue for Construction Drawings and these drawings go into the Cladding supplier system.

The first thing the cladding supplier has to do it to get the Shop drawings approved. To do that, they need to get the exact dimensions from site. To get the exact dimensions, they need a professional surveyor to get the dimensions, elevations and levels for each opening, canopy, fins, etc that is within their scope of work.

The professional surveyor submits their report to the Cladding Company (maybe it is made within the company) and they use the date in preparing the shop drawings.

I always recommend verification at each step. Therefore, I would like for the Supervising Engineer to verify the Survey report in order to make sure that the data used for the preparation of the shop drawings is correct.

With kind regards,

Samer

Dear Prasad,

I have not done a full cladding system like the one that you described. But I would recommend that you sit down with the installer and determine the steps that they will take to complete the installation.

Basically, these are the general steps:

1. Survey for all the elevations.
2. Submit survey for supervising engineer approval
3. Shop drawings preparation
4. Shop drawings approval
5. Material ordering
6. Material manufacturing
7. Material dispatch to site
8. Installation of Brackets/spiders
9. Installation of Mullions
10. Bracing installation
11. Glass installation
12. Mastic and touch up
13. Inpection and handing over

You will need to repeat steps 8-13 for all floors.

With kind regards,

Samer

Dear Prasad,

Can you give us a small description of the project. It depends on the size and complexity.

The basic steps should be the same:

1. Survery- setting out.
2. Bracket installation / Spider
3. Fin Installation / Glass fitup
4. Touch up
5. Inspection and handing over.

With kind regards,

Samer

Dear Johnny,

If you give us more details about the project and the systems that you are using, we can assist more in compiling the list of activities for your use.

Hi Samer

Another brilliant list but we need to consider the interface with the structure.

Some systems require that the top level is reached before the brackets can be lined and leveled.

Others allow the brackets to creep up three storeys below followed by the cladding.

Sometimes there is more than one testing operation at different stages.

We have the makings of a good team here.

The best advice for Johnny is to get a method statement from the cladding contractor and follow that.

Best regards

Mike Testro

Hi Johnny

There are so many different types of installation available for cladding systems that a single simple answer is not possible.

Can you be more specific as to what system you are using.

Best regards
