The Use of G.I. & B.I. Pipes Scaffold

When is G.I. and B.I. Pipe use?

Normally in the Philippines, Frames Scaffolds (A-Frame, H-Frame, E-Frame) are used instead of Pipes Scaffold. It is because it is cheaper and easily assembled. Even common "carpintero" can assemble it, allowing owners save on labor expense. Erecting pipe scaffolds requires skilled scaffolders.
On the other hand, international standard, specifically use pipes scaffolds rather than frames scaffold for high rise buildings.

Scaffold G.I. (Galvanized Iron) Pipes comes in Sched. 20 or Sched. 40 thickness but engineers recommend to use schedule 40 pipes because of its strength to withstand heavier load.
Specifications usually are the following:

Scaffold Pipe G.I. 1 1/2" diameter x 6m Sched. 40
 also comes in (1m to 5m cut).

Shoring Jacks for Formworks

Shoring Jack Scaffold

Shoring Jack is used during pouring cement mix on slabs as support (pangtukod) to the formworks. Usually it is made of high quality B.I. material and can extend up to 5m or more. In our company, we have the following sizes and specifications:

1.70 x 1.50m ( up to 3.10m full extension)
2.00 x 2.00m (up to 3.8m full extension)
2.00 x 3.00m (up to 4.80m full extension)
3.00 x 3.00m (up to 5.60m full extension)

In the Philippines, house building usually uses the 3.10m and 3.80m because average ceiling height is only 3m. Here are some images of shoring jacks.

 

We recommend that for every square meter of area (slab) to support, use 1 piece of shoring jack. So, for example, for 100sqm. of area for slab, use 100pcs. of shoring jack.

 What Type of Scaffoldings will be needed for your Construction Works? 

Why use scaffolding in your construction works? What are the advantages of using pipe and frame scaffolds over using coco lumber?
In the Philippines, scaffold pipes have been introduced already for decades now but they are not as popular as using coco lumbers? Even in some urban areas in Manila, I can still see some buildings constructed as coco lumbers for formworks. Maybe, there are presumptions that pipe scaffolds are to be use only for high rise buildings. Or perhaps they think that they can save several pesos by using coco lumber?

But heck no! You're just multiplying your expenses. Why? Here are the advantages of using scaffold frames:

1. Easy to install/dismantle, no need to spend more time hammering all those nails, therefore you will be reducing the labor cost.
2. It is environment friendly! No need to cut more coconut trees for lumber.
3. Still reusable for other projects if you buy or you can just rent.
4. Safe to use as long as you meet the specs of your project and your supplier do not use China pipes.


There are different types of scaffolding that you may choose for your construction needs; it depends on the area and the type of construction work that will be done. Standard types of scaffolding are the following:

1. A-Type Frame

This is also called the "walk through" scaffolding. Workers can easily walk through the center without
hindrance/obstacles.  

Standard size for A-frame is 1.70m (height) x 1.20m (width) x 1.80m (length), usually made of Black Iron metal pipes painted or galvanized pipes.

 2. H-Frame

This is one of the most commonly used frame scaffolds, basically because this is cheaper than A-Type Frame because its design is simple to fabricate, no need to bend the pipes.

                          (1 set of H-Frame consist of 2pcs frame, 2 pcs crossbrace, 4pcs joint pins)



Standard size for H-frames are 1.70m (height) x 1.20m (width) x 1.80m (length) also available in Black Iron and galvanized pipes.

3. End Frame

End Frame is a shorter version of H-frame. This is usually used to connect in order to achieve the height requirements of the project. Example: Ceiling height in the Philippines is usually 3m tall(standard height). And if we are going to do a slab and use h-frames scaffolds,you will need to use an end frame. It is because, standard height of h-frame is 1.7m, we will add a 1.2m e-frame to achieve the requirement. Then, we will just add adjustable base jack or u-head to finally reach the exact height of the ceiling.

Available e-frame sizes:

1. 1.2m x 1.2m
2. 0.90m x 1.2m

Width of the scaffolds will depend on the sizes of the cross brace.
