The first thing required for the development of structural framework of the building by design and construction professionals, are structural drawings. For the actual development of structural framework of the building, engineering solutions such as structural steel detailing structural drafting services, precast detailing, rebar detailing, and structural design services such as structural modeling and analysis are enormously essential. When it comes to the development of highly strong structure, structural detailing & drafting are the prime necessities.

During preconstruction, many different types of Structural Drawings are created by construction & design professionals which comprise structural shop/fabrication drawings, chimney drawings, structural connection drawings & erection drawings etc. Throughout the structural drafting process, all these drawings are generated by trained drafters with the close collaboration of structural engineers who keep on directing them. Other technical and highly important drawings which are also made during structural drafting contain roof, truss & joint drawings & foundation plan drawings etc. When it comes to the design & construction of structural framework, the role of structural drafters and detailers cannot be overlooked by engineers, architects, fabricators and contractors etc. They are solely answerable for the detailed development of fabrication drawings, erection drawings detailed technical plans and reports etc., when it comes to the importance of structural detailers.

All types of structural drawings, whether developed by detailers or drafters, must be revised, observed and approved by structural engineers before they are finally optimized by design and construction professionals for the actual development of structural framework.

Fabrication drawings and erection drawings must be made with extreme accuracy among all the above mentioned structural drawings, since they are optimized by design and construction professionals for extremely severe purposes which consist of manufacturing of structural parts & their eventual installation. Quality of those drawings can never ever be negotiated which are utilized by fabricators for manufacturing steel components as it can disturb the entire project very harmfully. Hence drawings formed for the optimization of manufacturers and steel erectors must be studied with high attention by structural services engineers so that no difficulties are confronted by them.

What are Fabrication Drawings?

As compared to Manufacturing Drawings, fabrication drawings are generally used for 1 off’s or per job/project bases.

They are manly used in:

1. Sheet Metal
2. Structural Steel
3. Ballustrading/Handrails
4. Stairs
5. Architectural Steelwork

Manufacturing Drawings are split into 2 types:

1. Part Drawing

These drawings point the part itself that require fabrication for use e.g. by the welder. They also indicate the material and surface finish.

The drawings should comprise the following material. (On the other hand, they should not display further information than is required.) :

• Linear Dimensions including Tolerances
• Material Specification
• Flat patterns including bend lines
• Weld Location & Type
• Weight
• Angular Dimensions including Tolerance

2. Assembly Drawing

As per the complexity, Assembly drawing are often classified into a Top Level Assembly & Sub-Assemblies. This is to give more precision for the full product. Assembly drawings should comprise:

• All parts to be fabricated
• All Sub-Assemblies used within the assembly
• Fixings such as Nuts, Bolts, Washers etc.
• All bought in parts comprising their specific part numbers, supplier or manufacturer
• Cut Lists stating angles & length
• Bill of materials (BOM) showing a full list of all parts
• The drawings should be shown in a way to obviously show how the Fabrication fits together. This should/could contain several views (Top, Plan, Side, Isometric etc.) & Exploded Views
• Additional information that might be essential such as Weight, assembly instructions should also be included if needed.

It is significant that good quality drawings show all the information that is required, but no more than needed. An example is to many dimensions or to many views.

 

What Fabrication Drawings do we offer?

Struccore offers complete set of Fabrication Drawings for wide range of industries. We believe that in order to produce good quality fabrication that will aid an excellent installation on site a certain amount of coordination is required between all parties involved.

We are used to synchronizing with architects, structural engineers and steel manufacturers to create General Assembly Drawings & the subsequent detailed drawings showing connections, holes etc.

Our service prides itself in working closely with all parties involved to ensure any queries get raised and answered prior to fabrication commences.

What information is needed to create Fabrication Drawings?

It depends on the industry involved.

For Structural Steel Fabrication Drawings (including, Ballustrading, Stairs, Architectural Steelwork etc.) we generally work from the Structural Engineers Line Drawings in combination with the Architectural Drawings. We would normally visit site to check any potential clashes.

 

How much do Fabrication Drawings cost?

All are Fabrication Drawings are usually quoted on a fixed price basis as we are normally able to quantify the work easily. All we need is the Structural Engineering Drawings or Architectural Drawings in order to provide a fixed price.

1. The Burj Khalifa stances at 828 meters (2,716.5 feet) tall, rising over Dubai. It’s nearly twice as high as the Empire State Building and three times as high as the Eiffel Tower. Laid end to end, it sections stretch over a quarter of the way round the world.
2. Apart from being the tallest building in the world, Burj Khalifa has six other World Records:

• Highest number of stories in the world,
• Tallest freestanding structure in the world,
• Highest outdoor observation deck in the world,
• Highest occupied floor in the world,
• Tallest service elevator in the world, and
• Elevator with longest travel distance in the world.

3. The total load of aluminum used on Burj Khalifa is comparable to that of five A380 aircraft. The mass of the concrete is the same to 100,000 elephants.
4. Each year 15 million gallons of water are collected sustainably.
5. It has the lengthiest single running elevator, with 140 levels. The elevators are among the fastest in the world and go 10 meters per second.
6. The peak of the sphere of the Burj Khalifa can be seen up to 95 kms far.
7. 12,000 workers were employed on the building per day, at the peak of construction.
8. It took more than 22 million man-hours, 110,000 tons of concrete, and 55,000 tons of steel rebar to complete the giant building.
9. Excavation began in January 2004. The Burj Khalifa finally opened in January 2010, six years later.
10. Burj Khalifa is intended to bear a resemblance to the Hymenocallis flower; the central core appears at the top and concludes in a sculpted spire.
