How Engineers Provide Plans for Pre-Engineered Steel Buildings

In the world of structural engineering, pre-engineered buildings (PEB) are planned by PEB suppliers/manufacturers, designed with the corresponding stock of raw materials accessible from every source and manufacturing technique that will meet a set of structural and aesthetic concept requirements. In some geographic industries, these structures are all known as Pre-Engineered Metal Buildings (PEMB) or simply Engineered Metal Building (EMB). In EMBs, the amount of pre-engineering is greatly reduced thanks to modern computer software to aid in design.

The basic frame structures of PEBs and PEMBs are I – beams. I-beams are made by forming the letter “I” by welding steel plates together. Then the beams are taken to the construction site to be field-assembled by bolting in the joints and connections forming the building’s overall frame.

Other kinds of frame structure are trusses and mill sections. Choosing the economically optimum form will differ based on factors such as local capabilities and differences in material vs. cost for labour.

For the best accuracy when PEB suppliers design a PEB, engineers consider a lot of points, from bearing points to size and weight of the fabricated parts. In the past, pre-calculated tables were available, thanks to manufacturers, which help engineers in selecting sizes and designs for different elements in the structure. Now in the modern age, these methods are becoming rare thanks to our advancement in computer design software.

PEBs are well adapted to meet a variety of structural needs for varying types of steel buildings. However, the best deal will be realized when standard details are utilized well. PEBs that are designed very well can be much lighter than normal steel reaching up to 30% less in weight. Having less weight will mean less steel used, therefore, big potential savings in the frame structure.

Projects Professionals of Buildings with Manufactured Designs

Responsibilities regarding the erection of metal buildings especially on the aspect of aesthetics, durability, and dimensions lay on the hands of the project architect also known as the Architect of Record. When working on a PEB as a project, the architect takes on conditions of the manufacturer’s offerings on the final product which include color, material, structure, etc. He is also responsible for ensuring the manufactured product to meet the building code requirements and requirements of the customer.

Several jurisdictions acknowledge the differences between the project engineer also known as the Engineer of Record and the subcontract engineer of the manufacturer itself also called the specialty engineer. The primary differences between both of these engineers regarding a project are the limits or obligation and responsibility on the finished product.

The Engineer of Record holds responsible the specifications of the layout parameters of the product and having to ensure that the element and construction styles of others worldwide are in congruent to the final product.

The specialty engineer’s responsibility is to layout the elements of the metal building of which the manufacturers are obligated to give based on a contract and to handle communication of assembly processes, layout assumptions and reports, to the length that the layout relies on other’s work like the Engineer of Record. The manufacturer makes an engineered product. But, they do not really provide services relating to engineering to the project.
