THE IMPACT OF ERRORS, AND CHANGES ON THE PROCESS OF STRUCTURAL STEEL DETAILING

 

Because of changes some problems we face   in the construction of steel structural detailing, .These changes can occur from sometimes some errors, mistakes, and sometimes if the client's desires change. this can affect.  The structural design and geometry. There are four primary events- engineering, detailing, fabrication, and erection.

Engineering-  The best time to discover an error basically the change is usually during the construction of steel design. from these chnages including the placement of new steel not anticipated, this change might be already in the model, and any one of these changes may impact engineering. luckily, the impact is usually a little bit in the terms of time and cost because the changes are known and we implemented for the long term before fabrication.

Detailing: some times minor changes during the phase of detailing may have a large impact on the project, all depending upon the nature of the change. Sometimes the changes might be important but has little impact. This all depends on the type and timing of changes. to understand by dividing the detailing activities into four parts, details drawing, submittals erection drawing, and bill of materials.

If the changes initially occur.it is called an advanced bill. the new or replaced steel caused

sometimes the newly replaced part is not available in the purchased order. therefore the changed steel needs to be purchased separately, material handling and storage is a huge labor expense for fabricators.

Fabrication: Now the detailer sends the drawing to the fabricator's office to process. in this process includes we check the drawing to ensure all pieces are detailed, make a template, and then decide which piece will be fabricated first.

if a change comes in between fabrication it will inherently impact both detailing and fabrication.

then the impact is very high very half of the prioject is completed

Erection : changes that are occurred during erection are the most costly and expensive.

After changes were made the erection of the assembly is complete now requires the big cranes for the move or may require some additional rental equipment.

so at last Axtella structure's main focus is that we provide accurate drawings at once. No rectification is needed again and again.
