Role of shop drawings in building construction

There is absolutely no difference between shop drawings and fabrication drawings which are usually created by detailers and drafters for the manufacturing op structural and MEP components. Both structural detailing and MEP detailing are parts of drafting services wherein detailed drawings are generated by detailers which incorporate exclusive fabrication related information within them.



Technical knowledge is highly important when it comes to developing detailed drawings for fabrication purpose. Since all the important structural and MEP components are manufactured on the basis of structural shop drawings and MEP shop drawings their importance for design and construction professionals certainly remains very high. According to a large number of design and construction professionals shop drawings remain the backbone of manufacturing industry since fabricators or manufacturers cannot manufacture building components without their assistance. Without their support manufacturers cannot get accurate information about dimensions, sizes, manufacturing standards, material specifications, welding, bolting and painting related information about MEP and structural components.

The building components which require fabrication include pipes, HVAC ducts, structural columns, joists, trusses and handrail etc and hence detailed information about their sizes, dimensions and material specifications are provided to fabricators through structural/MEP shop drawings. The highly intricate and imperative information is contained in fabrication drawings and hence it is important they are generated by detailers with high accuracy for which they need to follow the specifications provided by structural engineers and MEP engineers.

In short when it comes to the effective manufacturing and installation of MEP and structural components MEP detailing and structural detailing services are important. During detailing process two types of drawings are developed by detailers one is for fabricators and other for installers or erectors. In shop drawings and erection drawings clear instructions are provided to manufacturers and installers respectively in terms of how to manufacture and erect/install the components.


Since shop drawings are utilized for highly indispensable purpose they are effectively reviewed and cross-checked several times by architects and engineers before they are released to manufacturers. In this way shop drawings assist design and construction professionals in the development of high end structural framework and MEP systems.

A brief account on BIM’s expansion over the years

Building Information Modeling has a dramatic history when it comes to its expansion in the landscapes of AEC industry over the years. BIM which is also known as Virtual Design and Construction has a dominant presence in AEC industry because of the fact that is has the potential to realize project outcomes and can control them significantly as per requirement. In short design and construction professionals can attain superior control over project outcomes by analyzing multidiscipline models. Well, Building Information Modeling evolved as a concept some four decades ago but it was not practiced by AEC professionals in the industry at that time. For approximately ten years since it first appeared in the journal, the term ‘BIM’ used to be seen only in research papers. BIM as a technology and a process started to be implemented in construction projects some thirty years ago. So once AEC professionals started using BIM in construction they never looked back to their sluggish performanc...

Tackle positioning issues favorably by sharing coordinates!

Tackling file positioning issues rationally and conveniently remains major problem for Revit users when they link additional file in their model or project. Multiple discrepancies are confronted by Revit users in terms of geometrical positioning of linked files comparative to host model. For example if an MEP engineer working on his model in Revit MEP wants to acquire a thorough understanding of  structural model developed in Revit structure by structural engineer he has to link the model. So when MEP engineer links a structural model in his MEP model, Revit spontaneously displays and alert informing users that linked model does not acquire the same coordinate system as host model. And since they do not share the same coordinate systems, Revit will automatically return back to center-to-center positioning. The alert confronted by users must be cancelled by them at this point of time because positioning associated issues can only be tackled once the file is imported in the mod...

MEP systems provide the momentum to the building

Mechanical, electrical and plumbing systems are incredibly crucial for any sort of building, be it residential, commercial or industrial.   The design for these systems is prepared by MEP modelers who have vast experience in the execution of BIM modeling services.  They develop design for MEP systems in Revit MEP software which is quintessentially dedicated to the design development of MEP systems only. MEP systems consist of HVAC systems, electrical systems and plumbing systems. Detailed explanation of these systems is following  HVAC Systems These systems comprise of heating, ventilation, air conditioning systems. HVAC systems have to be accurate since they are responsible for the circulation of various resources. The design of these systems must be created in a way that they reach to every part of the building where they supposed to reach. They are utilized in all kinds of building projects as well as non building projects such as in...
