What is Shop Drawings & Importance of Shop Drawings ?

Hello friends, today in this post you will learn about the concept of Shop drawings & also the importance of Shop drawing in BIM.

So, don't skip to read the post completely. After reading the post, you will completely understand the simple concept of the Shop drawings in BIM & other important topics.

So, let's start with these amazing topic...

A shop drawing is a scale drawing which consists of the important information releated to prefabricated components of designed structures along with detailed information.

The information includes in the Shop drawings are associated with the components, assembly of different parts, fabrication, material types, component shape & size, color, installation procedure of various units as well as some other details.

This drawing acts as a design guide for Manufacturers, Fabricators, as well as for Builders also.

As compare the Shop drawings with other construction documents, it provides more detailed information.

In these drawing, we can easily prepare drawings for each individual member for example – column, beam, truss, brace, plate, riser, sill, etc. of a structure.

Along with that, we can also prepare shop 2D drawing for the entire structure within a single sheet in very less time.

We have to first take approvals for the shop 2D drawings that have been prepared for the project from authorized persons such as Architects, Engineers, Contractors or clients. before starting the actual fabrication or construction procedures.

Shop drawings also very helpful in realizing how all the structural as well as steel members will be installed within the structure during the actual construction work on site.

Here are the following information we get from the Shop drawing :

A 2D shop drawing contains – complete dimensions of all parts of a component, manufacturing conventions, fabrication standards & codes. Hence, this drawing helps to the Engineers in understanding the entire fabrication process very clearly.

While actual construction work going on site, it is not possible to follow the original drawing accurately while the structure is developed.

During works, Some changes always occur during construction. These drawing also includes detailed notes related to all the changes or differences that have to be done on the ongoing construction site.

For preparation of Shop drawings, one should have proper knowledge of 2D CAD Drafting Services technology as well as CAD software.

Due to some mistakes in shop drawing, it can make a huge loss in project.

Therefore, These drawings very much helpful in getting high-quality buildings or other structures.

Due to all these reasons, these drawings plays a very big role in reducing project time as well as costs.

Benefits of Shop Drawings :

With the help of Architectural drawings, along with other sketches, professionals can gain a better grasp on the site and may properly develop the entire system.

Also with help of the blueprints, professionals on site gets a clear picture of the whole building process, including supplies as well as some other necessities.

What are the Features of Shop Drawings?

These drawings includes the details of the sections as well as the views along with their specifications, welding/bolting details, fabrication standards, and features.

Also these are designed to make the fabrication as well as the construction processes and procedures easier for on-site construction teams.

By using these blueprints, the site teams get reference to ensure that the fabrication is done correctly.

With the help of Well-designed shop drawings, it is easier in obtaining the architectural approvals as well as can have a significant impact on a project’s profit.

Here are some of specifications included in typical shop drawings are mentioned below :

1.Comparative Data for Engineers as well as also for the Architects,
2.Detailed shop drawings extracted from modeling offer information for the team of architects and engineers, who can easily evaluates, referencing the requirements and drawings.
3. For the designer’s approval, notes referring to any modifications or some changed from the original documentation are also included in the shop desigs, these helps them to enable them to analyze all the adjustments.

Importance of Shop Drawings :

Shop drawings helps to provide an precise layouts to convey the design purpose as well as the concept. It us also very helpful to builder, because it gives the information they need to create, construct, assemble, and integrate all of a building’s components.

It contains all of the essential material as well as the size specifications for assembly, fabrication, and construction.

Structural engineers uses these Shop drawings to ensure that each concrete reinforcing member is made as per the property’s structural integrity, resulting in precise construction.

By using these Shop drawings, the MEP professionals gets a clear picture of how to build ducting, electrical components and pipework on a construction site.

With the help of 3D modeling as well as these shop drawings, it enable to obtain a precise design model, optimize the timetable, perform accurate cost analysis and quantity take-offs, from these, there will be increase production standard, and facilitate handover.

Atlast, the big benefit of Shop drawings are by using it in the AEC sector, It ensure that critical building components are designed, fabricated, and installed correctly.

Details should be included in a shop drawing are mentioned below :

1. Identification of all components with proper tags,
2. Dimensions from x & y coordinates,
3. Interference details with adjacent components,
4. Material and levels tags,
5. Coordinates of components for site surveyor to mark the location on-site
6. Size as well as the location of openings. E.g; Representation of MEP openings in Structural Shop Drawing,
7. Sectional views and Assembly details, important Notes related to any change from the original design,
8. Notes related to any key dimension that has to be verified on-job site before the start of fabrication, assembly and installation,
9. Title block including details like name of project, project no., name of contractors, sub-contractors, general notes, key plans, legends & abbreviations etc.
10. Also, The initial drawing submission date as well as the the dates of the subsequent revision with a short description

Architecture Shop Drawings includes the following Details :

Architecture Plans, Elevation details of Exterior and Interior, Sectional views, Details of Wall, Schedules of materials and Finishes, Utility Plans, Site Plans, Stairs, Kitchen & Toilet Details, etc.

Structure Shop Drawings includes the following details :

Structure floor Plans, Framing Details, Sections of all the Column & Beam , Steel Fabrication details, Foundation Plans, RCC details, Structural Joist Details, etc.

MEP Shop Drawings includes the following details :

Mechanical Plans, Piping layouts, Isometric views, Equipment and Fixture Schedules, Corridor Sections, Lighting and Power plans, Toilet Enlarged Plans, Hanger/Support details, sectional views, etc.
