Shop Drawings through BIM
BIM is the buzzword in today’s construction arena. It has almost captured 45% of the industry and is growing fast. Building Information Modeling offers complete building design solutions including BIM Modelling, BIM coordination, Shop Drawings etc. The intervention of virtual construction modeling aids in quick execution of projects, reduction in overall project cost and increase in project efficiency.
We can use the same 3d model to work with for all the construction phases and retain it till the end. One of the construction phases is Shop Drawing creation. Shop drawings are an extremely detailed and integral part of the construction phase. These drawings consist of all the details that need to be constructed or installed in a building. BIM shop drawings are extracted from a 3D geometry and provide all necessary information required in onsite construction. MEP Installation Drawings, shop Drawings or Construction Drawings are critical and determine the success or failure of a project. BIM Engineers or Architects with immaculate field experience can only work on this particular scope. In this blog, we will talk about the most critical 2D drawings and layouts from BIM that are extremely important for construction.
Architectural Construction Drawings: Architectural Construction Drawings can be extracted from a BIM Model with all the construction details. These drawings are also known as “BIM construction Drawings” since they are extracted from a BIM Model. The best part about utilizing BIM for working drawings, presentation drawings or Architectural shop drawings is that all the detailing part can be done in the modeling stage and they reflect in 2D drawings. In case of any modifications or last-minute changes, they can be made in the model in 3D view and reflects in 2D. Working with virtual construction modeling promises accurate results with speedy execution.
Architectural Construction Drawings is actually a bridge between the design stage and construction stage. The level of detailing factor represents whether the drawings are design drawings, working drawings or detailed construction drawings. With BIM we can also create construction drawings with actual detail of any component with all manufacturing detail, real time asset information, shape, assemblies etc. When we work on BIM Construction drawings level of detailing taken into consideration is LOD 400. Architects and on site contractors require the Architectural shop drawings that are detailed with all information pertaining to the building.
Working Drawings: Working drawings usually do not contain details like BIM construction drawings but are an intrinsic part of the design and development stage. Architectural working drawings are less detailed than construction drawings but more detailed than presentation drawings. These drawings basically work well for Architects willing to present the design drawings to client or builder.
MEP Shop Drawings
Usually Mechanical Shop Drawings and Installation drawings are pre-requisites for any MEP contractor to pursue construction. It is important to deliver MEP shop drawings which are standardized, coordinated and detailed according to design codes applicable in each location. HVAC, Electrical and Plumbing coordination is critical for construction. If the drawings are not coordinated, it may lead to severe implications in terms of cost and delay in construction. With the help of Building Information Modeling, we can check for interferences and resolve them collaboratively prior to extracting MEP shop drawings. BIM’s intervention in the generation of MEP Installation Drawings has certainly made the construction projects better in terms of speed and accuracy.
Structural Fabrication Drawings
Structural shop drawings or fabrication drawings are detailed representation of the structural details in any building. We can create structural BIM Model and extract shop drawings. We can create structural fabrications drawings for industrial structures and provide the detailed drawings for installation of fabricated components. The set of drawings available in the structural shop drawing set or BIM structural drawing sets are GA drawings, Erection Plan, Assembly Drawings, Part and Bolt list, .NC drawings etc. These drawings can be for residential, commercial or industrial structures.
Conclusion:
In this article we tried to throw some light on the kind of drawings that can be extracted using Building Information Modeling. However these advantages can be achieved when we have a competent team of BIM Architects and Engineers available to execute the projects. It is important to find a competent BIM companies or staff that help you with this work. In case you want to test the waters and then hire internally, there are many companies out there who will be glad to assist with these services.
