Top 12 MEP Drawings to Support Design Build Stages

MEP drawings are a great support to the various design-build phases. BIM firms in USA start their designing work with MEP drawings to coordinate through the stages of conceptual, schematic, detail design and construction documentation from LOD 100 to LOD 500. Here we would discuss top MEP drawings that help to collaborate design-build process. However, before that, let’s take a quick look at “What are MEP Drawings?”.

What are MEP Drawings?

  • MEP drawings refer to the mechanical, electrical and plumbing parts of a building. 
  • These building drawings serve as a backbone to the construction project.
  • The MEP drawings enable effective collaboration amongst multiple engineering services. 

Let’s explore a few MEP Drawings used by BIM service providers in USA that help to resolve spatial issues amongst MEP components to be installed in a building.

  • Electrical technical drawings
  • Electrical technical drawings are used to explain the design to electricians and other construction professionals for installing and repairing electrical systems. 
  • Electrical technical drawings provide the visual representation of electrical systems and circuits of a building. 
  • Underground MEP drawings
  • Underground MEP drawings are used for creating underground drainage, groundwork, etc. for subterranean buildings & structures like the museum, galleries, etc.
  • Underground drawings show the underground set-up of a building structure, including mechanical, electrical and plumbing components. 
  • Above coordination drawings
  • Above-ceiling coordination MEP drawings are used for the coordination of the MEP systems above the ceiling.
  • Above ceiling coordination drawings show work within building walls and mechanical spaces. 
  • Composite drawings
  • Composite drawings are used for identifying or eliminating a doubt.
  • Composite MEP drawings graphically illustrate manufacturer’s interfaces, maintenance & clearance for avoiding clashes amongst structural, mechanical and electrical services.
  • Coordinated MEP shop drawings
  • Coordinated MEP shop drawings are used for fabrication, installation, scheduling and other construction activities.
  • These building drawings allow smooth installation of ducts, HVAC and electrical equipment

  • Sheet metal detailing
  • Sheet metal detailing is used to craft the design of buildings, railroads, aerospace and other infrastructural facilities.
  • Sheet metal detail drawings help to shape material designs for various applications like welding, punching, plasma cutting, hydraulic brakes, laser cutting, etc.
  • Pipe fabrication drawings
  • Pipe fabrication drawings are used by MEP designers to stress analysis and produce shop fabrication and spool drawings.
  • Pipe fabrication drawings help to define the process of cutting, welding and bevelling pipe components like pipes, flanges, tees, elbows, etc. as per design documentation. 
  • HVAC & Ductwork drawings
  • HVAC and ductwork drawings are used in different types of buildings like industrial, commercial, residential, educational, etc. 
  • HVAC and ductwork drawings act as a cornerstone for accurate fabrication and installation of components like ducts, plumbing, piping, etc. and detailed building ventilation.
  • Plumbing Drawings
  • Plumbing drawings are used for showing the freshwater system in the building, waste elimination route and gas system.
  • Plumbing drawings help to assess the exact piping layout for installing mechanical units in a smooth way, for instance drainage, garbage disposal, waste carriers, etc.
  • Mechanical piping detailing
  • Mechanical piping detailing is used in construction for conveying fluids and gases from one location to the other.
  • These building drawings help to transport all liquids and gases throughout the building in an industrial process.

  • Mechanical & HVAC detailed drawings
  • Mechanical & HVAC detailed drawings are used to show information about heating, ventilation, air conditioning and transportation around the construction site.
  • These drawings analyze the complex systems of a building by specifying duct layout, mechanical equipment location, diffuser location, cooling system, etc.
  • Equipment Placement Drawings
  • Equipment placement drawings are used in the MEP design build process to explain the details of the equipment placement.
  •  These construction drawings facilitate proper coordination between equipment layout and construction documentation.

Building Drawings for Smooth Execution of Construction Workflow


BIM coordination drawings

The significance of building MEP drawing is marked in the smooth operation of construction workflow. It is to be remembered, that if insufficient information is communicated by the construction drawings, it could lead to a hampered design implementation.

The main aim of the construction drawings, popularly called plans, blueprints, and working drawings show us what is to be built, while the specifications emphasize on materials, installation and quality standards. Architectural, engineering and construction professionals get all dimensions, details, notes and graphic information from the construction drawings. Be it a 3d floor plan, exterior or interior elevation or other details, showing how the buildings would be put together, the construction professionals visualize the entire picture of the construction through BIM coordination drawings. 

Currently, top BIM modeling services are facilitating AEC professionals by providing the right tool and the insight to efficiently plan, design, construct and manage building infrastructure. The engineers are working with building MEP drawings, Heating, Ventilation  & Air Conditioning shop drawings, mechanical fabrication drawings, etc. using Building Information Modeling.

Building MEP Drawings

Let’s now take a look at the different building drawings created through BIM modeling for smooth execution of construction workflow:

  • Building MEP Drawings – MEP shop drawings derived from the 3D BIM model are produced by combining mechanical, electrical and plumbing services. The drawings enable fabrication, manufacturing, installation, assembly, as well as the maintenance of mechanical, electrical and sanitation components of a building. Using top MEP modeling services, parametric modeling and library creation could be accomplished for HVAC and MEP components.
  • BIM Coordination Drawings– Coordination drawings are reproduced through BIM model, showing horizontal and vertical dimensions essential for avoiding interference with structural, framing MEP rough-ins, fire protection, elevators, and other floor and wall penetrations. BIM coordination drawings help various services to coordinate with each other based on design.
  • MEP As Built Drawings – As-built drawings constitute to be a revised set of drawings submitted by a contractor, after completing a project or a specific job. The final as-built drawings encompass all details, as well as the modifications made during the building phase of a project. Though prepared by the contractor, Mechanical, Electrical and Plumbing as built drawingsare more like interpolations done for construction purposes. These help to create effective construction documentation, highlighting changes in red.
  • Engineering Assembly Drawings – Engineering assembly drawings are also supported through Building Information Modeling. The drawings demonstrate the process through which sub-assembly drawings, detailed parts, standard components as well as other specifications assemble in a unified way.
  • HVAC Shop Drawings – Theshop drawing constitutes to be the contractor’s drawn version of the information shown in construction documents. HVAC shop drawings are more detailed compared to construction documents. Shop drawings obtained from the BIM model facilitate in elucidating fabrication or installation of various items to the manufacturer’s production or contractor’s installation crew.
  • Mechanical shop drawings– Accurate mechanical shop drawings produced from the BIM model provide comprehensive information, acting as a cornerstone for accurate fabrication and installation. The drawings facilitate manufacturing, fabrication, installation, assembly and maintenance of mechanical components within a building.
  • Mechanical Fabrication Drawings –  AEC project stakeholders also opt for these drawings from top BIM modeling service providers. The detailed fabrication drawings  are virtual assembly drawing, when a number of items are assembled as a fabrication. The fabrication drawings encompass a list of materials, identifying everything to be used to build up the fabrication.
