  6. Conclusion


The designing stage of every construction project is crucial for satisfactory project execution. Every construction drawing has its own drive and a bunch of features. Different design drawings provide a glance into various stages of the construction life cycle. Starting from the foundation drawings to model creation, every building drawing plan is significant to comprehend. If you are from the AEC industry, you must have been acquainted with the concept of shop drawings and as-built drawings.

Let’s have a look at the fundamentals of what is shop drawing and as-built drawing and the difference between these two vital drawings.

What are Shop Drawings?

Every building comprises a set of components, having distinct specifications and measurements. Architectural, structural and mechanical shop drawings are the comprehensive components that facilitate in identifying how they will match with the entire building structure. Further, the shop drawings are created prior to the onset of a construction project.

The Shop Drawings are essential to personify the true image of a construction project. The drawings need the consent and approval of the construction team and are significant for coordination. As soon as the design drawings are approved, the shop drawings refer to how the construction of the project is underway.

Specifications of a Shop Drawing

This signifies the fact that the builders, contractors, workers, and supervisors would retain the specifications of all components of architectural, structural and MEP services beforehand. They are similar to the original building design drawings as conceived by the contractors.

N.B: There is a thin line of difference between construction drawings and shop drawings. Architectural, structural and mechanical shop drawings show the original building plan, whereas the construction drawings are often modified with time. They reflect the amendments a building has experienced whilst the construction process is continuing.

Importance and Benefits of Shop Drawings

The originally designed plan detects the type of material requirements for the construction process. With the production of architectural, structural and MEP drawings, there is no wastage of time or resources in explaining the complete building process to team members.

All these shop drawings, including architectural, structural, and mechanical engineering drawings are self-explanatory, that help contractors understand the dimensions, materials, timelines, process of installation and other details. Hence, the original plan must be arranged before the commencement of the construction process.

What are As-Built Drawings?

Many people often raise the question about – ‘What is As-Built Drawing?’ Architectural, structural, and MEP as-built drawings are created once the project has been completed. They represent how the various architectural, structural and MEP services of the building have been assembled on paper. Several MEP sets of as-builts are necessary for comparing what was the original plan and what could be made towards the project completion. The difference between pre as well as post-construction gets identified by the revised set of as-built drawings. Contractors are also engaged in creating many of the mechanical engineering drawings for project execution. The set of as-built drawings are submitted to clients once the project is completed. They retain all the structural details necessary for installation.

Why do you need as-built drawings?

All as-built drawings for HVAC and other services are significant from a client’s perspective and help them analyze the final product. Several benefits are included for creating as built drawings for HVAC services. They help to install emergency services in a building. In addition, as-built drawings are crucial for conducting refurbishment works in the building. Once the building has been created, the as-built drawings are referenced as shop drawings as they comprise of in-depth information about the whole building structure. This building drawing plan helps in developing contingency plans and defining the emergency exit routes along with the peripherals for future reference for the maintenance team.

As-Built Vs Shop drawing

Difference between shop drawings and as-built drawings

Let’s weigh up the difference in construction technology. The fact of the matter is both design drawings are created by the contractors so when do they differ.

Shop Drawings As-Built Drawings
When are these drawings required?
In a construction project, there are different types of shop drawings such as MEP drawings, spool drawings, architectural drawings, structural steel detail drawing, etc. They undergo changes during the construction lifecycle. The revised set of drawings are the detailed design drawings at the initial stage before the initiation of the construction. As-built drawings record of all the changes the project has gone through project life cycle.
What is the drawing scope of these drawings?
Whereas shop drawings are formed for just a few components of a building like we have separate mechanical drawings, electrical drawings, plumbing drawings which are integrated into MEP drawings for clash coordination As-built drawings are created for the entire construction with precise modules.
How the drawings are subject to alteration?
Shop drawings could be changed in the early stage of designing The as-built drawings, cannot be altered as the buildings are already constructed. However, they can be modified while executing the revamp work and the final compiled drawing prepared by an architect is known as record drawing.
In which projects the drawings are required?
Shop drawings are required for all kind of project irrespective to their size or, type. As builts are more significant for commercial and high-scale projects. As-built drawings are created by the contractors and sub-contractors starting from the red-lined drafts and constitute to be an indispensable part of your construction project


Why hire BIM consultants for construction design drawings?

  • Providing insights into safety:

Using as-built drawing plans, it is easy to undertake process hazard analysis and safety management. Since the building set of plans shows where equipment shut-off valves are situated, you could develop emergency evacuation plans, fix safety equipment, and set up contingency plans around the building perimeter.

  • Facilitating renovations for the future:

Since the as-built drawing process considers only the final erected structure and installed components, they come in handy for any future maintenance work of architectural, structural, mechanical and HVAC services. They facilitate the creation of construction documents as well as shop drawings for old building renovation and ensuring that the retrofits are performed efficiently.

  • Maintenance & operations of structure:

As-built drawings facilitate in maintaining an easy operation of structures, as they are having a clear documented history of the building. They encompass electrical, mechanical as well as plumbing as-built drawings, enabling faster repairs by the maintenance team through quick reference. Without bespoke as-built drawings, it becomes difficult to install, locate and repair components.

How BIM Design Helps in MEP Coordination?

mep services near me , mep drawings

Specifying the plan of diverse building structures in BIM market USA involves a high degree of design coordination amongst mep engineering teams. In present day scenario, one of the prime challenges for top BIM service providers is to avoid overlapping of locations for equipment belonging to diverse building systems. Equipment location conflicts at the construction phase leads to change orders. But the fact is with 2D plan on board Clash detection becomes difficult.

In contrast, while all design engineers work on a virtual reality model of the building, location conflicts are perceived instantly by the software. If two building system components are having overlapping components, the corresponding design teams are notified instantly.

The use of Revit BIM services accelerates the design process, reducing repetition and the amount of time necessary for design review. Furthermore, BIM software is normally adept at calculating material lists, saving valued man-hours. In such a way, a competent BIM engineering company is able to emphasize on designing the best solution without dedicating time to tedious and repetitive tasks. Several projects in the BIM market USA require a process of approval with the Department of Buildings, that is often time consuming. However, if you use BIM software application for MEP drawings, you are able to accelerate the process of project approval for detecting design errors immediately at the pre-construction stage.

Let’s find out Why MEP Engineering Firms Should adopt BIM design ?

Before moving ahead lets understand the transformation brought in by conversion from CAD to BIM. Eventhough the parent of AutCAD MEP and Revit MEP is Autodesk, but still whom to opt for?

Whom to Choose– AutoCAD MEP or Revit MEP:

Child of same parents AutoCAD MEP was an initial version with a strong hold on architectural drafting. Whereas Revit MEP holds the roots of AutoCAD MEP designing capabilities with enhanced services. Mep consultants are able to do better detailed design drawings with Revit mep services.

For a multi-storied building or complex Revit MEP services allows all floor plan designing at one moment whereas in case of AutoCAD MEP floor plan designing of one level can be done at a particular moment.

Discussing ahead are the added benefits of Revit BIM MEP for MEP engineering project

  • Better Estimating For MEP Engineering:

Any design modification leads to changes in material estimation , material procurement. Being an interlinked and interdependent environment change order reflects on quantity take off as well as cost estimation. Even though some estimator rightly said,” Few changes are inevitable and uncontrollable beyond the limits of 5D estimation”. This is very rightly true but 5D estimation and quantity take off through BIM model facilitates the estimators and surveyors to be accurately precise till an extent. This is not the scenario with CAD environment. Change orders constitute to be one of the primary causes of increased project cost.

Based on the structure of the contract, extra cost affects the building owners and the contractors. Augmented change orders lead to missed deadlines, delaying the process of building commissioning. BIM happens to be a powerful project tracker for BIM service providers in USA, throughout the construction project lifecycle, enabling supervision engineers to keep projects within budget and time.

  • 3D Modeling For Design Coordination:

Naviswork 4d simulation results in better mep engineering. The use of Revit BIM services for MEP engineering facilitates in detecting the need for change orders during the design phase, while modifications are executed on a virtual model. It becomes easier to edit a building model faster in 3D BIM, which is considerably cheaper than dismounting and reassembling real installations. Editing the design in the 3d BIM model only costs engineering time, while project modifications encompass material and labor costs.

  • Animation, Walkthrough, Virtual Design and Construction VDC:

 MEP engineering companies with effective scheduling and monitored change order management is able to control the construction cost. This bring smiles not only to estimators and surveyors but also for mep consultants. A VDC model is particularly useful while managing the property and scheduling maintenance operations. This supports a preventive maintenance tactic rather than a volatile approach. BIM modeling helps to fix problems before their occurrence instead of fixing the damage when the components of the building system collapse.

Since the BIM model encompasses data on MEP components for mechanical shop drawing, it gets updated with routine inspections and building system amendments. A virtual model of a building created through BIM facilitates in tracking the key components and schedule their replacements earlier. Engineering work is essential for inspecting the existing property condition and build a consistent virtual model, but once this stage is accomplished the building becomes easy to manage.

Invest in MEP BIM engineering services to reduce building costs for the long run. Remember that a high quality design created through BIM helps to simplify construction, operation and maintenance.

MEP As Built Drawings

MEP As built drawings are a reflection of what the actual construction looks like!


As-Built Drawing | Coordination Drawings

When a construction project begins, blueprints are created to chart a roadmap for construction. However, the final construction usually differs from the original blueprint because the design of the structure undergoes several modifications throughout its lifecycle. MEP As built drawings are created after the completion of the project to provide the client details of the construction that enable him to manage and maintain the constructed structure.

Since as-built drawings play a vital role in maintaining the structure and in case of any modifications or renovations required at a later stage, their quality and accuracy are of great importance.


How to enhance the quality of MEP As built drawings?

Many construction companies follow the process of creating as-built drawings after the construction is completed. The shortcoming of this method is that the MEP As built drawings are inaccurate and not detailed enough. This flaw can only be corrected if data is captured, stored, edited, and distributed throughout the lifecycle of the project. Cloud computing addresses this issue by facilitating the storage of plans and updates. Since cloud storage can be accessed from anywhere at any time, the members of the project team can update details easily in the cloud. Besides, using the cloud from the beginning stages of the project ensures that all design features are stored from the initial stages of the project.

The quality of an MEP As built drawings depends largely on the data it contains. It is recommended that you include as many details as possible in the as-built drawing. There are several tools that help capture data from the initial stages of the project.


Some technologies for capturing data are:

Laser Scanning: This is a survey tool that accurately measures the distance between two points. By using this tool throughout the construction process, relevant data can be collected for the MEP As built drawings.

Building Information Modeling(BIM): Including BIM design and construction data in the As built drawing enhances their quality. These inputs enable visualization of various components and other details to simplify maintenance of the structure.

Connected Construction Data: It is vital to make connected construction data available to the client because any data that goes amiss can cost the owner dearly. Connected construction software such as Autodesk Construction Cloud facilitates collecting critical data such as details of assets, documents, models, etc. Further, these details are organized by the software and so the data can be presented to the client in the form of as-built drawings as soon as the construction is completed.

The accuracy of the as-built drawings can be enhanced by including construction photos that contain GPS data in them.

Any structure undergoes minor or major modifications with time. It is a good idea to create dynamic as-built drawings that can be updated. Providing accessibility to the drawings through the cloud enables various stakeholders to view and update changes as and when required.

Tejjy Inc. is a leading construction company. We provide quality construction to our clients and create accurate MEP As built drawings for the benefit of our clients.
