Difference between shop drawings and construction drawings

 

One of the most important first steps in successfully completing a construction, engineering, or architecture project is having shop drawings and construction drawings. Although novices in construction frequently use both terms interchangeably, they serve very different purposes. We at Varmine know how important it is to distinguish these crucial documents in order to make a project efficient, precise, and transparent from the beginning to the end.

Construction Drawings vs Shop Drawings

Project managers, contractors, architects, and engineers will avoid delays, errors, and failed project delivery if they know the difference between shop drawings and construction drawings. While both are crucial, the construction of a building requires them to carry out distinct tasks.

What are Construction Drawings or CD Sets?

Official blueprints used in actual building construction are construction plans, also known as CD sets. These are made by architects and engineers, who are the primary people who make legally binding documents that show that stakeholders have agreed. Plans, elevations, sections, and notes about dimensions, materials, and codes are all included.

What are Shop Drawings?

Construction shop drawings are hand-drawn diagrams that are precise and individualized by manufacturers, fabricators, or contractors. The fabrication, assembly, or installation of specific components, such as heating, ventilation, and air conditioning systems, steel frames, or cabinets, is outlined in shop drawings. When it comes to construction, shop drawing plays a crucial role in breaking down general construction blueprints into specific fabrication steps.

What are the duties of a Structural Engineer

 

Before we turn our attention to their actual job, let’s first establish what a structural engineer actually does.

 Structural engineering is a facet of civil engineering and is a highly specialist role.  Primarily, a structural engineer is concerned with the structural stability of buildings and their main job is to make sure structures can withstand high loads and do not collapse.

 Structural engineers work on all manner of projects, from brand-new buildings or structures that are being constructed to significant renovations that are taking place.

What does a structural engineer do?

As mentioned above, structural engineers specialise in the structure of buildings and they’re concerned with ensuring structures are safe for people to use.  This includes first and foremost ensuring that the structure or building will not collapse and is durable and strong.

But how do structural engineers do this?

Well, the first thing the structural engineers need to do is look over the project's plans to make sure the structure can withstand heavy loads, resist forces, and deal with any bad weather that might be in the area. Safety is the common objective of all of this. Typically, the structural engineers will make drawings that show how this will be done and include important details about the materials that should be used during the construction.

This is not just the case with newly constructed structures or buildings. When renovations are taking place, structural engineers will follow the same or similar procedures. For instance, removing chimney breasts, constructing loft conversions, and installing extensions are just a few examples. Structural engineers will always need to be consulted during these projects to make sure that the changes don't affect the building's structural integrity.

In particular, structural engineers will focus on load-bearing and structural elements such as support beams, frames and joints that are in place to keep a building or structure upright.  A structural engineer's expertise can be sought for advice on electrical systems, sewage systems, fire suppression systems, and other areas in addition to.

Benefits of structural engineers

Building and infrastructure design, analysis, and construction all rely heavily on structural engineers. Their expertise is vital in a wide range of projects and it ensures the safety, stability and durability of structures.

In addition to ensuring that your project complies with all applicable legal and health and safety regulations, hiring a structural engineer has the following additional advantages:

Safety assurance - Structural engineers prioritise safety in their designs, ensuring that structures can withstand various loads including environmental forces and potential hazards.  They always adhere to building codes and standards that guarantee the constructed building meets the necessary safety regulations.

 Optimised design -While it is primarily the role of architects to focus on design and aesthetics, structural engineers can also play their part.  Structural engineers will aim to create efficient and cost-effective designs, optimising the use of materials and resources while meeting project requirements and safety standards.

 Risk mitigation - Whether a building is residential, commercial, or industrial, the safety of its occupants and users is of the utmost importance. By conducting thorough analyses and assessments, structural engineers are able to identify potential risks and challenges early in the design process.  This allows for proactive measures to be taken which will mitigate the risks and prevent significant structural failures.

 Compliance with regulations - All structural engineers are extremely knowledgeable and fully au fait with the relevant local building codes and regulations.  They ensure that the designed structures always comply with these standards, securing the necessary approvals and permits needed for the construction.

How to overcome MEP challenges with BIM

 

The seamless integration of MEP disciplines is crucial to the success of construction projects. BIM contributes to revolutionizing MEP projects by offering solutions based on real-time clash detection.  A better explanation of MEP and how BIM can overcome MEP's difficulties are discussed in this blog.

Assessing the critical challenges of MEP

Traditionally, mechanical, electrical, and plumbing (MEP) systems face numerous obstacles. Multidisciplinary design conflicts and fragmented communication are managed as part of the MEP design throughout the project. This has a strong negative impact on finishing the projects on time and increases the budget.

 The implementation of BIM in MEP design can lead to better coordination.  It can improve the detection of clashes in real time and lead to better spatial design optimization.  This will lead to better efficiency in the entire structure.

1) The case of design clashes across several MEP disciplines

The lack of coordination results in problems with heating, ventilation, plumbing, and fire protection, to name a few MEP design issues. The project experiences delays as a result of these factors as well as time and cost constraints.

2) Lack of cross-team coordination

Coordination and collaboration are essential components of MEP management. It has often been found that communication challenges lead to misinformation being spread.  Maintaining a unified platform is difficult due to this and fragmented data sharing.

3) Not having complete clarity of spatial concept

Lack of spatial awareness is one of the most common issues in mechanical, electrical, and plumbing MEP design. As a result, stakeholders face complex difficulties involving better visualization.  It is extremely difficult to comprehend the intricate spatial relationships among the various MEP design systems.

4) Inefficiency associated with the Data Integration Process

 Ineffective data integration is yet another significant obstacle that comes with MEP. These difficulties are mostly encountered during the merging, managing, and data-sharing processes across various systems.  Traditional methods lead to problems of errors, data silos, and delays, along with suboptimal system designs.

However, it is important to note that oftentimes the challenges are relative.  Since MEP considerations include HVAC (Heating, Ventilation, and Air Conditioning), for instance, a change in any HVAC component can make data integration inefficient. Additionally, it might cause difficulties in design. As a result, it can be said that the challenges are mostly caused by specific internal or external factors.

Contribution of BIM in Managing MEP Challenges

1) Helping in Clash Detection and Resolution

BIM includes clash detection tools in real-time, which are tasked with constantly analyzing 3D models for conflicts.  This is to identify issues between architectural components, structural elements, and MEP systems.

2) Developing a coordinated BIM model

By providing a centralized digital platform, BIM addresses coordination difficulties. It contributes towards outlining a system that can be accessed by all project stakeholders in real-time and get regular updates.  The real-time factor also allows multiple teams to collaborate across various projects simultaneously.

3) Offering 3D Visualization

 One of the challenges associated with MEP design is the need for more spatial understanding that BIM effectively corrects as it offers 3D visualization.  BIM has an intricate system of layouts with a realistic edge.  The ability of architects to plan and make informed decisions is enhanced as a result of this.

4) Improving the process of Data Integration

Architects gain the advantage of having easy access to data at all times thanks to BIM's central system. This is supported by the standardized system of data protocols and formats that are present in BIM software.  This enables simplification in the transfer and exchange of information and improves data integration.
