Understanding the Key Similarities Between Precast and Prefabrication Construction

Precast and prefabrication construction boast many of the same unique benefits — making them both popular alternatives to traditional construction methods. 

Before you begin making any plans for a new building or structure, read our blog to learn about the key similarities between precast and prefabrication construction, and how these methods can successfully provide you with the results you want.

There are three main types of prefabricated systems including 3D, 2D, and hybrid systems. 3D prefab involves two forms known as modules and pods. As their name suggests, these systems are three-dimensional and require very little construction time on-site since they typically arrive almost completely assembled. 

On the other hand, 2D prefab systems involve separate panels and components that are assembled after being delivered to the construction site rather than being assembled before arrival. Finally, hybrid systems use elements of both 3D and 2D prefab processes.

Precast concrete construction is a type of prefabricated construction, more specifically an example of a 2D system, and therefore differs from traditional construction methods in many ways. One of the main differences is that in precast construction, the concrete is poured into molds at an off-site location. 

Then, it is left to be cured until it’s ready for transportation to the final construction site. Precast concrete offers ready-made aesthetic factors such as colors and finishes, and possible insulation, both of which are included before the pieces are shipped to the site. 

There’s a variety of precast concrete types and components for people to choose from depending on the needs of their project and the structure they are building. Some of the most common structures include architectural precast enclosures, structural precast parking garages, and total precast buildings. 

Any precast structure can also feature several components that provide stability, functionality, and design versatility. These include but are not limited to:

• Walls
• Panels
• Beams and columns
• Slabs and planks
• Stairs
  
  
  

When looking at precast and prefabrication construction, it’s not too hard to find similarities. Since precast construction is a type of prefabrication, the two share many overarching benefits, and are often thought of as better alternatives to traditional construction methods. Some of these benefits include:

• Speed of execution and reduced costs. Both methods are known for reducing construction time because a large part of the process is completed off-site. This allows other parts of the project to be started and completed while the precast or prefab components are being built saving time and money in the long run.
• Sustainability. Over the years, research has shown that traditional construction methods hurt the environment. Precast and prefabricated processes both offer a more sustainable construction solution than most traditional methods. They are known for their reduced waste generation, energy efficiency, and low impact on the environment.

Understanding the unique advantages precast and prefab construction offer can be helpful for those who are unsure which option is right for them. Below, we’ve outlined the main reasons people prefer to use precast or prefab construction over traditional methods.

Choosing precast, as an option for prefab construction, typically comes down to the type of structure being built and the materials needed to complete construction. In any type of prefab construction, components are manufactured off-site. This process can involve a variety of materials such as steel, plastic, wood, and iron. 

The components used in precast concrete construction are also manufactured off-site, however, this type of construction involves mixing and pouring a specific type of concrete into reusable molds which come in a variety of shapes and sizes. After it is poured, it is left to cure and settle at an off-site location, typically in a factory or plant.

Precast concrete construction offers strength, durability, and stability, making it a prime choice for structures that need to withstand any type of weather conditions, like natural disasters. Due to the incorporation of rebar and stressed wire cables, precast concrete components offer a better chance of remaining stable in the case of damage or daily wear and tear. This guarantees a longer life expectancy for the structure being built.

Since precast concrete is poured and cured in a controlled environment, it offers higher quality control and faster construction times. Throughout the process, the concrete is tested to ensure its durability. Additionally, this eliminates the risk of inconsistency and delays due to weather conditions and natural elements which often cause complications on the construction site. 

As we mentioned before, any type of prefabricated construction, including precast concrete, involves assembling pre-made components on-site. This process allows more customization,  flexibility, and speed during the manufacturing process and while assembly is occurring on-site.

It is largely believed that precast concrete structures are more standardized and mass-produced, limiting design versatility and customization. However, companies like High Concrete offer a variety of systems and products such as architectural precast, structural precast, and total precast.

Each of these provides the same durability and stability while also allowing flexible designs and versatile aesthetic capabilities. This means precast concrete structures don’t have to all look the same. Colors, finishes, patterns, and veneer panels are all available to create a unique structure.

The many benefits of precast concrete construction are why it has become a popular choice for several industries and markets. As mentioned above, the advantages of precast concrete range from high performance and design possibilities to reduced construction time and labor costs. 

Any type of prefabricated construction is great for lower costs, shorter construction times, sustainability, and flexibility. Precast construction in particular offers peace of mind and structural integrity traditional methods may lack. This makes it the right choice for those who want to invest in unique, long-lasting structures that can be built in record time with low environmental impact.
