Are you planning a warehouse, factory, or any industrial structure? Well, one thing is sure, the cost of the PEB structure project will be one of the first things that pops up in your mind.
It sounds logical at first. You may think there is a simple formula or a basic principle behind it, just a fixed cost per square foot, something easy to calculate and move forward with.
But it is not as simple as it sounds.
You can see two projects of similar sizes, but the cost of one might be much higher than the cost of the other project.
It is not because of the vendor or the cost of materials at the time of project planning. It is simply because of the small decisions taken during the project.
The fact of the matter is that the cost of a PEB Structure project is based on a combination of many factors. If you know all of them, it will be easy to understand why it is costing what it is costing.
So, here are all the factors one by one.
Project Size and Built-Up Area
The size of your project is one of the first things that affects the cost of the project. As the built-up area of the project increases, the cost of the project will also increase. But at the same time, the cost per square foot of the project will actually come down.
This is because there are many costs associated with the project, but they are more or less fixed costs, such as:
- Costs of designing
- Costs of transportation
- Costs of mobilization, etc.
Building Dimensions and Design Complexity
PEB structures do not have simple designs. Some buildings have simple designs. For instance, a rectangular design with standard height and roof type. Designing, manufacturing, and installing these buildings is simple.
However, when the design becomes complicated, the cost also becomes higher.
For example, a clear span design needs stronger steel sections. If the height of the building is increased, it also increases the load. If the design includes mezzanine floors, the cost also increases.
The shape of the roof of the PEB structure also impacts the cost. Simple designs are cost-effective. Customised designs, though beneficial, also incur a higher cost.
Type and Grade of Steel Used
Steel forms the core of any PEB structure. Thus, it is natural that it contributes a major portion of the cost of the structure.
The quality of steel used impacts the cost of the structure. Better quality steel provides higher strength, durability, and resistance. However, it also incurs a higher cost.
The thickness of the steel sections also impacts the cost. Thicker sections have the capacity to bear higher loads. Customised steel sections also incur a higher cost.
Environmental conditions
Environmental conditions also affect the costs of PEB structures.
- A building constructed in an open area or near the sea will need to withstand greater wind loads.
- A building in an area prone to earthquakes needs to be designed to withstand earthquakes.
All these conditions are considered when designing the structure. A stronger structure needs more steel and more engineering, which is more costly.
Foundation and Site Conditions
Even though it is a PEB structure with a steel framework, the foundation is also important.
The site conditions, specifically the quality of the soil, play an important role in the foundation and it affects the costs.
- If the quality of the soil is good, the foundation is easy and inexpensive.
- If the quality is poor, more work is involved in the foundation, which is more costly.
This may involve more excavation and more concrete used in the foundation.
Application of the PEB Structure
The usage of the structure changes the cost entirely.
- A warehouse is generally meant to store goods. The design is usually space optimisation-oriented.
- A factory may require the structure to be highly load-resistant.
- A cold storage structure requires temperature maintenance.
- Commercial structures may require aesthetic appeal.
Thus, the cost of the same PEB structure varies depending on the usage.
Roofing, Cladding, and Insulation
The outer layer of the structure is another factor to be considered.
Metal sheets are the cheapest option. These sheets can be used as the outer layer of the structure. However, when the structure requires insulation, the cost increases.
PUF or EPS panels can be used. These panels can be used to maintain temperature.
Accessories and Additional Features
Most times, such features are added to the project without the knowledge of the cost implications.
These features include the installation of skylights to allow natural lighting, ventilators to allow natural ventilation, doors and windows, installation of gutters to allow the free flow of water, etc.
All these features may be individually inexpensive to implement. However, when all the features are considered together, the cost implications can be substantial.
Transportation and Logistics
The cost implications of the distance between the fabrication unit and the project site are usually underestimated. A long distance would imply a higher cost of fuel to transport the project to the site. In addition to the cost of fuel, the logistics of moving the project to the site can be cumbersome.
Project Timeline
Time is another factor that can have a direct impact on the cost implications of the project.
However, if there is scope for increasing the project time, then the project can be planned more efficiently. The materials can be procured at a lower rate, and the labour can be managed more smoothly.
However, if the project needs to be completed urgently, then the production time, scheduling, and overtime all add up to a higher project cost.
Conclusion
Aforementioned pointers are some of the factors that affect the costs of any PEB Structure. Apart from them, the customisation or standard design, the location, vendor also have an impact on the project. For example, the standard design of PEB structures is generally more cost-efficient because they have a proven design and require minimal engineering costs.
