CONCRETE CALCULATOR

Concrete is widely used in commercial construction, particularly in London and other major global cities. This is because, not only is concrete renowned for its strength and durability, but it also represents a fantastic cost effectiveness, and a completely flexible, versatile material.
As a result, concrete features as the primary material in construction projects including everything from housing developments to retail centres, and multi-level office blocks, to industrial complexes.
At iMix Concrete, we specialise in the supply of premium quality, ready-mix concrete, trusted by commercial projects across London and the surrounding areas.
In this article, our team have shared their insights into how to estimate the amount of concrete required for commercial development projects.
How to determine the concrete required for a commercial development
Correctly estimating the amount of concrete that a project requires is critical, not only for budgeting, but also for ensuring accurate planning and timely workflows.
The volume of concrete that is required for a commercial development can vary, based on a number of key qualities:
- The type of building
- The size of the building (including the number of floors, if multi-storey)
- The design for the building’s foundations (whether they will be shallow or deep)
- The load requirements for the building
- The construction methods being used (for example, either in-situ casting or using precast elements)

How concrete can be used in a commercial project
1. Foundations
The foundation design used for a commercial project can either be:
- Shallow – Commonly used for smaller commercial buildings, such as smaller offices or retail units. Usually, shallow foundations require hundreds of cubic metres of concrete.
- Deep – Used in larger commercial buildings, particularly multi-storey buildings. Typically, deep foundations can require thousands of cubic metres of concrete.
2. Floors and structural slabs
Concrete floor slabs are widely used in commercial spaces, particularly large open spaces. Then, in some multi-storey buildings, concrete floor slabs feature on every level.
A concrete floor slab is usually between 150-300mm thick (depending on load requirements).
3. Structural elements
The concrete structural features that are typically used in commercial projects include:
- Columns
- Beams
- Shear walls
- Cores
These significantly increase the overall concrete consumption of a build.
4. Construction method
- In-situ concrete – This involves pouring the concrete and setting it on site. This approach provides greater flexibility.
- Precast concrete – Involves pre-casting the concrete elements that are required in advance, and then bringing them to the site. This is an effective way to make the project run more efficiently.

Standard concrete volume estimates
Although these standard figures will vary based on the specific project’s context, concrete estimates for a typical commercial project are as follows.
| Commercial Project Type | Estimated Concrete Required |
| Residential Developments (average size) | 2,000 – 10,000 m³ |
| Shopping Centres | 10,000 – 50,000 m³ |
| Multi-storey Offices | 5,000 – 20,000 m³ |
| Multi-use Complexes | 15,000 – 60,000 m³ |
