What is Load Testing?
Load Testing provides vital information about a structure’s response to applied loadings. Controlled loading is applied statically or dynamically within safe limits, enabling serviceability and ultimate load capacities to be calculated.
At BES Group, we can provide you with a comprehensive Load testing Service, from advising on the best approach to analysing and reporting on the findings. We can arrange and manage the test load, set up and operate the instrumentation, and undertake both dynamic and static load testing.

Key benefits of Load Testing
Risk Management
Load testing can provide valuable information to help you manage technical risks. This information can be used to identify potential problems with your structure and to take steps to mitigate those risks.
Reliability Enhancement
Load testing can provide data to help optimise and improve numerical assessment outcomes. This data can be used to refine numerical models of the structure, which can lead to more accurate assessment outcomes.
Safety Assurance
Our knowledgeable team can assist you with the interpretation of load testing data. We can help you to understand the significance of the data and to make informed decisions about the safety of your structure.

How we work
Load testing is a crucial step in the life cycle of bridges and structures.
We have extensive experience in the assessment of structures, and we know how to help if calculations suggest there is insufficient capacity.
We can carry out:
- Design Verification Testing: We can help you to develop a load testing plan that meets your specific needs.
- Supplementary Testing: We can test existing structures to assess their condition and capacity.
- Proof Load Testing: We can apply controlled loads to structures to verify their strength and performance.
- In-Situ Stress Measurement: We can use a variety of methods to measure the stresses in existing structures.
- Dynamic Load Testing: We can apply dynamic loads to structures to simulate the effects of wind, earthquakes, or other environmental factors.

Why Load Testing?
It involves subjecting the construction to varying levels of stress, simulating real-world conditions. This process helps us identify potential weaknesses, measure the structure’s response to different loads, and ensure that it meets safety standards and regulatory requirements.
Our Load Testing services can:
Refine numerical assessments of bridges and structures
We can provide you with information about the structural stiffness, stress concentrations, and fatigue susceptibility of your structure.
Assess the ability of your structure to withstand required loads
We can apply loads to your structure and measure its response. This information can be used to determine whether your structure has the required strength to withstand the loads it is expected to experience.
Assist with building change of use
We can test your floor slabs to assess their condition and capacity. This information can be used to make informed decisions about maintenance and repair.
Test for dead load stresses in bridges and structures
We can measure the stresses in existing structures using a variety of methods.

Frequently asked questions
What are the main types of Load Testing?
There are three main types of load testing:
Supplementary Load Testing: This type of testing uses loads that are representative of the loads that the structure experiences during its normal operation. Supplementary Load Testing is typically used to verify that the structure can withstand the loads it is designed for.
Proof Load Testing: This type of testing uses higher loads than the structure is expected to experience during its normal operation. Proof Load Testing is typically used to verify that the structure can withstand loads that are beyond its normal operating range.
Compliance Testing: This type of testing is used to verify that the structure complies with a specific set of standards or regulations. Compliance Testing is typically used for bridges and other critical structures.
What can dead load weight testing be used for?
This information can be used to evaluate the dead load stress condition and hence to facilitate a more accurate assessment of capacity available for live loads. We can also measure the damping characteristics of your structure. This information can be used to refine numerical models of your structure, which can lead to more accurate assessment outcomes.
