Do you need expert advice for construction risk assessment? Trimble Architects offer risk assessments for projects within the construction industry throughout Twickenham and London.

What is Construction Risk Assessment?

A Construction Risk Assessment is a report explaining any health and safety risks that the building project could cause. Before the being written, an assessment of the site must be performed to find all the risks, whether small or large.


The report should include how the workers helping to build may be at risk and how the building's future users may be at risk. It should also include control measures that have been put in place to mitigate the risks. As well as this, fire risk assessments must be completed to allow effective management of fire risks. 

Each risk in the risk assessment report must include the following:

  • Identifying the hazards that may cause injury or harm
  • Think about who may be harmed by the hazard
  • The level of harm the risk could cause
  • What you have put in place to reduce the risk

Why is Construction Risk Assessment Important?

Risk Assessments are a legal requirement for construction projects to ensure workers, users, and the public's safety. Risk assessments make the workers and future users aware of the risks and prevent injury or harm.

If an injury is caused to someone, whether a worker, building user or member of the public and the risk wasn't mentioned in the risk assessment, with no control measures included, then there is a possibility you may face legal action. Furthermore, a new risk assessment would have to be created. 

Additionally, the risk assessment may be used when creating method statements so that the risks involved during the project can be recorded and monitored throughout construction. 


A Site Risk Assessment is made specifically for the site that the building and construction work is occurring. This includes exact measurements, conditions, and the hazards associated with that site only.

This is different from a regular risk assessment, as it is site-specific. You may change regular risk assessments to be site-specific, but you must take all factors into account and ensure it meets the criteria.


There are many health and safety hazards and fire risks for employees involved in construction work. This is why a construction company must carry out the appropriate risk assessments that are required. The risks involved in construction projects can be avoided if the risk assessment form is completed correctly, and project management is successful. This means a full inspection of the site and all the equipment before and after use.

Here are a few of the common risks when carrying out construction work:

  • Unexpected weather conditions (including natural disasters)
  • Damage to equipment or tools (without the knowledge of the employee or the project manager)
  • Conditions of the building site itself
  • Heavy machinery
  • Heights (ladders and boom lifts)
  • Fire risk (machinery or equipment overheating)
  • Employees not wearing the appropriate PPE

What are the Five Steps of Risk Assessment in Construction?

Here at Trimble Architects, based in Twickenham, London, we work hard to ensure all risk assessments are completed accurately and correctly, as we put the health and safety first of our employees and customers first. Here are the five steps that must be followed when doing a risk assessment for a construction project:

Identify the Risks

Firstly, you need to ensure that you have identified and covered all the health and safety risks that could occur with the project you are working on. This might include the height at which the work will be carried out, coming into contact with hazardous materials, general accidents, and even fire. 

Identify Who and How

Next, you must identify those involved in the project, which may be affected by these health and safety risks. You must assess every person involved during the project, which might be at risk and how they might be at risk. This includes your construction workers, other people using the site as well as the general public. 

Evaluate and Prioritise

The third step is to evaluate the information gathered by the previous two. After assessing the project's health and safety risks, who they might affect and how you can decide which risks have the highest priority. Allowing you to provide the specific safety training and equipment necessary so that risks which can be eliminated are done so and those which can not are mitigated. 

Record Findings & Control Measure

When there are five or more employees on-site, it is a legal requirement to conduct and record a health and safety risk assessment in writing. This ensures that you have acknowledged the risks involved in the project you're doing, who they might harm, and which hazards are the highest priority and how you will deal with them. You may include your risk assessment in your method statements; showing that you have fully considered the risks involved and worked them into how you will conduct the project in the future. 

Review the Risk

Given that construction sites are an ever-changing environment, you must ensure that the health and safety risks involved in the project are continuously monitored and updated. This will allow you to conduct thorough and professional management of the project from start to finish, ensuring you meet construction health and safety policy standards while also letting you alter your methods when needed to help those involved in the project conduct safe systems of work.
