risk managment in construction siteConstruction projects are inherently risky. From start to finish, they involve a lot of moving parts, and many things can go wrong: the weather might not cooperate, the workers might not be able to keep up with demand, or developers could run out of money before completing the project. The best way to mitigate these risks is by preparing for them ahead of time. In this article, we will explore six of the most common risks facing construction projects today.

Cost overruns

Cost overruns are a common, and often costly, risk in construction projects. This can happen for a variety of reasons: Costs are underestimated because they were not adequately planned for. For example, the building might have been designed with fewer rooms than required or without enough power outlets to meet demand.

Costs are overestimated because they were poorly planned for, and this leads to scope creep (more work being added). For example, if you need to build an addition onto your house but don’t want it connected directly to the existing structure but then later realize that this means there’s no way for anyone inside either structure to access each other, you’ve just added another layer of complexity that requires expensive additions like staircases and elevators

Delays in delivery

Delays in the delivery of materials, completion of construction, and completion of design drawings are three common risks that can occur during a construction project. These delays can lead to cost overruns and lost productivity.

Construction projects rely on a steady supply of materials from vendors or manufacturers to keep moving forward with their work. If there are any unexpected delays with deliveries, it can cause serious problems for contractors who may not be able to finish their assigned tasks as quickly as anticipated and may need to hire additional staff to ensure that their projects are completed on time. As a result, they could incur additional costs and lose money in the process. 

Construction projects will always have some degree of delay due to unforeseen events that occur during work. However, if there are significant delays due to factors such as weather or other issues beyond your control, then this increases the risk of cost overruns and project delays.

Defects and poor building quality

A defect is any problem with the construction project that causes it to fail or perform poorly, such as cracks in the walls or floorboards that don’t meet building codes. Defects can occur in any type of construction project, whether you’re building a new home or renovating an existing one.

Some common causes for defects include:

  • Poor planning and design (for example, using materials that aren’t strong enough)
  • Inadequate management during construction (for example, failing to inspect work done by subcontractors)
  • Poor workmanship (for example, installing cabinets incorrectly)
  • Poor-quality materials (for example, using cheap carpeting that won’t stand up to regular use)

Poor building quality can result in significant costs to a construction project and the need for repairs or replacement of parts of the building. It also carries legal risks for both the contractor and the client.

Poor building quality often stems from inadequate planning and design phases of projects, which can be mitigated by engaging experienced designers who know how to get things right the first time around.

Delays in completion

Delays in completion can be caused by many factors, including:

  • Poor communication between the project team and the client. This can lead to misunderstandings about what needs to be done and when it needs to be done.
  • Lack of adequate resources or skilled labour.  
  • Weather conditions such as rain or snowstorms cause delays due to slippery road conditions or other safety issues related directly to weather conditions.
  • Lack of experience with the type of work being carried out. For example, if you’re starting a small construction business and have never done this type of work before but are bidding on jobs that require expertise in this area, then it’s likely that there will be delays because you’ll need to learn how to do things correctly before moving on to the next step.
  • Lack of necessary equipment or tools. If the job requires large machinery, and you don’t have access to this type of equipment, then it may be impossible for you to complete the task promptly.


Construction has many risks that need to be identified and mitigated. A risk is the possibility of something happening that may hurt the quality of a construction project. Risk assessment is a process of identifying, analysing, and evaluating such risks and their impacts.

Risk management involves identifying all potential hazards, assessing their likelihood (likelihood) and severity (impact), planning how teams will respond in case they occur, and implementing measures to control or avoid them if possible. Risk assessment is an ongoing process that should be carried out regularly throughout the life cycle of the project or business, as it helps identify new risks as well as monitor existing ones so that they don’t get out of control.

In this context, construction managers should plan for effectively managing some of the most common risks that could occur during the construction phases of a building, such as:

  • Cost overruns
  • Delays in delivery 
  • Defects 
  • Poor building quality 
  • Delays in completion
