Construction Delays and Concurrent Delays

Understanding Construction Delays

Delays can be considered as one of the common events encountered in construction industry, whereby majority of projects including in the Middle East, suffer delays.

Construction Delays and Concurrent Delays

Delays occur due to a plethora of reasons, either attributed to Employers, Contractors/Consultants, local Authorities, other stakeholders, site/project conditions or force majeure. The nature of construction projects being a product to be handed-over years after executing the contract, its complexity and multiplicity of its stakeholders drive such delays.

Delay is one of the fundamental issues that impinge projects due to its negative impact not only on time of delivery but also due to its associated ramifications, additional cost and losses.

Delays are always a center of disputes between the contracting parties due to its negative consequences. For which various techniques for delay analysis have been developed/developing over the years in order to identify the requirements to perform the delay analysis, its suitability, the methodology of analysis and its potential outcomes. However, delays’ issues/disputes are extremely complex, whereby various international standard forms of contracts, professional bodies/institutions and legislators tried to provide guidance and regulation for the same. The matter became more complex and exacerbated when concurrent delays encountered, in simple words, it is delays attributed to both the contractor and the employer running simultaneously, whereby concurrent delay can be considered as one of the utmost complex/controversial features of construction disputes.

Delay can be defined, in simple words, as a delay in performing works’ components/ activities, either a delay to start an activity or a delay to the period required to finish an activity.

Project Management & Construction Delays

Construction delays are a common challenge in the industry, significantly impacting project timelines, budgets, and stakeholder relationships. These delays can arise from various sources, including weather conditions, regulatory issues, material shortages, labor disputes, and changes in project scope. Understanding the nature and causes of these delays is crucial for effective project management and successful project delivery.

One particularly complex aspect of construction delays is concurrent delays. Concurrent delays occur when two or more independent delays happen simultaneously, affecting the project’s completion timeline. These overlapping delays can involve various parties and factors, making it difficult to determine responsibility and assess the impact on the project.

Managing construction delays, especially concurrent delays, requires a comprehensive understanding of project management principles, effective communication, and proactive risk management. By identifying potential delays early and implementing strategies to mitigate their impact, project managers can better navigate the complexities of construction projects and enhance the likelihood of timely and within-budget project completion.

In the context of project management, especially in construction, delays are a critical issue to understand and manage effectively. A delay can be defined simply as a postponement in performing the work components or activities. This postponement can occur in two ways:

1.      Delay to Start an Activity: This occurs when the beginning of a scheduled activity is postponed. For example, if the construction of a building’s foundation is supposed to start on June 1st but doesn’t begin until June 10th, there’s a 10-day delay to the start of that activity.

2.      Delay in Completing an Activity: This happens when the duration required to finish an activity extends beyond the planned schedule. For instance, if laying the foundation was supposed to take 15 days but instead takes 25 days, there’s a 10-day delay in completing that activity.

Understanding these types of delays is crucial for managing the project schedule, resources, and expectations effectively. It’s essential to identify the causes of delays and implement strategies to mitigate them to ensure the project remains on track.

Causes of Construction Delays

Construction projects are complex and multifaceted, often facing numerous challenges that can lead to delays.
