Utilising Bueno Analytics for Defects Liability Period (DLP)

The Defects Liability Period (DLP) is a critical phase in construction and property management. It provides a defined time frame during which contractors are responsible for rectifying any defects or faults in a newly constructed building. Failure to rectify issues within the DLP can impact the bottom line, and impact a building’s sustainability ratings. 

Bueno, with its advanced building analytics platform, offers a powerful solution for managing DLP effectively, ensuring that defects are promptly identified, tracked, and resolved. This article explains how Bueno can be leveraged during the DLP to optimise defect management, minimise risks, and reduce costs.

What is the DLP

The defects liability period commences upon the practical completion of the construction of a building project. During the DLP, the quality of the work is reviewed to identify defects and ensure all required rectifications and improvements are made. During the DLP, building owners and managers must ensure that all systems and components operate as expected. This involves all aspects of the building’s performance, including HVAC systems, including all other key building operational technologies.  Similar to a warranty period, the DLP serves as a safeguard against construction defects and compliance. It also plays a pivotal role in supporting a business’s economic and sustainability goals.

Bueno’s Approach to DLP Management

Bueno’s platform is designed to gather and analyse data from a wide range of building systems, allowing for comprehensive monitoring during the DLP. Here’s how Bueno can be effectively used for DLP management:

  1. Real-Time Monitoring: Bueno’s platform continuously monitors building systems, collecting data from sensors, meters and metering systems, and Building Management Systems (BMS) and all other building operational technologies. This real-time monitoring enables early detection of anomalies and defects, allowing building owners to identify issues before they escalate, and within the defects liability period.
  2. Advanced Analytics and Alerts: Bueno’s advanced analytics engine analyses the data to identify patterns and trends indicative of defects. The platform generates insights, actions and alerts when anomalies are detected so that building owners and managers can investigate and address the underlying causes without delay.
  3. Detailed Reporting and Documentation: Bueno’s platform offers customisable reporting capabilities. It allows users to create detailed reports on defects, including timestamps, locations, and descriptions of the issues. This documentation is invaluable for streamlining communication with contractors and ensuring accountability during the DLP.
  4. Building Optimisation for Sustainability: Bueno’s energy management, fault detection and diagnostics, and building optimisation modules play a pivotal role in bolstering the sustainability status of businesses. Early detection of a building’s compliance, equipment, usage and faults help minimise emissions promptly. 


Bueno’s platform is a powerful tool for managing the Defects Liability Period in commercial properties and the built environment. By providing exceptional real-time monitoring, advanced analytics, and detailed reporting, Bueno enables building owners and managers to identify and address defects effectively and efficiently. This proactive approach not only streamlines the DLP process but also ensures accountability and reduces operational risks.

Understanding the Challenges of DLP

The Defects Liability Period (DLP) presents several challenges to the business, property managers and contractors. Some of the main challenges include:

  • Financial Risk: During the DLP, the contractor is typically responsible for rectifying any defects at their own cost. 
  • Time Constraints: DLP periods often have strict timelines within which defects must be rectified. Meeting these deadlines can be challenging, particularly if the defects are complex or require extensive work.
  • Disputes and Legal Issues: Disputes may arise between parties regarding the nature of defects, responsibility for rectification, or compliance with contractual obligations. Resolving these disputes can be time-consuming and costly, potentially leading to legal proceedings.
  • Impact on Reputation: Failure to address defects promptly and effectively during the DLP can damage a business’s reputation. 
  • Coordination with Stakeholders: Coordinating efforts between various stakeholders, including clients, subcontractors, and suppliers, to rectify defects efficiently can be challenging. Miscommunication or delays among these parties can prolong the DLP and escalate costs.
  • Documentation and Record-Keeping: Proper reporting, including documentation of defects, their rectification, and any related communications is crucial during the DLP. Inadequate documentation can lead to misunderstandings, disputes, or difficulties in demonstrating compliance with contractual obligations.

The traditional approach of relying on manual inspections and reactive approaches is subpar. This approach can be time-consuming and prone to oversights. 

Bueno’s platform, however, offers a proactive solution. It provides real-time monitoring and data-driven insights to streamline the DLP process and combat challenges. 

Use Case: Streamlining DLP with Bueno

A large commercial property undergoes a major renovation, and the DLP commences upon the construction’s completion. The building owner decides to use Bueno’s platform to manage the DLP and ensure all defects are addressed promptly.

Step 1: Integration for Real-Time Monitoring

Bueno’s platform is integrated with the building’s systems, providing real-time monitoring of HVAC, metering, lighting, refrigeration, and other critical components. The platform continuously collects data, offering a comprehensive view of the building’s performance. 

Step 2: Detection of Anomalies and Defects

As Bueno’s platform analyses the data, it identifies several anomalies indicating potential defects. These include inconsistent temperatures in certain areas, unusual energy consumption patterns, and abnormal HVAC behaviour. Bueno generates alerts for each anomaly, allowing the building owner to take immediate action.

Step 3: Coordinating with Contractors

With detailed reports generated by Bueno, the building owner can communicate effectively with contractors during the DLP. The reports contain all the necessary information to verify defects and discuss corrective measures. This streamlines the defect resolution process and reduces the risk of costly disputes and delays.

Step 4: Ensuring Accountability

Throughout the DLP, Bueno’s platform continues to monitor and document the progress of defect resolution. The building owner can track the status of each defect, ensuring that contractors fulfil their obligations within the defined period. This accountability helps maintain a high standard of quality, ensures that works are completed within the DLP, and reduces the risk of costly rework.
