Trends in the construction industry\n\nIn 2024, the construction industry increased focus on sustainability following regulatory changes introduced early in the year, including enhanced energy efficiency requirements for new buildings and overheating mitigation standards. The sector saw greater adoption of low carbon technologies and sustainable materials, prompting a need for specialised skills. Consequently, industry-wide efforts were made to address the skill gap in low carbon construction. These developments have influenced project planning, procurement and costs, reflecting a broader transition toward environmentally responsible building practices (UK GBC, 2025 Trends in Sustainable Solutions for the Built Environment 2024).",

      "content": "The UK construction industry thrives on both JCT and NEC contracts, each offering a distinct pathway to project delivery.

[...] The early warning system is a cornerstone of NEC contracts. Clause 15 places a contractual obligation on both the Project Manager and the Contractor to notify each other as soon as they become aware of any matter that could affect the total cost, delay completion, or impair the performance of the works. This isn't just a suggestion; it triggers a formal process. The Project Manager is then required to call an early warning meeting where the parties discuss ways to avoid or mitigate the problem. The outcomes of these discussions are recorded in an early warning register, creating a clear and transparent audit trail.
