What is included in quality requirements during project execution?

Quality requirements during project execution focus on ensuring that the project meets its specified goals and standards. Life cycle commissioning is the process that begins with the planning and design phases, continues through construction, and carries on into the operation and maintenance of the building. It encompasses evaluating and validating that all systems perform according to the user's needs and the intended design. This approach helps ensure that quality is maintained throughout the entire lifespan of the project, from initial concept to decommissioning, thus providing a comprehensive framework for quality assurance.

In contrast, while product specifications, environmental assessments, and building techniques are all essential components of a construction project, they do not specifically encompass the broader, more holistic view of quality management as intended in this context. Product specifications pertain more to the characteristics of materials and products rather than the ongoing quality assurance processes. Environmental assessments focus on the project's compliance with environmental regulations and impacts, while building techniques refer to the methods used in construction, rather than the systems and processes that ensure quality. Therefore, life cycle commissioning stands out as the option that best represents the quality requirements throughout the project's execution.
