A designer is an organisation or individual whose work involves preparing or modifying designs for construction projects, or arranging for, or instructing, others to do this. Designers can be architects, consulting engineers and quantity surveyors, or anyone who specifies and alters designs as part of their work. They can also include others if they carry out design work, such as contractors or tradespeople eg an electrician who designs the layout and specification of an electrical installation or even commercial clients where they become actively involved in designing in relation to their project.
A designer has a strong influence, particularly during the very early planning and design stages of a project. Their decisions can affect the health and safety of not only those contractors and workers carrying out the construction work, but those who use, maintain, repair, clean, refurbish and eventually demolish a building. Decisions such as selecting materials or components of a building can avoid, reduce or control risks involved in constructing a building and maintaining and using it after it is built.
Designer duties apply on all projects, including:
Designer duties apply as soon as they are appointed and when designs which may be used for construction work are started. While most design work is carried out during the pre-construction phase of a project, it is not unusual for it to extend into the construction phase. A designer should agree with whoever has appointed them how long their appointment will last for.
A designer must be able to demonstrate they have the health and safety skills, knowledge and experience (SKE), and where they are an organisation, the organisational capability, to carry out the work they are being appointed for. The level of SKE required should be proportionate to the complexity of the project and the range and nature of the risks involved.
Examples of demonstrating SKE might include:
Examples of demonstrating organisational capability might involve:
