Sub-dividing the assessment procedure into stages enables flexibility to different procurement routes and improved information storage and handling.
The key BRE-SLAM assessment stages are:
| Assessment of the Client's Requirements |
| This ensures that the client has identified their requirements for the building or structure. These requirements will form the basis of a client brief, a vital document in service life assessment. |
| Assessment of the Client Brief |
| This ensures that the service life is specified, understood and agreed by the client and the design/construction team. The client brief is the document against which later stages of the assessment are benchmarked. |
| Assessment of the Conceptual Design |
| This identifies the broad service life issues connected with the construction project before the detailed design process begins. Often decisions taken at this conceptual stage can have a significant impact on the service life but are difficult to change once the detailed design process begins, for example, the orientation of a building or the choice of pitch or flat roofing. |
| Assessment of the Detailed Design |
| This ensures that the specified service life requirements of the building or structure are fulfilled. It includes the assessing the materials specified and facilitates the development of a life-care plan for the building. |
| Assessment of the Life-care Plan |
| This ensures the life-care plan is in accordance with the client's requirements and that this plan is understood and usable by the client. This assessment offers and opportunity for the design/construction team to highlight any life-care requirements that are often overlooked by the clients and users of the building. |
| Assessment of Construction |
| This ensures that the construction phase is reasonably planned such that areas critical to service life can be (and have been) appropriately constructed. |
| Assessment of Operation and Life-care |
| This ensures that the requirements of the life-care plan are being fulfilled and that service life is not impaired by other works, such as refurbishment. |
