Definition – Critical value - KBCN1006

Critical value aims to maximise whole life value of the building based on client requirements, and differs from minimising life cycle cost. This is a more specific analysis of how the building's ongoing maintenance and operation can impact business needs. For instance:  

Life Cycle Cost - KBCN0385

Life Cycle Costing (LCC) is a methodology that aims at selecting the optimal option amongst a number of option appraisals. An LCC should therefore consider: This allows project teams and clients to make informed choices about the long term financial implications of different design decisions.

Life cycle cost (LCC)- QS change - KBCN0605

If a Quantity Surveyor (QS) changes during a project, the new QS must demonstrate that subsequent criteria are met in order to gain the 2nd and 3rd credits. While the initial modelling data may not be available, the results and outputs given to the client team will be and can be used to remodel the LCC at the later stages of development using the new QS's data. Provided the new QS can model and determine the best option based on the latest project information, the 2nd and 3rd credits can still be attained. It may be necessary to repeat modelling where there has been a change of QS however, provided the intent of the issue and criteria are met, the credits can still be awarded.

Life cycle cost – Multiple assessments on the same site - KBCN000003

Where there are multiple assessments on a site and a single life cycle cost (LCC) plan will be carried out, it is acceptable to use this plan as evidence provided that the results of the LCC plan can be applied to all of the assessed buildings and therefore may have a positive influence on the material specification of such buildings. Where the design of some assessments differ to the extent that the LCC plan cannot reasonably be applied, a separate LCC plan is necessary to achieve credits for this issue. Where multiple assessments are covered under a single LCC plan, there must be sufficient detail for each building to enable them to be adequately assessed.
