B- 10. “Repair with screening LCA”

*Aspect*		B- 10. “Repair with screening LCA”
*Description*		Repair module covers all corrective, responsive or reactive treatment of a construction product or construction works to return it to a condition in which it can perform its required functional and technical performance. It covers only the partial replacements of components and building parts (in case of failure), and should be distinguished from the replacement module that is related to the complete replacement of component and building parts.

*Provisions*	Repair is optional in the context of screening LCA. For provision and guidance, please refer to the aspect “Repair with complete LCA” of the present document.The reparation procedure refers only to corrective, responsive or reactive actions in response to losses of performances of a building component or building part.Repair is distinguishable from maintenance and replacements by the following aspects [EN 15804]: Maintenance is a planed (proactive) action that maintain components performances whereas Repair is a corrective (reactive) action in response to damage; Replacement covers the complete replacement of a component whereas Repair covers only replacement of sub-components. According to EN 15978, the boundary for repair should include: the production of the repaired part of component and ancillary products; the transportation of the repaired part of component and ancillary products, including production impacts and aspects of any losses of materials during transportation; the repair process of the repaired part of component and ancillary products; waste management of the removed part of the component and of ancillary products; the end of life stage of the removed part of the component and of ancillary products However, in the context of screening LCA, only the production of the replaced component/repaired part may be included.

*Guidance*	Repair is optional in the context of screening LCA and may be neglected in many cases. For provision and guidance, please refer to the aspect “Repair with complete LCA” of the present document.
