Building LCA – no significantly different superstructure options

Mat 01 requires multiple significantly different superstructure options at both concept and technical design stage.

Sometimes due to project, cost, or client requirements it is not possible to produce viable options that are significantly different.

In these cases, multiple options are still required in line with the criteria but are not required to meet the definition of significantly different as defined in the methodology.

Regardless of this, design teams must aim to provide meaningfully different design or specification options that still offer viable alternative outcomes for the project, its life cycle impact, and life cycle costing (where this credit is targeted).

Any restrictions which limit the possible options must be justified for the QA submission.
