Contractors run embodied carbon assessments to win work and de-risk delivery. Carbon now carries scored marks in tenders, and contractors who table costed reduction options gain an edge no pricing strategy can match. SISK runs its assessments in One Click LCA and benchmarks results across all projects.
Design optimisation can cut embodied carbon far more than material swaps alone. SISK reduced a data hall steel superstructure’s embodied carbon by 55% at neutral cost by redesigning the structure. Tools such as One Click LCA let teams compare design options quickly enough to use them at tender stage.
A whole life carbon assessment quantifies a building’s carbon across its full life, following standards such as the RICS whole life carbon assessment standard. Tenders increasingly require one as a baseline for reduction targets. One Click LCA automates whole life carbon assessments for buildings and infrastructure.
SISK uses One Click LCA to run project LCAs, then feeds the data into an in-house dashboard to compare every live project and report as-built carbon during construction. This supported around 50 tenders, 15 LCAs, and 20 to 30 design optimisation exercises in one year.
