Lifecycle planner — the 10-year operational window
The decade-long planning view that takes a system from handover through expansion and into retrofit / refresh.
A building system lives for a decade or more. The lifecycle planner is the view that takes the system from handover (year zero) through expansion (years one to four) and into retrofit / refresh (years five to ten). The planner does not predict the future; it documents the decision points where the next reinvestment is expected, so the client can budget against them. The discipline is the decision point — when is the battery string due, when is the BMS supervisory layer due for a major upgrade, when does the addressable fire panel reach end-of-line. Surfacing these in year zero is what distinguishes a 7-stage handover from a 7-stage handover plus a lifecycle plan.
lifecycle
Year zero — stabilisation
First-year stabilisation — snag list closure, trend baseline, first AMC cycle.
Duration · 12 months
lifecycle
Years one–four — expansion & incremental upgrade
The incremental expansion window — added zones, added cameras, added scenes. Each expansion produces a mini-commissioning.
Duration · Across years 1–4
lifecycle
Year five — mid-life review
A formal review of the system against the original requirements pack and the current operational reality.
Duration · 1–3 months
lifecycle
Years six–ten — refresh or retrofit
Roll the system through a refresh (firmware, point devices, ballasts) or a retrofit (panel, supervisory layer, BESS).
Duration · Across years 6–10

/ Lifecycle principles
The principles that govern the lifecycle view
maintenance
Preventive maintenance over reactive response
An AMC measured by ticket-close-time is failing; an AMC measured by preventive-event-cadence is working.
Read in methodology →lifecycle
Lifecycle economics over capex minima
The cheapest specification at year one is rarely the cheapest at year seven. Specify against total lifecycle cost.
Read in methodology →lifecycle
Technology refresh on a published cadence
Every system has an end-of-life. Plan the refresh; don't be surprised by it.
