The 7-stage cycle,
documented end-to-end.

Every engagement runs through the same structured workflow — feasibility, design, procurement, mobilisation, installation, commissioning, handover. Each stage carries its own inputs, outputs and gate.

Engagement master — the 7-stage delivery cycle

The master workflow that takes a brief from feasibility to handover, with a documented gate at every stage.

The 7-stage delivery cycle is the operating shape of the practice. Every engagement enters at stage 1 (feasibility) and exits at stage 7 (handover), with the option of an AMC contract extending the relationship into the operations phase. The stages are sized so each can produce a discrete sign-off artefact; the gate from one stage to the next is the artefact, not the calendar. The discipline is the gate review. A design that is signed off only because the schedule says so is a design that will be re-opened in commissioning. The 7-stage method is the cadence by which we keep design intent, build reality and operational handover aligned.

/ commissioning

Commissioning workflow — sequence and gates

The energisation, test and sign-off sequence we follow at the commissioning gate of the 7-stage delivery cycle.

Commissioning is the controlled energisation of an integrated system. It is not a power-on; it is a sequence of pre-checks, partial energisation, integrated tests and clause-by-clause compliance reviews. The work is gated — each step needs to pass before the next is attempted. The discipline is the commissioning script. A script that the trade lead has signed off in advance is a script the commissioning engineer can defend at the AHJ walk-through. A script written on the day is a script that will overrun.

  1. Stage 1 · commissioning

    Verify cabling, terminations, earthing, panel layout and labelling before any power is applied.

    Inputs
    Installation log · As-built drawings · Cabling test reports

    Inputs
    Pre-energisation checklist · Commissioning script

    Slice-by-slice test records
    Gates
    Each slice signed before the next is energised

/ maintenance

Maintenance workflow — AMC tier cadence

The annual maintenance cadence we run against an AMC contract — scheduled inspections, preventive replacements, firmware reviews and incident response.

Maintenance is the day-two discipline of the practice. An AMC contract is not a phone number; it is a documented cadence of scheduled inspections, preventive replacements and firmware reviews, with a clear incident-response tier behind it. The discipline is the cadence — when did we last test the battery autonomy on the BESS, when did we last sweep the Cat6A channels, when did we last walk the addressable loop. The workflow below is the tier-1 cadence; tiered upgrades shorten the inspection interval and add 24/7 incident response.

  1. Stage 1 · operations

    Scheduled site inspection

    Walk the building against the AMC checklist — visual, electrical and integration spot checks.

    Inputs
    AMC checklist · As-built drawings · Previous inspection record

    Gates
    Incident closure acknowledged by FM team
    Duration

/ phased rollout

Phased rollout — multi-site / multi-phase delivery

The cadence we follow when a single design pack rolls out across multiple sites or phases — pilot, learning, replicate.

A phased rollout is not a duplication exercise; it is a learning exercise. The first site is the pilot — its design pack is treated as a version-1 to be improved before the rollout begins. The second site validates the improvements. From the third site onwards the cadence is replication, with site-specific deviations logged in a deviation register. The deviation register is the artefact that distinguishes a phased rollout from a series of standalone projects. Every deviation is a learning that feeds back into the master design pack.

  1. Stage 1 · planning

    Pilot site (the version-1)

    Treat the first site as a learning project. Allow the design pack to evolve during delivery.

    Duration
    Full 7-stage cycle
  2. Stage 2 · execution

/ lifecycle

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.
