Pre‑installation planning: surveys, design and approvals (1–6 weeks)
Procurement and lead times: realistic expectations (1–8+ weeks)
Onsite installation phases and realistic durations
- Pre‑installation mobilisation (1–2 days): site set up, access control, temporary protection of finishes. Coordinate with site manager.
- Rigging and structural fixings (1–3 days): mounting screens, speaker brackets, lighting bars. Structural surveys beforehand avoid surprises.
- Cabling (2–5 days): power, AV and network cabling, rack cabling and labelling. Good installers pre‑dress and test cables as they run them; expect this to be labour‑intensive.
- Rack build and equipment fit (1–3 days): install amplifiers, processors, matrix switchers and control hardware in the AV rack.
- Commissioning and tuning (1–4 days): audio system tuning (measurement, EQ and zoning), screen calibration, control system programming and matrix routing verification. Audio tuning alone can take a full day for each major zone depending on complexity.
- Final testing and customer walkthrough (0.5–1 day): fault checks, operator training and handover documentation.
For larger or phased projects these activities may be spread over several site visits and coordinated around venue closures or quieter trading periods.
Integration, testing and acceptance — what must be signed off?
Common factors that extend duration — risks and mitigations
- Site access & opening hours: If installers can only work outside trading hours, the installation will take longer. Plan phased work during closures where possible.
- Structural surprises: Unforeseen fixings, hidden beams or services can delay rigging. Mitigation: a pre‑install structural review and contingency days in the programme.
- Power upgrades: AV and lighting can require additional MCBs or dedicated circuits. Early electrical surveys save time; allow for electrician lead times.
- Long lead equipment: Order core long‑lead items early and accept approved alternates where appropriate.
- Control integrations: Third‑party systems (booking, building management, fire panels) can require coordination with other contractors; arrange integration meetings early.
- Last‑minute scope changes: Change orders disrupt schedules and require revised programmes. Lock scope before procurement where possible.
