The AV derig process is the planned dismantle, safe lowering and removal, packing, and signed handover of all flown and floor AV elements once an event closes. Before your crew touches a single cable, three things must be confirmed: valid LOLER certificates for all lifting equipment are on site, a written RAMS (Risk Assessment and Method Statement) covering derig activities is available, and the venue rigging supervisor’s sign-off process is agreed.
Immediate priorities at a glance:
Who must be present for sign-off: head rigger, venue rigging supervisor, and stage manager. The single most urgent action before lowering any flown element is confirming lift permits and MEWP operator competence are in order.
A crew brief lives or dies by clarity. Print this, paste it into your production pack, and tick each item as it clears.
Operational checklist (in sequence):
Roles, responsibilities and sign-off checkpoints:
| Role | Core derig responsibility | Sign-off checkpoint |
|---|---|---|
| Head rigger | Supervises all lowering operations; confirms LOLER docs | Pre-derig inspection log; final rig completion sign-off |
| Riggers | Execute lowering, dismantle and pack of flown elements | Mid-derig checkpoint after each flown zone clears |
| Stage manager | Coordinates overall sequence and crew timing | Show-end call-down; final venue handover |
| Audio lead | Manages speaker and console dismantle and pack | Audio equipment inventory sign-off |
| Lighting lead | Oversees fixture lowering, cable coiling and pack | Lighting inventory and flightcase seal |
| Video lead | Protects LED panels and encoders until streaming checks complete | Video equipment sign-off post-stream confirmation |
| MEWP operator | Operates platform for access at height; holds valid IPAF card | Pre-use MEWP inspection log |
| Venue rigging supervisor | Reviews loads against structural data; approves secondary suspensions | Formal rig sign-off at trim height and on completion |
Documentation to carry on site:
Event AV operator role descriptions consistently list setup and dismantle coordination as core duties, and senior AV technician job briefs make rigging and derig planning an explicit responsibility at that level.

Start with a site walk-through at least a week before the event. Walk the load-out route, note access restrictions, confirm vehicle marshalling positions, and mirror the load-in architecture in reverse. Agree the derig access window with the venue in writing. Waste strategy (cable ties, foam offcuts, pallet wrap) and security handover timing both need to be locked before show day.

Professional AV production treats site liaison and documented RAMS as core project management, not optional extras. That framing matters: a derig plan written without a venue walk-through is guesswork.
Call a timing countdown 30 minutes before the show closes. Confirm the power-down order with the audio, lighting, and video leads. The sequence runs: streaming encoders and broadcast interfaces stay live until post-event checks are complete; floor equipment powers down next; flown elements are isolated last. Tag every suspended item before any load is transferred to a hoist.
Pro Tip: Never lower a flown video wall until the video lead has confirmed the stream has ended and all recording devices have stopped. Cutting power mid-frame on an LED panel can damage driver cards that cost more to replace than the labour saving is worth.
Sequence flown equipment before floor equipment wherever access allows. Use secondary suspensions as a safety net during lowering, not as a primary load path. MEWP operators should position the platform to give riggers a clear working zone, with tag lines attached to loads before the hoist releases tension. LED screen handling during derig requires panels to be lowered flat, never tilted, and stacked in the original flightcase foam.

Pack in reverse build order so the first item into the truck is the last item needed at the next venue. Label every flightcase with contents, destination, and fragile warnings before it leaves the stage.
Complete the post-rig inspection log before any vehicle departs. The head rigger and venue rigging supervisor both sign the completion checklist. The stage manager countersigns the venue handover document. Any damage discovered during dismantle goes into an incident report immediately, not retrospectively. Replenish consumables (cable ties, tape, foam) from the vehicle spares kit so the next build starts complete.
UK event derig sits under several overlapping legal and industry frameworks. Getting the paperwork wrong is not a minor admin issue; it is a liability.
Statutory and industry documentation required on site:
Crew competence checks on arrival:
Inspection and sign-off process:
The venue rigging supervisor’s role is to review suspended loads against structural calculations and sign off the rig only once trim height and secondary suspension details are confirmed. Their sign-off is not a formality — it is the venue’s formal confirmation that the structure is safe to load and, later, safe to strike. Involve them at the walk-through stage, not at the point of lowering.
The venue rigging supervisor is the technical gatekeeper for everything suspended in the building. Early collaboration prevents late changes to secondary suspensions and secures a clean sign-off. At the site walk-through, exchange trim heights, secondary suspension requirements, roof access procedures, and any access restrictions that affect the derig sequence.
Stakeholder coordination checklist:
For events with live captioning or accessibility technology that must remain active until all delegates have left, coordinate with the relevant supplier before the power-down sequence begins. Live captioning systems in particular need a confirmed end-of-session signal before their equipment can be struck.
Pro Tip: Build the venue rigging supervisor sign-off into the crew schedule as a named task with a time slot, not a vague “when ready.” If sign-off is on the critical path, it gets done on time. If it is an afterthought, it becomes the reason the truck sits waiting for 45 minutes.
Most derig problems are predictable. The ones that cost money are almost always the ones that were not planned for.
Common failure modes:
Preventive measures:
On-site risk mitigation:
Derig time varies significantly by event type. The UK events sector spans conferences, exhibitions, cultural events, and outdoor productions, each with different access constraints and kit complexity.
Typical timeline examples:
Derig time varies by event type, ranging from brief packdowns for small corporate AV setups to extended operations for large theatre or concert loadouts requiring significant crew numbers.
Resourcing rules of thumb:
For multi-venue AV logistics, overnight storage between legs needs a confirmed depot location and a vehicle manifest that matches the post-derig inventory exactly.
Every derig requires rated lifting equipment and appropriate personal protective equipment. The essentials:
Pro Tip: Colour-code your cable ties by department: one colour for audio, one for video, one for lighting. It takes 30 seconds at pack-down and saves 20 minutes at the next build when the video lead is not untangling audio snake from lighting cable.
For a fuller breakdown of AV equipment types and handling requirements, the equipment category matters as much as the quantity when planning packing time.
Fireflyav uses a structured checklist approach on every production, designed to be printed and attached to the crew pack. The format below reflects the process the team follows on site.
Fireflyav operational derig checklist:
QA and sign-off template:
| Stage | Check | Signed by |
|---|---|---|
| Pre-derig | LOLER docs, RAMS, IPAF cards, secondary suspensions | Head rigger |
| Mid-derig | Flown zone cleared, panels in cases, no loose loads | Head rigger and venue rigging supervisor |
| Final sign-off | All equipment packed, venue restored, incident log complete | Stage manager, venue rigging supervisor, transport lead |
Pro Tip: For hybrid events where a stream is still running post-show, assign a dedicated crew member to the streaming station with a clear instruction: nothing in that zone moves until the video lead gives a verbal “stream confirmed closed.” A Blackmagic Web Presenter or similar interface left live during derig is a common source of post-event client complaints and, occasionally, a broadcast incident.
Fireflyav’s technical support services cover site walk-throughs, RAMS preparation, and certified crew supply for productions across the UK.
A safe, dispute-free AV derig in the UK depends on three things being in place before the show ends: the right documentation, the right crew competence, and a signed handover process that is built into the schedule, not bolted on at the end.
| Point | Details |
|---|---|
| Verify LOLER and RAMS first | Confirm lifting equipment certificates and a derig-specific RAMS are on site before any lowering begins. |
| Lock in the venue sign-off process | Agree the venue rigging supervisor’s sign-off checkpoint at the walk-through, not on derig day. |
| Plan vehicle marshalling in advance | Confirm arrival slots with the transport contractor 48 hours before derig to avoid loading bay delays. |
| Resource to flown-element complexity | Allow one rigger per two flown points minimum; scale floor crew to match the kit volume, not the room size. |
| Fireflyav for certified derig support | Fireflyav supplies certified crew, RAMS preparation, and site walk-throughs for UK event productions. |
The conventional wisdom in event production is that derig is just the build in reverse. It is not, and treating it that way is where most problems start.
A build happens with time to correct mistakes. Derig happens under pressure: the venue wants the space back, the transport contractor is waiting, and the crew has already worked a full show day. That pressure is where documentation shortcuts happen, where a sling with a borderline inspection date gets used anyway, and where the venue rigging supervisor sign-off gets skipped because “we’ve worked here before.”
The fix is not more paperwork. It is embedding the critical checkpoints into the crew schedule as named tasks with owners and times. When the head rigger knows they are signing the pre-derig inspection log at 22:30 and the venue supervisor knows they are doing a mid-derig checkpoint at 23:15, those things happen. When they are listed as “to do when ready,” they get compressed or skipped.
There is also a tendency to treat the post-derig QA log as an admin task for the office. It is not. A signed pre- and post-derig checklist kept in the vehicle manifest reduces disputes over missing items and creates an auditable record for insurance purposes. That record has real value the first time a client queries a damaged panel or a venue charges for something left behind.
The best derig crews are not the fastest. They are the ones who finish with every item accounted for, every certificate in the file, and a venue that will have them back.
When the show ends, the work that protects your kit, your client relationship, and your compliance record begins. Fireflyav provides the full technical picture for UK event productions: site walk-throughs before the build, RAMS preparation that covers derig explicitly, certified riggers and MEWP operators, and transport coordination for load-out.

For planners who need a derig crew that arrives with the right documentation, the right qualifications, and a signed handover process already built into the schedule, Fireflyav’s technical services cover corporate conferences, cultural events, broadcast productions, and live events across the UK. The team handles the compliance detail so you can focus on the client.
