Use an agreed design as the comparison unit
The cost of an event structure depends on the complete arrangement and the work required to deliver it. Start by agreeing the equipment it supports, placement, appearance, venue, installation window and dismantling conditions. Then ask suppliers to quote that same scope. Metres of truss or the number of towers are useful inventory details, but do not establish an equivalent outcome.
A lower equipment subtotal may be offset by services elsewhere in the budget. Conversely, a more complete proposal may already include work that another quotation leaves to the organiser. Request a clear boundary between the contractor's scope, venue services and client contributions.
Read the budget in layers
| Cost area | What may be included | Question for the quotation |
|---|---|---|
| Structural equipment | Specified components, bases, connections and required accessories | Is this the complete proposed assembly? |
| Design and preparation | Drawings, technical review, coordination and preparation of the equipment | Which deliverables and revisions are included? |
| Venue services | Approved suspension provision, venue labour or other required services | Who orders them, and where is their cost recorded? |
| Installation and dismantling | Crews, supervision, handling and the agreed sequence | Are both ends of the event and the actual access windows covered? |
| Access and logistics | Transport, loading arrangements, handling equipment and storage | Which venue restrictions and deliveries were assumed? |
| Event operation and changes | Any agreed attendance, inspections or additional changes | What is included, and what requires a revised quotation? |
Do not assume every project needs every line. A simple floor installation and a complex flown arrangement have different scopes. The purpose of the table is to reveal responsibility and omissions, not to add unnecessary services.
Venue costs deserve their own check
The venue may define who can provide particular services and how they must be ordered. Messe Frankfurt, for example, describes individually assessed suspension enquiries followed by customised offers. That supports a practical budgeting step: obtain the actual venue's response rather than borrowing a rigging allowance from a previous event.
Ask whether the quoted contractor total includes those external services, carries an estimate for them or excludes them entirely. Keep any pending venue amount marked as pending. Treating an unconfirmed cost as zero makes an early budget appear more complete than it is.
Hypothetical example: two proposals for one presentation area
Imagine a brief for a display with a branded overhead element and lighting, with the same agreed geometry in both proposals. Proposal A lists structural components and delivery. Proposal B lists those components, installation, dismantling and preparation of the venue submission. Neither document yet contains the venue's final service offer.
It would be misleading to compare the two totals immediately. Ask A to add the missing work or show which separate contractor will provide it. Ask B to confirm the boundaries of its venue coordination. Add the same confirmed venue scope to the comparison, once available, without counting it twice.
The resulting comparison should contain a common base scope, clearly identified optional items and unresolved amounts. If one supplier proposes a different support method, evaluate that as a design alternative with its own footprint and appearance. It is not a like-for-like discount simply because the screen remains the same size.
Which changes usually require a new scope discussion?
Changing attachment positions, adding scenery, moving to another hall or compressing the build window can affect the work needed. A request to conceal the structure may introduce finishing, access and coordination requirements. A late return time can alter dismantling and transport arrangements. Ask the supplier to describe the consequence rather than assume a universal surcharge.
For cost reduction, identify flexible outcomes: visible finish, installation concept, decorative extent or the timing of work. Ask which adjustment simplifies delivery while preserving the important audience experience. Removing an unidentified accessory from the list is not a useful budgeting method; the technical team must retain the components required by the approved arrangement.
Before accepting the comparison
Attach the same design revision, equipment scope and venue information to both requests.
Confirm equipment supply, installation, dismantling, transport and storage responsibilities.
Separate confirmed external costs from allowances and exclusions.
State the currency, tax treatment and dates covered so the totals can be read consistently.
Record the process for approving a changed design or additional work.
Bring your layout, venue response and schedule to installation and dismantling planning. If the arrangement itself is still open, start with design and visualisation and structure options, so the quotation describes an agreed result.
