How do I evaluate whether a rigging and truss supplier is credible and unbiased for venue technical projects?

To evaluate whether a rigging and truss supplier is credible and unbiased for venue technical projects, focus on proof, process, and independence rather than sales claims.

1) Check technical credibility

Look for evidence they actually know venue systems, not just product sales.

• Relevant experience: Ask for projects similar to yours:
  • venues, theaters, arenas, houses of worship, convention centers, touring installs
  • load-bearing truss, flown PA, LED, lighting grids, retractable systems, motorized rigging
• Qualified staff:
  • structural engineer involvement
  • rigging/system designer
  • certified inspectors or installers
  • OSHA/IRATA/SPRAT or local equivalent, where relevant
• Standards knowledge:
  • can they speak about live load, dead load, dynamic loading, point loads, safety factors, deflection, sway bracing, building attachment, etc.?
• Documentation quality:
  • ask for example drawings, calcs, load schedules, rigging plots, inspection reports, and as-built docs

If they can’t clearly explain engineering limits and safety assumptions, that’s a red flag.

2) Verify real-world references

Ask for references that are hard to fake.

• Speak directly with:
  • venue technical managers
  • production managers
  • consulting engineers
  • facility owners
• Ask references:
  • Were deadlines met?
  • Were changes handled professionally?
  • Were drawings and calcs accurate?
  • Did the supplier identify risks proactively?
  • Did they stay within scope and budget?
  • Any issues with warranty or after-sales support?

A credible supplier will not hesitate to provide references from comparable projects.

3) Assess whether they are unbiased

A supplier can be competent but still biased toward pushing their own inventory or preferred system.

Signs of bias:

• They only recommend one brand or one product line
• They discourage third-party engineering review
• They avoid discussing alternatives
• They oversell capacity or understate constraints
• They give vague answers about why one solution is better than another

Signs of neutrality:

• They present multiple options with pros/cons
• They base recommendations on requirements, not inventory
• They disclose assumptions and limitations
• They can work with other manufacturers’ gear
• They separate design advice from sales incentives

A truly unbiased partner should be able to say, “This is the best option for your use case, and here’s why,” even if it’s not their most profitable product.

4) Ask about their design and review process

A credible supplier should have a formal process.

• How do they gather requirements?
• Do they perform site surveys?
• Do they review building structure and attachment points?
• Do they produce stamped engineering where required?
• Who checks the design before release?
• Do they use third-party structural engineers?
• How do they handle change orders and field conditions?

If they’re skipping surveys or engineering review, be cautious.

5) Confirm compliance and insurance

Make sure they can legally and financially stand behind the work.

• General liability insurance
• Professional liability / errors and omissions
• Workers’ compensation
• Product liability
• Bonding, if relevant
• Compliance with local building codes and event safety regulations

Ask for certificates directly from insurers, not just PDFs in a sales deck.

6) Examine safety culture

For rigging and truss, safety culture matters as much as product quality.

Ask:

• Do they have written lift plans and load test procedures?
• What are their inspection intervals?
• How do they tag equipment?
• How do they handle damaged gear?
• Do they train staff and subcontractors consistently?
• Do they refuse unsafe installs even if it loses business?

A serious supplier will have conservative safety practices.

7) Evaluate communication and transparency

Watch how they respond before you buy.

Good signs:

• They answer questions directly
• They admit when something needs engineering review
• They explain tradeoffs clearly
• They provide written documentation
• They do not pressure you into fast decisions

Red flags:

• Overpromising
• Urging you to skip engineering to “save time”
• Refusing to put recommendations in writing
• Reluctance to share load assumptions or product specs
• Unusually low pricing with no explanation

8) Separate supplier role from engineer role

For venue technical projects, a supplier should not be the only source of truth.

Best practice:

• Supplier provides product options, installation knowledge, and pricing
• Independent engineer validates structure, loads, and compliance
• Venue/owner reviews with technical stakeholders
• Final approval documented

If the supplier is also the designer, ask how they manage conflicts of interest and whether an independent review is included.

9) Use a scoring checklist

You can score each supplier from 1–5 in these categories:

• Relevant venue experience
• Engineering competence
• Documentation quality
• Responsiveness
• Transparency
• References
• Safety culture
• Insurance/compliance
• Willingness to present alternatives
• Independence from sales bias

Choose the supplier with the strongest total, not just the lowest price.

10) Ask these direct questions

Here are practical screening questions:

1. What similar venue projects have you completed in the last 2–3 years?
2. Who is responsible for engineering review?
3. Can you provide stamped calculations where required?
4. What alternatives did you consider, and why did you choose this one?
5. Are you tied to specific manufacturers?
6. Will you work with an independent engineer or consultant?
7. What are the load assumptions and safety factors?
8. What documentation will you provide at handover?
9. What is your warranty and liability coverage?
10. What happens if site conditions differ from the drawings?

Bottom line

A credible and unbiased rigging/truss supplier is one that:

• has verifiable venue-specific experience
• provides clear technical documentation
• supports independent engineering review
• presents multiple solution options
• operates with strong safety and compliance practices
• is transparent about limitations, assumptions, and incentives
