EVENT PLANNING GUIDE
Why Bump-In Is Always Slower Than You Think
Updated on July 25, 2026 | Written by Rachella Thomas
No matter how experienced the event planner is or how detailed the run sheet, bump-in and set-up will almost always take longer than expected.
Bump-in is one of the least predictable parts of the entire event lifecycle.
The Ideal vs. The Reality
On paper, bump-in looks smooth.
You’ve got a great run sheet. You’ve listed every delivery, every task, every contractor arrival. You’ve stacked it all back-to-back with military precision. You’re feeling proud of your beautifully formatted run sheet.
And then reality hits.
It’s event day, and the AV supplier is late because the truck is stuck in traffic. Also, the venue doors aren’t unlocked. Or there’s a power issue. Someone packed the wrong cables. And now you’re 90 minutes behind before you’ve even started.
It’s not poor planning. It’s just how events work.
Unlike a week-long studio shoot or office-based project, you’re relying on dozens of external variables within a limited timeframe: access points, permits, forklifts, wind, Wi-Fi, weather and contractors you don’t employ.
Even the best-looking event run sheets can get tangled in bump-in unpredictability.

Why Event Day Schedules Often Fail
Let’s look at what got us here so you can start planning to avoid the pitfalls.
Here are some common reasons bump-in timelines fall short:
Optimism Bias: Inexperienced event planners often plan for the best-case scenario, which is ideal, not necessarily real. That’s not strategy; it’s hope.
Lack of Buffer Zone: When one task runs late, it delays everything else. This happens when you squeeze deliveries and event setup tasks back-to-back with no wiggle room.
Underestimating Changeover Times: When it comes to the day's schedule, event planners often forget the realities of changeover. Resetting a space between setups takes time.
Too Many Moving Parts: Large events often have 15+ suppliers and vendors. Each has its own timing and pressure points, which can easily throw off your overall event schedule. Review each supplier's schedule to make sure it makes sense and includes a buffer zone for a time blow-out.
Most event-day timelines fail because they assume everyone will show up as planned, have what they need, and finish on time. Unfortunately, experience shows us that’s rarely the case.
What Can You Do About It?
You’ve got two opportunities to prevent bump-in blowouts. The first is in your pre-event planning, and the second is troubleshooting at the event. If you put both into practice, you’ll be ahead of most event planners!
1. Add Buffer Time Between Critical Tasks
Instead of jamming tasks together, build in space between deliveries, setups, and rehearsals. Think 15–30 minute blocks, not 5-minute handovers.
2. Stagger Arrivals Logically
Not everyone needs to arrive at 8 am. Schedule key trades in waves, based on what’s actually achievable. This avoids congestion and improves focus.
3. Over-Communicate Bump-In Details
The more information your vendors have, the less they’ll need to ask on site. Provide maps, dock information, vehicle clearance heights, parking instructions and a detailed contact list.
4. Have a Triage Mentality
Don’t try to fix everything at once. Prioritise what you need to keep progress moving. One delayed supplier shouldn’t stall the entire site.
5. Plan for Contingency
What’s your backup if power isn’t live? If the furniture is late? If it rains? Build these conversations into your planning, so you’re not starting from zero when something goes wrong.
Bump-in isn’t just logistics. It’s a human one. People get tired, and they forget things. They need clear instructions. They lose tools. They need to eat. The best bump-ins have a leader who understands flow. Someone who can call the shots, shift priorities and read the room. That leadership matters as much as the plan.
What Next?
I recommend taking a few minutes to read through your run sheet and review the timing and flow. Respect the unknowns, and accept that your event day will be unpredictable.
Trust that a slightly slower plan will get you to showtime in much better shape.
