Did you know that the loading dock typically drives the design of the building? True, especially with performing arts buildings. Moving audience members through level changes in the lobby and auditorium is often easier than moving scenery and other heavy equipment between the loading dock and the stage. Here are some recommendations to consider when designing your next loading dock.
The first decision is how many vehicles need to be accommodated for the venue. A single truck? Three to six trucks for a Broadway-style touring house? Space for catering deliveries, tour buses, a broadcast vehicle, and a dumpster? It is important to get this right. A venue with frequent catering service may require a separate loading dock as simultaneous food service and show loading can create conflicts.
Depending on the weather and climate, the type of venue, the capability of the crew, and the frequency of loading and unloading, the loading dock can be flush to the loading doors, have a covered exterior loading platform, or be entirely enclosed. To facilitate personnel access to the dock level, a stair should be provided. For facilities that may have frequent deliveries by small trucks or vans, a 1:12 ramp to accommodate carts and dollies may be needed.
Various industry resources recommend loading dock heights ranging from 44” to 55” above wheel level. Long-standing OSHA guidelines indicate a dock height of 44” to 48”. For docks with multiple bays, at least one bay should be equipped with an industrial quality dock leveler. Recommendations for the allowable maximum slope for the truck box vary from 2% to 10%. The more level the truck box the better, with the accommodation of a slight angle to facilitate drainage away from the building. Where a loading space is angled toward the building, a heavy duty drain slot and cover should be provided, with the drain not under the typical wheel location. Note that if the truck box is sloped toward the dock platform and exposed to rain, water may drip off the back of the truck roof and onto the crew.Additional considerations include industrial quality adjustable lighting for each vehicle, edge guards and bumpers, a hose bib, shore electrical power, cable pass-throughs for connections to and from the interior of the building, non-slip floor surfaces, and exhaust removal for enclosed docks. Overhead coiling doors are typical for loading docks. Trailer restraints may be required if forklifts are expected. A well-lighted personnel door is also essential.
What the loading dock is NOT: the stage door for staff and performers, the backstage smoking zone, and the emergency egress path from the backstage area.
The design of the loading dock is critical for performance venues of all sizes. A well-designed loading dock can enhance crew safety, reduce labor time and cost, and, in the case of touring venues, contribute to the industry reputation of the facility. It is important to get this right.
