Large Artificial Trees Site Access Requirements David Hurtado Sep 29, 2026 Table of Contents A specification package for a hotel lobby called for a fourteen-foot canopy tree as the anchor piece of the reception area. The tree was fabricated, crated, and scheduled for delivery before anyone on the project team walked the actual path it would need to travel: through a service corridor, into a freight elevator sized for a different kind of load, and around two ninety-degree turns before reaching the lobby floor. That gap between what gets specified on paper and what a building can physically accommodate is one of the most common causes of delay on large tree installations. The problem shows up most often with large feature tree installations, where a single canopy or trunk section is simply too tall, too wide, or too heavy to pass through a standard doorway, a passenger elevator cab, or a tight stairwell turn. None of that has anything to do with which carrier is booked or how the crate is built. It comes down to whether the finished piece, in one section or several, can physically move from the delivery truck to the exact spot where it will stand. We treat site access as its own planning step, separate from structural specification and separate from how the shipment itself is arranged, because it depends entirely on details that only exist at the building: door leaf widths, elevator cab depth, dock height, and whether building management will grant after-hours access for an oversized delivery. Catching a clearance problem during design costs nothing. Catching it on delivery day costs a rescheduled crew, a blocked lobby, and sometimes a tree that has to go back on the truck. Conducting a Site Survey Before Delivery Before a tree design is finalized, the access route deserves the same scrutiny as the space where the tree will stand. A site survey answers one question: can this piece, at its final dimensions, get from the loading area to the installation point without being taken apart? Skipping that step and relying on architectural drawings alone is where most access problems start, because as-built conditions rarely match the plans exactly. Door hardware gets swapped, corridors pick up additional signage or fire equipment, and elevator cabs get resurfaced with padding that eats into usable width. What to Measure and Document A useful survey records more than a single number for each opening. It captures clear width and height at every doorway along the path, the interior dimensions of any elevator cab that will be used, corridor width at its narrowest point rather than at the entrance alone, and the height of any low soffit, sprinkler head, or light fixture that hangs into the route. Photographs of each point, taken with a tape measure or a laser measure visible in frame, remove any ambiguity later about what was actually checked. Who Should Be Involved The survey works best as a joint effort. Someone from the install team who has seen the tree’s actual finished dimensions, not just the specification sheet, needs to walk the route, because a canopy’s widest point is not always obvious from a drawing. A building contact, whether that is property management, a facilities engineer, or building security, needs to confirm elevator capacity, dock hours, and any access rules a visiting install crew would not otherwise know about. Doorway, Hallway, and Corridor Clearances Doorways and corridors are usually the first constraint and the easiest one to underestimate, because a door’s nominal size on a floor plan is rarely its true clear opening. Clear Width, Height, and Turning Radius A commercial door’s clear width is measured with the door open to ninety degrees, not the width of the frame, and it is almost always narrower than the frame dimension once the door leaf and any closer hardware are accounted for. Ceiling height matters just as much along hallways as it does at any single doorway, since a tree’s canopy may need to travel horizontally, tilted, or upright depending on the route. Corners are where clearance calculations go wrong most often: the diagonal distance a rigid object needs to clear a ninety-degree turn is shorter than the corridor’s straight-line width, which means a piece that fits through a hallway in isolation can still get stuck at the turn into it. Fixed Obstructions Along the Route Nominal dimensions do not account for what is actually mounted in the space. Door closers, kick plates, transition strips, low soffits, sprinkler heads, wall-mounted fire extinguisher cabinets, and hanging light fixtures all reduce usable clearance below what a floor plan shows. A route that looks clear on paper can be blocked by a single sprinkler head positioned a few inches lower than expected, which is exactly the kind of detail a physical survey catches and a drawing review misses. Elevator and Freight Elevator Access Passenger Elevator Limitations Passenger elevators are rarely a realistic option for a full-height tree. Cab interiors are often shallower than their door width suggests, weight capacity is calculated for occupant loads rather than a single concentrated object, and building policy in many commercial properties simply prohibits using passenger cabs for oversized freight during business hours. Confirming this early prevents a crew from arriving with a piece that was never going to fit the only elevator they were told to use. Freight Elevator Cab Dimensions and Door Height Freight elevators solve most of the passenger-cab problem, but their dimensions still vary widely by building age and design. A taller door does not guarantee a deeper cab, and a freight elevator’s rated load capacity needs to be checked against the tree’s actual weight, including any base, planter, or packaging still attached during transit. The only reliable way to confirm any of this is a measurement taken inside the actual cab, not a number pulled from a building’s general specifications sheet, which may describe the elevator as it was installed rather than as it exists today. Loading Dock Access and Staging Dock Height and Approach Dock height needs to match the delivery vehicle, not the other way around. A dock built for a standard box truck may sit at the wrong height for a smaller delivery vehicle, requiring a lift gate or ramp that adds time and changes how the piece needs to be handled during unloading. Truck approach and turning radius matter just as much as the dock itself on dense urban sites, where a delivery vehicle may not be able to back straight into the dock and instead needs to unload curbside. Staging and Temporary Storage Space A tree rarely moves directly from the truck to its final position in one continuous motion. It needs a staging area near the entry point where crating can be removed and the piece can be inspected before it travels further into the building. Potted and planter-based trees add another variable at this stage: the combined weight of a rooted trunk system and a filled planter base can exceed what a single dolly or two people can safely maneuver, which changes how much staging space and how many hands the move actually requires. A hallway is rarely a workable staging area on its own, since blocking it for an extended uncrating process interferes with everything else happening in the building that day. Coordinating with Building Management and Security Building Rules for Oversized or High-Value Deliveries Most multi-tenant commercial buildings have their own rules for anything larger than a standard package delivery, and those rules typically have nothing to do with the tree itself. A certificate of insurance naming the property, a reserved block of freight elevator time, protective coverings for finished floors and walls in common areas, and a security escort for a high-value piece are common requirements that need to be arranged well before delivery day, not discovered on it. Many property management teams also set their own clear-passage minimums for anything moved through shared corridors, often benchmarked against the door and corridor width figures published in the 2010 ADA Standards for Accessible Design, even where the delivery itself has nothing to do with accessibility compliance. Confirming a building’s specific requirements early avoids a delivery crew being turned away at the dock because paperwork was never filed. When Disassembly for Transit Is Necessary Assessing Whether a Tree Needs to Travel in Sections When a site survey turns up a doorway, stairwell, or elevator that the tree’s assembled dimensions simply will not clear, the practical answer is moving it through in sections rather than redesigning the building’s access points. The critical measurement is the tightest point on the route, not the average one: a tree that fits everywhere else on the path still needs to travel disassembled if a single stairwell landing is too narrow. For projects where that constraint is identified early, we build around a fully custom sectional design engineered to separate at defined points and go back together on-site without visible seams. Reassembly at the Final Location Reassembly space is itself a site-access consideration, separate from the clearance question that made sectioning necessary in the first place. The final installation point needs enough open floor area and ceiling height to bring sections together, secure internal connections, and shape the canopy once it is standing. That work is far harder to do well in a cramped corner than in the open staging area identified during the original survey. Flagging this need during the site survey, rather than discovering it once the sections are already inside the building, keeps reassembly from becoming its own access problem.

It has to be checked at the building itself, against the tree’s real dimensions, early enough that a tight doorway or an undersized freight elevator changes the plan rather than derailing delivery day. A survey that documents clear width, corridor turns, elevator cab dimensions, dock height, and staging space, paired with early coordination with building management, turns what could be a delivery-day surprise into a routine step in the installation process. When a route genuinely cannot accommodate a piece in one section, planning for disassembly from the start keeps that constraint from becoming a last-minute problem. FAQ How much clearance does a standard doorway need for a large artificial tree? A commercial door’s true clear opening is smaller than its frame width once the door leaf and any closer hardware are accounted for, so the tree’s assembled width and height both need to be measured against the actual open-door clearance, not the nominal door size listed on a floor plan. What happens if a building has no freight elevator? Some buildings only have passenger elevators, which are rarely sized or rated for a full-height tree. In that situation, the piece typically needs to travel through in sections small enough for the passenger cab, or the installation route needs to shift to a stairwell or an alternate entrance identified during the site survey. Who is responsible for measuring the access route before delivery? It works best as a shared responsibility. The install team needs to confirm the tree’s actual finished dimensions against the route, and a building contact, such as property management, facilities staff, or security, needs to confirm elevator capacity, dock hours, and any access rules specific to that property. Can a large artificial tree be disassembled and reassembled without damage? Yes, when the piece is engineered for it from the start. Trees intended for tight-access sites are typically designed with defined separation points so sections can be moved independently and rejoined cleanly, rather than being taken apart in a way that was never planned for. How far in advance should a site survey happen? Ideally before the tree’s final dimensions are locked in, so a tight doorway or elevator can influence the design rather than force a last-minute change. At minimum, it should happen with enough lead time to arrange building access, staging space, and disassembly if the route requires it.
