The costly decision is usually made before anyone chooses a car finish or door type. When considering how to specify commercial lifts, start with the person who will operate the equipment, the load they will move and whether that person needs to travel with it. Those answers determine the type of equipment, the building interface and, in tenant-facing buildings, the ongoing staffing model.
A lift contractor should be able to turn that operating brief into a recommendation. A list of technical questions is not a specification strategy when the owner is still deciding how the building will run.
Start with the operating model
A multi-level self-storage facility, warehouse and hospitality back-of-house area may all move bulky goods between levels. Their lift requirements can still be very different.
In self-storage, the question is often whether customers can move their own goods between floors. If a tenant is expected to travel with their trolley, cage or other load, the equipment needs to be designed and certified for people to travel. That changes the lift selection, controls, door arrangement and the way it is used day to day.
A permanent goods hoist can be a sensible choice where a trained attendant controls the operation and no person travels with the load. It can reduce the initial equipment scope. The other side of that saving is operational: someone has to be available whenever goods need moving. For a facility with regular customer access or a lean on-site team, that roster requirement can become the more significant cost line.
In a warehouse, the answer depends on who uses the lift and how predictable the work is. A controlled goods movement between two work areas may suit attendant-operated equipment. A building where several staff need to move stock independently will usually need a different operating arrangement. Do not specify around the heaviest occasional item alone. Look at the normal load, the largest credible load, frequency of use, trolleys or pallet handling, and whether users have clear sight and control of the load.
Construction hoists belong in this comparison too, but only for the work they are designed to do. They are temporary construction equipment, useful while a building is being built. They are not a substitute for a permanent lift once the building is handed over. Treating one as a shortcut can defer decisions about the shaft, landing entrances, controls and final operating model until they are harder to change.
How to specify commercial lifts around the user
Write the operational brief in plain terms before finalising the lift schedule. It should state who calls the lift, who loads it, who travels in it, what occurs at each landing and who is responsible when something stops mid-process.
This matters particularly where the building will be run by tenants, customers or mixed staff groups. Equipment intended for a trained operator is not automatically the right answer for a public-facing workflow. Conversely, a people-carrying goods lift may add scope that a tightly controlled industrial process does not need. The right choice follows the user, not the label on the drawings.
Capacity and car size should follow the actual handling method. A lift that accepts the stated mass but cannot accommodate a trolley turning, a roll cage or the longest stock item will force a workaround from the first day. Door width, car depth, clear landing space and approach direction are part of the same decision. A pallet may fit through an opening yet still be impractical to position without repeated manoeuvring.
Also consider peaks. A self-storage facility can have concentrated weekend use. A warehouse may have short, intense dispatch periods. A retail back-of-house lift may be quiet for most of the day then carry delivery loads in a narrow receiving window. These patterns affect traffic, door cycles and the practical tolerance for waiting or downtime.
Set the shaft out as a lift component
A shaft is not simply an empty rectangle left for the lift contractor. Its structure, openings and alignment directly affect installation and long-term operation.
The guide rails have to remain parallel over the full travel. If the shaft moves, narrows, twists or steps between levels, the installation team has to resolve that at the interface. Sometimes it can be managed with additional work. Sometimes it changes the available equipment arrangement. Neither outcome is helped by discovering the condition after linings, fire services and finishes are in place.
Confirm early how the shaft will be built and checked. This includes the wall construction, structural fixing zones, slab edges, landing openings, lintels or framing above doors, pit construction and overhead space. In a steel-framed building, coordinate the lift support requirements with the steel detail rather than assuming lightweight infill can carry them. In masonry or concrete work, confirm set-out before pours and before openings are closed in.
Landing thresholds need the same attention. Finished floor levels, screeds, drainage falls and floor finishes all meet at the entrance. A threshold that is set without reference to the final floor build-up can leave an avoidable level difference or require rework late in the programme.
Treat retrofit work as an investigation, not an assumption
Retrofitting into an existing commercial building is often the right way to make upper floors usable. It is also less forgiving than starting with a clean shaft on a new build.
The first task is to establish what is actually there. Measure the available footprint, floor-to-floor dimensions, headroom and lowest level. Check structure, services, access for materials and where the controller can sit. Existing drawings are useful, but they should be verified on site. Buildings change over time, and concealed beams, services and prior alterations regularly influence the final arrangement.
A compact solution can be attractive where space is limited. The trade-off may be a smaller car, altered entrance position, additional structural work or more constrained service access. Where the building function requires larger loads or people to travel with goods, forcing a small shaft to suit a preferred layout can be the wrong compromise.
Plan how new work meets old. This is where projects commonly lose time: door openings framed into existing walls, bulkheads above entrances, fire and acoustic treatments, floor finishes, power supply routes and making good around new structure. Assign each interface to a party. A note saying “by others” is not enough unless everyone knows exactly what the work includes.
Coordinate the builder’s work before it becomes a variation
The lift package and the builder’s work need to be read together. Builders need clear requirements for shaft construction, door openings, structural supports, pit and overhead spaces, power provisions, controller location and access arrangements. The lift contractor needs the final architectural and structural information early enough to identify conflicts.
Controller location is often left late because it takes little floor area on a plan. It still needs a practical, secure position with service access and a workable cable route. Locating it behind fixed joinery, in a tenancy with restricted access or where later building works can obstruct it makes routine service more difficult than it needs to be.
Bulkheads deserve a specific check. Their depth, support framing and final ceiling line must allow for the landing entrance arrangement and door equipment. The same applies to wall linings and reveals. A clean architectural detail is achievable, but only if it is coordinated with the selected lift rather than drawn as a generic opening.
For existing buildings, allow for survey, investigation and staged site access. These are not administrative extras. They are the work that establishes whether the proposed lift can be installed without unplanned changes to structure or services.
Specify the handover operation as carefully as the installation
The selected equipment should be manufactured to the relevant lift standards, including EN 81-20:2020, EN 81-50:2020 and the 2014/33/EU Lifts Directive, then installed in line with AS 1735.1.1:2022 and AS 1735.1.2:2020 and WorkSafe registration requirements. Those references matter, but they do not replace an operational brief.
At handover, the facility team needs to understand normal use, access control, loading limits, fault reporting and how service personnel gain access. Consider who holds keys or credentials, whether tenants can reach all floors, and whether loading activity can block an exit or circulation route. These are building-operation decisions that should shape the controls and access arrangement before commissioning.
Service access should also be planned around the building’s real hours. A lift in a self-storage facility or active warehouse cannot always be isolated during the easiest daytime window. The more clearly the operator, contractor and building manager agree on access from the outset, the easier routine maintenance is to organise.
The strongest commercial lift specification is not the longest one. It is the one that records how the building will work, gives the builder clear interfaces and selects equipment suited to the people who will rely on it long after practical completion.
