| Clear Opening Width | Measure the unobstructed passage width when the door is fully open, excluding the frame and hardware. | For an accessible route, plan for at least 815 mm (32 in) clear width where applicable. Common commercial openings are approximately 900–1,200 mm wide. | The selected door leaf, sliding travel, seals, and frame must provide the required usable passage after installation. | Check local code |
| Clear Opening Height | Measure from the finished floor to the lowest obstruction in the opening and header zone. | Accessible door openings commonly require at least 2,030 mm (80 in) clear height in many jurisdictions. Allow additional space for the operator and header. | Insufficient headroom can prevent the operator, track, sensors, and door seals from fitting correctly. | Confirm system drawing |
| Wall and Header Strength | Identify the wall construction, header material, stud spacing, lintel condition, and available fixing points. | The supporting structure must be engineered for the complete door assembly, including the frame, operator, panels, impact loads, and repeated operating cycles. | A swing-slide door transfers loads to the header, jambs, and floor. Weak or flexible supports may cause misalignment and seal failure. | Engineer review |
| Wall Thickness and Frame Fit | Measure the finished wall thickness and check whether the wall is straight, plumb, and suitable for the proposed frame. | Record the actual wall thickness in millimetres. Keep the frame within the manufacturer’s stated adjustment range rather than relying on site trimming. | Incorrect frame depth can create gaps, uneven reveals, exposed fasteners, or interference between the swing and slide movements. | Site measurement |
| Floor Level and Flatness | Check the finished floor across the threshold, swing area, and sliding travel path. | A continuous, solid, and level surface is required. As a planning benchmark, identify deviations greater than about 3 mm over 2 m for correction before installation. | Uneven floors can increase the operating force, damage bottom seals, create trip hazards, and prevent the door from latching. | Correct before fit-out |
| Threshold and Accessibility | Confirm the threshold height, edge profile, drainage detail, and transition to adjacent floor finishes. | Use a low-profile, stable transition where accessibility is required. Avoid abrupt level changes and uncontrolled raised thresholds. | The threshold affects wheelchair access, trolley movement, cleaning, water control, and the bottom seal’s performance. | Check local code |
| Swing Clearance | Map the complete arc of the swing panel, including furniture, equipment, people, carts, and adjacent doors. | Keep the full operating path clear. The required depth depends on the door width and opening angle; verify it from the project-specific door schedule. | A swing-slide door may need clearance in swing mode even when it normally operates by sliding. | Prepare floor plan |
| Sliding Travel and Side Space | Measure the unobstructed wall length beside the opening and check for columns, pipes, cabinets, and return walls. | Provide a sliding pocket or side run at least equal to the door panel travel, plus the frame and service access required by the selected system. | Insufficient side space can reduce the clear opening or force the door panel into nearby services and finishes. | Confirm layout |
| Electrical Supply | Confirm supply voltage, circuit location, isolator position, cable route, and whether emergency power is required. | Use the electrical rating specified for the chosen operator. Many control systems use low-voltage control wiring, while the mains input varies by system and region. | Incorrect voltage, inadequate earthing, or inaccessible isolation can create commissioning, maintenance, and safety problems. | Licensed electrician |
| Safety Sensors and Detection | Check sensor mounting locations, detection zones, approach direction, and possible interference from reflective surfaces or moving equipment. | Provide safety detection for the swing area and sliding closing zone as required by the selected operator and applicable safety standard. | Sensors help prevent contact with users, carts, equipment, and obstacles during opening and closing. | Safety test required |
| Traffic and Operating Cycle | Estimate users per hour, trolley or bed traffic, peak periods, opening frequency, and expected operating hours. | Classify the door as light, medium, or high traffic based on the project’s usage. High-cycle areas require a suitably rated operator, hinges, rollers, and seals. | Traffic level affects durability, motor capacity, maintenance intervals, opening speed, and the required safety package. | Usage assessment |
| Air Pressure and Environmental Conditions | Check pressure differences, temperature, humidity, dust, wash-down exposure, wind, and the presence of corrosive chemicals. | Record the expected indoor temperature and humidity range. Select compatible materials and seals for wet, cleanroom, healthcare, food, exterior, or corrosive environments. | Pressure differences and harsh environments can increase operating force, reduce sealing performance, and shorten component life. | Environmental review |
| Fire and Smoke Strategy | Determine whether the opening is located in a fire compartment, smoke-control boundary, escape route, or protected corridor. | Fire-rated or smoke-control performance must be based on a tested and listed door assembly. Do not modify a rated assembly without approved documentation. | A standard automatic swing-slide door may not provide the fire or smoke performance required for a protected opening. | Authority approval |
| Emergency Egress | Confirm the direction of escape, manual release method, power-failure behavior, and access-control interface. | The door must achieve the required safe state during power loss and emergency release conditions for the building’s occupancy type. | Access control must never prevent lawful evacuation or conflict with panic hardware and emergency exit requirements. | Life-safety review |
| Water, Drainage, and Cleaning | Check whether the opening is exposed to hose cleaning, floor drainage, splash water, or standing moisture. | Keep electrical components protected from water exposure and coordinate the threshold, floor slope, seals, and drainage channel before installation. | Poor drainage can cause corrosion, slippery surfaces, seal deterioration, and repeated operator faults. | Coordinate trades |
| Maintenance Access | Provide access to the operator, controller, sensors, fasteners, batteries, and adjustment points. | Allow safe service access without dismantling fixed ceilings, wall finishes, or adjacent equipment. | Accessible maintenance reduces downtime and supports routine inspection, cleaning, adjustment, and safety testing. | Include service zone |
| Final Commissioning | Test opening speed, closing speed, force, obstacle detection, manual operation, emergency release, and access-control signals. | Commission the complete installed assembly under normal and fault conditions, then record the test results and handover settings. | Site conditions can change after installation; final testing confirms that the door operates safely in its actual environment. | Document results |
