The Pre-Quotation Site Measurement Protocol for Commercial Cleaning Equipment

Scope and assumptions

This protocol creates a repeatable pre-quotation survey for facility, engineering, environmental services, procurement, distributor and cleaning-contractor teams.

The protocol does not certify structural capacity, electrical installation, wastewater disposal, fire safety, chemical compatibility or machine performance. Those decisions remain with the facility's authorized specialists and the instructions for the exact supplied equipment. Site rules and applicable codes take priority over this general method.

Use metric units consistently. Identify every measurement by site, floor, route, point ID, date and measurer. Record model, revision, battery, attachments and options separately; a family name is not a configuration.

Measure six envelopes, not one width

A machine can pass through a door and still fail the route because its squeegee, turning path, operator position or service panels need more space. Build the survey around these envelopes:

Do not substitute one envelope for another. Overall width may omit a wider squeegee, a transport state may remove working parts, and a parked machine may need more clearance for daily care.

Survey tools and record control

Prepare the route plan before entering candidate data. Use suitable calibrated distance and slope tools, a floor plan, point labels and an approved method for recording lift or floor ratings. Follow site photography rules.

For every critical dimension:

1. Assign a point ID on the floor plan.
2. Measure the clear opening at the narrowest usable point, not the nominal architectural size.
3. Repeat or independently check the measurement.
4. Photograph the point with a visible ID and scale where permitted.
5. Record obstructions, approach direction, operating state and time-dependent restrictions.
6. Identify the source and revision of the candidate envelope used for comparison.
7. Apply the clearance margin approved by the facility and equipment owner.

There is no universal clearance margin. Door movement, uncertainty, projecting parts, visibility and traffic determine the allowance. An exact arithmetic match is not evidence of fit.

The pre-quotation measurement worksheet

Use one row for each constraint, even when several points have the same nominal size.

Add a status column with measured, source pending, trial required, fail or approved for quotation. Do not use pass when the candidate envelope or configuration is still unverified.

Measure access and cleaning reach

Doors, gates and lifts

Measure the opening actually available, including stops, hardware, bollards, guards, mats and limited opening angle. Record approach and exit space because a machine may fit straight through but fail to align.

For lifts, record door opening, cab dimensions, permitted loading orientation, sill gap, floor-level difference, door timing and load rating. Include credible lift-travel mass, accompanying people and liquid restrictions. Use the operating-weight and access load plan for that review.

Aisles, rack ends and dead ends

Measure at every height where machine, attachment or operator can contact an obstruction. Guards, pallets, pipes, columns and staging often create the real minimum. Record normal operations, not an empty aisle.

At each critical turn, draw entry, exit, inner corner and outer obstructions. Confirm whether the squeegee or side tool remains deployed. If exact turning data is unavailable, mark trial required and test the quoted unit.

Under racks or furniture, measure underside height and clear reach depth from the aisle edge. Record guards, uprights, stored goods and joints. State the inaccessible strip and assign it to another method.

Edges and remaining manual work

Measure edges, columns, corners, dock edges, entries and fixed obstacles. Compare the cleaning path, not just the body, and identify route sections outside the machine method.

Measure floors, slopes and transitions

Record floor material, coating condition, joints, cracks, holes, grates, drain covers, thresholds, mats, cables and low obstacles. Note where water could collect or move into occupied traffic. Floor compatibility and recovery must be tested separately; visual material identification is not proof that a brush, pad or chemical is suitable.

Calculate gradient consistently:

Gradient (%) = vertical rise / horizontal run x 100

Record whether the value is longitudinal or cross slope. Add ramp length, top and bottom transitions, surface condition, drainage, edge protection and stopping points. Do not compare the measurement with copied or unverified gradeability claims. Require approved model-specific limits for operating, transport, stopping and parking states.

Structural capacity is a separate gate. Obtain authoritative floor, cover, grate and lift ratings, then provide configured mass and wheel-load evidence to the responsible reviewer.

Map the complete service cycle

The service route begins when the operator collects the unit and ends when it is cleaned, charged and ready for handover. Walk and time the following sequence:

storage -> pre-use inspection -> fill -> cleaning route -> refill if required
-> drain -> rinse and daily care -> charging -> fault quarantine or handover

Measure hose and cable paths, not straight-line distance. Record water connection, wastewater destination, splash control, drain height, hose reach, lifting requirement and rinse space. Confirm that fill and drain work follows facility route-separation rules.

Identify the exact battery and charger before evaluating supply, plug, circuit, cables, ventilation, separation and fire controls. Facility electrical and safety owners must approve the charging plan.

Storage must accommodate the parked envelope plus access for inspection, drying and charging. Add security, ambient limits, spill response, chemical separation and a quarantine position for a faulted unit. In healthcare settings, the CDC cleaning-equipment guidance describes dedicated preparation, storage and reprocessing infrastructure; each facility must apply its own infection-control and building requirements.

Run the comparison and route trial

For each dimension, calculate:

Arithmetic clearance = measured clear site dimension
                     - verified candidate envelope in the same state and direction

Classify the result only after applying the facility-approved margin and measurement tolerance. A positive number is not automatically a pass.

Then conduct a representative trial of the exact quoted configuration. Include the narrowest door, most restrictive turn, rack end, dead end, lift or transition where permitted, normal traffic control, fill/drain route, parking and daily-care tasks. Record every contact, repositioning maneuver, attachment removal, traffic interruption and uncleaned edge. A clean straight pass in an open area does not validate the full route.

Acceptance and failure boundaries

Quotation approval is not final equipment acceptance. Use a separate sample test to confirm cleaning, recovery, runtime, operator handling and maintenance under representative conditions.

Connect the survey to ELEREIN E-series data

These figures do not establish minimum aisle width, turning radius, under-rack reach, ramp capability, operating weight, floor loading or transport dimensions. Net weight must not be used as loaded weight. The E60 is a walk-behind floor scrubber and the E100 and E130 are ride-on floor scrubbers; site measurements must still validate the full operating and turning envelope.

Buyer evidence checklist

• Dated, revision-controlled route plan with point IDs and direction of travel
• Instrument, measurer, units, repeated measurements and photographs for critical points
• Exact quoted model, format, battery, attachments, squeegee and configuration
• Static, operating, turning, transition, service and transport envelope sources
• Doors, corridors, rack clearances, dead ends, lifts and turning-box records
• Floor, joint, threshold, cover, grate, slope and structural-approval records
• Fill, drain, rinse, wastewater, charging, storage and fault-quarantine plans
• Traffic observations, barriers, emergency-route protection and cleaning window
• Edge-work map showing tasks assigned to other equipment or manual methods
• Representative trial plan, pass/fail criteria, exceptions and named approvers

Limitations

Measurements change when doors, racks, stock, barriers, utilities or traffic patterns change. Product dimensions can change with options or revisions. Re-survey any critical point after site alteration, and recheck the candidate after a configuration change. This protocol does not establish cleaning quality, chemical compatibility, drying, safe slope operation or structural adequacy.
