Store construction continues after a refrigeration survey. A wall may receive tile, a column may grow with cladding, a doorway may narrow, the finished floor may rise, or utilities may move. If cabinet production uses the earlier measurement without a controlled review, the conflict appears during delivery or installation.
A site measurement change log preserves the baseline, identifies what changed, shows which equipment is affected, and records who released the revised information.
Freeze the Survey Baseline
Identify the approved survey drawing, date, revision, surveyor, units, scale, and fixed datum. Record whether measurements were taken to unfinished or finished surfaces.
Keep original photographs and marked plans. The supermarket refrigeration project checklist provides the broader information set around the survey.
Avoid replacing the baseline file. A change log needs both before and after states.
Use Stable Reference Points
Choose building grids, structural columns, finished wall intersections, or other approved datums. Temporary studs, loose counters, stacked materials, and unverified chalk lines are weak references.
State the direction and endpoints of every measurement. "Wall length 4200" is incomplete without start point, end point, unit, surface, and elevation where relevant.
Photograph the tape or instrument position while preserving a wide context image.
Log One Change Per Record
Give each change a unique ID. Record date, location, baseline value, current value, difference, source, reason if known, photographs, drawing markup, affected equipment, owner, and status.
| Change Field | Example of Useful Detail |
|---|---|
| Location | Grid B4 to finished east wall |
| Baseline | Approved survey revision and value |
| Current condition | New measured value and method |
| Physical change | Tile, cladding, wall move, floor finish, utility relocation |
| Impact | Cabinet run, joint, service gap, aisle, doorway, pipe route |
| Decision | Accept, redesign, remeasure, hold, or site correction |
Avoid combining unrelated changes into one general site-update message.
Recheck Walls, Columns, and Recesses
Measure finished wall lengths, returns, corners, recess depths, column faces, skirting, protection rails, and overhead projections. Record whether finishes are complete.
A small change at each end of a long refrigerated run can affect module sequence and end clearances. Check cumulative dimensions rather than only individual bays.
Document out-of-square or stepped conditions through the approved survey method. Cabinet installers need real geometry, not a simplified rectangle.
Confirm Finished-Floor Information
Record finished-floor level, slope, thresholds, drains, floor joints, plinths, and changes between zones. State whether flooring is final or an allowance remains.
Long island or counter runs can reveal level variation. Qualified project teams determine leveling and installation responses; the change log only provides traceable measurements.
Recheck equipment height relationships where overhead shelves, signs, glazing, or service access depend on floor level.
Recheck Doorways and the Delivery Route
Measure clear width and height with doors, frames, closers, handles, guards, ramps, lifts, and turns installed. A structural opening on an early drawing may be larger than the final clear passage.
Use the commercial refrigeration delivery-path article to repeat route checks. Record removable components and responsible parties.
Avoid assuming a cabinet can be tilted or dismantled unless the supplier and handling plan confirm it.
Coordinate Utilities and Drainage
Mark actual electrical points, isolators, outlets, refrigerant pipe routes where relevant, drains, water points, data or controls, and penetrations. Record height and offset from fixed datums.
Compare with the current equipment and installation drawings. A utility point can be physically present yet conflict with panels, ventilation, service access, or cabinet joints.
Qualified electrical and refrigeration teams review capacities, connections, and compliance. The log should avoid inventing technical values.
Assess Impact by Equipment Structure
Different cabinets react differently to site changes. An open multideck along a wall, a combined island freezer in an aisle, a glass-door upright bank, and a straight-glass service counter each have distinct footprints, access, and joint conditions.
List exact product category, structure, application, installation type, model, and affected module. Avoid a broad note saying "all fridges move 50 mm."
Check customer side, staff side, doors or lids, cleaning, and service access.
Issue a Marked Revision
Update the drawing with change IDs and clouds or another agreed marking convention. Add revision, date, author, checker, approver, and distribution list.
Send the revision to buyer, designer, equipment supplier, installer, builder, electrical team, refrigeration team, and other affected parties according to project responsibility.
Request receipt confirmation. A file sent by email is not automatically incorporated into production.
Establish a Production Release Gate
Before cabinet production or final order release, list open measurements and state whether each blocks release. Define the last acceptable site verification date under the project schedule.
The supplier should identify which dimensions are fixed after release and what change consequences apply. Keep those terms with the approval.
Avoid verbal release when unresolved changes remain on a different drawing revision.
Handle Late Changes Explicitly
When a change occurs after production release, open a new impact record. Review equipment already built, packaging, delivery route, utilities, site work, schedule, and commercial consequences.
Possible responses include site adjustment, cabinet modification, layout revision, phased installation, or another agreed solution. The responsible project team chooses the response.
Preserve the rejected alternatives and decision basis where useful.
Feed Back the As-Installed Condition
After installation, update final positions, dimensions, utility routes, and equipment asset codes. Link snag closeout and photographs.
The as-installed record supports future store remodels and replacement planning. It should remain distinct from the pre-production change log while referencing the same IDs.

Common Questions
Is a site photo enough to approve a dimension change?
Use a recorded measurement, fixed references, method, marked drawing, and responsible approval. Photos support context.
Which measurement controls when drawings differ?
The project document hierarchy and approved revision determine the controlling information.
Can production start with open dimensions?
The supplier and project team need an explicit release decision, impact assessment, and responsibility for remaining risk.
What if the finished floor is incomplete?
Record the current level and confirmed finish allowance, then schedule verification under the project plan.
Share Changes Before Release
Use the XCCOLD contact page to send the baseline revision, fixed datums, marked changes, photographs, affected cabinet structures, utility updates, open items, and required production decision. Timely change control is cheaper than discovering the conflict at installation.
