Glass cleaning for phased developer handovers

Make the handover package the unit of work

Start with the project’s actual release sequence. A public lobby might open before upper floors; one building might be occupied while another remains behind construction fencing. Give each released area a defined glass package instead of placing one final-clean item at the end of the overall programme. Include the relevant entrance, elevations, and interior glazing in that package, with the person who will accept it.

Match the package identifiers to the drawings and turnover schedule. The receiving property team should be able to find the same location in the cleaning notes, glazing information, and open-items list. A package can contain accepted panes and unresolved panes, but that distinction must remain visible when the developer describes the phase as handed over.

For a partially released elevation, show the boundary directly on the marked-up drawing. A statement such as north building complete can become misleading if only its entrance and lower lobby panes were in the first package. Use the same naming in the owner’s handover note. The receiving manager can then see whether upper panes are awaiting construction release, a different access method, or a glazing decision. Those distinctions remain useful when the active project and occupied property share the same facade.

Collect product information while the project team is available

Ask the glazing supplier for care instructions covering the glass products actually installed, including any exposed coating or applied film. Connect instructions to the relevant elevations or units. An unlabelled folder of product literature is difficult for a future manager to use and may include material that was specified but never installed.

NGA guidance calls for construction protection, while NGA/IWCA cleaning guidance addresses appropriate cleaning procedures and attention to manufacturer instructions. Preserve both the product information and the project’s known condition questions. The final-clean visit should not become the first point at which the receiving team learns that some panes need special care or further review.

Distinguish cleanliness from an unresolved glazing issue

During the pre-handover walk, describe visible concerns without deciding their cause prematurely. Note whether a mark appears on an accessible face, whether it remains after an agreed test clean, and whether the glazing team needs to inspect it. A scratched pane, a suspected internal issue, and removable construction film should not all remain under an item labelled dirty window.

Ask the appropriate project contact to decide the next step for each unresolved item. Routine washing, additional residue treatment, and a glazing defect review are different tasks. Acceptance of the washing does not establish that a separate defect has been resolved. Keep the observed condition, work performed, and outstanding decision in separate fields so the owner can follow the history.

Example: the first lobby opens while the second building continues

In a hypothetical two-building development, the first lobby is ready for public use while deliveries still pass through a neighboring entrance. The developer could release the lobby as a finished package and keep the delivery entrance in the construction package. That prevents ongoing trade traffic from repeatedly reopening the already accepted lobby clean.

If trade activity later enters the accepted lobby, describe any new soiling as a new event and decide whether another cleaning visit is required. Retain the first acceptance date. This is especially helpful when the property manager takes control midway through the project and needs to distinguish maintenance in an occupied area from remaining development work.

Give the receiving manager a short, traceable closeout

• Accepted areas: the package identifier, glass covered, and acceptance contact.
• Open items: the pane location, observed concern, and project contact responsible for the next decision.
• Care information: instructions matched to installed products and the locations where they apply.
• Future work: any unfinished phase or known trade activity likely to affect the accepted area.

Before closeout, ask the receiving manager to trace one accepted pane and one open pane through the package. If either is difficult to locate, simplify the naming. The objective is a practical maintenance handover that remains usable after the developer and construction team leave the site.
