Glass Railing Quote Validity and Change Order Policies

t343-46

A glass railing quote is valid only for a stated period and for the specification it describes, so any change to design, measurements, glass type or finish requires a written change order. Each change order is documented, approved by you in writing, and only then added to production.

What a glass railing quote covers

A quote for glass railings is based on a specific set of details: the railing length, height, the number of posts or clamps, the glass thickness and type, the handrail or top profile, and the finish. It also reflects the measurements taken on site. Because each railing is made to measure, the quote is tied to that exact scope.

Before you approve, check that the written specification matches what you discussed. If something is missing, ask for it to be added now, while changes are still simple.

How long a quote stays valid

Every quote states its validity period in writing. Once that period passes, material costs, glass availability and factory scheduling may have changed, so the quote may need to be reissued before work starts. Approving within the stated window helps keep the scope and timing as agreed.

If your project is delayed, tell us early. We can confirm whether the existing quote still applies or whether a short update is needed.

What triggers a change order

A change order is needed whenever the work departs from the approved specification. Common triggers include:

Different railing height or length after on-site re-measurement
Switching glass thickness, type or edge finish
Changing the handrail, clamps or fixing method
Adding gates, corners or extra sections
Changing the powder coating or finish colour

Small verbal requests during a site visit should still be confirmed in writing.

How a change order is processed

The process is simple. The requested change is described, a revised written specification is prepared, and the effect on scope and schedule is stated. You review and approve the change order in writing before production of the affected part begins. Work that has already been completed according to the earlier approval is handled separately so nothing is lost or duplicated.

Keeping one written record for each change prevents misunderstandings later, especially when several people on a project are involved.

Measurement and site conditions

Glass railings are sensitive to exact dimensions. If the building structure differs from the drawings, the railing may need adjustment. We measure on site before finalizing, and any discovered difference is raised as a change to be approved. Floor levels, wall finishes and balcony edges should be checked together with your contractor so the measurements reflect the real conditions.

Where safety requirements apply, exact values are confirmed with the engineer. The Israeli railing standard SI 1142 is one reference point for the design team to review.

Keeping changes under control

The best way to limit change orders is to finish decisions early. Settle the glass type, handrail, fixing method and finish before the specification is approved, and confirm measurements after the walls are finished. Share photos and drawings with everyone involved, including the architect or building committee, so changes are caught early.

Frequently asked questions

Does a quote for glass railings expire?

Yes, each quote states a validity period. If it lapses before you approve, we can confirm whether the price basis still holds or issue an updated quote.

Do small changes need a formal change order?

Yes, any change to the approved specification should be recorded in writing, even if it seems minor. This keeps production and billing clear.

What if the measurements on site are different from the drawings?

We re-measure on site and raise any difference as a change for your written approval before production of the affected section.

Can I change the glass type after approving the quote?

You can, but a change order is required. We will explain how it affects the scope and schedule before you confirm.

Common mistakes to avoid

Approving a quote without checking the measurements or specification, and then requesting verbal changes that are never written down. Always confirm each change in writing before work proceeds.

Our recommendation

Settle the glass type, handrail and finish before approving, and have measurements confirmed after the walls are complete. Keep every change in a single written change order so the project record stays clear.

Summary

Glass railing quotes are valid for a stated period and for a specific specification, and any change requires a written change order approved before production.
