A quote is based on the site as understood at the time.
If the site changes, the quote may need to change.
That does not mean the original quote was wrong. It means the project is no longer the same project.
In construction, walls move. Ceilings change. Cabinets become smaller. Rooms change purpose. TV positions move. Internet routes shift. Electrical plans are revised. A client decides to add cameras, remove a music zone or change the entertainment area.
Each of those changes can affect technology.
The quote follows the design
AV, CCTV, Wi-Fi and smart-home quotations are tied to assumptions.
The number of points. The cable routes. The equipment location. The room use. The wall finish. The cabinet space. The access to ceilings. The number of visits. The handover expectation.
When those assumptions change, the quote should be reviewed before work continues blindly.
Ignoring the change does not save money.
It usually delays the cost conversation until later.
Small building changes can have large technology effects
A TV moving one metre may need a different conduit route.
A bulkhead changing shape may affect speaker positions.
A cabinet losing depth may affect equipment choice.
A gate position moving may affect intercom cabling.
A ceiling detail changing may affect Wi-Fi access point serviceability.
To another trade, the change may look small.
To the technology system, it may be significant.
A review prevents surprise extras
Most clients do not enjoy variation claims.
Neither do good contractors.
The best way to avoid unpleasant extras is to review the quote when the site changes, not after the work is already done.
If the change has no cost impact, everyone can move forward confidently.
If it does have a cost impact, the client can decide before the team spends the time.
That is fairer than discovering it at the end.
Rechecking protects performance
Site changes are not only a pricing issue.
They can affect performance.
Wi-Fi coverage, camera views, speaker balance, ventilation, remote control reliability and cable replacement access can all be affected by construction changes.
The review is not only about protecting the quote.
It is about protecting the final system.
DG Technologies would rather stop and check
On a serious project, momentum matters.
But so does judgement.
If something changes on site, DG Technologies would rather pause long enough to confirm the design than continue with an outdated assumption.
That habit can feel slower in the moment.
It is usually faster than fixing the wrong installation later.
