design sol utions and any sources of deterioratio n that<br />
may be of significance in conjunction with future maintenance.<br />
Acceptance Inspecti on shall also be per<strong>for</strong>med after maj~ r rehabilitat<br />
ion or maintenance works have been carried out on a "bridge.<br />
The purpose of the Warranty Inspecti on is to chec k that a ny work<br />
done during the construct ion phase, or repairs following<br />
theAcceptance Inspection are acceptable, and that new damage,<br />

Any new sources of deterioration of relevance <strong>for</strong> later maintenance<br />
should also be identifi ed.<br />
