&he +*1 !ational Structural Code o' the Philiines, Volume *, 5th Edition, includes and elaborate the meaning o' 6FAI#%"E7.

As de'ined, FAI#%"E is an unaccetable di''erence bet(een e2ected and obser)ed er'ormance. It includes catastrohic structural collase, but also I!C#%-ES er'ormance roblems that are not necessarily catastrohic or li'e3threatening, including 67ser)iceability 67ser)iceability roblems such as distress, e2cessi)e de'ormation, remature deterioration o' materials, lea8ing roo's and 'acades, and inade0uate interior en)ironmental control systems7. systems7.

Section *+ : -e'initions In the e)ent o' a signi'icant 'ailure, the arties tyically retain e2erts to determine the cause o' the ercei)ed 'ailure. 9ccasionally a 'ailure results 'rom a single condition, but tyically, 'ailures result 'rom a combination o' mista8es, o)ersights, miscommunications, misunderstandings, ignorance, lases, slis, incometence, intentional )iolations or non3 comliance, and inade0uate 0uality assurance.

Section *+ : -e'initions &he causes 'or these conditions )ary, but may include simle mista8es such as sending in'ormation to a structural engineer (hen it should ha)e been sent to the architect;, conclusions based on 'aulty assumtions, an emloyeeect to the monitoring o' the 4uilding 9''icial. -ata roduced by the instruments shall be made a)ailable to the 4uilding 9''icial or the Philiine Institute o' Volcanology and Seismology P@IV9#CS; on re0uest.
