Quake work com­pleted

Kapiti News - - News -

Coun­cil’s work to iden­tify po­ten­tially earth­quake prone build­ings in the dis­trict is now com­plete.

The own­ers of 28 po­ten­tially earth­quake-prone build­ings have been no­ti­fied and ad­vised that they will need to ob­tain a seis­mic as­sess­ment of their build­ing for coun­cil to con­sider.

Reg­u­la­tory ser­vices group man­ager Natasha Tod said coun­cils have re­spon­si­bil­i­ties un­der the Build­ing Act 2018 to iden­tify po­ten­tially earth­quake-prone build­ings in their dis­trict.

“We’ve just fin­ished this first stage of build­ing pro­fil­ing us­ing MBIE’s pre­scribed earth­quake-prone build­ing method­ol­ogy.

“This ef­fec­tively iden­ti­fies build­ings or parts of build­ings that might be of con­cern and need fur­ther as­sess­ment.”

Ms Tod said Ka¯ piti was an area of high seis­mic risk with deep soft soils which can pose chal­lenges for build­ings built here.

“En­gi­neer­ing un­der­stand­ing has de­vel­oped over time and de­sign codes have changed as a re­sponse.

“Build­ings built to previous en­gi­neer­ing de­sign codes will gen­er­ally not be as seis­mi­cally ro­bust as a new build­ing.

“The own­ers of the re­cently iden­ti­fied po­ten­tially earth­quake-prone build­ings have been no­ti­fied and have 12 months to ob­tain a seis­mic as­sess­ment of their build­ing for coun­cil to con­sider.

“An ex­ten­sion for a fur­ther 12 months can be sought.

“The coun­cil then de­cides if the build­ing is earth­quake­prone and is­sues a no­tice which must be dis­played on the build­ing if it is.

“But, even though a build­ing is iden­ti­fied as be­ing po­ten­tially earth­quake-prone doesn’t mean it is earth­quake­prone, which is why fur­ther seis­mic as­sess­ment is re­quired to de­ter­mine this with cer­tainty.”

The strength of old build­ings are ex­pressed as a per­cent­age of new build­ing strength (%NBS) and where this falls be­low 34 per cent, the build­ing is clas­si­fied earth­quake-prone.

Coun­cil’s earth­quake­prone build­ing project is en­ter­ing the next phase of de­cid­ing if build­ings pre­vi­ously iden­ti­fied as po­ten­tially earth­quake-prone are earth­quake-prone and is­su­ing no­tices re­quir­ing up­grad­ing of the build­ing.

To date, five no­tices have been is­sued. When an earth­quake-prone build­ing no­tice is is­sued, the build­ing is added to the pub­lic reg­is­ter ad­min­is­tered by MBIE at www.build­ing.govt.nz/ man­ag­ing-build­ings/ man­ag­ing-earth­quake-proneb­uild­ings/epb-reg­is­ter/
