Semaguta epasirese anomhanya kusimudzira zvivakwa zvekuchembera uye kuvaka zvivakwa zvitsva zvemudhorobha,simbi mapepa mirwivabuda semhinduro inoshandura mutambo-nekukurumidza kumisikidza kwavo kuita mutyairi akakosha wekugamuchirwa, kubatsira makondirakiti kutema nguva yeprojekiti pakati pezvirongwa zvekuvaka maguta.
Indasitiri data kubva kuGlobal Steel Construction Association (GSCA) inoratidza kuwedzera kwe22% gore-pamusoro-goresheet pilekushandiswa kwemapurojekiti emudhorobha muna 2024, kuwedzera kwenzira yepasi pevhu, kuvandudzwa kwemvura, uye basa rekuchera rakadzama renheyo dzepamusoro. Kusiyana nechinyakare kongiri kuchengetedza zvimiro zvinoda mavhiki ekurapa nguva,mirwi yemazuva ano yesimbi-kazhinji inogadzirwa kuti isangane nemapurojekiti chaiwo-inogona kuendeswa pasi nechiyero chegumi nemashanu kusvika makumi maviri emamita mutsara pazuva, ichicheka pane-saiti nguva yekuvaka ne30% paavhareji.
"Kuvakwa kwemadhorobha hakumirire - kunonoka kunoreva kukwira kwemitengo uye kukanganisa kwakawanda kuvagari," akadaro Maria Hernandez, mainjiniya epamusoro pakambani yekuvaka yeMadrid EuroBuild. "Pachirongwa chedu chekuwedzera metro muBarcelona, ichichinjira kune inopindiranainopisa yakakungurutswa simbi mapepa mirwinokuti mugero unochengeta madziro akaveurwa mazuva gumi nemaviri kubva pachikamu chekuchera. Izvo zvakakosha kana uchinge uchishanda munzvimbo dzakaomesesa dzisingakwanisi kuwana. ”
Chikumbiro cheiwe mapepa mirwiinowedzera kupfuura kumhanya. Mabatiro adzo asingadziviriki (sekupisa-dip galvanization kana kurapwa kwepolymer) anoita kuti agare kwenguva refu yekushandiswa kwezvivakwa zvenguva refu, nepo modular dhizaini inobvumira kubviswa nyore uye kushandiswazve mumapurojekiti emangwana-kuenderana nezvinangwa zvekusimudzira maguta. MuSingapore's Marina Bay kumberi kwemvura kukwidziridzwa, semuenzaniso, mapepa akaiswa muna 2023 kuti agadzikane ivhu rakadzoserwa richadzoserwa purojekiti yepedyo yekudzivirira yemahombekombe muna 2025, kuderedza marara ne40%.
Vanoronga maguta vari kuonawo mabhenefiti ekufambiswa kwemigwagwa uye kuwana veruzhinji. MuToronto, chirongwa chekuwedzera migwagwa chikamu chapfuura chakashandisa mirwi yemashizha kuvaka madziro ekuchengetedza kwenguva pfupi munzvimbo yebasa. “Nemhaka yokuti kuiswa kwakapedzwa muusiku hutatu chete, takadzivisa kuvharwa kwemigwagwa yakazara mukati memaawa akakwirira zvikuru—chimwe chinhu chingadai chisingabviri nemadziro ekongiri,” akadaro mutauriri weDhipatimendi Rezvokufambisa reToronto, James Liu.
Vagadziri vari kupindura kudiwa kuri kukura nekuvandudza zvimwe. Kutanga mwedzi uno, mugadziri wesimbi wechiDutch ArcelorMittal akatanga mutsva wepepa uremu huremu hunoramba huine simba rakawanda asi zviri nyore kutakura nekuisa 15%, zvichinangana nemapurojekiti emudhorobha umo michina inorema isingakwanisi.
Nyanzvi dzemaindasitiri dzinofanotaura kuti maitiro achawedzera muna 2025, nekutorwa kwemapepa kunotarisirwa kukura neimwe 18% sezvo maguta eAsia neAfrica ari kusimudzira mari yezvivakwa. "Kugariswa kwemaguta hakusi kudzikira, uye makondirakiti anoda mhinduro dzinoyedza kumhanya, kuchengetedzeka, uye kusimba," akadaro muongorori wezvezvivakwa weGSCA, Raj Patel. "Mirwi yemashiti inoongorora mabhokisi ese iwayo - uye basa rawo mukugadzira zvivakwa zvakanaka zvemaguta richangokura."
