Pamene mizinda padziko lonse lapansi ikuthamangira kukweza zida zokalamba ndikumanga matawuni atsopano,zitsulo mapepala miluzakhala njira yosinthira masewera-ndi liwiro lawo loyika mwachangu lomwe lidakhala dalaivala wamkulu wotengera ana awo, kuthandiza makontrakitala kuchepetsa nthawi ya projekiti mkati mwa ndandanda yolimba yomanga mizinda.
Zambiri zamakampani zochokera ku Global Steel Construction Association (GSCA) zikuwonetsa kuwonjezeka kwa 22% pachakapepala mulukugwiritsidwa ntchito pama projekiti akumatauni mu 2024, kukulitsa njanji zapansi panthaka, kukonzanso magombe amadzi, ndikukumba mozama kwa maziko okwera. Mosiyana ndi miyambo yosungira konkriti yomwe imafunikira milungu ingapo yakuchiritsa,milu yamakono yachitsulo—nthawi zambiri zomangidwiratu kuti zikwaniritse miyeso yeniyeni ya projekiti — zitha kuyendetsedwa pansi pamtunda wa 15 mpaka 20 liniya mita patsiku, ndikudula nthawi yomanga pamalowo ndi 30% pafupifupi.
"Kumanga m'matauni sikudikirira - kuchedwa kumatanthauza kukwera mtengo komanso kusokoneza anthu ambiri," atero a Maria Hernandez, mainjiniya wamkulu wa zomangamanga pakampani yomanga ya EuroBuild ku Madrid. "Pantchito yathu yowonjezera metro yaposachedwa ku Barcelona, tikusintha ndikulumikizanaotentha adagulung'undisa zitsulo pepala milukwa makoma omangira ngalandeyo adametedwa masiku 12 kuchokera pakukumba. Izi ndizofunikira kwambiri ngati mukugwira ntchito m'malo okhala ndi anthu ochepa. ”
Pempho lama sheet pilesamapitilira liwiro. Zovala zawo zosagwirizana ndi dzimbiri (monga galvanization yotentha kapena ma polima) zimawapangitsa kukhala olimba kuti azigwiritsa ntchito nthawi yayitali, pomwe mapangidwe awo amalola kuti achotsedwe mosavuta ndikugwiritsanso ntchito m'ma projekiti amtsogolo-kugwirizana ndi zolinga zakukhazikika kwamatauni padziko lonse lapansi. Pakukweza kwamadzi ku Marina Bay ku Singapore, mwachitsanzo, milu yamasamba yomwe idakhazikitsidwa mu 2023 kuti akhazikitse malo omwe adalandidwanso adzagwiritsidwanso ntchito pachitetezo chapafupi ndi gombe mu 2025, kuchepetsa zinyalala ndi 40%.
Okonza mizinda akuwonanso ubwino wa magalimoto ndi maulendo a anthu. Ku Toronto, ntchito yokulitsa misewu kotala lapitalo idagwiritsa ntchito milu ya mapepala kuti amange makoma osakhalitsa m'malo ogwirira ntchito. “Chifukwa chakuti kuikako kunamalizidwa m’mausiku atatu okha, tinapeŵa kutsekedwa kwa misewu m’nthaŵi yachipambano—chinthu chimene sichikanatheka ndi makoma a konkire,” anatero wolankhulira wa Dipatimenti Yoona za Maulendo ku Toronto James Liu.
Opanga akulabadira kufunikira komwe kukukulirakulira popanga zatsopano. Kumayambiriro kwa mwezi uno, wopanga zitsulo waku Dutch ArcelorMittal adayambitsa mtundu watsopano wopepuka wamapepala womwe umakhalabe ndi mphamvu zambiri koma ndi 15% yosavuta kunyamula ndikuyiyika, kulunjika mapulojekiti am'matauni apakati pomwe makina olemera amakhala ochepa.
Akatswiri azamakampani akulosera kuti izi zichuluka kwambiri mu 2025, pomwe kutengera milu yamasamba kukuyembekezeka kukwera ndi 18% pomwe mizinda yaku Asia ndi Africa ikukulitsa ndalama zoyendetsera ntchito. "Kukhazikika m'matauni sikucheperachepera, ndipo makontrakitala akufunika njira zothetsera liwiro, chitetezo, komanso kukhazikika," adatero Raj Patel, katswiri wa zomangamanga ku GSCA. "Milu yamasamba imayang'ana mabokosi onsewo - ndipo gawo lawo pakumanga bwino kwamatauni ukukulirakulira."
