Kubalwa cishe u-60% wawo wonke umsebenzi emakethe ye-steelwork yesakhiwo yase-UK, umkhakha wezakhiwo zezimboni ezinesitezi esisodwa ube umatasatasa emashumini ambalwa eminyaka adlule futhi ukhombisa uphawu oluncane lokuhlehla.
Lezi zakhiwo zinezinhlobonhlobo zokusetshenziswa, okuhlanganisa izindawo zokusebenzela, izimboni kanyeizitolo zokudayisaukubala ezimbalwa, kodwa iningi lakhiwe njengendawo yokugcina impahla, evame ukubizwa ngokuthi 'amashede'.
I-Structural steelwork iyisixazululo esithandwayo sohlaka sesikhungo sokusabalalisaukwakhiwa, ngesabelo semakethe esidlula u-90%.Insimbi inikeza inani lezinzuzo, njengeisivininiwokwakha kanye nekhono lokudala kahle isikhathi esideizikhala zangaphakathi, ezibaluleke kakhulu ezindaweni zokugcina izimpahla.
Izindleko nokulethwa kwezikhungo zokusabalalisa zibe ngcono kakhulu ezikhathini zamuva nje, ngenxa yengxenye encane yokusetshenziswa kahle kwamafreyimu ephothali ngosonkontileka abasebenza ngensimbi abenza umsebenzi wokwakha.dweba futhi wakheisivumelwano.
Izinzuzo zokuklama nokwakha zihlanganisa iqiniso lokuthi usonkontileka wensimbi angakwazi ukuhlehlisa ngokushesha nangempumelelo aisikhungo sokusabalalisauhlaka lwensimbi.
"Sikhetha lolu hlobo lwenkontileka njengoba singasebenzisa ulwazi lwethu olukhulu lwezikhungo zokusabalalisa ukuze siqinisekise ukuthi uhlaka lwensimbi lusebenza kahle ngangokunokwenzeka," kusho u-Caunton Engineering Senior Structural Engineer Colin Winter.
Isibonelo salo msebenzi iphrojekthi yeCaunton Engineering eKingston Park, ePeterborough, lapho iklame khona,eyenziwe, ihlinzeke futhi yakha izikhungo ezintathu zokusabalalisa egameni leGlencar Construction.
Ithengwe unjiniyela iFirethorn Trust ekuqaleni kwalo nyaka, indawo engamahektare angama-21 iseduze nabahlali abakhona i-Amazon, IKEA kanye ne-DART futhi inikeza ukuxhumana okuhle njengoba iphakathi kwamamayela amabili ukusuka ku-A1(M) ekuhlanganeni kwe-17.
Umqondisi Wokuthuthukiswa KweFirethorn Trust u-Paul Martin uthi: “Sihlabeke umxhwele ngomlando omningi we-Glencar ekuletheni izinsiza ezisezingeni eliphezulu zalolu hlobo, futhi sisebenzisana eduze nethimba ukwenza umbono wethu nge-Peterborough South uphile.
“Lokhu okucaciswe kakhulu, i-net-zero carbon development yakhelwe ukuqhubeka nokuqhuba ukutshalwa kwezimali kanye namathuba omsebenzi endaweni eseyingesinye sezifunda ezikhula ngokushesha e-UK.Lolu hlelo luzohlangabezana nesidingo esikhulayo sabahlali sezindawo zekhwalithi, ezisimeme nezivumelana nezimo.”
Idala indawo ecishe ibe ngu-46,450m² yendawo yezinto zokusebenza kuwo wonke amayunithi amathathu, uhlelo luzolethwa ku-net-zero carbon esakhiwayo futhi luqondise isilinganiso 'Esihle kakhulu' se-BREEAM.Ingqalasizinda esimeme izobandakanya ngaphezu kuka-3,700m² wama-photovoltaic arrays njengokujwayelekile, izindawo zokushaja izimoto zikagesi ezingu-48, kanye no-15% wezibani zophahla.
Zontathu lezi zakhiwo zingamafreyimu ephothali futhi anomklamo nomqondo ofanayo, nakuba wonke anosayizi abahlukene.Isakhiwo esikhulu kunazo zonke esakhiweni, esaziwa ngokuthi iBuilding 300, naso sasiyisakhiwo sokuqala ukwakhiwa.Lolu hlaka lwephothali luqukethe ububanzi obuyi-31m ububanzi futhi buyi-168m ubude.
Njengazo zonke izakhiwo ezikulesi siza, amakholomu asekelwe ezisekelweni ezinqwabelene futhi amalungu omjikelezo ahlukaniswe ngezikhala eziyi-8m.Ngaphakathi, ahlelwe ngendlela yokucushwa kwe-hit-and-miss, okusho ukuthi kunekholomu njalo nge-16m eduze kwemigqa yesigodi, okudala indawo evulekile yohlelo ngaphakathi kwesakhiwo.
Amakholomu esigodi amelela izakhi zensimbi ezisinda kakhulu kuphrojekthi njengoba zinesisindo esingu-3.5t lilinye.
Wonke amabhilidi anophahla olugobile, olwakhiwe lwaba nezingxenye zamapulangwe ezihlukene phakathi kwezikhala.Ngaphakathi kophahla lweSakhiwo esingu-300, i-span ngayinye yayidinga izingxenye ezintathu ezinezinhlangothi ezintathu, ezazihlanganiswe phansi bese ziphakanyiswa zibe yingxenye ephelele engama-31m ubude.
Ingxenye eyodwa ewumpheme yesakhiwo esingu-300 inesakhiwo samahhovisi esinezitezi ezimbili, esinendawo yokugcina impahla ngaphakathi kwesitezi saso esingaphansi.
“Ibhilidi ngalinye kulawa amathathu linendawo yamahhovisi, futhi lezi zindawo zaba yizingxenye zokuqala ezakhiwa esakhiweni ngasinye njengoba ziyizindawo zesakhiwo ezinomsebenzi omningi wemisebenzi eqhubekayo,” kusho uMphathi weCaunton Engineering Contracts u-Adrian Downing. .
“Uma amahhovisi esewakhiwe awabange esadinga imisebenzi yesikhashana ngaphambi kokuthi kuqale uhlaka, ngoba abeziphilisa ngokwawo ngoba ama-floor awo ahlanganisiwe kanye nezinsimbi zawo kunikeza uzinzo.”
Amabhulokhi amahhovisi ayizakhiwo ezingenakholamu ububanzi obuyi-10m, ezakhiwe ngemishayo yensimbi esekela ukudekhiswa kwensimbi kanye nophahla lukakhonkolo.Ukwengeza ukuguquguquka okuthile kwesikhathi esizayo kuphrojekthi, izinga eliphezulu linesivalo esiyinhlanganisela (uphahla), esingaguqulelwa kwesinye isitezi sehhovisi.Ukuze wenze lokhu kuvikeleke esikhathini esizayo, izisekelo zesakhiwo ziklanywe ngomthamo owengeziwe.
Incane kancane futhi ibekwe eduze ne-Building 300, i-Building 200 iyona elandelayo ezokwakhiwa.Lesi sakhiwo sinama-spans amathathu ububanzi obungama-30m futhi ubude bungu-136m.Ngokufana nomakhelwane wayo omkhulu, izikhala zophahla olugobile nazo zakhiwe zinamalungu anezinhlangothi ezintathu.Lesi sikhungo sokusabalalisa siphinde sibe nesakhiwo samahhovisi esinezitezi ezimbili.
Isakhiwo sesithathu nesincane kunazo zonke, esaziwa nge-Building 100, siwuhlaka lwephothali olunwetshiwe oluphindwe kabili, oluyi-112m ubude.I-span ngayinye ingu-37m ububanzi futhi iqukethe amalungu ensimbi anezinhlangothi ezine akha uphahla lwalo olugobile.
Njengoba kunamalungu amaningi ensimbi adingekayo ngesikhathi ngasinye, inqubo yokumisa uphahla lwalesi sakhiwo ibihluke kancane.Isebenzisa okhrayini abahambayo ababili, iyunithi ngayinye yayiphakamisa izingxenye ezimbili ezazihlanganiswe kusengaphambili futhi izibambe endaweni, kuyilapho kwenziwa uhlaka olumaphakathi ukuze kuqedwe sonke isikhathi.
I-Building 100 inebhlokhi yehhovisi enesitezi esisodwa, kodwa ngokuguquguquka okufanayo okwakhelwe ngaphakathi, lokhu kungashintshwa kube yizitezi ezimbili uma kudingekile.
Izikhungo ezintathu zokusabalalisa i-Kingston Park kumele zibe seziqediwe ekupheleni konyaka.
