Xa iBarbara Walker Crossing yaqalwa okokuqala ngo-2012, umsebenzi wayo ophambili yayikukugcina abakhweli kunye neembaleki kwi-Portland's Wildwood Trail kwingxaki yokuphepha ukugcwala kwi-West Burnside Road.
Yaba bubungqina boyilo lwe-aesthetically consciously consciously, ukudibanisa okuluncedo kunye nobuhle kuluntu oluxabisa (kwaye lufuna) zombini.
Igqitywe ngo-Okthobha ka-2019 kwaye yavulwa kwangaloo nyanga inye, ibhulorho yindlela yokuhamba yabahambi ngeenyawo ubude obuziimitha ezili-180 ecetywe ukuba igobe kwaye iyilelwe ukuba idibane nehlathi elijikelezileyo.
Yenziwe ngaphandle kwendawo yiNkampani yeNsimbi ePhakamileyo yasePortland engasekhoyo, yasikwa yangamacandelo amathathu aphambili, emva koko yathunyelwa ngeelori ukuya kwindawo.
Ukuhlangabezana neemfuno ezibonwayo kunye nezokwakha ezithetha ukusebenzisa imathiriyeli eya kuphumeza zonke iinjongo ezikhethekileyo zeprojekthi, zombini ubugcisa kunye nesakhiwo.Oku kuthetha ukusebenzisa imibhobho - kulo mzekelo 3.5″ kunye no-5″.corten (ASTM A847) iityhubhu yentsimbi yesakhiwo eyenzelwe izakhiwo ezifuna i-welded okanye ibholiti yentsimbi iyavezwa enye into edityanisiweyo yentsimbi kunye nentsimbi eluhlaza iyavezwa. Tshatisa i-canopy yehlathi.
U-Ed Carpenter, umyili kunye nomzobi okhethekileyo kwiindawo ezinkulu zofakelo lukawonkewonke, wathi wayeneenjongo ezininzi engqondweni xa ekhulelwa ibhulorho.Phakathi kwabo, ibhuloho kufuneka idityaniswe kumxholo wehlathi, nto leyo ukuqhubela phambili kwemvakalelo kunye namava omzila, kwaye kufuneka ibe yinto enqabileyo kwaye ibonakale ngokusemandleni.
“Ngenxa yokuba olona sukelo lwam lubalulekileyo yayikukuyenza ibhulorho ibe-ethe-ethe yaye icace, ndandifuna ezona zinto zisemgangathweni kunye neyona nkqubo ifanelekileyo yolwakhiwo—ngoko, iintsimbi ezintathu eziziintambo,” utsho uCarpenter, okwangumthandi wangaphandle. .Isebenza kwisixokelelwano esikhulu sendlela yasePortland iminyaka engaphezu kwama-40.” Usenokuyakha ngezinye izinto, kodwa imibhobho yentsimbi okanye imibhobho lukhetho olusengqiqweni.
Ukusuka kwimbono yolwakhiwo olusebenzayo, ukuphumeza konke oku akulula. UStuart Finney, injineli yezakhiwo kwi-ofisi yasePortland yefemu yobunjineli ye-KPFF kunye nomphathi weprojekthi yebhulorho yangaphambili, uthe ngempumelelo ukuwelda onke amacandelo kwiintlanganisela zeTYK apho yonke imibhobho exhasayo idibana khona mhlawumbi yayiyeyona nto inzima kakhulu. kwadala imingeni enzima kwiqela labakhi.
UFinney, obeqhelisela lo msebenzi kangangeminyaka engama-20 uthi: “Eyona nto ibalulekileyo ilungu ngalinye lahlukile.” Kwakufuneka badibanise yonke le mibhobho ukuze idityaniswe kwindawo enye, ukuze bakwazi ukufumana izinto zokuwelda ezaneleyo kuyo yonke imibhobho.
Ibhulorho yabahambi ngeenyawo kaBarbara Walker inqumla kwindlela yasePortland enezothutho eziphezulu iBurnside Road. Yaqala ukusebenza ngo-Okthobha wama-2019. UShane Bliss
Iiwelds kufuneka ziguqulwe ngokupheleleyo. Ukuwelda ngenene kunokuba yenye yezona ndawo zintsokothileyo kwimveliso.
I-Ferry's namesake, uBarbara Walker (1935-2014), uye waba ngundoqo kwiinzame zolondolozo lwasePortland iminyaka, kwaye unamandla endalo ngokwakhe. Udlale indima ebonakalayo kwiiprojekthi ezininzi zoluntu ePortland, kuquka iMarquam Nature Park, iPioneer Courthouse Square kunye nePowell Butte Nature Park. eyayiquka i-Wildwood Trail kunye neBridge.
Kanye njengoko Walker wanyusa malunga $500,000 ukusuka kuluntu Pioneer Courthouse Square ($ 15 ngelitye lokugalela), nonprofit Portland Parks Foundation wanyusa $2.2 yezigidi ukusuka malunga 900 iminikelo yabucala ukunceda inkxaso-mali bridge.The City of Portland, Portland Parks & Recreation kunye namanye amaqumrhu anikele intsalela malunga $4 million iindleko.
Umchweli uthe ukudibanisa amazwi kunye namazwi amaninzi kwiprojekthi kubonakalise umngeni, kodwa kufanelekile.
"Ndicinga ukuba awona mava abalulekileyo yintsebenziswano enkulu yabahlali, ukuzingca okukhulu, kunye nokuzibandakanya okukhulu - abantu bayayihlawula loo nto," utshilo uCarpenter.
UFinney wongeze ukuba yena neqela lakhe, kunye nabavelisi abanoxanduva lokuzisa uyilo ebomini, kwafuneka boyise imiceli mngeni emininzi kwimodeli ye-3D abayenzayo, ngenxa yabo bonke ubucukubhede bamalungu kunye nokufakwa.
“Sisebenzisana neenkcukhaca zethu ukuqinisekisa ukuba yonke imifuziselo iyahambelana kuba kwakhona, akukho ndawo yempazamo kuninzi lwala malungu ngenxa yokuntsokotha kwejometri,” utshilo uFinney.” Ngokuqinisekileyo intsonkothe ​​ngakumbi kunenkoliso.” Iibhulorho ezininzi zithe tye, kwanazo zigobileyo zineegophe, kwaye imathiriyeli ilula ngokwentelekiso.
“Ngenxa yoko, kukho ukuntsonkotha okuninzi okuvelayo kule projekthi. Ngokuqinisekileyo ndingatsho ukuba intsonkothe ​​ngakumbi kune [iprojekthi] eqhelekileyo. Kuthatha umsebenzi omninzi ukuze wonke umntu afezekise le projekthi.”
Nangona kunjalo, ngokutsho kweMchweli, phakathi kwezinto eziphambili kubunzima bebhulorho, yintoni enika ibhulorho isiphumo sayo sisonke yidekhi egobileyo.Ingaba kuyingxaki ukwenza oku?Kakhulu, ewe.
“Ndicinga ukuba uyilo olulungileyo ludla ngokuqala ngokusebenziseka luze ludlulele kwenye into engaphaya,” utshilo uMchweli.” Yiloo nto kanye eyenzekayo kule bhulorho. Ndicinga ukuba eyona nto ibalulekileyo yidesika egobileyo. Kule meko, andiziva mnandi ngebhari yeelekese kuba yonke le ndlela iyajikajika kwaye iyagoba.
Ibhulorho yabahambi ngeenyawo kaBarbara Walker yenziwa ngaphandle kwendawo, yahlulahlulwe yangamacandelo amabini aphambili, yaza yathunyelwa ngeelori kwindawo ekuyo ngoku.Portland Parks Foundation
"Uyenza njani idesika egobileyo? Ewe, kuvela, ngokuqinisekileyo, i-truss ye-chord-three-chord isebenza kakuhle kwi-curve. Ufumana i-deepsable deep-to-span ratio. Ke, ungenza ntoni nge-truss ye-three-chord ukuyenza ibe ntle kwaye i-Beauty, kwaye ibhekiselele ehlathini ngendlela eyenza kubonakale ngathi ayinakukwazi ukuqhubela phambili ngandlela-thile ngokubhekiselele kuyo nayiphi na into? Okanye ukusuka kwizinto ezisebenzisekayo ukuya kwintelekelelo .Abanye abantu basenokwenza ngenye indlela, kodwa leyo yindlela kanye endisebenza ngayo.”
Umchweli ubonga kakhulu iqela labasebenzi be-KPFF ngokumnika inkuthazo ethile awayeyidinga ukuze enze iprojekthi yemibhobho engaphaya kwedekhi, eyanika ibhulorho imvakalelo ephilayo, evela ehlathini.
“Kumnandi ukuba nento onokuyinika esi sixeko kwaye uzingce ngayo, kodwa kumnandi ukujongana nomceli mngeni wobunjineli ococekileyo,” utshilo uFinney.
Ngokutsho kwePortland Parks Foundation, malunga nabahambi ngeenyawo abangama-80,000 baya kusebenzisa ibhulorho yabahambi ngeenyawo nyaka ngamnye, besindisa ingxaki yokuwela icandelo lendlela ebona malunga neenqwelo ezingama-20,000 ngosuku.
Namhlanje, ibhulorho iyaqhubeka nombono kaWalker wokudibanisa abahlali basePortland kunye neendwendwe kubuhle bendalo engqongileyo.
UWalker (ocatshulwe liZiko Lehlabathi Lamahlathi) wakha wathi: “Kufuneka sincede abantu basezidolophini bakwazi ukufikelela kwindalo.” Uchulumanco ngendalo lubangelwa kukuba ngaphandle.
