Momwe Mungadziwire Njira Yoyenera Yomangira Ntchito
Kusankha njira yoyenera yomangira ndi chimodzi mwa zisankho zofunika kwambiri kuti polojekiti ipambane. Njira zomangira sizimangotanthauza "momwe mungamangire," koma zimaphatikizapo njira zogwirira ntchito, ndondomeko ya ntchito, zida ndi kusankha antchito, kasamalidwe kabwino, komanso kuwongolera ndalama ndi nthawi. Kusankha njira yolakwika kungayambitse kuchedwa, kukwera mtengo, kuwonongeka kwa khalidwe, komanso zoopsa zachitetezo. Chifukwa chake, njira yokhazikika ikufunika kuti njira yosankhidwayo igwirizane ndi mawonekedwe a polojekitiyo komanso momwe malo ake alili.
1. Kumvetsetsa kukula ndi zolinga za polojekitiyi kuyambira pachiyambi.
Gawo loyamba ndikumvetsetsa zikalata zokonzekera ndi zosowa za mwini polojekiti. Unikani zojambula zogwirira ntchito, zofunikira zaukadaulo, miyezo yaubwino yomwe mukufuna, ndi nthawi yomaliza ntchitoyo. Nyumba zazitali, misewu, milatho, madoko, kapena mafakitale amafunika njira zosiyanasiyana. Mwachitsanzo, mapulojekiti omwe amafunika kugwira ntchito mosalekeza (monga chipatala kapena fakitale yogwira ntchito mosalekeza) adzafunika njira zochepetsera kusokonezeka, phokoso, ndi fumbi.
Kuphatikiza apo, onetsetsani kuti zolinga za polojekitiyi zafotokozedwa momveka bwino: kodi liwiro lofunika kwambiri (njira yofulumira), kugwiritsa ntchito bwino ndalama, kapangidwe kake kapamwamba, kapena kulimba kwa nyumbayo kwa nthawi yayitali? Njira yoyenera yomangira nthawi zambiri ndiyo mgwirizano wabwino pakati pa zinthu zofunika izi.
2. Chitani kafukufuku wa momwe malo ndi malo ogwirira ntchito zilili
Njira iliyonse iyenera "kuthana ndi" mavuto a m'munda. Chifukwa chake, chitani kafukufuku wa malo mwatsatanetsatane momwe mungathere, kuphatikizapo:
- Kufikira zida ndi zinthu: kukula kwa msewu, malo ozungulira magalimoto, malire a nthawi yogwirira ntchito, kuchuluka kwa mlatho wolowera.
– Malo ndi momwe nthaka ilili: kukwera, kuthekera kwa kugwa kwa nthaka, mphamvu ya nthaka yonyamula, ndi kuchuluka kwa madzi apansi panthaka.
- Mikhalidwe yozungulira: kuchulukana kwa nyumba, nyumba zomwe zilipo kale, zinthu zapakhomo zomwe zili pansi pa nthaka, kapena madera omwe ayenera kukhala akugwira ntchito.
- Nyengo ndi nyengo: mvula yambiri ingakhudze njira zogwirira ntchito, kuponyera ndi kayendetsedwe ka zinthu.
Mwachitsanzo, pamalo ocheperako pakati pa mzinda, njira zopangira zinthu zokonzedweratu zingakhale zabwino kwambiri chifukwa zimachepetsa kufunika kwa malo ogwirira ntchito ndi mafomu. Mosiyana ndi zimenezi, mapulojekiti omwe ali pamalo akuluakulu omwe ali ndi njira zosavuta zopezera zinthu angasankhe njira zachikhalidwe, zomwe zimakhala zosinthasintha komanso zosawononga ndalama zambiri.
3. Kusanthula kapangidwe ndi zovuta zaukadaulo
Njira yomangira iyenera kugwirizana ndi kapangidwe ka nyumba ndi kapangidwe kake. Mapangidwe ena ndi oyenera njira zina, mwachitsanzo:
- Kapangidwe kobwerezabwereza komanso kofanana: koyenera kugwiritsa ntchito njira zokonzedweratu kapena machitidwe amakono opangira mawonekedwe (mawonekedwe a tebulo, mawonekedwe okwera).
– Kutalika: kungafunike njira zapadera monga kutsegulira magirders, chowongolera cholinganiza bwino, kapena kugwiritsa ntchito ma cranes akuluakulu.
- Kapangidwe ka mawonekedwe apadera: kungakhale koyenera kugwiritsa ntchito njira yopangira zinthu pogwiritsa ntchito formwork yapadera kapena ukadaulo wa BIM kuti ziwoneke bwino.
Kuchuluka kwa kulolera kwa miyeso kumachitanso gawo. Ngati pulojekiti ikufuna kulondola kwambiri, njira zowongolera kupanga (monga kupanga zinthu zokonzedwa kale kapena kupanga zitsulo) nthawi zambiri zimapereka kusinthasintha kwabwino kuposa ntchito yamanja m'munda.
4. Ganizirani nthawi yogwiritsira ntchito ndi njira yokonzekera nthawi.
Kusankha njira kumakhudzana kwambiri ndi nthawi ya polojekitiyi. Yerekezerani njira zina mwa kutsanzira ndondomeko pogwiritsa ntchito mapulani a netiweki (CPM), ndondomeko ya nthawi, kapena njira yolinganiza ntchito zobwerezabwereza. Unikani ngati njira inayake ingafulumizitse ntchito zofunika, mwachitsanzo:
- Sankhani zokonzedweratu kuti mufulumizitse kapangidwe ka superstructure.
- Kugwiritsa ntchito pompu yosakaniza bwino ndi simenti kuti ipange mwachangu.
- Gwiritsani ntchito ma shift a ntchito kapena njira zogwirira ntchito nthawi imodzi ngati malo ozungulira alola.
Komabe, liwiro liyenera kukhala loyenera: njira zachangu nthawi zambiri zimafuna mgwirizano wolimba wa zinthu, antchito aluso, komanso kuwongolera bwino khalidwe. Ngati njira zoperekera zinthu sizinakonzedwe, njira zachangu zitha kubweretsa kuchedwa.
5. Werengani ndalama zonse zomwe zimagwiritsidwa ntchito, osati ndalama zongogwiritsidwa ntchito mwachindunji.
Cholakwika chofala kwambiri ndi kuyerekeza njira zokha potengera ndalama zogulira zinthu kapena ntchito. Komabe, chofunika kwambiri ndi mtengo wonse wa polojekiti, kuphatikizapo:
- Ndalama zambiri zogulira zida, kusonkhanitsa/kuchotsa zida.
- Ndalama zobwereka makina a crane, scaffolding, kapena formwork system.
- Ndalama zomwe zimagwiritsidwa ntchito nthawi (ndalama zogwirira ntchito, lendi ya malo, kasamalidwe).
- Ndalama zolipirira zoopsa: kukonzanso ntchito, kuwonongeka, zopempha, ndi ndalama zomwe zingalipiridwe mochedwa.
- Zotsatira zachilengedwe ndi chikhalidwe cha anthu zomwe zimayambitsa ndalama zina (monga fumbi ndi kuwongolera phokoso).
Njira yomwe imawoneka yokwera mtengo poyamba ingakhale yotsika mtengo kwambiri ngati imachepetsa nthawi ya polojekiti ndikuchepetsa chiopsezo chokonzanso. Chifukwa chake, gwiritsani ntchito njira yowunikira phindu kapena kusanthula mtengo ndi phindu kuti musankhe zomwe mungasankhe.
6. Unikani kupezeka kwa zinthu: anthu, zida, ndi zipangizo
Njira yabwino kwambiri yolembedwa papepala ingalephereke ngati zinthu sizikupezeka. Chongani:
- Kupezeka kwa ogwira ntchito aluso: ogwira ntchito zomangira, olumikiza zitsulo ovomerezeka, oyendetsa ma crane, okonza ma rigger, ofufuza malo.
- Kupezeka kwa zida: mphamvu ya crane, zida zoikira milu, malo osungiramo zinthu, zida zoyesera zabwino.
- Kupezeka kwa zinthu: kupezeka kwa simenti, aggregate, chitsulo, zinthu zina zomalizidwira kale, kapena zinthu zina zomalizirira.
Ngati polojekitiyi ili kutali ndi malo operekera zinthu, njira zomwe zimafuna kupereka zinthu nthawi yomweyo zingakhale zoopsa. Muzochitika zotere, njira zomwe zimalekerera kusinthasintha kwa zinthu zomwe zimaloledwa kusungidwa zingakhale njira yotetezeka.
7. Phatikizanipo mbali za chitetezo kuntchito (K3) ngati chinthu chachikulu
Njira zomangira ziyenera kukhala patsogolo pa chitetezo. Unikani zoopsa zomwe zingachitike pa njira iliyonse yosiyana, monga kugwira ntchito pamalo okwera, kunyamula katundu wolemera, kufukula mozama, kapena kugwira ntchito pafupi ndi magalimoto a anthu ambiri. Njira zochepetsera zoopsa nthawi zambiri zimakondedwa.
Mwachitsanzo, kugwiritsa ntchito zinthu zokonzedwa kale kungachepetse ntchito yokonza ndi yolimbitsa pamalo okwera, koma kumawonjezera chiopsezo cha ntchito zonyamula. Izi zikutanthauza kuti njira iyi imakhalabe yotetezeka ngati ikuthandizidwa ndi njira zonyamulira, kuyang'anira zida, ndi antchito aluso.
8. Ganizirani za kuwongolera khalidwe ndi ubwino
Njira yosankhidwayo iyenera kukhala yokwanira kukwaniritsa miyezo ya khalidwe la polojekitiyi. Mfundo zofunika kuziganizira ndi izi:
- Kuthekera kwa njira iyi kusunga kukhazikika kwa konkriti (kutsika, kuuma, kutentha).
- Kulamulira kulekerera kwa miyeso ndi kulinganiza.
- Kusavuta kuyang'anira ndi kuyesa (NDT ya ma weld, kuyesa katundu, kuboola pakati).
- Zolakwika zomwe zingachitike ndi kukonzanso.
Pa ntchito zomwe zimafuna zinthu zapamwamba kwambiri—monga pansi m'mafakitale zomwe zimafuna kusalala pang'ono—njira zopangira, kumaliza, ndi kuyeretsa ziyenera kusankhidwa mosamala, kuphatikizapo kusankha zida monga laser screed kapena floor hardener ngati pakufunika.
9. Onetsetsani kuti malamulo ndi zilolezo zikutsatira malamulo
Njira zomangira nthawi zambiri zimakhudzidwa ndi malamulo am'deralo, monga malamulo oletsa phokoso, maola ogwirira ntchito, kasamalidwe ka magalimoto, ndi maudindo oyang'anira zinyalala. Pa mapulojekiti ena, zilolezo za pamsewu zogwiritsira ntchito makina oyendera kapena kunyamula zinthu zazikulu kwambiri ndizomwe zimapangitsa kuti ntchitoyi ichitike. Kuphwanya malamulowa kungayambitse kuyimitsidwa kwa ntchito kapena zilango, zomwe pamapeto pake zingawononge polojekitiyi.
10. Yerekezerani njira zingapo ndipo sankhani imodzi "yoyenera" bwino.
Mukafufuza zinthu zonse zomwe zili pamwambapa, pangani njira zingapo zosinthira ndikuziyerekeza pogwiritsa ntchito matrix ya zisankho. Zoyezera kulemera monga nthawi, mtengo wonse, OHS, mtundu, chiopsezo, ndi momwe zinthu zilili. Njira yabwino kwambiri ndi yomwe ili ndi zigoli zapamwamba kwambiri kutengera zomwe polojekiti ikufuna kuchita.
Gawo lomaliza, chitani mayeso oti muwone ngati zingatheke ndi:
- Njira yolembedwa yogwiritsira ntchito (mawu a njira).
- Kuyerekeza kwa ndondomeko ya ntchito (ndondomeko yomanga).
- Dongosolo la zida ndi anthu ogwira ntchito.
- Ndondomeko yaubwino (QA/QC) ndi ndondomeko ya K3.
- Dongosolo la kayendetsedwe ka zinthu ndi kapangidwe ka malo ogwirira ntchito (kapangidwe ka malo).
Kutseka
Kudziwa njira yoyenera yomangira pulojekiti si chisankho chadzidzidzi, koma njira yowunikira yomwe imaganizira kapangidwe kake, momwe malo alili, nthawi, ndalama zonse, zinthu, thanzi ndi chitetezo pantchito (K3), khalidwe, ndi malamulo. Njira yoyenera idzachepetsa ntchito, kuchepetsa zoopsa, ndikuwonetsetsa kuti zotsatira zake zikugwirizana ndi zolinga. Ndi njira yokhazikika—kuchokera ku maphunziro a pulojekiti ndi kafukufuku wa malo mpaka kusanthula kwina ndi kupanga mawu a njira—gulu la pulojekiti likhoza kusankha njira yoyenera kwambiri ndikutsogolera pulojekitiyo kuti ipambane.
Ngati mukufuna, nditha kusintha nkhaniyi kuti igwirizane ndi mtundu wa polojekiti inayake (monga nyumba zazitali, msewu, mlatho, kapena kukonzanso), yokhala ndi zitsanzo za njira ndi maphunziro afupiafupi.
