Pa ntchito yomanga, kukhala ndi zipangizo zoyenera n’kofunika kwambiri kuti ntchitoyo igwire bwino ntchito. Zofukula zimakhala zofala pa malo omanga ndipo njanji zomwe amagwiritsa ntchito zimagwira ntchito yofunika kwambiri. Mzaka zaposachedwa,nyimbo za rabara excavatorzakhala zotchuka kwambiri chifukwa cha zabwino zawo zambiri kuposa nyimbo zachikhalidwe zachitsulo.

Ubwino umodzi waukulu wa njanji zofukula mphira ndikutha kuchepetsa kuwonongeka kwa nthaka. Njanji zachikale zimatha kuwononga kwambiri pansi, makamaka pamalo otetezeka monga udzu, phula kapena konkire. Komano, njanji za mphira zimagawa kulemera kwa chofufutira mofanana, kuchepetsa kukhudzidwa pansi ndi kuchepetsa chiopsezo cha kuwonongeka. Izi zimapangitsa kuti njanji za mphira zikhale zabwino kwambiri pantchito yomanga yomwe imafunikira kumangidwa pamalo osalimba kapena m'matauni komwe chitetezo chapansi chimakhala chofunikira kwambiri.

Kuwonjezera pa makhalidwe awo abwino,njira za excavatorperekani kuyenda bwino komanso kukhazikika. Zida za mphira zimagwira bwino pazigawo zosiyanasiyana, kuphatikiza dothi, miyala, ndi malo osagwirizana. Kukokera kowonjezereka kumeneku kumapangitsa chofufutira kuti chiziyenda bwino ngakhale pakakhala zovuta, ndipo pamapeto pake kumawonjezera zokolola ndikuchepetsa chiopsezo choterereka kapena kukakamira.

Kuonjezera apo, nyimbo za rabara zimayenda bwino komanso zopanda phokoso kusiyana ndi zitsulo zachitsulo. Kusinthasintha kwa njanji za rabala kumatengera kugwedezeka ndi kugwedezeka, kumachepetsa phokoso, komanso kumapereka malo ogwirira ntchito omasuka kwa ogwira ntchito ndi ogwira ntchito pafupi. Izi ndizopindulitsa makamaka pantchito zomanga m'malo okhalamo kapena m'malo osamva phokoso.

Ubwino wina waukulu wa njanji zofukula mphira ndi kusinthasintha kwawo. Iwo ali oyenerera ntchito zosiyanasiyana, kuchokera kumalo osungiramo malo ndi kugwetsa mpaka kumanga misewu ndi ntchito zothandizira. Kukhoza kwawo kutengera malo ndi malo osiyanasiyana kumawapangitsa kukhala chuma chamtengo wapatali kwa makontrakitala ndi makampani omanga omwe akufuna kukulitsa luso la ofukula awo pama projekiti osiyanasiyana.

Kuphatikiza apo, ma track a rabara nthawi zambiri amakhala ndi zofunikira zocheperako kuposa ma track achitsulo. Zimakhala zosagwira dzimbiri ndi dzimbiri, ndipo mapangidwe ake nthawi zambiri amakhala ndi zinthu zodziyeretsa zomwe zimathandiza kuti zinyalala zisamangidwe. Izi zimachepetsa nthawi yochepetsera ndi kukonza ndalama, potsirizira pake zimathandizira kuonjezera ntchito zogwirira ntchito komanso zotsika mtengo.

Mwachidule, kugwiritsa ntchitonyimbo za rabara za excavatorzabweretsa phindu lalikulu pantchito yomanga. Ubwenzi wawo wapansi, kuyenda bwino, kuchepa kwa phokoso, kusinthasintha komanso zofunikira zochepetsera zosamalira zimawapangitsa kukhala ndalama zopindulitsa kwa makontrakitala ndi makampani omanga. Pamene ntchito yomangamanga ikupitiriza kuika patsogolo kuti ikhale yokhazikika komanso yogwira ntchito bwino, kugwiritsa ntchito njanji za rabara kumakhala kofala kwambiri, zomwe zimathandiza kuti ntchito yomanga ikhale yotetezeka komanso yothandiza kwambiri.
