Pulogalamu yapamwamba yachitsulo pepala mulumachitidwe tsopano akuthandiza kumanga mlatho wofulumira wa njanji yothamanga kwambiri pamapulojekiti akuluakulu angapo ku North America, Latin America ndi Asia. Malipoti aumisiri akuwonetsa kuti njira yolimbikitsira yotengera magiredi achitsulo champhamvu kwambiri, njira zokhazikitsira modular komanso chitetezo chambiri cha dzimbiri zimathandizira kuchepetsa nthawi yomanga maziko, ndikuwonjezera kukhazikika kwadongosolo kwanthawi yayitali.
Oyang'anira projekiti panjira ya njanji yothamanga kwambiri ku US West Coast anena kuti zaluso kwambiri.pepala mulusystem imafulumizitsa ntchito yomanga ma cofferdam, imachepetsa kufunika kwa zida zolemetsa, ndikuwonjezera chitetezo m'nthaka yodzaza ndi madzi komanso yofewa. Tekinoloje iyi imathandizira kuyika mozama komanso kukweza kokulirapo komwe kumapangitsa kuti ikhale yoyenera pobowola mlatho ndikupumira m'malo ovuta.
Ku Mexico ndi Chile, komwe njira zingapo zatsopano za njanji zikuyenda, makontrakitala akuwunikira zatsopanozimulemba mulu wa pepalayankho limapereka kusungirako pansi kotsika mtengo, kumathandizira kukumba mwachangu, komanso kumapereka njira yochepetsera zachilengedwe ku makoma achikhalidwe olimba a konkriti. Kugwiritsiridwa ntchito kwake kumachepetsanso zinyalala zakuthupi ndi kutulutsa mpweya wonse wa polojekiti.
Kupititsa patsogolo kwakukulu kumabwera chifukwa chogwiritsa ntchito zitsulo zamphamvu kwambiri zomwe zimagwirizana ndi miyezo ya ASTM/AASHTO, kulolamumapanga mulu wachitsulokupsinjika ndi zovuta zazikulu zomwe zikuyembekezeredwa mu njanji yothamanga kwambiri. Zovala zowoneka bwino zosagwirizana ndi dzimbiri zimawonjezeranso moyo wautumiki wopatsa kukhazikika kwanthawi yayitali kwa milatho yanjanji yopangidwira zaka 80-100.
Akuluakulu ochokera ku maunduna osiyanasiyana a zamayendedwe ati njira yoyendetsera bwino njanjiyi ikhala yofunika kwambiri m'tsogolomu pakukulitsa njanji zothamanga kwambiri. Pamene ndalama zapadziko lonse lapansi zimayang'ana kwambiri mayendedwe ofulumira a moyo komanso njira yobiriwira yomangira, njira yopangira zitsulo zachitsulo idzakhala muyezo wopangira milatho yatsopano yanjanji.
Pamene mayiko akuthamangira kumanga masitima apamtunda othamanga a m'badwo wotsatira, luso lamakono lazitsulo lazitsulo lidzasintha ntchito yomanga milatho ikuluikulu, kupititsa patsogolo ntchito yopereka ntchito ndi kupereka milatho yolimba ndi zothetsera zokhazikika kwa mibadwo ya omanga zomangamanga.
