Ubude bokulethwa kwepayipi lensimbi engagqwali bubizwa nangokuthi ubude obucelwe ngumsebenzisi noma ubude benkontileka.Kunemithetho eminingana yobude bokulethwa ekucacisweni:

A. Ubude obujwayelekile (obuye baziwe ngokuthi ubude obungaguquki): Noma yiliphi ipayipi lensimbi engagqwali ubude balo bungaphakathi kwesikali sobude besimiso futhi ngaphandle kwesicelo sobude obunqunyiwe libizwa ngokuthi ubude obuvamile.Isibonelo, imithetho yokucaciswa kwepayipi lesakhiwo: ipayipi lensimbi eligoqiwe elishisayo (eligxotshiwe, lanwetshwa) 3000mm~12000mm;ipayipi elibandayo elidonswe (eligoqiwe) lensimbi 2000mm ~ 10500mm.

B. Ubude bokusika-ubude: Ubude bokusika-ubude kufanele bube phakathi kwesikali sobude esijwayelekile, esicelwe kwinkontileka A incazelo yobude obungashintshi.Kodwa-ke, ekusebenzeni, akunakwenzeka ukuqinisekisa ukuthi ubude obunqunyiwe bunqunyiwe.Ngakho-ke, inani lephutha eliphozithivu elivunyelwe umthetho wobude obugxilile ekucacisweni.

C. Ubude bezinyawo eziningi: Ubude bezinyawo eziphindaphindiwe kufanele bube phakathi kwesikali sobude esivamile.Inkontileka kufanele ikhombise ubude bonyawo olulodwa kanye nokuphindaphinda kobude obuphelele (isibonelo, 3000mm×3, okuziphindwayo ezingu-3 zika-3000mm, kanti ubude obuphelele bungu-9000mm).Empeleni, ubude obuphelele kufanele bufakwe ngephutha elihle lika-20mm, kanye nemajini yokusika kufanele iyekwe ubude berula ngalinye.Ukuthatha ipayipi lesakhiwo njengesibonelo, umthetho uwukushiya imvume yokusika: ububanzi bangaphandle ≤159mm ngu-5 ~ 10mm;ububanzi obungaphandle>159mm bungu-10 ~ 15mm.

D. Ubude besikali: ubude besikali sepayipi lensimbi engagqwali bungaphakathi kwesikali sobude obujwayelekile, lapho umsebenzisi esicela Uma ubude besikali bunqunyiwe, buzokhonjiswa kwinkontileka.

Kuyabonakala ukuthi ubude besikali buxega kunezidingo zobude obungaguquki kanye nobude obuphindwe kabili, kodwa buqinile kakhulu kunobude obujwayelekile, okuzoletha nokwehla kwezinga lokukhiqiza lenkampani ekhiqizayo.Ngakho-ke, kunengqondo ukuthi inkampani yokukhiqiza inyuse intengo.Ukushintshashintsha kokukhuphuka kwentengo ngokuvamile kuba ngu-4% yenani lesisekelo.
