Ukuhanjiswa okusemgangathweni ubude beumbhobho wentsimbi yekhabhoni, eyaziwa ngokuba ziimfuno zomsebenzisi ubude okanye ubude bekhontrakthi, kukho izibonelelo ezine kwimigangatho ekhoyo:

A, Ubude obuqhelekileyo (okwaziwa ngokuba ngobude obungakhethi): nabuphi na ubude phakathi kobude bomgangatho ofunekayo kwaye akukho mfuneko yobude obumiselweyo budla ngokubizwa ngokuba bubude obuqhelekileyo.

B, Sika ubude: ubude bokusika kufuneka bube phakathi kobude obuqhelekileyo, obufunekayo kwikhontrakthi ubude obumiselweyo.Kodwa owona msebenzi unqunywe ngokuqinisekileyo kwaye akunakwenzeka, ngoko umgangatho uchaza ubude bobude benxanxathela evumelekileyo.Imveliso ehlileyo ubude kunobude bobude betyhubhu yombhobho idla ngokuba sisivuno somda omkhulu, abavelisi abacetywayo bonyuso lwexabiso lokukhwela lufanelekile.Amashishini eMarkups awahambelani, ngokuqhelekileyo asekelwe kwisiseko sokunyuka kwexabiso malunga ne-10%.

C, Ubude obuphindwe kabini: ngokwemfuno yomyalelo, ubude yinani elipheleleyo eliphindaphindwayo kwaye libhekiselwa kubo njengobude obuphindiweyo.Ubude obuphindwe kabini kufuneka bube phakathi koluhlu lobude obuqhelekileyo, ikhontrakthi kufuneka ichaze ubude obuphindwe kabini kunye nokwakhiwa kobude obuphindwayo bubonke.Ukwenza, ubude bubonke kufuneka busekelwe ekutenxeni okuvumelekileyo okuvumelekileyo nge-20mm, kunye nobude obuphindwe kabini bomda omnye wokusika kufuneka uhlale.Ukuba ukutenxa okusemgangathweni akukho bude obuphindwe kabini kunye neemfuno zokusika umda, kufuneka kuxoxwe ngawo omabini amaqela kwaye kuchazwe kwikhontrakthi.Ubude bexesha elide lokulinganisa ubude obufanayo nemveliso iya kuzisa ukwehla okubonakalayo kwisivuno, ngoko ke abavelisi abacetywayo bonyuso bufanelekile, kunye nesantya sokunyuka kunye nobude bezinga lokunyuka ngokubonakalayo ubude obufanayo.

D, Ubude boMda: ubude boluhlu bungaphakathi koluhlu lobude obuqhelekileyo, xa umsebenzisi ecela uluhlu olusisigxina apho ubude bexesha, kufuneka buchazwe kwikhontrakthi.
