Lipotso tse botswang hangata

Contingency e utlwahalang bakeng sa diporojeke tsa kaho Afrika Borwa ke efe?

Bakeng sa diporojeke tsa kaho Afrika Borwa, kenya:

10-15% contingency bakeng sa tse sa tsejweng le dikotsi tse akaretsang
5-10% e eketsehileng bakeng sa inflation ya ditheko tsa thepa (haholo nakong ya ho fetoha ha mmaraka)
R10,000-R30,000 ka kgwedi bakeng sa ditjeho tsa load shedding (mafura a generator, tahlehelo ya tlhahiso)
3-5% bakeng sa mathata a moralo le variation tse lebellwang

Contingency yohle hangata e pakeng tsa 15-25% ho latela boima ba porojeke le maemo a mmaraka.

Na nka busetswa ditjeho tse bakwang ke diphoso tsa moralo?

Ho itshetlehile ka konteraka ya hao. Dikonteraka tse ngata tse tlwaelehileng (JBCC, NEC, GCC) di dumella hore o koptje ditjeho bakeng sa diphoso tsa moralo haeba e le boikarabelo ba moreki kapa moqapi. Leha ho le jwalo, o tshwanetse ho:

Fumana diphoso kapele mme o tsebise moreki
Ngola phoso le kameho ya yona ditjehong

Fumana tumello ya moreki pele o tsoela pele

Haeba diphoso tsa moralo e le boikarabelo ba hao (mohlala, o ne o tshwanetse ho di bona nakong ya tender), o ka se kgone ho busetswa ditjeho.

Ke sebetsana jwang le keketseho ya ditheko tsa thepa kamora tender?

Keketseho ya ditheko tsa thepa kamora tender ke kotsi e kgolo. Dikgetho di kenyelletsa:

Price escalation clauses - Kenya dikhaolo tse dumellang hore ditheko di fetolwe ha ditheko tsa thepa di nyoloha
Ho oda kapele - Oda thepa ya bohlokwa kapele ho notlela ditheko
Fixed-price agreements - Buisana ka ditumellano tsa phepelo tse nang le ditheko tse tsitsitseng
Variation orders - Ha ditheko di nyoloha ka lebaka la tieho kapa diphetoho tsa moreki, kopa ka variation

Haeba ditheko tsa thepa di nyoloha ka lebaka la maemo a mmaraka mme o se na escalation clauses, o ka qetella o jara ditjeho - ke kahoo ho kenyelletsa inflation ya ditheko tsa thepa ka estimate ho leng bohlokwa.

Ke tshwanetse ho etsang haeba porojeke e se e feta budget?

Haeba porojeke e se e feta budget:

Hlahloba boemo - E feta budget ka bokae? E bakilwe ke eng? Na ditjeho di ka busetswa?
Kgetha ditjeho tse ka busetswang - Ke ditjeho dife tse ka kopuwang ka variation orders?
Ngola tsohle - Boloka lirekoto tse qaqileng tsa mabaka le ditjeho
Hlahisa variation orders - Romela variation orders bakeng sa ditjeho tsohle tse ka busetswang
Laola ditjeho tse ding - Nka mehato ho thibela overrun e nngwe
Forecast ya ditjeho tsa ho qetela - Bolela ditjeho tsa ho qetela mme o rere ka nepo
Buisana le moreki - Eba pepeneneng ka boemo le leano la tokiso

Nka thibela jwang overrun e bakwang ke scope creep?

Thibela overrun ya scope creep ka ho:

Eba le tshebetso e hlakileng ya variation
Ngola diphetoho tsohle tsa scope ka variation orders tse nepahetseng
Fumana tumello ya moreki le ditheko pele o tsoela pele
Sebedisa software ya project management ho latela variation
Kenya buffer ka estimate bakeng sa variation tse lebellwang
Ho re “tjhe” diphetohong tse se nang variation orders tse nepahetseng

Phapang pakeng tsa contingency le profit ke efe?

Contingency le profit di sebeletsa merero e fapaneng:

Contingency - Buffer bakeng sa tse sa tsejweng le dikotsi (10-15% ya boleng ba porojeke)
Profit - Margin ya hao bakeng sa ho nka porojeke (hangata 10-20% ya boleng ba porojeke)
