BIM在項(xiàng)目進(jìn)度管理上的應(yīng)用212012/4/263?

為何項(xiàng)目計(jì)劃與進(jìn)度管理很重要????

試回答:?

如果一切情況順利,項(xiàng)目何時(shí)完工??

哪些工作是最重要的??

如果必要的話,哪些工作延遲不會影響到項(xiàng)目總體進(jìn)度??

每個(gè)工作應(yīng)該何時(shí)開始和結(jié)束?422012/4/26?

誰做項(xiàng)目計(jì)劃與進(jìn)度管理??

項(xiàng)目經(jīng)理通常負(fù)責(zé)進(jìn)度的安排和協(xié)調(diào)工作??

分包商則是做自己工作細(xì)部的進(jìn)度規(guī)劃5632012/4/26?

做出工作分解結(jié)構(gòu)(WorkBreakdownStructure)和產(chǎn)生工作清單?

預(yù)估每項(xiàng)工作所需花的時(shí)間和費(fèi)用?

優(yōu)點(diǎn):?

容易了解?

跟工人之間容易溝通?

缺點(diǎn):?

無法有效的顯示一個(gè)工作延遲對項(xiàng)目完成時(shí)間的影響?

當(dāng)工作數(shù)量眾多,很難了解工作之間的相互邏輯關(guān)系1892012/4/26?

有可能將各工作依照最早開始或最晚開始邏輯排程?

最早開始排程:在不影響各工作間的邏輯順序下,將每個(gè)工作盡早開始?

最晚開始排程:在不影響各工作間的邏輯順序且不影響項(xiàng)目完工的情況下,將每個(gè)工作盡量晚開始19?

步驟:?

確定各項(xiàng)工作?

將各項(xiàng)工作排序?

對每項(xiàng)工作,要決定:?

那些工作要在這項(xiàng)工作之前完成??

哪些工作必須等這項(xiàng)工作完成后才可以開始??

哪些工作可以同時(shí)進(jìn)行?25?
