呼和浩特膜結(jie)構(gou)工程結(jie)算是(shi)(shi)整(zheng)(zheng)個(ge)工程項目(mu)造(zao)(zao)(zao)價(jia)(jia)控制的收尾階段，膜結(jie)構(gou)基(ji)礎工程造(zao)(zao)(zao)價(jia)(jia)因(yin)其在整(zheng)(zheng)個(ge)工程項目(mu)造(zao)(zao)(zao)價(jia)(jia)中所占比例(li)較小，而往往沒(mei)有引起(qi)造(zao)(zao)(zao)價(jia)(jia)人員的足(zu)夠注意。實際上，承包商常(chang)(chang)常(chang)(chang)是(shi)(shi)從這一分部分項工程中獲取額(e)外(wai)的利(li)潤；同時，膜結(jie)構(gou)基(ji)礎工程造(zao)(zao)(zao)價(jia)(jia)因(yin)其特殊(shu)性，造(zao)(zao)(zao)價(jia)(jia)控制有一定(ding)的難度，引起(qi)的糾紛也較多。

那么(me),都哪些元素還(huan)影響膜結構工程(cheng)的造(zao)價呢?

1．由(you)于(yu)膜結(jie)(jie)構(gou)建設工(gong)(gong)(gong)程一般工(gong)(gong)(gong)期較短，而基(ji)礎工(gong)(gong)(gong)程在施(shi)工(gong)(gong)(gong)初期階段現場(chang)(chang)施(shi)工(gong)(gong)(gong)條件比(bi)較復雜(za)，膜結(jie)(jie)構(gou)工(gong)(gong)(gong)程各方管理又不(bu)(bu)健全，往往給結(jie)(jie)算造價(jia)帶來(lai)很大差異。在實際(ji)(ji)結(jie)(jie)算工(gong)(gong)(gong)作中經(jing)(jing)常會出現由(you)于(yu)現場(chang)(chang)基(ji)礎軋鋼筋、調(diao)配(pei)等(deng)方面(mian)管理不(bu)(bu)善造成結(jie)(jie)算造價(jia)的大幅度(du)上漲，這種由(you)于(yu)對現場(chang)(chang)情(qing)況預計不(bu)(bu)足(zu)、管理不(bu)(bu)善而造成的二(er)次(ci)調(diao)整、三次(ci)調(diao)整的情(qing)況在實際(ji)(ji)工(gong)(gong)(gong)程中經(jing)(jing)常發生，使(shi)膜結(jie)(jie)構(gou)基(ji)礎工(gong)(gong)(gong)程造價(jia)很難(nan)控制。

2．膜結構基(ji)礎工(gong)程(cheng)屬于(yu)隱(yin)蔽工(gong)程(cheng)，如果(guo)沒(mei)有(you)完整(zheng)(zheng)(zheng)的(de)(de)(de)(de)隱(yin)蔽工(gong)程(cheng)記錄，對(dui)設計變(bian)更(geng)、工(gong)程(cheng)聯(lian)系單等未辦理(li)相應的(de)(de)(de)(de)簽證或以(yi)(yi)書(shu)面形(xing)式加以(yi)(yi)確認，必將影響(xiang)結算階段的(de)(de)(de)(de)計價工(gong)作。工(gong)程(cheng)管(guan)理(li)人(ren)(ren)員(yuan)(yuan)的(de)(de)(de)(de)流動(dong)性也較大(da)，有(you)時甚至會出現工(gong)程(cheng)項目(mu)結束，整(zheng)(zheng)(zheng)個(ge)甲(jia)方的(de)(de)(de)(de)現場管(guan)理(li)人(ren)(ren)員(yuan)(yuan)全部(bu)流失的(de)(de)(de)(de)情(qing)況(kuang)。如果(guo)沒(mei)有(you)完整(zheng)(zheng)(zheng)的(de)(de)(de)(de)隱(yin)蔽工(gong)程(cheng)記錄，沒(mei)有(you)對(dui)設計變(bian)更(geng)、工(gong)程(cheng)聯(lian)系單的(de)(de)(de)(de)工(gong)作內容是否已(yi)(yi)按要(yao)求施工(gong)進(jin)行確認，就(jiu)會出現工(gong)作量無(wu)法認可的(de)(de)(de)(de)情(qing)況(kuang)，使得結算工(gong)作非常被動(dong)。因隱(yin)蔽工(gong)程(cheng)記錄對(dui)此無(wu)記載，其他竣工(gong)資料也沒(mei)有(you)反應，偏偏整(zheng)(zheng)(zheng)個(ge)項目(mu)的(de)(de)(de)(de)工(gong)程(cheng)管(guan)理(li)人(ren)(ren)員(yuan)(yuan)在項目(mu)結束后都已(yi)(yi)離(li)職(zhi)，故此部(bu)分(fen)基(ji)礎工(gong)程(cheng)的(de)(de)(de)(de)結算爭議(yi)相當大(da)，只能是折中(zhong)處理(li)，沒(mei)有(you)做到客觀、真實的(de)(de)(de)(de)完成計價工(gong)作。

3．由于(yu)膜結(jie)構工(gong)(gong)(gong)(gong)程施(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序、方(fang)法、工(gong)(gong)(gong)(gong)期、季節性施(shi)工(gong)(gong)(gong)(gong)等原因(yin)給造價(jia)帶來的(de)(de)(de)差異。實際工(gong)(gong)(gong)(gong)作中施(shi)工(gong)(gong)(gong)(gong)單位(wei)編制(zhi)的(de)(de)(de)施(shi)工(gong)(gong)(gong)(gong)方(fang)案是大的(de)(de)(de)膜結(jie)構項目基坑(keng)采(cai)用機械(xie)破(po)除地(di)(di)面(mian)，根(gen)據有關施(shi)工(gong)(gong)(gong)(gong)規范(fan)的(de)(de)(de)規定，基坑(keng)機械(xie)挖(wa)土(tu)(tu)(tu)(tu)時，為(wei)(wei)防止超挖(wa)及對(dui)基底原土(tu)(tu)(tu)(tu)的(de)(de)(de)擾動，只能開挖(wa)至基底以(yi)上(shang)30cm，用人(ren)工(gong)(gong)(gong)(gong)挖(wa)土(tu)(tu)(tu)(tu)完成剩余的(de)(de)(de)基礎破(po)除地(di)(di)面(mian)工(gong)(gong)(gong)(gong)作。因(yin)此(ci)，實際施(shi)工(gong)(gong)(gong)(gong)中，施(shi)工(gong)(gong)(gong)(gong)單位(wei)在已經平整好的(de)(de)(de)場(chang)地(di)(di)進行基坑(keng)機械(xie)挖(wa)土(tu)(tu)(tu)(tu)，挖(wa)到離設計基底標高20-30cm處(chu)改用人(ren)工(gong)(gong)(gong)(gong)挖(wa)土(tu)(tu)(tu)(tu)。因(yin)此(ci)甲(jia)方(fang)計價(jia)人(ren)員將這20—30cm的(de)(de)(de)人(ren)工(gong)(gong)(gong)(gong)挖(wa)土(tu)(tu)(tu)(tu)套場(chang)地(di)(di)平整項目，而施(shi)工(gong)(gong)(gong)(gong)單位(wei)計價(jia)人(ren)員則認(ren)為(wei)(wei)應套機械(xie)挖(wa)土(tu)(tu)(tu)(tu)。由于(yu)定額的(de)(de)(de)計價(jia)規則對(dui)此(ci)無(wu)明確規定，結(jie)果出現爭議。

4．由(you)于基礎(chu)工(gong)程(cheng)(cheng)所處的(de)(de)(de)地(di)(di)理條件復雜(za)，地(di)(di)質(zhi)勘測(ce)取樣數量(liang)不(bu)(bu)足(zu)、可靠性不(bu)(bu)高(gao)和(he)圖形的(de)(de)(de)不(bu)(bu)規(gui)則給工(gong)程(cheng)(cheng)量(liang)的(de)(de)(de)計(ji)算帶來差(cha)異。基礎(chu)工(gong)程(cheng)(cheng)是項目開(kai)發初期的(de)(de)(de)第一(yi)步工(gong)作，往往由(you)于項目用地(di)(di)的(de)(de)(de)地(di)(di)理條件復雜(za)(例如山(shan)地(di)(di)、坡地(di)(di))、地(di)(di)址勘測(ce)取樣數量(liang)不(bu)(bu)足(zu)(取樣點間距過大(da)，不(bu)(bu)能準(zhun)確(que)(que)反映(ying)實(shi)際地(di)(di)質(zhi)地(di)(di)貌)等原因，影響了竣工(gong)圖紙的(de)(de)(de)準(zhun)確(que)(que)性，從而使得膜(mo)結構基礎(chu)工(gong)程(cheng)(cheng)的(de)(de)(de)工(gong)程(cheng)(cheng)量(liang)計(ji)算不(bu)(bu)夠(gou)準(zhun)確(que)(que)。
