事前質量控制要點

1.1 熟(shu)悉(xi)施工圖紙

建(jian)造一個合格的(de)運動場地(di)，是一項非常(chang)專業化的(de)體育(yu)工(gong)藝(yi)，專業設(she)(she)計不同于通(tong)常(chang)民用建(jian)筑，它(ta)應該根據(ju)國際田(tian)聯《田(tian)徑設(she)(she)施手冊》和中(zhong)國田(tian)徑協(xie)會《田(tian)徑競賽規則》最(zui)新規范、標準(zhun)進行(xing)設(she)(she)計施工(gong)。監理人員應重點(dian)審查圖紙(zhi)中(zhong)的(de)以下問題：

1)設計(ji)說明(ming)是(shi)否(fou)(fou)完善。主要審查(cha)(cha)說明(ming)中是(shi)否(fou)(fou)符(fu)合(he)國際(ji)田徑(jing)聯合(he)會公布的(de)(de)田徑(jing)場地(di)(di)設施(shi)手冊中有關場地(di)(di)的(de)(de)規定。2)設計(ji)圖紙是(shi)否(fou)(fou)完整(zheng)(zheng)。除審查(cha)(cha)圖紙做法是(shi)否(fou)(fou)完整(zheng)(zheng)外，還應重點(dian)審查(cha)(cha)各(ge)種邊界(jie)定位(wei)及詳細定位(wei)是(shi)否(fou)(fou)標注明(ming)確。3)是(shi)否(fou)(fou)有地(di)(di)質資料(liao)。

1.2 設計交(jiao)底(di)及圖紙會(hui)審

在(zai)硅PU塑膠場地施工(gong)(gong)(gong)(gong)時，應(ying)本(ben)著“事前控制(zhi)、主動控制(zhi)”的(de)(de)(de)原(yuan)則，結合以(yi)(yi)往(wang)的(de)(de)(de)經(jing)驗(yan)教訓(xun)，針(zhen)對(dui)施工(gong)(gong)(gong)(gong)時有可能出現的(de)(de)(de)問題，要求(qiu)承(cheng)包單位對(dui)報送(song)重點部位、關鍵(jian)程(cheng)序的(de)(de)(de)施工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝和確(que)保(bao)工(gong)(gong)(gong)(gong)程(cheng)質量的(de)(de)(de)措施進行研究(jiu)、比(bi)較、確(que)認(ren)后，形(xing)成統一的(de)(de)(de)方案，以(yi)(yi)工(gong)(gong)(gong)(gong)程(cheng)例會的(de)(de)(de)形(xing)式(shi)進行監(jian)理技術交(jiao)底，并(bing)以(yi)(yi)書(shu)面的(de)(de)(de)形(xing)式(shi)下發(fa)到施工(gong)(gong)(gong)(gong)單位，確(que)保(bao)施工(gong)(gong)(gong)(gong)時各工(gong)(gong)(gong)(gong)序的(de)(de)(de)順利進行。

1.3 熟悉現場情況(kuang)，及時做好技術變(bian)更(geng)建議

對于硅(gui)PU塑膠場(chang)地施(shi)工，應(ying)注意查看現場(chang)場(chang)地土質是否與地質資料相一致，如發現不相符(fu)，做法不妥或不符(fu)合場(chang)地建(jian)設(she)(she)(she)要(yao)求(qiu)，能比較好改進的應(ying)及時(shi)向業主(zhu)反映，并與設(she)(she)(she)計(ji)單位洽商確定，形成設(she)(she)(she)計(ji)文件，以便于依照執行及備案。
