事前質量控制要點

1.1 熟悉施工(gong)圖紙(zhi)

建造一(yi)個合格(ge)的(de)(de)運動(dong)場地，是一(yi)項非常專業化的(de)(de)體育工(gong)藝，專業設(she)(she)計不同于通常民(min)用建筑，它應該根(gen)據國(guo)際田(tian)聯《田(tian)徑(jing)設(she)(she)施手(shou)冊》和中國(guo)田(tian)徑(jing)協會《田(tian)徑(jing)競賽規則(ze)》最新規范、標準進(jin)行(xing)設(she)(she)計施工(gong)。監理人員應重點審(shen)查圖紙(zhi)中的(de)(de)以下問題：

1)設計(ji)說明是(shi)否完善。主要審(shen)查說明中是(shi)否符(fu)合(he)國際田徑聯合(he)會公(gong)布的(de)田徑場地設施手冊中有(you)關場地的(de)規定。2)設計(ji)圖紙是(shi)否完整。除審(shen)查圖紙做法(fa)是(shi)否完整外，還(huan)應重點審(shen)查各種邊界定位及詳細定位是(shi)否標注明確。3)是(shi)否有(you)地質資料。

1.2 設(she)計交底及圖紙會審

在(zai)硅PU塑(su)膠場地施工時，應本著“事前控(kong)制(zhi)、主動控(kong)制(zhi)”的(de)(de)(de)原則，結合以(yi)往的(de)(de)(de)經驗教(jiao)訓，針對施工時有可能(neng)出現的(de)(de)(de)問題(ti)，要(yao)求承包單(dan)位對報送重點部位、關鍵程(cheng)(cheng)序的(de)(de)(de)施工工藝和確保工程(cheng)(cheng)質量的(de)(de)(de)措施進(jin)行(xing)研(yan)究(jiu)、比較、確認(ren)后，形成(cheng)統(tong)一(yi)的(de)(de)(de)方案，以(yi)工程(cheng)(cheng)例會的(de)(de)(de)形式進(jin)行(xing)監理技術交底，并以(yi)書面的(de)(de)(de)形式下發到施工單(dan)位，確保施工時各工序的(de)(de)(de)順利進(jin)行(xing)。

1.3 熟(shu)悉現場情況，及時做好技術變更建議

對于硅PU塑膠場(chang)地施工，應(ying)注意(yi)查看現場(chang)場(chang)地土質是否與地質資料相一致(zhi)，如發現不相符(fu)，做法不妥或不符(fu)合(he)場(chang)地建設(she)要求，能比(bi)較好改進(jin)的應(ying)及時向(xiang)業主反(fan)映，并(bing)與設(she)計(ji)單位洽商確定，形成(cheng)設(she)計(ji)文件，以便于依照執行及備案。
