事前質量控制要點

1.1 熟悉施工圖紙

建造(zao)一個合格的運動場地，是一項非常專(zhuan)業(ye)化(hua)的體育工藝，專(zhuan)業(ye)設計(ji)不同(tong)于通常民用(yong)建筑，它應(ying)該根(gen)據(ju)國(guo)際田(tian)(tian)聯《田(tian)(tian)徑設施手冊》和(he)中國(guo)田(tian)(tian)徑協會《田(tian)(tian)徑競賽規(gui)則》最新規(gui)范、標準進行設計(ji)施工。監理人員(yuan)應(ying)重點審查圖紙中的以(yi)下問(wen)題：

1)設計(ji)說明是否(fou)(fou)完(wan)善。主要(yao)審查說明中是否(fou)(fou)符合國際田(tian)徑聯(lian)合會公布的田(tian)徑場地設施手冊中有(you)關場地的規(gui)定(ding)。2)設計(ji)圖紙是否(fou)(fou)完(wan)整(zheng)。除審查圖紙做法是否(fou)(fou)完(wan)整(zheng)外，還(huan)應重點審查各種(zhong)邊界(jie)定(ding)位(wei)及詳(xiang)細定(ding)位(wei)是否(fou)(fou)標注(zhu)明確。3)是否(fou)(fou)有(you)地質資料。

1.2 設計交(jiao)底及圖紙會審

在硅PU塑(su)膠場地施工(gong)(gong)(gong)時(shi)(shi)，應本著“事前控(kong)制、主動控(kong)制”的(de)(de)原則(ze)，結合以往的(de)(de)經(jing)驗教訓，針對(dui)施工(gong)(gong)(gong)時(shi)(shi)有可能出現(xian)的(de)(de)問題，要(yao)求承包單(dan)位(wei)對(dui)報送重點(dian)部位(wei)、關鍵程序的(de)(de)施工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)和確(que)保工(gong)(gong)(gong)程質量的(de)(de)措(cuo)施進(jin)行(xing)研(yan)究、比較、確(que)認后(hou)，形成統一的(de)(de)方案，以工(gong)(gong)(gong)程例會的(de)(de)形式進(jin)行(xing)監理技術交底(di)，并以書面(mian)的(de)(de)形式下發到施工(gong)(gong)(gong)單(dan)位(wei)，確(que)保施工(gong)(gong)(gong)時(shi)(shi)各工(gong)(gong)(gong)序的(de)(de)順利進(jin)行(xing)。

1.3 熟悉現場情況，及時做好技(ji)術變更建議

對于硅PU塑(su)膠(jiao)場(chang)地(di)施工，應(ying)注意查(cha)看現場(chang)場(chang)地(di)土(tu)質是否與地(di)質資料相一致(zhi)，如發現不相符(fu)，做法不妥(tuo)或(huo)不符(fu)合場(chang)地(di)建設要(yao)求，能比較好改進的應(ying)及(ji)時向業主反映(ying)，并與設計單位洽商確定，形成設計文件，以便于依照執(zhi)行及(ji)備案。
