1)設計(ji)說(shuo)明是(shi)(shi)否(fou)完(wan)善。主要審查(cha)說(shuo)明中是(shi)(shi)否(fou)符合國際田徑聯合會公布(bu)的田徑場地(di)設施(shi)手冊中有關場地(di)的規定(ding)。2)設計(ji)圖(tu)紙(zhi)是(shi)(shi)否(fou)完(wan)整(zheng)。除審查(cha)圖(tu)紙(zhi)做法是(shi)(shi)否(fou)完(wan)整(zheng)外，還應重點審查(cha)各(ge)種(zhong)邊界(jie)定(ding)位(wei)及詳細定(ding)位(wei)是(shi)(shi)否(fou)標(biao)注明確。3)是(shi)(shi)否(fou)有地(di)質資料。

1.2 設計(ji)交底及圖紙會審(shen)

在硅PU塑膠場地(di)施工(gong)時，應本(ben)著“事前控(kong)制、主動控(kong)制”的(de)(de)原則，結合(he)以往的(de)(de)經(jing)驗教訓(xun)，針對(dui)施工(gong)時有可能出現的(de)(de)問(wen)題，要求承包單(dan)位對(dui)報(bao)送重點(dian)部(bu)位、關(guan)鍵(jian)程序(xu)的(de)(de)施工(gong)工(gong)藝和確(que)(que)保工(gong)程質(zhi)量的(de)(de)措施進(jin)行研究、比較、確(que)(que)認后，形(xing)成統一的(de)(de)方案(an)，以工(gong)程例會的(de)(de)形(xing)式(shi)進(jin)行監理技術交底，并以書面的(de)(de)形(xing)式(shi)下發到施工(gong)單(dan)位，確(que)(que)保施工(gong)時各(ge)工(gong)序(xu)的(de)(de)順利(li)進(jin)行。

1.3 熟悉(xi)現(xian)場情況，及時做(zuo)好(hao)技術變(bian)更建(jian)議

對于硅PU塑膠場(chang)(chang)地施工，應(ying)注意查(cha)看現場(chang)(chang)場(chang)(chang)地土質(zhi)是否與地質(zhi)資料相(xiang)一致，如發現不相(xiang)符，做法不妥(tuo)或不符合場(chang)(chang)地建(jian)設要(yao)求，能比較好(hao)改進的(de)應(ying)及時向業(ye)主反映，并與設計(ji)單(dan)位洽商確定(ding)，形(xing)成設計(ji)文件，以(yi)便(bian)于依照(zhao)執行及備案。
