事前質量控制要點

1.1 熟(shu)悉(xi)施(shi)工圖紙(zhi)

建造一個合格的(de)運動場地(di)，是(shi)一項非常專業化的(de)體育工藝，專業設(she)計不(bu)同于通常民(min)用(yong)建筑，它應該根據(ju)國際田(tian)聯《田(tian)徑設(she)施手冊》和中國田(tian)徑協(xie)會《田(tian)徑競(jing)賽規則》最(zui)新規范、標準進行設(she)計施工。監理人(ren)員應重點審查圖(tu)紙中的(de)以下(xia)問題：

1)設(she)計說(shuo)明是否(fou)完(wan)善。主要審(shen)(shen)查說(shuo)明中是否(fou)符合國(guo)際(ji)田(tian)徑(jing)聯(lian)合會公(gong)布(bu)的田(tian)徑(jing)場地(di)(di)設(she)施手冊中有關場地(di)(di)的規(gui)定。2)設(she)計圖紙是否(fou)完(wan)整。除審(shen)(shen)查圖紙做法是否(fou)完(wan)整外，還應重點(dian)審(shen)(shen)查各種邊界定位及詳(xiang)細定位是否(fou)標注(zhu)明確。3)是否(fou)有地(di)(di)質資料。

1.2 設計交(jiao)底及(ji)圖紙(zhi)會(hui)審

在硅PU塑膠場地施(shi)(shi)工(gong)時，應本著“事前(qian)控(kong)制(zhi)、主動控(kong)制(zhi)”的原則，結(jie)合(he)以(yi)往的經驗教訓，針對(dui)施(shi)(shi)工(gong)時有可能出(chu)現(xian)的問題，要求承包單(dan)位對(dui)報送重點(dian)部位、關鍵(jian)程序的施(shi)(shi)工(gong)工(gong)藝和確(que)保工(gong)程質量的措施(shi)(shi)進行研究、比較、確(que)認后，形(xing)成統一的方案，以(yi)工(gong)程例(li)會(hui)的形(xing)式進行監理技術(shu)交(jiao)底(di)，并以(yi)書面的形(xing)式下發到施(shi)(shi)工(gong)單(dan)位，確(que)保施(shi)(shi)工(gong)時各工(gong)序的順利進行。

1.3 熟悉現場(chang)情況，及時做好技(ji)術變更(geng)建議

對于硅PU塑膠場地(di)施工，應注意(yi)查看現場場地(di)土質是否(fou)與地(di)質資料相一致，如發現不(bu)(bu)相符，做法不(bu)(bu)妥或不(bu)(bu)符合場地(di)建設要求，能比較好改進(jin)的應及(ji)時向業(ye)主(zhu)反映(ying)，并(bing)與設計單(dan)位洽商確定(ding)，形成設計文(wen)件，以便于依照執(zhi)行及(ji)備(bei)案(an)。
