事前質量控制要點

1.1 熟悉施工圖(tu)紙

1)設(she)計說明(ming)是(shi)(shi)否(fou)(fou)(fou)完(wan)善。主要審(shen)查(cha)(cha)說明(ming)中是(shi)(shi)否(fou)(fou)(fou)符合(he)國際(ji)田徑聯合(he)會(hui)公布的田徑場地設(she)施手(shou)冊中有(you)關場地的規(gui)定(ding)。2)設(she)計圖(tu)(tu)紙是(shi)(shi)否(fou)(fou)(fou)完(wan)整。除審(shen)查(cha)(cha)圖(tu)(tu)紙做法是(shi)(shi)否(fou)(fou)(fou)完(wan)整外，還應(ying)重點審(shen)查(cha)(cha)各種邊界定(ding)位及(ji)詳(xiang)細定(ding)位是(shi)(shi)否(fou)(fou)(fou)標注明(ming)確。3)是(shi)(shi)否(fou)(fou)(fou)有(you)地質資料。

1.2 設計交(jiao)底及圖紙(zhi)會審(shen)

在硅PU塑膠場地施(shi)工(gong)(gong)(gong)(gong)時(shi)，應本著“事前控制、主動控制”的(de)(de)原(yuan)則，結合(he)以往(wang)的(de)(de)經驗教(jiao)訓，針(zhen)對施(shi)工(gong)(gong)(gong)(gong)時(shi)有可能(neng)出(chu)現的(de)(de)問題，要求承(cheng)包單位對報送重(zhong)點部位、關鍵(jian)程序的(de)(de)施(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝和確(que)保工(gong)(gong)(gong)(gong)程質量的(de)(de)措施(shi)進(jin)行(xing)研究(jiu)、比較、確(que)認后，形成統一的(de)(de)方案，以工(gong)(gong)(gong)(gong)程例會的(de)(de)形式進(jin)行(xing)監理技(ji)術交底，并以書面的(de)(de)形式下發到施(shi)工(gong)(gong)(gong)(gong)單位，確(que)保施(shi)工(gong)(gong)(gong)(gong)時(shi)各工(gong)(gong)(gong)(gong)序的(de)(de)順利進(jin)行(xing)。

1.3 熟悉現場情(qing)況(kuang)，及時做好技術變更(geng)建(jian)議(yi)

對于硅PU塑膠場(chang)地施工，應(ying)注意查看現場(chang)場(chang)地土質是否與(yu)(yu)地質資料相(xiang)一致(zhi)，如(ru)發現不(bu)相(xiang)符，做法不(bu)妥(tuo)或不(bu)符合場(chang)地建(jian)設要求，能(neng)比(bi)較好(hao)改進的應(ying)及(ji)時向(xiang)業主(zhu)反映，并與(yu)(yu)設計單位洽商確定，形成設計文(wen)件，以便于依照執(zhi)行及(ji)備案。
