2、在的質(zhì)量和安全問題</p><p>　　質(zhì)量控制和安全問題對項目經(jīng)理來說變得越來越重要。施工過程中的設備缺陷或故障可能會導致非常大的成本。即使有輕微缺陷, 也可能需要重新建設使設施運營受損。導致成本的增加和延誤結果。在最壞的情況下，故障可能導致人身傷害甚至死亡。在施工過程中的事故可能導致人身傷害和巨大的花費。保險，檢驗和監(jiān)管的間接成本迅速增加，會導致直接成本的增加。好的項目經(jīng)理應盡量確保在第一時間完成任務，并且在

5、施工過程中都需要考慮各種因素。</p><p>　　在施工過程中以講究一致性作為質(zhì)量的衡量標準，質(zhì)量要求的設計和合同文件中的說明將變得極為重要。質(zhì)量要求應該是明確的、可驗證的，能使項目中的各方都能夠理解的一致性要求。本章的大部分討論均涉及到發(fā)展和建設的不同質(zhì)量要求，以及確保符合性的相關問題。</p><p>　　建設項目中的安全性也在很大程度上影響到規(guī)劃設計過程中的決策。一些設計或施工計劃

6、本身就是又危險又很難實現(xiàn)的，而其他類似的計劃，則可以大大降低事故發(fā)生的可能性。例如，從施工區(qū)域內(nèi)修復巷道使得交通分道行駛可以大大降低意外碰撞的可能性。除了這些設計決策，在施工過程中安全在很大程度上取決于教育，提高警惕，合作。工人應對可能發(fā)生意外保持時刻警惕，避免不必要的風險。</p><p><b>　　2組織的質(zhì)量和安全</b></p><p>　　在施工過程中，各

7、種不同的組織均可對質(zhì)量和安全進行控制。一個常見的模式是由一個組負責質(zhì)量保證而另一個組則主要負責集團內(nèi)的安全組織。在大型的組織中，各部門致力于確保質(zhì)量和安全，可能會指定專人來承擔這些具體項目的責任。對于較小的項目，項目經(jīng)理或助理可能會承擔相應責任。在任一情況下，確保安全和質(zhì)量建設是項目經(jīng)理在除人事、成本、時間和其他管理問題以外必須重點關注并全面負責的。</p><p>　　檢查人員和質(zhì)量保證人員將代表各種不同的組織

8、共同參與一個項目。跟項目直接相關的各方都可能有自己的質(zhì)量和安全檢查，包括業(yè)主，工程師/設計師，和各種構造公司。這些檢查員可以從專業(yè)的質(zhì)量保證機構組織選擇擔任。除了現(xiàn)場檢查，材料樣品通常會由專門的實驗室測試，以確保其權威性。為了保證符合監(jiān)管要求，相關部門也將參與其中。常見的例子是當?shù)卣ㄔO部門的督察，環(huán)境機構，和職業(yè)健康與安全機構。</p><p>　　美國職業(yè)安全與健康管理局（OSHA）與獲批準的國家檢驗機構合

9、作，定期對工作場所進行實地考察。OSHA的檢查人員必須依法對所有違背標準的行為進行采證。以保障安全標準規(guī)定的各種機械措施和程序; 例如，梯子的安全有超過140個法規(guī)。在極端不符合標準上面法規(guī)的情況下，安全檢查員可以停止在一個項目的工作。然而，只有一小部分的建筑工地是由OSHA督察巡視的，大多數(shù)施工現(xiàn)場的事故并非由違反現(xiàn)有標準造成的。因此，安全問題在很大程度上應由現(xiàn)場管理人員而非公共督察負責。</p><p>　　

10、而施工過程中的眾多參與者都需要檢查人員的服務，也不能過于強調(diào)檢查人員只檢查質(zhì)量控制的過程。好的質(zhì)量控制應該是一個項目團隊所有成員的首要目標。管理者應承擔維護和提高質(zhì)量控制的責任。員工參與質(zhì)量控制包括引入了新的思路都應該被獎勵。最重要的是，質(zhì)量改進可以作為提高生產(chǎn)率的催化劑。良好的質(zhì)量控制可以通過提出新的工作方法，避免返工，并避免長期的問題，達到自給自足。業(yè)主應促進良好的質(zhì)量控制，并尋求能保持這樣的水準的承包商。</p>&

11、lt;p>　　除了參與質(zhì)量控制的各種組織機構，質(zhì)量控制問題在幾乎所有的建筑活動功能區(qū)均出現(xiàn)過。例如，確保準確和有用的信息是保持質(zhì)量性能的重要組成部分。質(zhì)量控制的其他方面包括文件控制（包括在施工過程中的變更），采購，現(xiàn)場檢查和測試，以及設施的竣工驗收。</p><p><b>　　3工作和材料規(guī)范</b></p><p>　　工作質(zhì)量的規(guī)格是設備設計的一個重要特性

12、。要求的質(zhì)量和部件的規(guī)格代表了必要的文件來描述一個設備的一部分。通常情況下，這個文件包含了施工期間使用的設備設計文件和公認的規(guī)范的任何特殊規(guī)定，作為參考。</p><p>　　工作質(zhì)量一般規(guī)格在許多領域都是在如美國材料與試驗協(xié)會（ASTM），美國國家標準協(xié)會（ANSI），或施工規(guī)范協(xié)會（CSI）等組織的刊物上發(fā)表。不同規(guī)格的形式為特定類型的建設活動，如由美國焊接協(xié)會頒發(fā)的焊接標準，或特定設施的類型，如由美國協(xié)會的

13、國家公路和運輸官員頒發(fā)的公路橋梁的標準規(guī)范。這些一般規(guī)格必須進行修改，以反映當?shù)氐臈l件，政策，提供的材料，地方性法規(guī)及其他特殊情況。</p><p>　　施工規(guī)范通常由一系列的具體操作指令或禁令組成。例如，下面的文章說明了一個典型的對在這種情況下的挖掘結構的規(guī)范：</p><p>　　符合標高和尺寸正負0.10英尺的容差范圍內(nèi)的計劃顯示，從地基和基礎延伸足夠的距離，允許放置及拆除混凝土模板

14、，安裝服務，其他建筑，并進行檢查。在挖掘挖掘地基和基礎時，當心別影響基坑開挖。用手挖掘并最終分級來填置鋼筋混凝土。調(diào)整（挖掘的）最底層到需要的路線和坡度，留下堅實的基礎去填充堅實（的混凝土）。</p><p>　　這一組規(guī)范要求應用判斷，是由于有些項目不能精確地指定。例如，開挖必須延長“足夠”的距離，以便進行檢查和其他活動。顯然，“足夠”這個詞，在這種情況下，可能會受到不同的解釋。相反，一個規(guī)范，公差內(nèi)加或減十分

15、之一英尺則是直接測量。然而，由于網(wǎng)站的設施或特征的具體要求， 可能會使得十分之一英尺的標準公差變得不合適。書寫規(guī)范通常需要在假設有關各方在諸如“充足”與預指定所有操作的努力和可能的解釋不準確的話雙方的部分合理的行為之間的權衡。</p><p>　　近年來，性能規(guī)格已經(jīng)被開發(fā)運用于許多施工作業(yè)。這些規(guī)范是指所要求的性能的成品設施或質(zhì)量，而不是指定所需的施工過程中的規(guī)范。而如何從其中獲得此性能的具體方法則是留給建筑承

16、包商的。例如，傳統(tǒng)規(guī)格為瀝青路面中指定的瀝青材料，瀝青組合物的攤鋪溫度，壓實過程。相反，一個性能規(guī)格瀝青所需的詳細性能是關于路面的抗?jié)B性及強度等。如何達到所期望的性能水平則要依靠鋪路承包商。</p><p><b>　　質(zhì)量控制（Ⅰ）</b></p><p><b>　　1全面的質(zhì)量控制</b></p><p>　　在施工

17、質(zhì)量控制一般包括投保符合材料和工藝上最低準則，以便根據(jù)設計，以確保設備的性能。這些最低標準都包含在上一節(jié)中描述的規(guī)范。對于符合保險的目的，隨機抽樣和統(tǒng)計方法通常用于為基礎，接受或拒絕工作完成，材料批次。一批拒絕是基于不符合或違反有關設計規(guī)范。這種質(zhì)量控制的實踐過程在下面的章節(jié)中描述。</p><p>　　在這些傳統(tǒng)的質(zhì)量控制方法的一個隱含的假設是可以接受的質(zhì)量水平，這是不良品的允許分數(shù)的概念。由一個組織進行供應商

18、或工作組獲得的材料進行檢查，如果估計有缺陷，但是所占百分比是在可接受的質(zhì)量水平，讓供應商和工作組來判斷判斷是否通過驗收。如果是材料或貨物的問題則是在產(chǎn)品交付后校正。</p><p>　　與此相反，質(zhì)量控制這種傳統(tǒng)的方法是全面質(zhì)量管理的目標。在這個系統(tǒng)中，施工過程中的任何地方都不允許有次品。而完美的目標卻是永遠無法達到的，它提供了一個目標，讓組織永遠不會滿足于它的質(zhì)量控制程序，使得缺陷在年復一年的大量減少。這個概念

19、和質(zhì)量控制的方法最初是開發(fā)制造在日本和歐洲的公司，但已蔓延到許多建筑公司。最有名的質(zhì)量改進的正式認證是國際標準化組織ISO 9000標準。ISO 9000強調(diào)良好的文檔，質(zhì)量目標和一系列的周期規(guī)劃，實施和審查。</p><p>　　全面質(zhì)量管理是一個對質(zhì)量的承諾，表現(xiàn)在組織的各個部分，通常涉及許多元素。設計審查是確保安全和有效的施工程序的一個主要元素。其他因素包括大量的人員培訓，轉移檢測產(chǎn)品缺陷的質(zhì)量控

20、制員的責任，并不斷維護設備。在質(zhì)量圈中的工人小組定期開會，提出質(zhì)量改進的建議，但工人參與改進質(zhì)量控制往往是形式化的。材料供應商也需要確保交付貨物的零缺陷。首先，從供應商的所有材料進行檢查，有缺陷的商品被分批次退回。能證明自己信譽優(yōu)良的供應商，則可以在之后完成檢查。</p><p>　　質(zhì)量控制的傳統(tǒng)微觀經(jīng)濟學的觀點是有缺陷的項目的“最優(yōu)”的比例。努力實現(xiàn)比這更大的最佳的質(zhì)量會大幅增加檢驗成本，降低員工的工作效率。

21、然而，許多公司都發(fā)現(xiàn)，致力于全面質(zhì)量控制可以產(chǎn)生可觀的經(jīng)濟效益，這是一個曾經(jīng)一直不受重視的傳統(tǒng)方法。全面質(zhì)量控制使得返工，廢鋼和保證與庫存相關費用均減少，并且改善工作人員的積極性和工作決心?？蛻敉矚g更高質(zhì)量的作品，并會為其高質(zhì)量支付高價。其結果是，完善的質(zhì)量控制成為了一個競爭優(yōu)勢。</p><p>　　當然，全面的質(zhì)量控制是很難應用的，尤其是在建設中。各設施的獨特性，勞動力的變化性，眾多分包商，教育和程序進行

22、必要的成本投資，使項目全面質(zhì)量控制的實施難度大。然而，一個組織雖不能保證達到完美的目標但卻一直致力于提高質(zhì)量，那么它可以是一個真正為大家造福的組織。</p><p><b>　　附外文原文：</b></p><p>　　Quality Control and Safety during Construction</p><p>　　1 Qual

49、l specifications of work quality are available in numerous fields and are issued in publications of organizations such as the American Society for Testing and Materials (ASTM), the American National Standards Institute (
