241、們學生運用所學的基礎理論、專業(yè)知識和基本技能進行建筑、結構、施工設計的重要實踐過程，涉及綜合運用建筑、結構、施工、設備、給排水和相關學科的基礎知識。在老師的指導和同學的幫助下，我完成了這次的畢業(yè)設計課題——濟南市高級技術學院辦公樓。</p><p>　　這次畢業(yè)設計，我們土木工程專業(yè)的學生要完成該工程從初步設計到施工完成的整個過程，可以說涉及知識面比較廣，比較全面！工程量也很大！</p><p

242、>　　在設計中，一方面要把所學的知識運用到設計、施工中去，熟悉國家有關規(guī)范、條例和規(guī)程并知道如何去查找規(guī)范里的相關條文；另一方面，由于現(xiàn)代化建筑一般都具有密度大，高度高，功能多，設備復雜，裝修豪華，防火要求和管理自動化水平高，需要各工種交叉配合。因此，通過這次畢業(yè)設計，擴大學生非本專業(yè)知識面也是十分重要的。</p><p>　　所以在這次畢業(yè)設計中，我們不僅僅溫習了以前所學習的專業(yè)知識還學習到了很多新的知識
