【摘要】：進(jìn)度計(jì)劃作為建設(shè)項(xiàng)目三大管理之一進(jìn)度管理的首要任務(wù),其合理與否對項(xiàng)目有重大影響。傳統(tǒng)施工項(xiàng)目進(jìn)度計(jì)劃的編制多由具有多年工作經(jīng)驗(yàn)的計(jì)劃編制人員來完成,尤其大型復(fù)雜項(xiàng)目,其進(jìn)度計(jì)劃編制對實(shí)踐經(jīng)驗(yàn)的依賴性更大,如此使得計(jì)劃編制過程帶有較大的主觀性,增大了編制結(jié)果的不確定性,削弱了施工進(jìn)度計(jì)劃的指導(dǎo)作用。施工進(jìn)度計(jì)劃編制的主要任務(wù)包括工作結(jié)構(gòu)分解、邏輯關(guān)系分析確定與作業(yè)時(shí)間估計(jì)等三個(gè)部分,將BIM技術(shù)與作業(yè)時(shí)間估計(jì)相結(jié)合,進(jìn)行基于BIM的作業(yè)時(shí)間估計(jì)方法的研究,有助于提高作業(yè)持續(xù)時(shí)間及項(xiàng)目工期的準(zhǔn)確性,增強(qiáng)進(jìn)度計(jì)劃現(xiàn)場指導(dǎo)作用,具有重要的現(xiàn)實(shí)意義。本文采用文獻(xiàn)查閱、推理分析等方法,對BIM技術(shù)、進(jìn)度計(jì)劃編制、施工作業(yè)持續(xù)時(shí)間估計(jì)、IFC標(biāo)準(zhǔn)等進(jìn)行研究。文章首先對傳統(tǒng)的進(jìn)度計(jì)劃編制方法及其過程進(jìn)行分析,總結(jié)了作業(yè)時(shí)間估計(jì)所需要的資料與數(shù)據(jù),分析整理了企業(yè)歷史項(xiàng)目數(shù)據(jù)及其作用,并確定了施工定額各消耗量(人工、材料、機(jī)械)的確定流程、技術(shù)手段、涉及部門及信息資料;其次研究了基于IFC的BIM體系結(jié)構(gòu)及信息描述與關(guān)聯(lián)機(jī)制,重點(diǎn)進(jìn)行了進(jìn)度管理領(lǐng)域作業(yè)時(shí)間估計(jì)方面IFC實(shí)體的擴(kuò)展,并研究了基于BIM的作業(yè)時(shí)間相關(guān)信息的提取與集成機(jī)制,確定了作業(yè)時(shí)間估計(jì)子模型的數(shù)據(jù)提取流程與集成流程;最后在前文研究基礎(chǔ)上,進(jìn)行了基于BIM的作業(yè)時(shí)間估計(jì)系統(tǒng)的設(shè)計(jì),主要設(shè)計(jì)了BQEED系統(tǒng)與CBRED系統(tǒng),進(jìn)行了詳細(xì)的系統(tǒng)架構(gòu)、運(yùn)行流程及界面設(shè)計(jì),以及CBRED系統(tǒng)案例知識庫基于XML的案例內(nèi)容集和案例結(jié)構(gòu)XML文件設(shè)計(jì),為實(shí)現(xiàn)作業(yè)時(shí)間估計(jì)提供途徑,幫助修正企業(yè)施工定額,提高作業(yè)時(shí)間估計(jì)的準(zhǔn)確度與進(jìn)度計(jì)劃編制水平,增強(qiáng)企業(yè)競爭力。
[Abstract]:As one of the most important tasks of construction project management, progress plan has a significant impact on the project whether it is reasonable or not. The preparation of the traditional construction project schedule is mostly done by the planner who has many years of work experience, especially for the large and complex project, whose progress plan is more dependent on the practical experience. This makes the process of planning more subjective, increases the uncertainty of the preparation results, and weakens the guiding role of the construction schedule plan. The main tasks of construction schedule planning include work structure decomposition, logic relation analysis and operation time estimation, combining BIM technology with job time estimation, and then studying the method of job time estimation based on BIM. It is helpful to improve the accuracy of work duration and project duration, and enhance the site guidance of schedule planning, which has important practical significance. In this paper, BIM technology, schedule planning and construction duration estimation are studied by means of literature review, reasoning analysis and so on. Firstly, the paper analyzes the traditional schedule planning method and its process, summarizes the information and data needed to estimate the job time, and analyzes and collates the enterprise history project data and its function. And determine the construction quota consumption (manual, material, mechanical) of the determination process, technical means, involving departments and information materials. Secondly, the BIM architecture based on IFC and information description and correlation mechanism are studied. This paper focuses on the extension of IFC entities in job time estimation in the field of schedule management, studies the extraction and integration mechanism of job time related information based on BIM, and determines the data extraction process and integration flow of the job time estimation sub-model. Finally, on the basis of the previous research, the paper designs the job time estimation system based on BIM, mainly designs the BQEED system and CBRED system, carries on the detailed system architecture, the running process and the interface design. The case knowledge base of CBRED system is designed based on the case content set and case structure XML file of XML, which provides a way to realize job time estimation, helps to revise the construction quota of enterprises, and improves the accuracy of job time estimation and the level of schedule planning. Enhance the competitiveness of enterprises.
