To address the problems of budgetary inaccuracy, the lack of comprehensive or high-level management, and the existence of serious waste of auxiliary materials during the main construction phase of housing construction, a BIM-based method for calculating the auxiliary materials required for housing construction is proposed in this paper. The BIM model is firstly built according to structural construction drawings, the construction scheme and the construction specification and technology in the main structure construction stage; then, the usage of auxiliary materials is calculated, and the auxiliary material dosage report, construction drawings, and processing drawings are generated for purchasing, collectively processing auxiliary material and guiding construction at the same time. This paper improves upon the traditional auxiliary material management model and design via the implementation of a BIM application named zgBIMs according to the proposed method. The improved manage-ment model uses the generated auxiliary material dosage report, construction drawings, and processing draw-ings to centralize the processing of the required auxiliary materials, strengthen supervision in the process of material distribution and construction, and introduce a reward and punishment mechanism to control the attri-tion rate of auxiliary materials. In this paper, the successful implementation of the presented method and man-agement model is demonstrated as part of a comprehensive and experimental building project. The experimental results show that the proposed method can be used for the accurate calculation of the amounts of auxiliary ma-terials required to reduce the use and waste of auxiliary materials efficiently and thus save construction costs.

1. Introduction

The primary materials used in housing construction are steel, ce-ment, concrete, sand and stone. Gravel, support frames, scaffolding, templates, primary and secondary runner channels, split bolts, emery cloth, cotton and ramie fabric, electrodes and linoleum are all examples of auxiliary materials [11,37]. In this paper, the term “auxiliary building materials” denotes wooden templates, primary and secondary runner channels and support frames, which are widely used in housing con-struction and account for approximately 4–6% of the total cost of the main engineering work required for housing construction in China [10].

1.1. Research background

Because the construction industry consumes large amounts of natu-ral resources and energy, it must fulfill global criteria for sustainable

development through “green” buildings and construction. Green con-struction is now the main direction of development in the construction industry. Green construction involves conserving resources and reduc-ing waste as much as possible while still ensuring project quality and safety [9]. To satisfy the requirements of green construction and sustain-able development through the appropriate use of environmental re-sources while still maintaining project profitability and company competitiveness, increasing emphasis is placed on “delicacy” manage-ment [18,32] in building construction.

Nevertheless, the findings reported in this paper indicate that China#39;s housing-construction enterprises face the following common problems in the main construction phase.

  1. A lack of tools for accurately calculating auxiliary-material re-quirements. Most enterprises calculate auxiliary materials manually, with results that differ considerably from the actual amount required (here referred to as the “actual dosage”). This difference increases costs for enterprises and places great pressure on warehouses, transportation and rental, es-pecially for overseas construction projects (which require auxiliary materials to be shipped from national to local

摘要

1.引言

住宅建筑的原材料是钢材、混凝土、砂、石。砾石、支架、脚手架、模板、一级和二级运动员通道,对拉螺栓、砂布、棉、麻织物、电极和油布都是辅助材料为[11、37 ]的例子。在本文中,术语“辅助材料”指的是木模板,小学和中学的运动员通道和支撑架,可广泛应用于住宅建筑,约4–6%在中国住房建设所需的主要工程总成本帐户。 [10].

1.1.研究背景

由于建筑业消耗大量的自然资源和能源,它必须满足可持续的全球标准

绿色建筑与建筑的发展。绿色建筑是当今建筑业发展的主要方向。绿色建筑涉及到节约资源和减少废物尽可能多的同时仍然保证工程质量和安全 [9]. 为了满足绿色建筑的要求和可持续发展的环境资源的合理使用的同时仍然保持项目的盈利能力和企业的竞争力,越来越多的重点放在“精细化”管理[ 18,32 ]建筑。

然而,本文报道的研究结果表明,中国的住宅建设企业面临以下共同问题在主体施工阶段。

  1. 为准确计算辅助材料的要求缺乏工具。大多数企业手工计算辅助材料,其结果与实际需要量相差很大(这里称为“实际剂量”)。这种差异增加成本为企业和地方的仓库,巨大的压力,交通和出租,特别对于海外工程项目(需要辅助材料将从国家到localsettings,由于施工工艺和工人的施工习惯不同)。

  1. 由于缺乏精细管理,辅助材料受到“粗放式”管理。它是管理者要求工人进行施工,根据精细化管理原则的困难,工人可以把辅助材料随机在加工和施工。这不仅造成了巨大的浪费,增加了风险,而且增加了返工率和施工成本。

1.2. BIM及其在住宅建设中的应用

BIM是基于三维(3D)数字技术和底蕴,所有的信息都在建设项目全生命周期,提供与项目相关的信息详细表达[ 26,38,41 ]。随着BIM技术的不断发展,该技术在住宅建设中的应用越来越广泛。研究表明,在设计阶段,BIM技术可以用来把参与住房建设的各方统一起来。

施工阶段,BIM技术可以动态地管理整个施工过程 [2],提高施工质量[ 7, 39 ],降低施工成本,加快施工进度[3]大大降低未来楼宇维修成本 [34].

BIM的使用对房屋建筑有许多好处。迄今为止,研究住房建筑BIM的研究人员主要集中在建筑设计、施工过程监督、安全和项目成本估算等方面。然而,使用BIM精确计算辅助材料的要求和协助辅料精致管理没有得到重视。因此,有必要研究辅助材料的计算方法。[6,40].

1.3. 主要研究内容和目标

本研究的目的是用于计算基于给定的住宅建设和住宅建设技术规范房屋建筑主体施工阶段所需的辅助材料,提出并验证了基于BIM的方法。精确计算辅助材料的要求,降低了施工企业的辅助材料的成本,有助于实现“零库存管理”的辅助材料,并最终减少了辅助材料的购买量,节约建设成本。

此外,所提出的BIM方法可用于生成辅助材料的加工和施工图,使管理人员能够指导施工人员在施工和施工过程中完成任务。辅助材料的集中处理提高了利用率,防止了切割长管和将细木料放在小规模使用中的问题,最大限度的存在减少了辅助材料的浪费。最后,提出的模型和管理模型有助于建筑企业完善辅助材料管理,实现绿色施工。

这项研究有四个主要组成部分。

  • 在住宅建设的主要施工阶段,开发基于BIM的房屋建筑规范和住宅施工技术,精确计算房屋建筑的辅助材料,以解决辅助材料的问题。
  • 研究一种新的辅助材料管理模型,根据所提出的方法,帮助企业实现对辅助材料的精细管理。
  • 设计和实施一种名为zgBIMs的应用程序,可精确计算所需辅助材料的数量。
  • 对山西农业大学综合实验建筑项目的方法和管理模式进行验证。

2.辅助材料的计算方法

首先,有必要建立基于结构设计工作图的建筑构件BIM模型,并对其进行结构设计。

2.1.1.模型描述

根据建模方法,可以将三维模型分为线框模型、曲面模型或实体模型。作为辅助材料,主要用于建筑构件表面和表面

模型具有最高的绘制效率,本文采用曲面建模方法对模型进行建模。约束的Delaunay三角剖分[29,36]用于构建建筑模型的表面,从而描述建筑物中的洞[8,30,35]。为了使模型的编辑和管理,它们的属性被划分为三类:私有属性、公共属性和计算规则属性。私有属性是特定于给定组件的,而私有属性的变化只影响组件的当前状态,而公共属性对于具有相同结构的所有组件是通用的。例如,墙的类别和建筑中使用的材料和做法是公共属性,墙的立面、颜色、标签和透明度是私有财产。计算规则属性是辅助材料计算的规则。
