【摘要】：工程算量的提取是基于BIM的建设工程项目重要的环节,现有的算量软件(比如广联达、鲁班)可对目前常用的建模软件Revit模型导入其平台下算量,但部分模型数据可能会丢失而且对转换模型和构件的名称等有严格要求,适用性较差。Revit作为目前国内使用最为广泛的BIM软件之一,工程量的提取具有非常高的精度,但是其体积扣减规则和明细表功能并不能满足我国《GB50500-2013_建设工程工程量清单计价规范》的要求。为实现基于Revit平台工程量提取的本地化,避免使用第三方软件二次建模,本文通过Visual studio2012开发工具引用Revit API接口使用C#编程语言开发插件,并在Revit平台下建立了BIM预算模型,利用该插件对模型构件体积扣减规则进行重置,并进行构件编码,计算导出工程量清单文件,实现了模型工程量快速准确的提取,验证了基于Revit平台工程量提取本地化的可行性,提高了工程量计算的工作效率和精度,减少材料浪费,降低了管理成本和预算风险。当前很多施工单位的钢筋分项工程不再采用外包模式而采用自行下料的方式,但面临缺乏相关钢筋下料人才的问题。研究一种能够节约人力、物力成本的钢筋下料方法已成为是施工单位要解决的关键问题之一。本文通过研究一种改进遗传遗传算法和Revit API接口来求解钢筋优化下料问题,在Revit平台下创建钢筋模型,运行插件快速计算钢筋的下料方式,该方法的优势在于它能避免大量冗余及不可行解以接近最优解(钢筋利用率最高)的情况下计算每根原料钢筋的下料方式,并使得钢筋余料最长,这极大的提高钢筋的利用率,在工程施工成本管理中具有重要意义。
[Abstract]:The extraction of engineering calculation quantity is an important link of construction project based on BIM. The existing calculation software (such as Guanglianda, Luban) can import the calculation amount to the current commonly used modeling software Revit model under its platform. Revit, as one of the most widely used BIM software in China at present, has very high precision in extracting engineering quantity, because some model data may be lost and the names of transformation models and components are strictly required, so the applicability of revit is poor. However, its volume deduction rules and parts list function can not meet the requirements of the GB50500-2013_ bill of quantities valuation code. In order to localize the extraction of engineering quantity based on Revit platform and avoid using the second modeling of third-party software, this paper refers to Revit API interface to develop plug-in with C # programming language through Visual studio2012 development tool, and establishes the BIM budget model under Revit platform. The plug-in is used to reset the volume deduction rules of the model component, code the component, calculate and export the bill of quantities file, and realize the rapid and accurate extraction of the model quantity. The feasibility of localization of engineering quantity extraction based on Revit platform is verified, and the efficiency and precision of engineering quantity calculation are improved, the material waste is reduced, and the management cost and budget risk are reduced. At present, many steel bar sub-projects in construction units no longer adopt outsourcing mode but adopt self-cutting method, but face the problem of lack of relevant personnel for steel bar cutting. It has become one of the key problems to be solved by construction units to study a method of cutting steel bar which can save manpower and material cost. In this paper, we study an improved genetic algorithm and Revit API interface to solve the problem of steel bar cutting optimization, create the steel bar model under the Revit platform, and run plug-in to quickly calculate the cutting method of steel bar. The advantage of this method is that it can avoid a lot of redundancy and infeasible solution to calculate the cutting mode of each raw steel bar under the condition of approaching the optimal solution (the highest utilization rate of steel bar), and make the residual material of steel bar longest, which greatly improves the utilization rate of steel bar. It is of great significance in the cost management of engineering construction.
