北京天坛医院新区，北京/建筑设计

The BIM application of Beijing Tiantan Hospital relocation project covers all disciplines including architecture, structure, electromechanical, hardbound and municipal. BIM model is applied to construction coordination in the later stage, and the construction party also adopts BIM system for on-site construction organization and production scheduling.

具有传统优势的专科门诊楼又居于整个项目的最南端，领航着整个建筑群。专科门诊楼外皮构思取材于医院特色专科神经外科的核心——脑神经元抽象的符号作为建筑母题，彰显出建筑的现代感和别具一格的建筑特色。

The specialist outpatient building with traditional advantages is located at the southernmost end of the whole project, leading the whole building complex. The concept of the outer skin of the specialized outpatient building is based on the core of the specialized neurosurgery of the hospital - the abstract symbol of brain neurons. As the architectural motif, it highlights the modern sense and unique architectural characteristics of the building.

设计组在设计过程中通过Autodesk RevitArchitecture 构思多种方案，最终采用无规律形体，初期在Autodesk A utoCAD平面中进行推敲，后期采用Autodesk R evit Architecture深化设计。

During the design process, the design team conceived a variety of schemes through Autodesk revitarchitecture, and finally adopted irregular shapes. In the initial stage, it deliberated in the Autodesk a utocad plane, and in the later stage, it adopted Autodesk R evit architecture to deepen the design.

该项目为2014年北京市政府重点项目，也是目前北京在施体量最大的医院工程。项目主体是混凝土框架剪力墙结构总建筑面积35.06万平方米，由10座单体组成，集门诊、急诊、康复、病房、科研等功能于一身。

The project is a key project of Beijing Municipal Government in 2014 and the largest hospital project under construction in Beijing. The main body of the project is a concrete frame shear wall structure, with a total construction area of 3500600 square meters. It is composed of 10 single buildings, integrating outpatient, emergency, rehabilitation, ward, scientific research and other functions.

▼ 创建BIM模型，实现全专业数据集成

Create BIM model to realize full professional data integration

钢筋专业作为本项目施工业务的主要组成部分，如何快速准确地创建符合要求的钢筋BIM模型，成为本项目建模工作的主要任务之一。利用Revit软件已无法满足钢筋建模的要求，故项目选用广联达GGJ软件完成钢筋模型的创建工作，并与其他软件创建的土建、机电模型一起导入广联达BIM5D软件，实现多专业数据集成。

As the main part of the construction business of the project, how to quickly and accurately create a BIM model of reinforcement that meets the requirements has become one of the main tasks of the modeling work of the project. The use of Revit software can not meet the requirements of reinforcement modeling, so the project selects Guanglianda GGJ software to complete the creation of reinforcement model, and imports Guanglianda bim5d software together with civil engineering and electromechanical models created by other software to realize multi-disciplinary data integration.

▼ 管线综合优化、指导施工

Comprehensive optimization and guidance of pipeline construction

北京天坛医院新址项目BIM应用

本工程施工过程中，管线铺设错综复杂，需在施工前进行深化设计以解决原设计与实际施工中的问题，利用传统方式进行生化设计效率低下，无法快速高效地完成管线优化工作，为此本项目利用BIM技术进行图纸深化工作,在A7楼地下二层的A-F~A-L/A-2~A-6样板间位置，在深化图纸建完模型之后发现不同专业的管线出现重叠和空间利用不合理的现象，管综优化后，满足了规范要求的最小间距要求（包括管道保温层在内），提高了净空，避免了工程返工造成的损失。

During the construction of the project, the pipeline laying is complicated, and the detailed design needs to be carried out before the construction to solve the problems in the original design and actual construction. The traditional biochemical design is inefficient and can not complete the pipeline optimization work quickly and efficiently. Therefore, the project uses BIM Technology to deepen the drawings, which is located in the A-F ~ A-L / A-2 ~ a-6 model room on the second floor of A7 building, After deepening the drawing and building the model, it is found that the pipelines of different disciplines overlap and unreasonable space utilization. After the comprehensive management optimization, the minimum spacing requirements required by the specification (including pipeline insulation layer) are met, the clearance is improved and the loss caused by engineering rework is avoided.

▼ 基于BIM模型，快速实现二次结构排布

Based on BIM model, the secondary structure layout can be realized quickly

本项目中二次结构作为建筑工程的组要组成部分，因为其细部节点繁多，由于施工过程中难以进行精细化设计，以致于施工现场对原材料切割的随意性较大，较普遍地存在着严重浪费、损耗的现象。为此项目在2015年3月开始进入二次结构施工，在此之前的2014年底，BIM技术人员就将搭建好的二次结构模型，构造柱进行排砖布置，利用排砖功能，不仅快速直观，而且可以出砌体需用量，给物资采购提供了依据。目前正与现场排砖情况进行校核对比工作。

In this project, the secondary structure is an important part of the construction project. Because of its many detail nodes, it is difficult to carry out fine design in the construction process, so that the cutting of raw materials on the construction site is random, and there is a phenomenon of serious waste and loss everywhere. Therefore, the project began to enter the secondary structure construction in March 2015. Before that, at the end of 2014, BIM technicians will build the secondary structure model and arrange the brick arrangement of structural columns. Using the brick arrangement function, it is not only fast and intuitive, but also can calculate the masonry demand, which provides a basis for material procurement. At present, it is checking and comparing with the on-site brick layout.

▼ 图纸系统管理、快速查询

Drawing system management and quick query

本工程施工过程中涉及图纸多而繁杂，需要对图纸进行系统梳理便于快速查看管理。总包收到业主审核完成图纸共3135张，共计录入BIM系统2083 张，并将图纸与模型对应挂接，并根据搜索功能实现模型与图纸的双向查看。针对项目170多条变更图纸的重批，在图纸模块都进行了相应申报状态的动态跟踪，原来需要2-3人1小时完成的任务，现在只需要在高级检索中输入条件即可查到，速度比传统模式相比快了数倍。

There are many and complicated drawings involved in the construction process of the project, so it is necessary to systematically sort out the drawings for quick viewing and management. The general contractor received 3135 drawings reviewed and completed by the owner, including 2083 entered into the BIM system, linked the drawings with the model, and realized the two-way viewing of the model and drawings according to the search function. For the re batch of more than 170 changed drawings of the project, the dynamic tracking of the corresponding declaration status has been carried out in the drawing module. The task that originally required 2-3 people to complete in one hour can now be found only by inputting conditions in the advanced retrieval, which is several times faster than the traditional mode.

▼ 工程进度模拟分析

Simulation analysis of project progress

本项目利用传统进度管理方式，工程进度分析管理复杂，工作量大，效率低下，无法及时了解项目各进度情况及快速做出调整，为此项目在BIM系统中将现场施工情况以及场地工况环境进行实时模拟，发现潜在进度风险的同时还给出项目开工到竣工的资金分布和资源分布，作为成本管控的有效依据。将每日施工日志与计划任务挂接，通过三种不同开始时间和结束时间反应真实的进度情况并进行预警，每次开生产会时直观交底，快速制定整改方案。

The traditional schedule management method is used in the project. The project schedule analysis and management is complex, the workload is heavy and the efficiency is low. It is impossible to understand the progress of the project in time and make rapid adjustment. Therefore, the project simulates the on-site construction situation and site working condition environment in real time in the BIM system, While discovering the potential schedule risk, it also gives the capital distribution and resource distribution from the commencement to the completion of the project as an effective basis for cost control. Connect the daily construction log with the planned task, reflect the real progress and give early warning through three different start and end times, make intuitive disclosure at each production meeting, and quickly formulate the rectification plan.
