前言

Foreword

 

 

 

 

目前的BIM发展,已经对传统的设计流程进行了充分的总结,搜集归纳了大量的二维设计的痛点和难点,也提出了大量的基于BIM的解决方案。我们在项目中,借鉴了一些成熟的技术来解决本项目的难点。在设计阶段,我们利用GIS数据生成现状场地,在三维场景中分析沿线用地情况,考虑最少的征迁范围,最小的施工影响,最优的跨越(铁路)方案,最佳的(与地铁施工的)穿插组织。结合桥梁模型,我们通过模拟项目施工过程,优化交通组织设计,分析互通分两期施工的条件并优化方案;另外,我们充分利用BIM的可视化,出图,参数化,算量,协同的功能,满足了业主提出的其他对于提高设计质量的要求。

 

The current BIM development has fully summarized the traditional design process, collected a large number of pain-points and difficulties in 2D design,and also proposed a large number of BIM-based solutions. In the project, we borrowed some mature technologies to solve the difficulties of this project. In the design phase,we use GIS data to generate the current site, analyze the land use along the 3D scene, consider the minimum scope of relocation, the minimum construction impact, the optimal span (railway) plan, and the best (with subway construction) ) Interspersed with tissue. Combined with the bridge model,by simulate

the project construction process, optimize the traffic organization design, analyze the conditions of the two-phase construction and optimize the scheme; in addition, we take full advantage of BIM's

visualization, plotting, parameterization, calculation, and coordination functions to meet other requirements proposed by the owner to improve the quality of the design.



 

BIM+GIS 可视化辅助决策:就三维数字场景展开讨论,提高决策的效率和准确性

BIM+GIS-aided visualization to support efficient and precise decision-making

 

彩虹快速路是杭州“四纵五横”快速路网系统中重要的一横,全长约 25.7 公里,本项目实施设计的是其中 7.49 公里的彩虹大道主线及相连接的高架、隧道、互通立交和平行匝道,总投资约 52.06 亿元。

 

The express-way network in Hangzhou consists of “four vertical and five horizontal”

trunk roads,in horizontal” trunk roads,

in which the 25.7 km Rainbow Express-way

is an important horizontal component. 

 

This project covers 7.49 km of the main lane (Rainbow Avenue), and elevated,roads,

,tunnels,interchanges and parallel ramps

connected to it.Total investment is about RMB 5.2 billion.

 

项目甲方希望能采用 BIM 技术,在前期方案拟定,设计深化,以及后期施工组织实施中,能及时发现问题并提前预防。

 

The project owner mandated to use BIM technology, aiming to timely detect and fix 

problems in initial design, design detailing

and on-site construction.

 

另外,复杂的沿线用地,与同期修建铁路之间的衔接需求,互通段主线与匝道的净空控制,复杂变化的断面带来的繁复出图工作,以及甲方对设计质量的精细化要求,都是本项目的挑战,需要 BIM 技术的助力。

 

Moreover, the project needs BIM to address

challenges such as complicated landscape,

transfer connection with a railway under

construction, precise clearance control

between intersections of the main road and

ramps,heavy load of drawing generation

caused by frequent and complicated

amendments in design, as well as high 

expectation of the project owner.

 

利用 GIS 及扫描数据生成现状场地,再结合 BIM 模型,生成三维数字场景,以便方案更直观地呈现。在三维场景中分析建设环境、场地条件、区域路网和周边构筑物等相关条件,通过多角度漫游查看、模型测量来快速获取到相关信息。通过 BIM 模型进行快速出量和施工模拟,比较不同设计方案的优缺点,综合考虑不同方案的线位和关键节点,帮助施工组织,特别是与周边其他项目的协调。在多轮决策会议上,甲方召集十几个相关部门就三维数字场景展开讨论,提高决策的效率和准确性。

 

The project team uses GIS and scan data to

generate models of the construction site,and

then generate 3D digital scene to visualize

the schematic design.Construction conditions are analyzed in the 3D scenarios,

including the construction environment,field

conditions, road network in the area and

peripheral buildings. Related information is

acquired with multi-angle roaming view and

model-based measurement.

 

BIM models also enable quantity take-off

and construction simulation.Thanks to BIM application, options of construction  are

compared and key line positions and

connections highlighted,to facilitate field

construction and coordination with surrounding projects.

 

The project owner convenes meetings,where

relevant departments and entities study the

3D digital scene together for fficient and 

precision decision making.

 

项目团队采用Autodesk AEC Collection 作为 BIM 解决方案,完成了从方案、设计到施工交底的模型数据无缝传递的工作流程。

 

The project team used Autodesk AEC Collection as BIM solution,to constitute an end-to-end work-flow,enabling seamless data transfer from schematic design to detail

design and to construction technical 

clarification.

 

 


“BIM 技术作为现阶段桥梁建设的前沿技术已逐步普及,应用价值点突显。模型是 BIM 的载体和基础,如何快速实现高架、互通等复杂桥梁的精确建模一直是困扰我们的难题。利用 Civil 3D、dynamo 和revit 的组合使用,我们成功找到了通过桥梁“数据”快速创建精确模型的解决方案,也为隧道、管廊等其它基础设施的建模指明了方向。”

 

As a frontier technology in bridge design and construction, BIM has shown outstanding value and wongrowing application. We used to struggle with precision modeling of elevated bridge,intersections and other complicated structures.

By combining Civil 3D,Dynamo and Revit,however,we manage to overcome the difficulties and create accurate modeling with bridge“data”.The experience is also inspiring for the modeling of other infrastructure projects, such as tunnels and pipe corridors.

数据化建模:利用 Dynamo 打通 Civil3D 和 Revit 之间的数据通道,实现了全过程基于统一数据源的建模流程

Digital modeling workflow based on a single data source. Dynamo is used as the data gateway between Civil3D and Revit.

 

 

项目团队紧紧围绕数据开展设计工作,用BIM 攻克二维设计的难点。 利用 Dynamo 打通 Civil3D 和 Revit 之间的数据通道,实现了全过程基于统一数据源的建模流程,研究出了一整套高架互通的建模方法,规范了设计流程并提高了建模效率,建立了企业级高架桥梁建模标准。通过 Dynamo 的可视化编程功能,实现了三维空间曲线的绘制、构件定位、异性构件的创建,解决了在Revit 中创建高架互通的难题;同时高效地整理了桥梁模型中各个截面参数,进行了数据的导入和存档。

 

The project team takes a data-based

approach and addresses challenges in

traditional 2D design with BIM.Dynamo is

used as the data gateway between Civil3D

and Revit. A modeling workflow is set up for

the entire process, based on a single data

source. At the same time,a set of methods

to model viaduct structure intersections is

developed.

These efforts help standardize design 

process, improve modeling efficiency and 

enact corporate standards for viaduct bridge

modeling. Visualization programming of 

Dynamo makes it possible to model viaduct

structure intersection in Revit with 3D curve

drawing, component positioning and irregular components modeling.

Moreover, parameters of each cross section

in the bridge model are standardized for

data import and storage.

 

在Civil3D 中首先完成桥梁的平纵曲线建立, 输出设计数据到 Excel 表格,预先规定好表格中行列的数据类别。

 

Horizontal and vertical curves of the bridge

are modeled in Civil3D, before being

exported to Excel spreadsheets,where data

type for each row and column is configured

in advance.

 

通过 Dynamo 中编写建模程序,读取设计数据,创建桥梁上部、下部和附属结构。

 

Dynamo is used to program bridg ,models,

access design data and create the upper,

lower and auxiliary structure models of the

bridge.

 

桥梁上部结构建模,通过程序读取桥梁中心线数据和截面轮廓,定义起始桩号和跨径, 快速生成某一标准联的标准段桥梁模型。对于加宽段,可以通过 Excel 表格数据驱动参数化的截面轮廓,修改表格数据实现桥梁模型的尺寸调整;对于互通段,上部结构更为复杂,需要将箱梁的实心和空心分两次建模; 实心部分建模时,利用桥梁数据创建定位线,结合 Revit 自适应族,定位放置各截面,最后生成鼻端实体;空心部分建模时,通过自适应轮廓族创建空心箱室,最后相互剪切完成最终箱梁模型。

 

Upper structure modeling. By reading data

of the axle-center and section profile within the program, the project team defines

starting pile number and span,and then

quickly generates a standard model for

section units.For extended sections,Excel

spreadsheet data is used to generate

parametric cross-section profiles and adjust

the size and parameters by data

modification.

 

The upper structure has very complex

intersection parts, making it necessary to

model separately the solid and hollow parts

of the box girder. When modeling the solid

part,bridge data is used to create the

positioning line,locate and place each 

section with the Revit adaptive  family and

finally generate the model of approaching

noses. 

When modeling the hollow part, the adaptive

profile family is used to create the hollow

box room and finally cut it out to get the box

girder model.

 

桥梁下部结构建模,通过程序调取在结构设计时进行梳理并以标准格式储存在 Excel 表格中的各类桥墩设计数据,自动生成参数化桥墩。再通过桥墩所在的桩号和偏移数据,自动完成桥墩的布置。

 

Lower structure modeling. The program

accesses design data of bridge piers in

standard Excel format, and automatically

generates parametric model of the piers.

With pile number and offset data of the

piers,their layout is automatically scripted.

 

桥梁附属设施建模中,标线设计是难点之一。利用 Dynamo 快速把 CAD 平面标线投影至实体上部结构表面,完成标线的制作。数据化建模还可用于快捷建立防撞栏,路灯等附属设施。

 

Auxiliary facilities modeling. Design of the

marking lines is a major challenge.

Dynamo is used to project CAD plane

markings to the 3D upper structure.

Digitalized modeling can also be used to

quickly set up models of crash barriers,street

lights and other auxiliary facilities.

难点示意图

最后,利用Dynamo对已建桥梁模型进行快速高程检查,及时发现设计中的问题,提升了BIM设计的精度。

 

Finally, Dynamo is used for quick elevation

inspection, so as to detect potential 

problems and make the design more 

accurate.



基于 BIM 的施工交底:采用Navisworks 对桥梁施工工序和方法进行模拟,采用 Dynamo实现数据抓取

BIM-aided constructiontechnical clarification:

Navisworks is used forconstruction simulation and Dynamo is used to captureand export data from BIMmodels.

 

 

彩虹快速路设计过程中,将施工需求前置考虑。提前分析了复杂节点的可施工性,施工过程中的交通组织,大型施工设备的布置等。采用 Navisworks 对桥梁施工工序和方法进行模拟,直观展示施工步骤、施工时间和影响范围。本项目由多家施工单位分标段实施,在设计阶段就综合考虑了不同标段的衔接问题,结合BIM的可视化展示和施工模拟动画,准确的表达了设计意图,为施工单位展开施工组织设计提供依据。这一方式也得到了项目业主的认可。

 

 

Construction needs are front-loaded in the

design phase.The team analyzes feasibility

of construction for complicated intersections,

traffic plan during construction,deployment

of large-sized equipment and so on.

Navisworks is applied to simulate 

construction sequences and methods,and

visualize construction steps, duration and

scope of impact.This project is divided into

sections and commissioned to multiple

contractors,so the coordination between

sections is also factored in during design.

 

BIM visualization tools and construction

animation are used to accurately present

the design concepts,offering clarity to 

contractors.This practice is also recognized

by the project owner.

 

 

 

施工过程中应用 BIM 模型的一大难点是快速有效的数据抓取。这意味着不仅要创建精准的 BIM 模型,还要使模型信息能够互用,施工单位能够快速抓取特定信息,并以此实现进度管控、材料管控等。本项目使用Dynamo 实现数据抓取,导出到易于查看和编辑的通用 Excel 表格中,作为向施工单位传递核心数据的交付形式,供施工单位获取材料、工程量、空间关系等信息,更方便地编制施工组织计划,可以满足现阶段数据交底的大部分需求。

 

Another challenge in BIM application is how

to capture data quickly and effectively.

Accurate BIM models and interoperable

information exchange are instrumental

for contractors to capture specific 

information on progress and time control.

This project uses Dynamo to capture and export data to common Excel spreadsheets

which are both viewer-friendly and editable.

The spreadsheets deliver core data to

contractors, ensuring access to key 

formation such as materials, engineering

work amount and spatial relationships,

making it easier to organize construction

and meet the requirement of data disclosure.




BIM 助力提质增效:开发桥梁建模程序,建模效率是常规建模的3 倍左右,并可在同类项目中重复使用

BIM boosts quality andefficiency:The program makesmodeling 3 times efficientand can be re-used in similarprojects.

 

 

在彩虹快速路项目的深化设计阶段,利用Autodesk AEC Collection 产品组合,通过可视化编程开发了一整套基于准确数据的桥梁建模程序,克服了三维环境下桥梁设计的难题,简化了大量重复性建模工作,大大减轻了工作量。

建模的效率是常规建模的 3 倍左右,还可简化模型检查、模型修正的工作流程,并实现数据的抓取。未来在类似项目中,设计师只需要使用新的数据,并微调建模程序,就能一键完成模型创建,效率可进一步提升。

 

In detail design phase, 

Autodesk AEC Collection is used.

By visualized programming a whole set of

bridge modeling programs based on 

accurate data is developed.

This reduces the workload of repetitive

modeling and makes it easier to design

bridge in 3D environment.

 

This approach is 3 times more efficient than

trditional practice.It simplifies the work-flow

of model checking and modification and also

enables data capture. In future projects of

similar profile, designers only need to update

data and models can be created with a click

of the mouse. The efficiency will be further

improved.

在彩虹快速路项目的 BIM 应用过程中我们意识到,BIM在项目中介入的时间点越早,运用的面越广,运用深度越深,就能发掘出越多的价值。未来我们会针对 BIM 模型与其他系统平台之间数据格式标准问题,

以及不同专业间的数据壁垒问题进行更深入的探索,解决信息在平台间、专业间的无缝传递和互用。我们相信,随着 BIM 技术越来越深入的应用,一定会带来基础设施项目工作流程的变革和优化,引领行业的创新和突破!

 

BIM application in the Rainbow Express project shows

that the earlier, wider and deeper BIM is deployed, 

the more value can be harvested.In the future, we will

conduct more in-depth explorations on data format

standardization between BIM and other platforms, so

as to enhance data interoperability among disciplines

and domains for seamless data transfer. Deeper 

penetration of BIM will redefine and optimize the

work-flow of infrastructure projects, 

breeding industry-wide innovation and disruption.
