The Project

Located at the mouth of Tamsui River that flows through the capital Taipei, the Danjiang Bridge is integral to the infrastructure upgrading program of northern Taiwan. Commissioned through a competition by the Directorate General of Highways, Taiwan, R.O.C., the bridge will increase connectivity between neighbourhoods and reduce through-traffic on roads within local town centres.

By also reducing traffic from the congested Guandu Bridge upriver, the Danjiang Bridge will greatly improve the northern coast traffic system and enhance accessibility throughout the region with the rapidly expanding Port of Taipei/Taipei Harbour, the region’s busiest shipping port.

The Team

The winning design team comprised a joint venture collaboration between architects Zaha Hadid Architects based in London, acting as design consultants; lead structural engineer was Leonhardt, Andrä & Partner in Germany and Sinotech Engineering Consultants in Taiwan acting as local engineering consultants.

Simulation in Architecture, Engineering, and Construction

Monday, November 20th, 2017

The following article is excerpted from SIMULATION IN ARCHITECTURE, ENGINEERING AND CONSTRUCTION. To read more, download the full white paper here.

PRODUCT, NATURE, AND LIFE IN AEC

These are extraordinary times for civil engineering. Innovative structures such as hyper-loops, undersea hotels and made-to-order 3D-printed buildings, which were just concepts a few years ago, are no longer considered to be in the realm of fiction. These novel structures need to be designed for either transporting people through natural surroundings, protecting them from natural surroundings or allowing them to interact with natural surroundings.

The commonalities that underlay these structures consist of intricate linkages between product, nature and life. The same is true for conventional civil engineering structures, including buildings, bridges, tunnels and dams.

We need to think about product, nature and life together, not only for creating innovative designs, but also for providing optimal functionality, ensuring safety and safeguarding sustainability for ecological well-being.

Product, nature and life, therefore, need to play a conjoined role during planning for large engineering projects, such as city developments, large transportation projects, as well as dams and irrigation works.

How can we include product, nature and life in the design processes for civil structures? This will need to be done through realistic simulations that take into account precise geometry and material properties, realistic representations of physical and natural processes, and rational predictions of experiences by people.

Such simulations, in addition to the obvious need for ascertaining structural safety, also need to include the construction processes and sequences along with reliable estimates of construction and maintenance costs.

COMMON INDUSTRY CHALLENGES

Large construction projects often exhibit cost overruns and delays due to unforeseen events or design changes during construction.

As is well known, a judicious balance between cost, time and quality needs to be maintained in any construction project in order to have the resulting product as profitable, safe and sustainable as possible.

In a construction project, the architects and structural engineers first need to come up with a conceptual design that is appropriate for the intended function of the structure. Potential structural loads need to be identified, and the conceptual design needs to be guided by the efficiency of how these loads get transmitted within the structure and distributed to the foundations.

Any errors or inappropriate design choices at this stage can have significant time and cost implications on the final outcome. If the structural components are pre-fabricated, then these and the final structure need to be designed based on the ease of manufacturing the pre-fabricated parts, which can often contain specially designed new materials.

Also, the transportation of these parts and the final assembly processes need to be considered. A complete study on how early design choices affect the construction process, time and costs is, therefore, necessary.

Moreover, such studies need to be done quickly and also need to provide comprehensive data in order to enable architects and engineers to make proper comparisons between different conceptual designs.

Once the conceptual design has been chosen, engineers need to come up with an appropriately detailed final design. As the construction gets under way, some parts of the structure may need to be altered from their original design.

In these circumstances, one needs to be able to quickly identify the implications of any structural modifications on the safety and reliability of the final product. Also, the final design needs to be updated and information on the ensuing modifications needs to be accurately and promptly passed along to the engineers at construction sites.

ROLE OF SIMULATION

In architecture, virtual or graphical simulation models can help in arriving at conceptual designs, taking into account wide ranges of criteria, such as layout, positioning, landscaping and lighting. Also, realistic rendering can be used to help make depictions lifelike, adding to their value for clients.

In engineering, virtual representations can be used to idealize structural geometrical configurations. These configurations can then be used in computational analyses to predict structural deformations and stresses resulting from applied loading and support conditions.

Subsequent to such simulation analyses, the predicted data values can be visualized and examined. Based on these data values, engineers can ascertain the strength, stability and safety of the proposed structure, and can then finalize the structural design.

In construction, the finalized design is then used for material estimation and ordering, planning the construction sequence and managing the construction process using appropriate simulation tools.

As one can see, simulation helps in all three phases of any civil engineering project—conceptual and architectural design, engineering design and construction. Although individual tools are available to simulate these three phases separately, the use of such tools may result in potential loss of information when passed between different phases of the project.

click-to-tweetTweet: Simulation helps in all 3 phases of a #civilengineering project: conceptual/architectural, engineering, construction @aeccafe @3DSAEC https://ctt.ec/eme9O+

Civil engineering projects, hence, need simulation tools that seamlessly connect the architecture, engineering and construction phases. One such simulation tool is available from Dassault Systèmes.

Structure Design for Fabrication on the 3DEXPERIENCE® platform from Dassault Systèmes has been specifically developed to provide engineers and architects with a unified capability to virtually represent conceptual designs, perform engineering analyses, analyze construction sequences and manage construction projects all together, while keeping track of individual components. It provides a unique representation of the project as a whole, one which several users can remotely access in order to obtain information according to their individual needs. Any change in any component can be reflected throughout the project, including the effects on project schedule, and also likely implications on the structural loading and response.

In addition to Structure Design for Fabrication, Dassault Systèmes also provides solutions using Abaqus® simulation software for complex simulations and analyses, including for pre-stressed and reinforced concrete, for simulating the altered behavior of damaged structures, for geomechanics analyses for tunnels and foundations, and for seismic response analyses of complex structures.

“Future Testing” for Civil Engineering

Thursday, October 26th, 2017

The ideas presented in earlier posts on Future Testing (excerpted from Replacing Problem-Solving with Future Testing) can be applied to the discipline of engineering.

Future Testing for Engineering Firms

Traditionally, engineering firms review the architect’s conceptual designs and independently develop their engineering drawings. This is a wasteful step, which duplicates work and can misinterpret the architect’s intent. This disconnect between the designs also makes it incredibly difficult to test new ideas or incorporate changes from the architect.

Future Testing bridges the digital gap.

It provides the ability for all stakeholders to collaborate on and visualize a virtual mockup of the project from start to completion in digital form, improving speed and building trust that the desired outcomes will be met.

How CadMakers Applies “Future Testing”

Thursday, October 19th, 2017

Future Testing is a process that leverages virtual design and construction, simulation, and rapid iterations. With Future Testing, AEC project stakeholders are able to anticipate issues and opportunities early, reduce risk, take advantage of innovative ideas, and gain an edge on the competition.

An excellent example of a company employing the Future Testing method is CadMakers Inc., a construction and manufacturing technology company.

They work closely with AEC businesses to streamline projects from design to construction, leveraging leading engineering software solutions. Their design approach includes modeling all the building systems — architectural, structural, mechanical, electrical and plumbing, civil and geotechnical — and mapping them virtually in an accurate, virtual 3D model. Then, they get everyone — the project architect, engineers, and various subcontractors — together to view the model and crowdsource solutions to identified problems.

Understanding the “Future Testing” Cycle

Thursday, October 12th, 2017

Every building and infrastructure design is unique. Whether a project is an artistic work or a more utilitarian design, it has unique requirements for piping, ductwork, structure and other elements that must be designed and coordinated in context.

These elements are typically left to later detail design stages of the project. Modernizing craftsmanship with Future Testing allows the 3D digital model from the architect to be extended and enhanced with detailed construction information. It’s then used to virtually construct the building and learn from that experience before doing work in the physical world.

These innovators use precise digital models to simulate the construction and the sequence of steps needed to build it, and iterate on this “digital mockup” multiple times to learn and improve.

In this way, Future Testing makes the first-time building a unique, “one of a kind” structure as efficient as if the company had made it for the 100th time!

click-to-tweetTweet: #FutureTesting makes each 1-of-a-kind structure as efficient as if it’s made for the 100th time @3DSAEC @aeccafe https://ctt.ec/2UOfq+

Future Testing also allows AEC companies to incorporate downstream feedback on constructability by collaborating on the virtual model with makers to build in downstream efficiency. Then, as they gain real-world experience executing the project, they continue to update the models with better ways of working, and run simulations to prove them out.

This way of working shortens the feedback loop so they can apply new methods to the current project, learning as they go and “leaning out” the process at every phase.

BIM and the G20 Meeting Hall

Thursday, July 20th, 2017

LU ZHI-HONG, YASHA

Article by LU ZHI-HONG, General Manager, Zhejiang YASHA Decoration Co., Ltd., BIM Center; Member, China Graphics Society BIM Committee; Deputy Editor of BIM Standards for Interiors and Curtain Walls, China Building Decoration Association.


When the 2016 G20 summit was planned to be held at the Hangzhou International Expo Center, Zhejiang YASHA Co., Ltd. took on the major project for the core meeting area.

This construction project involved dynamic designs, complicated construction techniques, a short timeframe, and special security requirements.

The overall design and construction work was very challenging, particularly the G20 main meeting hall.

The Building Information Modeling (BIM) team at YASHA used on-site 3D laser scanning, parametric modeling, streamlined design and fabrication, and other BIM techniques to help designers and project managers flawlessly complete their tasks and ensure the seamless construction of the G20 main hall.

Hangzhou, China | @3DSAEC @aeccafe https://ctt.ec/fdt1u+

Background and Goals for BIM on the Project

The Hangzhou International Expo Center is a landmark project for the city of Hangzhou. It was selected as the site of the 2016 G20 summit.

Because of the site’s special functions and the short construction timeframe, construction proved to be extremely challenging. Most difficult was the complicated design and high construction standards for the G20 main hall.

To address this challenge, our company began preparing our BIM technology well in advance of the project. Our company put forth its full effort, organizing designers, builders, and BIM personnel into a working group to employ BIM technology during the design and construction phases to ensure high standards. This allowed us to achieve our goal of high levels of quality, efficiency, and control.

AEC Industry Trends: Driving Toward Connection, Digitization, Transformation

Thursday, June 29th, 2017

In his recent Architecture, Engineering & Construction Industry Trends presentation, Marty Doscher, Vice President, AEC Industry, Dassault Systèmes, identified four accelerating trends that are driving transformative changes across the industry:

  • Higher usage of Design for Manufacture and Assembly (DFMA), prefabrication, and modular construction.
  • More data-driven decision-making as a result of greater BIM adoption.
  • Expansion of Building Information Management (BIM) beyond design—in all stages of the project lifecycle, and by users across all disciplines.
  • Growth of augmented and virtual reality (AR/VR) as a social industry experience.

click-to-tweetTweet: 4 growing AEC trends: #prefab, data-driven decisions,
expanded #BIM, & #ARVR | @aeccafe @3DSAEC https://ctt.ec/M5fWd+

As these industry trends build momentum, demand is growing for solutions to overcome the barriers to greater success.

For example, with increasing BIM adoption, Doscher expects to see a further increase in the use of VR as a design tool that boosts collaboration.

The 3DEXPERIENCity “Experience Room” is one example of how AR/VR tools work for AEC: stakeholders are projected into a collaborative workspace through which experts from government, business, urban planning, infrastructure design, and so on, can work together in harmony to define a city’s future.

The Shortcomings of BIM

BIM solves some of the AEC industry’s problems, but is not a total solution. BIM alone is incomplete.

click-to-tweetTweet: “#BIM alone is incomplete.” @MartyDoscher
@3DSAEC @aeccafe https://ctt.ec/Rp726+

Most projects are still over budget and behind schedule—even now, more than 15 years after BIM was introduced.

Today’s document-centric BIM methodology is still unable to break down silos among stakeholders. Too much energy is spent managing lines of communication that, when broken, lead to RFIs and heavy administrative costs.

Plus, design, construction, and operations remain separate from one another. Once a facility is built, the operations team may receive BIM data. However, this data is insufficient for what is needed to support long-term maintenance. Instead, the operations team typically creates their own “digital as-built” of the facility with the information they need.
