optimized planning
The Optimized Planning Industry Process Experience is for construction planners, project managers, and safety engineers to collaborate on a digital model that is true to the reality of the construction process.

It allows teams to simulate and validate critical project activities—even worker tasks—before arriving onsite.

The main ingredients for creating a fully optimized plan are the project design, construction sequences, and critical resources:

3D Model. The physical asset is represented in it’s completed form by a BIM or VDC (Virtual Design Construction) model.

Processes. Construction timeline and sequences are outlined in a Gantt chart or other timeline tool to illustrate the progression of the project.

Resources. The space, labor, and equipment utilized during a project are critical to simulating the construction process, but are often overlooked in the planning phase. Activities on the construction site often have even more impact on the bottom line than the design of the project itself. An analysis of the building environment throughout the build is necessary for planners to determine how the project will be built.

Optimized Planning considers the design, timeline, and critical resources like cranes and crews to produce an exceedingly detailed construction plan and dramatically reduce the risks and costs associated with the most critical components of complex projects.

Utilizing the Optimized Planning process helps users to:

  • Minimize costs by accurately predicting workforce requirements and onsite time needed for using costly material handling equipment, especially in congested areas
  • Dramatically reduce rework and delays through rapid recalculations using real-time data in the event of unforeseen activities
  • Improve worker health and safety by identifying risks early in the design and planning process
  • Optimize efficiency of the construction project by evaluating the best resource allocation, logistics, construction sequence, and other factors
  • Simplify communication by planning, visualizing, and working from data contained within one aggregated model

Defining and validating a precise plan prior to the execution of the actual construction job is made possible with a simulation system that can handle the model, schedule, and critical resource data.

Planners may then run realistic scenarios to validate sequences, optimize the construction schedule, and avoid project risks.

Spotlight on Lionel Lambourn of Syntegrate: Looking Beyond BIM to Improve Construction Efficiencies

By Akio

Admiralty Station, Hong Kong

Lionel Lambourn, director of Syntegrate, first gained familiarity with the possibilities afforded by BIM during his studies at the Southern California Institute of Architecture, before putting those possibilities to use at Gehry Technologies. During his tenure there, he helped set up the company’s Middle Eastern branches, using BIM tools in real-world applications.

It was that firsthand exposure to the ways that technology can boost efficiency in the construction process that led Lambourn to launch Syntegrate. The consultancy’s name was coined to describe the company’s focus on “synthesizing disciplines and integrating technologies.”

Why integrated technologies? As Lambourn quite simply explains, construction is a highly integrated discipline. It requires the work and knowledge of multiple disciplines to create something so complicated as a building, but it’s often at the intersection of trades where problems arise.

Today’s advanced software technology can easily be leveraged to ease the coordination required among building professionals and smooth the transitions of trades and materials.

“In this day and age I see integration of technology as the best way to address some of the accepted, in-built assortments of waste and inefficiency in the construction industry,” Lambourn says. “Our mission at Syntegrate is to leverage technology to realize our built environment more appropriately, more efficiently and more sustainably.”

An Environment of Waste

Waste and inefficiency, Lambourn says, are the single biggest challenges faced today by the architecture, engineering and construction industry.

“I believe waste and inefficiency overwhelm all the other issues and encapsulate all the challenges that we face in the industry,” he says. He offers an example to put this into perspective:

“By some reports, worldwide construction and buildings consume 40 percent of the world’s energy. However, we can conservatively estimate from available data that 20 percent of construction ends up as waste. To make these numbers more tangible, let’s put these numbers in the context of national GDP—worldwide construction is comparable to the size of China’s economy and each year the entire output of Spain is wasted.”

How can we do better?

Lambourn sees much of this waste and inefficiency could be solved by better coordination among contractors — a collaboration that could be easily facilitated by the integration of technology such as BIM.

Lambourn offers as a case in point Syntegrate’s work on the Admiralty Station, part of the South Island Line (East) Project, which will become the first four line interchange in Hong Kong.

The ongoing underground excavation and building work, which poses its own inherent risks, is being undertaken adjacent to the existing Island Line and Tsuen Wan Line, and the busy existing Admiralty Station – all within a densely populated area with many other underground structures in close proximity.

MTR Corporation, the owner of the project, recognizes the return on investment that they stand to gain from the comprehensive implementation of BIM on their many Projects, from construction through to operation.

The general contractor on the integrated Admiralty Station—a joint venture of Kier, Laing O’Rourke and Kaden (KLKJV)—were early adopters of BIM technology and are certainly at the forefront of the global construction industry in the implementation of BIM on their projects.

For Admiralty, the joint venture has chosen Dassault Systèmes’ 3DEXPERIENCE Platform as their BIM platform. Syntegrate works closely with the joint venture to refine its construction sequencing, from the coordination of excavation to concrete pours to formwork erection. By carefully scheduling each step, the general contractor has been able to execute each phase of this highly complex project with minimal rework, which in turn reduces schedule delays.

Moreover, the solution provides the joint venture with a visualization of the complicated underpinning work required to support the existing rail lines and platforms which remain in operation throughout construction.

Repeated simulations of the onsite work helps the construction team to effectively “practice” and perfect its planning, Lambourn says, so that when workers move onsite they are able to perform their work correctly the first time. This allows the joint venture to realize a dramatic reduction in waste of time and materials.

Broadening Technology Solutions

As projects become more complex, Lambourn believes that the use of BIM technology is a strong first step toward improving the collaboration of architecture, engineering and construction professionals. And he sees many opportunities to bring other technologies to bear, especially given the pace at which new technological advancements are happening.

“These days, we need to broaden our focus of technology to consider technologies such as 3D laser scanning, 3D printing, and even the use of drone technology to improve the way that a building is delivered,” Lambourn adds.

#technology for #AEC”

On the Admiralty contract, KLKJV utilizes 3D laser scanning extensively to capture the as-built conditions of the tunneling works at a level of precision that was not available several years ago and that is unachievable by orthodox survey methods.

“When the laser scan is introduced into the BIM platform, we can determine, exactly, how much over-break (excess excavation) has occurred and where any areas of under-break (insufficient excavation) exist. By repeated laser scanning as they proceed, the joint venture can optimize their works so that they achieve just the right amount of over-break with no areas of under-break, ensuring the highest levels of construction quality.”

Using integrated technology is but one solution to what Lambourn sees as a two-pronged approach to solving construction inefficiency.

Realistically, Lambourn says, “We would be naïve to think that the industry alone could tackle such a large problem of waste and inefficiency. Something like that has to come not only from the industry but also from a governmental level.”

Lambourn suggests that governments may need to step in to reward the reduction of waste and efficiency, ensuring this becomes a market factor that the industry must build into the way it does business.

Case in point: Lambourn notes that the industry still relies heavily on the delivery of 2D, paper drawings for contractual permissions.

“A building could be done completely paperless and much more efficiently through a 3D environment. However, governments need to come to the table and recognize that, and change the way that the legislation around the procurement of buildings is formulated so that there is not a real and contractual reliance on paper drawings.”

That doesn’t mean that architecture, engineering and construction practitioners should sit back and wait for governments to do something, however.

By becoming involved with organizations promoting and standardizing the use of BIM, the industry can help determine future technology requirements. Lambourn expects governments initiatives will spread more widely.

For example, the UK government has committed to what they call a “Level 2″ BIM implementation by the year 2016 and several months ago, the strategic plan for “Level 3″ BIM implementation was released under the title of “Digital Built Britain.”

Realistic Simulation Supports Expansion of the London Underground

By Akio

Dubbed “one of the most complex tunneling projects in the U.K.,” the Bond Street Station Upgrade (BSSU) project is being carried out to satisfy growing traffic demands within London’s busiest shopping district, the West End.

Upon its completion, Bond Street Station’s daily passenger numbers are expected to rise from 155,000 to 225,000.

A project this complex in nature has to consider the existing tunnel infrastructure, as well as the stress and strains imposed by the surrounding soil layers for the development of new tunnels.

Dr. Sauer and Partners was contracted to provide such tunneling expertise. The company took on responsibility for preliminary-to-detailed design and construction on all BSSU sprayed concrete lined (SCL) tunnels.
