AECCafe Weekly Review December 9th, 2016

AECCafe’s Holiday Technology Wish List
December 8, 2016  by Susan Smith

 Most of what AEC professionals need and want is how to get their designs expressed, realized and built efficiently, accurately, quickly and on budget. The solutions to these challenges can be provided with a mix of software, cloud and gadgetry, much of which you will find here.

No car manufacturer in business would create an engine bay by interpreting a representative 2D drawing—yet it is still acceptable for AEC professionals to work that way.

Today’s complex buildings should no longer rely on fragmented communication through 2D drawings or pdfs, said Robert Beson of AR-MA (Architectural Research – Material Applications Pty Ltd.), in a recent presentation at the 3DEXPERIENCE Forum Asia Pacific South 2016.

Beson suggested that architects today have a responsibility to provide more than just design intent. When relying on 2D drawings, too much is left up to interpretation.

“It’s necessary to fully engage with the methods of construction, of manufacturing, assembly, logistics and installation,” Beson says. “We need to understand and engage our supply chain from concept through design.”

Adapting to New Processes

Moving to a collaborative platform based on parts and assemblies makes sense, but requires new skillsets from designers.

Today, every project AR-MA designs is comprehensively modeled in 3D.

Every project uses 3D laser point cloud scanning to verify work as it’s built onsite.

The shift requires architects to interact in new ways with fabrication and construction professionals.

Take connection brackets, for example. By combining 3D scanning and a just-in-time fabrication pipeline, it’s no longer necessary to design complicated 3-way adjustable brackets. The team can design simple laser cut plates, each of which are slightly different and ultimately improve the tolerances onsite.

The need for 2D drawings can be fully removed by laser cutting or engraving directions for assembly into the materials themselves.

To provide these fabrication-ready solutions, every member of the team at AR-MA writes code.

“It’s not enough just to model, and put together assemblies and parts, and think through the building process,” Beson says. “It’s crucial to engage with the means of production and be able to communicate with them. Often that means writing code and sending G-codes directly to the CNC machines.”

Comprehensive Modeling for Wynyard Walk’s Unique Components

For Wynyard Walk, a pedestrian walkway recently completed in Sydney, AR-MA was contracted to manage and execute detail design of the stainless cladding. The team had to deliver a fabrication-ready package of over 3,000 perforated stainless panels and lights, more than 50% of which were entirely unique.

Beson notes that it would not have been possible to work from 2D drawings of the mostly unique 3,000 perforated stainless steel panels at the Wynyard Walk pedestrian walkway.

The designers wanted a parametric model that was flexible enough to respond to ongoing design challenges.

The model had to accommodate an as-built primary structure, a glass reinforced concrete wall cladding, interfaces with the ceiling, and ongoing changes in the panel layout and perforations due to modifications in the façade mullions and setouts.

The contractor found the Façade Design for Fabrication powered by 3DEXPERIENCE platform best fit its needs.

Its integration of design and engineering, part and assembly paradigm, and scalability, among other features, allowed the team to produce a highly detailed and accurate 3D model of the entire project scope.

The integration of design, engineering and fabrication information made the 3DEXPERIENCE a strong solution for this project.

Not only did the comprehensive model prevent problems before they arose, but it allowed designers to minimize the number of part drawings by providing fabrication-ready geometry that was sent directly to the fabricator.

This saved time in the office and factory, and removed any error from misinterpretation of the 2D drawings.

For example, the tremendous time crunch made it necessary to release all fabrication information in batches. Façade Design for Fabrication helped the team to coordinate and track those batch releases, as well as any revisions.

Technical Support of Creativity

Beson pointed out that architecture has long been considered a creative endeavor, but what unifies the team at AR-MA is a belief that architects must unite creativity with technical ability.

“Both are necessary to produce the types of innovative and formative buildings our cities require today,” he says.

Canada’s Jobs Picture Improved Modestly in November
December 6, 2016  by Alex Carrick, Chief Economist at ConstructConnect

Article source: ConstructConnect

Canadian total employment in November rose by 11,000 jobs, according to the latest Labour Force Survey from Statistics Canada, marking a slowdown from the three prior months: October, +44,000; September, +67,000; and August, +27,000. July’s change was -32,000 jobs.

From January through November of last year, the average month-to-month gain in total employment in Canada was +12,000. For the same time frame this year, there has been an improvement to +15,000. If the economy were performing better, a figure closer to +20,000 per month would be expected.

The national unemployment rate dropped to 6.8% in the latest month from 7.0% in October. The decline is explained by a lower participation rate, which fell from 65.8% to 65.6%. In other words, a smaller percentage of the labour force was looking for work in November than in the month before.

There are some interesting differences in unemployment rates according to demographic groupings.

For all workers aged 25 to 54, the current jobless rate is lower for women (5.2%) than for men (6.3%).

For older individuals, − i.e., those aged 55-plus − the jobless-rate advantage held by women over men is even more pronounced, 4.7% compared with 6.6%.
