Nonresidential Construction Starts Trend Graphs – April 2017

Clichés are often true and it is the case that a picture can be worth a thousand words.

Below are six graphs recording 12-month moving averages of ConstructConnect ’s nonresidential construction starts.

When the value of the current month is higher than for the same month a year ago, the line will turn up; when lower, it will dip.

String a couple of similar positive or negative directional changes together over several months and one has a trend.

And that’s what the graphs are designed to do, show improving or deteriorating trends in a dozen major and more granular categories of construction work.

“BIM must extend beyond buildings to support infrastructure and Smart Cities” JONATHAN RIONDET, AEC Solutions, Dassault Systèmes

“BIM must extend beyond buildings to support infrastructure and Smart Cities” JONATHAN RIONDET, AEC Solutions, Dassault SystèmesMuch of the productivity-boosting potential of BIM for transforming the AEC industries has been inspired by the use of digital mockups in the manufacturing and aerospace industries.

Lately, engineering and construction companies have been inspired by the possibilities for improving infrastructure projects by adopting many of the same tools being used in architecture.

#BIM Standards @3DSAEC @aeccafe https://ctt.ec/JgH0V+”

This trend was at the heart of a recent session at BIM World. Jonathan Riondet, AEC industry solution technical director for Dassault Systèmes, presented the applications for BIM beyond buildings during a roundtable discussion in conjunction with representatives from engineering companies EGIS and SYSTRA.

Riondet has helped clients develop BIM solutions for infrastructure using the 3DEXPERIENCE platform, which doesn’t create a distinction between architecture and infrastructure—it’s one single platform with different modules that address the needs for both.

The challenge, however, is that the IFC standards have not yet caught up to this surging interest.

buildingSMART, the international home of open BIM, is working to develop IFC standards for infrastructure alignment—but forward-thinking civil engineers want more.

Standards are critical for collaboration, Riondet pointed out.

In many cases, engineers and contractors are adapting IFC data as there has not yet been pressure on the IFC standard to develop interoperability for bridge, highway, roads, and other infrastructure projects.

In markets like China, for example, construction practices move rapidly and technology tools must keep apace.

Riondet noted that Dassault Systèmes’ Chinese infrastructure clients in particular have been challenging the status quo by pushing for IFC standards outside the building scope.

This push is starting with the use of tools for the alignment of infrastructure. It is also being extended to the engineering and construction of bridges, rails, tunnels, dams, and more.

Infrastructures are demanding a solution not only for a bridge structure, for example, but also for the complete infrastructure project delivery.

As a result, Riondet said he is seeing customers use solution like 3DEXPERIENCE to develop specifications for how IFC for a bridge would be described.

In fact, Riondet mentioned one design group with which he has worked for five years that has been using BIM solutions for building bridges and highways, from design through a level of detail for fabrication.

Infrastructure and Smart City concepts, as those in Singapore and Rennes, are a natural extension for BIM from its use in buildings.

But to harness the full value of BIM, infrastructure engineers and contractors need the same level of interoperability and seamless continuity between model iterations.

ConstructConnect’s YTD Starts -2% after April Softens -7%
May 16, 2017  by Alex Carrick, Chief Economist at ConstructConnect

Article source: ConstructConnect

ConstructConnect announced today that its April construction starts, excluding residential activity, were -7% versus March. The usual seasonal pattern is for a 12% increase month to month at this time of year, as blustery winter mellows into gentler spring.

April of this year compared with average April results over the prior five years, 2012-2016, was +17.6%. Year-to-date starts so far in 2017 have been -2% compared with the same first four months of last year.

The starts figures throughout this report are not seasonally adjusted (NSA). Nor are they altered for inflation. They are expressed in what are termed ‘current’ as opposed to ‘constant’ dollars.
