Global Construction Industry Outlook

  • The global construction industry is expected to grow by an average of around 5.2 percent between 2018 and 2021, with the US, China and India expected to hold approximately 50 percent share worth $87 trillion, in incremental construction spend over the next 15 years 
  • Integrated project delivery is expected to be an emerging trend, enabling successful implementation and potential benefits of this outsourcing model in large-scale projects in the US 
  • Reduction in lifecycle cost and time are the key factors that led to an increase in the usage of technologies like BIM (3D&4D), laser scanning, 3D printing and smart building systems in the global construction sector

Global Construction-Industry Overview

The global civil construction industry is projected to grow from $5.9 trillion in 2017 to $6.79 trillion in 2021. This increase is primarily driven by the proposed government spending on infrastructure projects, primarily in Asia 
LATAM and APAC accounted for more than half of the world’s construction output in 2016 and by 2020; they will have a share of ~55 percent

Developed Regions

  • NA: Stronger infrastructure and residential will be the key determinants of the construction output in the region. The region is poised for stable growth until 2021
  • WE: European construction will grow 2.7 per cent this year – the pace will slow down clearly from last year’s 3.5 per cent.Growth will continue in 2019 and 2020 but at a slower rate, and construction will no longer be the European engine of growth

Developing Regions 

  • APAC: The percentage contribution in the global construction spend is expected to reach close to 45 percent in 2020. Though China’s construction faces a slowdown in growth, it still remains the prime market, with 60 percent share in the region  
  • LATAM:  The region is facing a slow growth rate, which is expected to continue for the next three years. Brazil’s construction industry is shrinking in real dollar values, while Argentina and Mexico continue to be the bright spots with better growth rates

Global Construction—Design Technology 

3D laser scanning

  • 3D laser scanning can be used in reproducing dimensions and positions of the object digitally, further turning them into a point cloud image 
  • 3D laser scanning of building structures will support offsite design recommendations, which saves time and costs 
  • Big projects are handled by having multiple scans from different angles and linking them all together to get an image, which is then exported to CAD or BIM programs to get a 3D model or drawing

BIM

  • BIM is now being incorporated at all levels on the construction projects 
  • The physical building is constructed digitally by creating a virtual model, which reduces the risk of mistakes or discrepancies and also for cost saving
  • Delivers spatial coordination on construction projects
  • Tracking and monitoring construction development in the cloud reduces errors and redundancy
  • Assessing documents, work lists, punch lists, field reports electronically
  • Handling electrical systems to peak performance

Other Design Software

Different technologies that are currently being used in the construction industry for engineering and design are DataCAD, ArchiCAD, CADKEY, ConSteel, REVIT, NavisWroks, StruCad and Nemetschek, as well as Corel Draw and Atlantis
