Industry Issues

More Work,
Less People

Workforce insights show job postings steadily increasing and job searches steadily decreasing. A strong economy means more work and fewer people; efficiency and effectiveness are essential.

More Complex,
Less Expertise

Technical Professionals specializing in complex project delivery are harder to find, especially in owner organizations. Smart tools allow fewer experts to do more, and the less experienced to remain engaged.

More To Do,
Less Productivity

Since 2000, the growth of productivity in construction has fallen notably behind other major industries. To stay competitive, construction projects must embrace new digital tools to increase worker efficiency.

More Data,
Less Insight

Data has historically turned hindsight into insight; the future lies in turning insight into foresight. The modern pace of construction and engineering will depend on efficient, cost and resource-conscious analytics to stay competitive.
