Engineering Alliance by the Numbers

Digital Facility Lifecycle Solutions

Day & Zimmermann provides laser scanning and 3D data capture technology solutions to create and maintain a digital facility. This provides our customers with a scalable option that can be deployed at various stages in the lifecycle of the capital or maintenance planning process. Working within a digital facility, the assets can be virtually tagged and dynamically linked to databases to ensure safety, quality assurance/compliance, maintenance records/planning, and construction planning/progress verification. This solution provides our customers with a tremendous return on their investment, including cost and schedule savings, and the ability to reuse the data to establish work processes on future projects. Other benefits include:

  • Ensured Process Safety Management (PSM) compliance
  • Reduced field work – increased dimensional accuracy
  • Reduced turnaround time for scanning and data processing
  • Improved quality of engineering deliverables/coordination
  • Improved model reviews with project teams
  • Shortened engineering and construction durations through streamlined work processes
  • Improved constructability through better visualization of project
