DOWL maintains in-house expertise in Environmental and Land Development, Water/Water Resources, Transportation, Civil Engineering and Geo-Construction.

At DOWL an outstanding safety and health record is paramount. This means strict regulatory compliance and developing our own best practices to enhance our performance. The core elements of our successful safety and health strategies are:


  • Leadership at the top
  • Confidence on the part of all employees
  • Creating and implementing a safety and health management system
  • Monitoring performance regularly
  • Ownership of safety and health by all employees
  • Accountability at all levels of our organization
  • Open sharing of knowledge and information



DOWL's EMR and incident rate continues to be low - and in the safety business that's a good thing. However, until there are zero incidents, we'll never be satisfied. That's why we continually work to improve our health and safety program.
