Core Purpose

Inspec’s core purpose is to improve the quality of life for our clients, the public, and our employees.

In the performance of our work, Inspec encourages a heavy emphasis on the following:

  • Maintaining our independence of manufacturers and contractors. This allows Inspec the freedom to explore a wide variety of possible solutions without bias so our clients can rest assured knowing we are working on their behalf.
  • Having a thorough understanding of both the nature and cause of the problem without pre-conception before developing the design solution.
  • Developing the design solution with long-term performance and sustainability in mind.
