Experience

I have worked on large central utility systems for over 40 years, starting with power plants in the 1970's through 1990's, and then working as a consulting engineer for industrial, institutional, governmental and large commercial customers on a wide variety of mechanical systems, both 'green field' and retrofits and upgrades. My speciality is steam and condensate systems, and hydraulic analyses of both steam and hydronic systems, but also have extensive experience with heating hot water, cooling tower, and compressed air systems, as well as HVAC systems.

A note about professional design services

I do not offer professional design services - although I maintain my professional registration, I do not sign/seal drawings, specifications or other construction documents to non-design firms. My deliverables mainly consist of feasibility reports, energy efficiency studies and review and comments on other mechanical design documents, as well as 'reverse engineering' Legacy Fortran code. I do offer design services to other Architectural/Engineering design firms on a case by case basis.
