About Dennis

Dennis has 30 years of engineering experience related to building mechanical systems.

He graduated from Portland State University with a Bachelor of Science degree in Mechanical Engineering in 1993.

Dennis joined Northwest Engineering Service in Tigard, Oregon. They specialized in Test and Balance of mechanical systems for buildings with a focus on making systems work right. He moved into Third-Party Commissioning when the Commissioning industry began in the late 1990’s. His experience with the firm included a combination of design review and fieldwork. The fieldwork involved testing, adjusting, and troubleshooting of new and existing mechanical systems. Dennis has excellent “hand-on” engineering experience with troubleshooting building systems, finding problems, and making systems work right. He analyzes the problem in context of the whole system and recommends solutions that fix the problem rather than creating more.

In 2015, Dennis focused his experience on forensic engineer and expert witness work. He has helped resolve a number of disputes concerning design and construction problems found in buildings. The building types range from residential through large commercial and institutional. He has conducted numerous on-site examinations and reported upon his findings and recommendations. He enjoys investigative work and explaining technical issues to non-technical persons in terms they can understand.

After 25 years with one company, Dennis decided to step out on his own. He founded Conser Forensics in April 2019. He provides consulting mechanical and forensic engineering and expert witness services dealing with disputes in the construction industry. With an engineering focus on heating, ventilation, air conditioning and plumbing systems he also consults with building owners to:

• Assess equipment condition
• Determine causes of repeating pipe leaks
• Determine causes of failed systems
• Technical consultation for problems or system replacement
• Review construction drawings and specifications
• Assess of engineering choices
• Review work of contractors
