Get to know Steve from the people he’s helped.
ENGINEER EXPERT WITNESS
We tried the case you worked on last week and the jury reached a unanimous verdict (12-0) on Friday, finding in favor of our client.
It was a complete victory. Steve, thank you again for your work in this case.
Paul R., Attorney
WATER INTRUSION EXPERT SERVICES
“We purchased our home three years ago and have been dealing with significant water intrusion. The stucco was removed and replaced, the windows were fully replaced, and the home is still leaking. We’ve since had to remove interior walls and drywall due to moisture and black mold.
L.S., Homeowner
Your guidance was incredibly helpful, and I appreciated how thoughtfully you helped me think through next steps. Thanks again, Steve!“
ENGINEERING LEGAL EXPERTISE
I’ve had the opportunity to work closely with Steve Viani over the past several years on a complex and technically demanding project.
Steve’s engineering assessments were detailed, methodical, and always grounded in clear technical reasoning. He approached every aspect of the project with a level of care and accuracy that gave me a great deal of confidence in the work being produced.
His ability to communicate complex engineering concepts in a way that was understandable and actionable was invaluable.

PROJECT MANAGEMENT SERVICES
Steve and I have worked together for over 20 years on a variety of projects where I manage the field work and Steve manages the client, paperwork and conformance to specifications.
On numerous occasions he has successfully identified and negotiated change orders for the heavy civil work we performed. He understands the construction process and has always kept us out of trouble and profitable.
Ed B., Superintendent, Sacramento Drilling
TECHNICAL LITIGATION SUPPORT
Steve was retained to provide expert opinions regarding a construction defect case against our client on a $1.7 million custom home.
He quickly realized our client was not involved during the time period defective construction was performed and only during a short period after the earthwork, foundation and structural work were performed.
Steve reviewed the depositions and advised us this was correct and gave us responses we used during negotiations to settle this matter with a de minimis payment by our client. We intend to use him again.

CONSTRUCTION MANAGEMENT
For the past 3 years, you have been working hard to get our landslide repaired. Your design, and selection of the remedial contractor, allowed the project to be finished and we got our deck back!
You skillfully handled our neighbor and prevented her from stopping the project on several occasions. My wife and I want to thank you for your patience and perseverance in getting this completed.
T. To, Homeowner
CONSTRUCTION DEFECTS EXPERT
I wanted to let you know that your analysis of the engineering design, structural deficiencies and wind loads was critical in establishing liability and causation, and successfully challenging the defense experts’ opinions and their purported engineering approach.
Your work enabled me to achieve a settlement that was extremely favorable to our client.
Anthony P. Fritz, Esq., Herrig & Vogt, LLP
ENGINEERING & DESIGN
Steve assisted me in my dealings with Sacramento County over a 10 year period concerning building permits and was instrumental in getting final approval for my multi-million dollar horse facility.
Steve provided engineering, design, construction inspection and helped me navigate the maze the County set up to obtain permits. He saved me hundreds of thousands of dollars!

DESIGN
Thank you for your excellent design.
