About the credentialProfessional practice
A clear basis.A considered approach.
I’m Martin Lettvin, CPE, PMP. My work connects electrical estimating, construction scope, and the information that supports a decision.
How I work
Ask useful questions. Make the reasoning visible.
Technical credibility comes from understanding the work and explaining the basis clearly. That principle guides both the estimate and the tools behind it.
01
Construction context
Keep quantities connected to installation, interfaces, and the conditions in which the work will be performed.
02
A reviewable basis
Document what is included, what is assumed, and what remains unresolved. Make those distinctions easy to find.
03
Clear communication
Match the level of detail to the decision, while preserving the reasoning needed for a useful review.
Perspective across
