1990s renovation work on landmark European buildings, performed as design engineer — the systems designed then are still in service today. [Role + firm per project to be confirmed with Marcel]



Marcel spent his career inside large engineering firms [firm names — from LinkedIn], designing mechanical systems for buildings ranging from dentist offices to the European Parliament. He founded AWSDE to offer the same engineering without the large-firm cost structure.
Every AWSDE drawing set says the same thing in the title block: Drawn by: MSD. Checked by: MSD. The engineer who runs the calculations is the engineer who draws the systems, stamps the sheets, and answers the phone.
Describe your project. You'll hear back from the engineer directly — typically within one business day.
