Previous Work History
“As Caliagua Principal, Gus was SPR (Steve P. Rados Inc.) subcontractor on a fast track DWR project. Gus was on site regularly and solved all technical problems directly himself. He knew every detail of the project, he takes responsibility, and is a true on-site problem solver/decision maker.”
Frederix Doucedame- Project Manager/Estimator, Steve Prados Inc.
“As the representative of Caliauga inc., Gus makes every effort to provide not only the elements of the contract he is responsible for, but he also tries (and usually succeeds, to my knowledge) to provide a finished product that the client and Caliagua can both be proud of. Gus places great emphasis on the fact that “no shortcuts” be taken.”
