FREQUENTLY ASKED QUESTIONS

Before we start

Can you do the design without visiting the site?

Yes, for many projects. With architectural drawings, photos and the equipment list we can design remotely. If the project requires it, we arrange a visit.

Are the drawings signed?

Yes, with the signature and professional license number of the person responsible, within the scope that license allows. When the code requires a licensed electrical engineer because of the type or size of the project, the design is coordinated and signed by an engineer with a current license in that jurisdiction.

How much does it cost?

It depends on the project size, the number of circuits or loads and whether a visit is needed. We send you a scoped quote before we start.

Can I buy directly from the bill of materials?

Yes. It includes quantities, wire sizes, ratings and specifications, so you can quote it with your supplier and buy only what you need.

Do you also do the installation?

We can support purchasing, supervise construction and do the final inspection of the installation.
