About Us

Established in 2005, Challman Engineering has produced hundreds of quality projects in the Antelope Valley community and the surrounding areas. Our company started in a small office in Littlerock, California, and has grown into the premier engineering firm in the valley.

Using innovative technology, we apply our knowledge and experience as we engage with our clients to assess their goals and meet their needs at a cost they can afford. 

Our new Palmdale offices are equipped with state of the art software that develops a 3D model that enables the client to visualize a project before construction begins. Desired changes are able to be made in real time, allowing clients to make informed decisions regarding modifications. 

 

We are the parent company of CEI Build, Inc., a design-build company that moves a project from conception to completion. 

 

Challman Engineering, Inc. and CEI Build, Inc. are ready to help you with your next project, and we look forward to planning it with you.
