Good regards for safety, completed additional works regarding decoration.

I just wanted to say a BIG thank you to everyone who has worked to complete the build of our new classroom. From the beginning of the project, with initial site meetings, to the completion the whole team has been very professional l, friendly and taken pride in their work which is reflected in our truly amazing classroom.

To say that this 3 month modernization was a Herculean task would be an understatement.

I remain convinced at this time, 2 weeks prior to occupancy that no other construction firm in the Bay Area could have handled such a task and pulled it off successfully. For well over ten years I have had the opportunity to work with Alten Construction on projects from modernizations to complex alteration.

Communication was excellent both ahead of the works at pre-planning stage.

Working with Arden Construction on this project was a pleasure from start to finish, both in terms of the team and the end product. Lee Hands the Site Manager was particularly accommodating and easy to work with, especially given the inherent problems a fire station can throw at contractors.
