To Whom It May Concern:

As the Director of Maintenance and Facilities for Placentia Yorba Linda Unified School District it has been my privilege to have Chris Knowland and Knowland Construction Services as a part of our school construction team.

From 2002 until currently, Knowland Construction Services (KCS) has provided DSA Inspection services and project support for Placentia Yorba Linda Unified School District on more than $400 million of complex construction projects including a new middle school, a comprehensive high school, a performing arts center, stadiums, aquatic center and numerous modernizations.

The staff at Knowland Construction Services has in-depth knowledge of construction methods and materials, scheduling experience and understanding, look-ahead problem solving and a team oriented approach to project performance. All of these characteristics are born by their lengthy industry experience that comes in the form of ‘ hands on’ field experience and a field level problem solving approach. I have found the rare inspection team that understands the overall goals of the district, along with their administrative code responsibilities, that provides the owner with a comprehensive approach to school construction.

KCS has proven to be a vital asset to the District in ensuring our projects were delivered according to the plans and specifications, as well as acting as the districts ‘in the field’ advocate in monitoring coordination between contractors, evaluating change orders, construct-ability, schedule concerns, and design issues. Knowland Construction Services communicates well with licensed professionals and contractors in anticipating issues and they work with the construction team to provide a resolution that benefits the project. It is rare to find a company that combines a comprehensive level of field experience and a project orientation in the owner’s interest. Knowland Construction Services is that rare combination.


It is my opinion that school construction requires a total team approach along with in-depth construction knowledge and experience as its foundation and core competency. Chris Knowland and Knowland Construction Services have proven this to be true and have proven their value to the district. Therefore it is without hesitation that I recommend Chris Knowland and his Knowland Construction Services team for consideration as a member of your construction project team.
