"This letter is sent to provide a recommendation for HR Allen and to provide a brief summary of their involvement with two middle school projects for which UWPD Architecture was the architect and HR Allen was the electrical contractor.  
HR Allen worked as the electrical contractor for Lugoff-Elgin Middle School and Camden Middle School, both for the Kershaw County School District.  Each contract was structured as a single prime contractor, with HR Allen working underneath two different general contractors.  The two schools were largely identical, both being next generation prototypes form previously completed projects in Horry County.  HR Allen’s field personnel and office team conducted themselves in a very professional manner, strove to understand the project goals, and subsequently achieve those goals.  Overall, we were very pleased with their performance and would gladly recommend them for consideration in your current building program."
