"Sauer, Inc. contracted with HR Allen on Starship 11000 Repair Project at Ft. Jackson, SC, contract # W912HN-07-D-0060 DO #004 for the electrical work.  The overall contract value of this project was approximately $68 M and we had two subcontracts with HR Allen which included work on a temporary ‘swing space’ facility ($2.9M) and the building 11000 renovation($2.4M), both of which occurred over a 3 year period.  
HR Allen did an excellent job on this very challenging project.  They performed their scope of work in a timely and effective manner, and manned up to help us complete the temporary site on time and the building 11000 work two months early per the Owner’s request.  We relied heavily on HR Allen to get the job done and they did an outstanding job in all respects.  I strongly recommend this firm to other companies considering HR Allen for contracted work."
