This requirement is a follow-on award to Tetra Tech/Mead & Hunt JV. The requirement was previously negotiated and awarded viacontract/task order W911YN19F0059. That award included Type A and B services forthe design of the Repair BE Admin Shop Bldg. 4210-4211. Type A services included thebasis of design (specifically the design intent), the development of the project concept,and associated site investigations. The Type B services included the design narrativeand the development of the construction documents.

Because Tetra Tech/ Mead & Hunt JV designed and certified the drawings and specifications and is liable for the quality of their design, it is economical and efficient to award the Type C services as a sole source follow-on contract. There is tremendous performance and liability risk associated with another A-E firm taking over the Type C services for a project that was designed by a different firm. Having the original designer, Tetra Tech/ Mead & Hunt JV, on contract to perform the construction phase services is necessary for the Government to ensure responsibility for their design.
