Ground Run-Up Enclosure - Memphis International Airport, TN
Pond provided engineering services which included overall project management, feasibility analysis and construction document preparation for this project. The Tennessee Air National Guard (TNANG) relocated their entire base from the north end of the Memphis International Airport to the southeast corner of the airport, and underwent an equipment change from the C-141 to the C-5 aircraft. Memphis-Shelby County Airport Authority (MSCAA) allows engine run-ups only in certain designated locations at certain designated times which are far from the TNANG site and therefore would have significant mission impact. Thus, TNANG requested a study be accomplished to assess the feasibility of providing a Ground Run-up Enclosure (GRE) on the new TNANG apron, and if feasible, prepare the construction documents.
For the initial feasibility study, an in-depth technical memorandum was prepared. Pond collected C-5 engine compressor setting data for engine run-ups, as well as test frequency from maintenance personnel. Sound data was then passed to GRE manufacturers, who then prepared a concept design including acoustical performance, geometry, utility requirements and costs. The GRE manufacturer-prepared acoustic data was then input into a previously prepared noise model for MSCAA to ensure the GRE would perform within the FAA Approved Part 150 Study, specifically, the 65 DNL contour, which was within proximity of existing residences.
The proposed GRE geometry was evaluated with respect to impact on existing site conditions. Foundations are significant and required relocation of sanitary sewer, apron drainage and other utilities. Additionally, the GRE had to be sited to ensure required wing-tip clearances for adjacent taxing aircraft. Additional items requiring coordination included FAA Part 77 clearances, airfield navaid interference check and tower line-of-site check.
The technical recommendation was reviewed by MSCAA, Air National Guard and FAA personnel for compliance with airport facilities, operations, construction and mission objectives and requirements. Construction document (CD) preparation incorporated the findings of the feasibility study. The CDs addressed utility relocation, grading, drainage, utilities, airfield pavements and a flexible footprint such that the project could be competitively bid in accordance with federal procurement policy. Acoustical performance was specified such that the final product would perform as required. Specifications required the contractor to prove the system performs as required through specific test procedures and documentation, prior to acceptance of the project as complete. The project was awarded within budget, construction is now complete, and the facility is in use.
