Testing on construction site may result in noise, vibrations Published Aug. 7, 2014 By 79th Medical Wing Public Affairs JOINT BASE ANDREWS, Maryland -- The first phase of construction for the new Malcolm Grow Medical Clinics and Surgery Center is steadily progressing. The Military Construction contractor has completed support beam drilling operations for the future-parking garage that will be located adjacent to Building 1075. Workers will begin testing their work on Aug. 13-14. The tests may result in an audible "bang" as a weight is dropped into the shaft. Staff and patients may experience vibrations and noise. The tests do not have a firm schedule and will be performed throughout the workday on both days until completed. For more information, contact Capt. Derek Findlay at (240) 612-1159.
