Storage Igloo

Summary (CONUS)

Air Force has adopted USACE's standard design STD 421-80-08 for CONUS Storage Igloos. The MSM Box-Type Standard 421-80-08 replaces the previous Munitions Storage Magazine (14 feet ceiling height) as designed for Hill AFB. The new series updates the drawings to meet current AEC CAD standards, and features improved plan readability, constructability, and corrects omissions within the construction drawings. Another key element performed during the revision was the incorporation of lessons learned (see Appendix of Design Narrative) from previous MSM projects at various user organizations. In addition to the drawings, a conventional structural load analysis was performed to identify some key loading limits, which will assist the designer during the site-adaption process.
