The Department of the Army, Army Materiel Command, has a requirement for Grounds Maintenance Services at the Osan Air Base, South Korea.

N/A

• Osan Air Base landscape does not only contain flat grounds, but it also contains hills in many areas of the base, which needs to be considered in planning task performance methods. The base rests on the mid-western coastline facing the Yellow Sea. As such it is subjected to various weather conditions that can range from heavy sea effect, snows in the winter to persistent monsoon rain in the summer. As a result, the growing and mowing season runs for eight months from March through October. The four non-mowing months are occupied mostly with leaves and pine needles collection and other debris control potentially resulting with indefinite task orders. Osan AB consists of improved grounds, semi-improved grounds, airfield semi-improved grounds consisting of Bird Area Strike Hazard (BASH) areas, munitions storage areas (MSA), and unimproved grounds. Further, the airfield contains a complex of mainly BASH areas, semi-improved grounds, and minor portion of improved grounds. Fence lines identified shall be trimmed to prevent vegetation growth in the fence, including removal of vegetation/vines growing up the links of the fence. All areas shall be trimmed concurrent with mowing
