2000 saw the rapid expansion by the Pennsylvania and Ohio Air National Guard and US Navy Seebees, this included the addition of constructed 15 force-protection projects, high-security entrance points, kennels, and aircraft maintenance facilities, each made more difficult by the concrete-like bedrock which makes up the deserts of Qatar. The work plan had engineers pouring of concrete, moving of desert rock, which took more effort to move compared with the sand that makes up most of the deserts in the region, and erecting 50,000 pounds of steel. The work also included building 32 Scud bunkers, placing five towers, building of blast wall, constructing a mile of road and digging a mile of trenching. Heat was the common theme throughout the deployment. Doors had to remain closed or temperatures could rise high enough inside to trigger fire-suppression sprinklers; pools had to be chilled before entering. As temperatures soared through the 100s each day, guardsmen devised ways to work through the desert menace. These included 4 a.m. start times and air-conditioned shelters at each job site. In late 2002 a second wave of engineering projects expanded the base further adding some basic comforts to the previously barren camp such as a small swimming pool, trailers replacing tents for the dining facility and the addition of a larger post office to handle the influx of mail that came with the increased number of troops. Prior to the late 2002 build up troops stationed at Camp Snoopy were bused an hour each way to Al Udeid Air Base for basic recreation and exchange use.
