Abstract: A ground site for a building is prepared for construction of a portland cement concrete slab-on-grade (PCC SoG). Using a computerized weather application, weather conditions for a geographic locale that includes the ground site are monitored to identify a window-of-time during which the weather application indicates there is a less than 50% chance of precipitation at the geographic locale. The surface of the ground site is proof rolled during the window-of-time. Using concrete emplacement equipment during the window-of-time and only after the ground site passes proof rolling, wet concrete is emplaced on the ground site to a nominal thickness that does not exceed 7 inches and that is at least one inch less than a PCC SoG design for the ground site having a design thickness based on design guidelines set forth by the American Concrete Institute. Emplacing must be completed with at least 4 hours remaining in the window-of-time.

Abstract: A fingerless mitten is provided for allowing all the fingers of a hand to reside within a single defined cavity to maximize the benefits of body heat and for allowing all the fingers of the hand to be easily freed from the defined cavity while the mitten remains on the hand. A sleeve of material has coaxially aligned open ends such that one's hand can enter a first open end of the sleeve and pass freely through a second open end of the sleeve. Flap means are provided in cooperation with longitudinal portions of the sleeve and a portion of the second open end of the sleeve, whereby the single defined cavity is formed.
