3.3 Rule-of-Thumb Calculations. Every HVAC designer needs some handy empirical data for use in approximating loads and equipment sizes during the early conceptual stages of the design process. These are typically square feet per ton for cooling, Btu per square foot for heating, and cubic feet per minute per square foot for air-handling equipment.
steel weight is building height. A rough approximation for steel weight per square foot in a braced building using steel with Fy = 50 ksi is: Wt(psf) = stories/3 + 7 A three-story building would have a steel weight in the range of 8 psf and a 27-story building would require 16 psf. Certainly, this relationship is an over simplification. Yet, it provides a value,
HVAC Rule of Thumb Calc-3 http://www.engproguides Table 1: This table shows a list of the popular unit conversions applicable for this calculator. 1 Btu/h = 8.33 x10 -5 tons 1 ton = 12,000 Btu/h
How many Btu per square foot for air conditioning - Answers. 600 spf A good general rule of thumb is 20 BTU per square foot. So, a 200 sf room would require a 4000 BTU ac unit.
700 lb. of sand and 3 to 4 bags of mortar per ton. Brick. Approx. 7 bags of mortar per 1000 brick (143 brick per bag) Approx. 1 ton sand per 1000 brick figure brick 7 per sq. ft. of wall area (allows for waste) 1-1/2 brick per running foot on wall 4.625 courses of brick per foot of wall height 5 brick per sq. ft. for paving, hearths (laid flat- solid brick)
16/08/2005· Dead loads are presumed at up to fifteen pounds per sq ft and live loads at thirty to fifty depending on room intended use, plus 25 to 110/ft for live loads on roof, depending on snow zones. A foundation needs to handle not only the dead load of what the buiolding itself weighs, but it

The building type is used to provide the appropriate square foot per ton value and airflow (CFM) per square foot value. Apartment, Mid/High Rise: Description: This building type can be used for apartments or condominiums that are larger than single family homes or multi-family dwellings. An apartment building under this type can be a high rise
Conversely, the steel quantity (pounds) per square foot of the building area could be checked to see if it falls within the thumb rule range for a building. The estimator may perform the actual quantity take-off for structural steel framing and divide the total pounds by the Gross area, to check pound per square foot validity of Structural Steel quantity. Any value below 8 pounds per square,
Rule of Thumb Figures; Block. 2-1/4 bags mortar per 100 block (40 block per bag) 800 lb. of sand per 100 block 1.25 block per sq. ft. of wall area 75% of length of wall gives umber of block per course take height of wall (in feet) times 1.5 for number of courses Stone. 700 lb. of sand and 3 to 4 bags of mortar per ton. Brick. Approx. 7 bags of mortar per 1000 brick (143 brick per bag) Approx,
4. Thumb Rules For Shuttering Work. Shuttering costs are taken as 15-18% of the total construction of the building.Shuttering work is done to bring the concrete in Shape.The Thumb rule to estimate the shuttering required is 6 times the quantity of concrete or 2.4 times of the Plinth area.. For example, the concrete quantity is 0.5m 3, then. Area of Shuttering is 0.5 x 6 = 3m 2
28/02/2008· 29/02/2008· Would anyone be able to point me to a source where I can find rule of thumbs for watts per square foot, based on certain building types. I need information for when we are in the Schematic Design stage of design, I can approximate the size of
