How to estimate the number of studs for wall framing?

Not all studs are created equal. For this reason, most estimators will add an additional 10 percent to the stud count to make up for any waste material, such as split or warped studs. For stud spacing, a good rule of thumb is 16 inches on center for exterior walls and 24 inches on center for interior non-load-bearing walls.

How is the thumb rule used in cost estimator?

The cost estimator may group the available thumb rule items according to the CSI (Construction Specifications Institute) divisions or other preferred WBS (Work Breakdown Structure), for easy understanding and quick reference.

Which is the average cost of construting a Resedential ternament?

Thumb rule for calculation; Average cost of construting a resedential ternament region may very from Rs. 800/Sq. ft. – Rs. 2,500/Sq. ft. depending open quality of material. This cost includes entire cost of labour and material from excavation to fitting of doors and window with eletrical wiring and plumbing cost.

Which is the best method for estimating the cost of equipment?

When preparing preliminary estimates, two methods for estimating the cost of equipment are the Rule of Six-tenthsand the use of cost indices to adjust historic costs to current prices. Each will be discussed and a single example will be offered to demonstrate the use of both. The Rule of Six-tenths

How big should the studs be on a 2×4?

Remember: The regular OC stud spacing is 16, 19.2 or 24 inches. (OC spacing means measuring the distance between the centers of two adjacent studs .) If you would like to use the price section of our 2×4 calculator, you’ll also need to know: The estimated percentage of wastage.

What do you need to know about stud Count?

The equation is as follows: OC (on-center) spacing – the spacing between the center of one stud, and the center of the next stud. Remember, don’t measure the OC from the end of each stud! Why do we need to add one more stud? The simple division allows us to count only the studs in the middle of the frame and a single end stud.

Which is the best rule of thumb for estimating cost?

A rule of thumb developed over the years known as the rule of six-tenthsgives very satisfactory results when only an approximate cost within plus or minus 20% is required. An exhaustive search in conjunction with the development of this course left this author with no indication of any single individual who developed this concept.
