How to calculate mason, labor for brick masonry construction with help of thumb rule

In this construction video tutorial, you will learn how to compute the mason as well as labor toward a 1st class brick masonry construction with the help of thumb rule.

A thumb rule refers to a principle having extensive application that is not projected to be exactly perfect or authentic for each situation. This method can be easily applied for making approx calculation or recollecting some value, or for making some determination.

It should be noted that the quantity of required labor will be gradually increased from ground floor to first floor to second floor etc.

Thumb rule is a constant value that is taken from the earlier construction work i.e. how much volume is covered by the labors employed in earlier projects. All the volumes are summed up to find out the average volume.

In ground floor, first floor and second floor, the volume of total area is taken as 150 m3

Ground floor :-

Mason = Volume x thumb rule (for mason) = 150 x 0.71 = 107 numbers
Now, suppose the charge for one mason = 1100 rupees
So, the cost for mason will be 107 x 1100 = 117, 700 rupees

Labor = 150 x 1.18 (thumb rule for labor) = 177 numbers
Suppose, one labor charge 800 rupees
Therefore, cost of labor = 177 x 800 = 141,600 rupees

Similar process should be followed for 1st floor and 2nd floor. Here, the value of thumb rule will be increased as the steps are increase.

To learn the calculation for 1st and 2nd floor, watch the following construction video tutorial.

Checklist of Concrete Formwork at Construction Site throughout Concreting and Striking

Concrete formwork stands for a temporary supporting structure for concrete. It is arranged at the job site to retain the concrete in perfect position and shape unless it becomes solidified.

Ensure that formwork should be done prior to start of concreting work, throughout concreting and after elimination of formwork. Concrete formwork contains both quality and safety threats. If the formwork is improper for the concrete and work is accomplished at height, safety issue may occur.

If the formwork is imperfectly organized and does not have good resistance capacity against leak, the quality of concrete may hamper. If the concrete formwork is stored sufficiently, the cost of the project is reduced significantly.

Checklist of concrete formwork in construction site:

Formwork Checklist for Walls:

1. Make sure lateral bracings rigidly supports the forms at all points of support.
2. Layout (stop end) braced to withstand vertical and lateral loads.
3. Form panels are sufficiently braced and attached with each other.
4. Formwork corners shall be adequately attached so that leakage, bulging and spreading of concrete do not occur.
5. Make sure there is adequate length for wall ties as well as necessary strength and spacing as necessary.

6. Verify wales to maintain proper spacing and joints and they should be staggered from one tier to the next.
7. In double member wales, one member remains continuous over the location of form ties.
8. Wall ties and bolts are tightened properly.
9. In case of double member, wales are utilized an

10. Verify that sufficient lap exists among forms and previously cast concrete.
11. Make sure that there is no grout leakage at joints among panels and joints connecting old concrete and panels over them.
12. Examine the provision of resistance against uplift for sloping faces of concrete formwork.

13. Make sure that the installation of wall forms and placement of concrete should be done at the construction site in the presence of an experienced supervisor.
