Multitasking

Dear Readers,

Recently, I came across a humorous meme that serves as an eye-opener for completing result-oriented tasks. At first glance, the image looks impressive, as it seems to show someone multitasking effectively and saving time. However, a closer look reveals that this approach is completely impractical, resulting in zero progress despite being fully occupied. In reality, it conveys 0% progress and 100% occupation.

He can’t use his laptop because he’s holding a drink.

He can’t drink because he has a cigar in his mouth.

He can’t smoke his cigar because both hands are occupied.

This is a Masterpiece of multitasking, where absolutely nothing gets done.

…..where someone is 100% occupied but 0% productive?

In your professional life, you may reach a point where you are either an employee or a manager. The first thing you need to understand is the difference between multi-skilling and multi-tasking.

When you concentrate fully on one task at a time, you are more likely to complete it successfully and maintain high quality. In contrast, attempting to juggle multiple tasks simultaneously often results in none of them being finished well or providing a sense of fulfillment.

In conclusion, multi-skilling is more crucial than multitasking. To effectively perform multitasking, one must have a range of skills.

Bolt Grades

Dear Readers,

In construction engineering, bolts are frequently used. The grades of bolts typically range from 4.6 to 12.9. These are also referred to as Ordinary bolts (Commercial Grade), HT bolts (High Tension), and HSFG bolts (High Strength Friction Grip).

The bolt designation system consists of two numbers. The first number indicates the bolt's ultimate tensile strength, which can be 400 MPa, 800 MPa, or 1200 MPa. The second number signifies the point at which the bolt will permanently stretch. Specifically, a grade 4.6 bolt will permanently stretch at 60% of its ultimate tensile strength, a grade 8.8 bolt at 80%, and a grade 12.9 bolt at 90%.

Technically, it can be quoted that the first number is the tensile strength of the bolt material (N² )/100. The second number is = 1/100. (the ratio of the Proof (or Yield ) stress and the Tensile strength expressed as a percentage = 100.[Yield (Proof stress) /Tensile strength] /100

For example, the tensile and proof strength of the steel for an 8.8 bolt is therefore calculated as follows

Tensile strength = 8 X 100 N/mm² = 800 N/mm² and Proof strength = 0.8*800 * 100 /100 = 640 N/mm² (generally speaking 80% of 800N/mm2)

The lowest grade is 4.6, commonly known as commercial grade. Next comes grade 8.8, known as structural grade, and finally, the highest grade is 12.9, known as HT / HSFG bolt.

Available grades of bolts are 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9 & 12.9

Cost of Man Day

 Dear Readers,

Let us discuss how to calculate the Man Day cost. MD refers Man Day; it is a unit of measurement for workforce.

Eight-Hour working is called One shift and one person working one shift (8 Hours) is called one man day. 

If the work gang comprises 10 workmen and working one shift is equal to 10 MD and if the gang works 6 days then it is 60MD.

In construction industry over time has existed. It is subject to the nature of job. Normally 3 Hours overtime is regular in all sites. However, benefits will not be applicable on overtime wages.

During MD rate calculations terminal benefits are subject to the duration and local site environment

MD rate arrives from

             ABW (Average Basic Wages)

             Over Time Wages 

             PF & Admin. Charges of employer portion

             Terminal benefits 

There are several laws in India which govern the maximum overtime hours allowed in India and also provide for an overtime calculation formula in India. Based on the industry one works for; the overtime payment rules vary. Some workplaces may be governed by the central laws while the other might be a subject of state laws.
