In an earlier post, we had discussed the cost estimation for different construction activity. Now, we are going to see the rate analysis for plastering.
Before analysis, understand the general aspects of Rate analysis of civil works.
The following points have to be considered while analyzing the rate.
Lets us assume that we need workout rate analysis for 10 Square metre area of inner plastering work.
From the mortar mix ratio (as per IS standard), the required mortar ratio is 1:3 and thickness is 15mm
STEP 1 – Mortar Mix Material Calculation
We have detailed the calculation in our plastering work calculation post.
So we need Cement – 1.67 Bags and Sand – 0.174 m3.
STEP 2 – Required Manpower
From our Labour output per day assumption
For 10 sq.m of Plastering, we need
Description | Unit | Qty | Rate | Amount |
MATERIALS | ||||
Cement | Bags | 1.63 | 350 | 571 |
Sand | m3 | 0.174 | 1500 | 261 |
MANPOWER | ||||
Supervision | Day | 0.05 | 800 | 40 |
Mason | Day | 1 | 700 | 210 |
Helper | Day | 1.2 | 600 | 720 |
Waterman | Day | 0.1 | 450 | 45 |
Subtotal | 2,337 | |||
Tools & Tackles | 1% | 23 | ||
Power Consumption | 2.50% | 58 | ||
Adding Sundries & Contingencies percentage | 3% | 70 | ||
Adding Overhead & Contractor profit percentage | 10% | 234 | ||
Total | 2722 | |||
Price per Square metre | 272 |
The required manpower will differ based on the nature of the work such as plastering thickness, working height etc.
