WEEK- 4​ Oct - 12
QUALITY CONTROL
Quality measures that we observed:
​
-
To ensure the highest quality of concrete, they have hired a consultancy called ‘Nova Engineering and Environmental, Atlanta’ for performing cylinder test on Concrete.
​
-
As stairs act as an ‘Emergency Exit’ at the time of fire hazard, they are taking extreme cautions to make the stair walls fire proof. The quality in the work is maintained in such a way that the stair walls can withstand a continuous fire for 3 hours without failing. To achieve that, they are using a material called ‘DensGlass – A fiberglass mat gypsum sheet.

​
​
​
-
Quality on MEP work: Every intersection of pipeline and floor at each level of building is provided with foam insulation to improve the durability of plumbing system.
​
-
To achieve superior quality of concrete finishing, each part of formwork is applied with oil coating. This will help to achieve :
-
Honeycomb free concreting.
-
Easy removal of formwork.
-
Smooth exterior surface.
-
Some properties of DensGlass:
-
Superior moisture and mold resistance.
-
A rigid substrate for a wide variety of air or water-resistive barrier systems.
-
Flexibility with construction schedules despite of bad weather.
