GROUND FLOOR SLAB

Concrete Casting of Ground Floor Slab: The ground floor slab (along with tie-beams) were casted with M20 Grade concrete on April 14th, 2017. It took more than 10 hours and required 52 workers. We used 24 Metric Tonnes of Ultratech Cement, 900 CFT of Sand and 1800 CFT of stone aggregates. M25 Grade for Foundation, and M20 Grade for columns/slabs provide ideal strength to the Superstructure.

 

Ground Floor Slab Reinforcement: The steel reinforcements for the slab and tie-beams of Ground Floor were made in accordance with the Structural Design. Around 3.5 tonnes of steel was used for making the slab, 4 tonnes for making the tie-beams, another 4.5 tonnes for making columns, and around 0.6 tonne for the Elevator wall and staircase.

PILE CAPS AND PLINTH

Breaking of  Pile Tops: The concrete of every pile top was broken down upto a depth of 1 metre. This exposed the 6 Steel bars which were later connected to the reinforcements of pile caps. This process required a lot of effort and skill, and was done using a chisel to avoid any crack in the pile. We waited for atleast 28 days after the pile was casted (constructed), so that it gained its full strength before its top portion was broken.

 

Rod Binding & Making of Pile-Cap Reinforcements: After the top portion of the pile-caps were broken, and a PCC of 100mm was casted, pile-cap reinforcements were made carefully on the PCC. Proper measurement was taken to ensure the size was as per the structural design, and that all the reinforcements were at the same horizontal level.

 

Concrete Casting of Pile-Caps: Concrete casting of Pile-Caps was done as per M20 standard. The ratio of cement: sand: aggregate (stonechips) in M20 is 1:1.5:3. For a residential building this is the finest standard above the piles till plinth level.

DEEP PILE FOUNDATION

Rod Binding & Making of Pile Reinforcements – 16 mm diameter Steel Bars were used for vertical support, and 8 mm diameter Steel Bars were used as stirrups. The total length of the reinforcement was 15-17 metres (50-56 Feet)

 

Boring of Ground and Flushing with Bentonite Water Solution: The ground was bored till depth of 15-17 metres depending on the length of reinforcement. Simultaneously the bore was flushed with Bentonite Water Solution to strengthen the capacity of soil.

 

Installation of Pile Reinforcements: The first pile reinforcement to be installed was 12 metres in length which was held from top. the Steel bars had 150 mm ‘L’ shape bent at the bottom. The second pile reinforcement (of length 4m-6m) was installed on the longer reinforcement with a lap-length of 800 mm. The result was a reinforcement of exactly 15.05 -17.05 metres (15 – 17 metres approx).

 

Concrete Casting of Piles: Concrete casting was done as per M25 standard. The ratio of cement: sand: aggregate (stonechips) in M25 1:1:2. M25 is considered to be the finest standard for construction of piles for buildings which have height till 30 metres, providing an extremely strong foundation and extra longevity for the building.

SOIL TEST FOR FOUNDATION

Proper physical and chemical tests were done on the soil of the plot. The structural design of the building was made in accordance with the result of the soil test.
