Topic: Cement Slab as roof for elevation

Hi Experts,

We have constructed house through contractor and for top floor staircase its open to sky and their is elevation wall built on four sides 7 feet height and its 4 inch thick wall. 

Now to cover the roof contractor has put 2.5 inch concrete slabs of 2 feet width and 7.5 length and in that 1 feet will be projected outside and total he used 6 no's 

They are poured on ground using the steel reinforcement of 12mm rods and 8 mm rods.

 12 MM 5 No's and 8 MM for every 5 inch and poured concrete and the total thickness of that slabs is 2.5 inch and after 7 days he lifted and placed them on the walls.

Now my doubt is will the wall hold that weight and not collapse after some time. As per him he says it will safely hold as their wont be any other weight as we are not going to climb it. Not sure, but  i am getting paranoid when ever i look at that elevation roof.

Please help me whether its correct that 4 inch walls on four sides will hold the weight and not give up after sometime and break the entire elevation.

Regards
Neel

Hi Gupta Sir,

Small Correction of the above mentioned details

Two sides of the walls are 6.5 Feet they are on the Roof but the other two sides are on the stairs landing so they are coming to 10 feet.

Slab size is 7.5 feet in Length and width is 1.5 feet.

Rest all remains same sir.

I am very sorry for the mistake in giving information.

Regards
Neel

Dear Neel,
        In my opinion the size of slab is small and weight is distributed on four sides so do not worry. In future when you want to do any construction than it is advisable to take proper design from structural engineer, the small money spent on design will be beneficial in the long run.

Dear Neel,

The concrete construction at 1WTC found at the Twin Towers Site on 16 acres (64,750 square meters) south of Manhattan, New York, began in April 2006.
 The excavation of the 80-foot (24.38-meter) ) Is located on a slab of the original twin towers. The slab separates the excavation from an existing subway line. The crews worked around the slab and about 300,000 travelers using the metro system daily. Collavino moved an S 58 SX from Schwing to the work site in the summer of 2007 to begin massive spills of slabs ranging from 12 to 13 inches (0.30 and 0.33 meters) thick and core walls and columns 6.5 feet (1.98 meters) Of thick. By pumping from the street level, the truck-mounted boom pump has a range of up to 175 feet (53.54 meters) horizontally while meeting all discharge schedules with a capacity of 213 cubic yards (162.82 cubic yards) per hour. The pump's Super X brackets, with a 29 '2 "front end, keep the footprint to the minimum level in crowded New York City downtown.

por hora. Los soportes Super X de la bomba, con una distribución frontal of 29' 2?, mantienen la huella al nivel mínimo en el centro de la Ciudad de Nueva York abarrotada de gente.
