Estimating Concrete Volume ??

Question

Hi there, i'm doing a coursework on estimation of quantities and concrete. Included are plans and elevations (with not many measurements) of a residential house. I'm a bit confused regarding Question 2, which has asked us to determine the volume of concrete needed to build all the concrete elements of the house.

The length and width of the house is 13.3m and 15.2m

the Height of the house from ground to roof is 8.805 m

There is also a figure giving the slab level SSL 30 -250 (not sure what this is)

I think we are suppose to just assume the depth of concrete needed, as it has not been stated on the plans. What would be a realistic figure? What do I have to take in account? Footings, slabs?

I understand the formula used to work out the volume of concrete is:

Length x Width x Depth

But, In GB do we order concrete in cubic meters or cubic yards? I just want to make sure I give my answer using the correct unit.


thanks for any help in advance...

You are required to give a breakdown of materials required for the volume of concrete required in any of the houses of your choice shown in the drawings, making any suitable assumptions wherever required. Please follow the following procedure.1.Study the drawings provided carefully and identify the slabs, beams, columns etc that will be constructed out of concrete.2.Determine the volume of concrete for all these elements (Note assume the concrete will be of same type though in reality they could be different).------------------------------...

thanks for all the replies so far. ive uploaded the images of the plans and elevations, if it helps?.

Answer 1

Cubic metres is the GB version of unit system and the conversion of it is -------> The basic unit of length adopted under the Système International d'Unités (approximately 1.094 yards)

Since the question has m in it the sure answer logically is in metres so yeah u need to give answer in cubic meter. I am not sure how to work out ur answer but since u have the formula try finding the volume. Volume = length * breadth * height so 13.3 * 15.2* 8.805 shud give u volume and volume is depth as depth means Extent downward or backward or inward so just chk out if I've worked out logically I hope this helps u.
or else go to wikipedia.com

Answer 2

First thing I'd do, is submit a Fire Insurance Plan to the Local Building Department . That way You can get a Fire Permit. Then Burn the Plans to someone whom can wok you threw it. It Gets a Little Tricky, Cuz yall have to pay a Little Tension to What Yer doin, I Convert it by Cubic Inches, to Yards, Works better for Footings and Piers, Usually Dead Nuts Right On, Most of the time. Besides that, Yer numbers come out to about sixteen hundred and thirtyYards, Missing Something .. Seems Fireprufe enough, Only Problem is How many Diamond Blades, and Jack-Hammers are you going to go through, trying to carve the rooms out ??

I'm a builder and how i work it out is like this 13.3 twice is 26,6...15.2 twice is30.4 add together ..that's57 metres long all round the footing ..57times 3.33 is approx 190feet ..the trench should be 1metre deep by 600wide..as i trench fill with concrete....1 metre is just over 3 feet and 600 is approx 2 feet ..then 3 by 2 by 190 is 1140..there are 35 cubic feet in one cubic metre ..divide1140by35 that's32.57cubic metres needed to fill footings ...now the floor slab13.3times15.4 is just over202 square metres..times 11.1 is 2242.2 square feet ..note ..a metre is 11.1 square feet ..allowing 100mm...or 4 inches divided in a foot ...4 into 12 is 3 ...2242 divided by 3 is 747... divided by 35 the amount of cubic feet in a metre..the answer is 21.34 cubic metres to do the over site ..hope you understand this

Answer 4

SSL is Structural slab level. The figure of 250 is probably the slab thickness. But I would ned to see the drawings to be 100% sure. As long as you state that you have made this assumption and stated your reasons for doing so you should be OK.

Answer 5

your length and width are given. to find depth, you may be able to interpret the slab level as the depth, or the overall height may be needed to calculate the depth. check your course books or the internet to determine. additionally you should consider purchasing 10-20% extra than the calculated volume because if you run out before the job is complete, you will waste time and money trying to buy more.

Answer 6

Usually cubic metres (note UK spelling), but yards is acceptable as long as you specify.
