Under reinforced foundation
(OP)
Hi,
I have a problem..A contractor has not followed the structural plans and has cast 42 pad footings and columns.Now according to the load that the building will carry some of the foundations are found to be in adequate. Apart from demolishing and cast again, is there any method to remedy this?. Intermediate columns cannot be placed to reduce the loads spread.
Secondly, the Contractor should have placed ground beams. but the latter did not do that and has cast a 6m high column. According to the loading and height of the column, the reinforcement which the contractor has placed is not enough. Can the bars be dowel to place the ground beam?

RE: Under reinforced foundation
The method that i can suggest to you is to retroffit ta affected structural elements.
One type of retrofitting is by FRP wrap.And another is by enlargement..But since you need to cast ground beams I suggest that you enlarge those members in such a way that you can place the ground beams reinforcment inside the additional column reinforcement.
RE: Under reinforced foundation
If i enlarge the pad footings, I will have to dowel reinforcement into the existing one. Will the foundation be strong enough to support all the loads?

Or, at least get payment up front to do his engineering work, or have him submit engineering to you for you and the owners approval.
for the life of me, I dont understand why contractors cannot read and follow directions. I understand mistakes will be made, but 42 times?

Doesn't fit all situations, but it can be a great trick. Remember: Your starter bars need to be able to develop or be spliced before the topping is cast; Then you may have a bundled bar condition to check.
DO NOT LET SOMEONE ELSE'S PROBLEM BECOME YOUR LIABILITY. Yes, I am yelling as a point of fact. *smiles*
RE: Under reinforced foundation
But Smitash regarding with your question if that would be strong enough to carry the loads, of course it depends upon on how you do your analysis.Note that you will have now a new embedment depth which one parameter essential in the design.
