Pier block

Follow the engineers drawings and use building regs advice to what is needed. But I have done these before and normally a small foundation underneath the pier to that the load. Factors are how big the steel is to take the load and what the pier will be sitting on.

As regards engineer requirement he or she it telling you we need to determine what is under the tiles .(i assume the floor is concrete).So by removing tiles we can now see if we have a good base if not we can build a base (concert)and that's the reason to make sure you have a solid foundation

Yes, we've carried out similar work before. Once the tiles are removed, we would need to inspect the existing floor construction and foundations to ensure they are suitable for supporting the new block pier and steel beam load. Depending on what is found underneath, it may be necessary to excavate a small area and install a suitable concrete foundation before building the pier in accordance with the structural engineer's drawings. If you can share the drawings and a few photos of the area, I'd be happy to take a look and give you a better idea of what's involved. Thanks www.Melodyconstruction.co.uk

If you're supporting a load barring steal i would advise to dig out the floor 150mm around the pillar and put a 225mm pad footing

Hello. Yes, this is a fairly common structural alteration. Once the floor tiles are removed, the next step is usually to expose the existing concrete slab and excavate beneath it to the depth and size specified by the structural engineer. Depending on the engineer's design and ground conditions, a reinforced concrete pad foundation may be required before the masonry pier is built. Once the concrete has achieved sufficient strength, the pier is constructed using the specified engineering bricks or concrete blocks, ensuring it is correctly bonded and level to receive the steel beam. Building Control will normally inspect the foundation before it is concreted and may also inspect the completed pier before the beam is installed. The exact sequence depends on the engineer's drawings and site conditions. I hope this helps.
