Main support beam replacement in basement
Upon renovating our basement we discovered that previous home owner had cut a 3 foot section out of the main support beam of our house to give more headroom for a doorway. They only used 6x6 wood posts to support the beam on either side of the cut. These posts are just resting on the cement ground (no footings). Obviously we need to have the beam replaced and yes, we have hired a structural engineer to give my contractor the specs required.
We are going to be installing a new steel i-beam with two steel posts to support it (with proper footings). I have two questions:
- how long does it take for the footings to cure?
- our basement is only 6'7" high and the new beam will be running the length of the house basically down the centre. To get as much headroom as possible, we'd like to have the new beam 'recessed' into the ceiling or 'flush mounted'. How do they do this? I know it will be much more expensive, but is the cost astronomical?
