Folks,
I have the following query.
I have the following openings for patio doors.
1. 2.7 Metres
2. 2.4 Metres
3. 3.6 Metres.
In the case of no 1. (2.7 M wide span) it has the inner leaf of blocks on the flat therefore this lintel will be 225mm wide. In the case of the outer leaf it will be a 100mm wide lintel. All that is over this is approx 5 courses of block and then the roof. Will a prestressed concrete lintel do this job.
No 2 is a patio door on a gable. Again a 225mm wall inside then a 225 wide prestressed lintel then hollow core flooring. outside leaf is 100mm wall with a 100mm prestressed concrete lintel. above this is approx 5 courses of block then roof. Will a prestressed concrete lintel do this job??
No 3. As per no 1, just a wider opening. Will a prestressed lintel do this job.
My engineer has put in catnic lintels in these places, however they are over 2500 euro. Just wondering is there a cheaper method of doing this.
I already made numerous changes to drawings so I dont want to be annoying my Engineer yet again on this one.
Any input would be appreciated.
Thanks.
