Lift Hall call button and rebars

[LewisLiew]

Looking for opinion:

Hall call button for a lift is 300(h)x150(w) and it located on junction of rc wall and rc separated beam, both are 230 width. Before concreting, when I inspected reinforcement, spacing 2 rebars with 20mm dia. left 100mm only. How can I fix it?

put the button on the outside of the wall.

The answer needs to come from the Architect and/or Engineer of Record. The simple solution for the engineer is to move the call button, but that may not be possible or preferred by the architect. Often times the bar(s) can be cut at the obstruction and bars added on either side that are long enough to act as a non-contact lap splice top and bottom (twice lap length plus obstruction height). Sometimes, the bar can be cut at the obstruction without any remediation. But, it really depends on the design and detailing of the reinforcement. The reinforcing at the intersection can complicate things and prevent these solutiosn. Again, the answer needs to come from those responsible for the design

The call button box is located in a low demand location from a lateral load perspective. And the separator beam is surely designed to be simply supported with a light connection. In summary, The EOR should have an easy time justifying a "do nothing" fix.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

there should be an RFI that the Contractor already started for this before you were asked to inspect it. it didn't sneak up on them. Catching obvious crap like this isn't your role, unless you work for the contractor in a QC role. assuming you don't work for the contractor, facilitating communication between the contractor and the design team isn't your role either, but the role of the RFI-process. you should only intervene in the RFI process when a Contractor does not fully describe the problem.
