Repositioning of Metal beams (Tamuning)

Hi,

I have metal beams supporting a wooden loft which needs repositioning in Tamuning commercial building.

The square beams are 6”wide and positioned about 4feet from each other

. I want it to be about 17’apart. In order to do so, engineer told me I must insert a supporting 8”beam right below the loft. I’m looking for quotation and need to do this next week. Pls call me at 4830507 for Sarah.

Thank you,

Sarah
