Hello.
You certainly are embarking down a costly road. Firstly because this is a structural project, you will need to get in touch with a certified engineer ( to do all of the structural drawings and size your steel beams and set your post spacings as well as tell you where you need to install concrete pads below the floor to support your new steel beam). At this time he will also set the size for the lvl beams as well as your continuos post support to either the foundation or to the concrete floor in your basement where you will once again reinforce the floor with concrete pads to support this)and your local building department.
After you get this information you need to find a repudable contractor with the necesary wsib and proper insurance. Then contact your insurance because they have to know what is going so that the proper coverage needs to be put on.
Timelines are a guide and almost never get followed. Depending on what your contractor gets into it could take from 2 weeks to 4 weeks to complete the work that you need done.
With high quality products and considerate service, we will work together with you to enhance your business and improve the efficiency. Please don't hesitate to contact us to get more details of 24 ft lvl beam price, Lightweight Steel Props.
