After two years, they find out the business doesn't run properly. So, they decide to rent the place out. The new tenant, who has a pizza franchise, strip all the walls and floor. What does he find? In the middle of the store, there was a load-bearing post removed! It must hold a wall that all the way through the second floor. The previous reno crew maybe thought that it was something useless!!
The customer asked us for an immediate action. We got there to investigate the situation. In a certain point, the main store's ceiling dropped around five inches! The joices can tolerate loads to a limit; if it maxes up, they will break and the ceiling will be collapsed.
We hired a well experienced "civil engineer" and a "professional engineer" (P. Eng.). We got the permit, jacked up the ceiling to get a true level, made two temporary load-bearing walls, installed a beam that made of three 18' by 12" LVL glued/nailed/screwed together and two support jack posts being installed, each in one side of the beam (made of 2 by 8). we put those support posts on top of the main brick load-bearing wall to have a structural bonding.
