When I am sitting on the couch I can feel the 30lb dog bouncing across the room yes he bounces.

They are listed on the structural drawings as not required. Thoughts on this? Would I be better off opening up parts of the ceiling and adding blocking or cross bracing between thinking this might be the same effect as the strongbacks being installed.

Charlene, you are concerned about installing basic things in your kitchen. I am an engineer in California and if your home was desgned to code, these things should not be a problem. The code requires that all floors in a residential home be designed for dead load plus live load. The standard code live load is 40 psf. The normal dead load most engineers use are about 15 psf to 20 psf. This includes the weight of the floor framing, plywood sheathing and permanent partition walls.

This way of design is usual adequate to handle all residential floor loads. Above this is an exterior deck which will most likely remain dead load maybe some chairs in the future but not much.

With that being said, has anyone experienced such an issue with sprinkler issues? Looking at a house with the open web floor truss — looks like there was some sagging and the owners have installed additional steel supports posts in areas. My guess is they went too far of a span.

This deck will hold a grill and table and up to 8 people at most at one time. I am very cost conscious but I want a long lasting safe deck.

Also will have a second floor. I wish to put a floor in an outhouse for storage. The size will be 6 m long and 8 feet wide. Can you advise as to whether this would be the right size, whether spruce or pine would be ok.

The floor is to store various household items. We need to be able to walk on it to get access to the items stored. I want to build a underground house. What kind of joist should i use. What spacing and what size boards will I need? I too want to build an Underground home with earthbags and a sloping flat roof. The snow load spec for the area calls for 50 lb load per square foot for starters and I want to put only 1 foot of soil on top.
