I was asked about the best way to brace a gable end wall with a lot of windows. It is 2x6 construction with pre-engineered trusses with a vaulted ceiling. Attached is a picture from the outside and I will post of a couple from the inside. Would installing a plywood ceiling on the vaulted...
Does the crack in the attached picture pose a structural concern? I did a septic system design for a client and he has asked me about the crack but I don't have much experience with concrete cracks. Thanks for the advice.
Designing a beam to be installed in a basement for a two story house using forte software.
For the loads should I make the floor live load 80 psf (40 psf + 40 psf) or use two separate loads (each one with a 40 psf live load). The tributary width is the same and the load bearing wall on the 1st...

One of the requirements for a pool at a rv park is that the re-circulation system has to be designed so that velocities do not exceed 6 fps. Based on the pools size and that the entire volume has to be circulated every 6 hours I have determined that the circulation rate needs to be 118 gpm...
I am designing an addition for a client and he would like a balcony on the upper level. It is a 24' wide addition so the floor joists will be spanning 12' from a wall in the middle of the addition to the exterior wall. He would like to go 8' out but the cantilever distance would be greater...
One of my clients called me and said the contractor really screwed up his basement concrete slab. He had some cores tested for psi and it was found to be 1,500 psi. Is there a way to fix this other than removing the entire slab and re pouring? The contractor also failed to install a vapor...
I did some structural work for a client and he asked me about installing a 2,500 foot water line from the town main to his building. The building is approximately 70' above the water main. Will a 1" plastic water line be big enough?

A contractor asked me if he could offset the beam in the basement about 4" so it is not directly under the 1st story load bearing wall. The reason he asks is that he wants to run his plumbing down the wall but if the beam is directly under the wall he can't. He said he always ends up building...
Some replies in my other post got me thinking about ventilation in a crawl space and freezing issues. By code you are supposed to have ventilation in a crawl space. How do you prevent the plumbing from freezing if there are vents in the crawl space? Are the vents just closed/blocked off...
