I'm not aware of anything legally that would restrict you from providing a DD or preliminary design. There are a variety of reasons why an owner would want to do this and I'm sure there are some unethical reasons as well.
1) We have provided partial design sets for owners as part of a...
Our office (full service A/S/M/E/C) does this with a spreadsheet that is updated monthly. In a nutshell the process we use is as follows:
Each project manager reviews their projects indicating the anticipated revenue and effort by each department that every project will require for each of the...
I see more and more structural firms having the engineers do both the design and the drafting.
If you're looking to someone else to provide drafting for your design then you'll most likely want to go the route of a draftsman. While the money may work for an engineer to do your drafting...
What environment will the rebar be exposed to? Recommendations would vary depending on whether this is in an interior conditioned space or an exterior space or exposed to chemicals, etc.
My experience would be that when an individual gets licensed there is an increase in the person's pay.
While some of it may be the increased liability you have sealing work as a professional engineer, the reality is a lot has to do with the increased value that comes to your company. Billing...
The north wall is non-load bearing. There is a gable end truss directly above the wall. There is a small roof overhang. Outriggers are attached to the first truss south of the wall and cantilever over the gable end truss.
The studs are bowing max. at mid-height. The top plate is directly above the bottom plate so there is no lean to the wall.
The bowing is outward and was not there when initially installed.
My understanding is that the house was erected last winter and siding/roofing was put on immediately...
I was asked about some LSL wall studs that are bowing and I can't figure out the cause so I wanted to see if anyone else could provide some insight.
House is 42'x32'. Roof trusses (vaulted) span across the 32' dimension with gable ends. Bearing walls on each side are 15' tall. End walls (non...
I have been asked to look at an existing framed ceiling supported on partition walls. The walls are 3 5/8", 25 ga. drywall studs. Is there any documented load carrying capacity of these studs?
My recommendation is the Hilti. We have an older model, but it would be comparable to the PD-I model on their website. For long distances or exterior shots it could be beneficial to have the optical viewfinder on the PD-E model. When you're taking long shots it can be difficult to see what...
My only additional comment would be to make sure and consider connections from the RTU down through the roof (ductwork, piping, etc.). If your elevated roof top unit will have supply and return ductwork that extend down from the unit through the roof this may impact the ability for wind to blow...
Generally I would approach it with one (or all) of the following:
1) Contact your local offices. If they are unable to help ask them for a recommendation. Generally the engineers know others that provide the type of engineering to meet your needs.
2) Contact the manufacturer. For racking...
I am designing the foundation system for a metal building. Due to poor soils and large building loads (100' spans and bridge cranes), the building will be supported on auger cast piles. The outward thrust of the exterior columns is ~30 kips. Additionally the high interior slab loads may cause...
Another option to consider would be drag struts. Given that your client doesn't want tie-beams, I don't know if he would sign off on using these. Even though they would only extend into a portion of the building.
In the projects I've seen drag struts they tend to be trenched soil cast grade...
I have been asked to design the framing for a sculpture. The frame is generally welded angles with a steel plate skin. The skin will be weathering steel. The interior support angles are being proposed as A36 painted (except the base angle). My main questions have to do with the base of the...
I will say that I always assumed I would start my own consulting business. When my child was diagnosed with serious medical issues I assumed that I would never work on my own. In fact, the need for medical insurance was the reason that I changed jobs from a two man office (what would happen to...
My recommendation would be to buy technical digest 12 "Evaluation and modification of open-web steel joists and joist girders" from the steel joist institute. You can purchase this as a pdf.
It outlines how you can use bar joist load tables to determine adequacy for additional loads and how...
I have seen a concrete drag strut used rather than hairpins or direct ties. Basically a reinforced concrete grade beam cast perpendicular to the pad footings extending into the building. The lateral restraint is the friction along the sides of the grade beam. When I have seen this used it has...
