I agree with the first school of thought. Use your judgement and review the most important items a little more closely. On some jobs, you might only care about the 28 day strength. On others, you may be worried about the 7 day strength, or the add water, or whatever other component could have an...
nutte, I agree with you. I am not attacking the engineer; the engineering design is only one issue of many in a project where excessive problems and failures with a foundation have occurred. The major problems have been with the construction practices. My intent has been to say there were some...
Thank you, everyone, for your comments. I'm actually investigating a foundation that has already been designed and constructed. The engineer designed the foundation without a geotech report and assumed a value for the shear modulus. I am being critical of the original engineer and wanted to see...
I have two questions:
1. What would be a good value to assume for the shear modulus of a sandy clay?
2. Would you ever design a foundation without a geotech report?
Thanks in advance for your help.
If you were negligent in your design, there is no limit. I work in the legal industry and have seen lawyers argue a case that appears to be a lost cause very effectively. I can't stress the importance of good document management. During the discovery period, you start to get an idea of who will...
I am trying to assist a client (owner) by reviewing the contractor's labor rates. A lot of the work is electrical and piping. I'm a structural guy and was hoping to get a little help from the group. Besides RSMeans, are there any other standards I can look to to verify the labor rates? Thanks...
ISO 9001 would be a good place to start. I've worked at a few places that used ISO, and it worked pretty well. As DTOREC said, it requires management; everyone has to be on board and do thier part.
Also, if the budget allows it, you might consider hiring a consultant. You can e-mail me...
The only reason I could see doing this is because you are having making a section of grating work when considering one-direction spanning. I've designed some industrial facilities that have required some extraordinarily hefty grating and I've always been able to find a section that would work...
I am trying to put together an estimate for a concrete repair project. The project consists of injecting concrete columns with an epoxy resin. RS Means shows a production rate of 80 lf per day. I need to estimate what percentage of the labor is spent on prepping the concrete, injecting the...
It is my understanding from the original post is that the plate is in the field but nothing has been installed yet. If that is correct, scratch the idea of the 3/4" studs. Instead, weld a HSS section to the plank and cantilever the HSS out to the plate. Also, I would not put the expansion anchor...
Adding to my above post ... the masonry would have to be anchored at the top and bottom. Otherwise, you are just getting a stiffened section (again, assuming that there is a mechanical attachment between the masonry and steel).
The project was in Texas. I believe the contractor does have a construction lawyer for this issue. As far as the specifics, I'm not too sure. I think the total construction time was around a year. The big problem from the owner's standpoint is they had tenants ready to occupy the building at a...
A contractor that I work with often recently completed construction on a mid-rise office tower. The final construction was completed approximately three months behind schedule, due to a variety of issues. The owner is trying to hold the contractor liable for lost revenues, while the contractor...
Even though the masonry is "perfectly tight" to the column web, I wouldn't count on any restraint unless there is some sort of mechanical anchorage between the steel and the masonry.
Maybe I don't understand your question, but all you have to do is design the rebar in the same manner you would design it for the tension in a bending member.
The geometry of the two buildings will be important in deciding how to design the add-on. If the addd-on is very small in comparison to the existing structure, the new loads may be negligible.
Also, again depending on the geometry of the add-on, it might be possible to resist the transverse...
I usually just do buildings, but right now I am working on a light rail track slab. I would like some advice on constructability issues for the slab. The overall depth of the slab will be approximately 24". Should I design the slab as a monolithic pour or should I include a cold joint to the...
