I'm working on my first big precast job (parking garage), here's my situation:
A 24"x24" PC column needs to be supported on a 5'-0" CIP pilaster above the ramp at the 1st floor. It's supporting the entire building. I've designed the pilaster to be slightly oversized (40"x24") to avoid...
Say you have a research facility with vibration-sensitive equipment, and it's immediately adjacent to a train track. Ground borne vibrations are induced on the structure. It is being proposed to provide granular material ("riprap") under the spread footings to help mitigate vibrations. Does...
I get this RFI on just about every project:
"Please provide the dimension off line 'x' for the W12x19..." supporting the RTU curb. Fabricators get insolent because they can't "finalize" shop drawings without these dimensions. We'll get the cut sheet from the MEP for a TRANE unit with...
We are being asked to perform a structural peer review of a project for one of our long-time clients (although the project in question was not designed by us). We do not do many of these, and my boss was trying to locate a standard scope of services, structural review checklist, or something...
I have a load bearing masonry wall supporting a hollowcore plank floor system in a 3 story hotel. At the second floor, two of my bearing walls cannot continue down since the architect doesn't want any bearing element in his lobby for some strange reason. So I'm thinking of using a transfer...
Could anyone point me to a website or a reference where I might find a comprehensive table of European Steel Sections and Properties (similar to Table 1 in the AISC manual)?
Or do I have to buy a manual? If so, which one? I've never had any experience with steel design outside of American...
Let me first just state that I am a structural EIT. I have not taken, nor passed, any PE exam. And I believe it's laudable for everyone that gets their name on a stamp. But, let me stand on a soap box for a minute...
I have many friends that graduated with the same civil engineering...
Disclaimer: I tried to post this in the concrete general forum, but I received no response. I haven't checked the Alexa ratings, but I'm assuming more people peruse the "other topics" forum. so here goes...

I'm working on an unbonded PT parking garage in chicaco. Our concrete spec calls for a microsilica admixture for corrosion protection. The contractor submitted an RFI asking if a Grace DCI corrosion inhibiting admixture would be an acceptable subsitute, on the basis that the microsilica mix...
Is it permitted to run an electrical conduit in the concrete floor slabs of composite steel beams? If so, how does one determine or specify an amount or size of conduit permitted? What if a large amount of conduit crosses perpendicular to a beam at either the center span, where compression is a...
I have back-up angle framing for a perforated metal panel used as an architectural feature that I specified to be hot-dipped galvanized. The contractor has asked if he can apply a "1-part zinc primer" in lieu of hot-dipping. For one, I have a hard time believing this would be more cost...
