If framing within the metal plate connected wood trusses are the concern, then I recommend having the specialty structural engineer who sealed the truss design drawings assess them.
WoodWorks may be of some assistance in finding an expert but I would not be too hopeful.

We are designing a mobile platform (see attachment). The client has indicated that the platform will be used by maximum of (2) workers at a time. We are intending to use 300 lbs to account for a worker + tools.
OSHA requires we design the platform for 4x the maximum intended...
There is continuous grout and rebar in the keyways between adjacent panels. Panels are 4' wide. Below is plan view showing this grouted keyway.
We have directed them to remove the masonite board, our concern was how much grout will follow into the hollowcore voids. Our detail specified a plug...
Please see the photo from the pre-pour and out typical detail below. We had specified to use core plug to keep the grout from penetrating into the cores. The contractor did not order these in time and is now proposing to use masonite board as shown in the picture below.
We believe there is an...
We recently received a deferred submittal for an aluminum canopy that is cantilevering from our our structure (HSS girt), see image below.
In the Design Criteria, the signed and sealed submittal had the following notes:
"Roof maintenance not permitted during design event(s) as roof live...
In our market composite steel beams with concrete on composite metal deck is a common framing system, however it's cost increases dramatically on smaller projects (footprint less than ~10,000 SF) due to many reasons with one being the cost of renting the Nelson stud guns to install the shear...
The AHJ does not allow RCP for wet wells over 6'Ø.
I have spoken with a few contractors in the area who have done it this way albeit for much larger tanks. They cast the sections in a starter pit and then sink them by excavating out the interior. This is still referred to as the caisson...
I am designing an 8'Ø x 26' deep x 10" thick wet well. I have studied the PCA publication "Circular Concrete Tanks Without Prestressing" however the H^2/Dt values provided in the charts don't come close to meeting my calculated value (89.3).
Is there another resource or is my only option to use...
I have a 8'0" wide double door with a loose lintel above that is supporting brick veneer. The backup wall is CMU. Should I anchor the loose lintel into the masonry lintel in order to transfer suction forces or it is standard practice to rely on the brick ties? Is another option to design the...
Thanks Swiver. I agree, I will not be ready to venture out on my own after passing the PE. I feel that I would need around 8 of experience before even considering it.
All,
Every year I get glowing reviews from my project managers telling me that I am exceeding expectations and ahead of the pack in regards to my peers, however I do not feel that this is being adequately portrayed to my boss whom I have never worked with directly. I am basing this on the fact...
All,
I am going to be giving a presentation to first year graduate engineers about the construction administration phase of a project. In order to provide concrete examples on the importance of the CA phase I was hoping to use some specific example of when a major design flaw was caught or...
Are there any guidelines or code statements in reference to what are acceptable CFMF attachments to structure? I have a steel building that has exterior stud walls. In the shop drawing the studs are shown attaching to the bottom of wide flange beams for lateral support. We did not account for...
Received a geotechnical report for a project site that has expansive clay soils. In the report is states that the belled pier capacity is to be reduced when the spacing of the bells is less than 3 bell diameters (clear space) based on the larger pier. The reductions are 40% for 2-3 diameters and...
This is a composite deck with 4½" of NWC on 3" deck. The typical detail that we call out shows expansion anchors, the contractor was asking for a substitution which I wanted to have a good answer for him besides just saying no. The composite deck was designed for a 7 K point load (forlift...
Is there any concern with welding a steel angle to 18 GA deck via fillet weld (1/8")? My initial thought it no since the deck is only .0478" thick. I believe the weld will burn through compromising the strength of the deck...
