For the fabricator, bent plates are more expensive to produce in low volume. So when you want a bent plate, in low volume ( less than 50 pieces, go for welded plates). More than that please raise an RFI. When you are detailing please note this one.

St. Benedict’s Stage 7 Hall, Oran Park
Raj (Arokiaraj Arputharaj)
St. Benedict’s Stage 7 Hall, Oran Park, is a multipurpose hall structure.
St. Benedict’s Catholic College was opened in 2011 on a greenfield site in Sydney’s south west suburb of Oran Park.
There are seven stages of construction work listed below.- Technology and Applied Studies (TAS)
- food technology
- covered outdoor learning
- science
- staff administration
- library
- creative and performing arts
- general learning areas
- multi-purpose hall
TEK1’s scope was Muti-Porspose Hall, and works included anchorbolt steel columns, beams, braces, and purlins.
TEK1 raised multiple RFIs with a proposal. So the design got revised according to the RFIs.
The client responded to TEK1 RFIs quickly.
The project was completed quickly by our team.

Getting the Drawings Reviewed
Drawings are always submitted for approval before fabrication. When any changes are given by the structural engineer or the architect, after implementing the changes, the drawings must be submitted again for 2nd approval so that the structural engineer & the architect will review & approve the drawings.
In some cases, the architect & the structural engineer skip their duty of reviewing & question the detailer whether the detailer has implemented all the changes. Refer below image for an example.
In such cases answering with a “yes” might cause trouble to the detailer & the corresponding concern in he future.
Rather than answering the question, the detailer can pose a question to the question asked like “Have the Structural Engineer and Architect approved?”.
By such way, the detailer has attended to the structural engineer or the architect and also the duty to review the drawings has also been assigned once again to him.

Lets learn Some Erection feasibility Checks
Things to be checked, if we get a spigot connection for a column
When we have a spigot connection, at top of the column and a base plate connection at bottom of the column, first we must check the clearance provided for the movement of the column in the spigot to avoid any difficulties during erection.
If the clearance is not sufficient, we must address the issue to the client along with some proposals. In our condition the following Suggestions were provided.
We can postfix the Chemsets at any one side of the column ends
We can increase the clearance to enable sufficient erection clearance for the column.In the below case, the design demands to pre-fix the chemset bolts and have provided only 50mm clearance for the spigot movement.
Refer below snaps from model & structural design.
In the above snap, the bottom of column has 10 thick base plate with Ø12 Chemset bolts and the top of the column is connected to the slab through the spigot which has 10 thick top plate with Ø12 chemset bolts as per the structural design requirement.
The structural engineer advised to pre-fix the chemset bolts.
So, we need to check for erection clearance to install the column.
The clearance between Soffit to the top of slab is 2940mm (Refer model snap). When we deduct the projection of the chemset at top 30mm (10mm top plate thick + 20mm projection) and at bottom 45mm (15mm grout + 10mm base plate thick + 20mm projection) from the slab to slab clearance (2940mm) we get 2865mm (2940-30-45=2865).
But the length of the column (when the spigot is fully inside the column and the top plate only projects out) is 2865 (column length) + 10 (Top plate of spigot) = 2875 mm which is 10mm more than that of the clearance between chemset projections.
So, considering this 10mm extra length and providing 15mm clearance at top and bottom, we have prepared a markup proposing 50mm (clearance as per design) + 40mm (10mm extra length of column + 15mm clearance on top & bottom) = 90mm spigot movement for easy erection and this proposal was sent to client.
Client had understood the issue and agreed our connection proposal with 90mm clearance.
Our analysis towards erection possibility along with client’s attention and understanding of the issue that we have addressed made the columns easy to erect.
