RFI for additional support members required
Does a detailer care about supporting the elements which are not available in the structural design, but it could affect the structure? You should care!
See the below incident for an example.
STRUCTURAL PLAN This structural plan has sections 1 & 2. Refer below snip for section views.
STRUCTURAL SECTION VIEWS 
DETAIL-A WITH PARAPET SUPPORT If you see the above snap, Section 2 has detail-A, which shows parapet wall support. But section-1 does not have it.
Is that means there is no support required?
Actually, there is also support required.
Refer below architect plan.
ARCHITECTURAL PLANWe have noticed that the parapet coming all around the roof (Highlighted in Pink Colour). So we raise RFI regarding this issue for taking it to their attention. Refer below snip.
RFI RAISED BY TEK1 REGARDING PARAPET SUPPORT The client realises the situation and approves providing parapet support members all around the roof. Refer below snip for the client’s response.
RESPONSE FROM THE CLIENT We always keep our client’s out of trouble from these types of issues.

Can you spot the problem#10
Initial Structural design 
Arch design Did you find anything missing from the above Design?
The Roof has slopes. But there is no consideration for gutter provision and its support.
We figure out this issue and raise RFI against this issue.
RFI regarding the missing consideration of Gutter and its fixing Client approves to make changes in the design and send us back. See below revised design
Revised Structural Design -
Selection method for Reports Creation in Tekla
While creating reports in Tekla Always ensure that selection men must be in objects selection. See below snaps
OBJECTS SELECTION 
COMPONENT SELECTION Above snaps clearly states reports must be taken while the members selected in objects selection option is turned on. Otherwise the report quantity will be less than the actual quantity.

Can you spot the Problem#9
ARCH PLAN & RCP Can you find any discrepancy from the above Structural and Arch design Snaps.
Hope you got it.
Profile of beam B1 is150UC30 from the structural drawing.
The beam comes below ceiling. It would not be an issue if the stud wall accommodates the beam. But, the thickness of the stud wall is only 92mm and the beam is 150UC30. The beam will be accommodated neither within the ceiling nor the stud wall.
So, we have changed the Beam B1 profile from 150UC30 to PFC200*75 to accommodate the member within the 92mm thick stud wall and asked for confirmation.
We attached model snap for better understanding to the Client.
MODEL ELEVATION SNAP Client understood the issue we encountered and agreed to change the profile of the Beam B1.

Can you spot the Problem#7
When we place a beam, we need to consider several factors. The major one is to ensure that the beams do not clash with any of the aesthetical members such as the Cladding, Roof sheets, wall panel etc.
In this figure.1 The engineer has provided a UC150*37 beam as 1B30 to support the external beam at perimeter and stud wall. If we fix the beam as per the architects specified location it will clash with the external wall finish (NASAHI WALL) by 40mm which is shown in Figure.2. We can not move this beam from its location because the supporting columns are hidden inside the walls for the aesthetic purpose by Architect.
Engineer provides 150UC37 AS 1B30. Also, Architect prefers 50 thick NASAHI wall finish at the Perimeter. 
Model Snaps Shows the beam Clash with NASAHI wall. So we have no choice but to rather change the beam profile, This condition was explained to the Engineer and Architect by our detailer.
The requirement was to change beam profile to be concealed and at the same time support the framework, thus was modified to PFC 200*75.
As we change the beam profile the clash was eliminated Always be vigilant about these factors to avoid major mistakes.
