Here we are going to explaining about the thing needed to focus on ARCH CONC SETOUT PLAN for precast detailing
- Panel Set-out & width:
-
- Mostly we prefer to use Precast Set-out from Conc set-out but before proceed with this drawing , we need to raise RFI to Builder to confirm this Drawing need to follow for this entire project.
- If panel set-out, dimensions, openings annotate on conc set-out means use that value.
- Please look over for special indication that denotes architectural patterns
- Slab RL:
-
- SSL value is provided on conc plan with respect to top profile of slab.
- Slab step downs/ step up profiles are specified in this plan by its RL values and some special legends
- Slab thickness:
-
- Some architects, they clearly specify their slab thickness in concrete setout itself but we need to confirm that slab thickness with structural drawings.
- Some architects, they clearly specify their slab thickness in concrete setout itself but we need to confirm that slab thickness with structural drawings.
- Parapet/spandrels/window &Door RL:
- In most of the cases spandrels top RL specify in this plan
- In some case, for parapet wall (top of wall)RL should take from this plan
- In some case ,sill RL and header RL for window will be given in this plan
- In some case ,sill RL and header RL for door will be given in this plan
- Overflow location :
- Overflow need to provide at balcony/terrace areas
- Location and size of those overflow can be taken from precast panels concrete setout
- If overflow location not provided we need to raise TBC for overflow location.
- Slab / wall peno location:
- Penetrations are require to provide for varies purposes
- Service penetrations at slab
- Service penetrations at wall
- These penetration locations and sizes are need to take from this plan as well as elevation.
- Penetrations are require to provide for varies purposes
- Profile Type:
- Slab profiles are determined and highlighted in special legend.
- Those determined profiles are classified as different types and provide it in a separate drawing
- By study those type and legends, sometimes we need take slab step ups/downs values and nominal folding values for slab profile.
- Alimak /loading platforms/ Hoist locations:
- Those void locations are helpful in providing breakups and panel erection type
- Alimak are type of material transport car, used to transport building materials to all levels. Where alimak is present we can’t erect precast.
- If panel locate at alimak/loading platform /hoist, it will affect construction materials transportation.
- So some modification on construction process will require at those locations ,precast may also be changed to in-situ and some cases it can be as post –fixing panels
- Breakups also need to consider while doing marking plan.
- Pattern Groove Set-out:
- Pattern groove set out – some rare case only, architect show pattern groove set out in conc plan. (Mainly refer architect elevation)
- If they provided it will more helpful in providing panel breakup, based on groove only we need to provide breakup for panels in continues elevation.
- Ramp profile:
- Ramp slab: Data’s provided for ramp in two ways
- Ramp profile increasing ratio (percentage) will provide between two points, length will be measured between those two points
- Starting point and ending point RL’s will provide between two points, length will be measured between those two points
- If additional ramp sections provided, then we also need to consider it.
- Ramp slab: Data’s provided for ramp in two ways
Above data’s will provide in conc setout plan. We need to take those data and work it out for exact ramp profile of slab
- Slab boundary line:
- For slab boundary line, we need to refer slab extent in conc plan
