Minum check List 2

  1. Update clients on ETA of drawings. Constantly. Clients love status updates, and learning where their jobs are currently at.
  2. Update line items when they are ready to be invoiced. If you don’t, how can you invoice your clients? If you don’t invoice, then how do you expect to receive payment for your work?
  3. Follow up on RFIs that are not answered: push the job forward. Clients are relying on you.
  4. Changes to a drawing? Please markup the REASONS for changes to a drawing. Use markup links if appropriate. If you don’t do this, clients might be confused as to WHY. Especially applicable if a client instructs a change to be made, but the change was not made as instructed.

Checks Prior to Detailing

  1. Compare the quoted drawings to the drawings you are detailing from: are there any differences – if there are differences then: (i) send a report to the client noting the differences + (ii) send the mark ups + (iii) send any extra steel required. Add these to the extra billables. If there are not differences, then please send an email to the client saying: there are no differences + add your report. You must always send a report, regardless of whether there are differences or not. Add in your reports here: https://docs.google.com/spreadsheets/d/1zmO_dBpxX-ajwoKL0Z-8lgD33I-gQcv6pVp05iBlQqg/edit?ts=5e4577f6#gid=972410357
  2. Evaluate Site measure requirements.
    • Is Steel Fixing to concrete- Get Concrete site-measured, or sent the concrete drawing for approval. Ask for photographs and site measure

  22. Bolt Check. Run the Bolt Check Macro (newly added in checklist on 14/3/17)
  23. Number setting – Is the name ticked. Name must be ticked because the bridging list depends on the name to get the bridging Number. At the very least the while numbering bridging Name should be ticked. The main Part must take Assembly Mark. (This is required for beamline Marking) (new)

  10. Provide iso metric Assy view for complicated assemblies.
  11. Default weld is 6mm fillet weld. All other welds must be called up in Assy drawings.
    Welds should be modeled correctly. We cannot model all welds as 6mm fillet weld. If the drawing calls for 8mm weld, it should be modeled as 8 mm weld.
  12. Brick lintels are usually stitch-weld. Make sure the note is on (New) 13/3/2020

Checks while modeling (Main Modeller)

  1. Did you read Steel Notes and highlight points to note.

  4. Curved beams Handle to the outside of the radius. Verify using drawing at the modeling stage.
  5. Test Assy drgs creation. Drg should come right side up
  6. For CHS with end cleats. CHS rotation matches with End cleats.
    • (Procedure. Set UCS to end cleat front)
    • Set CHS rotation degrees to zero. (CHS main part)
    • Create Assy drawing and make sure end cleats are not rotated.
  7. No items modeled as folded plates except for parts which will require folding while manufacturing (Sheet metal only)
  8. No base plate showing up through walls. or projecting into doorways. (Check-in Arch Plan View)

Grating Checks

  1. Load bars need support.
  2. Check maximum span. If the span is more, then additional support is required.
  3. FRP GRATING 
    1. For FRP grating there is no dominant load bar direction
    2. For FRP grating support is required for all direction of load bar
    3. Span cannot exceed the specification in both direction
    4. Do not mark load bar direction for FRP grating

Bent Plate or Angle

When possible use Angles because

Bent plate is more expensive, more time

GA Checks

  2. DO NOT MIRROR COLS, BEAMS PLATE. You can mirror points and construction lines(new)
  3. Bolts to Timber (Only Holes to be provided since bolts are not supplied by fabricator)
  4. Standard welds are 6mm fillet welds. All other welds must be modelled correctly and called in shop drawings.
  5. Don’t Draw unnecessary walls and other elements which has no impact with our scope of work.

Modeling checks for Houses

  1. Can door open. The sliding door must open without clashing with steel col or base plate.
  2. Lintels should extend to each side to support brickwork.
  3. Garage Lintels must support the brick above the door. (Usually with a plate welded under the beam)
  4. Slab must be modeled correctly prior to starting modeling.

Facia Purlins

  1. Angle of the Facia Purlins should be specified to match with Roof Angle
  2. Facia Purlin Must have a drawing
  3. Check bracket hole distances. Bracket specifications are different for Facia purlins. Check against Lysaght catalog

Modeling checks for Stairs.

  1. Is there a site measure required.
  2. Is the site measure to concrete, have you considered floor covering.
  3. Ask for the rise and going on the last nosing point. Because landing may have different thickness flooring.
  4. Are the handrails stainless? The maximum length of the available stainless steel pipe in 6M.
  5. How is the pipe to pipe connection? Will inline splice be used? Check https://stainlesscablerailing.com/ss-15-splice-inline.html

Bolt Checks (New)

  1. Provide Blue Color for Chemset Bolts – Tolerance 4 mm
  2. Provide red color for bolts through Galvaniszed members – 4 mm tolerance on Galvanized plates.
  3. Take a Bolt Summary sheet. Check Bolt sizes
  4. Put a filter on Galvanized items. Check hole sizes for 2 mm tolerance.
  5. Special Attention for CSK bolts. Check DXF.
  6. Do not supply bolts at timber connections. Model holes without bolt option.

Dxf files

  1. Do not provide centerlines for holes
  2. Open and check dxf files. Especially plates with CSK holes, since there is a good chance that we can make an error.

Setting out site measure

Minimum 2 Points should be aligned and identfied in drawings and model.  One point is not enugh.

How we have used the site measure should be clearly shown in the drawing

Site measure should never be scaled. If the .dwg file turns up with no units, then set the units as appropriate to mm or meters. Never scale meters to mm or in anyway modify site measure. Site measure should be used as is

Clouds and RFIs on IFA and IFC drawings.

  1. All clouds on IFA drawings should be numbered.
  2. Project History sheet must have all the clouds which are in the drawings.
  3. Clouds status should be coloured in as open, or closed.
  4. Clouds should be removed only if satisfactorily closed.
  5. The pdf of open cloud list should be sent along with IFA drawings.
  6. Reason for removing clould should be listed in the Project History sheet.
  7. If client insists on getting issuing IFC drawings without answering clouds, do not remove clouds. Send IFC along with list of open clouded items

Chequer Plate Checks

  1. Check in model all plates are drawn front. Put drawings early on to check plate rotation
  2. Architectural plates must not have scribe marks on visible face
  3. The Bend line should be visible in dxf.
  4. Use correct material. Material used affects developed length
  5. Chequred plate dxf should be created with backside up. Bend lines should be present in dxf.
  6. Always open dxf and check.
  7. If CSK holes are there, then make sure that the holes cut are only for the bolt size and NOT the head size.
  8. Check whether smaller holes are cut. Sometimes, we need cut small holes in dxf. Sometimes we need to cut. Check requirements and check the dxf.
  9. Make sure the settings for dxf is correct.
  10. For cutting Stringer plates, contour marking for cleats is required. So Check wether the countour markings are coming on dxf.
