LOOKING FOR STEEL DETAILING PROJECTS.

LOOKING FOR STEEL DETAILING PROJECTS.

                  

Why you need to choose 2907 BM LIMITED GROUP for below reasons?

           AISC STANDARDS WITH OSHA CODES , ASD AND LRFD DESIGN CODES.

• Having more than 13+years of experience in executing steel detailing projects 
• strong team with 20 members who can handle the project with high quality.
• Good communication skills for all the group members in team.
• All the companies need good coordination in team so that projects will go smoothly that is the good thing what we have in my team.
• RFI preparation and way of approach for making a question is a major concerns in a team but my team is so much skill full in that without a doubt i can say.

Short and sweetly I can say we are looking for long term relationship with big fabricators like you. I am hoping i will get a positive reply from your end.

Please reach us with quotes to tekladetailer2907@gmail.com. I request give me an opportunity

to show my team skills and good quality of work.

Thanks

IMPORTANT TABLES TO BE FOLLOWED WHILE CHECKING DRAWINGS.

 1.ANCHOR BOLT 14-2 TABLE.

2.EDGE DISTANCES CHART?

3.HOLE DIA CHART?

4.ENCROCHMENT CHART?

5.MAXIMUM AND MINIMUM NUMBER OF BOLTS?

6.ANGLE GAGES?

7.GAGES FOR WF BEAMS?

8.WELDING CHART?

9.WRENCH CLEARENCE CHART?

Just 3 questions..

 1.what is the hole tolerance for epoxy anchors?

 Answer:up to  1/2" dia bolt -1/8 tolerance ,if we are using more than 1/2 " dia bolt then we need to use hole tolerance as 3/16.

2.what are the OSHA standards for a column?

1.In perimeter columns we need to provide safety cable holes for safety purpose.

2.column splice should be 4'-0 from finished floor.

3In splice columns we need to provide a lifting hole for lifting purpose.

3.In design drawings if we dnt have connections then what to do?

For shear connections ,we need to refer Aisc table based on the end reaction loads and based on the type of beam whether composite or non composite ,We have charts in Aisc manual.

From AISC tables we need to design the connections and need to cloud in approval.

Other than shear connections,we need ask client for connections.

Steel detailing Question paper -11

 1.What is the full form of SEOR AND JBE?

SEOR: Senior Engineer of record.

JBE: Joist Bearing Elevation.

2.If Slab thickness 8" but embed plate size is 9" ,what to do?

SOL: We need to accommodate embed plate only in side the concrete if it is projecting out of slab

  then we need to reduce the Size of embed plate to match with the slab thickness.

3.If we have dimensions for operable partition in design drawings,Will you release drawings for 

  Fabrication?

NO,Without receiving final partiton drawings set don't release drawings for fabrication.

4.If members are getting field weld then what to take care in Shop Drawings?

We need to give no paint hatching for members where its get field weld,Also we need to give 2" extra hatching

5.While placing a grid ,What are main step you need to take care?

We need to compare grid dimensions between structural drawings and Arch drawings,If dimensions are  mismatching then we need to raise  RFI .

6..What is the Size of long slotted hole for 1" and 1.5" dia bolt?

For 1"-1 1/16x2 1/2

        1"1/2-1 9/16x3 3/4

7.If suppose W member workable gage 2 "1/4  but design drawings shows to 3/4" bolt ,Is it workable?

No,

1.If we follow  3/4"dia bolt  then bolt will enter in to the encroachment.

2.There will be an edge distance problem. 

So we need to reduce the bolt size to 1/2 dia then we need to take confirmation from client.

8.What is Backgouging?

It is a method of chipping out and filling of the weld on the farside of CJP.

9.Derive E70XX?

E-Electrode.

70-Tensile Strength.

X-Weld position.

X-Electric current used.

10.What are the components of handrail?

1.Top rail

2.Midrail

3.handrail post.

4.Toe plate or angle.

Anyone need estimation of projects feel free to contact me -tekladetailer2907@gmail.com.

While checking anchor bolts,what are the important points to be taken care?

      1.Bottom Of Base plate elevation to be finalized from design drawings

       2.If we use plate washers ,We need to follow over sized holes in base plate i.e 
          for example: if we use 3/4" Ø anchor rod,Hole dia should be 1 5/16"Ø.

      3.Plate washers sizes should be followed for AISC 14.2 table.
         for 3/4"Ø anchor rod , we will follow plate washer size as 1/4"X2X0'-2".

     4.Plate washers is used to cover the over sized holes.

     5.If design drawing does not furnish levelling method pattern then we need send to
         rfi on levelling method,Mostly we will use levelling nut or levelling plate  arrangement.

         we will use levelling plate thickness as 1/4" and we will match plate parameters  to base plate size.

    6. Template : Template is used to match accurate position of anchor rods,Generally
       Template thickness we will follow as 1/8" and we will match length and width as  base plate  size.

    7.Grout hole: If smaller side dimension of the base plate exceeds approximately 2'-0 then we will provide grout hole in base plate.

    8.column schedule to be referred properly ,So that we will exact base plate sizes and  anchor rod dia.

   9.if design drawing does not provide embedment  then we need to calculate embedment 
    by using formula  i.e 12 X Diameter of anchor rod.
   if we use 3/4"Ø then embedment is 9".

  10.If design drawing does not provide projection then we need to calculate projection by 
     using  formula i.e Grout thickness + base plate thickeness + 2 times of anchor rod dia  
      +washer thickness + nut thickness.

  11.We need to identify footing depths properly because we should maintain 3"clearence 
     between bottom of anchor rod and bottom of footing.
     some times in order to maintain footing depth ,We need to deviate embedment values 
     and also we need to ask question for confirmation.

      

 

AUTOCAD BASICS INTERVIEW QUESTIONS

 AUTOCAD BASIC  INTERVIEW QUESTIONS

1.WHAT IS AUTOCAD?

Autocad is  a  computer  aided  designing software which is use  for 2D and  3d  designing  and detailing .

Autocad  is  developed by Autodesk. 

2.WHAT ARE  THE  ADVANTAGES OF AUTOCAD?

• Provides accurate drawing.
• spares time and build the  efficiency .
• We  can provide quality  drawings  with  decorated  hatches.
• 3D models can be done  for  representation.
• Modifications can  be done easily.

3.WHAT ARE THE FILE FORMATS USED  IN AUTOCAD?

• DWG file format used in Autocad.

4.WHAT IS  TEMPLATE  IN AUTOCAD AND ITS USES?

6.WHAT IS THE LAYERS IN AUTOCAD AND ITS USES?

Layer is a object management system by which we can separate the object's in a drawing according

to their functions.  

For example creating a wall in a different layer and for door also separate layer is required.

Layers are used to control the visibility of objects and assign properties such as color and line type.

7.WHAT IS WORKSPACE IN AUTOCAD AND HOW MANY WORK SPACES ARE AVAILABLE

Work spaces are set of user interface components such as ribbon tabs and pannels , toolbars, palettes

and menu bars ,that are grouped and organized.
