10th Week Day 3~5

Helped Ms. Inez in checking of markings schedule and column markings.
o Check the drawing to match the value in drawing with given data.
o Check the label of column to match with the label a floor below it.
o Create an excel spreadsheet to ease up the checking and data finding.

Above is the formulised excel spreadsheet screenshot

For the excel spreadsheet I have created, I have to include recommendations to client, such as Revision required on Pile Group Design, Recommendation Length and Reduction of length.

According to a senior engineer, we cannot ask them to change their pile as we are only consultant and whether to use our recommendation is up to the judging of developer. The reason for this is because if we force them to use certain length of pile, the responsibility will be ours if the foundation fails.

10th Week Day 1~2

1) Continuation of guardhouse design from Ms. Shiao Teng.
o Column design was done this week and I have learnt that the design of column relies on a simple formula, which is :

N = 0.35Fcu Ac + 0.7Fy Asc

Where:
N = Total Axial Force on the column
Fcu = Concrete Compressive Strength
Fy = Concrete Steel strength
Ac = Concrete Area
As = Steel Area

o The spacing of shear links cannot be more than 12 times the diameter of the reinforcement bars.

2) Slab Design of guard house using MTM.
The Output, A8, B5, etc is the label for mesh design require for the slab.

· The solid line is the bottom reinforcement for the slab

· The dotted line is the top reinforcement for the slab

9th Week Day 1~5

Learned how to design guardhouse from Ms. Shiao Teng.

o To design a guard house, we need to check criteria as below:
§ Usage of guard house : Determining the loading
§ Check the architectural drawing and check the dimension of beams and columns proposed in architectural drawing.
§ Check the continuity of beams.

Overview of Guardhouse Plan

Helped Ms.Inez in checking of pile markings.

o Check the loading of pile after adjustment in borehole log.
o The borehole log will determine the SPT-N of the pile which is how many blows required by the pile driver into 1.5m of soil. Usually, N above 50 is not recommended as it will cause the pile head to fail.
o The SPT-N usually get higher when we go deeper but sometimes the SPT-N will get high and suddenly drops again. This is due to existence of hard soil layer in between of normal soil. Hence, when going through the hard should, more blows is required.

8th Week Day 5

Software Study : PROKON.

o This software is all-rounder software that can do modelling and analyse the structure (Quite similar to StaadPRO). PROKON have more interactive features that allow user to visualize the actual elements used in structure and the design is more accurate as they have different tabs for various types of design required by engineers.

Picture above shows the modelling of structure done by me.

From the figure above, we can see that PROKON is capable of modelling and also analyse a structure. PROKON can calculate:
o Deflections
o Support Reactions
o Beam Forces
o Shell (or Slab) Moment and Forces
o Moment on Beam
o Moment on Shell(or Slab)

8th Week Day 4

Revit Software Demonstration.

The Revit Building Maker feature provides a more seamless way to turn conceptual forms into functional designs. Select faces to generate walls, roofs, floors, and curtain systems. Use tools to extract important information about your building such as surface area or volume per floor. Conceptual forms may be created natively in Autodesk Revit Architecture or imported from applications such as AutoCAD®, form-Z, Rhino, Google® SketchUp®, or other ACIS- or NURBS-based applications into Autodesk Revit Architecture software as mass objects
