Its a fiscal year and I am busy. This is the time when I  can learn a lot of things in my field. I have been busy learning and helping my senior engineer- learning to prepare the Interim Payment Certificate (IPC) and helping draw some of the on location drawings. I have a lot of improvements to made both in drawing and hunting for the most probable mistake anyone might make. It was a real fun and worth doing when it comes to work. The job not new but it comes in with new surprises for me each time learning an additional information that I need to judge if I am in right or heading towards a wrong path.

The first thing that has to be done for the preparation of  IPC in a road project is the As Location drawing where all the drawing of the finished structures are made exactly the same way as they are constructed in the site with their proper dimensions and fit them in the cross section. Then comes the earth work calculation for the respective drawing. It remind me of those college days when we calculated the earthworks even without cross sections. They were supposed to be our estimated earthworks; but no earthwork without the cross section of the particular location. I learnt how to use AutoCad to find the earthwork in excavation and area of Masonry. I get a sense of satisfaction to have this opportunity to learn something. After all the drawing works is complete them comes the preparation of the format for the data entry in IPC. The quantity is calculated using the area from the Cad program and multiplying it with the length from the Back elevation. The location where the height changes Average area method is used to calculate the quantity. Hence the earthwork, formwork, Concrete in PCC and  Masonry Quantity are  calculated respectively. The rate of each item is then multiplied to calculate the amount. It seems easy when I say here but quite a lot to work out to get the accurate IPC.

Here is the copy of  sectional drawing that has to be made before preparing IPC.
