BLOB can be used wherever a java.sql.Blob is expected and an oracle.sql.CLOB can be used wherever a java.sql.Clob is expected. If Activity B has a productivity rate of 1 week per floor, then it can begin work at the end of the second week. Fig. However, starting from 16-Nov-17 the R.C columns crew will join the R.C slabs crew to finish faster, can we do this scenario? However, during one of my training sessions with new engineers, we discussed the line of balance method, and I asked them to explain it to me as they understand. The Aluminium formwork system was developed by W.J. The team size who would finish the pc footings in 9 days, could finish the R.C columns in 6 days, but the slope of the S.O.G is 12 days which means that there will be intersection between these two teams. The work areas that define the project are represented along the y-axis. It differs from a bar chart which shows a particular activity’s duration, by showing the rate at which the work has to be undertaken to stay on schedule, as well as the relationship of one trade or process to the subsequent trade or process. This is one of the main benefits of the Line of Balance Method, in this case we will start our calculation from the top.

The duration between the first start and last start is 111 days, if we divide it by the number of units we get 11.1 day per unit. BLOB and CLOB Classes. Similarly, I can re-use the same crew of the R.C footings to execute the R.C slabs. We will draw the Plain concrete works under footings, each building will take 10 days to be completed, so it is a straight forward process. So now we know each unit when the PC under footings should start and when it should finish.

For example, Unit No. LOB is used on repetitive work such as constructing multiple dwelling units, when used on linear work such as roads and railways the technique is more accurately called Time/Location Charts or Chainage Charts which include ‘blocks’ to mark out chainages such as bridges and culverts that require substantial time to build and interrupt the general flow of work.
