So after you do the calculations of this table, we go to drawing the line of balance. And from drawing the line of balance, what I would need here To be able to draw is column number six, seven, eight and nine for all activities. If you would notice here, because it's very narrow, line d here It has an activity duration of 2.19, so that letter D is not showing here, but this one is the production rate The production line of activity or process D. And it has the actual output rate 4.56. That's why if you notice I draw it more To the steep towards activity C because it's faster in the production rate. So activity A here then, if we want to draw that Numbers on the line of balance, we say that the point here, which is the end of the first section in process A or activity A, would be 4.58. Because activity duration of the first unit. So the thickness of each of these lines will be given by column 7. So in this case, what would be that point in time in the X axis here on this point? Which is the start of the last Section of the road on activity a, as we mentioned we can bring it from column number 8 here is 29.05. So in this case when are we finishing the last section on a process a And the line of balance example would be here the 29.05 plus the duration, the thickness of A, which is the 4.58, then it will give you 33.6 That when you approximately finishing all the sections on your project for process eight. So moving forward, We look at both Process A and B. Process A has an actual output trait of 3.27, and process B has an actual output trait of 3. Because, as I explained to you before, if we have activity B, the following activity With slower production then, the buffer will be in the bottom. So, this gives me more to add here, around five days so, we can say that This point in time here, at the line of balance of B would be 4.58+5 days as a lag or the buffer. So tell us It tells us that the first section of the road, we start to perform process b on 9.58 days after the start of the project. So moving forward, what- What can we identify here. The schedule would be that thickness of the line or the duration of one section from the table we have it as also five. So we take the 9.58 + the 5 which equal 14.58. And we move forward. B and C, C has lower 2.96, lower actual output rate than B of 3.00 Then the buffer will be also in the bottom. So five days buffered plus when the 14.58 then it will give you 19.58 Which would be the start of activity c of the first section of the project. And the end of that specific section of activity c would be the duration of c Which will be 5.07 plus the 19, where is the start date, 19.58. 24.65. So between C and D Before we move forward, I highlighted, what do you think the last section of the project, when are we planning to finalize that last section from activity C. It would be the same as column number eight, which will be that 24.65 the finish of that first activity, to the finish of the last activity of C or first section to the last section which will be The 24.65 plus the 32.11 for activity or process C because column eight, we can read it as the time from the start on first section to start on last section. Or the time from finish on first section to finish on last section because the start to the finish, the difference between them is constant, which is the activity duration. From column seven. So that being said, where the buffer will be, between activity c and d? We will look at activity d, The actual output rate is 4.56, the slope Is faster that activity c so we'll the buffer on the top as the following five days. So the start of the last section on the road on activity d, Would be 56, 176 plus the five days, And then moving forward, we can find when that will finish which is the duration Of that activity. D on that one section, the last section, which will be 2.19 as we can see from the table here. And then moving forward We will be able to find the number here, also, based on what I just explained from column number 8, either from the time from the start. Can we have it from the end to the end From both activities. In this case we have 63.95, the point here minus what we going to get from column number 8 to find that finish time of the first section of activity D Which is 20.83 here, will give you the 43.12. And then the buffer also will be the bottom between E and D, because E is a slower Than d. So the buffer, we set five days, so we have 5 plus the point in time when we finish the first section of the project on activity d. Then, we can have the duration of activity E, which is 5.25 plus 48.12, the duration here. Plus the thickness, which is the activity duration of e, and then you can find when you going to finish the last Section in the road for the last process which is E here. Which will give you then 53.37 from here plus from column number 8 33.22 then it will give you 86.59 then that number would be then the total number of project time. So that is the align of balance example We have for a repetitive construction of 20 sections and 5 processes or construction activities that repeated for each of these sections. All the numbers, if you just follow the equations that I just highlighted and develop the table first And B is on column number 6 here. You just roughly, approximately put the lines on, identify where is the buffer is going to be. B is on column number 6 which, one activity will be speeding up or not. And avoid any intersection Between all of them and make them as parallel and balanced as possible, then you will identify your line of balance schedule for your repetitive or linear construction project. So to wrap up our module, for the line of balance Schedule in my humble opinion, in construction it is not that common, but we do use it a lot, sometimes in manufacturing not in construction. So if you would notice there is a lot of trends happening towards manufacturing Not constructing in a controlled environment and after you manufacture a small sections, a of sections. And then ship them to your project to assemble them and building them and integrating them within a project. That's why I want to highlight the line of balanced schedule that can help more in building or manufacturing industry or building units within your project. We use it a lot also in recession development or research. Goals to understand the repetitive nature of a linear construction projects. So, again, it is not that much common that's why I would love for you also to more focus And you the majority of you will find an activity on node, and that's the most used between all the almost globally. With that being said, we finalizing here, our module for the and the line of balance
