What Is Bar Chart In Construction Management?

Using Bar Charts – Bar Charts are the most simple and easiest way to generate construction schedules, It is widely used due to its simplicity and multiple adaptations to numerous events. A bar chart is formed with a list of activities, specifying the start date, duration of the activity and completion date of each activity, and then plotted on a project timescale.

  1. The detailed level of the bar chart depends on your project complexity and the intended use of the schedule.
  2. A variation of the bar chart schedule is the linked bar chart.
  3. A linked bar chart uses arrow and lines to tie the activities and subsequent items, specifying the successors and predecessors of every activity.

The previous activities are linked one to another to demonstrate that one activity must be completed before the other activity can start. Bar charts are useful and used to detect the amount of resources needed for one particular project. Resource aggregation is done by adding resources vertically in the schedule.

What is bar chart explain?

“Bargraph” redirects here. For electronic bargraph displays, see LM3914, Example of a grouped (clustered) bar chart, one with horizontal bars. A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally.

What do you mean by bar charts in project management?

Understanding Gantt Charts – The Gantt chart is the most widely used chart in project management, These charts are useful in planning a project and defining the sequence of tasks that require completion. In most instances, the chart is displayed as a horizontal bar chart.

Horizontal bars of different lengths represent the project timeline, which can include task sequences, duration, and the start and end dates for each task. The horizontal bar also shows how much of a task requires completion. The length of the bar is proportional to the time necessary for a task’s completion.

The project tasks are represented on the vertical axis. A Gantt chart helps in scheduling, managing, and monitoring specific tasks and resources in a project. The chart shows the project timeline, which includes scheduled and completed work over a period of time.

Bar Charts and Its Limitations | Project Scheduling After reading this article you will learn about the bar chart and its limitations. A pictorial chart, also known as the “Bar Chart” was for the first time developed by Henry Gantt around 1900 and is used to deal with complex activities.

The bar chart consists of two coordinates, the horizontal represents the time elapsed and the vertical represents the job or activities performed. The jobs or activities are shown in the form of bars shown in Fig.28.1. The length of the bar shows the time the job or that activity takes for completion.

In every project, some jobs are taken up concurrently and some are to be completed before others can begin. Hence in a bar chart, some of the bars run parallel or overlap each other time-wise and some run serially with one bar beginning after another bar ends.

  • In Fig.28.1 example, activities A and B can start at the same time and proceed concurrently or in parallel, though they take different time intervals for their completion.
  • Activity C begins 5 days after the start of activity A and B.
  • Activity D cannot be started until activity B is over.
  • The bars representing B and D therefore run serially.

Let us consider few examples of Bar Charts: Example 1: Equipment consists of three parts A, B and C. These are assembled together after manufacture. Part A is of cast iron which requires a pattern and a mould, Part B is to be machined on a special machine and hence special machine is to be purchased and erected.

Part C needs special heat treatment before assembly. The assembly has to be tested with a specially fabricated rig before dispatch. The time needed by each activity is given below. Draw the bar chart. Solution: The bar chart for this example is given in Fig.28.2. From the study of the various activities, it is found that activity 1, 4, 5 and 8 can be started concurrently, i.e., at the same time.

These have been indicated in the bar chart. Activity 2 begins after the completion of activity 1. Similarly activity 3 begins after the completion of activity 2. Bar chart shows that activity 6 can begin when the activity 5 is over and activity 7 begins when activity 6 is over.

  • Example 2:
  • Draw a bar (Gantt) chart for the following examination work:
  • Solution:

All the above activities are independent and in the order of sequence. The total duration is 26 days. The Gantt chart can be drawn as shown in Fig.28.3.

  1. Example 3:
  2. Draw the bar chart for the following drawing and printing Work:
  3. Solution:

Here in this problem, activity A, B and C are independent. It means activity B will begin when activity A is over and activity C will begin when activity B is over. Activity D consumes 1 day and this can be started simultaneously with activity C, on the 8th day and thus project completion time will be 8 days. Thus one day can be saved in this way.

  • Example 4:
  • Draw a bar chart for making a chair.
  • The details of activities are as under:
  • (i) Make dimensional sketches of parts – 2 days
  • (ii) Make legs – 2 days
  • (iii) Make seat – 3 days
  • (iv) Make back – 3 days
  • (v) Assemble parts – 2 days
  • Solution:

In this problem after activity (i) is over, activities (ii), (iii) and (iv) can be started at the same time, i.e., concurrent activities. These activities are independent one. Therefore project completion time will be 2 + 3 + 2 = 7 days. Bar chart will be as shown in Fig.28.5.

What is the importance of bar chart?

Vertical bar charts – Bar charts should be used when you are showing segments of information. Vertical bar charts are useful to compare different categorical or discrete variables, such as age groups, classes, schools, etc., as long as there are not too many categories to compare. Data table for Chart 5.2.1 

Data table for chart 5.2.1 Table summary This table displays the results of Data table for chart 5.2.1. The information is grouped by Year (appearing as row headers), Number of police officers (appearing as column headers).

3. TMT Steel – Well, TMT steel is the most widely used variety of steel bars in modern-day building construction. Along with unmatched tensile strength, TMT steel offers many features and properties that other steel bars do not. TMT steel is anti-corrosion, earthquake resistant, lightweight, and easy to assemble.

What is simple bar chart and example?

A simple bar chart is used to represent data involving only one variable classified on a spatial, quantitative or temporal basis. In a simple bar chart, we make bars of equal width but variable length, i.e. the magnitude of a quantity is represented by the height or length of the bars.

What are the types of bar chart?

Types of Bar Graph FAQs – Q.1 What is a bar graph? Ans.1 Bar graphs are a graphical representation of data based on statistics and numerical figures. Bar graphs are majorly used to compare various observations based on a certain parameter(s).Q.2 How many types of bar graphs are there? Ans.2 There are six types of bar graphs based on their structure and the number of parameters they can accommodate.

The six types of bar graphs are vertical, horizontal, double, multiple, stacked, and bar-line bar graphs.Q.3 What are the different types of bar graphs? Ans.3 Based on the structure of the bars and the number of parameters, the bar graph is classified into the following six types. Horizontal bar graph Vertical bar graph Double bar graph (Grouped bar graph) Multiple bar graph (Grouped bar graph) Stacked bar graph Bar line graph Q.4 What is a stacked bar graph? Ans.4 A stacked bar graph also represents various parameters in a single graph.

The difference is that in a stacked bar graph all the parameters are represented in a single bar. So you can say that there are segments of a total in a single bar.Q.5 What is a bar-line graph? Ans.5 A bar line graph is a combination of a bar graph and a line graph.

What is bar chart what are its advantages and limitations?

Difference Between Bar Graphs and Histograms – The histogram or frequency histogram is a graphical representation of data in rectangles with class intervals as bases and heights proportional to corresponding frequencies such that there is no gap between any two successive rectangles.

  • In contrast, the bar graph is a graphical representation of data in bars (or rectangular strip) of uniform width such that distinct data categories can be compared easily.
  • There is equal space between two bars.
  • A histogram is used for the frequency distribution of non-discrete variables, while a bar graph is used for the comparison of discrete variables.

What is bar chart or Gantt chart?

Definition – A Gantt chart is a type of bar chart that illustrates a project schedule. This chart lists the tasks to be performed on the vertical axis, and time intervals on the horizontal axis. The width of the horizontal bars in the graph shows the duration of each activity.

Gantt charts illustrate the start and finish dates of the terminal elements and summary elements of a project, Terminal elements and summary elements constitute the work breakdown structure of the project. Modern Gantt charts also show the dependency (i.e., precedence network) relationships between activities.

Gantt charts can be used to show current schedule status using percent-complete shadings and a vertical “TODAY” line. Gantt charts are sometimes equated with bar charts. Gantt charts are usually created initially using an early start time approach, where each task is scheduled to start immediately when its prerequisites are complete.

What are the benefits of charts?

Key Takeaways –

  • Charts enable you to visually compare multiple sets of data.
  • Charts can help people better understand and remember information. Many people understand a picture more quickly than blocks of text.
  • A compelling chart can help you make your point more convincingly and lend credibility to your presentation.

What is the most important part of a bar graph?

Building Bar Graphs – Bar graphs can be used to show how something changes over time or to compare different times. Bar graphs are good for plotting data that spans many years (or days, weeks,,), has really big changes from year to year (or day to day, The Title The title offers a short explanation of what is in your graph. This helps the reader identify what they are about to look at. It can be creative or simple as long as it tells what is in the graph. The title of this graph tells the reader that the graph contains information about the 2004 unemployment rates of persons 25 years old and older, organized by highest level of education.

The Source The source explains where you found the information that is in your graph. It is important to give credit to those who collected your data! In this graph, the source tells us that we found our information from the NCES Common Core of Data. X-Axis Bar graphs have an x-axis and a y-axis. In most bar graphs, like the one above, the x-axis runs horizontally (flat).

Sometimes bar graphs are made so that the bars are sidewise like in the graph below. Then the x-axis has numbers representing different time periods or names of things being compared. In these graphs, the x-axis has names of states. Y-Axis In most bar graphs, like the one above, the y-axis runs vertically (us and down). The Data The most important part of your graph is the information, or data, it contains. Bar graphs can present data in many ways and can present more than one group of data at a time. The first graph is a regular bar graph with one group of data. The second graph has two groups of data that are stacked.

  1. The last graph is another graph with two groups of data, but they are presented side by side instead of stacked.
  2. The Legend The legend tells us what each bar represents.

Why bars are used in construction?

Why Are TMT Bars Necessary for Construction? – When you talk about important materials used in a building, two materials stand above the rest, these are Steel Bars and Cement. Not only do they provide the extra strength to a building foundation, but also act as a solid reinforcement in RCC structures.

  • There was a time when concrete was a preferred choice of builders, but it had its weaknesses – Was extremely vulnerable to tension though strong in compression and this was an imbalance that the builder’s were confronted with.
  • Thanks to technology, the world today is grateful to have TMT Steel Bars,

TMT Steel Bars not only offer high tensile strength and support to a building structure but they also are highly durable and seismic (earthquake) resistant because of their considerable high elongation property. TMT Steel Bars (Thermo Mechanically Treated Steel Bars), also called as Reinforcement Bar or Rebar in Civil Engineering terminology, are referred to as high-strength reinforcement bars with a tough outer core and a soft inner core.

UNIQUE RIB DESIGN: TMT Bars possess a unique RIB design which helps them to bond better with concrete or cement while also providing them with a superior binding strength EARTHQUAKE RESISTANT: The unique elongation property of TMT Bars gives it the ability to elongate without altering its actual measurement or quality. This is extremely beneficial in earthquake prone areas where it’s used as a construction material CORROSION RESISTANT : The ability to resist rust and corrosion helps TMT Bars to remain stable and workable over a longer period of time, without getting worn-out FIRE RESISTANT : High thermal stability gives TMT Bars the ability to withstand extreme temperatures from 400 to 600 degree Celsius. This will ensure that building’s structural stability stays strong, unaffected by the effects of fire SUPERIOR BENDING CAPABILITY : High degree of elasticity allows TMT Bars to bend when needed for construction purposes SUPERIOR STRENGTH : Hard outer surface with soft inner-core not only makes it 20% stronger than conventional steel bars but also allows it to pass through even the toughest of water cooling systems and stay intense cooled SUPREMELY FLEXIBLE: Incredibly flexible, TMT Bars can be moulded into required steel frames without any effect on its strength and other utility factors LESS RESIDUAL STRESS : Better manufacturing process and latest technology gives TMT Bars an edge over the conventional steel bars, with better tensile strength ENVIRONMENT FRIENDLY : When TMT Bars outlive their utility value, they can be recycled and reused without any loss of quality

Extremely easy to transport due to its lightweight built, TMT Bars with their longer and better durability, and weldability as well as higher tensile strength and better elongation value, enhance the pace of the construction process, while ensuring that lesser steel is used for the same amount of construction.

  • This in turn helps reduce the cost of raw materials as well as costs of transportation and storage.
  • Further, being easier to manage on-site, TMT Bars are extremely cost-effective, while providing for quality cost-savings.
  • For cost-effective and robust TMT steel bars that offer top-notch equilibrium, safety, and stability to the concrete structure, there are a few better names than Vinayak Steels Limited, an integrated steel plant located in Hyderabad, India.

A leading manufacturer of high-grade TMT steel bars, Vinayak Steels Limited offers supreme quality genuine strongest and long-life Fe 550 TMT Bars, which are, today, extensively used in varied construction projects from independent houses high-rise residential buildings to long-span bridges and flyovers, dams, and roads,

Why are bar charts popular in construction?

Using Bar Charts – Bar Charts are the most simple and easiest way to generate construction schedules, It is widely used due to its simplicity and multiple adaptations to numerous events. A bar chart is formed with a list of activities, specifying the start date, duration of the activity and completion date of each activity, and then plotted on a project timescale.

The detailed level of the bar chart depends on your project complexity and the intended use of the schedule. A variation of the bar chart schedule is the linked bar chart. A linked bar chart uses arrow and lines to tie the activities and subsequent items, specifying the successors and predecessors of every activity.

The previous activities are linked one to another to demonstrate that one activity must be completed before the other activity can start. Bar charts are useful and used to detect the amount of resources needed for one particular project. Resource aggregation is done by adding resources vertically in the schedule.

What are the two types of bar?

Types of Bar Chart – A bar chart can be categorized into two broad types, namely; horizontal and vertical bar charts. These groups are further subdivided into the various categories such as vertical stacked bar chart, horizontal grouped bar chart, and the like.
