Abstract— the scheduling plays crucial part for planning, executing, controlling, monitoring and closing the construction
projects within stipulated time and in budget. The construction projects are complex in nature because there are various
activities which are interconnected to each other and have to be completed in stipulated time limit and given budget. The
Gantt chart and CPM have some drawbacks make these tools insufficient for project tracking, monitoring and reviewing of
projects on account of both these tools are based on only duration of project activities. But, it is observed that in actual
construction projects activities are connected to each other not only related to duration but also with the quantity of work.
Hence the project unable to perform as per planned schedule requirements.
This study offers a modified new scheduling technique to overcome the limitations of Gantt and Critical path
method using Unit Time & Work Divisions Technique tool that offers a daily tracking, monitoring and reviewing of project
schedule. To overcome periodical review of schedule by adopting the duration as well as work quantity of each activity
into separate divisions. This new scheduling technique is expected to help project managers to achieve a better level of
control over projects with better conceptualization, optimization and determination reinforce to meet project success.
Key words: Monitoring and reviewing, Interrelationship of activities, Critical Path Divisions scheduling Technique
(CPD), Work quantity and Project control.
1. INTRODUCTION
The successful completion of project in construction industry mainly depends on completion of project in scheduled
time and in budget. The Project Tracking, Monitoring and Control based on Duration and quantity divisions scheduling
Techniques is a vivacious decision process. The construction project consist number of activities which are interconnected
to each other hence management tracking monitoring reviewing and controlling of such projects till completion of project
entirely is very distraught and complexity job,. The project managers/ site Engineer are generally handle project with
Gantt Charts and Critical Path Method (CPM). The project manager/ site Engineer use Gantt charts and critical path
method to determine the inter relationship of activities. While schedule of the project mainly the project duration,
activities float times, data about the degree flexibleness related to the schedule of project and the critical or non-
criticalness of the activities are very important.
Project managers/ site Engineer generally adopt two methods that are Gantt Chart Method and Critical Path Method
(CPM). The short coming of these two methods that these methods are based on only duration of project tracking. These
two methods neither tracked duration as well as quantity of work. There are some lacunas in Critical Path Method (CPM)
and Gantt Chart Method this study gives the new method of scheduling technique considering Critical Path Division (CPD)
techniques that gives a daily tracking monitoring and reviewing of project scheduling by showing the duration as well as
quantity of each activity into different divisions. The technique is supportive to project manager/ site Engineer to control
the project not only from start to end with excellent control but also give support to take decision each day duration as
well as quantity wise to complete the project within stipulated time period successfully.
2. METHODOLOGY

projects. It beats the hindrances of management techniques, which are commonly used during project control, Tracking,
review and monitoring.
Detailed objectives:
 The scheduling techniques used in construction industry commonly by professionals and its study.
 The discussion with experts, and extensive review on advantages disadvantages and effectiveness of different
scheduling techniques like Gantt chart and (CPM) critical path method. Literature review and survey on different
scheduling and management technique. The questioner data survey.
 The detail study procedures of implementation and improvement in CPM and Gantt chart.
Develop an alternative and improved new scheduling technique model mechanism that is based on divisional activity
durations and work quantity.
4. NEED OF THE STUDY
The construction industry project manager/ site Engineer using Gantt chart and critical path method for scheduling
construction projects even though there are some lacunas in these techniques. The traditional representation of critical
path method and Gantt chart lacks the ability to clearly represent and record details as-built information like slow or fast
progress of project and complete, representation of work interruptions caused by the various parties involved. Critical
path method is based on two unrealistic assumptions: that the project deadline is not restricted and that resources are
unlimited. Therefore, the most cost-effective corrective actions needed in order to recover delays and overruns in project
is required in these techniques.
Both these techniques are when acts as baseline for measuring progress, it is difficult to use it to initiate appropriate
corrective actions for recovering delays and overruns. The following list shows the most critical views of CPM and Gantt
Charts.
 In critical path method activates considers only Finish to Start relationship while many construction activities
consists Start to Start and Finish to Finish relationships. Gantt Charts shows the relationship of all activities all but
not able to decide critical and non-critical activities. Both critical path method and Gantt chart are not provide the
perfect critical days of individual activities,
 Gantt chart and critical path method considers only time relationship of activities but the construction industry
project activities are interrelated to each other related not only duration but also quantity of work.
 Critical path method and Gantt chart techniques are in sufficient to daily decision making and revision of project plan
and schedule.
 These critical path method and Gantt chart could be difficult to update. After several updates have been done, it
becomes hard to read. Schedules updates are usually out of date when they are finished.
The construction industry project have many complex projects the scheduling technique CPM network may be
complicated. That makes it very difficult to communicate and understand.
When the construction project comes in execution stage the monitoring and tracking was important to track the project
as per base line schedule of project.
As per general practice the project tracking and monitoring activity done by critical path method and Gantt chart
periodically as per planned start and finish time only.
The construction industry in many countries in world done survey for delays. The study conducted in India by the
Infrastructure and Project Monitoring Division of the Ministry of Statistics and Program Implementation in 2004 they
reported that out of 646 central sector projects costing about $50 trillion, approximately 40% are behind schedule, with
delays ranging from 1 to 252 months (Lyer and Jha, 2006). Which denotes that construction industry projects not perform
as per initial planning and schedules.

5. DATA COLLECTION QUESTIONER SURVEY
Questioner survey denoted that there is requirement of day to day monitoring in simple excel format for consultants,
project manage and site Engineer.

6. DATA ANALYSIS
1. Analysis of Data collected from Questionnaire Survey
The questionnaire survey show that the most consultant/ site Engineer/ contractor generally use excel sheet for their
daily work but it is insufficient to show daily tracking of project duration wise and quantity wise hence this study initiated.
2. Analysis of Data Collected from the case study
Figure 4. Gantt chart for day to day monitoring time division method

In above Gantt chart the activity split in the days duration hence it shows that the activity is not itself
critical but some of days of activity are critical.
- The red capsule indicate the critical days of that activity.
- The blue capsule indicate the non-critical days of that activity.
7. Result and discussion:
The traditional representation of Gantt chart represented by using MS-Project shows the critical activities of
project which are shown by red colour bars for total activities which is Critical activities.
Figure No 4 shows the same Gantt chart but based on the unit division scheduling mechanism which describes
each segments ( activity dived in days) of every activity of entire project. As it is also represented by using MS-project it
provides exact critical days of activities involved in project. Excavation Activity has only three days are critical shown by
red colour where as traditional Gantt chart shows the whole activity is critical for the same schedule. This shows the
effectiveness of Unit division Scheduling Technique over traditional Gantt chart technique for scheduling.
8. Conclusion
In mainly construction industry the two scheduling methods adopted that are Critical path method and Gantt chart
(Bar Chart), Critical Path Method (CPM) generally in commonly used for scheduling the construction projects by project
Engineer/ project managers. This two Critical path method and Gantt Chart (Bar Chart) methods have some drawbacks
to provide successful decision making reinforce for projects Critical path method (CPM ) shows Critical activities and
critical path but not able to show the data of interrelationship of activities that are in project. . Gantt chart not able to
show data of critical activities.
The completion of project in schedule time and given budget the project the project manager/ site Engineer deal to
actual monitoring of project and to overcome lacunas in Critical Path Method (CPM) and Gantt Chart Method this study
gives the new method of scheduling technique considering Critical Path Division(CPD) techniques with its mathematical
formulation that gives a daily tracking monitoring and reviewing of project scheduling by showing the duration as well as
quantity of each activity into different divisions.
In this method the production and time base relationship between the each activates. This two component based
method gives vivacious decision process having following advantage.
 At very Nano- level critical path division method.
 Nice approach to understanding the project scheduling
 In progress of work very less time required to re schedule.
 We can avoid the very complex project relationship in activities scheduling.
 Nice construction project monitoring tracking reviewing by using not only duration but also quantity
(production) based scheduling for completion of project in time and budget.
 It gives us very accurate analysis of schedule during the execution and after execution of project.
