The parameters of measurement of success of any project-time, cost, safety, quality and customer satisfaction can be severely affected by construction delays (Shujaa Safdar Gardezi, 2013). This study investigates various factors affecting the timeline of the schedule by various participants in the project, followed by mathematical analysis to propose that the major reasons for delays are the domestic issues of the country.
2.1 Current techniques for the analysis of delays Following are three different modes of application of delay analysis techniques based on their simulations with fundamental schedules:
1. Direct Analysis
Direct analysis involves examining the available schedule information without doing any simulations and modifications. Therefore, it is relatively simple, easy, less time consuming and a lot less expensive to perform.
2. Additive Analysis
In this methodology, the delays are added to the schedule as individual activities to simulate the actual scenario of occurrence and reflect the effects of the delays on the as-planned schedule. The additions of the delays can be performed individually knowns as single stage analysis as well as in multiple schedules also known as multi-stage analysis (Trauner, 1990). Some of the examples of additive analysis are time impact analysis, impacted as-planned, window analysis and as-planned but for.
3. Subtractive Analysis
In this analysis, modifications and simulations are carried out on the as-built schedules in a backward
Why it is important to conduct a comparative analysis of Event, Chain with other traditional methodologies and investigate how it contributes in being Successful scheduling techniques in Project Management discipline?
Describe common practices to estimate the duration of project activities as well as real reasons that cause project delays.
Concurrent delays can be used in both the offensive as well as defensive ways. Contractor uses concurrency as a shield to defend himself against fiscal damages by the employer. On the other hand employer uses it to ward off the contractor 's pursuits for delay costs. Therefore, this topic has been going through a lot of research. United States Court of Federal Claims described the notion of concurrent delay in R.P. Wallace, Inc. v. U.S. 63 Fed. Cl. 402 (2004). ). There are many players in construction affecting the construction schedule; but, following are the three major examples of the concurrent delays:
Quality metrics are very important components of any project process. In essence, the metrics are important indicators of the overall progression of a project. Using the quality metrics, it is much easier to establish the proper corrective steps needed to be taken for a project. The Pizza Delivered Quickly case study made up of several phases that have been subsequently subdivided into six subsystems. There for, the overarching efficiency of this project is reliant on the integration of very important quality metrics. This type of a framework will facilitate for the project assessment and also it’s positioning towards the primary organizational goal of improving performance. All the subsystems of PDQ can profit greatly from the PMLC models. The logistics subsystem can be trimmed greatly by using the agile project management methodology. In addition, PMLC models like the traditional approach can be interspersed into all phases of the whole PDQ project. Quality metrics are very important barometers, which can be used to trim the capability of the new computer systems for PDQ. The aforementioned conditions form a crucial aspect of analysis in this case study. The analysis also centers on the materialization of the trigger results and the pertinent PMLC models for multiple projects in the case study.
The simulation is useful because it evaluates project performance using real criteria, such as the scope, schedule and
1 Malcolm will follow instructions given to him by PS and LCCC staff. - Mostly met. Malcolm follows task-oriented instructions given to him by staff members. 2 Malcolm will improve on his time management skills. - Mostly met. Malcolm's attendance has improved since his last EPM. He has been absent only one day since then and emailed his manager that morning.
Activity D lies on the critical path, therefore the early start date is 8/17/2012. A task that is aligned on the critical path with a "finish-start" orientation must start immediately after its predecessor activities are completed. Any delay of a task on the critical path directly extends the date of project completion.
Construction Engineers, within three (3) Calendar Days of the start of any delays to the Critical Path that are caused by actions or inactions that were not within the control of the Contractor. Delay notifications that are not provided in a letter to the Engineer, such as a delay notification in the schedule narrative, will not be recognized as contractual notice in the determination of any Time Extension related to the impacts to the work associated with this specific alleged delay.
Critical path analysis is a method that is used to plan out the many activities involved in a project to be able to find the most efficient way of complete it and how to complete it on time.
First thing in the Analysis model is Study of Existing System, which is available. Without Study of Existing system Analysis Model cannot proceed.
If there is a 2 day delay during activity H, there will be no delays on overall project because we have 2 days float on
In the aggregate planning module we have added a model to create a transportation problem. For assembly line balancing we have added a display that summarizes the results when using each of the methods. For decision tables we have added an output display for various values of alpha when computing the Hurwicz value. Our most exciting new addition is that in decision analysis we now have an easy-to-use graphical user interface to create the decision tree. In addition, we have added a new model for creating decision tables for one period inventory (supply/demand) problems. In forecasting, we have added a model that allows the user to enter the forecasts in order to run an error analysis. In addition, we have added the MAPE as standard output for all models and added forecast control with computation of the tracking signal. In inventory we have added the reorder point models for both normal and discrete demand distributions. In job shop scheduling, for one machine sequencing we have allowed for inclusion of the dates that jobs are received and we have added a display that summarizes the results when using all of the
Thus the output of the model is the truck schedule, i.e. from which origins to schedule the trucks to the destination, satisfying the total demand at each destination.
In field of project management, there are a plethora of mechanisms under perpetual reevaluation. One specific segmentation of project management under such scrutiny pertains to cost duration, which is the time and monetary costs of completing individual tasks within the project’s critical path (IBM Knowledge Center, 2016). The process of monitoring and evaluating the time and financial impacts of each task is referred to as cost duration analysis (IBM Knowledge Center, 2016). A chief concern of cost duration analysis is identifying tasks within the project’s critical path which can reduce project duration (PMI, 2013). A common approach to reducing a project’s duration is task “crashing” (PMI, p.181). According to The Project Management Institute (2013) crashing refers to the process of methodical determining the financial value of increasing a critical path task’s resources in order to decrease project duration (p.181).
Why the project manager get some trouble with the scheduling maybe because of they do not use the software enough and CPM was overkill for small project with little cost justification. Owners were also concerned as while their preference was to use Primavera as the required software specified, that their experience was that many contractors still use MS Project which has limitations and does not allow the owner to perform the monitoring that it desires throughout project execution (Galloway, 2006). For those owners using linear scheduling techniques, their primary concern was that few contractors understood this scheduling technique and that it was not well known in the
