Direct Analysis Of Construction Delays

In this literature, I found that the choice of time representation is an important parameter in the structure and character of a mathematical model for scheduling. There are two types of time representation - Discrete and continuous. I also learned about the Decomposition algorithm which is used when the complexity of the problems are high. I understand and try to formulate the problem given for continuous and discrete time formulation for the comparison of two models, results and

Describe common practices to estimate the duration of project activities as well as real reasons that cause project delays.

Event chain methodology, a new way of scheduling is an uncertainty modeling and schedule network analysis technique that is focused on identifying and managing events and event chains that affect project schedules. Event chain methodology helps to mitigate the negative impact of psychological heuristics and biases, as well as to allow for easy modeling of uncertainties in the project schedules.

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.

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.

Research is conducted to examine different points of views of the importance of performance outcomes in a construction project in Hong Kong. ANOVA was used to analyse the data relative to how the performances were measured. Performances were measured using a performance criteria starting with the most important first, which is time. Timely completion of a project would prevent loss of revenue and penalities to the contractor.

Set an ambitious but not overly optimistic target completion date, according to resources invested and management’s targets. In case of delays, readjust target completion date.

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.

This research paper is focused on one of the biggest concern of the construction industry in today’s world, which is “Construction Delay Claims”. A construction project consists different individual or interdependent activities. There is a higher possibility that some sort of delay might occur in any of the involved activities. In order to mitigate issue of delays and make delay claim resolving process easier, researcher and engineers came with an idea which is know as “Critical Path Method (CPM)”. CPM would have different activity paths but among them the longest path (based on time duration) is known as critical path. Critical path is also known as “Zero Float Path”. Float is a certain extra amount of time allotted to activities which can be utilized before or during that activity. It can be understood that any delay in the activities that are on critical path could cause overall project to be delayed. Though delays are quiet common in construction projects, it is necessary to determine whether the delay is critical or not. Once the criticality of the delay is decided then the responsible party for the delay is determined. This is the basic logic behind all the construction delay claims assessment methodologies. Key tools in the assessment procedure are As- planned schedule and As- build schedule for the project. As- planned scheduled is the schedule submitted by the contractor to the owner prior to the construction work starts. As- build schedule is the schedule which

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.

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).

The major of using technology that help discovering how companies are using CPM, the past theory stated the benefits obtained from CPM application. The theory in 1974 gave six different options for benefits including improved estimating, improved planning before work starts, improved project control after work starts, faster response to problems, improved communication among the work force, and cost savings (Kelleher,2004). Other than that, more benefits were added to the survey such as improved scheduling, helps train future project managers, positive psychological effects on employees, and time savings. This method can give more benefits including improved understanding of the project help project complete on time and run smoother, minimizes disputes, and more control over risk and uncertainty. According to Callahan et al,. (1992) mention the important because the 1983 study showed that delayed projects are closely related to disputes. The majority of owners also felt that a significant cause of cost overruns was due to poor scheduling on the part of the contractor. Construction schedules can reduce delays cost overruns and disputes).

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
