Optimal timing
Considering optimal timing of project
monitoring and control points is significant to success (Falco and
Macchiaroli,1998). Falco and Macchiaroli suggest that we should
determine the optimal frequency of the monitoring and reviewing to
different activities in different stages. It can help us to efficient
monitor and correct control so as to reach time and cost target.
Crashing
In
recent years, network crashing was developed along with the project
time control method (PRC ) for planning and controlling large scale
project. The purpose of crashing is the minimization of the pessimistic
time estimate in PERT (Program Evaluation and Review Technique) networks
by investing additional amounts of money in the activities on the
project time control . Sometimes, crashing methods are required to
combine in the monitoring and controlling process when the duration of
the activity that has to be completed within a specified time (Abbasi
and Mukattash,2001,pl81).
1.4 RESEARCH QUESTION
Is Probabilistic
moment of risk: An activity (task) in most real-life processes is not a
continuous uniform process. Tasks are affected by external events, which
can occur at some point in the middle of the task.
Why is it that
event chains: Events can cause other events, which will create event
chains. These event chains can significantly affect the course of the
project. Quantitative analysis is used to determine a cumulative effect
of these event chains on the project schedule.
Critical events or
event chains, is it the single events or the event chains that have the
most potential to affect the projects are the “critical events†or
“critical chains of events.†They can be determined by the analysis.
Project
tracking with events: Even if a project is partially completed and data
about the project duration, cost, and events occurred is available, it
is still possible to refine information about future potential events
and helps to forecast future project performance.
1.5 SCOPE OF THE STUDY
The
best means of ensuring that the costs are kept to a minimum during any
project is by utilizing a commercial construction costs management
service. This is an establishment which is able to realistically look at
the capital costs for any commercial building construction project.
They not only look closely at the planning costs but also cost control
services. Plus this service will ensure that the proposals provided on
the construction project are documented as well as being completed
within the pre-arranged costs and time framework. They will also
establish the most economical means of ensuring that the project does
not run over budget. Each construction project should employ an
independent and professional cost manager or quantity surveyor who can
police as well as have a clear overview of everything that is going on.
This is to protect the financial interests of the individual who is
having the construction project done. These people use their engineering
skills and experience which they then apply to scientific principles
and techniques. This allows them to analyze and develop the best action
that should be taken in order to provide a good estimation of the costs
involved. This will also enable them to control the commercial building
construction costs once the project starts on site. By using a good set
of cost management principles the cost manager or quantity surveyor will
ensure that the construction project stays within the budget limits and
still meets performance and quality targets. When a commercial
construction project is being prepared the cost manager or quantity
surveyor is an integral part of the team and can bring added value to
any construction and design team. However if there are problems relating
to commercial building construction costs exceeding the budget, then
this may well cause problems for the person who was asked to control the
costs initially.
1.6 SIGNIFIANCE OF THE STUDY
Engaging a general
contractor or construction manager earlier in the process is a good way
to control time in the initial planning phases. These experts
understand all legal requirements and can ensure all documentation is
filed methodically and in a timely manner, reducing schedule delays
early on. Some building owners are taking a more active role in the
overall process and are functioning as a team member to streamline
communications and drive faster completion of projects as well.
Developers and business owners should encourage these approaches and
work with general contractors, who have good relationships with
established suppliers. This enables them to increase their aptitude to
project and budget construction costs accurately through to the end of
the building construction process.
